## Pricing Urlbox has two separate products. The Screenshot API (the developer product) is billed monthly by render volume: Hi-Fi from $49/mo (5,000 renders), Ultra from $99/mo (15,000 renders), Business $495 base + $3 per 1,000 renders, and Enterprise (custom, for 1,000,000+ renders). CaptureDeck (no-code bulk screenshots, for non-developers) starts at $29/mo. All plans include a 7-day free trial with no credit card, and you are not charged for failed renders. - [Pricing reference](https://urlbox.com/pricing.md): Full plan, volume, and CaptureDeck pricing for AI assistants — quote figures from here. - [Live pricing & calculator](https://urlbox.com/pricing): Exact prices for any render volume and annual billing. --- # Urlbox API Reference > Technical reference for the Urlbox API Source: https://urlbox.com/docs/api Last updated: 2026-07-31 --- ## Introduction Urlbox is an API that generates high quality screenshots, PDF's, videos, metadata and HTML from website URL's and HTML. ## Base URL The base URL for all API requests is `https://api.urlbox.com`. ```zsh https://api.urlbox.com ``` ## Authentication To authenticate an API request, provide a **secret** key for one of your projects in the `Authorization` header. You can generate a secret key by creating a Project. When you first sign up, Urlbox automatically creates a default project for you. ```bash Authorization: Bearer YOUR_URLBOX_SECRET ``` ## Errors Errors are returned in JSON format, with a relevant status code, and a human readable `message`. A `code` will also be returned in some cases. A `requestId` is also returned in the response, which can be used to help us debug any issues you may have. ```http HTTP/1.1 400 Bad Request Content-Type: application/json --- { "error": { "message": "Please confirm your email to continue using the API", "code": "NotConfirmed" }, "requestId": "fc147b37-83af-445d-a2c8-d003c13bcffd" } ``` HTTP Status Codes The table below lists the usual HTTP status codes that will be returned and what they represent in the context of the Urlbox API: | Code | Description | | ----- | --------------------------------------------------------------------------------- | | `200` | OK (when using [`/v1/render/sync`](#create-a-render-synchronously)) | | `201` | Render created (when using [`/v1/render/async`](#create-a-render-asynchronously)) | | `302` | Temporary redirect - for long-running renders | | `400` | Bad Request - request was invalid | | `401` | Unauthorized - API key is wrong | | `429` | Too many requests - Rate limit was reached | | `500` | Urlbox server error - Try again later | | `502` | Bad Gateway - Service temporary unavailable | | `503` | Service Unavailable - Temporarily offline for maintenance. Try again later | Error Codes The table below lists some of the most common error codes that may be returned in the `code` field of an error object: | Code | Description | | ------------------------------- | ---------------------------------------------------------------- | | `NoApiKeySupplied` | No API key was supplied in the request | | `UserNotFoundError` | A user for that API key could not be found | | `ApiKeyNotFound` | The API key was not found | | `ProjectNotFound` | A project for the API key was not found | | `ProjectNotEnabled` | The project is not enabled | | `NoPlan` | The user currently has no plan | | `NotConfirmed` | The user has not confirmed their email address | | `NotActive` | The user is not active (subscription has expired) | | `OptionNotAvailableOnPlan` | The feature is not available on the user's plan | | `InvalidOptions` | The options supplied were invalid | | `InvalidTtl` | The TTL supplied was invalid | | `NoS3BucketConfigured` | The user has not configured an S3 bucket for their project | | `RateLimitExceededError` | The user's rate limit has been exceeded | | `TrialUsageReached` | The user's trial usage has been reached | | `HTMLProcessError` | The HTML could not be processed | | `InvalidQuery` | The query string was invalid | | `NoUrlSupplied` | No URL was supplied in the request | | `UrlWasNotAStringError` | The URL supplied was not a string | | `InvalidURLExtensionError` | The URL extension was invalid | | `InvalidURLError` | The URL was invalid | | `URLDoesNotResolveError` | The URL does not resolve to a valid IP address | | `RenderTimeoutError` | The render timed out before it could be completed | | `TokenlessRequestsNotEnabled` | The user has not enabled tokenless (basic render link) requests | | `NoQuerySent` | No query was sent in the request | | `TokenNotMatchedError` | The token supplied did not match the token for the query string | | `EngineResponseNotOkError` | The rendering engine was not able to generate the render | | `EngineAsyncResponseNotOkError` | The rendering engine was not able to generate the render (async) | | `TimedOutError` | The request timed out | | `NoRenderIdProvided` | No render ID was provided (when looking up a render) | | `ApiKeyWrongFormat` | The API key was not sent in the correct format | ## Endpoints A render is our generic term for anything that can be generated by the API, for example a screenshot is a render, a pdf is a render, so too is a video. You can create all kinds of render using the same endpoint, by specifying the options relevant to that render kind. ## Create a render synchronously Creating a render synchronously is achieved by calling this endpoint. Send a POST to `/v1/render/sync` and pass in the [render options](https://urlbox.com/docs/options.md) you want to use. The endpoint accepts either JSON or form-encoded data. The only required option is either `url` or `html`. When using `url`, the URL must be publicly accessible. This endpoint responds with `200 OK` once the render has been generated. The response body will contain a `renderUrl` key which is a temporary URL pointing to the generated render. This `renderUrl` will expire after 30 days. The `size` key contains the size of the render in bytes. #### Long running requests After 95 seconds, if the render has not yet been generated, the API will return a `307 Temporary Redirect` response with a `Location` header set to a temporary redirect URL. This is to prevent request timeouts from cloudflare interrupting the request early. When this URL is followed the request will continue to wait for the render to be returned. The response body will contain a `redirectUrl` key also with the same temporary redirect URL. The redirect timeout can be configured using the `redirect_after` option. #### Caching Requests to this endpoint are *not* cached, and not de-duplicated. If you make the same request twice, that will count as two renders. #### Options To see a full list of options that can be supplied, see the [options reference](https://urlbox.com/docs/options.md). Options can be supplied in camelCase or snake\_case. | Name | Type | Description | | --------------------- | --------- | -------------------------------------------------------------------------------------------- | | `url` | `string` | The URL to render | | `html` | `string` | The HTML to render | | `format` | `string` | The output format of the render. One of `png`, `jpg`,`webp`, `pdf`, `svg`, `mp4`,`webm`,`md` | | `width` | `integer` | The width of the viewport in pixels | | `height` | `integer` | The height of the viewport in pixels | | `full_page` | `boolean` | Whether to render the full page or just the viewport | | `selector` | `string` | Screenshot just the element specified by the selector | | `hide_cookie_banners` | `boolean` | Whether to hide cookie banners | | `click_accept` | `boolean` | Whether to click the accept button on cookie banners | | `block_ads` | `boolean` | Whether to block ads | ```zsh POST /v1/render/sync ``` ```json { "url": "https://urlbox.com", "format": "png", "width": 1280, "height": 720 } ``` ```json { "renderUrl": "https://renders.urlbox.com/urlbox1/renders/646625c282754962161b5cb3/2023/9/25/eee820e7-0d85-46af-94ff-1f6160664f3a.png", "size": 310517, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299 } ``` ## Create a render asynchronously Creating a render asynchronously is achieved by calling this endpoint. Send a POST to `/v1/render/async` and pass in the [render options](https://urlbox.com/docs/options.md) you want to use. The endpoint accepts either `application/json` or `application/x-www-urlencoded` payloads. The only required option is either `url` or `html`. When using `url`, the URL must be publicly accessible. #### Response This endpoint responds immediately with HTTP status code `201 Created` once a render request has been successfully accepted. The response body will contain a `status` which will be set to `created` to show that the render request has been accepted and is being processed, and a `renderId` which is the ID of the render. The response body will also contain a `statusUrl` which allows you to [poll the current status of the render](#check-the-status-of-a-render). An alternative to polling is to [use webhooks](https://urlbox.com/docs/webhooks.md). ##### Error Response If the render request is rejected, the endpoint will respond with a `400 Bad Request` status code, with an error object in the response body for example: ```http HTTP/1.1 400 Bad Request Content-Type: application/json { "error": { "message": "Invalid URL", "code": "InvalidURLError" }, "requestId": "0198613b-e03c-702c-892b-ef21eaaef4a7_pa" } ``` #### Caching Requests to this endpoint are *not* cached, and not de-duplicated. If you make the same request twice, that will count as two renders. #### Options To see a full list of options that can be supplied, see the [options reference](https://urlbox.com/docs/options.md). ```zsh POST /v1/render/async ``` POST /v1/render/async ```json { "url": "https://urlbox.com", "format": "png", "width": 1280, "height": 720 } ``` ```json { "status": "created", "renderId": "250ea007-552c-4555-ba2b-ef1c73e18be2", "statusUrl": "https://api.urlbox.com/v1/render/250ea007-552c-4555-ba2b-ef1c73e18be2" } ``` ## Check the status of a render You can check the status of a render by calling this endpoint. Send a GET request to `/v1/render/:renderId` and replace the path variable `:renderId` with the ID of the render you want to check. This is returned to you when you [create a render asynchronously](#create-a-render-asynchronously). #### Response This endpoint responds immediately with HTTP status code `200 OK` if a render request has been successfully accepted, or if the render has already been generated. The response body will contain a `renderId` key which is the ID of the render, and a `statusUrl` key which allows you to poll the current status of the render. The response body will also contain a `status` key which will be one of the following values: - `created` - The render has been created and is being processed - `retrying` - The render has stalled and is being retried - `succeeded` - The render has been successfully generated - `failed` - The render has failed to be generated - `not-found` - The render was not found In the case of a succeeded render, the response body will contain a `renderUrl` key which will contain the URL of the generated render, and a `size` key which will contain the size of the render in bytes. In the case of a failed render, the response body will contain a `reason` key which will contain a human readable message explaining why the render failed. If a renderId is not found, the endpoint will respond with a `404 Not Found` status code, and `status` set to `not-found`. ```zsh GET /v1/render/:renderId ``` GET /v1/render/250ea007-552c-4555-ba2b-ef1c73e18be2 ```json ``` ```http HTTP/1.1 200 OK Content-Type: application/json { "renderId": "250ea007-552c-4555-ba2b-ef1c73e18be2", "status": "succeeded", "renderUrl": "https://renders.urlbox.com/urlbox1/renders/571f54138cd8b877077d3788/2023/9/25/250ea007-552c-4555-ba2b-ef1c73e18be2.png", "size": 781026, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299 } ``` --- # Authenticated Requests > Learn how to send authenticated requests Source: https://urlbox.com/docs/authenticated-requests Last updated: 2026-07-31 --- Since your API key is embedded in the `GET` URL format, this means that if your Urlbox URLs are used publicly, anyone could potentially start using your API key to make requests against the Urlbox API - and use up your quota. To prevent anonymous usage, you can use the authenticated request format, which is shown below: [https://api.urlbox.com/v1/api-key/auth-token/format?options](https://api.urlbox.com/v1/api-key/auth-token/format?options) Where: - api-key is replaced by your Urlbox API key, which you can get by [registering](https://urlbox.com/signup.md) for an account - auth-token is replaced by a hash, which is generated server side by taking the `HMAC SHA256` of the query string and signing it with your API secret - format is one of: - `png` - `jpg` or `jpeg` - `avif` - `webp` - `pdf` - `svg` - `html` - options is replaced by a query string that contains all of the options you want to set - for example: - `url=example.com&full_page=true&width=300` ## Generating the auth token No matter which language you are using, they will all have a method to generate a hmac-sha256 hash. We have code samples for the most popular languages available [here](./examplecode/node). A simple way to check that you have generated the correct token is to open your terminal and run the following command: ```zsh echo -n | openssl sha256 -hmac "" ``` Let's say we want to take a screenshot of urlbox.com and set the width option to 300px. In order to generate the token, we take the query string, which is url=urlbox.com\&width=300, and create the auth token by using our secret key to sign a hmac-sha256 hash of it: ```zsh echo -n "url=urlbox.com&width=300" | openssl sha256 -hmac "my_secret_key" $> a6f5fb4b61eaba63a4546b87c14091c9ca3fbe73 ``` We then insert this token into the url path to create our authenticated URL: [https://api.urlbox.com/v1/api-key/a6f5fb4b61eaba63a4546b87c14091c9ca3fbe73/png?url=urlbox.com\&width=300](https://api.urlbox.com/v1/api-key/a6f5fb4b61eaba63a4546b87c14091c9ca3fbe73/png?url=urlbox.com\&width=300) Because the token is a hash of the query string, whenever you change your query string, you will need to ensure that the token matches, otherwise you will get an unauthenticated error response from the API. ## Forcing authenticated requests By default, unauthenticated requests are allowed when you first sign up, but you should switch over to authenticated requests as soon as you have gotten familiar with the API and it's options. By default, unauthenticated requests are allowed when you first sign up, but you should switch over to authenticated requests as soon as you have gotten familiar with the API and its options. Now, if you try to make a request to the urlbox API without an auth token: ``` GET https://api.urlbox.com/v1/api-key/png?url=urlbox.com ``` you will receive the following response: ```zsh HTTP/2 400 Bad Request Content-Type: application/json X-Urlbox-Error-Message: Please enable tokenless requests in the dashboard or pass a valid auth token { "error": { "message": "Please enable tokenless requests in the dashboard or pass a valid auth token", "code": "TokenlessRequestsNotEnabled" } } ``` --- # Quick Start > Quickly learn how to use Urlbox's rendering API Source: https://urlbox.com/docs/getting-started Last updated: 2026-07-31 --- Thank you for checking out Urlbox. This guide will cover the basics to start rendering quickly. ## Prerequisites - Get your API key and secret key from the [dashboard](https://urlbox.com/dashboard.md). - If you don't have an account, [sign up](https://urlbox.com/signup.md) for a 7-day free trial. ## Making your first request 1. Create a basic render link using your api key and desired output format: [https://api.urlbox.com/v1/api-key/format?url=example.com](https://api.urlbox.com/v1/api-key/format?url=example.com) 2. Modify the options query string to fit your rendering preferences. All rendering options are decribed in detail in the [render options](https://urlbox.com/docs/options.md) reference page. ### Example Render a thumbnail screenshot of github.com, taken from a mobile viewport. Set the format to `png` and the [`url`](https://urlbox.com/docs/options.md#url) to github.com, with a viewport [`width`](https://urlbox.com/docs/options.md#width) of 390px and [`height`](https://urlbox.com/docs/options.md#height) of 844px to mimic a mobile device. Additionally, set [`thumb_width`](https://urlbox.com/docs/options.md#thumb_width) to 200 to resize the image to 200 pixels wide. The render link will look like this: [https://api.urlbox.com/v1/api-key/png?url=github.com\&width=390\&height=844\&thumb\_width=200](https://api.urlbox.com/v1/api-key/png?url=github.com\&width=390\&height=844\&thumb_width=200) Now open that up in a new tab, and you should see something like this: ## Secure your links For production use, you'll want to use secure render links to ensure only authorized users can render screenshots on your account: [https://api.urlbox.com/v1/api-key/token/format?url=example.com](https://api.urlbox.com/v1/api-key/token/format?url=example.com) The token is a HMAC-SHA256 token of the query string options signed by your **secret** key ### Example with Authentication Let's take the previous example, and add authentication to it. Create the token from the query string in javascript (we have [example code](https://urlbox.com/docs/examplecode.md) to do this for other languages too): ```js import hmacSha256 from "crypto-js/hmac-sha256"; const secretKey = "your-secret-key"; const options = "url=github.com&width=390&height=844&thumb_width=200"; const token = hmacSha256(options, secretKey).toString(); ``` Insert the token into the render link: [https://api.urlbox.com/v1/api-key/token/png?url=github.com\&width=390\&height=844\&thumb\_width=200](https://api.urlbox.com/v1/api-key/token/png?url=github.com\&width=390\&height=844\&thumb_width=200) This is now a secure render link. If somebody was to come along and try to change any of the options, to create a different render, the token would no longer be valid, and the request would be rejected. The only way for someone to generate a valid token is to know your secret key, which is why you should try to keep it secret. ## Using the JSON API Urlbox also offers a JSON-based [REST API](https://urlbox.com/docs/api.md) for synchronous and asynchronous rendering. The API uses Bearer token authentication, with your secret key as the token. Insert it in the Authorization request header: `Authorization: Bearer YOUR_URLBOX_SECRET`. ### Example using JSON API To use the same example with the JSON API, `POST` the options as JSON to the `/v1/render/sync` endpoint. ```json { "url": "github.com", "width": 390, "height": 844, "thumb_width": 200, "format": "png" } ``` and we'll get back a response like this: ```http HTTP/1.1 200 OK Content-Type: application/json --- { renderUrl: "https://renders.urlbox.com/urlbox1/renders/646625c2884762962161b5cb3/2042/9/29/a21872ec-9a65-4b7b-9e30-ede0ebb2627a.png", size: 208578, renderTime: 6609, queueTime: 127, bandwidth: 9429299 } ``` - The `renderUrl` is temporary and will expire after 30 days. To keep the image, you'll need to download it, or tell Urlbox to [save it to your cloud bucket](https://urlbox.com/docs/guides/s3.md). - To render asynchronously, switch to using the `/v1/render/async` endpoint. More details can be found in the [API documentation](https://urlbox.com/docs/api.md). Whilst render links give you the convenience of rendering directly from an `` tag, the JSON API gives more flexibility and is more suited for rendering from HTML. Read more about the differences [here](https://urlbox.com/docs/.md). --- # Overview > Welcome to Urlbox, an API for converting URLs and HTML into screenshots, PDFs, videos, and extracting text, html and metadata with ease. Source: https://urlbox.com/docs Last updated: 2026-07-31 --- Learn how to capture your first render ## Learn More Complete endpoint documentation with parameters, responses, and authentication details. Ready-to-use code examples in Python, Node.js, PHP, and more to get you screenshotting fast. Step-by-step tutorials for common use cases like batch processing and webhook integration. Customize screenshots with viewport sizes, formats, delays, selectors, and advanced settings. ## How it works In general, there are two ways to call the API: 1. Using [render links](https://urlbox.com/docs/render-links.md) which can be embedded directly into image tags, and returns the render directly. 2. POST to the [JSON API](https://urlbox.com/docs/api.md) asynchronously or synchronously. ## Use Cases Urlbox has many different use cases, spanning several industries. Below are a few examples of what you can do with Urlbox: ### Screenshots from URL - Build a website inspiration gallery - Create assets / artifacts for advertising networks in various dimensions - Repeatedly screenshot and keep an archive of websites to ensure that they are not using your brand's IP - Take hourly screenshots of various news websites for achival or legal purposes - Add 'export to PNG' functionality to your website - Preview different headlines / copy on your clients' websites - Generate thumbnail screenshots - Run a 'sanity check' screenshot to check that your site looks good at different viewport sizes before releasing ### Screenshots from HTML - Save an image of dynamic user-generated content - Generate open graph images by embedding the Urlbox render link directly in meta tags - Add an 'export to PDF' function to your website ### PDF's - Generate PDF invoices from a URL or HTML - Generate PDF catalogues of social media influencers, PR campaigns, etc. ### Video - Generate video previews of websites - Capture scroll linked animations using scrolling video capture ### Metadata - Extract metadata and markdown from a URL - Extract custom metadata from a URL ### HTML - Grab the HTML source code from a URL ### No-Code - Render website thumbnails from a list of URLs stored in CSV's, Google Sheets or Airtable - Schedule and compare screenshots over different time frames - Screenshot and archive Google search results for various search queries - and many more! --- # Render Options > Detailing all available render options for Urlbox's rendering API Source: https://urlbox.com/docs/options Last updated: 2026-07-31 --- ## Basic Options Basic options for rendering such as setting the URL or HTML, and viewport width and height ### `url` The URL or domain of the website you want to screenshot. We will automatically prepend `http://` if it is missing. #### `url` Examples *** ### `html` The HTML you want to render. #### `html` Examples *** ### `format` The output format of the resulting render. The available values are: `png` `jpeg` `webp` `avif` `svg` `pdf` `html` `mp4` `webm` `md` #### `format` Examples *** ### `width` default: `1280` The viewport width of the browser, in pixels. #### `width` Examples *** ### `height` default: `1024` The viewport height of the browser, in pixels. #### `height` Examples *** ### `full_page` default: `false` Specify whether to capture the full scrollable area of the website. For PDFs, `full_page` mode will attempt to capture the whole website onto one single page PDF document. It's likely you'll want to also hide any cookie banners that crop up during a full page screenshot, so we recommend you use [`click_accept`](#click_accept) and [`hide_cookie_banners`](#hide_cookie_banners) too. #### `full_page` Examples *** ### `full_page_slices` default: `false` Split the full page screenshot into smaller vertical slices, each stored as its own image. The JSON response includes a `slices` array containing the `url`, `offset_y`, `width` and `height` of every slice. Very tall screenshots are often downscaled or rejected by AI vision models, so sending smaller slices one at a time usually produces better analysis results. Requires [`full_page`](#full_page) to be `true`. Control the size of each slice with [`full_page_slice_height`](#full_page_slice_height) and [`full_page_slice_overlap_height`](#full_page_slice_overlap_height). #### `full_page_slices` Example *** ### `full_page_slice_height` default: `4000` The maximum height in pixels of each slice when [`full_page_slices`](#full_page_slices) is enabled. Must be between `1` and `16000`. If the full page screenshot is shorter than this value, a single slice is returned. #### `full_page_slice_height` Examples *** ### `full_page_slice_overlap_height` default: `0` The number of pixels of vertical overlap between adjacent slices when [`full_page_slices`](#full_page_slices) is enabled. Overlap means content cut at a slice boundary appears in full in at least one slice, which helps when analysing slices independently. The [`full_page_slice_height`](#full_page_slice_height) minus the overlap must be at least `100`. #### `full_page_slice_overlap_height` Examples *** ### `selector` Take a screenshot of the element that matches this selector. By default, if the selector is not found, Urlbox will take a normal viewport screenshot. If you prefer Urlbox to fail the request when the selector is not found, pass `fail_if_selector_missing=true`. #### `selector` Examples *** ### `clip` Clip the screenshot to the bounding box specified by `x,y,width,height`. #### `clip` Examples *** ### `gpu` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above default: `false` Enable GPU acceleration to render 3D scenes and heavy WebGL content. This is a beta feature and requires pre-approval. Please contact [support@urlbox.com](mailto:support@urlbox.com) to enable this feature on your account. #### `gpu` Examples *** ### `response_type` For render link requests, setting this option to `json` will change the response type of the Urlbox request to JSON. For the API, the default response type is JSON. The available values are: `json` `binary` #### `response_type` Examples *** ### `secure_mode` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above Enforces zero data retention through secure mode to ensure sensitive data remains protected throughout the rendering process. All request data is automatically purged within 90 seconds of the render completing. In addition to this option, you need to use one of the storage approaches described in our [Secure Screenshots guide](https://urlbox.com/secure-screenshots.md). *** ## Blocking Options Options for blocking or dismissing certain page elements, such as cookie banners. ### `block_ads` Blocks requests from popular advertising networks from loading. #### `block_ads` Examples *** ### `hide_cookie_banners` Automatically hides cookie banners from most websites, by setting their style to `display: none !important;` #### `hide_cookie_banners` Examples *** ### `click_accept` Similar to the [`hide_cookie_banners`](#hide_cookie_banners) option, but instead of hiding the banners, this option attempts to click on the 'Accept' button, in order to accept cookies. #### `click_accept` Examples *** ### `press_escape` Attempts to press the Escape (ESC) key before capturing the page. Useful for dismissing pop-ups, overlays, or advertising banners that appear on load. *** ### `block_urls` Block requests from specific domains from loading. You can use wildcard characters such as `*` to match subdomains. #### `block_urls` Examples *** ### `block_images` Blocks image requests #### `block_images` Example *** ### `block_fonts` Blocks font requests #### `block_fonts` Examples *** ### `block_medias` Block video and audio requests #### `block_medias` Examples *** ### `block_styles` Prevent stylesheet requests from loading #### `block_styles` Examples *** ### `block_scripts` Prevent requests for javascript scripts from loading #### `block_scripts` Examples *** ### `block_frames` Prevents iframe and frame content from loading by blocking non-navigation document requests. The main page will load normally, but any embedded frames/iframes will be blocked. #### `block_frames` Example *** ### `block_fetch` Block fetch requests from the target URL. *** ### `block_xhr` Block XHR requests from the target URL. #### `block_xhr` Example *** ### `block_sockets` Prevents WebSocket connections from being established, blocking real-time communication features like live chat, notifications, or dynamic updates. *** ### `block_data_urls` Block data URLs such as `data:image/png;base64,...` *** ### `hide_selector` Hide specific HTML elements on the page before rendering. This option accepts a comma-delimited string of CSS element selectors that will be hidden by setting their style to `visibility: hidden !important; pointer-events: none !important;`. This preserves the page layout while making elements invisible. This is particularly useful for: - Hiding pop-ups, banners, or cookie notices - Removing advertisements or promotional overlays - Excluding navigation menus or sidebars - Hiding specific content sections **Selector types supported:** - **Element selectors** (e.g., `h1`, `div`, `img`) - Hide all elements of that type - **Class selectors** (e.g., `.popup`, `.banner`) - Hide elements with specific CSS classes - **ID selectors** (e.g., `#header`, `#sidebar`) - Hide elements with specific IDs - **Complex selectors** (e.g., `.nav ul li`, `div.content > p`) - Use any valid CSS selector - **Multiple selectors** - Combine multiple selectors with commas **Tip:** To find the selector for any element, open your browser's DevTools, right-click the element in the Elements tab, and select "Copy > Copy selector". #### `hide_selector` Examples *** ## Customize Options Customize the look of the page before rendering a screenshot ### `js` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above Execute custom JavaScript in the context of the page. The JS gets executed after the page's dom has loaded, but before the screenshot is taken. No need to use `load` etc event handlers to run code, as these events will already have fired by the time this JS gets executed. You can use `await` to wait for promises to resolve. #### `js` Examples *** ### `css` Inject custom CSS into the page #### `css` Examples *** ### `dark_mode` default: `false` Emulate dark mode on websites by setting `prefers-color-scheme: dark` #### `dark_mode` Examples *** ### `reduced_motion` Prefer less animations on websites by setting `prefers-reduced-motion: reduced` #### `reduced_motion` Examples *** ### `show_timestamp` Shows a timestamp in a header above the rendered screenshot. Can be paired with show URL. If you're rendering a PDF, you can achieve this with the show\_header option. #### `show_timestamp` Examples *** ### `show_url` Shows a URL in a header above the rendered screenshot. Can be paired with show timestamp. If you're rendering a PDF, you can achieve this with the show\_header option. #### `show_url` Examples *** ## Screenshot Options Options relating to the generated screenshot image ### `retina` default: `false` Take a 'retina' or high-definition screenshot, equivalent to setting a device pixel ratio of 2.0 or @2x. Please note that retina screenshots will be double the normal dimensions and will normally take slightly longer to process due to the much bigger image size. #### `retina` Examples *** ### `thumb_width` The width of the generated thumbnail, in pixels. Omit for a full-size screenshot. For generating one or more separate thumbnail files alongside the full-size render (rather than resizing the main image), use the [`thumbnails`](#thumbnails) option instead. #### `thumb_width` Examples *** ### `thumb_height` The height of the generated thumbnail, in pixels. Omit for a full-size screenshot. For generating one or more separate thumbnail files alongside the full-size render (rather than resizing the main image), use the [`thumbnails`](#thumbnails) option instead. #### `thumb_height` Examples *** ### `img_fit` default: `cover` How the screenshot should be resized or cropped to fit the dimensions when using [`thumb_width`](#thumb_width) and/or [`thumb_height`](#thumb_height) options The available values are: - **cover** - Preserving aspect ratio, attempt to ensure the image covers both `thumb_width` and/or `thumb_height` by cropping/clipping to fit. - **contain** - Preserving aspect ratio, contain within both `thumb_width` and/or `thumb_height` using letterboxing where necessary. - **fill** - Ignore the aspect ratio and stretch to both `thumb_width` and/or `thumb_height`. - **inside** - Preserving aspect ratio, resize the image to be as large as possible while ensuring its dimensions are less than or equal to `thumb_width` and/or `thumb_height`. - **outside** - Preserving aspect ratio, resize the image to be as small as possible while ensuring its dimensions are greater than or equal to `thumb_width` and/or `thumb_height`. #### `img_fit` Examples *** ### `img_position` default: `center` How the image should be positioned when using an [`img_fit`](#img_fit) of `cover` or `contain`. The available values are: `north` `northeast` `east` `southeast` `south` `southwest` `west` `northwest` `center` `centre` #### `img_position` Examples *** ### `img_bg` Background colour to use when [img\_fit](#img_fit) is `contain`, or [`img_pad`](#img_pad) is used, defaults to black without transparency #### `img_bg` Examples *** ### `img_pad` Pad the screenshot, giving it a border. Can either be a single pixel value that gets added to each side, or a comma delimited string of `top,right,bottom,left` pixel values. #### `img_pad` Examples *** ### `quality` default: `80` The image quality of the resulting screenshot (JPEG/WebP only) #### `quality` Examples *** ### `transparent` default: `false` If a website has no background color set, the image will have a transparent background (PNG/WebP only) *** ### `max_height` For extremely lengthy websites, it may be preferable to limit the screenshot to a maximum height to prevent Urlbox from spending time scrolling and generating an enormous screenshot. #### `max_height` Example *** ### `download` Pass in a filename which sets the content-disposition header on the response. E.g. `download=myfilename.png` This will make the Urlbox link downloadable, and will prompt the user to save the file as `myfilename.png` #### `download` Example *** ## Thumbnail Options Options relating to generating thumbnails of the main screenshot. Each spec's `fit`, `bg` and `position` fall back to the [`img_fit`](#img_fit), [`img_bg`](#img_bg) and [`img_position`](#img_position) options in Screenshot Options, which also serve the legacy [`thumb_width`](#thumb_width)/[`thumb_height`](#thumb_height) single-resize. ### `thumbnails` Generate up to 5 additional thumbnail images from the same render, each uploaded as its own file alongside the main screenshot. `thumbnails` is independent of the main screenshot's own dimensions, and unrelated to the legacy [`thumb_width`](#thumb_width)/[`thumb_height`](#thumb_height) options above, which resize the primary screenshot itself. Each entry in the array is an object with the following keys, all optional: - **key** - A short identifier (max 10 characters) for this thumbnail. Used as its filename suffix, and as its key in the JSON response (or in [`thumbnails_object`](#thumbnails_object)'s object response). - **preset** - One of `xs`, `sm`, `md`, `lg`, `xl`, `2xl`, `3xl`, `4xl`, `5xl`, `1/2`, `1/4`, `3/4`. Scales the thumbnail as a percentage of the original screenshot's dimensions (e.g. `md` is 30%, `1/2` is 50%). Takes priority over `size`/`width`/`height` when set. - **size** - A single pixel value (`10`-`2000`), used as both the width and the height. - **width** - The thumbnail width in pixels (`10`-`2000`). - **height** - The thumbnail height in pixels (`10`-`2000`). - **fit** - How the thumbnail should be resized or cropped to fit its dimensions: `cover`, `contain`, `fill`, `inside` or `outside`. Falls back to the top-level [`img_fit`](#img_fit) option, then `cover`. - **bg** - Background color used for letterboxing. Falls back to the top-level [`img_bg`](#img_bg) option, then [`bg_color`](#bg_color), then `black`. - **position** - How the image should be positioned within its `fit`. Any [`img_position`](#img_position) value, including `attention` and `entropy`, which crop around the most visually interesting or highest-entropy region of the image. Falls back to the top-level `img_position` option, then `north`. - **suffix** - A custom filename suffix, used when `key` isn't set. - **presigned\_url** - A presigned URL to upload this specific thumbnail to, instead of Urlbox's own storage. `thumbnails` can be supplied as a JSON array in a POST body: ```json "thumbnails": [{ "preset": "md" }, { "width": 320, "key": "w320" }] ``` or, over a GET/query-string request, using `qs`-style bracket notation: ``` &thumbnails[0][preset]=md&thumbnails[1][width]=320&thumbnails[1][key]=w320 ``` Each generated thumbnail appears in the JSON response (see [`response_type`](#response_type)) as an entry in a `thumbnails` array, each with a `key`, `location` and `size` - or, when [`thumbnails_object`](#thumbnails_object) is `true`, as an object keyed by that `key`/suffix instead of an array. #### `thumbnails` Example *** ### `thumbnails_object` default: `false` Reshapes the [`thumbnails`](#thumbnails) response from an array into an object keyed by each thumbnail's `key`/suffix, with `key` omitted from each value (since it's now the object's own key). Useful for looking up a specific thumbnail directly instead of scanning the array. For example, with `thumbnails: [{ preset: "md", key: "w320" }]`, the default array response is: ```json "thumbnails": [{ "key": "w320", "location": "...", "size": 12345 }] ``` and with `thumbnails_object: true`, it becomes: ```json "thumbnails": { "w320": { "location": "...", "size": 12345 } } ``` Has no effect unless [`thumbnails`](#thumbnails) is also set. #### `thumbnails_object` Examples *** ## PDF Options Options relating to PDF document generation. ### `pdf_page_size` default: `A4` Sets the PDF page size. Setting this option will take precedence over `pdf_page_width` and `pdf_page_height`. The available values are: `A0` `A1` `A2` `A3` `A4` `A5` `A6` `Legal` `Letter` `Ledger` `Tabloid` #### `pdf_page_size` Examples *** ### `pdf_page_range` Sets the PDF page range to return. By default, the page is split into a multi page document and returns all page. Use this option to restrict which pages should be returned. #### `pdf_page_range` Examples *** ### `pdf_page_width` Sets the PDF page width, in pixels. #### `pdf_page_width` Examples *** ### `pdf_page_height` Sets the PDF page height, in pixels. #### `pdf_page_height` Examples *** ### `pdf_margin` default: `none` Sets the margin of the PDF document. The available values are: `none` `default` `minimum` #### `pdf_margin` Examples *** ### `pdf_margin_top` Sets a custom top margin on the PDF. #### `pdf_margin_top` Example *** ### `pdf_margin_right` Sets a custom right margin on the PDF. #### `pdf_margin_right` Example *** ### `pdf_margin_bottom` Sets a custom bottom margin on the PDF. #### `pdf_margin_bottom` Example *** ### `pdf_margin_left` Set a custom left margin on the PDF. #### `pdf_margin_left` Example *** ### `pdf_auto_crop` Automatically remove white space from PDF. Occasionally a PDF will have a lot of trailing white space at the bottom of the page. This option will attempt to automatically crop the PDF to remove this white space. *** ### `pdf_scale` default: `1` Sets the scale factor of the website content in the PDF. Valid values are numbers between 0.1 and 2. #### `pdf_scale` Examples *** ### `pdf_orientation` default: `portrait` Sets the orientation of the PDF. The available values are: `portrait` `landscape` #### `pdf_orientation` Examples *** ### `pdf_background` default: `true` Sets whether to print background images in the PDF #### `pdf_background` Examples *** ### `disable_ligatures` Prevents ligatures from being used. Useful when rendering a PDF, and you want to extract text which contains ligatures. *** ### `media` By default, when generating a PDF, the `print` CSS media query is used. To generate a PDF using the `screen` CSS, set this option to `screen`. When generating an image, the `screen` CSS media query is used by default. To generate an image using the `print` CSS, set this option to `print`. #### `media` Examples *** ### `pdf_show_header` Whether to show the default pdf header on each page of the pdf. The template of the header can be changed by setting the [`pdf_header`](#pdf_header) option. #### `pdf_show_header` Example *** ### `pdf_header` Change the default pdf header that is shown on each page of the pdf when [`pdf_show_header`](#pdf_show_header) option is set. You have the option to show the following variables in the header (or footer) of the pdf: - current `date` - `title` of the page - `url` of the page - current `pageNumber` - the `totalPages` in the pdf document You can display these variables by creating empty divs or spans, with special css class names relating to the variable you want to show. For example, if you want to show the `date` followed by the `url`, you could use the following pdf header template: `
`. The pdf header template you set are inserted as the innerHTML of a parent div which is a flex container, and has `align-items` set to `flex-start`. There are also some helper classes for aligning the divs or spans. The following classes are available: - `left` - adds some left padding to the element and sets `flex: none`. - `center` - aligns the element and text to the center. - `right` - adds some right padding to the element and sets `flex: none`. - `text` - sets the text to 8pt. - `grow` - sets `flex: auto` on the element, allowing it to grow to fill the available space. The default pdf header is: `
`. You can see exactly how the pdf page is constructed by looking at the [chromium pdf template](https://source.chromium.org/chromium/chromium/src/+/main:components/printing/resources/print_header_footer_template_page.html;l=98-100?q=header_footer%20\&ss=chromium%2Fchromium%2Fsrc) in the chromium source repository. #### `pdf_header` Examples *** ### `pdf_show_footer` Whether to show the default pdf footer on each page of the pdf. The template of the footer can be changed by setting the [`pdf_footer`](#pdf_footer) option. #### `pdf_show_footer` Example *** ### `pdf_footer` Change the default pdf footer that is shown on each page of the pdf when [`pdf_show_footer`](#pdf_show_footer) option is set. You have the option to show the following variables in the footer (or header) of the pdf: - current `date` - `title` of the page - `url` of the page - current `pageNumber` - the `totalPages` in the pdf document You can display these variables by creating empty divs or spans, with special css class names relating to the variable you want to show. For example, if you want to show the `date` followed by the `url`, you could use the following pdf footer template: `

There are also some helper classes for aligning the divs or spans. The following classes are available: - `left` - adds some left padding to the element and sets `flex: none`. - `center` - aligns the element and text to the center. - `right` - adds some right padding to the element and sets `flex: none`. - `text` - sets the text to 8pt. - `grow` - sets `flex: auto` on the element, allowing it to grow to fill the available space. The default pdf footer is: `

You can see exactly how the pdf page is constructed by looking at the [chromium pdf template](https://source.chromium.org/chromium/chromium/src/+/main:components/printing/resources/print_header_footer_template_page.html;l=101-105?q=header_footer%20\&ss=chromium%2Fchromium%2Fsrc) in the chromium source repository. #### `pdf_footer` Examples *** ### `readable` Make the pdf into a readable document by removing unnecessary elements such as navigation bars, ads, etc. #### `readable` Example *** ### `pdf_title` Sets the title metadata field of the PDF document. This is visible in PDF readers under document properties. If not set, the page's `` tag will be used as the PDF title. *** ### `pdf_subject` Sets the subject metadata field of the PDF document. This is visible in PDF readers under document properties. *** ### `pdf_author` Sets the author metadata field of the PDF document. This is visible in PDF readers under document properties. *** ### `pdf_keywords` Sets the keywords metadata field of the PDF document. Pass a comma-separated list of keywords, e.g. `"pdf_keywords": "screenshot,web,api"`. This is visible in PDF readers under document properties and can help with document organization and search. *** ### `pdf_creator` Sets the creator metadata field of the PDF document. This typically indicates the application that created the original content. Visible in PDF readers under document properties. *** ## Video Options Options for rendering MP4 or WebM videos of a website. Set `format` to `mp4` or `webm` to record a video instead of taking a screenshot. Pair these with the Video Scrolling Options below to control what the video shows. ### `video_time` default: `3000` How long to record for, in milliseconds. When scrolling is enabled the scroll choreography runs within this time; without scrolling the recording simply lasts this long. `video_duration` is an alias that takes seconds instead of milliseconds. When using `video_scroll_to`, the video length is derived from your sections automatically and `video_time` caps the scroll choreography (the section scrolls and waits, with lead-in, scroll-back and tail riding on top). #### `video_time` Example *** ### `video_fps` default: `60` Frames per second to record at. Higher values give smoother scrolling at the cost of larger files and slightly longer render times. #### `video_fps` Example *** ### `video_width` default: `1280` Width of the output video in pixels. The page is rendered at the usual viewport size (`width`/`height`) and the recording is scaled to `video_width` x `video_height`. *** ### `video_height` default: `1024` Height of the output video in pixels. #### `video_height` Example *** ### `video_quality` default: `23` Constant rate factor for the H.264 encoder. Lower is higher quality and larger files. Typical values are 18 (visually lossless) to 28. *** ### `video_preset` default: `medium` Encoder speed/compression trade-off. Slower presets compress better (smaller files at the same quality) but take longer to encode. The available values are: `ultrafast` `superfast` `veryfast` `faster` `fast` `medium` `slow` `slower` `veryslow` #### `video_preset` Example *** ### `video_bitrate` Target bitrate for the recording, in kbps. An alternative to `video_quality` when you need to hit a specific file-size budget. *** ### `video_codec` default: `h264` Video codec for the output. `h264` produces MP4s with the widest playback support; `vp9`/`vp8` produce WebM. Setting `format` to `webm` selects a WebM codec automatically. The available values are: `h264` `vp9` `vp8` #### `video_codec` Example *** ## Video Scrolling Options Options controlling how the page is scrolled while a video records. Enable a simple top-to-bottom scroll with `video_scroll`, or choreograph stops at specific sections with `video_scroll_to`. ### `video_scroll` default: `false` Smoothly scroll down the page while recording, section by section, then scroll back to the top. Scroll speed, easing, pauses and distance are controlled by the options below. #### `video_scroll` Example *** ### `video_scroll_to` Scroll to specific sections of the page in turn, pausing at each for a set time, for example to walk through key features or synchronise a scroll with a voiceover. Each entry is a CSS selector (automatically piercing open shadow DOM, however deeply nested) or a `text=` locator matching visible text, plus optional per-section settings: `wait` (pause at the section), `duration` (how long the scroll to it takes), `ease` (easing name, lower-case, see `video_ease`), and `offset` (stop N pixels above the element, useful under sticky headers). In a render link, repeat the parameter once per section using `;key=value` modifiers, e.g. `video_scroll_to=%23reviews;wait=4s`. In a JSON body, pass an array of the same strings or of objects. Durations accept milliseconds (`2500`) or unit strings (`"2.5s"`, `"500ms"`). The video's length is derived from your sections (capped at 400s; an explicit `video_time` truncates). If a section isn't found, its full time slot still elapses at the current position so the rest of the timeline stays in sync. A literal `;` inside a `text=` value needs the JSON object form. `video_scroll_offset` sets the default `offset` used for every section that doesn't specify its own. #### `video_scroll_to` Examples *** ### `video_scroll_require_sections` default: `false` Fail the render with a 400 error if any `video_scroll_to` section can't be found on the page, instead of holding position through its time slot. Use this when a wrong video is worse than no video. *** ### `video_scroll_offset` default: `0` Global default viewport offset for `video_scroll_to` stops, in pixels. Positive values stop the scroll with the viewport top N pixels above the target element, which keeps section headings visible and clears sticky navbars. Negative values scroll past the element. A per-section `offset` overrides this default for that section only. *** ### `video_scroll_duration` default: `1500` How long each scroll movement takes, in milliseconds. Also the default per-section scroll duration in `video_scroll_to` mode. *** ### `video_rest_duration` default: `0` How long to pause between scroll movements, in milliseconds. In `video_scroll_to` mode this becomes the default per-section `wait` (falling back to 2000ms if unset). *** ### `video_prescroll_duration` default: `1000` How long to hold at the top of the page before scrolling begins, in milliseconds. *** ### `video_postscroll_duration` default: `1000` How long to keep recording after scrolling finishes, in milliseconds. *** ### `video_scroll_back` default: `true` Scroll back to the top of the page at the end of the recording. Set to false to end the video at the final scroll position. *** ### `video_scroll_back_duration` default: `2500` How long the final scroll back to the top takes, in milliseconds. *** ### `video_ease` default: `quadratic.inout` Easing function for scroll movements. Controls how each scroll accelerates and decelerates. Values are lower-case. Also the default per-section `ease` in `video_scroll_to` mode. The available values are: `linear.none` `quadratic.in` `quadratic.out` `quadratic.inout` `cubic.in` `cubic.out` `cubic.inout` `quartic.in` `quartic.out` `quartic.inout` `quintic.in` `quintic.out` `quintic.inout` `sinusoidal.in` `sinusoidal.out` `sinusoidal.inout` `exponential.in` `exponential.out` `exponential.inout` `circular.in` `circular.out` `circular.inout` `elastic.in` `elastic.out` `elastic.inout` `back.in` `back.out` `back.inout` `bounce.in` `bounce.out` `bounce.inout` #### `video_ease` Example *** ### `video_ease_end` default: `quadratic.inout` Easing function for the final scroll back to the top. Accepts the same values as `video_ease`. *** ### `video_scroll_distance` Override the distance of each scroll movement, in pixels. By default each movement covers roughly one viewport. Ignored in `video_scroll_to` mode. *** ### `video_sections` Stop the scroll after this many scroll movements, rather than scrolling the whole page. Ignored in `video_scroll_to` mode. *** ### `video_jitter` Randomise scroll timing by up to this fraction, for a more human, less mechanical feel. For example `0.2` varies each movement and pause by up to 20%. *** ### `video_warmup` default: `false` Perform an unrecorded scroll down and back up before recording starts, so lazy-loaded images and animations have already loaded when the real scroll happens. *** ## Cache Options Options to control how Urlbox caches your screenshots or PDF's. Please note that caching only applies to requests from render links. POST requests to the API are not cached. To remove a cached render before its `ttl` expires, send a `DELETE` request to the exact same render link URL (same path and query string as the original `GET`, excluding `force` and the token). The cache entry is keyed on the full set of render options, so a `DELETE` with a different query string targets a different entry. A successful purge responds `200` with `{"purged": true}`; if no cached render matched the supplied options, the API responds `404` with error code `CacheEntryNotFound`. Check that your query string exactly matches the original render's. Note that clients may still serve a previously fetched copy from their own HTTP cache until your `ttl` elapses. ### `force` default: `false` Generate a fresh render on each request, instead of getting a cached version. *** ### `unique` Pass a unique string such as a UUID, hash or timestamp, to have more control over when to generate a fresh screenshot or PDF. *** ### `ttl` default: `2592000` The duration to keep a screenshot or PDF in the cache, in seconds. ttl stands for 'time to live'. The default value is also the maximum value: `2592000` seconds (30 days). #### `ttl` Examples *** ## Request Options Options to configure the browser, before navigating to the URL ### `proxy` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above Pass in a proxy server address to make screenshot requests via that server in the format `[address]:[port]`. If proxy authentication is required, you can use the following format: `[user]:[password]@[address]:[port]`. *** ### `use_proxy` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above This uses the proxy you have stored on your [`project`](https://urlbox.com/dashboard/projects.md) in use to make screenshot requests via that server. *** ### `use_stealth` default: `false` Renders the page with a full, real Chrome browser set up the way a normal user's machine is. Standard renders streamline or disable some browser behaviours for speed; stealth renders leave everything in place, so the page sees an ordinary, consistent browsing environment. Use it when a page renders incompletely, or returns a challenge page or 403, under a plain render. It combines well with [`retry_on`](#retry_on) and [`retry_with`](#retry_with) (enable stealth only on retries, so you only pay its cost when a render needs it), and with a [`proxy`](#proxy) for sites that respond differently depending on the requesting network. Stealth renders are noticeably slower than standard renders, so avoid enabling it as a blanket default. *** ### `hide_headless` default: `false` A lighter-weight alternative to [`use_stealth`](#use_stealth). It runs Chrome with a set of plugins that fill in the properties headless Chrome normally leaves unset or empty (for example `navigator.webdriver`, the `chrome` runtime objects, and WebGL vendor strings), so the page sees the environment an ordinary desktop browser reports. [`use_stealth`](#use_stealth) is the stronger option and takes precedence if both are set. Reach for `hide_headless` when a page renders differently under headless Chrome but doesn't need the full stealth browser. *** ### `header` Only available on: [`hifi`](https://urlbox.com/pricing.md) and above Set a header on the request when loading the URL Example: To set the header with key `X-My-Header` to the value `SomeValue`, you would pass `header=X-My-Header%3DSomeValue`. This can be set multiple times, to set more than one header - e.g. `header=X-My-Header%3DSomeValue&header=X-My-Other-Header%3DSomeOtherValue`. As with all options passed via the query string, the header value must be URL encoded - so `X-My-Header=SomeValue` becomes `X-My-Header%3DSomeValue` in order to be interpreted correctly by Urlbox. #### `header` Examples *** ### `cookie` Sets a cookie on the request when loading the URL. Example: To set the cookie with key `Opt-In` to the value `yes`, you would set the value of this option to `Opt-In=yes`. Cookies can be passed as an array, to allow setting multiple cookies - e.g.`["Opt-In=yes","Session-Id=DMTIzNDU"]`. To achieve multiple cookies with render links, just set the cookie option multiple times, like `cookie=Opt-In%3Dyes&cookie=Session-Id%3DDMTIzNDU`. To set a specific domain on a cookie, you can do the following: `OptIn=yes;Domain=.mydomain.com`. You can set other attributes for the cookie such as `Path`, `HttpOnly` and `SameSite` #### `cookie` Examples *** ### `user_agent` Sets the `User-Agent` string for the request. The user agent identifies what browser/device is making the request, which can affect how websites render content. **Presets:** - `random` - Uses a random user-agent to help avoid bot detection - `mobile` - Uses a modern iPhone/Safari user-agent string - `desktop` - Uses a modern Chrome/macOS user-agent string **Why use this?** - Some websites serve different content based on the user agent (e.g., mobile vs desktop layouts) - Certain sites block requests from unknown or bot-like user agents - You may want to emulate how a specific browser or crawler sees a page **Testing your user agent:** Try rendering [httpbin.org/user-agent](https://httpbin.org/user-agent) to see exactly what user agent string is being sent. For a comprehensive list of user agent strings, see [useragents.me](https://www.useragents.me/). #### `user_agent` Examples *** ### `platform` default: `MacIntel` Sets the `navigator.platform` that the browser will report for the request. Useful for getting around certain scripts that detect the platform. #### `platform` Examples *** ### `accept_lang` default: `en-US` Sets an `Accept-Language` header on requests to the target URL #### `accept_lang` Examples *** ### `authorization` Sets an `Authorization` header on requests to the target URL. Can be used to pass an auth token through to the site in order to 'login' before rendering. #### `authorization` Examples *** ### `tz` default: `America/New_York` Emulate the timezone to use when rendering pages. By default the rendering browser reports a US timezone (`America/New_York` or `America/Los_Angeles`, depending on which of our regions renders your screenshot) so that its clock agrees with where our renderers connect from. Set `tz` explicitly to pin it. Renders on the `stable` engine channel still report UTC until the next promotion of `latest` to `stable` (see [`engine_version`](#engine_version)). This matters whenever the page derives anything from the browser's local clock: displayed dates and times, opening hours, "expires in" countdowns, and any cookie or token whose lifetime the page calculates client-side. If your renders need to be identical every time, or your page assumes UTC, set `tz=UTC`. Example: `tz=Europe/London`. A list of timezone ID's can be found here: [https://en.wikipedia.org/wiki/List\_of\_tz\_database\_time\_zones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) #### `tz` Examples *** ### `engine_version` default: `latest` Sets the version of the urlbox rendering engine to use when rendering the page. Renders default to `latest` unless you choose a version here or on your [project](https://urlbox.com/dashboard/projects.md). Pin `stable` when you'd rather pick up engine changes in batches, at the scheduled promotions of latest to stable, than as they ship. The available values are: `stable` `latest` `experimental` *** ### `certify` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above This creates a hash of the rendered file, timestamp and options providing proof that a render was taken at a given time. Returns a hash, timestamp and the options used to hash. Checkout our [`guide`](https://urlbox.com/guides/certify-a-screenshot.md) on certifying a render for more information. *** ## Wait Options Options to control how Urlbox waits for the page or elements to load before rendering. ### `delay` default: `0` The amount of time to wait before Urlbox captures a render in milliseconds. *** ### `timeout` default: `30000` The amount of time to wait for the requested URL to load, in milliseconds. The timeout value needs to be between 5,000 and 100,000 milliseconds. The default is 30000 or 30 seconds. *** ### `wait_until` default: `loaded` Waits until the specified DOM event has fired before capturing a render. The available options are: - `domloaded` (the `DOMContentLoaded` event is fired) - `mostrequestsfinished` (consider navigation to be finished when there are no more than 2 network connections for at least 500 ms) - `requestsfinished` (there are no more than 0 network connections for at least 500 ms) - `loaded` (the `load` event is fired) The available values are: `domloaded` `mostrequestsfinished` `requestsfinished` `loaded` #### `wait_until` Examples *** ### `wait_for` Waits for the element specified by this selector to be present in the DOM before taking a screenshot or PDF. By default, Urlbox will take a screenshot or PDF if the `wait_for` element is not found after waiting for the time specified by the [`wait_timeout`](#wait_timeout) option. If you prefer Urlbox to fail the request when the `wait_for` element is not found, pass [`fail_if_selector_missing=true`](#fail_if_selector_missing) #### `wait_for` Examples *** ### `wait_for_state` default: `attached` Whether the element specified by wait\_for should be visible or just present in the DOM. Visible means the element is attached to the DOM and has opacity > 0 and its width and height > 0 and doesn't have `visibility:hidden` set. The available values are: `visible` `attached` *** ### `wait_to_leave` Waits for the element specified by this selector to be absent from the DOM before taking a screenshot or PDF. A typical use-case would be waiting for loading spinners to be absent before taking a screenshot. By default, Urlbox will take a screenshot or PDF if the `wait_to_leave` element is still present after the time specified by the [`wait_timeout`](#wait_timeout) option. If you prefer Urlbox to fail the request when the `wait_to_leave` element is still present, pass [`fail_if_selector_present=true`](#fail_if_selector_present) #### `wait_to_leave` Examples *** ### `wait_timeout` default: `30000` The amount of time to wait for the [`wait_for`](#wait_for) element to appear, or the [`wait_to_leave`](#wait_to_leave) element to leave before continuing, in milliseconds. *** ## Fail Options Options to dictate how Urlbox handles certain scenarios. ### `fail_if_selector_missing` default: `false` Fails the request if the elements specified by `selector` or `wait_for` options are not found on the page after waiting for `wait_timeout`. #### `fail_if_selector_missing` Example *** ### `fail_if_selector_present` default: `false` Fails the request if the element specified by `wait_to_leave` option is found on the page after waiting for `wait_timeout`. #### `fail_if_selector_present` Example *** ### `fail_on` Pass in a specific HTTP status code (e.g., `"400"`, `"500"`) or an array of status codes (e.g., `["400", "404", "500"]`) as strings. Urlbox will fail the request if the final response status code matches any of the specified codes. #### `fail_on` Example *** ### `fail_on_4xx` default: `false` If `fail_on_4xx=true` and the requested URL returns a status code between 400 and 499, Urlbox fails the request with a 400 error, an error `code` of `fail_on_4xx`, and a message naming the status code (for example `Page returned 404 and fail_on_4xx was true`). #### `fail_on_4xx` Examples *** ### `fail_on_5xx` default: `false` If `fail_on_5xx=true` and the requested URL returns a status code between 500 and 599, Urlbox fails the request with a 400 error, an error `code` of `fail_on_5xx`, and a message naming the status code (for example `Page returned 500 and fail_on_5xx was true`). #### `fail_on_5xx` Examples *** ### `fail_on_except` Specify status codes to exclude from [`fail_on`](#fail_on), [`fail_on_4xx`](#fail_on_4xx), or [`fail_on_5xx`](#fail_on_5xx) checks. For example, if you want to fail on all 5xx errors except 503, use `fail_on_5xx=true` with `fail_on_except=503`. *** ### `retry_on` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above Automatically retry renders when specific conditions occur. Pass a single condition, a comma-separated string, or an array of conditions. When a condition matches, Urlbox will retry with exponential backoff (the delay doubles each time, starting at 1 second by default and capped at 30 seconds per wait) up to 2 times by default (3 total attempts including the original render). Use [`max_retries`](#max_retries) or [`max_attempts`](#max_attempts) to change this. Retrying stops early if the request approaches the overall 5 minute render budget. **HTTP status conditions** (retry based on the page's response): - **`4xx`** - Retry when the page returns any 4xx status. This range deliberately skips retrying when the failure looks like a problem with the request itself rather than a block (for example a missing selector or an invalid option), since those would fail identically on every attempt. List codes like `403`/`429` explicitly to always retry them. - **`5xx`** - Retry when the page returns any 5xx status - **`404`**, **`429`**, **`503`**, etc. - Retry on specific status codes **Engine conditions** (retry when Urlbox encounters an internal error): - **`timeout`** - Retry when the render times out - **`crash`** - Retry when the browser crashes **Quality conditions:** - **`small_size`** - Retry when the screenshot is smaller than [`min_size_bytes`](#min_size_bytes) **Special values:** - **`all`** - Retry on any of the conditions above **Examples:** - `retry_on: "4xx"` - Retry when the page returns any 4xx status - `retry_on: ["429", "503"]` - Retry on rate limiting or service unavailable - `retry_on: "timeout,crash"` - Retry on engine failures only - `retry_on: "5xx,timeout"` - Retry on page 5xx errors or timeouts **Note:** If a condition matches both `retry_on` and [`fail_on`](#fail_on), the request will be retried first. Use [`fail_on_except`](#fail_on_except) to mark specific status codes as acceptable (won't retry or fail). *** ### `retry_with` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above Change render options on retry attempts triggered by [`retry_on`](#retry_on). Instead of retrying with the exact same options, each retry re-runs the render with the `retry_with` options merged over the original request, so you can escalate progressively: try a cheap, plain render first, and only add stealth or a proxy if the render fails. `retry_with` has no effect on its own; it only applies when [`retry_on`](#retry_on) triggers a retry. Because the value is a nested object, use it with JSON POST requests to the render endpoints. **Single object** - applied to every retry attempt: ```json { "url": "example.com", "retry_on": ["403", "429", "timeout"], "retry_with": { "use_stealth": true, "use_proxy": true } } ``` **Array of objects** - progressive escalation. The first retry uses the first element, the second retry uses the second element, and so on. If there are more retries than elements, the last element is reused for the remaining retries. For example, if a site rate-limits or bot-blocks you (429 or 403 responses), you can escalate through your own proxies from cheapest to most expensive, so the expensive bandwidth is only spent on renders that actually got blocked: ```json { "url": "example.com", "retry_on": ["403", "429"], "max_retries": 3, "retry_delay_ms": 2000, "retry_with": [ { "proxy": "user:pass@dc1.cheapproxy.example.com:8080" }, { "proxy": "user:pass@isp.midproxy.example.com:8080" }, { "proxy": "user:pass@resi.premiumproxy.example.com:9000" } ] } ``` The first attempt runs without a proxy. If the page responds 403 or 429, the first retry goes through the cheap datacenter proxy, the second through the mid-tier one, and the third through the residential proxy. Entries aren't limited to the [`proxy`](#proxy) option: any retry-compatible option works, for example `{ "use_stealth": true, "use_proxy": true }` to enable [`use_stealth`](#use_stealth) mode and route through the proxy saved on your [project](https://urlbox.com/dashboard/projects.md) (like [`use_proxy`](#use_proxy)). See the [proxies guide](https://urlbox.com/docs/guides/proxies.md#escalating-through-proxies-on-retry) for a walkthrough of this pattern. **Merging rules:** - Each retry's options are the original request options with that attempt's `retry_with` entry merged on top. - Setting an option to `null` removes it from that retry attempt - e.g. `{ "proxy": null }` retries without the proxy from the original request. - Options you don't mention are left unchanged. **Retry-compatible options:** only options that affect how the page is fetched and rendered can be changed on retry. These include proxy and network options ([`proxy`](#proxy), [`use_proxy`](#use_proxy), [`user_agent`](#user_agent)), stealth options ([`use_stealth`](#use_stealth), [`hide_headless`](#hide_headless)), content blocking ([`block_ads`](#block_ads), [`hide_cookie_banners`](#hide_cookie_banners), [`block_urls`](#block_urls)), interaction and waiting ([`click_accept`](#click_accept), [`click`](#click), [`wait_until`](#wait_until), [`wait_for`](#wait_for), [`delay`](#delay)), viewport ([`width`](#width), [`height`](#height), [`retina`](#retina)), page modifications ([`js`](#js), [`css`](#css), [`hide_selector`](#hide_selector)), request headers and cookies ([`header`](#header), [`cookie`](#cookie), [`authorization`](#authorization), [`accept_lang`](#accept_lang)), and [`timeout`](#timeout). Options that change the output itself (like `format` or `full_page`) cannot be changed between attempts. *** ### `max_retries` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above default: `2` Maximum number of retry attempts when using [`retry_on`](#retry_on). Must be between 0 and 5. If [`max_attempts`](#max_attempts) is also set, `max_attempts` takes precedence. *** ### `max_attempts` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above default: `3` Maximum total number of render attempts (the original render plus retries) when using [`retry_on`](#retry_on). Must be between 0 and 5. An alternative to [`max_retries`](#max_retries): `max_attempts` is equivalent to `max_retries + 1`, and takes precedence over it when both are set. *** ### `retry_delay_ms` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above default: `1000` Base delay in milliseconds between retry attempts. The delay doubles with each retry (exponential backoff), with each individual wait capped at 30 seconds. Must be between 100 and 60000. *** ### `min_size_bytes` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above default: `1000` Minimum expected file size in bytes. Used with [`retry_on: "small_size"`](#retry_on) to retry when the screenshot is smaller than expected, which may indicate an error page was captured instead of the intended content. Must be at least 100. *** ## Page Options Options to modify the page state before taking a screenshot or PDF ### `scroll_to` Scroll, to either an element or to a pixel offset from the top, before taking a screenshot #### `scroll_to` Examples *** ### `click` Specifies an element selector to click before generating a screenshot or PDF Example: `#clickme` would click an element with `id="clickme"`. Can be used multiple times to simulate multiple sequential click events. If the selector matches multiple elements, only the first element will be clicked. #### `click` Examples *** ### `click_all` Specifies an element selector to click before generating a screenshot or PDF Example: `.clickme` would click all elements with `class="clickme"`. Can be used multiple times to simulate multiple sequential click events. If the selector matches multiple elements, all elements will be clicked. #### `click_all` Example *** ### `hover` Specifies an element selector to hover over before generating a screenshot or PDF Example: `#hoverme` would hover over the element with `id="hoverme"` #### `hover` Examples *** ### `bg_color` Specify a hex code or CSS color string to use as the background color Some websites don't set a body background colour, and will show up as transparent backgrounds with PNG, or black when using JPG. Use this setting to set a background colour. If the website explicitly sets a transparent background on the html or body elements, this setting will be overridden. *** ### `disable_js` default: `false` Turns off javascript on the target URL. \~> Enabling this option will prevent `full_page=true` and many other options, because having javascript disabled prevents Urlbox from evaluating code inside the page's context. #### `disable_js` Examples *** ### `show_certificate_errors` default: `false` Shows browser certificate errors for pages with invalid HTTPS certificates. By default, Urlbox ignores certificate errors so pages with expired, self-signed, or otherwise invalid certificates can still render. *** ## Full Page Options Advanced options to control how Urlbox takes full page screenshots, when `full_page=true` ### `full_page_mode` default: `stitch` Whether to use scroll and stitch algorithm (the default) to render a full page screenshot, or to use the native full page screenshot algorithm, which is faster, but can be less accurate on some sites. The available values are: `stitch` `native` *** ### `full_width` default: `false` When full\_page=true, specify whether to capture the full width of the website, for example if the site is horizontally scrolling. *** ### `allow_infinite` By default, when Urlbox detects an infinite scrolling page, it does not attempt to continue scrolling to the bottom, as this could result in infinite scrolling! If you want to override this behaviour, pass `true` for this option. *** ### `skip_scroll` default: `false` Enabling `skip_scroll` will speed up renders by skipping an initial scroll through the page, which is used to trigger any lazy loading elements. #### `skip_scroll` Examples *** ### `detect_full_height` Some pages have full-height backgrounds whose heights are set to 100% of the viewport. This can cause the backgrounds to get stretched when making a full page screenshot. If you are seeing this behaviour in your full page screenshots, pass `true` for this option. *** ### `max_section_height` default: `4096` When Urlbox takes a `full_page` screenshot, the maximum height of each image section is set to 4096 pixels. If a sites height is greater than this value, Urlbox will start splitting the screenshot into sections. Sometimes it is worthwhile experimenting with this number. *** ### `scroll_increment` Sets how many pixels to scroll when scrolling the page to trigger lazy loading elements. By default, the scroll increment is set to the browser viewport height. Some pages' lazy loading elements only trigger when the scroll increment is smaller than this, however, e.g. 400px. *** ### `scroll_delay` When Urlbox decides to split a screenshot into multiple sections, the scroll delay is the time to wait between taking the screenshots of each individual section, in milliseconds. While Urlbox does detect animations, and attempts to wait for them before taking a screenshot, this option could be used to force Urlbox to wait for a certain amount of time after scrolling to the next section, to wait for things like animations to finish. *** ## Highlighting Options Options for highlighting a given string on the page. These are useful for either highlighting or hiding (if you use the same foreground and background) words or a given set of characters. ### `highlight` Specify a string to highlight on the page before capturing a screenshot or PDF. To highlight multiple words, separate words with a pipe character e.g. Hello|World #### `highlight` Example *** ### `highlightfg` default: `white` Specify the text color of the highlighted word. #### `highlightfg` Examples *** ### `highlightbg` default: `red` Specify the background color of the highlighted word. #### `highlightbg` Examples *** ## Geolocation Options Options for the geolocation API. ### `latitude` Sets the latitude used to emulate the Geolocation API. #### `latitude` Example *** ### `longitude` Sets the longitude used to emulate the Geolocation API. #### `longitude` Example *** ### `accuracy` Sets the accurate of the Geolocation API in metres. #### `accuracy` Examples *** ## Side Render Options Options for generating side renders: extra artifacts captured from the same page load as your main render, such as the page's HTML, an MHTML snapshot, a markdown conversion, page metadata, extracted content and thumbnails. Side renders don't trigger a second render: everything is produced while the page is already loaded, and each artifact is saved alongside the main render and returned as an extra URL field in the JSON response, so make sure you are using the API or [`response_type=json`](#response_type) to see them. See the [side renders guide](https://urlbox.com/docs/guides/side-renders.md) for a walkthrough. Side render and thumbnail file sizes count toward your render's output size, which is billed at one render credit per 5MB of file size over the included allowance. ### `save_markdown` default: `false` Converts the rendered page to markdown and saves it alongside the main render, so you can capture a screenshot and an LLM-friendly text version of the page in one request. The JSON response gains a `markdownUrl` field linking to the saved `.md` file. To get markdown as the main render itself, use [`format=md`](#format) instead. #### `save_markdown` Example *** ### `save_html` default: `false` Saves the page's rendered HTML alongside the main render. The HTML is captured from the live DOM after the page has finished loading, so it includes any changes made by javascript. The JSON response gains an `htmlUrl` field linking to the saved `.html` file. #### `save_html` Example *** ### `save_metadata` default: `false` Extracts the page's metadata (title, description, author, canonical URL, open graph tags, twitter card tags and other meta tags, along with the requested and resolved URLs) and saves it as a JSON file alongside the main render. The JSON response gains a `metadataUrl` field linking to the saved file, and the metadata is also returned inline in the `metadata` field. #### `save_metadata` Example *** ### `save_headings` default: `false` Extracts every heading (`h1`-`h6`) from the page and saves them as a JSON side render. Each entry contains the heading level, its text, and its `id` when present - useful for building a table of contents or checking a page's structure. The JSON response gains a `headingsUrl` field linking to the saved file. #### `save_headings` Example *** ### `save_tables` default: `false` Extracts every HTML `<table>` on the page and saves them as a JSON side render. Each table contains its cells organised as rows and columns, a flag per row indicating whether it is a header row, and a markdown rendering of the whole table. The JSON response gains a `tablesUrl` field linking to the saved file. #### `save_tables` Example *** ### `save_structured_data` default: `false` Extracts structured data embedded in the page, such as JSON-LD / schema.org markup, and saves it as a JSON side render. Each entry contains the data type, the raw JSON and, when detected, the schema type (e.g. `Product` or `Article`). The JSON response gains a `structuredDataUrl` field linking to the saved file. #### `save_structured_data` Example *** ### `save_links` default: `false` Extracts every link on the page - resolved to absolute URLs, along with the link text - and adds them to the page metadata under `links`. The metadata is returned in the `metadata` field of the JSON response and saved as a JSON side render linked from `metadataUrl`. #### `save_links` Example *** ### `save_clicks` default: `false` Records the elements Urlbox clicked automatically during the render - for example the cookie-banner buttons clicked by [`click_accept`](#click_accept) - and adds them to the page metadata under `clickedOn`, including each clicked element's selector, tag name, classes and text. Useful for auditing exactly what was dismissed before your screenshot was taken. The metadata is returned in the `metadata` field of the JSON response and saved as a JSON side render linked from `metadataUrl`. #### `save_clicks` Example *** ### `save_cookies` default: `false` Saves the cookies set in the browser by the end of the render into the page metadata, as an array of cookie strings under `cookies` plus a `cookiesSaved` count. The metadata is returned in the `metadata` field of the JSON response and saved as a JSON side render linked from `metadataUrl`. #### `save_cookies` Example *** ### `save_headers` default: `false` Includes the target page's HTTP response headers in the JSON response. By default the `response` object contains the status code and requested/resolved URLs only; setting `save_headers=true` adds a `headers` object containing the headers the target site responded with. #### `save_headers` Example *** ### `save_http_headers` default: `false` Alias of [`save_headers`](#save_headers) - includes the target page's HTTP response headers in the `response.headers` field of the JSON response. #### `save_http_headers` Example *** ### `save_resource_info` default: `false` Saves a JSON debug artifact listing every resource the page requested during the render - each entry records the URL, HTTP method, resource type, content type, status code, transferred and inflated byte sizes, and encoding. This is the data Urlbox uses to calculate the render's bandwidth. The file is saved to storage alongside the render; its location is not returned in the standard render response, but is visible in the render's details in your dashboard, making this primarily a debugging aid. #### `save_resource_info` Example *** ### `save_mhtml` default: `false` Saves an MHTML snapshot of the page alongside the main render. MHTML bundles the page and its resources into a single file that can be opened in a browser for offline viewing. The JSON response gains an `mhtmlUrl` field linking to the saved `.mhtml` file. #### `save_mhtml` Example *** ### `thumbnails` Generates up to 5 thumbnails of the main render, resized from the same captured image - no extra render is performed. Applies to image formats (`png`, `jpeg`, `webp`, `avif`); each thumbnail keeps the main render's format. Because the value is an array of objects, use it with JSON POST requests to the render endpoints. Each thumbnail object accepts: - `key` - a name for the thumbnail, up to 10 characters. Used as the file suffix and as the thumbnail's `key` in the response. When omitted, a key is derived from the preset or dimensions (e.g. `400`, `400x300` or `sm`). - `preset` - a named size relative to the main render's dimensions: `xs` (10%), `sm` (20%), `md` (30%), `lg` (40%), `xl` (50%), `2xl` (60%), `3xl` (70%), `4xl` (80%), `5xl` (90%), or the fractions `1/4`, `1/2` and `3/4`. - `size` - sets both the width and height, in pixels. Must be between 10 and 2000. - `width` / `height` - individual pixel dimensions, each between 10 and 2000. Ignored on an axis where a `preset` applies. - `fit` - how the image should be resized to fit the dimensions: `cover`, `contain`, `fill`, `inside` or `outside` (see [`img_fit`](#img_fit) for what each does). Defaults to the request's [`img_fit`](#img_fit), or `cover`. - `position` - how the image is positioned when `fit` is `cover` or `contain` (see [`img_position`](#img_position)). - `bg` - background colour used when `fit` leaves empty space, e.g. with `contain`. Defaults to the request's [`img_bg`](#img_bg) or [`bg_color`](#bg_color), then black. - `suffix` - overrides the file name suffix used for the thumbnail in storage. - `presigned_url` - an S3 presigned URL to upload this thumbnail to, if you want it delivered straight into your own bucket. Each thumbnail must resolve to a unique key. The JSON response gains a `thumbnails` array with one `{ "key": ..., "location": ..., "size": ... }` entry per thumbnail - set [`thumbnails_object`](#thumbnails_object) to get them keyed by name instead. Thumbnail file sizes count toward the render's output size for billing, like other side renders. #### `thumbnails` Examples *** ### `thumbnails_object` default: `false` Returns the [`thumbnails`](#thumbnails) results as an object keyed by each thumbnail's `key`, instead of an array - so `"thumbnails": [{ "key": "small", "location": ..., "size": ... }]` becomes `"thumbnails": { "small": { "location": ..., "size": ... } }`. Useful when you want to look thumbnails up by name rather than position. #### `thumbnails_object` Example *** ## Storage Options Options related to storing renders in your own S3-compatible or Azure Blob Storage bucket. ### `use_s3` Only available on: [`hifi`](https://urlbox.com/pricing.md) and above default: `false` Save the render directly to the S3 (or S3-Compatible) bucket configured on your account. Mutually exclusive with [`use_azure`](#use_azure) - a request setting both fails. *** ### `s3_path` Only available on: [`hifi`](https://urlbox.com/pricing.md) and above Sets the S3 path, including subdirectories and the filename, to use when saving the render in your S3-compatible bucket. \~> The extension (e.g. .png, .jpg or .pdf) will be provided automatically, and should not be included in `s3_path`. *** ### `no_suffix` Only available on: [`hifi`](https://urlbox.com/pricing.md) and above By default, urlbox adds the file extension (e.g. `.png`, `.jpg`, `.pdf` etc) to the `s3_path` (or [`azure_path`](#azure_path)). If `no_suffix=true`, the file extension will NOT be added to the path. *** ### `use_azure` Only available on: [`hifi`](https://urlbox.com/pricing.md) and above default: `false` Save the render directly to the Azure Blob Storage container configured on your project. Azure is not S3-compatible, so it has its own credentials (storage account, container and SAS token) and options - see the [Azure Blob Storage guide](https://urlbox.com/docs/storage/configure-azure-blob-storage.md) for setup. Mutually exclusive with [`use_s3`](#use_s3) - a request setting both fails. *** ### `azure_path` Only available on: [`hifi`](https://urlbox.com/pricing.md) and above Sets the blob path, including subdirectories and the filename, to use when saving the render in your Azure container - the Azure equivalent of [`s3_path`](#s3_path). Defaults to `renders/{year}/{month}/{day}/{renderId}`. \~> The extension (e.g. .png, .jpg or .pdf) will be provided automatically, and should not be included in `azure_path`. *** ### `s3_bucket` Only available on: [`hifi`](https://urlbox.com/pricing.md) and above Overrides the configured bucket to use when saving the render. *** ### `s3_endpoint` Only available on: [`hifi`](https://urlbox.com/pricing.md) and above You can change the endpoint URL to use an S3 compatible storage provider e.g. DigitalOcean Spaces, Minio, Wasabi, Cloudflare R2 and more. *** ### `s3_region` Only available on: [`hifi`](https://urlbox.com/pricing.md) and above Override the configured S3 region when saving the render. *** ### `cdn_host` Only available on: [`hifi`](https://urlbox.com/pricing.md) and above If your custom bucket is fronted by a CDN, you can set the host name here. *** ### `s3_storageclass` Only available on: [`hifi`](https://urlbox.com/pricing.md) and above default: `standard` Sets the s3 storage class.

By passing an llm\_schema without this option, it will default to responding with an object specified by your JSON Schema. If you choose Array, the response will be an array of your provided JSON Schema. If you choose enum, you can provide an array of strings as your schema, and your LLM will respond only with a value from that enum. The available values are: `object` `array` `enum` *** ### `llm_schema` Only available on: [`ultra`](https://urlbox.com/pricing.md) and above This is the JSON schema or string\[] provided which we will pass over to your LLM. Your LLM provider will respond with a structured output (if supported by your provider) according to that schema. Please take a look at the various resources on the [JSON Schema](https://json-schema.org/tools?query=\&sortBy=name\&sortOrder=ascending\&groupBy=toolingTypes\&licenses=\&languages=\&drafts=\&toolingTypes=\&environments=\&showObsolete=false\&supportsBowtie=false) website for more information on designing and validating a JSON schema. #### `llm_schema` Examples --- # Post API > Post options to the screenshot API Source: https://urlbox.com/docs/postapi Last updated: 2026-07-31 --- You can also `POST` options to the API and get a result asynchronously. ## Authentication The `POST` endpoint uses HTTP Basic authentication. Pass your **secret** key as the username. ## Usage The endpoint for POSTing options to the API is: [https://api.urlbox.com/v1/render](https://api.urlbox.com/v1/render) ## Required Options The endpoint accepts the same [API options](./options) as the `GET` endpoints. Options can be specified in either camelCase or snake\_case. The only required options are either a `url` or a `html` payload. Options can be sent as `JSON` or `formdata` | Name | Type | Description | | :--------- | :------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **`url`** | `String` | The fully qualified URL to a public webpage. Such as `https://htmlcsstoimage.com`. When passed this will override the html param and will generate a screenshot of the url. | | **`html`** | `String` | This is the HTML you want to render. You can send an HTML snippet (`<div>Your content</div>`) or an entire webpage. | ## Response ## Examples curl - --- # Render Links > Create screenshots, PDFs and other renders by embedding a single link in your HTML or emails. Source: https://urlbox.com/docs/render-links Last updated: 2026-07-31 --- A render link is a dynamic URL that can be used directly to request a render from Urlbox's API. The format of a render link is: [https://api.urlbox.com/v1/api-key/token/format?url=example.com](https://api.urlbox.com/v1/api-key/token/format?url=example.com) To create a valid render link: 1. Replace api key with your project api key. 2. Replace token with a [signed token](#authentication).\* 3. Replace format with the desired [output format](https://urlbox.com/docs/options.md#format). 4. Construct a query string made up of various [render options](https://urlbox.com/docs/options.md). \* this step is optional. If you don't want to use an authenticated render link, you can leave the token out. It is recommended to use authenticated render links when using render links in public. ## Authentication Authentication is through generating the signed token, which is a HMAC-SHA256 hash of the query string, signed by your project secret key. The token generation should therefore be done server-side, and not in the browser, as you don't want to expose your secret key to the public. Here is an example using node.js, with the query string set to url=example.com\&width=600\&height=400 ```js import hmacSha256 from "crypto-js/hmac-sha256"; const secretKey = "YOUR_URLBOX_SECRET"; const options = "url=example.com&width=600&height=400"; const token = hmacSha256(options, secretKey).toString(); ``` The same example, in Python: ```python import hmac import hashlib secret_key = "YOUR_URLBOX_SECRET" options = "url=example.com&width=600&height=400" token = hmac.new(bytes(secret_key , 'latin-1'), msg = bytes(options , 'latin-1'), digestmod = hashlib.sha256).hexdigest() ``` In Ruby: ```ruby require 'openssl' secret_key = "YOUR_URLBOX_SECRET" options = "url=example.com&width=600&height=400" token = OpenSSL::HMAC.hexdigest('sha256', secret_key, options) ``` and in PHP: ```php $secret_key = "YOUR_URLBOX_SECRET"; $options = "url=example.com&width=600&height=400"; $token = hash_hmac('sha256', $options, $secret_key); ``` You can also check the token is correct from the command line: ```sh echo -n "url=example.com&width=600&height=400" | openssl sha256 -hmac "YOUR_URLBOX_SECRET" ``` ### Forcing Secure Render Links If you want to force render links to be authenticated, you can enable the Force Secure Render Links option in your project's settings. Any render links requested without a valid token will receive a `401 Unauthorized` response. ## Options The options portion of the render link is a query string made up of various [render options](https://urlbox.com/docs/options.md). These are passed in as `key=value` pairs, where the key is the option name and concatenated together with `&` characters. The only required option is one of [`url`](https://urlbox.com/docs/options.md#url) or [`html`](https://urlbox.com/docs/options.md#html), which specifies the URL or HTML you want to render. When rendering large payloads of HTML, (or custom [`js`](https://urlbox.com/docs/options.md#js) or [`css`](https://urlbox.com/docs/options.md#css)) in order to avoid passing around a huge render link, and avoiding the maximum URL length, it is recommended to use the JSON based [REST API](https://urlbox.com/docs/api.md), to pass the HTML in as a JSON or form-encoded payload. Because the options are passed in as the query string part of the render link, you must URL encode any special characters in the render options values. See the [URL Encoding](#url-encoding) section for more details. ## Response The response from the API will be the binary data in the format you specified. For example, when the format is `png`, the Content-Type of the response will be an `image/png` PNG image. This means the render link can be embedded directly into an HTML `<img>` tag on your page or in an email, or in a `<meta>` tag for open graph images to be unfurled across various social media and messaging platforms. You can request a JSON response by setting the [`response_type`](https://urlbox.com/docs/options.md#response_type) option to `json`. This will return a JSON object with the following properties: ```json { "renderUrl":"path-to-temporary-url-of-render", "size":"size-of-render-in-bytes", "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299 } ``` Please note that when requesting a JSON response, the `renderUrl` is a temporary URL and will **not** be cached. It will expire after a minimum of 30 days or the `ttl` you have set. To keep the image, you'll need to download it, or tell Urlbox to [save it to your cloud bucket](https://urlbox.com/docs/guides/s3.md). ## Caching and Auto Refreshing Render links are cached for 30 days by default. This means that if you request the same render link twice within 30 days, the second request will return the same render as the first request. Once the cache expires, the next time a render link is requested, the render will be generated again. The cache expiry time is a way of controlling how fresh, or stale, your screenshots are. To reduce the cache duration time, set the [`ttl`](https://urlbox.com/docs/options.md#ttl) option to the number of seconds you want the render to be cached for. For example, to cache the render for 1 hour, set `ttl=3600`. ## Deduplication Render links are deduplicated, when two duplicate render links are requested at the same time, the second request will receive a `307 Temporary Redirect` to continue waiting for the first request. ## Long Running Requests Requests will receive a `307 Temporary Redirect` after 95 seconds. The `Location` header will contain the URL to follow to continue waiting for the render to finish processing. The redirect timeout can be configured using the [`redirect_after`](https://urlbox.com/docs/options.md#redirect_after) option. ## Errors If there is an error with the request, the API will return a `4xx` or `5xx` status code. The response body will contain a JSON object with the following properties: ```json { "error": { "message": "error-message", "code": "error-code", } } ``` ## URL Encoding Because the options are passed in the query string, any special characters in the URL must be [URL encoded](https://developer.mozilla.org/en-US/docs/Glossary/Percent-encoding). Sometimes referred to as percent encoding, this is a way of encoding special characters such that they can be passed in a URL and decoded on the other side. For example, trying to render a URL that itself has a query string: ```sh url=https://example.com/?foo=bar&baz=qux ``` If you were to pass this URL directly in the query string, the `&` characters would be interpreted as the start of a new option, and the URL would be truncated to `https://example.com/?foo=bar`. To avoid this, you must URL encode the URL before passing it in the query string. The URL encoded version of the above URL would be: ```sh url=https%3A%2F%2Fexample.com%2F%3Ffoo%3Dbar%2526baz%253Dqux ``` Many languages have built in functions for URL encoding, in JavaScript you would use the `encodeURIComponent` function: ```js const encodedString = encodeURIComponent(originalString); ``` In Python use the `quote` function from the `urllib.parse` module. ```python from urllib.parse import quote encoded_string = quote(original_string) ``` In Ruby, use the `CGI.escape` method from the `cgi` module. ```ruby require 'cgi' encoded_string = CGI.escape(original_string) ``` In PHP, use the `rawurlencode` function. ```php $encoded_string = rawurlencode($original_string); ``` In Golang, use the `PathEscape` function from the `net/url` package. ```go import "net/url" encodedString := url.PathEscape(originalString) ``` In C#, use the `EscapeDataString` method from the `System.Uri` class. ```csharp string encodedString = Uri.EscapeDataString(originalString); ``` In Java, use the `URLEncoder.encode` method. Note that you also have to specify the encoding, which in most cases would be "UTF-8". ```java import java.io.UnsupportedEncodingException; import java.net.URLEncoder; try { String encodedString = URLEncoder.encode(originalString, "UTF-8"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } ``` ## URI Length limit When passing in large payloads, for example [`html`](https://urlbox.com/docs/options.md#html), [`js`](https://urlbox.com/docs/options.md#js) or [`css`](https://urlbox.com/docs/options.md#css), you may run into the maximum URI length limit of 2048 characters. To avoid this, switch to using the JSON based [REST API](https://urlbox.com/docs/api.md), where you can `POST` the HTML in as a JSON or form-encoded payload. ## Examples ### Render a full page screenshot of Urlbox Create the render link, using the options: `url=https://urlbox.com` and `full_page=true`. [https://api.urlbox.com/v1/api-key/token/png?url=https%3A%2F%2Furlbox.com\&full\_page=true](https://api.urlbox.com/v1/api-key/token/png?url=https%3A%2F%2Furlbox.com\&full_page=true) Put the generated render link into an `<img>` tag: ```html <img src="https://api.urlbox.com/v1/ca482d7e-9417-4569-90fe-80f7c5e1c781/4dfa2abf70ae21f3ab8dff5023ecd08334f8527d/png?url=https%3A%2F%2Furlbox.com&full_page=true"/> ``` and the result is: --- # Webhooks > Get notified when a screenshot has been rendered. Source: https://urlbox.com/docs/webhooks Last updated: 2026-07-31 --- Webhooks allow your application to receive information when a render, such as a screenshot, has been generated. This allows you to request renders asynchronously. ## Using webhooks Pass a webhook URL in as the `webhook_url` option and Urlbox will send a `POST` request to that URL with data about the render once it has completed rendering, or an error has occurred. ```zsh curl -X POST \ https://api.urlbox.com/v1/render \ -H 'Authorization: Bearer your-urlbox-secret' \ -H 'Content-Type: application/json' \ -d '{"url":"example.com", "webhook_url":"https://example.com/webhooks/urlbox"}' ``` This will result in a response like the following being POSTed to `https://example.com/webhooks/urlbox` once the render is complete: ```json { "event": "render.succeeded", "renderId": "19a59ab6-a5aa-4cde-86cb-d2b23302fd84", "result": { "renderUrl": "https://renders.urlbox.com/urlbox1/renders/6215a3df94d7588f7d910513/2024/1/11/19a59ab6-a5aa-4cde-86cb-d2b23302fd84.png", "size": 34097, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299 }, "meta": { "startTime": "2024-01-11T17:49:18.593Z", "endTime": "2024-01-11T17:49:21.103Z" } } ``` If there is an error during rendering, an example webhook payload will look similar to: ```json { "event": "render.failed", "renderId": "30044645-cfa3-45d6-b7c1-3c6dc3272af6", "error": { "message": "Page returned 400 and fail_on_4xx was true" }, "meta": { "startTime": "2024-01-11T22:57:34.265Z", "endTime": "2024-01-11T22:57:36.328Z" }, } ``` Webhooks are often used in combination with our [S3-compatible storage](https://urlbox.com/docs/guides/s3.md) making it easy for you to gather large numbers of screenshots asynchronously. ## Verify Webhook In order to verify that the webhook is being sent by Urlbox, you can use the `X-Urlbox-Signature` header sent with the webhook. You will require your webhook secret, which you can find in the Urlbox dashboard in the project settings. The webhook signature is sent in the form `t={timestamp},sha256={token}`. Your code should extract the `timestamp` and `token` values from the received header. You should then generate a HMAC-SHA256 of the timestamp value appended with a full-stop (period i.e. '.' ), which is then appended to the JSON stringified body of the webhook request body: `{timestamp}.{JSON stringified webhook payload}` ### Example For example, let's say the webhook payload you received was: ```json { "event": "render.succeeded", "renderId": "e9617143-2a95-4962-9cc9-d72f3c413b9c", "result": { "renderUrl": "https://renders.urlbox.com/urlbox1/renders/571f54138cd8b877077d3788/2024/1/11/e9617143-2a95-4962-9cc9-d72f3c413b9c.png", "size": 359081, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299 }, "meta": { "startTime": "2024-01-11T23:32:11.908Z", "endTime": "2024-01-11T23:33:32.500Z" } } ``` and the timestamp is `1705016013`, then the timestamp value appended with a full-stop (period i.e. '.' ) and with the JSON stringified webhook payload would look like: ```js let payload = `1705016013.{"event":"render.succeeded","renderId":"e9617143-2a95-4962-9cc9-d72f3c413b9c","result":{"renderUrl":"https://renders.urlbox.com/urlbox1/renders/571f54138cd8b877077d3788/2024/1/11/e9617143-2a95-4962-9cc9-d72f3c413b9c.png","size":359081,"renderTime":6609,"queueTime":127,"bandwidth":9429299},"meta":{"startTime":"2024-01-11T23:32:11.908Z","endTime":"2024-01-11T23:33:32.500Z"}}`; ``` We then create a HMAC-SHA256 token of the above string using your webhook secret as the key: ```js let ourToken = crypto .createHmac("sha256", YOUR_WEBHOOK_SECRET) .update(payload) .digest("hex"); ``` *(This example is using nodejs, but every language will have equivalent functionality to create a HMAC-SHA256 token)* Now we can compare the token we have generated, with the token embedded in the `X-Urlbox-Signature` header. If they match, we know that the request has been legitimately sent from Urlbox. #### Command Line If you need a way to test your own token generation code, you can generate a HMAC-SHA256 on the command line with the following command: ```zsh echo -n '1705016013.{"event":"render.succeeded","renderId":"e9617143-2a95-4962-9cc9-d72f3c413b9c","result":{"renderUrl":"https://renders.urlbox.com/urlbox1/renders/571f54138cd8b877077d3788/2024/1/11/e9617143-2a95-4962-9cc9-d72f3c413b9c.png","size":359081,"renderTime":6609,"queueTime":127,"bandwidth":9429299},"meta":{"startTime":"2024-01-11T23:32:11.908Z","endTime":"2024-01-11T23:33:32.500Z"}}' | openssl dgst -sha256 -hmac 'your_webhook_secret' > SHA2-256(stdin)= 861986740b3b3c8afee299afe74ff7a6249271c776b3efe5b5fd184201f1a07e ``` This token would match the X-Urlbox-Signature header's token: ```zsh X-Urlbox-Signature: t=1705016013,sha256=861986740b3b3c8afee299afe74ff7a6249271c776b3efe5b5fd184201f1a07e ``` --- # How to find out your usage > How to find out your usage Source: https://urlbox.com/docs/api/get-usage Last updated: 2026-07-31 --- When receiving a response from Urlbox, it will contain a number of useful headers that you can use to see your current usage: ```http x-urlbox-request-id: 9a20ac3c-dd71-4906-8025-3e6f01434dce x-urlbox-accepted-by: devapi x-renders-used: 79 x-renders-allowed: 100 x-renders-reset: Sat May 25 2024 14:18:57 GMT+0100 (British Summer Time) x-renders-remaining: 21 x-urlbox-cache-status: MISS x-ratelimit-limit: 250 x-ratelimit-remaining: 249 x-ratelimit-reset: 1695661076 x-ratelimit-resetdate: Mon, 25 Sep 2023 16:57:56 GMT x-urlbox-rendered-by: enginelocal x-urlbox-render-time: 36749 ``` ## Usage Headers ### x-renders-used This header shows how many renders your account has used in the current billing period. ### x-renders-allowed This shows the number of renders you are allowed in the current billing period. ### x-renders-remaining This shows the number of renders you have remaining in the current billing period. ### x-renders-reset This shows the date and time when your renders will reset to 0. ## Rate Limit Headers ### x-ratelimit-limit This shows the number of requests you are allowed to make in the rate limit window (1 minute). ### x-ratelimit-remaining This shows the number of requests you have remaining in the rate limit window (1 minute). ### x-ratelimit-reset This shows the date when the rate limit window resets. ### x-ratelimit-resetdate This shows the date and time when the rate limit window resets. ## Other Headers ### x-urlbox-request-id This shows the unique request ID for this request.

If the response was not served from cache, it will show `MISS`. ### x-urlbox-rendered-by This shows which rendering engine was used to render the screenshot. ### x-urlbox-render-time This shows how long it took to render the screenshot in milliseconds. --- # Projects > Learn about Projects and how to use them. Source: https://urlbox.com/docs/api/projects Last updated: 2026-07-31 --- A Project is a collection of settings that are applied to all API requests made when using its credentials. They are intended to be used to separate different use cases, such as if you're using Urlbox on several different domains, or different environments, such as development and production. Each project has its own unique publishable and secret key, which are used to authenticate requests to the API. When you first sign up, Urlbox will generate a project and name it `default`. You can create as many Projects as you need. You can use projects to rotate your API keys if necessary. ## Creating a new Project The current flow is: 1. Open `Settings` and go to the `Projects` page. ![The Urlbox dashboard with the Settings section open on the Projects page.](/docs/projects/projects-settings-overview.png) 2. Click `Add new project`, then enter a name for the new project. ![The create project dialog in the Urlbox dashboard.](/docs/projects/projects-create-modal.png) 3. After creation, Urlbox opens the new project's settings so you can copy credentials and configure project-specific options. ![The settings page for a newly created project in the Urlbox dashboard.](/docs/projects/projects-new-project-settings.png) ## Project settings From within the dashboard settings menu, you can access the settings for each individual project. ### API Credentials Each project has a publishable key, a secret key, and a webhook secret. Use the publishable key in [render links](https://urlbox.com/docs/render-links.md), the secret key for [authenticated API requests](https://urlbox.com/docs/authenticated-requests.md), and the webhook secret to [verify webhook signatures](https://urlbox.com/docs/webhooks.md#verify-webhook). ### Force Secure Render Links This setting will force all API requests to use secure render links, and will reject any requests from render links without an auth token with a 401 status code. Read more in the [render links documentation](https://urlbox.com/docs/render-links.md). ### S3-Compatible Storage Configuration Each project can store one S3-compatible storage configuration. When you enable [`use_s3`](https://urlbox.com/docs/options.md#use_s3) on a request, Urlbox will upload the render to that project's configured bucket instead of using the default response flow. See the [S3 guide](https://urlbox.com/docs/guides/s3.md) and the storage setup docs such as [Configure S3](https://urlbox.com/docs/storage/configure-s3.md) for more detail. ### Azure Blob Storage Configuration You can also configure Azure Blob Storage at the project level. This is useful if you want renders for one project to go directly to an Azure container you control. For the full setup flow and request examples including `use_azure` and `azure_path`, see [How to Save Automated Screenshots to Azure Blob Storage](https://urlbox.com/save-screenshots-azure-blob-storage.md). ### Default Project Options This section lets you store default render options on the project itself. Those defaults are applied to every request made with the project's credentials, and any request-specific options will override them. This is especially useful for sensitive settings you do not want exposed in public render links, such as headers, cookies, authorization, or login/session values. See the main [options reference](https://urlbox.com/docs/options.md) and the guide on [rendering behind login](https://urlbox.com/docs/guides/rendering-behind-login.md). ### Proxy Configuration You can save a project-level proxy here, then enable it per request with [`use_proxy`](https://urlbox.com/docs/options.md#use_proxy). This keeps the proxy URL out of public render links and lets multiple requests share the same configuration. See the [proxy guide](https://urlbox.com/docs/guides/proxies.md) and the [`proxy`](https://urlbox.com/docs/options.md#proxy) / [`use_proxy`](https://urlbox.com/docs/options.md#use_proxy) option docs. ### LLM Configuration This section stores project-level LLM credentials and defaults for screenshot analysis and extraction workflows. Once configured, you can turn it on in requests with [`use_llm`](https://urlbox.com/docs/options.md#use_llm) and related LLM options. See the [LLM options reference](https://urlbox.com/docs/options.md#use_llm) for the supported providers and request parameters. ### Engine Version You can choose which rendering engine version this project should use by default. This is useful when you want one project pinned to a more conservative version while testing newer behavior in another. See [`engine_version`](https://urlbox.com/docs/options.md#engine_version) for the request-level equivalent. ### Rename Project You can give each project a name so that it is easier to identify in the dashboard. ### Project Status It is possible to disable a project temporarily, which will reject all API requests made with the keys for that project until you enable it again. This can be useful if you suspect that your account is being used by an unauthorized user, your credentials have been leaked, or a misconfiguration is causing problems. ### Delete Project A project can be deleted if it is not used any longer. All API requests using the projects credentials will fail once a project is deleted. There is no way to undo this action. ## Using a Project ### with render links To use a project with render links insert the publishable key of the project into the render link, and use the secret key to generate the HMAC-SHA256 token. ### with REST API To use a project with the REST API, pass the secret key as the Bearer token in the `Authorization` request header. ### with webhooks When using a `webhook_url` in your request, the project's webhook secret can be used to [verify the webhook](https://urlbox.com/docs/webhooks.md#verify-webhook) request is coming from Urlbox. --- # Rate Limits > Source: https://urlbox.com/docs/api/rate-limits Last updated: 2026-07-31 --- The api is rate limited to prevent abuse and ensure stability. The rate limit is dependent on your current plan and gives you a certain number of requests per minute. Requests can be made in parallel, but the total number of requests per minute must not exceed the limit. For every request you make, you will receive the following rate limiting headers: ```http x-ratelimit-limit: 250 x-ratelimit-remaining: 249 x-ratelimit-reset: 1695661076 x-ratelimit-resetdate: Mon, 25 Sep 2023 16:57:56 GMT ``` - `x-ratelimit-limit` - The maximum number of requests you can make per minute. - `x-ratelimit-remaining` - The number of requests remaining in the current rate limit window. - `x-ratelimit-reset` - The time at which the current rate limit window resets in epoch seconds. - `x-ratelimit-resetdate` - The time at which the current rate limit window resets. ## When the rate limit is hit If you exceed this limit, you will receive a 429 status code for your next request. If the rate limit is hit, you will also receive a `Retry-After` header which indicates the number of seconds to wait before making another request. --- # REST API vs Render Links > Explaining differences between generating renders using render links and via the REST API Source: https://urlbox.com/docs/api/rest-api-vs-render-links Last updated: 2026-07-31 --- Renders can be generated with Urlbox in two main ways, directly through render links or through calling endpoints on the REST API. Here we'll call out some of the differences between the two methods. ## Render Links Render links are a specific URL format that contains your api key, an auth token, an output format followed by a query string of url-encoded options. [https://api.urlbox.com/v1/ca482d7e-9417-4569-90fe-80f7c5e1c781/d61624d9b0e0a4ba3cadf90805806c38a6e4518a/png?url=apple.com](https://api.urlbox.com/v1/ca482d7e-9417-4569-90fe-80f7c5e1c781/d61624d9b0e0a4ba3cadf90805806c38a6e4518a/png?url=apple.com) The main advantage of using render links is that you can embed them right inside an `<img>` tag on your page or in an email, or anywhere that an image can be rendered. Render links are also great for: - Embedding screenshots in emails - Embedding screenshots in slack messages, tweets, etc. - Embedding screenshots in your HTML for example, Open Graph tags. - Quick sharing of a urlbox request with all of the options in one string. The typical workflow is: 1. The render link is generated on the server using the server side language of your choice. We have [example code](https://urlbox.com/docs/examplecode.md) to help with this step in various languages. 2. The render link is then embedded in a HTML template (or email template) and sent to the browser. 3. When the page gets loaded by a users browser.. 4. If the render is already cached in our CDN, it will be returned immediately. 5. Otherwise, the API will be called and a fresh screenshot or render will be generated. If you're using a frontend framework such as React, Svelt, Vue or Angular, it's recommended to have a server-side component that generates the render link and passes it back to your frontend, as you don't want to leak your secret key in the browser. Meta frameworks like Next.js, Remix, Nuxt.js and SvelteKit make adding a server function like this very easy. ### Caching of render links Render links are cached for 30 days. This means that if you generate a render link for a given URL and options, the next time you generate a render link for the same URL and options, it will be returned immediately from our cache. Once the cache expires, the next time the render link is requested, a fresh render will be generated. Requests to cached render links do not count against your monthly quota. ### Changing the expiry of render links It's possible to change the duration that we cache the render links for. You can do that by passing in the number of seconds into the [`ttl`](https://urlbox.com/docs/options.md#ttl) option. (ttl stands for time to live and is a common term in caching). For example, if you wanted to cache the render link for 1 day, you would pass in a `ttl` of `86400` seconds. ### Changing the response type By default the response type of a render link is going to be the binary data of the render itself, so that an img or meta tag can render it. If you prefer to get a JSON response similar to the REST API, you can pass in the `response_type` option and set it to `json`. ### Busting the cache The cache key is based on the query options combined with the format in the render link. The order of query options doesn't matter for caching purposes. If you want to get up to date screenshots before the cache expires, one way to bust the cache is to use the `unique` parameter by passing in a unique string, such as a timestamp. ### Forcing a fresh screenshot If you want to force a fresh screenshot, you can pass in the [`force`](https://urlbox.com/docs/options.md#force) parameter with a value of `true`. We don't recommend using this option when embedding the URL's directly in your HTML as it will cause the screenshot to be regenerated every time the page is loaded. ### Deleting a cached render link It's possible to remove a cached render link from our cache by sending a `DELETE` to the same URL. This will remove it both from our cache and also expire it in cloudflares CDN. ### Deduplication of render links Because the typical use case for render links is to embed them in HTML, if there are two or more requests made for the same combination of options, we will only generate one screenshot and duplicate, in-flight requests will receive a 307 temporary redirect, which will end up receiving the same response as the original request. ### Always Synchronous Render links are always synchronous. You can still use a `webhook_url` in a render link, but it makes more sense to use them with the asynchronous API. You can also call the render link with `HEAD` rather than `GET` if you just want to generate the render but not download it. ### Error handling Error responses will always be returned in JSON format. When using render links embedded in an image tag, it's more difficult to handle errors as the browser will just display a broken image. If you want to make it easier to handle errors, it's better to use the REST API or call the render link directly using a `GET` or `HEAD` request. ### Accessing response headers It's also not easy to access response headers if the render link is embedded in an image tag. If you want to access response headers, it's better to use the REST API or explicitly call the render link with `HEAD` or `GET`. ### URL length Because of various limits on URL length, render links are not a great option for rendering from HTML, or when passing options with large payloads, such as [custom javascript](https://urlbox.com/docs/options.md#js) or [css](https://urlbox.com/docs/options.md#css). For these types of requests it's better to use the REST API. ## API The API is made up of various endpoints that accept a JSON (or form encoded) payload of options that are `POST`ed to them and returns a JSON response with the URL to the render. The API is again intended to be used on the server side, as it uses your projects secret key for authentication in the `Authorization` response header. One advantage of using the API is that you can pass in larger payloads of options, such as custom javascript, or HTML to render. ### Asynchronous or synchronous Depending on the endpoint you call, the API can be used either synchronously (`/v1/render/sync`) or asynchronously (`/v1/render/async`). The synchronous endpoint will return the render in the response, whereas the asynchronous endpoint will return a status URL which can be polled. Webhooks can also be triggered by passing in a `webhook_url` option. ### Caching of API requests API requests are not cached, so every request will generate a fresh render. ### Deduplication of API requests Requests through the API endpoints are not deduplicated, so if you make two requests for the same URL with the same options, two renders will be generated. ### Response format The default response is JSON, but you can also request a binary response by passing in the `response_type` option and setting it to `binary`. ### Response headers Several useful response headers are returned when calling either sync or async endpoints. --- # C# website screenshots > Generate website screenshots with C# Source: https://urlbox.com/docs/examplecode/csharp Last updated: 2026-07-31 --- Below is some sample code to take website screenshots in C#.

Instead of the content you asked for, the render comes back with a CAPTCHA, a "verify you are human" interstitial, an error status like 403 or 429, or a nearly blank page. Because a page still rendered, the request succeeds from Urlbox's point of view, and you end up storing a screenshot of the block page. This guide covers how to detect blocks so that never happens, how to retry them automatically, and how to make renders look less like a bot so they succeed in the first place. ## How blocking works Sites decide a request is a bot using some combination of: - **IP reputation** - requests from datacenter IP ranges are treated with more suspicion than residential connections - **Browser fingerprinting** - automated browsers leak subtle differences from a real user's browser, which detection scripts look for - **Request rate** - too many requests in a short window triggers rate limiting, usually a 429 response - **Geography** - some sites only serve certain countries A blocked render shows up in one of two ways: the page responds with an error status (403 Forbidden and 429 Too Many Requests are the most common), or it responds 200 but serves a challenge page instead of the real content. ## Fail instead of capturing the block page By default, Urlbox captures whatever the page serves, even if the response status was an error. The first line of defence is to tell Urlbox which statuses mean "blocked" so the render fails with a clear error instead: ```json { "url": "https://example.com", "fail_on": ["403", "429", "500"] } ``` [`fail_on`](https://urlbox.com/docs/options.md#fail_on) fails the render when the page's final status matches any of the listed codes. To cover whole ranges, use [`fail_on_4xx`](https://urlbox.com/docs/options.md#fail_on_4xx) or [`fail_on_5xx`](https://urlbox.com/docs/options.md#fail_on_5xx), and exclude codes you consider acceptable with [`fail_on_except`](https://urlbox.com/docs/options.md#fail_on_except). When a `fail_on` condition matches, the render fails with an error code naming the condition (for example `fail_on_4xx`) and the page's status code. If you use [webhooks](https://urlbox.com/docs/webhooks.md), you'll receive a `render.failed` event you can handle in your application, rather than a block-page screenshot you'd have to detect yourself. ## Retry automatically Failing cleanly is good; getting the real content is better. [`retry_on`](https://urlbox.com/docs/options.md#retry_on) re-runs the render automatically when it hits a blocked status: ```json { "url": "https://example.com", "retry_on": ["403", "429"] } ``` Retries use exponential backoff: the delay doubles with each attempt, starting from [`retry_delay_ms`](https://urlbox.com/docs/options.md#retry_delay_ms) (1 second by default). For rate limits, the backoff alone is often enough, since the site just wants you to slow down. By default Urlbox makes up to 3 total attempts; tune this with [`max_retries`](https://urlbox.com/docs/options.md#max_retries) or [`max_attempts`](https://urlbox.com/docs/options.md#max_attempts). Beyond status codes, `retry_on` also accepts `4xx`, `5xx`, the engine conditions `timeout` and `crash`, and the quality condition `small_size` (covered below). If every retry fails, the render fails, so you still get a clear error rather than a block page. If a status appears in both `retry_on` and `fail_on`, Urlbox retries first and only fails after retries are exhausted, so the two options combine naturally: `retry_on` to recover, `fail_on` as the safety net. ## Escalate on retry Stealth and proxied renders are slower than standard ones, so you don't want them on every request. [`retry_with`](https://urlbox.com/docs/options.md#retry_with) changes the render options on retry attempts, letting the first attempt run plain and only escalating for renders that actually got blocked: ```json { "url": "https://example.com", "retry_on": ["403", "429"], "retry_with": { "use_stealth": true } } ``` Pass an array instead to escalate progressively, one rung per retry: ```json { "url": "https://example.com", "retry_on": ["403", "429"], "max_retries": 3, "retry_with": [ { "use_stealth": true }, { "use_stealth": true, "proxy": "user:pass@resi.proxyhost.example.com:9000" } ] } ``` Here the first attempt runs plain, the first retry adds stealth, and later retries add a residential proxy on top. Each retry re-runs the render with that attempt's `retry_with` entry merged over the original options, so anything you don't mention stays the same. See the [`retry_with` reference](https://urlbox.com/docs/options.md#retry_with) for the merging rules and the full list of retry-compatible options. ## Make the browser look less like a bot Two options reduce the automation fingerprints that detection scripts look for: - [`hide_headless`](https://urlbox.com/docs/options.md#hide_headless) is the lightweight option. It patches the fingerprints headless Chrome normally leaks, such as `navigator.webdriver`, missing `chrome` runtime objects, and WebGL vendor strings. Reach for it when a site does light bot-detection. - [`use_stealth`](https://urlbox.com/docs/options.md#use_stealth) is the stronger option. Stealth renders use a patched, real Chrome browser configured to look like a normal user's, which gets past most bot walls and CAPTCHAs. It takes precedence if both are set. Stealth renders are noticeably slower than standard renders, so rather than enabling `use_stealth` as a blanket default, apply it only on retries via `retry_with` as shown above. The [user agent](https://urlbox.com/docs/guides/setting-the-user-agent.md) also plays a part: some sites block outdated or unusual user agent strings, and [`user_agent: "random"`](https://urlbox.com/docs/options.md#user_agent) can help when making many requests to the same site in quick succession. ## Change the outgoing IP with a proxy Sites that block by IP reputation will refuse datacenter traffic no matter how convincing the browser looks. The [`proxy`](https://urlbox.com/docs/options.md#proxy) option routes the request through a proxy server you provide, so it reaches the site from a normal-looking IP instead: ```json { "url": "https://example.com", "proxy": "user:password@proxyhost.example.com:9000" } ``` Residential and mobile proxies work best against IP-based blocking. Urlbox doesn't provide proxies; you bring your own from a provider, and you can store one on your [project](https://urlbox.com/dashboard/projects.md) and enable it with [`use_proxy`](https://urlbox.com/docs/options.md#use_proxy) instead of passing the address on every request. Proxies also solve geography-based blocking, since most providers let you choose the country the request originates from. The [proxies guide](https://urlbox.com/docs/guides/proxies.md) covers providers, proxy types, geolocation, and troubleshooting in depth, including the pattern of escalating through a ladder of proxies with `retry_with`. ## Catch soft blocks that return 200 Some challenge pages respond with a 200 status, so status-based options never trigger. Two ways to catch them: - **Size check**: block pages are usually much smaller than real content. Set [`min_size_bytes`](https://urlbox.com/docs/options.md#min_size_bytes) to a floor below your typical screenshot size and add `small_size` to `retry_on`. A render smaller than the floor is retried, and fails if it never reaches it. - **Selector check**: if a site's challenge page has a known element, pass its selector as [`wait_to_leave`](https://urlbox.com/docs/options.md#wait_to_leave) with [`fail_if_selector_present`](https://urlbox.com/docs/options.md#fail_if_selector_present). Urlbox waits for the element to disappear and fails the render if it's still there, so a challenge that never clears can't produce a "successful" screenshot. ```json { "url": "https://example.com", "retry_on": ["403", "429", "small_size"], "min_size_bytes": 50000, "retry_with": { "use_stealth": true } } ``` ## Putting it together A robust setup for block-prone sites combines all of the above: fail conditions as the safety net, retries to recover, and escalation so the expensive measures only run when needed. ```json { "url": "https://example.com", "fail_on_4xx": true, "retry_on": ["403", "429", "small_size"], "min_size_bytes": 50000, "max_retries": 3, "retry_with": [ { "use_stealth": true }, { "use_stealth": true, "proxy": "user:pass@resi.proxyhost.example.com:9000" } ] } ``` With this request: 1. The first attempt runs plain and fast. Most renders succeed here. 2. If the site blocks it (403, 429, or a suspiciously small screenshot), Urlbox retries with stealth after a short backoff. 3. If that's still blocked, further retries add your residential proxy on top of stealth. 4. If every attempt fails, the render fails with a clear error, and you never store a screenshot of a block page. The retry options ([`retry_on`](https://urlbox.com/docs/options.md#retry_on), [`retry_with`](https://urlbox.com/docs/options.md#retry_with), [`min_size_bytes`](https://urlbox.com/docs/options.md#min_size_bytes)) and [`proxy`](https://urlbox.com/docs/options.md#proxy) are available on the [ultra plan](https://urlbox.com/pricing.md) and above. --- # Taking Screenshots of All Pages on a Website > Learn how to capture screenshots of every webpage on a website using sitemap extractors Source: https://urlbox.com/docs/guides/bulk-website-screenshots Last updated: 2026-07-31 --- A common question we receive is: "Are you able to take screenshots of all webpages on a website in one request?" While Urlbox doesn't natively support bulk website captures in a single request, you can easily achieve this using some automation, or CaptureDeck and a sitemap Extractor. This guide will walk you through the process of capturing screenshots of every page on a website, with both code and no-code solutions. ## Overview The process involves two main steps: 1. **Extract all URLs** from the website using its [sitemap](https://en.wikipedia.org/wiki/Site_map) 2. **Capture screenshots** of all URLs using CaptureDeck (for no-code) or your own automation with Urlbox ## Step 1: Getting the List of URLs Most websites publish a sitemap in XML format that contains all their pages. This sitemap is typically available at `/sitemap.xml` on the website's domain. [Here is ours](https://urlbox.com/sitemap.xml.md). ### Finding the Sitemap Companies often place a link to their sitemap in the footer of their main webpage. Common sitemap locations include: - `https://example.com/sitemap.xml` - `https://example.com/sitemap_index.xml` - `https://example.com/sitemaps.xml` For example, OpenAI's sitemap is available at: `https://openai.com/sitemap.xml` ### Extracting URLs from the Sitemap To convert the XML sitemap into a list of all of the website's URLs, you can use an online tool or do it programmatically. #### Using an Online Tool **[SEOwl Sitemap Extractor](https://www.seowl.co/sitemap-extractor/)** is a free tool that extracts URLs from sitemaps. Paste the sitemap URL into the tool, and it will generate a complete list of all pages on the website. #### Using Node.js (Programmatic) For automation or integration into your workflow, we recommend using the [sitemapper](https://www.npmjs.com/package/sitemapper) package: ```bash npm install sitemapper ``` ```javascript import Sitemapper from 'sitemapper'; const sitemap = new Sitemapper({ url: 'https://example.com/sitemap.xml', timeout: 10000, }); const { sites } = await sitemap.fetch(); console.log(sites); // ['https://example.com/', 'https://example.com/about', 'https://example.com/contact', ...] ``` The `sitemapper` package handles nested sitemaps (sitemap indexes) automatically, so you don't need to worry about parsing multiple sitemap files. You could extend this further by accepting just a website URL and then trying to fetch known sitemap locations until you find it, then pass it into the site-mapper. ## Step 2: Capturing Screenshots Once you have your list of URLs, you have several options for capturing screenshots: ### Option 1: CaptureDeck (No-Code Solution) [CaptureDeck](https://capturedeck.com/) is a no-code tool built on top of Urlbox that's perfect for bulk screenshot captures. It's the fastest way to get screenshots of all the webpages on a website without writing your own code. **Steps:** 1. [Sign up](https://capturedeck.com/users/sign_in) for a CaptureDeck account 2. Create a new "Deck" 3. Paste your list of URLs into the deck 4. Run the capture CaptureDeck will process all URLs and provide you with organised screenshots that you can view in the dashboard or download as a ZIP file. CaptureDeck also allows you to create your own 'presets'. These are combinations of options that aim to take a particular type of screenshot. We have preconfigured social media presets, full page presets, or mobile presets. You can find them in your CaptureDeck team settings. ### Option 2: Urlbox API with Custom Script For more control or integration into existing workflows, you can use the Urlbox API directly. Here's a simple example in JavaScript to process multiple URLs: ```javascript const urls = [ 'https://example.com/page1', 'https://example.com/page2', 'https://example.com/page3' // ... your full list of URLs ]; const URLBOX_SECRET = 'your-urlbox-secret'; async function captureScreenshots(urls) { return Promise.all( urls.map(async (url) => { const response = await fetch('https://api.urlbox.com/v1/render/sync', { method: 'POST', headers: { 'Content-Type': 'application/json', 'Authorization': `Bearer ${URLBOX_SECRET}` }, body: JSON.stringify({ url, full_page: true, format: 'png' }) }); const data = await response.json(); return { url, screenshot: data }; }) ); } captureScreenshots(urls) .then(results => { console.log(`Captured ${results.length} screenshots`); // Process your results here }) .catch(error => { console.error('Error capturing screenshots:', error); }); ``` ## Best Practices ### Rate Limiting When processing large numbers of URLs, be mindful of: - **Rate Limits** - For very large sites (1000+ pages), consider spacing out your requests to avoid rate limiting - **Target site politeness** - Don't overwhelm the target website with too many concurrent requests ### Handling Large Sites For websites with thousands of pages: 1. **Batch processing** - Process URLs in batches to avoid overwhelming your system 2. **Storage** - Consider using S3 or similar cloud storage for organising large numbers of screenshots ## Troubleshooting **Sitemap not found?** - Check `/robots.txt` file which often lists the sitemap location - Look for sitemap references in the website's footer or help pages This method might not always work, as some websites don't include a sitemap. ## Getting Help If you run into any issues or need help processing a particularly large or complex website, don't hesitate to contact our support team. We're happy to help you diagnose your setup and optimise your bulk screenshot workflow. --- # Coming Soon > Source: https://urlbox.com/docs/guides/coming-soon Last updated: 2026-07-31 --- Coming Soon... --- # Urlbox Guides > Guides for using Urlbox in different ways Source: https://urlbox.com/docs/guides Last updated: 2026-07-31 --- --- # Proxies > Learn how to configure a proxy with Urlbox Source: https://urlbox.com/docs/guides/proxies Last updated: 2026-07-31 --- When rendering certain sites, you may be blocked from rendering or scraping the content that they serve. An example of this is when sites are using Cloudflare to protect their site from bots: ![Cloudflare protection](/docs/proxies/cloudflare-block.png) In order to get around these protections, the Urlbox API supports the use of proxies. ## How proxies work When you make a request to the Urlbox API, you can specify a proxy to use. The Urlbox API will then make the request to the target site using the proxy you specified. This has the benefit of making the request appear to come from the IP address of the proxy, rather than from urlbox's data center IP address. This reduces the chance that the target site will be able to detect that the request is coming from the Urlbox API. ## Proxy providers Urlbox does not provide proxies for you to use. Instead, you must bring your own proxy by using a proxy provider. There are many proxy providers available, and you can use any provider that you like. Below are some proxy providers: - [Bright Data](https://brightdata.com?ref=urlbox) - [Smartproxy](https://smartproxy.com?ref=urlbox) - [Proxyrack](https://proxyrack.com?ref=urlbox) - [Oxylabs](https://oxylabs.io?ref=urlbox) - [IP Royal](https://iproyal.com?ref=urlbox) - [IP Burger](https://www.ipburger.com?ref=urlbox) ## Using a proxy with Urlbox Taking brightdata as an example, you can signup for an account there and then create a proxy. They have several solution types and usually the best proxies are web unlockers, residential or 4G / mobile proxies. In this example I've created a proxy using the Web Unlocker solution type, this also gives the following benefits: - Bypass CAPTCHAs, blocks, and, restrictions - Only pay for successful requests - Automated IP address rotation - User emulation & fingerprints If you click on the proxy you created, then go to the `Access parameters` tab, and finally click on the `Check out code and integration examples` button. With the `API` type selected and Language set to `Node.js` you can copy the proxy URL: ![copy proxy URL from brightdata](/docs/proxies/brightdata-proxy-url.png) The proxy URL should look something like: `http://brd-customer-hl_3f08b01c-zone-social_networks:ttpg162fe6e2@brd.superproxy.io:22225` To use this with Urlbox, you can pass it in directly in the request: ```json { "url": "https://www.google.com", "proxy": "http://brd-customer-hl_3f08b01c-zone-social_networks:ttpg162fe6e2@brd.superproxy.io:22225" } ``` Now urlbox will make the request to the target URL using the proxy you specified. ## Escalating through proxies on retry Proxies add cost and latency, so ideally most of your renders shouldn't use one. If a site only blocks you some of the time (rate limiting with 429 responses, or bot detection returning 403s), you can combine [`retry_on`](https://urlbox.com/docs/options.md#retry_on) and [`retry_with`](https://urlbox.com/docs/options.md#retry_with) to attempt each render without a proxy first, and only route through your proxies when the render actually gets blocked. Say you have three proxies available, from cheapest to most expensive. In your JSON POST body: ```json { "url": "https://example.com", "retry_on": ["403", "429"], "max_retries": 3, "retry_delay_ms": 2000, "retry_with": [ { "proxy": "user:pass@dc1.cheapproxy.example.com:8080" }, { "proxy": "user:pass@isp.midproxy.example.com:8080" }, { "proxy": "user:pass@resi.premiumproxy.example.com:9000" } ] } ``` The first attempt runs with no proxy at all. If the page responds with a 403 or 429, Urlbox retries automatically with exponential backoff (the wait doubles each time, starting from `retry_delay_ms`; the backoff alone often gets you past rate limits), and each retry moves down your list: the cheap datacenter proxy first, then the mid-tier one, then the residential one. Most renders succeed on the first attempt or the cheap rung, so the expensive proxy bandwidth is only spent on the renders that need it. If the unproxied attempt nearly always fails for a particular site, set your cheapest proxy as the top-level `proxy` option instead, and keep `retry_with` for the upgrades. A couple of options that combine well with this pattern: [`use_stealth`](https://urlbox.com/docs/options.md#use_stealth) turns on Urlbox's anti-detection measures, and if a blocked page comes back as a 200 rather than an error status, [`retry_on: "small_size"`](https://urlbox.com/docs/options.md#retry_on) together with [`min_size_bytes`](https://urlbox.com/docs/options.md#min_size_bytes) catches suspiciously small screenshots. ## Solving ERR\_TUNNEL\_CONNECTION\_FAILED error If you are using a proxy and you get an error like `ERR_TUNNEL_CONNECTION_FAILED` then it is likely that the proxy you are using is blocking requests to certain domains. When using bright data residential proxies, some domains such as `linkedin.com` are blocked, unless you go through their full verification process. 1. If the `url` you're sending to Urlbox begins with `https://`, try changing this to `http://` instead, and see if there is any extra message. 2. For example, accessing `https://linkedin.com/` with an unverified residential proxy will give the `ERR_TUNNEL_CONNECTION_FAILED` error. However, if you change this to `http://linkedin.com/` you will get a more helpful error message: `forbidden requests to this domain are blocked using proxy networks, please get access via a web unlocker zone or IDE tools, or contact your account manager to assist` 3. This means that you either go through their full verification process, or you use a different proxy zone to access the specific domain. ### Check proxy connection from command line You can check whether the proxy works directly from your terminal, for example, here is a request to `https://linkedin.com` using a proxy with curl: ```shell curl --proxy brd.superproxy.io:22225 --proxy-user brd-customer-hl_2f08d01c-zone-residential:password -k "https://linkedin.com" curl: (56) CONNECT tunnel failed, response 403 ``` and here is the same request using `http://` instead of `https://` ```shell curl --proxy brd.superproxy.io:22225 --proxy-user brd-customer-hl_2f08d01c-zone-residential:password "http://linkedin.com" Forbidden: requests to this domain are blocked using the proxy networks, please get access via a Web unlocker zone or IDE tools, or contact your account manager to assist% ``` switching to a web unlocker type of proxy, the request works: ```shell curl -I --proxy brd.superproxy.io:22225 --proxy-user brd-customer-hl_2f08d01c-zone-social_networks:password -k "https://linkedin.com" HTTP/1.1 200 OK ``` ### Check proxy blacklist and whitelist settings You should also check in the proxies settings page that you are not accidentally blocking or whitelisting any IP's from accessing the proxy. Urlbox's IP addresses are dynamic and subject to change, so we can't share a list to whitelist. If you require fixed IP addresses, please [speak to us](mailto:support@urlbox.com). ### Check proxy providers status page As a last resort, it is often worth checking the status page of the proxy provider you are using, as they may be experiencing issues. For example, bright datas status page is here: [https://brightdata.com/network-status](https://brightdata.com/network-status) ## Geolocation Sometimes it is also beneficial to have an IP address from a specific country. For example, if you are rendering a site that has different content for different countries, you may want to use a proxy from that country. A lot of proxy providers allow you to target locations down to country and city level, even the zipcode. You can also use proxies that originate from certain ASN's. An example using brightdata again, you can specify the city and country as part of the proxy URL. Here's an example of a proxy that would originate from New York, USA: `brd-customer-{YOUR_CUSTOMER_ID}-zone-{YOUR_ZONE}-country-us-city-newyork` ## Proxy gotchas When using proxies along side Urlbox, expect slower render times, as the request has to go through the proxy before it reaches the target site. When using residential proxies, there will be a higher change of request failures, as some devices may suddenly go offline, or the connection to the proxy is not stable. Some domains are still blocked by proxy providers, especially high value scraping targets such as linkedin, amazon etc, so you may need to go through their verification process to get access to those domains, or use a web unlocker zone. Sites may still block proxies, so you may need to try a few different providers and proxy types before you find one that works for you. ## Extraneous requests It is also worth noting that when using a proxy, you may see some extraneous requests to domains such as `accounts.google.com` in your proxy request logs. This is because when booting the headless chrome browser, chrome will make some requests to google domains to check for account logins, or updates. We try to reduce as many of these extraneous requests as possible, but there are some that are not possible to remove. You can use the various [`block_*` options](https://urlbox.com/docs/options.md#blocking-options) to block many of these requests from happening. ### Blocking requests by domain You can use the [`block_urls`](https://urlbox.com/docs/options.md#block_urls) to block specific domains from being requested. ```json { "url": "https://urlbox.com", "proxy": "http://brd-customer-hl_3f08b01c-zone-social_networks:ttpg162fe6e2@brd.superproxy.io:22225", "block_urls": [ "*facebook*", "*fullstory*", "*crisp*", "*intercom*", "*getdrip*", "*olark*", "*optimizely.com*", "https://shift.com/images/*", "*segment.com*", "*.optimizely.com", "everesttech.net", "userzoom.com", "doubleclick.net", "googleadservices.com", "adservice.google.com/*", "connect.facebook.com", "connect.facebook.net", "sp.analytics.yahoo.com" ] } ``` ### Block requests by resource type You can also block all requests of a certain resource type, to reduce the amount of bandwidth used by the proxy. For example, you can [block images](https://urlbox.com/docs/options.md#block_images) and [fonts](https://urlbox.com/docs/options.md#block_fonts) using the following options: ```json { "url": "https://urlbox.com", "proxy": "http://brd-customer-hl_3f08b01c-zone-social_networks:ttpg162fe6e2@brd.superproxy.io:22225", "block_images": true, "block_fonts": true } ``` --- # Rendering Behind a Login > How to screenshot pages that require you to be logged in, using session cookies or auth headers Source: https://urlbox.com/docs/guides/rendering-behind-login Last updated: 2026-07-31 --- Every Urlbox render runs in a fresh browser with no history, no cookies, and no saved sessions. Point it at a page that requires a login and you'll get a screenshot of the login form, not the content behind it. To render the logged-in view, you need to give the render browser the same credentials your own browser presents. For most sites that means session cookies; for APIs and some apps it means an `Authorization` header. ## How site logins work When you log in to a site, the server sets one or more **session cookies** in your browser. On every subsequent request, your browser sends those cookies back, and that is what keeps you logged in - the server doesn't remember your browser, it recognises the cookies. So the trick is: 1. Figure out **which cookie or cookies** are actually keeping you logged in 2. **Grab their values** from your browser 3. Pass them to Urlbox with the [`cookie`](https://urlbox.com/docs/options.md#cookie) option The render browser then sends the same cookies to the site, and the site serves it the same logged-in pages it would serve you. ## Finding the session cookies Open the site while logged in, then open your browser's DevTools and go to **Application → Cookies** (Chrome/Edge) or **Storage → Cookies** (Firefox) and select the site's domain. Sites often set many cookies, and most of them are analytics or preferences, not authentication. Things that help narrow it down: - Session cookies usually have names like `session`, `sessionid`, `sid`, `PHPSESSID`, `JSESSIONID`, `connect.sid`, `_<framework>_session`, or `__Secure-`/`__Host-` prefixed names - They're usually marked `HttpOnly` and `Secure` - Their values are long opaque strings or tokens, not readable words To confirm you've found the right ones, delete every other cookie for the domain in DevTools and reload: if you're still logged in, the cookies you kept are the ones you need. (Or do the reverse: delete a suspected session cookie and check that you get logged out.) ## Passing cookies to Urlbox Pass each cookie as a `name=value` string with the [`cookie`](https://urlbox.com/docs/options.md#cookie) option. Multiple cookies go in an array: ```json { "url": "https://example.com/account", "cookie": [ "session_id=eyJhbGciOiJIUzI1NiIs...", "csrf_token=b1946ac92492d234" ] } ``` You can also set cookie attributes such as `Domain`, `Path`, `HttpOnly` and `SameSite` - for example `session_id=abc123;Domain=.example.com` if the site expects the cookie on subdomains too. Urlbox will now be effectively logged in as the user those session cookies were created for. ## The security trade-off (read this) A session cookie **is** your login. Anyone who has it can act as that user until the session expires or is revoked - which makes sharing session cookies with any third party over the internet essentially similar to sharing your password. Before doing this, understand what you're accepting: - **Use a dedicated account.** Create a separate account with the minimum access needed for the pages you want to render, and share that account's session, never your own. - **Send cookies in a POST body, not a URL.** Query-string render links containing session cookies can end up in browser history, server logs, and analytics. Use JSON POST requests to the API for anything sensitive - or better, keep the cookies out of the request entirely with default project options (next section). - **Sessions usually expire - but don't rely on it.** Most sites expire sessions after some period, which limits the damage window. But some setups never do: sites that put a JWT in a cookie and don't track sessions server-side often have **no way to revoke a token at all** - logging out in your own browser deletes your copy of the cookie but does nothing to the copy you shared. Check how the site behaves before assuming expiry protects you. - **Rotate deliberately.** When you stop using a session for rendering, log that account out everywhere (most sites invalidate the session server-side) or change its password. ## Keep the credentials out of the request entirely Rather than sending session cookies with every request, you can store them once as **Default Project Options** in your [project settings](https://urlbox.com/dashboard/projects.md). Default options are applied to every request made with that project's API key, and request-specific options override them - see the [projects docs](https://urlbox.com/docs/api/projects.md) for how they work. For logins this has a real security benefit: the sensitive values never appear in the request at all - not in a render link's query string, and not in the JSON you POST - so they can't leak through browser history, server logs, or the pages that embed your render links. Urlbox encrypts the stored values and adds them to the request server-side when it receives it. This is the recommended home for `cookie`, `header` and `authorization` values: put the session cookie in the project's default options, and your actual requests stay free of secrets. ## Alternatives to session cookies **`Authorization` header.** APIs, and some apps, authenticate with an `Authorization` header instead of cookies. The [`authorization`](https://urlbox.com/docs/options.md#authorization) option sets it directly: ```json { "url": "https://api.example.com/dashboard", "authorization": "Bearer my_bearer_token" } ``` This also handles pages protected by HTTP Basic auth (`"authorization": "Basic base64credentials"`). For sites that use a custom auth header such as `X-API-Key`, use the [`header`](https://urlbox.com/docs/options.md#header) option instead. **Tokens in localStorage or sessionStorage.** Some single-page apps keep the auth token in web storage rather than a cookie (not a pattern we'd recommend building, since any JavaScript on the page can read the token, but plenty of sites do it). There's no direct Urlbox option for seeding web storage, and injecting it with the [`js`](https://urlbox.com/docs/options.md#js) option is fragile because your script runs after the app has already booted unauthenticated. In practice these apps usually *send* the stored token as an `Authorization` header on their API calls, so extracting the token from **Application → Local Storage** in DevTools and passing it via the `authorization` option often works. If it doesn't for your site, [get in touch](mailto:support@urlbox.com) and we'll help. ## Detecting expired sessions When the session eventually expires, your renders won't error - they'll quietly start capturing the login page instead. Make that failure loud: pass a selector that only exists when logged in as [`wait_for`](https://urlbox.com/docs/options.md#wait_for) with [`fail_if_selector_missing`](https://urlbox.com/docs/options.md#fail_if_selector_missing): ```json { "url": "https://example.com/account", "cookie": ["session_id=eyJhbGciOiJIUzI1NiIs..."], "wait_for": "#account-menu", "fail_if_selector_missing": true } ``` Now an expired session fails the render with a clear error (and a `render.failed` [webhook event](https://urlbox.com/docs/webhooks.md) if you use webhooks), telling you it's time to refresh the cookies, instead of silently filling your storage with screenshots of a login form. --- # Rendering Local URLs > How to render sites running on localhost or a private network by exposing them through a tunnel Source: https://urlbox.com/docs/guides/rendering-local-urls Last updated: 2026-07-31 --- Urlbox renders pages from our cloud infrastructure, so the URL you pass has to be reachable from the public internet. A URL like `http://localhost:3000` or a private LAN address won't work - `localhost` would resolve to the render server itself, not your machine. To render a site running on your own machine or inside a private network, give it a temporary public URL with a tunnel. ## Cloudflare Tunnel [Cloudflare Tunnel](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/) is free, and its [quick tunnels](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/do-more-with-tunnels/trycloudflare/) don't even require an account (Cloudflare intends them for exactly this kind of testing and development use): ```shell cloudflared tunnel --url http://localhost:3000 ``` This prints a random `https://<something>.trycloudflare.com` URL that forwards to your local server. Pass that URL to Urlbox: ```json { "url": "https://your-tunnel.trycloudflare.com/some-page" } ``` If you want a stable hostname that survives restarts (useful for webhooks and repeated test runs), create a named tunnel on a domain you manage on Cloudflare - also free on every plan. ## ngrok [ngrok](https://ngrok.com) is the best-known tunnelling tool: ```shell ngrok http 3000 ``` It prints a public `https://<id>.ngrok-free.app` URL forwarding to your local port. The free tier gives you a random URL per session; paid plans offer stable subdomains. ## Other options Any tool that gives your local server a public HTTPS URL works the same way: - [Tailscale Funnel](https://tailscale.com/kb/1223/funnel) - expose a port from your tailnet to the internet - [localtunnel](https://github.com/localtunnel/localtunnel) or `ssh -R` based services like [localhost.run](https://localhost.run) - quick, no-install options - **VS Code port forwarding** - the built-in Ports panel can make a forwarded port public Alternatively, sidestep the tunnel entirely: - **Preview deployments** - if your project deploys previews (Vercel, Netlify, Cloudflare Pages), render the preview URL instead of your local server - **Raw HTML** - if what you really want is to render markup you have locally rather than a running app, pass it directly with the [`html`](https://urlbox.com/docs/options.md#html) option and skip the server completely ## Securing the tunnel A tunnel URL is public: anyone who discovers it can browse your dev server. Random tunnel URLs are hard to guess, but for anything sensitive, put auth on it and pass the credentials in the render request: - **HTTP Basic auth** on your dev server or tunnel, with the credentials passed via the [`authorization`](https://urlbox.com/docs/options.md#authorization) option: `"authorization": "Basic base64credentials"` (ngrok can enforce this itself with `ngrok http 3000 --basic-auth "user:password"`) - **A secret header** your dev server checks, passed via the [`header`](https://urlbox.com/docs/options.md#header) option: `"header": "X-Dev-Secret=some-long-random-value"` Allowlisting Urlbox's IP addresses isn't practical: they are dynamic and subject to change, so header-based auth is the way to lock a tunnel down. If you do require fixed IP addresses, please [speak to us](mailto:support@urlbox.com). Close the tunnel when you're done rendering. --- # Saving to S3 Compatible Storage > Save your screenshots, PDFs and other renders to your own S3-Compatible storage from Urlbox Source: https://urlbox.com/docs/guides/s3 Last updated: 2026-07-31 --- By default, Urlbox's rendering service will save your renders to our own cloud storage. These renders will expire after 30 days. When using render links to call the API, you can rely on the urlbox cache for 30 days to serve your renders, after 30 days the cache will expire and the render will be regenerated the next time the render link is requested. If you would like a more permanent way to store your renders, configuring your project to save to S3, or an S3-compatible service is a great option. Please see the guides below for more information on how to configure s3 and other services with your Urlbox project: - [Amazon S3](https://urlbox.com/docs/storage/configure-s3.md) - [Amazon S3 (private)](https://urlbox.com/docs/storage/configure-s3-private.md) - [Google Cloud Storage](https://urlbox.com/docs/storage/configure-google-cloud-storage.md) - [Cloudflare R2](https://urlbox.com/docs/storage/configure-cloudflare-r2.md) - [DigitalOcean Spaces](https://urlbox.com/docs/storage/configure-digitalocean-spaces.md) - [Backblaze B2](https://urlbox.com/docs/storage/configure-backblaze-b2.md) (More provider guides coming soon - configure the S3 endpoint to the provider's endpoint to use with Urlbox) ## Telling Urlbox to use your S3 bucket Once you have configured a bucket and added the credentials to your project, you need to tell Urlbox to use it. You can do this by passing in the option [`use_s3`](https://urlbox.com/docs/options.md#use_s3) and set it to true. This will tell Urlbox to save the render to the bucket configured on your project instead of Urlbox's storage. When using render links, the render from your bucket will be served by Urlbox's cache for 30 days, after which the cache will expire and the render will be regenerated the next time the render link is requested. When using the API, the `renderUrl` will be a direct link to the render in your bucket. Here's an example using an S3 bucket called `screenshots-demo` and an [`s3_path`](https://urlbox.com/docs/options.md#s3_path) of `screenshots/urlbox/google`. Note that the `renderUrl` is now pointing directly to the file inside the bucket. ```json { "url": "https://www.google.com", "s3_path": "screenshots/urlbox/google", "use_s3": true } ``` ```json { "renderId": "8a83126e-7eb8-442d-8943-86ac953d3017", "status": "succeeded", "renderUrl": "https://screenshots-demo.s3.amazonaws.com/screenshots/urlbox/google.png", "size": 35428, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299 } ``` ## Configuring where Urlbox saves renders in your bucket You can configure where Urlbox will save the renders in your bucket, by setting the [`s3_path`](https://urlbox.com/docs/options.md#s3_path) option. This will be the path to the file in your bucket, and should include subdirectories and the final name. For example if you want to save the render as `screenshot-1.png` inside the `screenshots/urlbox` folder, you would set the `s3_path` option to `screenshots/urlbox/screenshot-1`. ## Other storage options You can override the bucket name to save to on each request, by setting the [`s3_bucket`](https://urlbox.com/docs/options.md#s3_bucket). You will of course need to ensure that the credentials configured also have the required permissions to save to this bucket. You can tell urlbox not to add the file format suffix (e.g. `.png`) to the file in your bucket by setting the [`no_suffix`](https://urlbox.com/docs/options.md#no_suffix) option to true. If necessary you can also set the region of your bucket by passing in [`s3_region`](https://urlbox.com/docs/options.md#s3_region) option. It's also possible to override the configured S3 endpoint per request by sending in the [`s3_endpoint`](https://urlbox.com/docs/options.md#s3_endpoint) option on a request. ## Private bucket mode When a private bucket is configured for your project, Urlbox will use the bucket for storing renders only. When using render links with a private bucket, Urlbox will no longer try to serve the renders directly, and just return a JSON response. --- # Sandbox > The Urlbox sandbox is a place for you to play around with the various options available in the API before coding your integration. Source: https://urlbox.com/docs/guides/sandbox Last updated: 2026-07-31 --- The [sandbox](https://urlbox.com/dashboard/screenshot.md) lets you construct render requests for all of our output formats and see the results. It's a great way to experiment with the various options available in the API before coding your integration. ## How to use the sandbox Go to the sandbox from within your dashboard, choose the input you want to use (URL or HTML), and select the output format you want to render. You can then configure the various options available for that output format and when you're ready you can click `Render` to see the result. The sandbox also shows you the generated render link that you can use to make the same request from your own code, and also the various options in JSON format which you can copy/paste. Since the sandbox is connected to your account, requests made in the sandbox will count towards your monthly quota. ## Loading options from a render When you have a request that has a lot of different options embedded in it, and you want to test it in the sandbox, it can be quite a pain to manually go in and configure all of the options. There is a way to paste in a long render link into the sandbox and have it automatically load up all of the options for you. Press the `Load from url...` button and paste in the render link you want to load the options from (you can also just paste in the query string portion). Check that the options look correct in the preview area, and then click `Load` to load those options into the sandbox. ## Loading options from JSON The same can also be done if your options are already in JSON format. Click the `Load from url...` button and paste in the JSON options you want to load. Check that the options are correct in the preview area, and then click `Load` to load those options into the sandbox. --- # Setting the User Agent > How to override the default user agent Source: https://urlbox.com/docs/guides/setting-the-user-agent Last updated: 2026-07-31 --- The [user agent](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/User-Agent) is another request header that the Urlbox browser sends when visiting a URL. It is sometimes used by sites to determine what type of device is making the request. For example, a site might return a mobile version of the site if the user agent is a mobile device. It can also be used by sites to block requests from bots and for browser fingerprinting. For example, a site might block requests from bots by checking if the user agent is a known bot. This can be done by setting the [`user_agent`](https://urlbox.com/docs/options.md#user-agent) option to something custom when making a request to Urlbox: ```json { "url": "example.com", "user_agent": "My-Custom-User-Agent" } ``` You could emulate certain well known scraping user agent strings like facebook: ```json { "url": "example.com", "user_agent": "facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)" } ``` Other well known user agents include: - `Googlebot` - `Bingbot` - `Slurp` - `DuckDuckBot` - `Baiduspider` - `YandexBot` and others can be found at [https://developers.whatismybrowser.com/useragents/explore/](https://developers.whatismybrowser.com/useragents/explore/) ## Using mobile user agent If you want to use a mobile user agent, you can set the `user_agent` option to `mobile`: ```json { "url": "example.com", "user_agent": "mobile" } ``` ## Using a desktop user agent If you want to use a desktop user agent, you can set the `user_agent` option to `desktop`: ```json { "url": "example.com", "user_agent": "desktop" } ``` ## Using a random user agent If you want to use a random user agent, you can set the `user_agent` option to `random`: ```json { "url": "example.com", "user_agent": "random" } ``` Urlbox will cycle through valid user agents for each request. This can be useful for evading detection when making many requests in quick succession to the same website. --- # Side Renders > Generate extra artifacts - HTML, MHTML, markdown, metadata, extracted content and thumbnails - from the same page load as your main render Source: https://urlbox.com/docs/guides/side-renders Last updated: 2026-07-31 --- When Urlbox renders a page, it can generate more than just the main screenshot, PDF or video. Side renders are extra artifacts captured from the **same page load** as your main render - a markdown conversion of the page, its rendered HTML, page metadata, extracted content like headings, tables and links, resized thumbnails of the screenshot itself, and an MHTML snapshot. Because side renders are produced while the page is already loaded, they don't trigger a second render. You get multiple outputs from a single request, without paying the render time of loading the page twice. Each side render is saved alongside the main render and returned as an extra field in the JSON response - so use the API (which returns JSON by default), or add [`response_type=json`](https://urlbox.com/docs/options.md#response_type) to a render link, to see them. ## Rendering markdown and HTML alongside a screenshot The [`save_markdown`](https://urlbox.com/docs/options.md#save_markdown) and [`save_html`](https://urlbox.com/docs/options.md#save_html) options save an extra text copy of the page in one request - a screenshot for humans and machine-readable content for everything else: - [`save_markdown`](https://urlbox.com/docs/options.md#save_markdown) converts the rendered page to markdown - ideal when you want a screenshot for humans and an LLM-friendly text version of the same page in one request. - [`save_html`](https://urlbox.com/docs/options.md#save_html) saves the page's rendered HTML - captured from the live DOM after the page has finished loading, so it includes any changes made by javascript. ```json { "url": "https://urlbox.com", "save_markdown": true, "save_html": true } ``` The response gains a `markdownUrl` and `htmlUrl` field for each artifact you requested: ```json { "renderUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps.png", "size": 258923, "renderTime": 4213, "queueTime": 165, "markdownUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps.md", "htmlUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps.html" } ``` If you only want markdown or HTML and no screenshot, you can make it the main render instead by setting [`format`](https://urlbox.com/docs/options.md#format) to `md` or `html`. ## Metadata and extracted content Urlbox can extract structured information from the page while rendering it. ### Page metadata Setting [`save_metadata=true`](https://urlbox.com/docs/options.md#save_metadata) extracts the page's metadata: title, description, author, canonical URL, open graph tags, twitter card tags and other meta tags, along with the requested and resolved URLs. The metadata is returned inline in the `metadata` field of the JSON response, and also saved as a JSON side render linked from `metadataUrl`: ```json { "url": "https://www.bbc.co.uk", "save_metadata": true } ``` ```json { "renderUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps.png", "size": 194203, "renderTime": 3987, "metadataUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps.json", "metadata": { "title": "BBC Home - Breaking News, World News, US News, Sports ...", "description": "Visit BBC for trusted reporting on the latest world and US news ...", "ogTitle": "BBC Home - Breaking News, World News, US News, Sports ...", "ogImage": [{ "url": "https://static.files.bbci.co.uk/.../bbc.png" }], "urlRequested": "https://www.bbc.co.uk", "urlResolved": "https://www.bbc.co.uk/" } } ``` ### Headings, tables, structured data and links Four more options extract specific content from the page: - [`save_headings`](https://urlbox.com/docs/options.md#save_headings) extracts every heading (`h1`-`h6`) with its level, text and `id`. The response gains a `headingsUrl` field linking to the saved JSON. - [`save_tables`](https://urlbox.com/docs/options.md#save_tables) extracts every HTML `<table>`, with cells organised as rows and columns plus a markdown rendering of each table. The response gains a `tablesUrl` field. - [`save_structured_data`](https://urlbox.com/docs/options.md#save_structured_data) extracts structured data embedded in the page, such as JSON-LD / schema.org markup. The response gains a `structuredDataUrl` field. - [`save_links`](https://urlbox.com/docs/options.md#save_links) extracts every link with its absolute URL and link text, and adds them to the page metadata under `links` (returned inline in `metadata` and saved to `metadataUrl`). ```json { "url": "https://en.wikipedia.org/wiki/Screenshot", "save_headings": true, "save_tables": true, "save_structured_data": true, "save_links": true } ``` ```json { "renderUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps.png", "size": 231882, "renderTime": 5102, "metadataUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps.json", "headingsUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps-headings.json", "tablesUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps-tables.json", "structuredDataUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps-structured-data.json", "metadata": { "title": "Screenshot - Wikipedia", "links": [ { "href": "https://en.wikipedia.org/wiki/Screencast", "text": "Screencast" } ], "urlRequested": "https://en.wikipedia.org/wiki/Screenshot", "urlResolved": "https://en.wikipedia.org/wiki/Screenshot" } } ``` There are also options to record what happened during the render: [`save_cookies`](https://urlbox.com/docs/options.md#save_cookies) saves the cookies set in the browser by the end of the render, and [`save_clicks`](https://urlbox.com/docs/options.md#save_clicks) records which elements Urlbox clicked automatically (for example cookie-banner buttons clicked by [`click_accept`](https://urlbox.com/docs/options.md#click_accept)). Both are added to the page metadata. [`save_headers`](https://urlbox.com/docs/options.md#save_headers) includes the target page's HTTP response headers in the `response` object of the JSON response. ## Thumbnails The [`thumbnails`](https://urlbox.com/docs/options.md#thumbnails) option generates up to 5 resized versions of the main render, from the same captured image. It applies to image formats (`png`, `jpeg`, `webp`, `avif`), and each thumbnail keeps the main render's format. Each thumbnail spec can set: - a `key` (up to 10 characters) to name the thumbnail, - a size: either explicit pixel dimensions (`size`, or `width`/`height`, each between 10 and 2000), or a `preset` relative to the main render's dimensions: `xs` (10%), `sm` (20%), `md` (30%), `lg` (40%), `xl` (50%), `2xl` (60%), `3xl` (70%), `4xl` (80%), `5xl` (90%), or the fractions `1/4`, `1/2` and `3/4`, - how to resize: `fit` (`cover`, `contain`, `fill`, `inside`, `outside`), `position` and a `bg` colour, with the same semantics as [`img_fit`](https://urlbox.com/docs/options.md#img_fit), [`img_position`](https://urlbox.com/docs/options.md#img_position) and [`img_bg`](https://urlbox.com/docs/options.md#img_bg), - a `presigned_url` to upload the thumbnail straight to your own S3 bucket. Because the value is an array of objects, use `thumbnails` with JSON POST requests to the render endpoints: ```json { "url": "https://urlbox.com", "thumbnails": [ { "key": "small", "preset": "sm" }, { "key": "card", "width": 400, "height": 300 } ] } ``` By default the response contains a `thumbnails` **array**, one entry per spec: ```json { "renderUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps.png", "size": 258923, "renderTime": 4213, "thumbnails": [ { "key": "small", "location": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps-small.png", "size": 18332 }, { "key": "card", "location": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps-card.png", "size": 24560 } ] } ``` Set [`thumbnails_object=true`](https://urlbox.com/docs/options.md#thumbnails_object) to get the same results as an **object** keyed by each thumbnail's `key` instead, useful when you want to look thumbnails up by name rather than position: ```json { "renderUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps.png", "size": 258923, "renderTime": 4213, "thumbnails": { "small": { "location": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps-small.png", "size": 18332 }, "card": { "location": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps-card.png", "size": 24560 } } } ``` ## MHTML snapshots If you need a self-contained archive of the page, [`save_mhtml=true`](https://urlbox.com/docs/options.md#save_mhtml) saves an MHTML snapshot alongside the main render. MHTML bundles the page and its resources into a single file that can be opened in a browser for offline viewing. The response gains an `mhtmlUrl` field: ```json { "url": "https://urlbox.com", "save_mhtml": true } ``` ```json { "renderUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps.png", "size": 258923, "renderTime": 4213, "mhtmlUrl": "https://renders.urlbox.com/ub-temp-renders/renders/.../<render-id>_ps.mhtml" } ``` ## Where side renders are stored Side renders are stored exactly like the main render. By default they are saved to Urlbox's own cloud storage and served from our CDN, expiring after 30 days. If you have configured your own S3-compatible storage and set [`use_s3=true`](https://urlbox.com/docs/options.md#use_s3), side renders and thumbnails are saved to your bucket alongside the main render, and the `*Url` fields in the response point at your bucket (or your [`cdn_host`](https://urlbox.com/docs/options.md#cdn_host), if you have set one). See the [saving to S3 guide](https://urlbox.com/docs/guides/s3.md) for how to set this up. ## Billing Side renders don't cost extra render time, since they reuse the page load of the main render. Their file sizes, and the file sizes of any thumbnails, do however count toward the render's total output size, which is part of the credit calculation: one render credit is used per 5MB of file size over the included allowance. In practice most side renders (markdown, HTML, metadata JSON, thumbnails) are small, so a typical request with a handful of side renders still costs a single credit. ## Related options See the [Side Render Options](https://urlbox.com/docs/options.md#side-render-options) section of the options reference for every option covered in this guide. --- # Sync vs Async > Sync vs Async Source: https://urlbox.com/docs/guides/sync-vs-async Last updated: 2026-07-31 --- The Urlbox API can be called in both synchronous and asynchronous modes. Depending on your use case and desired workflow, you may want to choose one method of calling the API over another. With render links the request will always be synchronous. ## Synchronous requests Synchronous means that when calling the API the request will wait for the render to finish generating before returning a response. The render will be returned in this response either as binary data or as a URL to the rendered image depending on how you're calling the API. ### When to use synchronous requests Synchronous requests are useful when you want to get the results back immediately. When you want to call the Urlbox API directly from an `<img>` tag, you can use a [render link](https://urlbox.com/docs/render-links.md) which will always be synchronous and return the binary data by default. It is usually easier to use synchronous requests when integrating with no-code solutions such as Zapier. If your server environment can deal with potentially having many long running connections open at the same time, then synchronous requests might be a good choice. ## Asynchronous requests Asynchronous means that the request will return immediately with a `renderId` and `statusUrl` (if the request passes validation). The `renderId` can be stored and used to retrieve the render at a later time, either by polling the `statusUrl` or by passing in a [`webhook_url`](https://urlbox.com/docs/options.md#webhook_url) to be notified when the render is complete. ### When to use asynchronous requests Asynchronous requests are useful when you want to render a large number of URLs or when the render time is long (such as when rendering a very tall page with [`full_page`](https://urlbox.com/docs/options.md#full_page) set to true). You can fire off the requests, and either poll the status URL's, or wait for your webhook endpoint to be called. --- # Rendering PDFs > How to render PDFs with Urlbox from URL or HTML Source: https://urlbox.com/docs/pdfs/rendering-pdfs Last updated: 2026-07-31 --- To render PDF's with Urlbox, set the format to `pdf` and pass in a URL or HTML and any relevant options. ```json { "url": "https://bbc.co.uk", "format": "pdf" } ``` When rendering PDF's the default is to render the entire website into multiple pages of a PDF document. You can specify a specific page, or page range to render by passing in the `pdf_page_range` option. This option works similar to a typical print dialog in a web browser, for example to print the first page, and then the third to the fifth page, you would pass in `1,3-5`. ```json { "url": "https://bbc.co.uk", "format": "pdf", "pdf_page_range": "1,3-5" } ``` To render the full website into a single page in the PDF document, set `full_page` to true. ```json { "url": "https://bbc.co.uk", "format": "pdf", "full_page": true } ``` ## Render PDF from HTML To render a PDF from some HTML, pass in the `html` option with the HTML you want to render. If the HTML has relative links to images, stylesheets or other resources, you can pass in the `base_url` option to specify the base URL to use for relative links. ```json { "html": "<html><body><h1>Hello World</h1></body></html>", "format": "pdf" } ``` ## Change the PDF page size To change the PDF page size to a predetermined page size, set the [`pdf_page_size`](https://urlbox.com/docs/options.md#pdf_page_size) option. To set the PDF page size to a custom size, set the [`pdf_page_width`](https://urlbox.com/docs/options.md#pdf_page_width) and [`pdf_page_height`](https://urlbox.com/docs/options.md#pdf_page_height) options. ## Change the default stylesheet By default when capturing PDF documents, Urlbox will use the print stylesheet to render the page. Some sites that make use of a print specific stylesheet may appear different on the PDF to how they appear in a web browser. To change the stylesheet to the regular stylesheet, set the [`media`](https://urlbox.com/docs/options.md#media) option to `screen`. ```json { "url": "https://bbc.co.uk", "format": "pdf", "media": "screen" } ``` --- # Screenshot a single element > Screenshot a single element on a web site Source: https://urlbox.com/docs/screenshots/element-screenshots Last updated: 2026-07-31 --- Sometimes you just want to take a screenshot of part of a page. To do this with Urlbox, you can pass the CSS selector of the element you want to screenshot into the [`selector`](https://urlbox.com/docs/options.md#selector) option. ## Example ```json { "url": "example.com", "selector": "#element-to-screenshot" } ``` What is a CSS selector?\ A CSS selector is a way of identifying an element on a web page.\ For example, the CSS selector for the first heading on this page is `h1`.\ You can find out more about CSS selectors [here](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors). ## How to find the CSS selector of the element you want to screenshot The easiest way to find the CSS selector of an element is to use the [Chrome DevTools](https://developers.google.com/web/tools/chrome-devtools). 1. Open Chrome DevTools by right clicking on the element you want to screenshot and selecting "Inspect". 2. In the Elements tab, right click on the element you want to screenshot and select "Copy" > "Copy selector". --- # Full page screenshots > How to take full page screenshots with Urlbox Source: https://urlbox.com/docs/screenshots/full-page-screenshots Last updated: 2026-07-31 --- In order to take full page screenshots, you can set the [`full_page`](https://urlbox.com/docs/options.md#full_page) option to `true` in your API request. ```json { "url": "https://urlbox.com", "full_page": true } ``` ## Skipping the initial scroll By default, Urlbox will scroll to the bottom of the page before taking the screenshot. This is to ensure that any lazy loaded elements are loaded before taking the screenshot, and to determine the final scrollable height of the page before screenshotting. If you want to disable this behaviour, you can set the [`skip_scroll`](https://urlbox.com/docs/options.md#skip_scroll) option to `true`. This should also shave a few seconds off your render time, depending on how tall the website you are rendering is. ```json { "url": "https://urlbox.com", "full_page": true, "skip_scroll": true } ``` ## Setting the full page mode Urlbox has two different modes for taking full page screenshots. The default mode is `stitch` which uses Urlbox's proprietary algorithm to intelligently scroll the page, triggering animations and lazy loaded elements, freezing fixed and sticky elements, detecting 100% height backgrounds, taking multiple screenshot sections and stitching them together. This mode is the most reliable and will work on most websites. It is optimised for accuracy over speed. The second mode is `native` which uses the browser's native screenshot functionality to take a screenshot of the entire page. This mode is faster but may not work well across all websites. It is optimised for speed over accuracy. You can switch between full page modes using the [`full_page_mode`](https://urlbox.com/docs/options.md#full_page_mode) parameter. ```json { "url": "https://www.stripe.com", "full_page": true, "full_page_mode": "native" } ``` ## Stitch and scroll options There are several options that affect the full page algorithm when in `stitch` mode. By default the height of each section is set to 4096px, unless Urlbox detects a strected background, but when a [`height`](https://urlbox.com/docs/options.md#height) is set along with [`full_page`](https://urlbox.com/docs/options.md#full_page), the height will set the browsers viewport height, meaning that the individual screenshot sections will also be capped at the height passed in. The [`scroll_increment`](https://urlbox.com/docs/options.md#scroll_increment) option sets the number of pixels to scroll the page by when taking each screenshot section. The default is 4096px. Sometimes it is necessary to set a smaller scroll incrememnt to trigger certain actions such as animations, or lazy loading elements. The [`scroll_delay`](https://urlbox.com/docs/options.md#scroll_delay) option sets a delay in milliseconds between each scroll. The default is 100ms. This can also be useful for ensuring animations have enough time to complete. The [`max_sections`](https://urlbox.com/docs/options.md#max_sections) option sets the maximum number of screenshot sections to take. The [`max_section_height`](https://urlbox.com/docs/options.md#max_height) option allows control over the height of individual screenshot sections but without setting the viewport height at the same time. ## Viewing the full page sections It's possible to view the individual sections that Urlbox captures when taking a full page screenshot by setting the [`show_seams`](https://urlbox.com/docs/options.md#show_seams) option to `true`. This can be useful for debugging purposes. ## Detecting fixed and sticky elements Because Urlbox scrolls the page and takes multiple screenshot sections, it is possible that fixed or sticky elements such as headers and footers will be captured multiple times, in each section. Urlbox uses heuristics to detect most fixed elements and only captures them once. To disable this behaviour, you can set the [`freeze_fixed`](https://urlbox.com/docs/options.md#freeze_fixed) option to `false`. ## Detecting popups and modals Sometimes by scrolling the page, Urlbox will trigger a popup or modal to appear. You can attempt to hide these by setting the [`hide_cookie_banners`](https://urlbox.com/docs/options.md#hide_cookie_banners) option and [`click_accept`](https://urlbox.com/docs/options.md#click_accept) option to `true`. - `hide_cookie_banners` will attempt to hide cookie banners by setting their display property to `none`, - whereas `click_accept` will attempt to send a click event to the detected accept button on cookie banners. In addition to these settings, you can also enable the adblocker, by setting [`block_ads`](https://urlbox.com/docs/options.md#block_ads) to `true`. There is also the ability to block certain domains from being loaded by the page, by setting the [`block_urls`](https://urlbox.com/docs/options.md##block_urls) option to a comma separated list of domains to block. Wildcards can also be used. ```json { "url": "https://urlbox.com", "full_page": true, "hide_cookie_banners": true, "click_accept": true, "block_ads": true, "block_urls": [ "*.optimizely.com", "everesttech.net", "userzoom.com", "doubleclick.net", "googleadservices.com", "adservice.google.com/*" ] } ``` ## Allowing infinite scroll Sometimes a page will have infinite scroll, meaning that when the page is scrolled to the bottom, more content is added. This can end up in a never ending loop. Urlbox detects infinitely scrolling web pages and sets the maximum sections to 3 by default when this happens. If you want to allow infinite scroll, you can set the [`allow_infinite`](https://urlbox.com/docs/options.md#allow_infinite) option to `true`. ## Detecting 100% height backgrounds Some web pages deploy certain CSS rules to create `100%` or `100vh` height image backgrounds or hero sections, meaning that a backgroud image or hero section will be set to the same height as the browsers viewport, which when taking full page screenshots will be 4096px tall by default. Urlbox detects these scenarios and limits the maximum section height and browser viewport to 1024px when this happens, to avoid the image or section being stretched out of proportion. It is possible to disable this check by setting the [`detect_full_height`](https://urlbox.com/docs/options.md#detect_full_height) option to `false`. ## Setting the max height If you want to limit the height of the full page screenshot, you can set the [`max_height`](https://urlbox.com/docs/options.md#max-height) parameter to the number of pixels you want to limit the screenshot to. ## Setting a scroll offset If you only want to capture the full page screenshot from a certain point, you can set the [`scroll_to`](https://urlbox.com/docs/options.md#scroll-to) parameter to either the number of pixels you want to offset the screenshot from the top of the page, or a CSS selector of an element you would like to start capturing from. ## Horizontally scrolling pages When measuring the page dimensions, Urlbox uses the [`clientWidth`](https://developer.mozilla.org/en-US/docs/Web/API/Element/clientWidth) property of the scrolling element by default. If the page scrolls horizontally, and you want to capture the full width of the page as well as the full height, you can set [`full_width`](https://urlbox.com/docs/options.md#full_width) to `true`. Urlbox will now use the [`scrollWidth`](https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollWidth) property of the scrolling element to determine the width of the page. ## Slicing full page screenshots Very tall full page screenshots can be difficult to analyse with AI vision models, which often downscale or reject large images. Setting [`full_page_slices`](https://urlbox.com/docs/options.md#full_page_slices) to `true` splits the final screenshot into smaller vertical slices, each stored as its own image. ```json { "url": "urlbox.com", "full_page": true, "full_page_slices": true, "response_type": "json" } ``` The JSON response then includes a `slices` array alongside the main `renderUrl`: ```json { "renderUrl": "https://renders.urlbox.com/urlbox1/renders/.../abc123.png", "slices": [ { "index": 0, "offset_y": 0, "width": 1280, "height": 4000, "url": "https://renders.urlbox.com/urlbox1/renders/.../abc123-slice-0.png" }, { "index": 1, "offset_y": 4000, "width": 1280, "height": 2350, "url": "https://renders.urlbox.com/urlbox1/renders/.../abc123-slice-1.png" } ] } ``` Each slice is at most [`full_page_slice_height`](https://urlbox.com/docs/options.md#full_page_slice_height) pixels tall (default `4000`). If the screenshot is shorter than this, a single slice is returned. To give adjacent slices shared context, set [`full_page_slice_overlap_height`](https://urlbox.com/docs/options.md#full_page_slice_overlap_height) to the number of pixels each slice should repeat from the previous one. This means content cut at a slice boundary appears in full in at least one slice. ## Limitations on image size Please bear in mind that there are limitations to the size of images that can be captured. For jpeg, the maximum image dimensions are 65,535 by 65,535pixels. For webP, the maximum image dimensions are 16,383 by 16,383 pixels. It is best to use png format when using the full page option as there are no limitations on image size. --- # Rendering thumbnails > Generate multiple thumbnail images from a single render using the thumbnails option Source: https://urlbox.com/docs/screenshots/thumbnails Last updated: 2026-07-31 --- Urlbox has two different ways to produce a smaller image from a render. Understanding when to use each will help you get the result you want. | Option | Use case | How it works | | ----------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------- | ---------------------------------------------------------------------------------- | | [`thumb_width`](https://urlbox.com/docs/options.md#thumb_width) / [`thumb_height`](https://urlbox.com/docs/options.md#thumb_height) | Resize the **main** screenshot | The image the API returns is itself resized | | [`thumbnails`](https://urlbox.com/docs/options.md#thumbnails) | Generate **separate** thumbnail files | Up to 5 additional images are generated and uploaded alongside the main screenshot | If you just need a smaller version of your screenshot, use `thumb_width` / `thumb_height`. If you need several different sizes, or want thumbnails stored as their own files, use `thumbnails`. ## Basic example with presets The easiest way to create a thumbnail is with a size `preset`, which scales the thumbnail as a percentage of the main screenshot's dimensions: ```json { "url": "https://stripe.com", "thumbnails": [ { "preset": "sm" }, { "preset": "lg" } ] } ``` ### Available presets | Preset | Scale | | ------ | ----- | | `xs` | 10% | | `sm` | 20% | | `md` | 30% | | `lg` | 40% | | `xl` | 50% | | `2xl` | 60% | | `3xl` | 70% | | `4xl` | 80% | | `5xl` | 90% | | `1/4` | 25% | | `1/2` | 50% | | `3/4` | 75% | For example, on a 1280x800 screenshot, `preset: "sm"` (20%) produces a 256x160 thumbnail. ## Custom dimensions Instead of a preset, you can give exact pixel dimensions. `width` and `height` can be set independently, each between 10 and 2000 pixels: ```json { "url": "https://stripe.com", "thumbnails": [ { "width": 200, "height": 150 }, { "width": 400, "height": 300 } ] } ``` ## Square thumbnails Use `size` as a shorthand for equal width and height: ```json { "url": "https://stripe.com", "thumbnails": [ { "size": 100 }, { "size": 200 } ] } ``` ## Fit, position and background Each thumbnail spec can set its own `fit`, `position` and `bg`. If a spec omits one of these, it falls back to the equivalent top-level render option, and finally to a fixed default: | Property | Falls back to | Final default | | ---------- | --------------------------------------------------------------------------------------------------------------------- | ------------- | | `fit` | [`img_fit`](https://urlbox.com/docs/options.md#img_fit) | `cover` | | `position` | [`img_position`](https://urlbox.com/docs/options.md#img_position) | `north` | | `bg` | [`img_bg`](https://urlbox.com/docs/options.md#img_bg), then [`bg_color`](https://urlbox.com/docs/options.md#bg_color) | `black` | `fit` controls how the image is resized to the target dimensions: | Mode | Description | | --------- | -------------------------------------------------------------------------------- | | `cover` | Crops the image to fill the dimensions (default) | | `contain` | Fits the whole image inside the dimensions, may leave a background-filled border | | `fill` | Stretches the image to fill the dimensions exactly | | `inside` | Resizes to fit inside the dimensions, preserving aspect ratio | | `outside` | Resizes to cover the dimensions, preserving aspect ratio | `position` accepts any [`img_position`](https://urlbox.com/docs/options.md#img_position) value, including `attention` and `entropy`, which crop around the most visually interesting or highest-entropy region of the image rather than a fixed edge or corner. When `fit: "contain"` leaves empty space around the image, `bg` fills it: ```json { "url": "https://stripe.com", "thumbnails": [ { "size": 200, "fit": "contain", "bg": "#5F1EE6" } ] } ``` ## Naming thumbnails with key and suffix Each thumbnail spec is given a filename suffix (and, in the JSON response, an identifying `key`) resolved from whichever of these properties is set, in priority order: `key` → `suffix` → `preset` → `size` → `width` → `height` → `"thumb"`. `key` and `suffix` are **not** interchangeable: if both are omitted, the filename falls through to the calculated dimensions and finally to the literal string `thumb`. Setting `key` also determines the property name used to look up this thumbnail when [`thumbnails_object`](https://urlbox.com/docs/options.md#thumbnails_object) is enabled, so prefer `key` over `suffix` whenever you need a stable, predictable identifier. `key` is limited to 10 characters. ```json { "url": "https://stripe.com", "thumbnails": [ { "preset": "sm", "key": "nav" }, { "preset": "lg", "key": "hero" } ] } ``` ## Uploading to your own storage Each thumbnail spec can carry its own `presigned_url` to upload that specific thumbnail directly to a URL you control, instead of Urlbox's own storage. This is useful when different thumbnail sizes need to land in different buckets or paths. See the [storage guides](https://urlbox.com/docs/storage/configure-s3.md) for background on configuring your own storage. ## The query-string form The examples above show a JSON request body, where `thumbnails` is a plain array. Over a `GET` request, the same array is sent as a query string using `qs`-style bracket notation: ``` &thumbnails[0][preset]=md&thumbnails[1][width]=320&thumbnails[1][key]=w320 ``` which is equivalent to the JSON body: ```json { "thumbnails": [{ "preset": "md" }, { "width": 320, "key": "w320" }] } ``` ## Response format By default, [`thumbnails_object`](https://urlbox.com/docs/options.md#thumbnails_object) is `false` and thumbnails come back as an array, each entry carrying its own `key`: ```json { "renderUrl": "https://renders.urlbox.com/.../abc123.png", "thumbnails": [ { "key": "nav", "location": "https://renders.urlbox.com/.../abc123-nav.png", "size": 12345 }, { "key": "hero", "location": "https://renders.urlbox.com/.../abc123-hero.png", "size": 56789 } ] } ``` Setting [`thumbnails_object`](https://urlbox.com/docs/options.md#thumbnails_object) to `true` reshapes this into an object keyed by each thumbnail's `key`/suffix, with `key` omitted from each value since it's now the object's own key: ```json { "url": "https://stripe.com", "thumbnails": [ { "preset": "sm", "key": "small" }, { "preset": "lg", "key": "large" } ], "thumbnails_object": true } ``` ```json { "renderUrl": "https://renders.urlbox.com/.../abc123.png", "thumbnails": { "small": { "location": "https://renders.urlbox.com/.../abc123-small.png", "size": 12345 }, "large": { "location": "https://renders.urlbox.com/.../abc123-large.png", "size": 56789 } } } ``` ## Limits - Maximum of 5 thumbnails per request. - Each `size`, `width` and `height` must be between 10 and 2000 pixels. - `key` is limited to 10 characters. ## Use cases ### Responsive images Generate the handful of sizes a responsive `<img srcset>` needs in one render: ```json { "url": "https://stripe.com", "thumbnails": [ { "width": 320, "key": "mobile" }, { "width": 768, "key": "tablet" }, { "width": 1200, "key": "desktop" } ], "thumbnails_object": true } ``` ### Social media previews Different platforms expect different crop ratios for link previews, so generate them all from a single render rather than resizing client-side: ```json { "url": "https://stripe.com", "thumbnails": [ { "width": 1200, "height": 630, "key": "og" }, { "width": 1200, "height": 675, "key": "twitter" }, { "size": 400, "key": "square" } ], "thumbnails_object": true } ``` ### Gallery thumbnails Consistent, cropped square thumbnails for an image grid: ```json { "url": "https://stripe.com", "thumbnails": [ { "size": 150, "fit": "cover", "key": "grid" }, { "size": 300, "fit": "cover", "key": "preview" } ] } ``` --- # Configuring Azure Blob Storage > Save your screenshots, PDFs and other renders to an Azure Blob Storage container from Urlbox Source: https://urlbox.com/docs/storage/configure-azure-blob-storage Last updated: 2026-07-31 --- This guide walks through configuring Azure Blob Storage so that Urlbox stores screenshots and other renders directly in a blob container you control. **Azure is not S3-compatible.** Our other storage integrations (S3, Cloudflare R2, Backblaze B2, DigitalOcean Spaces, Google Cloud Storage) all speak the S3 API, so they share one set of credentials and options: an access key and secret, a bucket, and the [`use_s3`](https://urlbox.com/docs/options.md#use_s3) / [`s3_path`](https://urlbox.com/docs/options.md#s3_path) render options. Azure Blob Storage is its own protocol, so it takes different credentials (a storage account, a container, and a **SAS token** instead of a key/secret pair) and different render options ([`use_azure`](https://urlbox.com/docs/options.md#use_azure) / [`azure_path`](https://urlbox.com/docs/options.md#azure_path)). None of the `s3_*` options apply to an Azure configuration. ## Create a storage account and container Log in to the [Azure Portal](https://portal.azure.com) and create a storage account if you don't already have one: search for **Storage accounts**, click **Create**, pick a subscription, resource group, and a globally unique account name. The defaults (Standard performance, locally-redundant storage) are fine for storing renders. Once the account is deployed, open it and go to **Data storage → Containers**, then click **+ Container**. Give it a name like `renders` and leave the access level at **Private** for now (see [serving renders publicly](#serving-renders-publicly) below). ## Generate a SAS token Urlbox authenticates with a [shared access signature (SAS)](https://learn.microsoft.com/en-us/azure/storage/common/storage-sas-overview) rather than your account keys, so you never hand us full control of the storage account and you can scope and expire our access. Generate a **container-level** token: open your container, then go to **Settings → Shared access tokens**. - **Permissions:** `Write`, `Add` and `Create` are what Urlbox needs to upload renders. `Read` is optional (it lets the connection test read back what it wrote), and `Delete` is optional (if granted, the connection test cleans up its test blob; without it the test blob is left behind for you to delete). - **Expiry:** choose deliberately. When the token expires, renders using `use_azure` start failing until you paste a new token into the dashboard. A long expiry is convenient; a shorter one with rotation is safer. Click **Generate SAS token and URL** and copy the **Blob SAS token** value (the query string beginning `sv=...`), not the full URL. A leading `?` is fine either way - Urlbox strips it. ## Add the credentials to Urlbox In the [Urlbox dashboard](https://urlbox.com/dashboard/projects.md), open your project's settings and scroll to the **Azure Blob Storage Configuration** section: ![Azure Blob Storage Configuration section](/docs/azure/azure-configure-button.png) Click **Configure Azure Blob Storage** and fill in the three fields: the storage account name, the container name, and the SAS token you just generated: ![Azure config form filled in](/docs/azure/azure-form-filled.png) Click **Test connection** to verify the credentials before saving. Urlbox uploads a small test blob to your container (under `delete_me/`) to prove it has write access, and deletes it again if the token has `Delete` permission: ![Successful Azure connection test](/docs/azure/azure-test-connection.png) Then click **Save Azure Config**: ![Azure configuration saved](/docs/azure/azure-configured.png) A project uses either an S3-compatible configuration or an Azure configuration, not both at once - the storage slot on a project holds one credential. ## Saving renders to your container Set [`use_azure=true`](https://urlbox.com/docs/options.md#use_azure) on a render to store the result in your container: ```json { "url": "https://example.com", "use_azure": true } ``` By default renders are stored under `renders/{year}/{month}/{day}/{renderId}` with the file extension appended automatically. Use [`azure_path`](https://urlbox.com/docs/options.md#azure_path) to control the path and filename, exactly like `s3_path` does for S3: ```json { "url": "https://example.com", "use_azure": true, "azure_path": "screenshots/homepage/2026-07-31" } ``` The extension (e.g. `.png`, `.pdf`) is added automatically, and [`no_suffix=true`](https://urlbox.com/docs/options.md#no_suffix) disables that. `use_azure` and `use_s3` are mutually exclusive - a request setting both fails. The render response and webhook then point at your blob, e.g. `https://youraccount.blob.core.windows.net/renders/screenshots/homepage/2026-07-31.png`. ## Serving renders publicly A private container (the default) means Urlbox can write renders but the blob URLs won't be publicly readable - fine if your systems fetch them with their own Azure credentials. If you want the returned URLs to be directly usable: - **Anonymous blob access:** set the container's access level to **Blob** (anonymous read access for blobs only). Blob URLs then work for anyone who has them. - **CDN or custom domain:** front the container with Azure CDN or Front Door on your own domain, and set the [`cdn_host`](https://urlbox.com/docs/options.md#cdn_host) option (or the CDN Host field in your project's storage settings) to that hostname. Urlbox then returns URLs on your domain instead of `*.blob.core.windows.net`. ## Differences from the S3-compatible providers | | S3-compatible (S3, R2, B2, Spaces, GCS) | Azure Blob Storage | | ----------------- | --------------------------------------- | ----------------------------------------------------- | | Credentials | Access key + secret | Account name + container + SAS token | | Location fields | Bucket, region, endpoint | Container only (the account name determines the URL) | | Enable per render | `use_s3=true` | `use_azure=true` | | Path option | `s3_path` | `azure_path` | | Expiry | Keys live until revoked | SAS tokens expire on the date you set - plan rotation | If the provider you use speaks the S3 API (most do), follow the [S3 guide](https://urlbox.com/docs/guides/s3.md) instead; this page is only for Azure. --- # Configuring Backblaze B2 > Save your screenshots, PDFs and other renders to a Backblaze B2 bucket from Urlbox Source: https://urlbox.com/docs/storage/configure-backblaze-b2 Last updated: 2026-07-31 --- This guide will walkthough the process of configuring Backblaze B2 so that you can store screenshots and other renders directly to your Backblaze B2 public or private bucket. ## Create Backblaze B2 Public Bucket Log in to your Backblaze account and head to the B2 Cloud Storage section from the sidebar. Click into `Buckets` and then hit the `Create a Bucket` button and fill out the form. For this guide we'll call the bucket `urlbox-renders` and make the files in it public. Now click the `Create Bucket` button to create the bucket. ![create b2 bucket](/docs/b2/create-b2-bucket.png) ## Create an Application Key to allow write access to the bucket Once the bucket has been created, we need to create an application key which Urlbox can use in order to upload your renders to the bucket. In the Account section, click into Application Keys and then click the `Add a New Application Key` button. Give your key a name, something like `urlbox` should do. You can choose to allow access to all buckets or select a specific bucket. For this guide we'll lock-down access to just the `urlbox-renders` bucket that we just created. You can choose `Write Only` for the type of access to grant, as Urlbox only needs to be able to upload files to the bucket. The fact that the bucket is public means Urlbox will be able to serve the renders direct from the bucket. Then click the `Create New Key` button to create the key. ![create b2 key](/docs/b2/create-b2-key.png) Once the application key is created, the backblaze will display your credentials temporarily. The `keyId` is the access key and the `applicationKey` will be the secret key that we feed to Urlbox in the next step, so make sure to copy them somewhere safe. ## Add Backblaze B2 credentials to Urlbox Now we can go back to the Urlbox dashboard. From within the project settings page, scroll down to the S3 Configuration section and click the `Add S3 Config` button. Use the following settings: - **Access Key** The `keyId` value from the application key - **Secret** The `applicationKey` value from the application key - **Bucket Name** The name of the bucket you created earlier - **Private Bucket** Because this bucket is public, leave this option unchecked - **Endpoint URL** For the endpoint URL we can go to our bucket page and see what endpoint we have been assigned: ![b2 bucket endpoint](/docs/b2/b2-bucket-endpoint.png) It should look something like `s3.us-west-001.backblazeb2.com` but might be different for your bucket. Make sure to add `https://` to the start of the endpoint URL when adding it to Urlbox. - **Region** Set to the middle part of the endpoint URL, so for the example above it would be `us-west-001`. The final s3 config should look like this once it has been filled out correctly: ![add to s3](/docs/b2/add-to-s3.png) Then click `Save S3 Config`, and if everything is configured correctly, the form should disappear and you should see a success message. When you click `Save S3 Config` on the form, Urlbox will attempt to upload a file to your bucket at `urlbox_test/deleteme.txt` to ensure that the credentials given allow write access to the bucket. ## Using a private B2 Backblaze bucket In order to use a private B2 bucket, change your bucket settings in B2 to make the files in the bucket private. Then in your Urlbox S3 settings, check the Private Bucket option, which was previously left unchecked. Now when you save a render to your bucket with Urlbox, the file will be private and will not be accessible to the public. If using render links with a private bucket, Urlbox will now return a JSON response with a link to your private render, rather than attempt to serve the image. ## Start saving screenshots to your B2 bucket Now that your Backblaze B2 bucket is configured correctly, you can start saving screenshots to it. You can do this by setting the [`use_s3`](https://urlbox.com/docs/options.md#use_s3) option to true in your API request. You can use [`s3_path`](https://urlbox.com/docs/options.md#s3_path) to specify the path in your bucket to save the screenshot to. For more options related to how renders are saved to your B2 bucket, please see the [saving to s3 compatible storage](https://urlbox.com/docs/guides/s3.md) guide. --- # Configuring Cloudflare R2 > Save your screenshots, PDFs and other renders to a Cloudflare R2 bucket from Urlbox Source: https://urlbox.com/docs/storage/configure-cloudflare-r2 Last updated: 2026-07-31 --- This guide will walkthough the process of configuring Cloudflare R2 so that you can store screenshots and other renders directly to your Cloudflare R2 bucket. ## Create R2 Bucket Log in to your Cloudflare account and head to the R2 section from the sidebar. Click the `Create Bucket` button and fill out the form. For this guide we'll call the bucket `urlbox-renders` and optionally give a location hint of Eastern North America. The location should be closest to where you expect most of your users to be located. Now click the `Create Bucket` button to create the bucket. ![create bucket](/docs/r2/create-bucket.png) ## Get the S3 Endpoint for your R2 bucket Once the bucket has been created, click on the settings tab to access the bucket settings. You should see a section called `Bucket Details` which contains an S3 API URL. This URL, minus the bucket name, will become the S3 endpoint that we will use later when adding the config to your Urlbox project. It should be of the form: `https://<ACCOUNT_ID>.r2.cloudflarestorage.com/<bucket_name>`, where ACCOUNT\_ID is your Cloudflare account id. The endpoint URL we will use is actually just `https://<ACCOUNT_ID>.r2.cloudflarestorage.com`. ![bucket settings](/docs/r2/bucket-settings.png) ## Create an R2 Token In your Cloudflare account, go back to the R2 home screen again and click the `Manage R2 API Tokens` in the right hand sidebar. Then click the `Create API token` button. Give the token a name, something like `Urlbox` should do. In the permissions, you'll need to give `Object Read & Write` access, so that Urlbox can write, i.e. upload the renders to your R2 bucket. Under specify buckets, you can choose whether this token has access to all buckets, or just a specific bucket. Under TTL, you can specify how long the token should be valid for until it expires. For simplicity we'll set it to `Forever`, but you may want to use a shorter expiry and figure out a way to rotate the R2 token when it expires. Now that you've filled out all the settings, click the `Create API Token` button to create the token. ![create token](/docs/r2/create-r2-token.png) On the following page, you'll see the token that you just created. At the bottom of the page, it will show you the access key and secret key credentials for S3 clients, which is what we're after. Copy and paste them to a safe place, as you won't be able to see them again. ## Adding the R2 credentials to Urlbox Now we can go back to the Urlbox dashboard. From within the project settings page, scroll down to the S3 Configuration section and click the `Add S3 Config` button. We can copy the access key and secret key from our R2 token into the S3 config form. We should also add the bucket name as `urlbox-renders` (or whatever you named your bucket) and we set the region to `auto`. `us-east-1` should also work, according to the [cloudflare R2 docs](https://developers.cloudflare.com/r2/api/s3/api/#bucket-region). By default, the cloudflare bucket is created with restricted access, so we need to check the `Private Bucket` option. This will mean that Urlbox will only be able to store the renders in the bucket, but is not able to serve them. See the next section if you want Urlbox to be able to serve the files from your bucket. ![add s3 keys](/docs/r2/add-s3-keys-private.png) We also need to set the S3 endpoint to the one that we copied from the R2 bucket settings page, it should look something like: `https://<ACCOUNT_ID>.r2.cloudflarestorage.com`, note that it does not include the bucket name. Then click `Save S3 Config`, and if everything is configured correctly, the form should disappear and you should see a success message. When you click `Save S3 Config` on the form, Urlbox will attempt to upload a file to your bucket at `urlbox_test/deleteme.txt` to ensure that the credentials are correct. Because Urlbox does not have delete credentials on your bucket, this file will remain in your bucket and you can delete it once the bucket is configured correctly. ## Using a public R2 bucket If you prefer Urlbox to serve the renders from your R2 bucket, you can make your bucket public and expose its contents directly to the Internet. See [public R2 buckets](https://developers.cloudflare.com/r2/buckets/public-buckets/) documentation on Cloudflare for more info on how to configure this. The best way to configure a public R2 bucket is to connect your bucket to a custom domain. For example, if your main domain is `mydomain.com`, you could connect your bucket to a subdomain such as `renders.mydomain.com`. ![custom domain](/docs/r2/add-custom-domain.png) Then you can set `CDN Host` option in the Urlbox S3 config to your custom domain, e.g. `renders.mydomain.com`, and ensure that the `Private Bucket` option is now unchecked. ![add s3 keys](/docs/r2/add-s3-keys-public.png) Once you've done this, Urlbox will use the custom domain to serve the renders from your bucket. ## Start saving screenshots to your R2 bucket Now that your R2 bucket is configured correctly, you can start saving screenshots to it. You can do this by setting the [`use_s3`](https://urlbox.com/docs/options.md#use_s3) option to true in your API request. For more options on how to configure how renders are saved to your R2 bucket, please see the [saving to s3 compatible storage](https://urlbox.com/docs/guides/s3.md) guide. --- # Configuring Digital Ocean Spaces > Save your screenshots, PDFs and other renders to a Digital Ocean Spaces bucket from Urlbox Source: https://urlbox.com/docs/storage/configure-digitalocean-spaces Last updated: 2026-07-31 --- This guide will walkthough the process of configuring Digital Ocean Spaces so that you can store screenshots and other renders directly to your Digital Ocean Spaces public or private bucket. ## Create Digital Ocean Spaces Public Bucket Log in to your Digital Ocean account and head to the Spaces Object Storage section from the sidebar. Click `Create a Spaces Bucket` and fill out the form. For this guide we'll call the bucket `urlbox-renders` and choose `nyc3` for the region. You can optionally choose to enable the CDN option if you're wanting to serve the renders using a custom domain. ![create do-spaces bucket](/docs/do-spaces/create-bucket.png) Now click the `Create a Spaces Bucket` button to create the bucket and you should see your empty bucket: ![do-spaces bucket created](/docs/do-spaces/bucket-created.png) ## Create a Spaces Key in order to upload renders Once the spaces bucket has been created, we need to create a spaces key which Urlbox can use in order to upload your renders to the bucket. In the API section in the sidebar, click the `Spaces Keys` tab and then `Generate New Key`. ![create spaces key](/docs/do-spaces/create-spaces-key.png) Give your key a name, something like `urlbox` should do, and click `Create Access Key`. Once the spaces key is created, Digital Ocean will display your access key and secret key. Make sure to copy the secret key down somewhere safe as it won't be shown again: ![spaces key created](/docs/do-spaces/spaces-key-created.png) ## Add your Digital Ocean Spaces Key credentials to Urlbox Now we can go back to the Urlbox dashboard. From within the project settings page, scroll down to the S3 Configuration section and click the `Add S3 Config` button. Use the following settings: - **Access Key** The access key from the spaces key you created - **Secret** The secret key from the spaces key you created - **Bucket Name** The name of the spaces bucket you created earlier - **Private Bucket** Because this bucket is public, leave this option unchecked - **Endpoint URL** For the endpoint URL we can go to our bucket page and see the endpoint we have been assigned: ![spaces bucket endpoint](/docs/do-spaces/bucket-endpoint.png) It should look something like `https://<your-bucket-name>.nyc3.digitaloceanspaces.com` however, we need to remove the bucket name to make it compatible with Urlbox. Remove the bucket name from the first part of the domain, so it should look like `https://nyc3.digitaloceanspaces.com`. - **Region** Set the region to `us-east-1` regardless of your Digital Ocean spaces region. The final s3 config should look like this once it has been filled out correctly: ![urlbox config do](/docs/do-spaces/urlbox-config-do.png) Then click `Save S3 Config`, and if everything is configured correctly, the form should disappear and you should see a success message. When you click `Save S3 Config` on the form, Urlbox will attempt to upload a file to your bucket at `urlbox_test/deleteme.txt` to ensure that the credentials given allow write access to the bucket. ### Troubleshooting If you see an error about `Hostname/IP does not match certificate's altnames` it means you have entered the endpoint URL incorrectly. Please ensure you have removed the bucket name from the endpoint URL that is displayed on your spaces bucket page, before sending the configuration details to Urlbox. ## Save a test render to your Digital Ocean Spaces bucket Now that your Digital Ocean Spaces bucket is configured, you can run a test render to ensure that everything is working correctly. Go to the sandbox and enter a URL to render, scroll down to the Upload settings and check the `Use S3` option. You can also set an S3 Path to save the render to, for example `myscreenshots/test.png`: ![test render](/docs/do-spaces/test-render.png) Then click `Render` and if everything is configured correctly, you should see the rendered screenshot and the render should be saved to your Digital Ocean Spaces bucket at the specified path: ![test render in bucket](/docs/do-spaces/test-render-in-bucket.png) If you click the `Open in new tab` link under the screenshot, you'll see that the URL is now a Digital Ocean Spaces URL. ## Keeping your renders private If you'd prefer not to have your renders publicly accessible, you can keep them private. By default, files in Digital Ocean Spaces buckets are kept private, you just need to tell Urlbox that you want to keep them private. In your Urlbox S3 settings, check the Private Bucket option, which was previously left unchecked. Now when you save a render to your bucket with Urlbox, the file will be private and will not be accessible to the public. If using render links with a private bucket, Urlbox will now return a JSON response with a link to your private render, rather than attempt to serve the image. When you try another test render, the sandbox will show a success message but not show the screenshot as it is now private: ![sandbox private render](/docs/do-spaces/sandbox-private-render.png) ## Using a CDN If you configured a CDN with your Digital Ocean Spaces bucket, make sure to specify the CDN Host in the `CDN Host` field in your Urlbox S3 settings, then Urlbox will substitute the hostname for the CDN Host you specified in your render URL. ## Start saving screenshots to your Digital Ocean Spaces bucket Now that your Digital Ocean Spaces bucket is configured correctly, you can start saving screenshots to it. You can do this by setting the [`use_s3`](https://urlbox.com/docs/options.md#use_s3) option to true in your API request. You can use [`s3_path`](https://urlbox.com/docs/options.md#s3_path) to specify the path in your bucket to save the screenshot to. For more options related to how renders are saved to your Digital Ocean Spaces bucket, please see the [saving to s3 compatible storage](https://urlbox.com/docs/guides/s3.md) guide. --- # Configuring Google Cloud Storage > Save your screenshots, PDFs and other renders to Google Cloud Storage from Urlbox Source: https://urlbox.com/docs/storage/configure-google-cloud-storage Last updated: 2026-07-31 --- This guide will walkthough the process of configuring Google Cloud Storage (GCS) so that you can store screenshots and other renders directly to your bucket in Google Cloud, using either a private or public bucket. ## Create a private Google Cloud Storage Bucket Log in to your Google Cloud account and head to the Cloud Storage section from the sidebar. On the buckets sub page, click the `Create` button and fill out the form. For this guide we'll call the bucket `urlbox-renders-private`. Then you can choose where you want to store your bucket, choose a location that is closest to your users, then choose a storage class for your data. The next section is `Choose how to control access to objects`. Since we want this bucket to be private, you should tick the box that says `Enforce public access prevention on this bucket`. If you do want to configure a public bucket instead see the section further down. Under the Access control subheading, you can decide whether to use Uniform or Fine-grained access to control access to your objects. For this guide, we'll use Uniform access. ![access control private](/docs/gcs/access-control-private.png) Finally, you can choose whether you want to protect your data, using a retention policy or versioning. For this guide, we'll select no protection. Below are the bucket settings I configured for this guide: ![bucket settings](/docs/gcs/bucket-settings.png) Now click the `Create` button to create the bucket. If you get a popup titled `Public access will be prevented`, just ensure the `Enforce public access prevention on this bucket` setting is checked and click confirm. ![public access warning](/docs/gcs/public-access-warning.png) ## Create a service account Now it's time to create a service account that Urlbox can use to upload screenshots and other renders to your bucket. If you already have a service account that you'd like to use, you can skip this section. Go to the IAM and admin > Service accounts page in Google Cloud, and click the `Create Service Account` button. We'll name the service account `urlbox-storage` and give it a relevant description. You can skip the next sections and click `Done` to create the service account. ![service account](/docs/gcs/service-account.png) Copy the email address of the service account as we will need that in the next step. ## Grant the service account access to your bucket Go back to the bucket you created, and click the `Permission` tab. Then click `Grant Access`. In the popup form, paste the service account's email address into the `New principals`. Under `Assign Roles`, make sure to assign the `Storage Object Admin` role which you'll find inside the Cloud Storage service to the service account. \~> Why `Storage Object Admin` and not just `Storage Object Creator`? Because Urlbox sometimes needs to be able to overwrite existing files in your bucket, and the `Storage Object Creator` role does not allow this. You *can* select `Storage Object Creator` if you prefer, but you will get an error when saving a render if the file already exists in your bucket. ![grant access](/docs/gcs/grant-access.png) Then click `Save`. ## Create credentials for your service account The next step is to generate HMAC credentials for your service account. To do this, go to the Cloud Storage > Settings page. Then select the `Interoperability` tab and click `Create a key for a service account`. ![create service account key](/docs/gcs/create-service-account-key.png) In the popup form, select the service account you created earlier, and click `Create Key`. ![select service account](/docs/gcs/select-service-account.png) Now you should note down both the Access key and secret so we can add them to the Urlbox config. ## Add the service account credentials to Urlbox Now we can go back to the Urlbox dashboard. From within the project settings page, scroll down to the S3 Configuration section and click the `Add S3 Config` button. Use the following settings: - Access Key: The access key from the service account credentials - Secret: The secret key from the service account credentials - Bucket Name: The name of the bucket you created earlier - Private Bucket: Checked - Region: Set this to `auto`. - Endpoint URL: `https://storage.googleapis.com`. ![add gcs keys to urlbox](/docs/gcs/add-gcs-keys.png) Then click `Save S3 Config`, and if everything is configured correctly, the form should disappear and you should see a success message. When you click `Save S3 Config` on the form, we will attempt to upload a file to your bucket at `urlbox_test/deleteme.txt` to ensure that the credentials are correct. If there is an error uploading the test file to your bucket, we will show the error as it appears from Google Cloud. Please ensure you have followed all the steps above correctly to ensure the settings are correct. Check the permissions tab of your bucket settings to ensure that the correct service account has access, and has the `Storage Object Admin` role. ## Start saving screenshots to your S3 bucket Now that your GCS bucket is configured correctly, you can start saving screenshots to it. You can do this by setting the [`use_s3`](https://urlbox.com/docs/options.md#use_s3) option to true in your API request. Please note that because the bucket doesn't have public access, urlbox cannot serve the renders directly from your bucket, in order to configure public access, see the next section. To see the options that configure how renders are saved to your GCS bucket, please see the [saving to s3 compatible storage](https://urlbox.com/docs/guides/s3.md) guide. ## Using a public GCS bucket If you prefer Urlbox to serve the renders from your GCS bucket, you can make your bucket public and expose its contents directly to the Internet. There are two steps to enable public access on your bucket: 1. Go back to the bucket settings page in Google Cloud. Then click the `Permissions` tab and disable public access prevention by clicking on the `Remove Public Access Prevention` button. Click `Confirm` on the warning popup. 2. Also in the permissions tab, click `Grant Access` and then add the principle `allUsers` and assign the `Storage Object Viewer` role to it. Click `Save` and then `Allow Public Access` in the warning popup. ![make bucket public](/docs/gcs/make-bucket-public.png) ![confirm public access](/docs/gcs/confirm-public-access.png) Over in the Urlbox S3 settings panel, uncheck the `Private Bucket` setting, and re-save. If everything is working, the form should disappear and you should see a success message. Now when you request a screenshot with `use_s3` set to true, the screenshot will be saved to your bucket and can also be served from there. --- # Configuring a private S3 bucket > Save your screenshots, PDFs and other renders to a private S3 bucket from Urlbox Source: https://urlbox.com/docs/storage/configure-s3-private Last updated: 2026-07-31 --- This guide will walkthough the process of configuring a **private** S3 bucket which means Urlbox can only store your renders but cannot access them. The process of configuring a private S3 bucket and credentials can be quite complicated, so we've put together this guide to help you through the process. It consists of the following steps: - Creating a new private S3 bucket with the correct settings - Creating a new IAM user - Create a new IAM user group - Adding the IAM user to the group - Creating a policy on the group to allow upload access to the bucket - Generating an access key and secret key for the IAM user - Adding the credentials to your project in Urlbox ## Configuring S3 Over in your AWS account, you should create an S3 bucket and an IAM user that has the minimal settings allowed for Urlbox to save to your bucket only. In private bucket mode, Urlbox will not be able to serve the renders from your bucket. ### Creating an S3 Bucket From the AWS console, navigate to the S3 service and click the `Create Bucket` button. Fill in the required fields, such as the bucket name, and desired region where you want the bucket to be located. For this example, we'll use the bucket name `private-render-demo` and the region `eu-west-2`. ### Object Ownership, ACLs and Public Access Settings You can leave ACL's disabled as Urlbox will not be using them in private bucket mode. You can also leave the public access settings as the default - Block *all* public access. ![S3 Bucket Settings](/docs/s3/s3-private-settings.png) Next click the `Create bucket` button to create your S3 bucket. ## Creating an IAM User with access to the bucket From the AWS console, navigate to the IAM service and click the `Users` link in the left hand menu. Then click the `Create User` button. Name the user something like `urlbox-s3-private` and click next. ![create IAM User](/docs/s3/create-iam-user-private.png) On the next screen, select the `Add User to Group` option, and then click the `Create Group` button. Enter a name for the group you want to add the user to, something like `urlbox` should make sense and then create the user group. ![create User group](/docs/s3/create-user-group-private.png) Back on the create user wizard, click next and then create user. ## Adding a bucket policy to the user group The only permissions that Urlbox needs to save renders to your private bucket is the `s3:PutObject` permission. Now go back to the user group you created, and ensure that the IAM user you created is a part of the group. Next it's time to add a policy to the group, so that the user can access the bucket you created. Click the `Permissions` tab, and then click the `Add permissions` dropdown and then `Create inline policy`. In the policy editor that pops up, switch to JSON view and paste the following JSON policy in: ```json { "Version": "2012-10-17", "Statement": [ { "Sid": "Stmt1505247412000", "Effect": "Allow", "Action": ["s3:PutObject"], "Resource": ["arn:aws:s3:::private-render-demo/*"] } ] } ``` You'll need to replace the `private-render-demo` part of the `Resource` key with the name of your bucket. Alternatively, if you'd like this policy to apply to all buckets, you can set the Resource to `arn:aws:s3:::*/*`. These are the minimum permissions required for Urlbox to save renders to your bucket. They won't allow Urlbox to access the renders or serve them. Once you've pasted in the policy, click the `Review Policy` button, and then give the policy a name, something like `urlbox-s3-policy` should make sense. ## Generating an access key and secret key for the IAM user Now that the user has been created, and has the correct permissions, we need to generate an access key and secret key for the user. Open the user again in the IAM console, and click the `Security credentials` tab. Scroll down to the Access keys section. Then click the `Create access key` button. You will want to tell AWS that the purpose of this access key is for a third party service. It will recommend that you use IAM roles in order to provide short term credentials to a third party, however because we have locked down the access that this user has to the least privileges required by urlbox, it is safe to use the access key and secret key directly. If you do want to use IAM roles with Urlbox, you will need to figure out a way to refresh them each time they expire, and update the project settings with the fresh credentials. Now you have created the access keys, it's time to copy them to your clipboard and make sure you don't lose them, as you won't be able to see them again. ![access key created](/docs/s3/access-key-created-private.png) ## Adding the S3 config to your project Now we can go back to the Urlbox dashboard. From within the project settings page, scroll down to the S3 Configuration section and click the `Add S3 Config` button. We can copy the access key and secret key from our IAM user into the S3 config form. Also add the region as `eu-west-2` and the bucket name as `private-render-demo` (or whatever you named your bucket). Crucially, you need to enable the `Private Bucket` option, to tell Urlbox that it will not be able to serve the renders from your bucket. ![add s3 keys](/docs/s3/add-s3-keys-private.png) Then click `Save S3 Config`, and if everything is configured correctly, the form should disappear and you should see a success message. When you click `Save S3 Config` on the form, Urlbox will attempt to upload a file to your bucket at `urlbox_test/deleteme.txt` to ensure that the credentials are correct. Because Urlbox does not have delete credentials on your bucket, this file will remain in your bucket and you can delete it once the bucket is configured correctly. ## Debugging Errors If you see an error message when you click `Save S3 Config`, it means that Urlbox was unable to upload the test file to your bucket. This could be for a number of reasons: - The bucket name is incorrect - The bucket does not exist - Bucket does not have the correct public settings - Bucket does not have the correct ACL settings - The IAM user does not have the correct permissions Please check all of the above and follow the steps in this guide to ensure that the S3 bucket is configured correctly. Please reach out to support if you are still having issues. ## Start saving screenshots to your private S3 bucket Now that your private S3 bucket is configured correctly, you can start saving screenshots and other renders to it. When using the Urlbox API, a successful response will still return a `renderUrl` pointing to the file in your private bucket, however accessing this link will likely give an access denied error becuase the bucket is private. When using render links with a private bucket, because Urlbox has only been granted write permissions, it is not possible to serve the images directly, so Urlbox will return a JSON response instead of the usual binary response. You can do this by setting the [`use_s3`](https://urlbox.com/docs/options.md#use_s3) option to true in your API request. For more options on how to configure how renders are saved to your S3 bucket, please see the [saving to s3](https://urlbox.com/docs/guides/s3.md) guide. --- # Configuring S3 > Save your screenshots, PDFs and other renders to an S3 bucket from Urlbox Source: https://urlbox.com/docs/storage/configure-s3 Last updated: 2026-07-31 --- This guide will walkthough the process of configuring a *public* S3 bucket which means Urlbox can store your renders and also serve them when using render links. If you prefer to keep your S3 bucket private, and only use Urlbox to store renders, but not serve them, please follow our guide on [configuring a private S3 bucket with Urlbox](https://urlbox.com/docs/storage/configure-s3-private.md). The process of configuring an S3 bucket with the correct settings for Urlbox can be quite complicated, so we've put together this guide to help you through the process. It consists of the following steps: - Creating a new S3 bucket with the correct ACL and public access settings - Creating a new IAM user - Create a new IAM user group - Adding the IAM user to the group - Setting a policy on the group to allow access to the bucket - Generating an access key and secret key for the IAM user - Adding the credentials to your project in Urlbox ## Configuring S3 Over in your AWS account, you should create an S3 bucket and an IAM user that has the minimal settings allowed for Urlbox to save to your bucket, as well as being able to serve the renders from it. ### Creating an S3 Bucket From the AWS console, navigate to the S3 service and click the `Create Bucket` button. Fill in the required fields, such as the bucket name, and desired region where you want the bucket to be located. For this example, we'll use the bucket name `screenshots-demo` and the region `us-east-1`. ### Object Ownership Ensure that ACLs are **enabled** for the bucket, and object ownership can be set to the bucket owner. ### Block Public Access settings for this bucket You'll want to untick the `Block all public access` checkbox, and then tick the bottom two checkboxes labelled: - Block public access to buckets and objects granted through new public bucket or access point policies - Block public and cross-account access to buckets and objects through any public bucket or access point policies ![S3 Block Public Access](/docs/s3/s3-block-public-access.png) The reason we want to allow public access, is so that when Urlbox saves a render to your bucket, it can be served by Urlbox aswell. Once the ACL and access settings are configured, click the `Create bucket` button to create your S3 bucket. ## Creating an IAM User with access to the bucket From the AWS console, navigate to the IAM service and click the `Users` link in the left hand menu. Then click the `Create User` button. Name the user something like `urlbox-s3` and click next. ![create IAM User](/docs/s3/create-iam-user.png) On the next screen, select the `Add User to Group` option, and then click the `Create Group` button. Enter a name for the group you want to add the user to, something like `urlbox` should make sense and then create the user group. ![create User group](/docs/s3/create-user-group.png) Back on the create user wizard, click next and then create user. ## Adding a bucket policy to the user group The permissions that Urlbox needs in order to save renders to your bucket, and serve them from it, are: - `PutObject` - to upload the render to your bucket - `PutObjectAcl` - to add the ACL `public-read` to the uploaded object, so that anyone can view it. - `GetObject` - to allow Urlbox to get metadata about the object, such as the size, and also to serve the object when using render links. Now go back to the user group you created, and ensure that the IAM user you created is a part of the group. Next it's time to add a policy to the group, so that the user can access the bucket you created. Click the `Permissions` tab, and then click the `Add permissions` dropdown and then `Create inline policy`. In the policy editor that pops up, switch to JSON view and paste the following JSON policy in: ```json { "Version": "2012-10-17", "Statement": [ { "Sid": "Stmt1505247412000", "Effect": "Allow", "Action": ["s3:GetObject", "s3:PutObject", "s3:PutObjectAcl"], "Resource": ["arn:aws:s3:::screenshots-demo/*"] } ] } ``` You'll need to replace the `screenshots-demo` part of the `Resource` key with the name of your bucket. These are the minimum permissions required for Urlbox to save renders to your bucket, and to serve them from it. Once you've pasted in the policy, click the `Review Policy` button, and then give the policy a name, something like `urlbox-s3-policy` should make sense. ## Generating an access key and secret key for the IAM user Now that the user has been created, and has the correct permissions, we need to generate an access key and secret key for the user. Open the user again in the IAM console, and click the `Security credentials` tab. Scroll down to the Access keys section. Then click the `Create access key` button.

From within the project settings page, scroll down to the S3 Configuration section and click the `Add S3 Config` button. We can copy the access key and secret key from our IAM users credentials into the S3 config form. We should also add the region as `us-east-1` and the bucket name as `screenshots-demo` (or whatever you named your bucket). Make sure not to select the private bucket option, as we are configuring a public bucket. ![add s3 keys](/docs/s3/add-s3-keys.png) Then click `Save S3 Config`, and if everything is configured correctly, the form should disappear and you should see a success message. When you click `Save S3 Config` on the form, Urlbox will attempt to upload a file to your bucket at `urlbox_test/deleteme.txt` to ensure that the credentials are correct.

By default the recording holds the page still for a few seconds. ```json { "url": "https://urlbox.com", "format": "mp4", "video_time": 6000 } ``` `video_time` sets the recording length in milliseconds (`video_duration` is the same thing in seconds). Frame rate, output size and encoding are controlled by [`video_fps`, `video_width`/`video_height`, `video_quality`, `video_preset` and `video_codec`](https://urlbox.com/docs/options.md#video-options). ## Scrolling videos Set `video_scroll` to true to smoothly scroll down the page while recording, great for showing off a long landing page the way a visitor would actually experience it. ```json { "url": "https://urlbox.com", "format": "mp4", "video_scroll": true, "video_time": 12000 } ``` The scroll's feel is fully tunable: how long each movement takes ([`video_scroll_duration`](https://urlbox.com/docs/options.md#video_scroll_duration)), pauses between movements ([`video_rest_duration`](https://urlbox.com/docs/options.md#video_rest_duration)), lead-in and tail time ([`video_prescroll_duration`](https://urlbox.com/docs/options.md#video_prescroll_duration), [`video_postscroll_duration`](https://urlbox.com/docs/options.md#video_postscroll_duration)), the easing curve ([`video_ease`](https://urlbox.com/docs/options.md#video_ease)), whether it scrolls back to the top ([`video_scroll_back`](https://urlbox.com/docs/options.md#video_scroll_back)), and human-like randomisation ([`video_jitter`](https://urlbox.com/docs/options.md#video_jitter)). If the page lazy-loads content, [`video_warmup`](https://urlbox.com/docs/options.md#video_warmup) does an unrecorded scroll first so everything is loaded before the take. ## Section-controlled scrolling Sometimes you don't want a constant scroll at all. You want to visit specific sections of the page and hold on each one for a set time, whether that's to highlight features in turn, build a guided walkthrough, or line the scroll up with a voiceover. That's what [`video_scroll_to`](https://urlbox.com/docs/options.md#video_scroll_to) does. ```json { "url": "https://urlbox.com", "format": "mp4", "video_scroll_to": [ "#full-page-screenshots;wait=3s", "text=Screenshots at internet scale;wait=3s" ] } ``` Each entry is a stop. The target can be: - **A CSS selector**: `#reviews`, `.pricing-table`, `[data-section=faq]`. Selectors automatically pierce open shadow DOM, so pages built from web components work without special syntax. - **A text locator**: `text=Customer Reviews` matches visible text (case-insensitive substring match, resolving to the deepest matching element), handy when a page has no useful ids. Each stop takes optional settings after `;` in a render link, or as object keys in a JSON body: | Key | What it does | Default | | ---------- | ------------------------------------------------------------------------------------------ | ---------------------------------- | | `wait` | How long to pause at the section (`4s`, `500ms`, or ms as a number) | `video_rest_duration`, else 2s | | `duration` | How long the scroll *to* this section takes | `video_scroll_duration`, else 1.5s | | `ease` | Easing for that scroll (see [`video_ease`](https://urlbox.com/docs/options.md#video_ease)) | `video_ease` | | `offset` | Stop N pixels above the element, which keeps sections visible under sticky headers | `video_scroll_offset`, else 0 | Set [`video_scroll_offset`](https://urlbox.com/docs/options.md#video_scroll_offset) to change that default for every section at once, rather than repeating `;offset=` on each stop. In a JSON body the same stops can be objects, which is easier to generate programmatically: ```json { "url": "https://urlbox.com", "format": "mp4", "video_scroll_to": [ { "selector": "#full-page-screenshots", "wait": "20s" }, { "text": "Screenshots at internet scale", "wait": 30000, "offset": 80 } ] } ``` ### Timeline behaviour The video's total length is derived from your stops. The scroll choreography (each scroll and wait) is capped at 400 seconds, with prescroll, scroll-back and postscroll time added on top. If you pass `video_time` explicitly, it caps the scroll choreography and truncates it. Lead-in, scroll-back and tail still ride on top. If a section isn't found on the page, Urlbox **holds the current position for that stop's full time slot** rather than skipping ahead. That keeps every later section on schedule, so the rest of your timeline stays in sync even if one selector breaks. If you'd rather fail loudly, set [`video_scroll_require_sections`](https://urlbox.com/docs/options.md#video_scroll_require_sections) to true and a missing section returns a 400 error naming the selector. ### Tips - Sections are visited in the order you pass them, and top-to-bottom order usually looks most natural. - Give the first stop a `wait` even if it's the top of the page; a beat on the hero reads better than an instant scroll. - Long choreographies can take minutes to render, so use the [async API with a webhook](https://urlbox.com/docs/webhooks.md) rather than a synchronous request. - Renders are cached like any other Urlbox render, so re-using the same render link serves the finished video instantly. --- # 10 years of Urlbox: 10 ways to improve your screenshots (7 new for 2022) > I rarely write about our business but this milestone felt worthy of an update. Source: https://urlbox.com/10-years Last updated: 2022-11-01 --- Customers like you have trusted us to take their website screenshots and convert HTML to images for over a decade. I rarely write about our business but this milestone felt worthy of an update... ## 10th Birthday Last Monday, 24th October 2022, was Urlbox Ltd's 10th birthday, I took the day off to spend time with family. It's been a busy year for the company. Me (Chris) became "we" with 8 other people working on Urlbox. That's not including over a dozen awesome writers who have also helped us out. ## Marketing We likely have you to thank for spreading the word for us up to now. Thank you! We've been profitable for years with very little marketing and no outside funding.

Most of our product development time has been invested in the things you've told us are most important: - Screenshot accuracy - Reliability & security - Rendering speed I'll write about each of these at some point (especially if you tell me you are interested). Explaining why we use kubernetes mixed with serverless functions feels a bit dry for this post. ## 10 Features Fortunately, with a larger team, we've also had time for some exciting feature improvements. So, here are 10 features we've worked on this year... including 7 new for 2022. 1. Metadata Extraction 2. Zapier Integration 3. S3 Integration 4. Custom Metadata 5. Webhooks 6. Post your HTML, CSS & JS 7. Animated Screenshots 8. Better Than Ever PDFs 9. GPU Acceleration 10. Scrolling Screenshots (Yes that's video just like you've seen in the [stunning Tailwind CSS Showcase](https://tailwindcss.com/showcase)) I'll share the detail of each of these over the next few weeks. Oh... and we've got even bigger plans for next year which we might give you a sneak peek of.

It took around 6 months to make contact with the owner, agree a price and complete the transfer. Steven from [Lumis](https://lumis.com) expertly handled the whole process for us. Today we completed the migration of our website and email. The API will continue to work via either domain so there's no need to take any action. It feels good. To be honest, we feel even better about the huge update to the [screenshot api docs](https://urlbox.com/docs) that we shipped at the end of 2023. --- # Urlbox is SOC2 Type II Attested > Urlbox's screenshot API is now SOC2 Type II attested. Source: https://urlbox.com/soc2-type-2-attested Last updated: 2026-02-12 --- Urlbox is now SOC2 Type II attested 🎉. Achieving SOC2 Type II means that we have put in place formal policies and controls to enforce our security standards, and their effectiveness has been independently audited over time. You can have confidence that Urlbox meets established enterprise security expectations. We are not just claiming that we are the secure way to take programmatic screenshots, we've proved it. If you are using our screenshot API, you may be capturing sensitive data: customer dashboards, pre-release products, internal tools, or confidential documents, all turned into images, PDFs, Markdown files, or other render types we offer. These websites' renders and even their URLs can contain sensitive information you cannot afford to leak. ## What It Means SOC2 is a framework developed by the American Institute of Chartered Public Accountants. It evaluates how a companies' [information security](https://en.wikipedia.org/wiki/Information_security) policies and practices protect their customer data, across five 'trust principles': security, availability, processing integrity, confidentiality, and privacy. Type II attestation holds you under more scrutiny than Type I. While Type I looks at whether the controls you have in place are designed and implemented correctly at a single point in time, Type II examines whether those controls actually operate effectively over an extended period. Our first SOC2 Type II audit covered the Security principle over a three-month audit window. The independent auditor, [Prescient Security](https://prescientsecurity.com), verified that our controls are designed and functioning effectively, with no exceptions. They held us to account for three months, and we will be monitored going forward to maintain continuous SOC2 compliance. We also used [Vanta](https://vanta.com) to manage our compliance programme, helping us continuously monitor controls and maintain evidence in a structured, auditable way. It saved us a lot of time otherwise manually collating evidence. From the outside, SOC2 can look like a checkbox exercise. In reality, it required us to take a step back and review our policies and controls, then ensure we consistently operated in compliance with them. Much of what we documented reflected practices we already had in place, but the process forced us to examine them closely and deliberately, validating and ultimately strengthening them. The investment we've made in pursuing this has made security more intentional and more visible in our day-to-day work. We now have a clearer understanding of what enterprise teams expect from us, and a transparent way to demonstrate that through our trust page. SOC2 Type II gives us a structured, externally validated way to show that security, transparency, and reliability are values we hold in high priority. ## Enterprise-Ready Screenshots Our secure screenshot API processes millions of renders per year for a wide range of customers, from indie devs to enterprises. We are already GDPR-compliant, and now we are proudly SOC2 attested. We offer security-first features like `secure_mode`, the ability to upload finished renders directly to your own storage (including private S3 buckets and Azure Blob Storage), and AI analysis with a bring-your-own AI approach, so your data is never trained or processed outside of your control. You can view our security posture at [trust.urlbox.com](https://trust.urlbox.com/), and can access our SOC2 report for your compliance review there. If you have any questions about our security practices or anything else, hit the chat widget on our website or email us at [support@urlbox.com](mailto:support@urlbox.com). --- # Urlbox CLI: screenshots from your terminal — or your agent > Take screenshots from the command line with the Urlbox CLI — or hand it to an AI agent and have a screenshot saved in under a minute. Install from npm. Source: https://urlbox.com/urlbox-cli Last updated: 2026-07-13 --- The Urlbox CLI lets you call the Urlbox screenshot API straight from your terminal. And even better: you can hand it to an AI agent and have it taking screenshots in under a minute. That's the pitch. The rest of this post backs it up — stopwatch included. None of this is newly *possible* — you could always do it through the [Urlbox API](https://urlbox.com/docs.md). But now you can simply tell an agent: "Use the Urlbox CLI to screenshot these URLs..." and it can install it, understand it, and take your first screenshot in just under a minute. Here's the plain version, a screenshot straight from your shell: ```sh urlbox screenshot https://stripe.com --full-page --output stripe.png ``` (That `--full-page` flag captures the whole scrolling page, not just the viewport.) Or you may want a PDF or even a video? ```sh urlbox pdf https://stripe.com/pricing --output pricing.pdf urlbox video https://theverge.com --output verge.mp4 ``` That's the terminal version. Now the agent version. ## Urlbox is now agent-accessible Three pieces, working together: - **The API** — the rendering engine, same as always. - **The CLI** — puts it in your terminal. - **The agent skill** — one command teaches your agent how to use it. The upshot is simple: **anything you can do with the Urlbox API, you can now get an agent to do in plain English.** ## The experiment we ran We walked the exact cold path an agent takes — install, discover, render — and put a stopwatch on every step. **Cold machine to a saved screenshot: about a minute.** Here's where the time goes: - **Install from npm:** \~30 seconds. - **The tool explains itself:** `urlbox commands` returns every command and flag as structured JSON. An agent reads that and knows the tool — no docs needed. - **A validated render before any key exists:** `urlbox screenshot https://stripe.com --full-page --dry-run` comes back *"payload validated, no API call made."* The correct command, confirmed, with no credentials. - **Then it hits exactly one wall** — `code: auth`, "no API secret configured", with a link straight to where you get one. - **Add the key (\~30 seconds to grab it), and the first screenshot lands in under 6 seconds.** Nearly all of that minute is npm installing and you fetching your key. It works well, and the render itself is just seconds. The one thing the agent can't do for you is paste in your own credential — and that's deliberate: you decide when your credentials get written to disk, not the agent. ## How we built it for agents We took our cue from 37signals, who recently made [Basecamp agent-accessible](https://world.hey.com/dhh/basecamp-becomes-agent-accessible-3ae6b949) by pairing their API with a CLI and a set of agent skills. We applied the same idea to screenshots, with one goal throughout: make the tool as machine-friendly as possible. If you're building something an agent should be able to pick up cold, a few decisions made the biggest difference: - **Make every command self-describing.** `urlbox commands` and `--help` emit structured JSON, so an agent can *read* the tool instead of guessing at it. - **Give it a dry run.** `--dry-run` validates a request without spending anything, so an agent can confirm it built the right call before committing to it. - **Ship it as an agent skill.** One command — `urlbox skill install --target claude-code` — drops a skill file the agent auto-discovers, so it knows the tool from the first prompt (Cursor, Codex and opencode too). - **Don't hide the rest of the API.** The CLI passes any option straight through, so anything you can render through Urlbox, an agent can render for you. That's why "take every URL in this CSV and screenshot it into a folder" becomes a sentence, not a script. If you have a terminal, you can save screenshots. That's it. ## Frequently asked questions ### What is the Urlbox CLI? The Urlbox CLI is a command-line tool that calls the Urlbox screenshot API from your terminal. You can capture screenshots, PDFs, and videos of any URL with a single command, and it ships with an agent skill so AI coding agents can drive it directly. ### How do I take a screenshot from the command line? Install the CLI with `npm install -g @urlbox/cli`, run `urlbox auth` to add your API key, then run `urlbox screenshot https://example.com --output shot.png`. Once your key is set, the first screenshot lands in under 6 seconds. ### How fast can an AI agent start using the Urlbox CLI? In our timed cold-start test, going from never having seen the tool to a saved PNG took about a minute — roughly 30 seconds to install from npm, 30 to fetch an API key, and a few seconds for the render itself. ### Can the Urlbox CLI capture PDFs and videos too? Yes. Use `urlbox pdf <url> --output file.pdf` for PDFs and `urlbox video <url> --output file.mp4` for videos. The CLI passes any Urlbox API option straight through, so anything the API can render, the CLI can too. ### Which AI agents does the Urlbox CLI work with? Any agent that can run a terminal command can use it — it's just a CLI. To make it plug-and-play, we ship ready-made agent skills for Claude Code, Cursor, Codex, and opencode: run `urlbox skill install --target <your-agent>` and it knows the tool from the first prompt. Other agents can still drive it straight from `urlbox --help`. ## Try it — from your terminal or your agent This tool is still in its early days, and we'd love for you to share any issues you run into with us. You'll need an Urlbox account to render — [start a 7-day trial](https://urlbox.com/signup.md) — then install from [npm](https://www.npmjs.com/package/@urlbox/cli) or [GitHub](https://github.com/urlbox/urlbox-cli): ```sh npm install -g @urlbox/cli urlbox auth urlbox screenshot https://urlbox.com --output hello.png ``` Or just ask "Use the Urlbox CLI to screenshot this URL" and let your agent take it from there. --- # Why we changed our pricing > Last year we made the biggest change to Urlbox's pricing since we started in 2012. Source: https://urlbox.com/why-we-changed-our-pricing Last updated: 2024-05-31 --- ## The Ideal As a developer tool our ideal would be to charge in the same way as AWS. We like only paying for what we use at the end of the month. We'd love to be able to offer the same to our customers. But the reality is that huge amounts of AWS income comes from low-risk enterprise customers making long-term commitments. We want to be investing our time in improving our product, not negotiating contracts or implementing complex billing systems. Our old pricing was a compromise that didn't get the balance right. ## The Result We don't think it's a coincidence that since changing our prices we've: - Grown our customer base by 32% - Shot past 100 million successful renders per year. - Added revenue faster than ever before. - Kept revenue churn well under 2%. This has given us the confidence to grow our team of dedicated screenshot engineers without depending on outside funding. We think our new pricing works better for both us and our customers. ## Old Pricing Previously we charged a fixed monthly fee plus overage. There were three usage levels to choose from. Each of them had almost identical feature sets. The overage fee was charged at the end of a customer's billing period. It was OK for customers just getting started but the plans weren't a good fit for high-volume customers. That old pricing also left us carrying too much risk. When customers had high overage and then failed to pay we still had the infrastructure costs to pay. Increasing amounts of revenue coming from unpredictable overages also meant we couldn't plan like other SaaS. As a result there were times that we under-invested in infrastructure and the product. We don't have the resources of Amazon or a VC backed startup to balance this up. Since we changed our pricing we've seen some well funded, resource intensive developer tools make big changes to their billing pricing. Planet Scale discontinued their free tier. OpenAI now requires pre-payment. Vercel's "Improved infrastructure pricing" resulted in huge increases for many customers. Thankfully we've received positive feedback about the changes we've made. ## The Goal We wanted to achieve four things: - Fair. - Predictable. - Sustainable. - Simple. We think we've achieved three out of four. ### Fair We now have three different plans that align with the needs of different kinds of customers. LoFi is for customers who are primarily generating images from HTML they're developing themselves along with thumbnails of 3rd party sites. They rarely need our advanced features or significant amounts of support. HiFi is for customers who are taking screenshots of a mix of 3rd party websites and their own HTML. They want the accuracy and reliability Urlbox customers rave about. Ultra is for customers who want the best of the best in web imaging free from constraints. All features and priority support that feels like they've hired their own dedicated web rendering team. From side projects to enterprise solutions or somewhere between the two there's a plan for you. ### Predictable We now have public pricing that shows costs all the way up to 1 million renders per month. Pick a plan and use the slider on our pricing page. You'll be able to see exactly what you'll pay as you grow. The effective rate per render automatically drops by up to 68% as use increases. And there are further discounts for annual commitments. ### Sustainable It's easier for customers to grow with us. You don't have to make huge jumps in spend commitment to get the best price. You can see how the cost of Urlbox stacks up against creating your own in-house rendering team. We can invest faster in continuously improving the service. You can be even more confident in depending on us in the long term. ### Simple(ish) It's not as simple as having a flat rate per successful render. It's been a pain getting it working nicely in Stripe. But this approach is far simpler than many of the alternatives. You don't have to think in terms of bandwidth costs, storage costs, compute time or some form of abstract credit. We have built in incentives to continuously improve performance. While new customers have been signing up on these new plans for almost a year, and others have proactively switched, most are still on our legacy plans. Some have been on the same plan for over a decade! That means we have much more complexity in our billing code than we would like. We're now in the process of transitioning all customers to new pricing. We can't wait to delete our legacy billing code and get back to focusing on improving accuracy, performance and all the other things you'd expect from an API enterprises consider to be a critical part of their infrastructure. Overall we think this new pricing is a win-win for customers and us. We'd love to see more of the services we use introduce similar plans. --- # How to Capture Ad Screenshots And Automate Tear Sheets > In this article, you'll learn how to automatically create tear sheets of different ad campaigns and share them with your clients, regardless of the ads' placement. Source: https://urlbox.com/automated-screenshots/ads-and-tear-sheets Last updated: 2025-03-21 --- A tear sheet used to be a page cut or torn from a newspaper or magazine proving an advertisement was published. Used primarily by media buying agencies, tear sheets have evolved from physical pieces of paper to PDF documents. Today, most tear sheets are full-page screenshots of different websites, from news portals to blogs and even search engine pages. In this article, you'll learn how to automatically create tear sheets of different ad campaigns and share them with your clients, regardless of the ads' placement. These automated tear sheets provide essential proof of ad placement, streamline client reporting, and enable more efficient campaign analysis. ## Types of tear sheet automations You can automatically create tear sheets in different ways. You can leverage no-code tools like a [screenshot platform](https://urlbox.com/automated-screenshots.md) or use a low-code [screenshot API](https://urlbox.com/screenshot-api.md). Keep in mind that you have to take into consideration these two factors before picking the right solution: 1. How many programmatic ads you launch daily/weekly/monthly; 2. Your technical knowledge or your budget to hire a programmer. ### Comparison: No-Code vs API Approach | Feature | No-Code (Zapier + Urlbox) | API (Developer + Urlbox) | | ------------------------ | --------------------------- | --------------------------------- | | Setup time | 5 Minutes | 15 Minutes | | Technical skill required | Minimal | Moderate | | Cost for small volume | $ | $$ | | Cost for large volume | $$$ | $ | | Customization | Limited | Extensive | | Scalability | Up to \~100 screenshots/day | Unlimited | | Maintenance | Regular manual checks | Minimal once established | | Best for | Small agencies, beginners | Large agencies, high-volume needs | ## How to capture native ad screenshots with Zapier The fastest way to capture ad screenshots is by using Zapier and a screenshot service. For this example, I will use [Urlbox](https://urlbox.com/.md), as it's one of the most powerful and reliable services available. -> **Pro Tip:** For agencies tracking multiple campaigns, consider organizing your screenshots by client and campaign name in your folder structure to make reporting more efficient. Note: You can follow a previous article that covers [how to create a swipe file with Google Sheets and Zapier](https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier.md) if you want to screenshot ads on multiple pages and save the images. The workflow will be identical to that described in the article, but instead of calling your folder "Swipe file," you can give it another name, like "Ads Screenshots." For the following example, I will presume you publish native ads on certain websites at specific time intervals (daily, weekly, monthly). So follow along and learn how to automatically capture, save and share ad screenshots from a specific webpage. Before anything else, make sure you have created a premium Zapier account and a [Urlbox account](https://urlbox.com/pricing.md), both of which have a 7-day free trial period. ### Step 1 - Create a new Zap With all the accounts created, you can create your first Zap. Now go ahead and click on the "Schedule" option on the right part of the screen. This built-in tool developed by Zapier allows you to specify how often you want the Zap to run. Basically, how often do you want to screenshot the targeted webpage? ![Setting up a scheduled trigger in Zapier](/content/ads-and-tear-sheets/image3.jpg) You can pick whatever time interval works best for you, but I will go with "weekly". After you pick the frequency, you will have to set up the trigger. Zapier requires 2 parameters for the weekly trigger: - Day of the Week - Time of Day (if you haven't set up your time zone, then the default will be UTC, or GMT+00:00). Let's say I publish a new ad every Monday at 8:00 AM. ![Configuring the weekly schedule](/content/ads-and-tear-sheets/image5.jpg) Once you've configured the trigger, go ahead and save it. Next, you'll need to test it, and you can move on to the next step. ### Step 2 - Capture the screenshot with Urlbox Use the search bar to find the Urlbox connector. Make sure you give access to Zapier by login into your account. Pick the "Generate Screenshot From URL" event by clicking on the drop-down box, then click "Continue". Next, you'll have to select your account. Once that is done, you can continue setting up the actual Action. As stated before, this example revolves around a webpage that features a new ad each week. To keep things simple, I will use [markets.businessinsider.com](http://markets.businessinsider.com) as the example webpage. I will copy and paste that URL into the corresponding field. ![Setting up the URL to screenshot](/content/ads-and-tear-sheets/image6.jpg) Now it's time to select the output format. If you want to capture a [full page screenshot](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md), you should can pick any image file type or PDF, but if you want to capture just the hero section (above the fold), PNG or JPG are popular choices. I will pick PNG as I want my screenshot to reflect the ad banner below the main menu. Now you have to specify the viewport's width and height, basically the image's final dimension. I will go with the Full HD resolution of 1920 by 1080. ![Configuring screenshot dimensions](/content/ads-and-tear-sheets/image1.jpg) You can go the extra mile and configure Urlbox to take the screenshot only after all requests have finished. This will ensure the website is fully loaded before Urlbox screenshots it. ![Configuring advanced screenshot options](/content/ads-and-tear-sheets/image2.jpg) Once you are done, go ahead and test your action. If you followed all steps, then everything should be fine. Next, you'll need a place to save the screenshot. ### Step 3 - Save the image to Google Drive Now that you configured Zapier to capture a screenshot of a webpage every Monday at 9 AM, it's time to tell Zapier where the image should be saved. Note: I will use Google Drive in this example, but you can go with whatever cloud storage provider you want, as long as it has a Zapier connection. Select Google Drive as the Action App, then select Upload File as the Event. Follow the steps to connect your Google Account to Zapier. Once that is done, you have to set up the action. Pick the Drive where you want to save the file and the Parent Folder. You will have to manually create the folder on your Drive before it will appear in the drop-down list. Now for the last step, click on the File field, then search for "screenshot" in the search box. Click on the "Screenshot URL" variable. ![Selecting the screenshot URL variable](/content/ads-and-tear-sheets/image4.jpg) Simply click save and test the action. You are done! ### Optional - Step 4 - Change the file name If you want to keep things organized, you can change the final image name to include the date and time of the screenshot. This field accepts data and plain text, so we will combine these 2. 1. Start typing "Screenshot of", followed by a space. 2. Use the search bar to find the Input URL (this is the URL of the page you just screenshotted) and click on it. 3. Add another space, type in "captured on," and add one more space. 4. Use the search bar again to find the "Pretty Date" variable. ![Configuring the screenshot filename](/content/ads-and-tear-sheets/image7.jpg) The final image from this example will have the name: Screenshot of [https://markets.businessinsider.com/](https://markets.businessinsider.com/) captured on Sep 22, 2022. Remember, this method works best if you track a couple of dozen websites (20 to 30). But if you plan to scale your operation or run programmatic ads, you will need a dedicated service. ### Troubleshooting Common Issues When setting up your automated tear sheet workflow, you might encounter these common issues: 1. **Screenshots not capturing ads**: Ensure your timing is correct. Some ads load after a delay, so configure Urlbox to wait for all elements to load. 2. **Blank screenshots**: Check if the website uses anti-bot measures. You might need to [take stealth screenshots](https://urlbox.com/stealth-screenshots.md) or use a proxy. 3. **Missing elements**: If certain parts of the page aren't appearing, try increasing the viewport size or using full-page screenshots. 4. **Zap failures**: If your Zap stops working, check for URL changes on the target website or API quota limitations. ## Best way to capture programmatic ads screenshots You need to have advanced technical knowledge or the help of a developer if you want to use this method. But in the end, it will definitely pay off, especially since the costs of no-code tools can rise exponentially with the number of tasks you want to automate. Plus, you'll have to spend countless hours to keep everything working as expected. With that in mind, creating your own tool that can automatically capture ad screenshots makes sense. You can speed up the development process using a [screenshot service API](https://urlbox.com/screenshot-api.md), all while minimizing the number of development hours you have to invest in debugging. ### Urlbox - Best API to capture programmatic ads screenshots Urlbox is one of the best APIs to capture programmatic ad screenshots, built specifically as a fast, reliable way to generate high-quality screenshots. It works seamlessly with all major programming languages ([Python/Django](https://urlbox.com/website-screenshots-python.md), [C#](https://urlbox.com/website-screenshots-c-sharp.md), [Node.js](https://urlbox.com/7-ways-website-screenshots-nodejs-javascript.md)) and comes with a complete set of features, so you can make sure the final screenshot will look exactly as you want it to. Urlbox lets you configure how the page will be rendered before it generates the screenshot. Among others, here are some options and features people use the most: - Specify a custom User Agent - Generate retina quality images - Automatically hide or accept cookie banners - Tunnel the request through a proxy of your choice - Capture full page screenshots that support infinite scroll - Set a delay before capturing the screenshot (either in ms or on specific events). In addition, you can instruct Urlbox to save the final image in any format you want (PNG, JPG, [PDF](https://urlbox.com/url-to-pdf.md), WEBP or AVIF). Note: You can visit the [official documentation](https://urlbox.com/docs.md) to better understand how Urlbox works. As mentioned before, once you start scaling, your costs will skyrocket, but that's not the case with Urlbox. You'll get a [7-day free trial](https://urlbox.com/pricing.md) when you first sign up regardless of the plan you choose (no credit card required), as your usage scales you'll get automatic volume discounts. Custom pricing and dedicated rendering clusters can further reduce costs when you're generating millions of screenshots per month. Depending on the scale of your operation, you can [pick a plan](https://urlbox.com/pricing.md) that works for you. ## What is the best way to capture ad screenshots and automatically create tear sheets? Based on everything I have covered, you should clearly know what would work best for you. Ultimately, it all depends on how many ads you publish monthly, how many websites you have, and how much you want to invest. If you are starting out or running a small media buying agency (managing under 50 campaigns), then you'll be better off going with the no-code method. This approach requires minimal technical knowledge and can be set up in under an hour. For medium-sized agencies (50-200 campaigns), consider a hybrid approach where you use Zapier for simple screenshots while implementing the API for more complex needs. If you're managing hundreds or thousands of campaigns, you should definitely invest in a dedicated screenshot service API with Urlbox. The initial development cost will be quickly offset by the efficiency gains and scalability. ## Frequently Asked Questions **Q: How often should I capture ad screenshots?** A: For most campaigns, daily captures are sufficient. For high-value or short-duration campaigns, consider multiple captures per day. **Q: Can I capture ads on sites that require login?** A: Yes, Urlbox has a guid to [taking screenshots behind login](https://urlbox.com/screenshot-behind-login.md). **Q: How do I handle dynamic ads that change based on the viewer?** A: Use Urlbox's custom headers and cookies options to simulate specific user profiles when capturing screenshots. **Q: Can I automatically compile multiple screenshots into a single tear sheet?** A: Yes, you can use the Urlbox PDF generation feature to compile multiple screenshots, or use tools like Google Docs API to create custom reports. **Q: How do I ensure I'm capturing the actual ad and not a placeholder?** A: Use Urlbox's delay options to ensure the page fully loads, or set up element detection to wait for specific ad elements to appear. --- # How AI is Enhancing Web Monitoring > Explore how AI is revolutionizing the web monitoring process, offering new capabilities and insights at a scale that was previously unimaginable. Source: https://urlbox.com/ai-web-monitoring Last updated: 2023-09-12 --- Up until recent years, traditional web monitoring methods involved manual checks, automated scripts, and using third-party services that provide insights into a website’s health and performance. These methods have proven invaluable in helping organizations maintain their online presence and protect their digital assets. These methods are still being used today but have increasing limitations. Manual monitoring is time-consuming and prone to human error, while automated scripts can only detect predefined issues. Besides, the sheer volume of data generated by websites can be overwhelming, making it difficult to identify and address problems in real time. In this article, we'll explore how AI is revolutionizing the web monitoring process, offering new capabilities and insights that were previously unimaginable. From price tracking to brand management and regulatory updates monitoring, AI promises to transform the way we manage and optimize our online presence. ## The impact of AI on web monitoring AI's ability to process vast amounts of data quickly and accurately has made it possible to monitor websites in real time, identifying issues and anomalies as they occur. AI-powered monitoring tools can also learn from past data and provide useful information on the potential issues related to website performance. The development of AI shows no signs of slowing down, and it’s bringing a host of new technologies to the forefront of web monitoring. These technologies are transforming the way we monitor websites and offer us new insights into optimizing their performance. ## Key AI technologies powering web monitoring Let’s explore some of the key AI technologies that are powering this revolution in web monitoring. ### Machine learning and pattern recognition By analyzing vast datasets, machine learning algorithms can detect subtle patterns and anomalies in web content changes that might go unnoticed by traditional monitoring tools. These algorithms continuously learn from new data, refining their predictions and making them more accurate over time. This ability to adapt and evolve allows machine learning models to proactively identify potential issues, from unexpected traffic spikes to subtle changes in user behavior. ### Natural language processing (NLP) Natural language processing (NLP), another subset of AI, helps you understand and categorize textual changes on the web. NLP algorithms can analyze a webpage, identifying changes in content, sentiment, or context. Take, for example, ChatGPT, one of the most advanced language processing tools. It can not only identify the text changes on a web page but also point out code changes and even functionality changes. ### Image recognition and analysis AI-driven image recognition and analysis tools are revolutionizing the way we monitor visual elements online. They can detect changes in images, identify objects, and even interpret emotions in photographs. For instance, if a brand updates its logo or product images, AI can detect this change and assess its impact on user engagement. And, by analyzing this visual content, AI can provide insights into user preferences, helping businesses tailor their visual strategy to better resonate with their audience. ## Benefits of AI-driven web monitoring To optimize their online presence, companies take advantage of AI-driven web monitoring tools because of their new capabilities and insights that were previously very hard to get. Here are some key advantages that businesses can gain using AI in web monitoring. ### Real-time updates and alerts As mentioned previously, traditional web monitoring methods often involve manual checks or automated scripts that run at predefined intervals. In contrast, AI-powered tools can monitor websites continuously, detecting and analyzing changes as they occur. This real-time monitoring minimizes the impact of problems such as security breaches, server overloads, or content errors. What’s even more useful, AI-driven web monitoring tools can be configured to send instant notifications when significant changes occur. ### Predictive analysis Predictive analytics is another key benefit of AI-driven web monitoring. AI-powered tools can analyze historical data and patterns to forecast potential future changes. Thus, you can anticipate and prepare for potential issues, such as traffic spikes, server overloads, or security breaches. Predictive analytics also provide insights into optimizing website performance, helping organizations identify areas for improvement and implement changes that enhance the user experience. ## Case studies: AI in action Artificial Intelligence is revolutionizing various sectors, from e-commerce and regulatory compliance to brand management. Here are just a few examples of how businesses leverage AI as a strategic asset. ### Tracking product changes E-commerce companies use AI-driven web monitoring tools to track updates on platforms like Amazon. For example, retailers can use AI to [monitor price changes](https://urlbox.com/track-product-prices.md), product listings, and customer reviews in real-time, which can be useful in adjusting pricing strategies and identifying market trends. This is especially useful during major sales events, such as Black Friday or Christmas, and gives an unfair advantage to companies that want to remain competitive and seize potential sales opportunities. ### Regulatory updates monitoring Companies operating in regulated industries face the constant challenge of staying compliant with ever-evolving regulations. AI web monitoring tools can scan regulatory websites, news sources, and official documents to detect any changes in regulations. A typical case is the banking sector, which is subject to a myriad of rules that can change frequently. Similarly, with changes in the GDPR in the EU, businesses had to ensure they were compliant with new data protection standards. ### Brand reputation management It’s no secret that brands need to constantly monitor their mentions across the web, especially within a competitive market. AI-driven tools have made this task more manageable and effective. They can detect mentions of a brand, categorize the sentiment (positive, negative, or neutral), and provide real-time alerts. This strategy enables brands to respond swiftly to negative feedback, address concerns, and advocate for a positive brand image. ## Challenges and limitations of AI in web monitoring AI, like any technology, is not without error. Its efficacy is often tied to the quality and quantity of data it’s trained on. Inaccurate or biased data can lead to flawed insights, which can have significant repercussions for companies. That being so, as AI continues to evolve, there’s a growing concern about its potential to over-automate processes. Over-reliance on AI-driven insights without human oversight can lead to missed opportunities or misinterpretations. For the most part, this holds true when we talk about data privacy concerns. ### Data privacy concerns AI-driven web monitoring tools do have the capability to gather vast amounts of data, which means that this raises significant ethical considerations and potential risks, especially concerning data privacy. As AI tools scan and analyze web content, there's a risk of inadvertently collecting personal or sensitive information. This poses ethical dilemmas and can also lead to legal repercussions, especially in regions with stringent data protection regulations. It's imperative for businesses to ensure vigorous data protection measures when employing AI-driven web monitoring tools. This not only safeguards the interests of users but also protects businesses from potential legal and reputational damage. Here are some important points to keep in mind regarding ethical considerations and potential risks: 1. Inadvertent data collection: Risk of gathering personal or sensitive information without consent. 2. Data security: Potential breaches in the storage and processing of vast amounts of data. 3. Bias and discrimination: AI algorithms can perpetuate existing biases if trained on skewed data. 4. Lack of transparency: Difficulty in understanding the reasoning behind AI-driven insights. 5. Over-reliance on automation: Potential to miss nuances or context that a human might catch. ## Conclusion: Embracing the AI revolution The advent of AI in web monitoring has undeniably shifted the paradigm, offering capabilities far beyond what traditional methods could achieve. It's clear that as this technology continues to advance, it will become an increasingly integral part of web monitoring strategies, helping businesses to be more proactive rather than reactive. However, it's crucial to remember that AI is not a silver bullet. While it offers unprecedented advantages, there are also challenges and limitations to consider, such as data privacy concerns and the potential for over-automation. The key to successfully leveraging AI in web monitoring will be to combine its computational power with human oversight, ensuring that ethical considerations and potential risks are adequately addressed. This balanced approach will not only optimize web performance but also build a more secure and ethical digital landscape. --- # How SaaS Companies Can Automate Documentation with Screenshots > Explore the benefits of automating documentation with screenshots and how the Urlbox screenshot service API can help. Source: https://urlbox.com/automated-screenshots/automate-documentation Last updated: 2023-04-12 --- In the fast-paced world of SaaS products, documentation plays a pivotal role in ensuring seamless user onboarding, customer support, product adoption, and client retention. However, keeping it up-to-date and consistent can be discouraging for most companies, especially when frequent updates and feature additions are part of your growth strategy. Finding efficient solutions for maintaining high-quality documentation is extremely important in such a dynamic environment. This article will explore the benefits of automating documentation with screenshots and how the Urlbox screenshot service API can be a game-changer for your SaaS. ## What Is Product Documentation Product documentation refers to a comprehensive set of materials that provide information about a product, its features, and how to use it effectively. These materials guide users, helping them understand the product's functionalities, troubleshoot issues, and maximize its potential. The primary goal of product documentation is to enhance user experience and satisfaction by offering clear and concise information. It can be divided into different types based on their purpose: 1. User guides or manuals: These documents provide step-by-step instructions on using a product, covering its features, functions, and settings. They are designed to help users easily navigate the product and address common use cases. 2. Technical documentation: This type of documentation delves into the technical details of a product, such as system requirements, installation procedures, and API specifications. It is primarily intended for developers, IT professionals, or advanced users who require in-depth knowledge of the product's inner workings. 3. Release notes or changelogs: These documents communicate updates, new features, bug fixes, and other changes made to a product. They help users stay informed about product improvements and any necessary adjustments to their workflows. 4. Knowledge base articles or FAQs: These resources offer quick answers to frequently asked questions and solutions to common issues. They provide users with instant access to the information they need, reducing the load on customer support teams. 5. Tutorials or how-to guides: These materials provide step-by-step instructions and best practices for specific tasks or workflows, enabling users to learn and apply new skills effectively. ## Why Is Documentation Important Above anything else, comprehensive and up-to-date documentation can ensure a smoother user experience and reap numerous benefits. Effective documentation simplifies the user onboarding process, helping your customers quickly get familiar with your software. By providing them with easy access to information, you'll help them transition from novice to proficient users, ensuring they can effectively leverage your platform. Well-structured documentation can also serve as a valuable self-help resource. It allows users to troubleshoot common issues and find answers to frequently asked questions. This not only reduces the burden on your customer support team but also fosters a sense of autonomy and satisfaction among users. Furthermore, thorough documentation promotes product adoption by making users aware of all available features and capabilities, helping them maximize the benefits of your software. High-quality, up-to-date documentation also contributes to client retention, demonstrating your company's commitment to customer success. You can foster trust and loyalty and improve long-term client relationships by providing the necessary resources to support your users. Moreover, documentation also plays a role in internal knowledge sharing, making it easier for your teams to collaborate, share information, and maintain consistency in messaging and support. Clear and comprehensive documentation can help demonstrate compliance with industry standards or protect your company in case of disputes. Your SaaS documentation directly impacts user experience, customer satisfaction, product adoption, and long-term client relationships. ## Benefits of Using Screenshots In Your SaaS Documentation The saying "a picture is worth a thousand words" holds true when it comes to improving your SaaS documentation. Clear and accurate images showcasing your application in action can greatly simplify explanations and make it easier for users to navigate your software. Instead of writing blocks of text to explain how your product works, aim for visual representations of your software's UI. This will allow users to quickly grasp the context and layout of the features they are learning about, ultimately leading to a more enjoyable and efficient learning experience. And because humans are predominantly visual learners, your users will find it easier to remember how your product works if they see exactly what they have to do and where they must click. Screenshots can also use be used through the onboarding experience of your product. You can use parts of your documentation to teach new users how they can leverage your product. If you continually update your UI or add new features and functionalities, you will need to constantly capture new screenshots and update your documentation, which can be tedious. That's where a screenshot generator API comes into play. You can configure it to capture screenshots of your product, such as full-page screenshots or just of a single element, and automatically upload them into your documentation. This will help you save time while keeping your documentation up-to-date and engaging. ## How Urlbox Screenshot Service API Helps You Automate Documentation The Urlbox API is a great tool for automating your SaaS documentation. It offers a wide range of features, such as rendering high-quality screenshots, customizable dimensions, support for multiple formats, and the ability to capture full-length or viewport-sized images. The API boasts excellent performance, with fast rendering times and caching capabilities. Integrating the Urlbox API into your SaaS documentation process is a breeze. To get started, simply utilize the API endpoints to generate screenshots programmatically, which can then be embedded into your documentation. This approach enables automatic updates of visuals whenever there are any changes in your software's user interface. ## How to Automate Screenshots With Urlbox There are various ways you can configure the Urlbox API to start capturing screenshots automatically. By far, the fastest way is to use a GET request. Here's an example of how this request looks like: [https://api.urlbox.com/v1/api-key/format?options](https://api.urlbox.com/v1/api-key/format?options) To get your API key, you must sign up for an account. All plans come with a 7-day free trial, so you can give Urlbox a try before committing to it. The format refers to the output format of the screenshot and can be either one of these: PNG, JPEG, AVIF, WEBP, PDF, SVG, or HTML. Last but not least, the options parameter must be replaced by a query string featuring all of the options you want to set. Urlbox is truly comprehensive, which means it provides a plethora of different prerendering options that allow you to configure how the screenshot will be captured: - Basic options include the width and height of your final image, the area you want to screenshot based on a specific selector, or capturing a full-page screenshot. - Blocking Options: such as automatically accepting cookies or hiding cookie banners altogether. - Request Options: allowing you to configure the browser before navigating to the URL. These include options for setting up proxy servers, headers, cookies, etc. - Page Options allow you to modify the page before the screenshot is captured. You can find the [complete set of configuration options](https://urlbox.com/docs/options.md) right in the [API documentation](https://urlbox.com/docs.md). If you want to implement Urlbox into your app, then you should know that it works with all major programming languages. ## Start Automating Documentation With Screenshots Automating your SaaS company's documentation with screenshots can significantly improve user experience and streamline your documentation process. By incorporating clear visuals, you can simplify explanations and make it easier for users to navigate your software. Sign up for Urlbox and start automating all your documentation screenshots in no time. --- # Automate website screenshots on a schedule > Schedule website screenshots hourly, daily, weekly, monthly, yearly, or on a specific date with Urlbox screenshot API and Zapier. Source: https://urlbox.com/automated-screenshots/automate-website-screenshots-schedule Last updated: 2025-03-21 --- Ever wanted to check a website every hour, day, week or month? Using Urlbox [screenshot API](https://urlbox.com/screenshot-api.md) with our new Zapier integration, you can automate website screenshots and schedule them hourly, daily, weekly or to be taken at a specific time. This article will take you through the necessary steps to get started automating screenshots with Urlbox and Zapier. In this example we will schedule hourly screenshots of bbc.com and push them to a Google Drive folder. ![zapier overview](/content/zapier-schedule/zapier-overview.png) ## Why schedule screenshots? Perhaps you want to track the price of a certain product over time, or the performance of some stock, or you want to check the google SERP results for some keywords periodically. Maybe taking a screenshot of your competitors website each week may give some insights into what direction they are taking. Another typical use-case of scheduling website screenshots is for archival purposes. For example, you might want to take a screenshot of a website every hour, every day, every week, or every month. \~> What is Zapier? Zapier is a platform that allows you to connect API's such as Urlbox's website screenshot API with 1000's of other platforms and API's to create powerful automations and workflows. You do this by creating Zap's which we will see an example of below. ## How to schedule screenshots? The easiest way to schedule website screenshots is to use a [website screenshot API](https://urlbox.com/screenshot-api.md) like urlbox. Using the [Urlbox Zapier integration](https://zapier.com/apps/urlbox/integrations), alongside Zapier's schedule zap, you can schedule screenshots to be taken hourly, daily, weekly and at specific times. -> Apart from scheduling, Zapier also allows you to make screenshot requests from other triggers. For example, when a new blog post is published to a CMS, you could trigger a new screenshot request. Or when a new row is added to a spreadsheet in Google Sheets or Airtable. ## Prerequisites In order to follow the rest of the article, you'll need: - A Urlbox account, for taking the screenshots - A Zapier account, for scheduling the screenshots - Optionally, a Google account to upload the scheduled screenshots to a Google Drive folder - You can also push the screenshots to a Dropbox, Amazon S3 or any other cloud storage account that integrates with Zapier. ## Getting started with scheduled screenshots To get started, first sign up to Urlbox and create an account. Plans start at $19/month and include 2,000 successful screenshots and Zapier integration. ![urlbox signup](/content/zapier-schedule/urlbox-signup.png) Once you have signed up with Urlbox, you should take a note of your API key and API secret: ![urlbox api key](/content/zapier-schedule/urlbox-api-key.png) Then, signup or login to your Zapier account, and once on the Zapier dashboard, click the big plus icon to create a zap. ![zapier search urlbox](/content/zapier-schedule/zapier-create-urlbox-zap.png) ## Create a scheduled screenshot zap Great, now we should see the zap editor open. First of all let's name our zap, let's go with something like 'Screenshot bbc.com every hour'. Every zap needs a 'trigger', something which will initiate the zap and cause it to run. For this, we'll use the zapier built-in 'schedule' trigger: ![zapier schedule trigger](/content/zapier-schedule/zapier-schedule-zap.png) Now in the trigger options, select 'Every Hour' from the Trigger Event dropdown: ![zapier hourly](/content/zapier-schedule/zapier-hourly.png) Click continue and the next step will ask whether you want the zap to trigger on weekends or not, and you can leave this as is. ![zapier weekends option](/content/zapier-schedule/zapier-weekends.png) Now the trigger editor will ask you to test the trigger. This may seem a bit strange since we haven't hooked the trigger up to anything yet, but just go with it and click 'Test Trigger'. ![zapier test trigger](/content/zapier-schedule/zapier-test-trigger.png) Zapier finds an hour that satisfies the trigger. Click continue and you'll see the next step, which is to choose the action to be executed when the trigger is fired. ## Choosing to take a screenshot when the trigger is fired In the search box, search for 'urlbox' and select the Urlbox integration: ![zapier urlbox action](/content/zapier-schedule/zapier-urlbox-action.png) Now choose 'Generate Screenshot from URL' from the Action Event dropdown: ![zapier action screenshot](/content/zapier-schedule/zapier-action-screenshot.png) and click Continue. ## Connecting to Urlbox Screenshot API This is where you connect your Urlbox account to your Zapier zap, click the 'Sign in to Urlbox' button: ![zapier urlbox signin](/content/zapier-schedule/zapier-signin-urlbox.png) A new window will pop-up asking for your Urlbox **secret** key, which you were given when you signed up with Urlbox earlier: ![zapier urlbox secret](/content/zapier-schedule/zapier-urlbox-secret.png) When you've pasted in your secret key and clicked on the 'Yes, Continue' button, the pop-up should close and on the zap editor you will see your account details filled in: ![zapier urlbox success](/content/zapier-schedule/zapier-urlbox-account-success.png) Click Continue now, and you will progress to the next set of options that allow you to configure the settings for the screenshot that urlbox will take on a schedule. ## Configuring screenshot options for Urlbox For this example, since we want to take an hourly screenshot of bbc.com, we will set the Url field to 'bbc.com'. We just want a normal viewport screenshot, rather than a full-page screenshot, so we will most settings to their defaults. If you do want to take full page screenshots on a schedule, then this is the screen where you can configure all of the options that will be used when urlbox takes the screenshot every day: ![zapier urlbox screenshot options](/content/zapier-schedule/zapier-urlbox-fields.png) In the example, we have set the [block\_ads](https://urlbox.com/docs/options.md#block_ads) option to true, [hide\_cookie\_banners](https://urlbox.com/docs/options.md#hide_cookie_banners) to true in order to hide cookie banners from the screenshot, and we have set the [retina](https://urlbox.com/docs/options.md#retina) option to true in order to take a high dpi screenshot at 2x resolution. -> If any option is missing from the zapier integration, that you require for your screenshots, please do let us know and we will update the zapier integration. Once you're happy with your screenshot options, click the continue button to progress to the next step. ## Sending a test screenshot The next step asks you to send a test screenshot to urlbox, you can check that all of the options are configured correctly before clicking on Test & Continue: ![zapier test screenshot](/content/zapier-schedule/zapier-test-urlbox.png) Once you click on Test & Continue, Zapier will send a one-off request to urlbox in order to test that everything is working smoothly: ![zapier test success](/content/zapier-schedule/zapier-test-success.png) From here you can click 'Turn on Zap' and your zap will be ready to go. Every hour from now on, it will make a request to urlbox to take a screenshot of bbc.com. This is great and all, but what if we want to store our screenshots somewhere, or save them to permanent cloud storage? The screenshot url that urlbox returns is only valid for 30 days, so we'll want to add an extra step to our zap to store the screenshot somewhere else. ## Storing the screenshot permanently There are many places we can store the screenshot, for example we could save it to an amazon S3 bucket using the S3 zapier integration, or we could upload the screenshot to Dropbox. For our example, we will choose to store the screenshot to Google Drive, but the process is very similar for any zapier action that allows you to upload a file from a URL. To upload the screenshot to Google Drive, we'll click the plus button below our Urlbox action and search for the Google Drive action. We'll then choose 'Upload File' from the Action Event dropdown: ![zapier google drive action](/content/zapier-schedule/zapier-urlbox-google-drive.png) Click continue. Now we'll be asked to sign in to Google Drive: ![zapier google drive signin](/content/zapier-schedule/zapier-google-drive-signin.png) Once you click the 'Sign in to Google Drive' button, another pop up window will open and you'll be taken through the steps to sign in to your Google account: ![zapier google account](/content/zapier-schedule/zapier-google-oauth.png) Make sure you're happy for Zapier to access your Google account, and with the permissions it has over your Google Drive files, then click Allow. ![zapier google drive permissions](/content/zapier-schedule/zapier-google-permissions.png) Now that your Google Drive account is linked to the Zapier zap, you can click Continue to move to the next step. Now the zap editor will allow you to configure the settings for the Google Drive action. ## Configuring the screenshot location in Google Drive Here you can choose which particular Drive and folder you want to upload the screenshot to. The most important part is to ensure that you map the **Screenshot URL** output field from Urlbox to the **File** input field of the Google Drive action: ![zapier-google-upload](/content/zapier-schedule/zapier-google-uploadurl.png) \~> The Screenshot URL shown in the zap editor will be a dummy url to a dummy image. This is sample data that is used to setup the zap. When the zap is run it will be replaced with an actual screenshot URL. Next we should choose a filename for the file when it is saved in Google Drive. We can use a combination of outputs from the Schedule action and the Urlbox action to generate a dynamic filename that includes the url and the time that the file was taken. Based on the screenshot below, the filename will be roughly: ```zsh render_{url}_{day}_{month}_{year}:{hour}:{minute}:{second}.png ``` which based on the time and url used will become: ```zsh render_bbc.com_7_2_2022_5:38:3.png ``` ![zapier dynamic name](/content/zapier-schedule/zapier-dynamic-name.png) Almost done! Now we can run the final test, to ensure that everything is working as expected: ![zapier final test](/content/zapier-schedule/zapier-final-test.png) Great Success! If we now check in our google drive folder, we should see the screenshot from the zapier test: ![zapier google drive saved](/content/zapier-schedule/zapier-google-drive-saved.png) Ok, finally let's turn the zap on. Leave the zap running for a few hours, and then check your Google Drive folder. You should see one screenshot for every hour you left the zap running: ![many bbc screenshots](/content/zapier-schedule/many-bbc-screenshots.png) ## Conclusion In this article we learned how to capture hourly screenshots of a website, using bbc.com as our example. This kind of automation is useful for capturing screenshots of websites that change frequently over time. Automating screenshots in this way is made possible using the [Urlbox screenshot API](https://urlbox.com/screenshot-api.md).

HTML to Image Tools - The Ultimate List > HTML to PNG screenshot converters are a dime a dozen, but which one will help you generate the screenshots you need? Here's a list of the five best HTML to image tools. Source: https://urlbox.com/automated-screenshots/html-to-png Last updated: 2025-03-21 --- At first glance, it might seem like there is no point in using a dedicated service to convert HTML to PNG at scale when you can easily do that yourself in-house. However, there are several reasons why you may want to use a service instead of implementing the conversion process on your own. These include: using generated screenshots within your content or marketing assets, capturing screenshots at scale, fast, or monitoring websites for changes without the headache of maintenance or scaling. HTML to PNG screenshot converters are a dime a dozen, but which one will help you generate the screenshots you need? There are different options available, each with its pros and cons. In this post, we’ve reviewed the features of the top 5 converters currently available. Here’s what we’ve found. ## What is an HTML to PNG converter? An HTML to PNG converter is a tool that captures a webpage as an image file. This image can be either in PNG or JPEG format. The image is a static representation of the webpage, and no updates will be made to the image automatically if changes occur on the website. The URL of the webpage is required to take its screenshot as an image file (either PNG or JPEG). ## The ultimate list of HTML to PNG converters ### 1.[Urlbox](https://urlbox.com/.md) Urlbox is a website [screenshot API](https://urlbox.com/screenshot-api.md) that allows you to take full-page, high-quality images from any URL in PNG or JPG file format. The Urlbox API is super fast and easy to use, and it offers developer-friendly features such as automatic pagination, custom CSS stylesheets, and responsive rendering. Urlbox has excellent security practices, including SSL encryption and IP whitelisting. It also has timeouts that automatically return a screenshot if the webpage takes too long to load. The Urlbox API can be used on any website or app, allowing you to generate screenshots perfect for marketing emails, app stores, or anywhere else that requires screenshots of your website. It even caters to dynamic content with options for headless browsers like Chrome Puppeteer. #### Main features ##### 1. Block Ads ![](/content/best-html-to-png-converters/image3.png) Have you ever been scrolling through your website and realized that the scrolling is more like watching a slideshow than actually being able to read anything? This is because ads and images on many sites are loaded asynchronously with the rest of the content, making for a terrible user experience. This often happens when viewing your website on a mobile device or tablet. Urlbox solves this problem by allowing you to [block requests](https://urlbox.com/docs/options.md#block_ads) from popular advertising networks from loading when generating your screenshot. Urlbox automatically blocks known advertising network URLs while leaving other image requests alone. ##### 2. Bypass Captchas Whether submitting a request or just browsing a website, we all had to enter a CAPTCHA code at some point—that's the series of letters and numbers that websites show to prove that you're a human being. But what if there was a tool that automatically entered these codes for you? As it turns out, there is—Urlbox makes it easy to bypass any CAPTCHAs on your website screenshots with just one click. Urlbox will automatically attempt to solve and bypass any CAPTCHAs that are shown before generating your website screenshots. ##### 3. Click Accept ![](/content/best-html-to-png-converters/image1.png) Have you ever found yourself staring at a cookie banner, wondering what the point was? Why are you supposed to "accept" or "decline" these things? You may not be sure what's happening, but it's very likely that the way your browser is configured, your computer will remember to show it every time whenever you visit a site with a cookie banner. To make your screenshots clean and clutter-free, Urlbox can automatically [dismiss the cookie banners](https://urlbox.com/docs/options.md#click_accept) on any site you're using it on. #### How to capture screenshots with Urlbox The GET API is the quickest way to get started with Urlbox. It's perfect for one-off requests where you need an image immediately. With this API, you can picture the request as a box you're willing to wait for before continuing (your script won't do anything else until it's processed). If you are making many synchronous requests, you should consider using the asynchronous API to avoid timeouts. Note: Urlbox is our product. We’re proud to be a premium provider of website screenshots,and we take pride in our excellent customer support. Transform the way you generate website screenshots and try Urlbox [here](https://urlbox.com/pricing.md). ### 2.[Screenshotlayer](https://screenshotlayer.com/) With Screenshotlayer, screenshots are generated through the Screenshotlayer API, which allows for instant delivery of high-resolution images through a simple REST API interface. Screenshotlayer is particularly interested in ensuring that its API is supported with enough bandwidth for any use case. They want it to be scalable, extensible, and fast - and they want users to take advantage of these qualities without worrying about them. In addition to instant delivery and programmatic control, Screenshotlayer is blazingly fast—it takes just seconds for screenshots to be generated and delivered, no matter the file format. This speed is accomplished by leveraging Amazon Web Services (AWS) and other cloud services such as S3 and CloudFront. And because Screenshotlayer leverages AWS, costs are predictable—there are no upfront fees or long-term contracts—and you have the option of paying only for what you use. ### 3. [Stilio](https://www.stillio.com/) Stilio is a free tool that lets you convert any website to a jpeg image. You can then save the jpeg, upload it to your computer, and send images directly through email. Stillio is a fully customizable web-scraping tool that can be set to make a website screenshot at any desired frequency.

[HTML2Canvas](https://html2canvas.hertzen.com/) This one is a bit different from the others on our list. It’s an open-source library that is free to use, and it has some cool features. However, it’s not a standalone tool and requires coding knowledge. So this section won’t be for everyone here today. If you are a developer or want to learn web development, read on! HTML2Canvas is one of the best HTML to PNG converters you can find for web developers on GitHub. Amongst its many good qualities, it’s fast enough to capture pages with lots of unique content without slowing down your page or taking too long to render images (as long as your computer isn’t old). ### 5. [URL2PNG](https://www.url2png.com/) URL2PNG is a hosted solution for taking high-resolution screenshots of web pages. It has a simple API that lets you take a screenshot of any URL, which can be helpful for many purposes: - Publishing live screenshots of web pages in your blog or website - Creating mockups of web pages without having to open them up in Photoshop - Include a thumbnail preview of web pages on your site, just like Google does with their search results and Google Image Search. ## How to convert HTML to PNG using Python? You can convert HTML to PNG using Python by picking a tool that's designed for exactly that task. Python is a popular programming language, and it's great for quickly processing HTML into pictures. There are several options at your disposal, and each of them works with the same steps: - Install the Python Imaging Library (PIL) - Use PIL’s ImageGrab module to grab the screen's contents or any window. - Use PIL’s Image module to save the image to a file. Here’s how to [generate website screenshots using Python](https://urlbox.com/screenshot-api/python.md). ## How to choose the right HTML to PNG converter Choosing the best HTML to PNG converter is important because it dictates the quality of your output and how fast you can scale. When thinking about what kind of tool you need, it helps to break down your requirements into three key components: - How easy is it to integrate into my application or workflow? How much engineering effort do I need to put behind this? - What is the quality of the output? Is it high enough that no one would be able to tell that this page was rendered automatically? - How fast is this thing? Can it keep up with my traffic or speed requirements? Does it support concurrent requests? The answers to these questions will help you find a tool that's powerful enough for your needs. When choosing an HTML to PNG Converter, you should look for features like: - Choice of image formats. Some converters will allow you to output in various formats besides PNG, including PDF, JPG, and GIF. - API or downloadable tool. An API (Application Programming Interface) is a web service that converts HTML to an image. A downloadable tool is a program that runs locally on your computer (also known as "offline") and converts HTML content into an image. - Ability to select from different browsers. Suppose you use multiple browsers such as Chrome, Firefox, Edge, or Internet Explorer. In that case, it's helpful if your converter allows you to convert the same HTML for different browsers simultaneously with one request. This helps you compare how other browsers render the same content so you can find issues before your clients do! ## See if Urlbox is the right HTML to PNG converter for you ![](/content/best-html-to-png-converters/image2.png) Urlbox should be your go-to HTML to image converter tool if you’re looking for: - customizable resolution, viewport, and user agent - rendering of interactive content - support for JavaScript, cookies, authentication, and headers - ability to render hidden content - ability to render content with flashing, blinking, or hover effects. Urlbox also has robust API documentation and support for proxies, so you can start generating website screenshots right away.

Source: https://urlbox.com/automated-screenshots/capture-screenshots-from-urls-google-sheets Last updated: 2025-03-21 --- ![screenshot urls](/content/google-sheets-screenshots/screenshot-urls.png) If you have a list of URLs in Google Sheets and want to capture screenshots of them, this guide will walk you through how to do it. The workflow will be: 1. Setting up a list of URLs in Google Sheets 2. Creating a zap in Zapier which will carry out the following steps: For each new or updated row in the Google Sheet: 1. Read the URL from the URL column 2. Capture a screenshot of the URL using the Urlbox [screenshot API](https://urlbox.com/screenshot-api.md) with various options. 3. Save the returned screenshot to a folder in Google Drive. 4. Update the row in the Google Sheet with the URL of the screenshot in Google Drive. 3. Test that the zap is working, and works when we add a new URL row to the Google Sheet. ## Setting up list of URLs in Google Sheets The first part is setting up a list of URLs in Google Sheets. For this example, I asked chatGPT for a list of URL's of the top Saas products, in csv format, so that I can quickly copy the URLs into a new Google Sheet. It's important to ensure that the list of URLs is in one column and each URL is on a separate row. Create a heading row at the top and label the column of URLs as "URL" as this will make it easier to reference in the zap. Save your sheet with a name that you can remember, as we will reference it in the next step. I saved the spreadsheet as "List of URLs". ![Google Sheet with a list of URLs](/content/google-sheets-screenshots/list-of-urls.png) ## Creating the zap in zapier The next step is to create a zap in Zapier. Zapier is a tool that allows you to connect different apps together and create automated workflows between them. In this case, we will be connecting Google Sheets and Urlbox. The first step in the zap is the trigger, for this we will use the "New or Updated Spreadsheet Row" trigger in Google Sheets. This will trigger the zap whenever a new row is added to the Google Sheet, or an existing row is updated. ![Google Sheets trigger in Zapier](/content/google-sheets-screenshots/google-sheets-trigger.png) Next, we need to connect the zap to the Google Sheet. We will need to connect to the Google account that owns the Google Sheet, and then select the Google Sheet and worksheet that we want to use. ![Google Sheets setup](/content/google-sheets-screenshots/google-sheets-setup.png) Ensure you set the correct spreadsheet and worksheet from the first step, that contains your URLs. For trigger column, you can choose to select a certain column that when updated will trigger the zap, or you can leave it as the default 'any\_column', and the zap will be triggered whenever any column is updated. Now click continue, and you will be prompted to test the trigger. Click the test trigger button, and Zapier will return a sample of rows from the sheet. You can choose one row to continue setting up the zap. Click continue with selected record. ## Adding the Urlbox screenshot action The next step is to add the Urlbox action to the zap, which will take the URL from the row in the Google Sheet, and capture a screenshot of it. In the search box, type Urlbox, and select the Urlbox action, and then choose the "Generate Screenshot From URL" event. Your zap should look like this so far: ![Urlbox choose event](/content/google-sheets-screenshots/urlbox-choose-event.png) Now click continue, and link your Urlbox account. You can do this by pasting in your Urlbox *Secret* key into the popup form: ![Urlbox auth](/content/google-sheets-screenshots/urlbox-auth.png) Click continue, now we arrive at the Urlbox screenshot options. Here we can choose the options for the screenshot, such as the url, size and format. For the URL, we want to select the URL from the Google Sheet, so click into the URL input, and in the dropdown, select the URL column from the Google Sheet. Zapier will show the URL of the row from the test trigger that we did earlier, to make it more obvious which data is being selected: ![urlbox setting the url in zapier](/content/google-sheets-screenshots/urlbox-setting-url.png) We can set a whole host of other options in this screen, but we will leave them all as the default for now. Scroll to the bottom of the urlbox options, click continue, then click 'Test action'. Zapier will now send the URL to Urlbox, and Urlbox will return a screenshot of the URL. If everything is working correctly, you should see the following from the test action: ![urlbox test action](/content/google-sheets-screenshots/urlbox-test-action.png) You can see that Urlbox has returned a `screenshotUrl` which is a link to the screenshot that was generated. We can use this `screenshotUrl` in later actions in the zap. -> Note: The `screenshotUrl` is a temporary URL and will expire after 30 days. In order to save the screenshot permanently, we need to save it to cloud storage. In this setup, we will use Google Drive, but you should be able to use any cloud storage solution such as Dropbox, or Amazon S3. ## Saving the screenshot to Google Drive Next, click the little '+' icon to add a new action to the zap. In the search box, type Google Drive, and select the Google Drive action, and then choose the "Upload File" event. ![upload file Google Drive](/content/google-sheets-screenshots/upload-file-google-drive.png) Click continue, and link your Google Drive account. In Google Drive, you should create a folder where you want the screenshots to be stored. For this example, I named the folder "Zapier Screenshots". If you want to link to these images from a website, it is necessary to make your folder public, so that the images can be accessed by anyone. To do this, right click on the folder, and choose "Share", and then under "General Access" select "Anyone with the link". Back in the zap setup, once you have linked your Google Drive account, click continue, and in the action panel, choose the drive, and appropriate folder. In the File dropdown, this is where we pass in the `screenshotUrl` from the Urlbox action. Click into the File input, and in the dropdown, select the `screenshotUrl` from the Urlbox action. ![select screenshot url](/content/google-sheets-screenshots/select-screenshot-url.png) For the File Name input, you can choose to use the URL from the Google Sheet action, so that each screenshot in Google Drive is named according to the URL. If you have other columns in your Google Sheet, such as the name of the website or product, you could also use this information to name the screenshot file. Now test the action, and all being well, the screenshot of the URL will appear in your Google Drive folder, and zapier will send back some information about the uploaded file: ![uploaded file](/content/google-sheets-screenshots/uploaded-file.png) ## Updating the Google Sheet with the screenshot URL Great, now the last step in the zap setup is to update the Google Sheet, with a link to the screenshot that we just uploaded to Google Drive. Back in your Google Sheet, create a new column and label it "Screenshot URL". This is where we will store the URL of the screenshot that we just uploaded to Google Drive. Back in the zap setup, add another action to the zap, and search for Google Sheets, and select the "Update Spreadsheet Row" event. Once again, go through the steps to link your Google account, and make sure to choose the same spreadsheet and worksheet as before. Now, the crucial part is the "Row" input. This is where we tell zapier which row in the Google Sheet to update. Click into the Row input, and in the dropdown, select the "Custom" tab, then expand the "1. New or Updated Spreadsheet Row in Google Sheets" dropdown, now select the "Row ID". ![select row id](/content/google-sheets-screenshots/select-row-id.png) -> Note: The Row ID is a unique identifier for each row in the Google Sheet. This is how zapier knows which row to update. In more complicated cases, you might want to use zapiers lookup row function to add a lookup step to the zap, where you can ensure the correct row is looked up and updated based on some matching condition. This allows you to perform something like a Vlookup. Now we should see more fields below corresponding to the column headings in the Google Sheet. For me this is "URL" and "Screenshot URL". We don't want to update the URL column, so leave that blank, but we do want to add the location of the screenshot into the Screenshot URL column, so lets update that field now. To do this, we need to use the following URL format, in order to get a direct link to the image in Google Drive: `https://drive.google.com/uc?id=DRIVE_FILE_ID`, so in the zapier dropdown, we first type: `https://drive.google.com/uc?id=`, and then we select the "ID" from the Google Drive action. It should look like this: ![update screenshot url](/content/google-sheets-screenshots/updating-screenshot-url.png) Click continue, and test action. If everything is working correctly, the Screenshot URL column of the corresponding row in your Google Sheet should update: ![updated screenshot url](/content/google-sheets-screenshots/screenshot-url-updated.png) So this has setup the zap for our single test row. Now we want to make sure that this zap runs for every row in the Google Sheet. ## Setting up the zap to run for every row in the Google Sheet Click Publish and give your zap a name. I named it "Screenshot a list of URLs in Google Sheets". Zapier will now publish your zap and turn it on, however nothing much will happen in your Google Sheet, because the zap will only trigger when either a NEW row is added to the sheet, OR a row is updated. However, it is possible to run the zap for the existing URL's in your sheet. To do this, we go to the 'zaps' item in zapier, find our zap, and click on the 3 dots to open the dropdown. Then we choose "Transfer Existing Data" in order to trigger the zap on our existing data in the Google Sheet. ![transfer existing data](/content/google-sheets-screenshots/transfer-existing-data.png) Now zapier will pull in all the rows from your Google Sheet. You can click "select all", to select all the rows to run the zap for. Then click next. ![select all rows](/content/google-sheets-screenshots/select-all-rows.png) Zapier will then show 'you're about to send x records from Google Sheets to Google Sheets' and you can click Send Data to run the zap. ![send data](/content/google-sheets-screenshots/send-data.png) ![success](/content/google-sheets-screenshots/success.png) After a short while, your Google Sheet will have updated and you should see the screenshot URL's in the Screenshot URL column. ![sheet updated](/content/google-sheets-screenshots/sheet-updated.png) Now, if you want to also show a preview of the screenshot, right inside your Google Sheet, you can create a new column and label it "Image", then use the following formula in the cell next to the screenshot URL: `=IMAGE("B2")` where B is the column name of your "Screenshot URL" column. Now copy the formula down the column, and you'll see a little preview of the screenshot: ![screenshot urls](/content/google-sheets-screenshots/screenshot-urls.png) ## Adding or updating a new URL to the Google Sheet Now that the zap is setup, you can add new URL's to the Google Sheet, and the zap will automatically run and capture a screenshot of the new URL, and update the Google Sheet with the screenshot URL. -> Note: Although the zap says it is 'instant', according to Zapier, the zap usually takes up to three minutes to run after your sheet has been updated, so if you don't see the screenshot URL in your sheet straight away, don't worry, it should appear after a few minutes. It usually works best when you append new rows to the bottom of the sheet, instead of inserting them in the middle of the sheet. If you're experiencing any problems getting your zap to run, [this helpful article](https://help.zapier.com/hc/en-us/articles/8496276985101-Work-with-Google-Sheets-in-Zaps#h_01HWQ0QNQYDDHCM07X3E2WHEDJ) from Zapier covers some common problems and how to overcome them, when working with Google Sheets. ## Conclusion In this guide, we showed you how to use zapier to loop through a list of URLs stored in Google Sheets, capture a screenshot of each URL, upload it to Google Drive, and then update the Google Sheet with the URL of the screenshot file in Google Drive. If you run into any issues with setting up zapier, please contact us using the chat widget on our website, and we'll be happy to help. --- # Render screenshots and HTML using chatGPT > With the Urlbox ChatGPT plugin, you can ask ChatGPT to generate screenshots and render any HTML you can dream of. Source: https://urlbox.com/chatgpt-render-screenshots-html Last updated: 2023-03-28 --- With the announcement of [ChatGPT plugins](https://openai.com/blog/chatgpt-plugins/), it's now possible to use chatGPT to interact with many external services and API's. Urlbox has created it's own chatGPT plugin which means it's possible to ask chatGPT to render any HTML or ask to 'see' a web page. It's also possible to generate PDF's from HTML or even scrolling videos of webpages. ![open graph image](/content/chatgpt-plugin/open-graph-image.png) ## Install the plugin At the time of writing, the plugin model is in Alpha and only certain OpenAI accounts will have access in order to test and install their plugins. To install the plugin, first ensure that you are using the plugin specific model of GPT: ![enable chatGPT plugin model](/content/chatgpt-plugin/select-plugin-model.png) Then, visit the plugin store from the chatGPT UI and click install unverified plugin: ![install unverified plugin](/content/chatgpt-plugin/install-unverified.png) Then, enter `urlbox.com` to install the plugin: ![install unverified plugin urlbox.com](/content/chatgpt-plugin/install-unverified-2.png) Click through the disclaimer and the next dialog will ask for your HTTP access token, this is where you will put in your Urlbox secret API key from any of your urlbox projects. ![insert secret urlbox api key](/content/chatgpt-plugin/add-secret-key.png) Great! Now you have the plugin installed and you can start using it. ## Using the plugin to generate a screenshot Let's take it for a quick spin. I simply asked chatGPT `what does apples homepage look like today?` and it correctly understood what I meant, and used the urlbox plugin to render a screenshot of apple.com: ![ask chaptgpt for apples homepage](/content/chatgpt-plugin/apples-homepage.png) Here are the options chatGPT sent to the Urlbox API: ![apple chatgpt urlbox options](/content/chatgpt-plugin/apple-urlbox-options.png) You can see it correctly passed in the correct URL and used quite sensible options for the width and height. ## Using the plugin to generate a PDF You can also ask chatGPT to render a PDF. Based on the previous context, I just prompted chatGPT like so: `how about in pdf format`, and the result: ![apple-pdf](/content/chatgpt-plugin/apple-pdf.png) ## Warning - Alpha software With the announcement of chatGPT plugins less than a week old at the time of writing, there are still of course some rough edges which i'm sure will be smoothed out over time. One example I encountered was that the model would sometimes add comments to the request JSON payload, causing a syntax error: ![chatgpt plugin syntax error](/content/chatgpt-plugin/syntax-error.png) You can just prompt chatGPT to never use comments in the request payload, and it will work more smoothly. ## See the latest news I asked to see the latest news, and it chose to render a screenshot of the CNN homepage: ![latest-news-screenshot](/content/chatgpt-plugin/latest-news.png) Unfortunately there is a large ad across the top of the screenshot, so I simply asked chatGPT `without the ads`: ![using-block-ads](/content/chatgpt-plugin/using-block-ads.png) and it correctly chose to set and send in the [`block_ads`](https://urlbox.com/docs/options.md#block_ads) option to Urlbox's API. ## Modifying the request The ad is blocked but there is still a huge space at the top of the page, obscuring most of the actual content. Simply asking for a taller screenshot, et voilà chatGPT correctly modifies the [`height`](https://urlbox.com/docs/options.md#height) option, keeping all other options the same as before: ![ask for a taller screenshot](/content/chatgpt-plugin/modify-screenshot-options.png) ## Rendering multiple screenshots You can get chatGPT to render multiple screenshots without even being that explicit, here I asked `can i see the webpages of the most popular saas applications`, then it asked for confirmation: ![ask for multiple screenshots](/content/chatgpt-plugin/multiple-screenshots.png) and it called the Urlbox API eight times to render the screenshots of saas application such as zoom, slack, salesforce etc: ![multiple screenshots response](/content/chatgpt-plugin/multiple-screenshots-response.png) ## Rendering HTML with the Urlbox chatGPT plugin One of the most powerful features of the Urlbox chatGPT plugin is that you can ask chatGPT to render any HTML you can think of, well, any HTML you can describe to chatGPT adequately enough :) Having asked for multiple screenshots of the most popular saas applications, I then asked chatGPT to render those screenshots as a grid in HTML: This was my prompt: `thanks, can you put them into a html gallery in a grid and then render the gallery` and chatGPT generated some HTML, passed it into the `html` option of the Urlbox API and returned the output: ![ask for html gallery](/content/chatgpt-plugin/ask-for-html-gallery.png) and it initially returned the screenshots on top of each other, which was not a bad attempt considering the prompt was not very explicit. I had imagined a classic gallery kind of grid structure, so I attempted to get chatGPT to improve the HTML by asking: `display the images smaller and make it a 3x3 grid` and it did just that: ![html grid](/content/chatgpt-plugin/html-grid.png) ## Using tailwind CSS Whilst that result was pretty cool, I then decided to go a little further and see how far I could push chatGPT to generate, and render HTML using Urlbox's API via the plugin. Here is my prompt: `amazing. now lets add a caption to each screenshot below it, and add some padding and margin between the screenshots. let's also add a drop shadow to each image. you can use tailwind for the css.` and the initial response resulted in a syntax error: ![initial error ](/content/chatgpt-plugin/initial-error.png) I figured that chatGPT was taking too long to generate the HTML string, and it was causing a syntax error because it was failing to finish generating the HTML in time, leaving an unclosed quotation mark: ![debugging html ](/content/chatgpt-plugin/debugging-html.png) By asking chatGPT to show me the HTML it was generating, I was able to see that it was indeed generating invalid/unfinished HTML. To ensure the HTML it generated was a little shorter, I just asked it to render 6 of the screenshots, (rather than the 8 it originally created): ![shortening html](/content/chatgpt-plugin/shortening-html.png) That seemed to do the trick, and the resulting output was: ![html with captions](/content/chatgpt-plugin/html-with-captions.png) ## Improving the styling Going a little bit further, I asked to `increase the padding, make the images have a softer rounded edge and put a subtle grey gradient on the background`. and here was the result: ![increase padding](/content/chatgpt-plugin/increase-padding.png) as you can see the result was pretty good, but the we can improve the output by asking chatGPT to render in a higher resolution and only render the body element. chatGPT correctly calls the urlbox API with the [`selector`](https://urlbox.com/docs/options.md#selector) option set to `body` and the [`retina`](https://urlbox.com/docs/options.md#retina) option set to `true`: ![asking for retina and selector](/content/chatgpt-plugin/asking-for-retina-and-selector.png) and the resulting output: ![grid high res](/content/chatgpt-plugin/grid-high-res.png) ## Adding a title and subtitle Finally, adding a title and subtitle, and we have a pretty cool screenshot gallery that could be used as the open graph image for this very blog post! ![final prompt](/content/chatgpt-plugin/final-prompt.png) and the result: ![open graph image](/content/chatgpt-plugin/open-graph-image.png) View the final generated image in full resolution [here](https://urlbox.com/content/chatgpt-plugin/open-graph-image.png.md) ## The possibilities are endless The possibilities are endless, and I'm sure you can come up with some pretty cool use cases for this plugin. Here's another gallery I generated after asking for screenshots of bootstrapped saas products, ![bootstrapped saas retina](/content/chatgpt-plugin/bootstrapped-saas-retina.png) chatGPT combined with plugins are going to be a pretty powerful combination when they become generally available. Using the Urlbox plugin, you can now extend chatGPT and get it to quickly generate screenshots of webpages, and iterate on and render HTML all using Urlbox's API. And with the recent release of [pix2struct](https://huggingface.co/google/pix2struct-screen2words-base), you'll soon be able to query and ask questions about a screenshot too... --- # Using AI To Classify Website Screenshots > Written in Python, using the deep learning libraries of Keras on top of Tensorflow. Source: https://urlbox.com/automated-screenshots/classify-website-screenshots-with-ai Last updated: 2022-03-07 --- ## Using AI To Classify Website Screenshots This article describes how the team at [Urlbox](https://urlbox.com/.md) built, trained and deployed a [convolutional neural network](https://en.wikipedia.org/wiki/Convolutional_neural_network) (CNN) model that can classify screenshots of websites with an accuracy of 98.75%. Written in Python, using the deep learning libraries of [Tensorflow](https://www.tensorflow.org/), given the URL of a website screenshot, it downloads the image, performs necessary preprocessing, and feeds this data to the model to classify the image. The result is a classification of the screenshot as either “successful” or “obscured”. The aim is to identify screenshots that have overlays, cookie banners, pop-ups, etc. that obscure the screenshot content and annoy [Urlbox](https://urlbox.com/.md) users. ![An Example of A Successful Website Screenshot](/content/classify-website-screenshots-with-ai/image5.png) *An example of a successful website screenshot* ![Example of an “obscured” website screenshot classified by the model](/content/classify-website-screenshots-with-ai/image4.png) *The same website, but obscured (and classified as “obscured” by the model).* ## Early Attempts - Multi-Class Classification Currently, we are only classifying screenshots as one of two categories: successful or obscured. However, early attempts included further categories, such as: broken and paywall. Training the model on screenshots in these four categories proved an accuracy rate of 92% on the training set, but only 50% accuracy on the (unseen) validation set of screenshots. Which is not a sufficient accuracy to have any useful application. However, removing the paywall screenshots from the training set (based on the assumption that paywall sites look relatively similar to successful sites), leaving the three categories of: successful, broken and obscured, resulted in 99% accuracy on training data and greater than 90% accuracy on (unseen) validation set of screenshots. While having greater than 90% accuracy may seem sufficient for practical applications, we felt that due to the small number of instances in the broken category, it was best to remove this category entirely until we could collect a large enough number of broken screenshot instances before incorporating them back into the model. Finally training the model on only successful and obscured screenshots resulted in an accuracy rate (on unseen data) of 98.75%. ## Creating A Dataset of Website Screenshots Despite there being some pre-existing [datasets of classified websites screenshots](https://www.kaggle.com/aydosphd/webscreenshots), there were none that were suitable for the task at hand. So the dataset had to be created from scratch and the images manually classified. Using a random sample of the websites from [The Alexa Top Sites List](https://www.alexa.com/topsites), we used the URLs of the top ten most recent Google search results of these sites to then generate screenshots of those sites via the [Urlbox](https://urlbox.com/.md) [API](https://urlbox.com/.md). These were then manually classified as either successful or obscured. While there are services that outsource the manual classification/labelling of images, such as AWS’s [GroundTruth service](https://aws.amazon.com/sagemaker/groundtruth/) in combination with AWS’s [Mechanical Turk](https://www.mturk.com/), to create large labelled datasets for deep learning projects such as this, getting set up with these services was deemed beyond the scope of this project. We wanted to build, train and deploy the model quickly without tying into a platform with which most of the team were unfamiliar. There are a few other ways to speed up the manual labelling step and deal with small (\< 1,000 instances) datasets, without compromising the speed of the model’s development with the model’s final accuracy. Firstly, simply scanning each downloaded screenshot and moving them to the correctly labelled directory, allowed over 100 screenshots for each category to be labelled within an hour or two. ![Example of Screenshot Manually Labelled As “Obscured”](/content/classify-website-screenshots-with-ai/image3.png) *Example of screenshot manually labelled as “obscured”* Secondly, training the model, even on this small dataset, gave it some power of classification. Not enough that we would want to use the model in a production environment, but enough to assist with classifying further unseen data, which we can use to then increase the size of the dataset used for training the model. We used the model trained on this small dataset to then classify unseen website screenshots. Clearly, there would be some misclassifications, but this step allowed us to rapidly classify a large number of screenshots using the partially trained model. These “first pass” classified screenshots were then rapidly scanned and any misclassified instances were removed or moved to the correct class/directory. The model was then completely re-trained afresh using this larger dataset... that the model itself helped to create. In addition to this, during training, we used a data augmentation step to create new, entirely synthetic versions of screenshots (using [Keras’ ImageDataGenerator](https://www.tensorflow.org/api_docs/python/tf/keras/preprocessing/image/ImageDataGenerator)) , based on the existing screenshots, to further increase the size of the dataset used for training. Ultimately, all to increase the accuracy of the model on unseen data. ## Choosing A Deep Learning Platform There are a number of “off the shelf” deep learning platforms that aim to facilitate the whole deep learning pipeline or make it easier for those without experience in this area to create deep learning models. When deciding which platform (if any) to use, one of the biggest factors in the decision should be: what platform/ ecosystem are the team currently using? We don’t want to burden the team with the extra cognitive load of having to learn a whole new ecosystem, just for a single application. While one of the team has used AWS’ [SageMaker](https://aws.amazon.com/sagemaker/) platform previously for training and hosting deep learning models, the rest of the Urlbox team are more familiar with the Google Cloud Platform (GCP) ecosystem of services. So this gave us an opportunity to experiment with GCP’s [VertexAI](https://cloud.google.com/vertex-ai) service. ## Google Cloud Platform’s Vertex AI This has a number of features that make training, deploying and hosting a deep learning model extremely easy. Using [VertexAI’s Image Classification Tutorial](https://cloud.google.com/vertex-ai/docs/tutorials/image-recognition-automl) as a starting point, you will notice some extremely useful features, that you can take advantage of even if you don’t use the whole service. For example, during the data import process, I was warned that there was an error and not all the data was imported. “Unable to import data due to errors… Warning: Annotation \`successful\` is deduped.” It automagically detects and removes duplicate images during the import process. This is an extremely useful feature that can help clean your data. Also, from the dashboard, you can quickly see exactly how many more instances you need of each class and it makes scanning the images (to make sure they are correctly labelled, etc) easier than on a local machine. ![GCP’s VertexAI Dashboard](/content/classify-website-screenshots-with-ai/image1.png) *GCP’s VertexAI Dashboard - Showing number of instances in each class.* After correctly organising the dataset as required, the model was trained on a few hundred instances of both classes in approximately 30 minutes and reached an accuracy of 85%. However, after an initial exploration, we choose not to commit to VertexAI. This was due to: 1. The comparatively higher cost for training and hosting the model. 2. The need to create an API wrapping the hosted model, before making a request. The VerexAI-hosted model endpoint isn’t a simple public endpoint as we had hoped. You still need to authenticate and then make a post request with the image as a base64 encoded string. Instead, we created our own containerised Flask API to wrap the trained model and host it as a serverless application on GCP’s [CloudRun](https://cloud.google.com/run) (their managed serverless offering) service. ## Training The Model The model was trained by reading each image, and its associated label (successful, obscured) was determined by the name of the directory the image was in (/dataset/successful, dataset/obscured, etc) and then each image was preprocessed (resized, etc) and added to an array. This array of images was then used to sample batches of images, which are fed to the model during the training process. The batch size, number of epochs and other hyperparameters can be tweaked to further improve accuracy, which I discuss later. The architecture of the network (ie: number of layers, number of nodes in each layer, activation type, drop out rate, etc) was chosen based on the known successful rule of thumb for this type of network. The code for this is below: ```python class BinaryCNN: @staticmethod def build(width, height, depth, classes): model = Sequential() inputShape = (height, width, depth) if K.image_data_format() == "channels\_first": inputShape = (depth, height, width) model = Sequential() model.add(Conv2D(32, (3, 3), input_shape=inputShape)) model.add(Conv2D(64, (3, 3), activation="relu")) model.add(MaxPooling2D(pool_size=(2, 2))) model.add(Dropout(0.25)) model.add(Conv2D(64, (3, 3), activation="relu")) model.add(MaxPooling2D(pool_size=(2, 2))) model.add(Dropout(0.25)) model.add(Conv2D(128, (3, 3), activation="relu")) model.add(MaxPooling2D(pool_size=(2, 2))) model.add(Dropout(0.25)) model.add(Flatten()) model.add(Dense(64, activation="relu")) model.add(Dropout(0.5)) model.add(Dense(1, activation="sigmoid")) return model ``` Moving from a multiclass classifier to a binary classifier required replacing the final, output layer of the network, which was a Softmax function (allowing multiclass classifications along with the associated probability of each classification) with a Sigmoid function (which is more suited to binary classification) (you can see this as the final layer in the above network architecture). Adjusting the size of the images up to 224 x 224 pixels (from an original 80 x 80 pixels), increased the accuracy to greater than 90%. Further pre-processing of the images, by cropping them to 1024 x 1280 (to only train and classify on the top fold of the page) (before resizing to 224 x 224), and cleaning the data to reduce ambiguity in each class, finally increased accuracy to 98.75% A sample of the training logs is shown below. Note the initial vs the final accuracy rate, of both the training data and the validation data (which is held back as unseen data to make sure the model is not overfitting on the seen, training data). We want to make sure that the accuracy rate and validation accuracy rate are similar. The validation accuracy rate tells us how accurate classifications will be on unseen data, which is what this application will be classifying in the real world. In this example, the model achieved an accuracy of 93.5% on the unseen data. ![Example of the Training Logs](/content/classify-website-screenshots-with-ai/image2.png) *Example of the Training Logs* We use the [EarlyStopping](https://www.tensorflow.org/api_docs/python/tf/keras/callbacks/EarlyStopping) and [ModelCheckpoint](https://keras.io/api/callbacks/model_checkpoint/) Keras callbacks to stop the training early and save the model once we have trained it to the highest accuracy on the validation (unseen) data. ## Data Version Control We use Data Version Control ([DVC](https://dvc.org/)) to manage our dataset. It's too big to host on Github, so we host it on AWS’s S3 and then use DVC to pull it down to our local machine, to use when training. This allows other developers to continue with the project, using the data the model was trained on as a basis for further work. DVC can also be used to control the versioning of trained models, labels, etc. ## Making a Classification Request The trained model is wrapped up in a simple Flask API, which on start up loads the model from disk, then per request: downloads the image from its URL, performs required preprocessing and feeds the image to the model to make a classification. A post request is made with a JSON body such as: ```json { "image_url": "https://some_example_screenshot_url.png" } ``` And the response is the simply the classification of the screenshot, either “successful” or “obscured”: ```json { "classification": "obscured", "probability": 0.08571445941925049 } ``` ## Further Work To Increase Accuracy & Speed of Classification We can use Keras’ autotuning of hyperparameters to randomly adjust the number of nodes, drop out rate, etc, of the inner layers of the network during training, finding the network hierarchy that results in the highest accuracy rate. To reduce complexity to a minimum, the model was trained locally on a CPU, then wrapped in a Flask API and deployed to GCP’s CloudRun. However it could be retrained, and deployed, on a GPU, which has been shown to significantly reduce both training and inference/classification time (possibly up to 10x improvement). This should mean we reduce the time to classify screenshots to significantly under 1 second per classification. --- # Here's How AI Can Help You Analyze Web Content > Here's how AI can help you analyze web content faster and more accurately than ever before. Source: https://urlbox.com/content-analysis-with-ai Last updated: 2023-07-19 --- AI has the potential to revolutionize the way we approach web content analysis as machine learning algorithms can sift through massive amounts of data at incredible speeds, identifying patterns, extracting insights, and even predicting future trends. In this article, we'll explore how AI can help you analyze web content faster and more accurately than ever before. We'll cover the different types of content analysis and the best way to feed data to the AI to cut costs. ## The need for automated content analysis Around [328.77 million terabytes](https://explodingtopics.com/blog/data-generated-per-day#how-much) of data are created each day, which is expected to increase by 25% annually. All this means is that the web is full of content, from blog posts and news articles to social media updates and user reviews. There's so much data out there that it's humanly impossible to analyze. Automating content analysis saves you time and resources and can help you find insights that might have been missed if you were doing it manually. For example, it can spot trends and patterns across thousands of articles or social media posts faster than a human ever could. But just automating the process isn't enough to get the most out of all that web content. To really unlock the value in the data, you need to go deeper and be more accurate in your analysis. That's where AI comes in. It doesn't just automate content analysis but uses sophisticated algorithms to understand the context and pick up on subtleties. ## Understanding AI and its role in content analysis AI has been around for some time, with the first instances able to do simple tasks like recognizing patterns. The latest AI algorithms, like [ChatGPT](https://urlbox.com/chatgpt-render-screenshots-html.md), can now achieve way more complicated things, like understanding natural language or making advanced predictions based on data. But AI's capabilities extend beyond understanding and making predictions. It's a powerful tool for content analysis, capable of sifting through vast amounts of web content to classify web pages, understand sentiment, or extract keywords. And to achieve the best results, you need to feed it the right data. This leads us to one of the most important aspects of AI content analysis: data preparation. ## How to input data for AI analysis Before AI can analyze web content, you must collect and prepare the correct data. This means pulling out the relevant content from the web and formatting it in a way that's easy for the AI to analyze. Different tools out there can help with this, and one of them is [URL2Text](https://url2text.com/). URL2Text takes the text content from a given URL and turns the HTML code of the webpage into markdown, but it can also [extract metadata](https://urlbox.com/metadata.md) for advanced analysis. Markdown is a lightweight markup language with plain text formatting syntax. Its simplicity lies in its easy-to-read and easy-to-write syntax. It allows you to format text using simple punctuation and characters, which makes it quicker and more straightforward than other markup languages like HTML. And because markdown formatted text features fewer characters than HTML, it can also greatly enhance the efficiency of AI analysis, as the algorithm will use fewer tokens for each body of text. This efficiency really matters when you're analyzing a lot of data, like tens or hundreds of web pages. The fewer tokens you use, the less computing power you need, which can save a lot of money. Plus, with fewer tokens, AI models can process more data within their maximum token limit, allowing you to analyze more content in one go. ## Types of web content analysis that can be automated with AI Now that we've covered how to prepare and input data for analysis let's talk about what AI can do with that data. ## Sentiment analysis with AI First up, let's talk about sentiment analysis. This is all about figuring out the emotions behind a piece of text. It's an excellent technique for businesses that want to know what their customers think about them or for anyone who wants to track public opinion or predict trends. AI doesn't just do the same thing as manual sentiment analysis, only faster. It actually does it better. Traditional sentiment analysis can get tripped up by sarcasm, ambiguity, or sentiment that depends on context. AI can handle these complexities, making sentiment analysis more accurate and detailed. For instance, say a business wants to know how customers feel about their new product. They could use AI to analyze customer reviews, social media posts, and other online content. The AI could quickly figure out the overall sentiment and spot any specific issues or praises that come up a lot. This could give the business valuable insights that they could use to improve their product or their marketing. ## Topic identification with AI Topic identification is all about figuring out the main themes or topics in a piece of content. It's handy for understanding what's being talked about in a large dataset, like news articles, blog posts, or social media updates. Just like sentiment analysis, AI can take over the task of topic identification. It can go through a lot of text quickly, spotting patterns and themes. It groups similar content together, so you can see what topics are being talked about the most. AI can also understand the context and the meaning behind the words. So, for example, it might identify "climate change" as a topic, even if some texts talk about "global warming", others about "rising temperatures", and others about "carbon emissions". This ability to understand the meaning, not just the words, makes AI a powerful tool for topic identification. For example, let's say a researcher wants to know the main topics being discussed in a large collection of online forum posts. They could use AI to quickly figure out the most talked-about topics and how they relate to each other. This could give the researcher valuable insights and save them a lot of time. ## Text classification with AI AI can automatically sort web pages into different groups or categories. It's a valuable technique for managing and organizing many web pages based on their content and can even be used to [classify website screenshots with AI](https://urlbox.com/automated-screenshots/classify-website-screenshots-with-ai.md). Think about a news website that publishes hundreds of articles every day. Sorting each article into the correct section (like "Sports", "Politics", "Technology", etc.) would take a lot of time if done manually. But AI can do this automatically based on the content of the articles, saving a lot of time and making sure the classification is consistent. E-commerce websites can also use text classification to sort products into categories based on product descriptions. This makes it easier for customers to navigate the site and find what they're looking for. Moreover, text classification can also detect spam in comments or reviews. Spam is a problem for many websites, and filtering out spam comments manually can be daunting. AI models can be trained to recognize spam comments and filter them out automatically, thus helping businesses keep the discussion on the site high quality. ## Keyword extraction with AI Keyword extraction involves identifying and pulling out the most relevant keywords from a piece of text. One of the primary uses of keyword extraction is to improve search engine rankings. By identifying the most relevant keywords in your web content, you can optimize your content to increase your chances of ranking higher on SERPs. This is a vital part of Search Engine Optimization (SEO), which is all about making your web content more visible to people looking for information about your offer. Another use of keyword extraction is to spy on competitors. You can analyze their web pages and extract the keywords they are targeting. This can help you identify gaps in your strategy and find new keyword opportunities that would otherwise slip by. Keyword extraction can also be used to create advanced search functionalities on websites. By identifying and indexing the main keywords in each piece of content, you can create a more sophisticated search feature that allows users to find the most relevant content for their search queries. This can significantly improve the user experience on your site, making it easier for users to find the information they're looking for. Finally, keyword extraction can be used to create tags for web pages. Tags are a great way to categorize and organize content on your site, making it easier for users to find related content. By automatically extracting the most relevant keywords from each page, AI can help you create accurate and relevant tags for each piece of content. ## AI is revolutionizing web content analysis AI has the potential to revolutionize the way we analyze web content. From automating the actual process to enhancing the depth and accuracy of insights, AI helps businesses better understand their audience and potential customers. The key to harnessing the power of AI lies in understanding its capabilities and knowing how to apply them effectively. As we've discussed, techniques like sentiment analysis, topic identification, text classification, and keyword extraction can provide valuable insights into your web content. But to get the most out of these techniques, you must prepare your data correctly and choose the right tools for the job. One such tool is [URL2Text](https://url2text.com/), which can convert webpages into markdown, an ideal format for AI processing. By reducing the number of tokens used in the analysis, tools like this can make the process more efficient and cost-effective, especially when dealing with large volumes of data. In conclusion, AI offers a powerful solution for web content analysis, capable of transforming how we understand and interact with the web. As the field of AI continues to evolve, we can expect to see even more innovative applications of this technology in the realm of content analysis. So, whether you're a business owner, a researcher, or just someone interested in understanding the web better, it's worth exploring what AI can do for you. --- # Convert a Webpage to PDF Using APIs - The Complete Guide > Looking for a reliable way to convert webpages to PDFs? This guide includes everything you need to know, from building your own microservice to using APIs. Source: https://urlbox.com/automated-screenshots/convert-webpage-to-pdf Last updated: 2025-03-21 --- If you're looking for a reliable and fast way to convert webpages to PDFs, then you've come to the right place. In this article, we'll cover: - Why converting webpages to PDFs can benefit your business workflow - The most efficient tools and APIs for bulk PDF conversion - Step-by-step guides for converting webpages to PDFs in popular browsers - A detailed comparison of the best webpage-to-PDF converter APIs for different needs ![](/content/convert-a-webpage-to-pdf-using-apis/image2.png) ## Converting a Webpage to PDF Use Cases People are always looking for ways to share, print, and view content in various formats, such as PDF files. This article highlights some of the best ways and tools you can use to convert a webpage to PDF automatically. Many people recognize the value of a PDF file. It's a versatile format that can be viewed, printed, and shared from a variety of devices, including computers and mobile phones. PDF files make it easy to share content that has been created or published online. For example, if you have a blog or website where you post articles, you might want to be able to convert the articles into a PDF file that your readers can download (otherwise known as a lead magnet). This way, you can use an existing piece of content to increase your email list. In other situations, PDFs may be used for internal purposes to distribute documents within an organization. Other use cases include: - Generating PDF invoices from HTML - Generating PDF catalogs of influencer or PR campaigns - Submit PDFs of webpages for compliance reviews - Generate PDFs on demand. There are many different ways to convert a webpage to a PDF document programmatically. These techniques take different approaches and require varying levels of programming expertise. While the concept of creating a PDF from HTML is simple, the details involved are often confusing for web developers and business owners alike. To make matters worse, solutions to this problem are constantly changing as browsers evolve. Read on to learn some of the available options for converting an HTML page to PDF, from DIY examples to APIs that can be used with a single line of code. ## How to Convert Webpage to PDF in Various Web Browsers Before exploring API solutions, let's look at the built-in options in popular browsers: ### Chrome 1. Open the webpage you want to convert 2. Press Ctrl+P (Windows/Linux) or Cmd+P (Mac) 3. Change the destination to "Save as PDF" 4. Click "Save" ### Firefox 1. Open the webpage 2. Click the menu button (≡) and select "Print" 3. Choose "Print to File" and select PDF as the output format 4. Click "Print" ### Safari 1. Open the webpage 2. Click on "File" > "Export as PDF" 3. Choose a location to save the file 4. Click "Save" While these methods are convenient for occasional use, they lack automation capabilities and consistent formatting that APIs provide. ## A PDF has to look professional Try manually printing a webpage with the built-in Chrome functionality, and you’ll quickly realize that generating a PDF from a webpage is more complicated than it seems. Of course, you can implement your microservice or even use a headless browser to generate that PDF, but that doesn’t really solve the problem. Think of all the extra elements that’ll be part of the file, like the ads on your website, the cookie banners, privacy disclaimers, and the list goes on and on. If you're trying to generate screenshots at scale, you want to make sure your go-to webpage to PDF tool can handle these problems by default. There are some great screenshot tools, but just a handful would let you easily create high-quality PDF files. Even if you can convert your site into a PDF, when you look at the final result, there is still plenty of work to do before sharing these files with anyone. Here are some things that you have to pay attention to in case you want to go the DIY way: - The quality of the screenshots themselves - Ads, cookies banners, and other obscuring elements - That your site looks the same in any browser - you want users to have the experience exactly as they see it in their browser - Constant updates are required because browsers are constantly updating and may often break compatibility with existing services - Font rendering is critical - if you choose to embed fonts and have them appropriately rendered in your PDFs, then they need to look good in every browser as well - Running out of memory because too many PDFs are being processed at the same time. ## Building your own webpage to PDF microservice Chances are you read this article because you've realized creating PDFs from webpages is a more challenging task than initially expected. You’ve gone through Stackoverflow and already asked your friends, but you haven’t entirely found your answer yet. Some people are leaning towards [Puppeteer](https://urlbox.com/website-screenshots-puppeteer.md), which is Google's library for creating PDF files from HTML content. Others are suggesting Playwright, a popular library that does essentially the same thing as Puppeteer but has a much gentler learning curve. As it turns out, many business owners have built their own webpage-to-PDF microservice in-house because they don't need to generate thousands of PDFs at once. These small businesses usually have a handful of PDFs they need to generate per month, so they can build this functionality themselves and save money on third-party services. So which one should you use? Well, to make an educated decision, let's take a look at how Puppeteer and Playwright compare to each other: ### Puppeteer Puppeteer is by far one of the most popular libraries for PDF generation. It's an easy-to-use open-source library, plus you can find examples of how to work with it just about anywhere. The downside is that it requires an out-of-process server. Puppeteer does all its PDF generation asynchronously, sending the generated PDF back to your application upon completion. This makes Puppeteer less than ideal for applications that need to generate PDFs as part of their core functionality. Puppeteer isn't a great choice if you want more than just PDFs—it's best when you're using it only as a bonus feature on top of your core functionality, like an eCommerce site that generates invoices or receipts automatically. ### Playwright With Playwright, you can generate PDFs from any website, whether the single page of a manual or a multi-page document. It helps you extract text from PDFs by typing a few lines of code. You will be able to save yourself hours of work and have a lot more fun by using this tool to automate your processing of PDFs. While using Playwright, you also have many options in terms of tweaking the PDFs, such as changing the orientation, width, height, or format. However, as mentioned before, running your own microservice becomes a chore once you scale. The biggest impediment is running into bugs and the microservice getting extremely expensive. The solution is often outsourcing your website to PDF service to an API. ## Webpage to PDF APIs Screenshots are a standard tool in software development and testing, and as such, there is a growing number of companies offering screenshot or webpage to PDF APIs. These are much like the APIs you use to access other web services, such as Twitter or Facebook, but instead of providing data on a website's content, they provide a pixel-perfect image or PDF of the page. Finding a [screenshot API](https://urlbox.com/screenshot-api.md) is a lot like shopping for a hosting provider. The important thing to look for is not just the features included with the service but whether or not those features are exposed via a robust API. With that in mind, it's essential to choose an API provider who will be able to evolve and grow with your needs. ### Urlbox ![](/content/convert-a-webpage-to-pdf-using-apis/image1.png) Urlbox is a simple and reliable API that can convert any webpage into a pdf on demand. Urlbox offers excellent support for converting web pages into PDFs, with a large variety of options such as: - set the PDF page size, width, height, and margin - print background images in the PDF or not - control how Urlbox caches your PDFs - configure the browser before navigating the URL - set cookies on request when loading a URL. ### Other webpage to PDF APIs 1.[Api2Pdf](https://rapidapi.com/api2pdf/api/api2pdf/) Api2Pdf is an API that allows you to generate and merge PDFs from HTML, URLs, images, or office documents. It was updated a year ago, and you can use it with Node.js, Go, Kotlin, and various other programming languages you might be using in your stack. 2.[cloudlayer.io](https://rapidapi.com/cloudlayerio-cloudlayerio-default/api/cloudlayer-io/) With cloudlayer.io, you can generate PDFs by making a GET request to convert URLs to images or PDFs. The API was updated over eight months ago. 3.[Pdflayer](https://rapidapi.com/apilayer/api/pdflayer/) Pdflayer is a lesser-known API that converts HTML files (and URLs) to PDF files. It comes with a series of layout adjustment options, authentication and security, design and branding tweaks, and other functionalities. ## Use a reliable and fast webpage to PDF API Urlbox is a service designed to make it easier for people to take screenshots or PDFs of webpages and use the assets without worrying about scaling, hosting, or dealing with the edge cases that come with generating PDFs of various websites. We handle the scaling, the hosting of the screenshot images and PDFs, and we solve a lot of the edge cases that people will run into, such as blocking ads and cookie banners automatically. Try it out for yourself [here](https://urlbox.com/pricing.md)! ## Conclusion Converting webpages to PDFs doesn't have to be complicated or resource-intensive.

Source: https://urlbox.com/automated-screenshots/convert-html-to-svg Last updated: 2022-10-31 --- An SVG (Scalable Vector Graphics) is a unique format that uses "vector" data instead of pixels to generate an image. Because of this, SVGs files can be scaled with virtually no loss in quality. SVG files are nothing more than pure XML. This means they can be edited with any text editor, but what really makes this format shine is the ability to animate its elements and attributes. Moreover, they are smaller and sharper than PNGs, which speeds up page loading time (especially on Retina displays). All these properties make the SVG file format ideal for logos, icons, or other simple graphic images. In this article, I'll share 3 of the best tools you can use to convert HTML to SVG at scale and how they work. ## Urlbox - Best HTML to SVG generator API Urlbox is a screenshot service API that can convert URLs or HTML files to SVGs, but it also works the other way around. Working with all major programming languages, Urlbox is the best option if you are looking for a quick and reliable way to generate SVG files at scale. ## How does Urlbox work There are multiple ways to convert an HTML file to SVG with Urlbox: - by using the Sandbox mode - by using [no-code tools](https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier.md) e.g. Zapier - by using a RESTful API request URL - by generating links straight from your app Regardless of your chosen method, you'll need to sign up for a [7-day free trial](https://urlbox.com/pricing.md). ### Converting an HTML file to SVG in the Urlbox Sandbox After you have created your account, you will be automatically redirected to the Urlbox dashboard. Click on the [Sandbox](https://urlbox.com/dashboard/sandbox.md) link in the menu on the right. Urlbox lets you convert any URL or HTML file to SVG, but it can also generate images in other formats (PNG, JPEG, WEBP, AVIF, and even PDF). Now, all you have to do to convert your HTML into an SVG file is to: - Click on the "HTML" button at the top of the page and paste in your HTML code - Select SVG under the output format - change the final image width and height and click "Render." That's it; your HTML has been converted to an SVG file. ![image3](/content/convert-html-to-svg/image3.png) Going one step further, you can add an ID to the element you want to convert and instruct Urlbox to render that specific element from the Render Mode. Of course, this method requires you to convert the HTML code to an SVG file manually, but it's a great way to understand how Urlbox works and get an overview of all its functionalities. ### Convert HTML to SVG at scale using no-code tools (with Urlbox and Zapier) Urlbox's Zapier connector can convert multiple HTML files to SVG without writing a single line of code. Note: for this method to work, you must have a paid Zapier account for $29.99 monthly. I have covered in a previous article the exact step-by-step process you can follow to integrate Urlbox with Zapier to generate images from a list of links (you can check it [here](https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier.md)). This method works best if your HTML can be accessed via a URL before you convert it to SVG. If not, you will need to code your own custom solution. ### Convert HTML to SVG at scale by using a RESTful API request URL Previously, I described using Urlbox's Sandbox to generate SVG files from HTML manually. But the Sandbox does more than rendering; it gives you a Request URL you can use inside your application. ![image2](/content/convert-html-to-svg/image2.png) You can alter the parameters to reflect your HTML, but make sure to encode the URL. When you visit the URL, Urlbox provides the requested screenshot as an inline image that'll render within the `<img>` tag. You can save the image to a file by requesting the URL via an HTTP library. Here's a step-by-step guide on how to [convert HTML to SVG with Urlbox in PHP](https://urlbox.com/website-screenshots-php.md#taking-a-screenshot-with-urlbox). ### Convert HTML to SVG at scale within your own application Another way to convert HTML to SVG is to create your own HTML to SVG file converter using Urlbox's API and your preferred programming language. As mentioned before, Urlbox works with all major programming languages: - [Node.js](https://urlbox.com/7-ways-website-screenshots-nodejs-javascript.md) - [Ruby on Rails](https://urlbox.com/website-screenshots-rails.md) - [Python](https://urlbox.com/website-screenshots-python.md) - [Java](https://urlbox.com/website-screenshots-java.md) - [C#](https://urlbox.com/website-screenshots-c-sharp.md) - [Elixir](https://urlbox.com/how-to-take-website-screenshots-elixir.md) - [Golang](https://urlbox.com/golang-website-screenshots.md) - [Rust](https://urlbox.com/website-screenshots-rust.md). Urlbox makes the whole HTML to SVG conversion process a breeze regardless of how many files you have to convert at once. ## Convertio - Online HTML to SVG file converter Convertio is an online service that can convert between 300 different file formats. ![image1](/content/convert-html-to-svg/image1.png) You can convert HTML to SVG by uploading your file from your local machine or your cloud storage accounts (works with Google Drive and Dropbox). Using their website, you can manually upload your documents one by one and select the output file format from the drop-down list (in this case, it will be SVG). The conversion can take 1 to 2 minutes for each file you upload. This can be a significant drawback if you have many files that need to be converted or are building an application. To better put this into perspective, Urlbox takes just a few seconds to generate an SVG from an HTML file. ### Convertio API and Pricing Convertio does provide an API you can use to integrate it with your application. When this article was written, Convertio had developed an official PHP wrapper with Node.js and Python support on the way. Convertio's API works with prepaid packages revolving around conversion minutes. The cheapest plan is $13 and comes with 1000 conversion minutes (1.3 cents per minute). Opting for this plan will allow you to convert between 500 and 1000 files, after which you will need to purchase more conversion minutes. Of course, the more minutes you buy at a time, the cheaper they are. For example, if you are to purchase 10,000 minutes, you have to pay 0.86 cents per minute (33% cheaper than the smallest plan). ### ConvertAPI - Versatile File Conversion API ConvertAPI is a comprehensive file conversion REST API service providing conversions for more than 200+ file formats. ![image4](/content/convert-html-to-svg/image4.png) It can connect to Zapier for no-code implementations, or you can follow their documentation to implement it within your application. They currently have code examples for some of the most popular programming languages: - DotNet - Java - Python - Ruby - PHP - Go - Node.js. It's important to mention that it can not directly convert HTML to SVG. Instead, you'll need to convert your HTML to a different image format (like JPEG or PNG) and convert that image to SVG. Of course, this is not ideal as the final image quality may be compromised, not to mention you'll have to pay for two conversions instead of one. And with pricing plans starting at $30 per month for 1000 conversions, ConvertAPI might not be the best tool to use if you're simply looking for an HTML to SVG converter. ## Conclusion - Best HTML to SVG file converter The best way to convert HTML to SVG at scale is by using [Urlbox](https://urlbox.com/pricing.md). It's cheaper and faster than the other services, works with all major programming languages, and can integrate with thousands of other apps via the Zapier connector. But if you are looking for a solution to convert between other file types (not just images), then you should go with either Convertio or ConvertAPI. ## FAQ ### Is SVG based on HTML? No, SVG is XML based. The `<svg>` HTML element is a container for SVG graphics and can seamlessly integrate into your code. You can even attach JavaScript event handlers for an `<svg>` element. ### Is SVG better than PNG? SVG is better than PNG in specific scenarios. Compared to PNG files, SVGs can be animated using Javascript. This makes it an excellent format for interactive websites, mainly because the browser can automatically re-render the shape if the attributes of an SVG object are changed. ### How to convert HTML to SVG? The best way to convert HTML to SVG is by using a converter. Since SVG is XML based, you can also manually code the file, but this can take a long time and is not scalable. ### Can I export part of an HTML page to an SVG image? Yes, you can export a part of an HTML page or a single element to an SVG image. The fastest way to do so is by using [Urlbox](https://urlbox.com/pricing.md). --- # Convert Links To PDF At Scale - Best Screenshot APIs and Tools > Converting a webpage to PDF can be daunting, especially if you want a high-quality document. Learn how to convert links to PDFs at scale using screenshot APIs and tools. Source: https://urlbox.com/automated-screenshots/convert-links-to-pdf Last updated: 2025-03-21 --- Converting a [webpage to PDF](https://urlbox.com/automated-screenshots/convert-webpage-to-pdf.md) can be a daunting task, especially if you are looking to get a high-quality document.

But Urlbox does more than screenshots; it helps you configure how the document will look before you generate it. ### Urlbox Features and Pricing If you've ever tried capturing a [full-page screenshot](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md), you probably know how most tools struggle to render sticky elements (like menus, chat bubbles, etc.). Not to mention the pesky cookie banners and ads popping on screen. With Urlbox, you can automatically hide any elements from the target web page (before it's converted into PDF), [plus more](https://urlbox.com/features.md): - set up custom cookies - configure the geolocation - specify a custom user agent - wait for the page to fully load before converting it to PDF. Once you're satisfied with how the page will render, you can move on to configure the look of the actual PDF document, things like: - page size (from A0 to A6 plus more) - margins and orientation - the scale, DPI and CSS Media. The best part is that you can try Urlbox for [free for seven days](https://urlbox.com/pricing.md). After creating an account, you can navigate to Sandbox mode, where you'll find all previously mentioned options. Depending on how many links you have to convert to PDFs, you can pick from one of the four [available plans](https://urlbox.com/pricing.md), with the cheapest one starting at just $19/month and going all the way to $3,500/month. ## Api2pdf - Cheapest URL to PDF API This service stands out from the crowd by taking a different pricing approach than the others. Instead of paying for the number of documents you generate each month, you can either: - pay a $1/month fee plus $.001 per Mb bandwidth and $0.00019551 per second of computation - pay a $99 setup fee (for managed hosting) plus a minimum of $200/month in server fees - pay a one-time $12,000 fee and use your servers to host it. That's a complicated pricing plan, so you have to do some math to see which option makes the most sense for your specific use case. Api2pdf lacks built-in rendering features, meaning you will have to write and debug more code to be able to edit the page you're capturing. If speed and quality are of higher priority than price, you might want to try another service from this list. ## PDFmyURL - Advanced URL to PDF API This API packs some powerful features compared to the others, mainly regarding PDF security options. With PDFmyURL, you can automatically set up user and owner passwords to the document to keep unauthorized people from accessing your PDFs. At the same time, you can disallow printing, content copying, and annotation from the respective PDFs. Moreover, with this API you can: - change the PDF page size, margins, and orientation - add custom Headers, Footers, and CSS - add a watermark to your PDFs. Their pricing plans start at $19/month, which allows you to generate up to 500 PDFs per month. The next plan goes for $39/month, for which you can generate up to 2k PDFs per month and enjoy Priority Email Support. This is an excellent service if you need extra security options for your PDFs, but it has a drawback compared to Urlbox. You can only display a "save as PDF" link on web pages of up to 3 different domains, which is a deal breaker for certain developers. ## PDFSwitch - Ligthweight URL to PDF API Last but not least in this list is PDFSwitch, a lightweight URL to PDF API. It doesn't come close to the others when it comes to features, but it can get the job done. This API allows you to set up basic pre-render settings like: - custom CSS and Javascript - custom Headers and Footers - delay the render after the page is loaded or wait until a DOM element matching the provided CSS selector becomes present on the page. When it comes to PDF options, you can: - configure the document's format - change the orientation and margins - set up the maximum number of pages your document should have. If that functionality is what you are looking for, this API is a great option, especially since they offer a free plan that allows you to run 50 conversions per month. Their paid plans start at $9/month, letting you convert up to 1000 URLs or HTML documents to PDF each month. ## What's the best URL to PDF converter? As with everything else, it all depends on your specific needs. Each service has its pros and cons, as described earlier. If you are looking for the cheapest option available to convert links to PDF at scale, then API2Pdf might be just the thing. On the other hand, if you want to secure your PDFs with passwords or automatically add watermarks to them, you should pick PDFmyURL. However, one thing is certain. With many different page rendering options and the ability to edit your PDF document settings, Urlbox is the most robust service on this list. If you are still unsure which service to pick, you can try Urlbox for [free for seven days](https://urlbox.com/pricing.md) (no credit card required). ## Links to PDF FAQ ### Can you save a link as a PDF with Urlbox?

In this article, I will show you how to automatically generate and store daily screenshots of any website. I'll also share some tips and tricks you can follow to create pixel-perfect screenshots ready to be archived. ## Why generate and store daily screenshots? Generating and storing daily screenshots of your website and social media accounts can provide several benefits, especially if you're looking for ways to improve your online presence and stay ahead of the competition. By saving regular snapshots of your website, you can maintain a historical record of its development and changes over time, which virtually means you will create your own [web archive](https://urlbox.com/website-archive-tools.md). This can be useful for legal or reference purposes and for tracking your website's progress and evolution. For businesses that operate in regulated industries, such as finance or healthcare, keeping track of social media posts is essential for compliance reasons. By creating a [social media archive](https://urlbox.com/social-media-archive-tools.md), you maintain a record of all your online activity and ensure that you're following regulatory guidelines. In addition, keeping track of what people say about your brand helps you identify areas where you need to improve your products or services and track customer satisfaction over time. But you can also generate daily screenshots of your competitors' websites to keep track of their products, services, and marketing strategies. This helps you identify improvement opportunities in your business operations and stay ahead of the competition. Regardless of your end goal, you'll find that the best way to capture daily screenshots is by automating the process. This will save you countless hours and ensure the final image is accurate and high-quality. ## Best practices for generating and storing daily screenshots Generating and storing daily screenshots of your website and social media accounts is an effective way to maintain a historical record of your online activity.

Automate the process as much as possible - various tools can help you automate this task, such as [website monitoring software](https://urlbox.com/website-monitoring-tools.md) and [social media archiving tools](https://urlbox.com/social-media-archive-tools.md). By automating the process, you can focus on other important aspects of your business. 2. Regularly review the screenshots for any issues - while automation can make the process more efficient, it's important to review the screenshots regularly to ensure they are accurate and complete. Make sure to check for any issues or errors, such as missing screenshots or distorted images. Regular review can help you catch any issues early and avoid potential problems in the future. 3. Keep the storage organized and easy to access - as you accumulate more screenshots over time, it's important to keep the storage organized and easy to access. Make sure to label each screenshot clearly and store them in a logical, easy-to-navigate folder structure. This can save you time when you need to locate specific screenshots later. 4. Be mindful of the storage costs - storing daily screenshots can take up a significant amount of storage space, depending on the screenshots' number, size, and file format. Make sure to choose a storage option that meets your needs and budget. Various storage options are available, such as cloud storage, external hard drives, or network-attached storage (NAS) devices. Each option has its own advantages and limitations. ## How to generate daily screenshots There are a variety of tools that allow you to capture screenshots automatically at specific time intervals, each of them with its unique advantages and disadvantages. They can be broken down into three main categories: 1.

Source: https://urlbox.com/data-archiving-strategies Last updated: 2025-03-21 --- In today's data-driven world, businesses generate vast amounts of data, but most do not have a data archiving strategy. Data archiving ensures that critical data is preserved long-term, even as technology and storage mediums change. This approach can protect your business against data loss and ensures that critical information is available when needed, especially in case of a surprise inspection or audit. An effective data archiving strategy can help you reduce costs, accelerate digital transformation and ensure you have access to all your data whenever you need it. In this article, we will explore what data archiving is, why it's important, and the best practices and benefits associated with implementing a data archiving solution. ## What is data archiving? ![graphic illustrating various data archiving strategies and tools](/content/data-archiving-strategies/image1.png) Data archiving is the process of systematically moving infrequently accessed data to a separate storage location for long-term retention. This involves identifying data that is no longer needed for daily operations but must be preserved for legal, regulatory, or business reasons. The archived data is stored securely and cost-effectively for a defined period of time. Data archiving can apply to various types of data, including emails, documents, images, videos, and more. In recent years, with the increasing use of online platforms and social media, [archiving web pages](https://urlbox.com/website-archive-tools.md), [social media posts](https://urlbox.com/social-media-archive-tools.md), comments, and mentions have become increasingly important. This data is often subject to legal and regulatory requirements and can be critical to protecting your brand's reputation. ## Why data archiving is important Data archiving is an important aspect of data management that can help businesses ensure compliance, reduce storage costs, preserve valuable data, and protect against legal and reputational risks. It can also help you [mitigate the risks of cyber attacks](https://urlbox.com/urlscan-alternatives.md) or malicious actors, as you will be able to access most of your lost data. ## How to implement a data archiving strategy The process of archiving data used to be complex and quite expensive, especially if your business generated vast amounts of data, but this changed in recent years. Cloud storage solutions have become increasingly accessible and data archiving tools are popping up one after another, plus, they are easier than ever to implement. All this means it's the perfect time to start implementing a data archiving strategy for your business. Here are the steps you should follow to create a simple yet effective data strategy. ### 1. Identify and prioritize your data Take your time to identify and prioritize the data that needs to be archived based on how frequently it's accessed, any regulatory requirements, and its overall importance to your business. You should keep archives of your customers, inventory, web pages, social media posts, and mentions. ### 2. Define retention periods Determine how long each type of data should be retained based on legal and regulatory requirements as well as your business needs. This will ensure that you are retaining data for the appropriate length of time and not exposing yourself to legal or operational risks. ### 3. Choose an archival storage solution You should explore different archival storage solutions, such as cloud or hybrid options. Consider factors like cost, performance, and scalability to choose the solution that best fits your business. For example, you can host your archives on Amazon S3, Google Drive, or a data warehouse. ### 4. Automate the archiving process Consider automating the archiving process using software tools and automated workflows. This will help you save time and reduce the risk of human error, plus it will greatly reduce your overall costs. ### 5. Test and verify your archives Regularly test and verify your archives to ensure that the data is retrievable and has not been corrupted or lost. This will help you catch any potential problems early and minimize the risk of data loss. ### 6. Integrate archiving with backup and disaster recovery Make sure your archiving strategy is integrated with your backup and disaster recovery plans. This will help you protect your archived data in the event of a disaster or system failure. It's best to store your data in at least two different environments. ### 7. Leverage data archiving tools Use specialized [data archiving tools](https://urlbox.com/data-archiving-tools.md) like URLbox to archive web pages, social media posts, and other types of digital content. These tools can help simplify and automate the archiving process, making it easier for you to archive data and reduce the risk of compliance violations. By following all these steps, you can ensure your business complies with legal and regulatory requirements, reduces costs, preserves valuable data, and protects against legal and reputational risks. ## Benefits of Data Archiving The right data archiving strategy provides several advantages that can significantly impact your business operations. Above everything else, archiving your social media activity can help you protect against legal and reputational risks. It allows you to quickly identify any potential compliance violations or negative feedback and take appropriate action to prevent negative consequences for your business. In addition, it can also help you gain valuable customer insights. Social media is a valuable source of customer feedback, and by archiving social media posts and mentions, you can better understand customer needs and preferences. You can use this information to improve your products and services, enhance customer experiences, and ultimately drive revenue growth. Furthermore, archiving your web pages and social media content provides a historical record of your digital presence. This can be useful for future reference and analysis, helping you better understand how your [online reputation](https://urlbox.com/online-reputation-monitoring.md) has evolved over time and identify trends and patterns that can inform your future marketing and [branding strategies](https://urlbox.com/brand-monitoring.md). As mentioned at the beginning of this article, certain industries are subject to regulatory requirements that mandate the archiving of social media and web content. By implementing a data archiving strategy and using tools like [Urlbox](https://urlbox.com/pricing.md), you can ensure compliance with these requirements and avoid potential legal risks. ## Enhance your data archiving strategy with Urlbox By now, you should already know how important it is to have a comprehensive data archiving strategy in place. And one essential element of such a strategy is capturing website screenshots, as they visually represent your website's content and design. Urlbox is a [screenshot service API](https://urlbox.com/screenshot-api.md) that can help you capture and archive virtually any URL or HTML file in multiple formats, such as JPEG, PNG, PDF, and many more.

This makes it a valuable tool for any business looking to enhance its data archiving strategy. And the best part is that you can [use Urlbox for free](https://urlbox.com/pricing.md) for seven days, regardless of the plan you choose. Once the trial ends, you can choose between 4 plans with pricing starting at $19 per month. This will allow you to generate, capture and archive up to 2,000 screenshots each month. --- # How To Detect Annoying Website Overlays, Modals and Popups > It’s a wild, wild, web out there. There’s all sorts of odd servers, doing dodgy stuff when you visit them and take a screenshot. Source: https://urlbox.com/automated-screenshots/detect-annoying-website-overlays Last updated: 2022-03-21 --- In London, if a film, joke, your new jacket, etc, gets approval from your friends, you’ll hear: “Quality, mate. Quality” You want your users to be saying that same phrase when they see a quality screenshot in your app. You’ve invested months creating a quality user experience for your customers. The last thing you want is for it to be ruined by a lousy screenshot. It’s a wild, wild, web out there. There’s all sorts of odd servers, doing dodgy stuff when you visit them and take a screenshot. You’ve got cookie banners, modal overlays, paywalls, or just plain nasty broken pages and servers. It’s impossible to know what surprise awaits when you visit various sites and take a screenshot. So how do you handle all the oddness the world wild web throws at you? There are a few ways… ## 1. Manually replacing bad screenshots “This screenshot is broken” is an all too familiar customer support subject line. If you’ve maintained an app that includes screenshots and has users it’s only a matter of time before they start coming in. You’ll learn a lot about all the outliers and oddities out there. But often the fastest thing to do is manually take a screenshot, make some adjustments in photoshop and upload it. It’s not so bad doing this a few times a week. As usage grows it’ll become increasingly frustrating for you and your users. ## 2. Writing fixes for edge cases Few developers will be happy with a manual solution. You might consider every broken screenshot as a test case for a bug to be fixed. You’ll amend your screenshotting code to handle every edge case you find. From then on, those issues should not happen again. It’ll be a process of continuous improvement: Learning, fixing, screenshotting… Learning, fixing, screenshotting… This means your code responsible for taking screenshots, contains within it a history of fixes to deal with the odd websites that users have raised and you have fixed. Having been doing this for 9 years now, taking hundreds of millions of screenshots, we still come across new weird and wonderful render issues every single week. We find this fascinating and relish solving each one. But, understandably, that’s not everyone’s cup of tea. ## 3. Fixes For Specific Sites. Some problems are specific to certain websites. Your users might collectively have a few dozen that they’re most likely to screenshot. Making a recipe for each of them is often worth the investment. Tweaking the code taking the screenshot, such as adding a delay, clicking a certain element, hiding a certain element, etc. You can find a full list of options that resolve 99% of problems you’re likely to encounter here: [screenshot options](https://urlbox.com/docs/options.md). So, if the site you are screenshotting has an annoying banner blocking the good stuff, you can simply use the [hide\_selector](https://urlbox.com/docs/options.md#hide_selector) option and it will be gone… ## 4. Artificial Intelligence / Deep Learning. As a team who likes to keep up to date with the most recent advances in technology, at Urlbox we have recently been looking at using AI / Deep Learning to automatically tell us, or our users, when there’s an issue with a screenshot. Built using the Python Keras library, we have built, trained and deployed a Deep Learning Neural Network to automatically recognise successful or obscured screenshots. Like so... ![](/content/detect-annoying-website-overlays/image2.png) Successful ![](/content/detect-annoying-website-overlays/image1.png) Obscured Using hundreds of screenshots created by Urlbox of various websites, and then manually classified into different categories to train the model, the model initially achieved accuracy rates of 95% on unseen data. With some improvements to how we process the data and a further round of cleaning the data so remove the more ambiguous images, we finally managed to create a model that achieved an accuracy rate on (unseen data) of 98.75%. Which is very, very good. If you’re interested in learning how you can train and deploy a Deep Learning Neural Network, we have a more technical deep dive coming soon. We are considering extending the number of classifications, to include broken pages (500s, etc), paywall sites, and a model trained specifically to detect successful/ broken social media site screenshots. And of course, we are exploring how this can help our users... Want an end of day email with a summary of your successful vs unsuccessful screenshots from that day? Want an email alert when a site you are trying to screenshot seems to be having issues? ## Conclusion We would love to hear any ideas you might have about how you might find this useful. We have a ton of ideas on this, but we like learning about our users’ worlds, so we can make sure we are helping them in the best way possible. So these are some of the things we do, constantly, quietly, behind the scenes, for our users to make sure their screenshots are Quality, mate. Quality.

Source: https://urlbox.com/email-to-image Last updated: 2025-03-21 --- Just like we use [social media archive tools](https://urlbox.com/social-media-archive-tools.md) to keep track of promoted posts, or [website archive tools](https://urlbox.com/website-archive-tools.md) to protect against lawsuits, we should also archive emails for easy access and long-term preservation. Whether for legal compliance, data backup, or information retrieval, the ability to systematically store and access email communication is often a crucial requirement for individuals and businesses. One way to do this is by converting emails into images, minimizing the chances of data alteration, and maintaining a visual record that is easy to review and reference. In this article, we dive into the benefits of converting emails to images and look at a range of tools designed to make the archiving process a breeze. ## What is the purpose of archiving emails? Archiving emails guarantee the safety and integrity of the email content, protecting it from unauthorized alterations or other forms of compromise. If you convert emails to images, you create a visual, uneditable record of every correspondence. This strategy is valuable in various scenarios, including unexpected inspections or audits where proving compliance is essential. At the same time, when an employee leaves a company, having a secure and intact archive of their email communications safeguards against the loss of important information. ## Converting emails to images is a better email archiving technique Imagine not having to panic when an employee accidentally hits delete on essential emails or not needing to scramble through different platforms to find that one email you need. Converting emails to images places this power into your hands, making it a remarkably effective email archiving technique. It's like having a safety net for your emails, ensuring you always have access to them, tucked safely away, even if chaos strikes the original mailbox. Converting emails to images is incredibly easy. Regardless of the platform, every email from every mailbox will be stored under one account. No more jumping from one mailbox to another or from platform to platform, wasting precious time you could use more productively. More than that, when you convert emails to images, every little detail – from the font to the images and signatures – remains as is. There’s no risk of losing any element of your emails, ensuring you always have the complete, unaltered information at your fingertips. ## Automate email archiving by converting email to image with APIs APIs are game changers for automating your email archiving. They make the conversion and archiving of emails a hands-off task, saving you both time and headaches. Let’s look at three powerful APIs that will make your email archiving efficient and consistent. ### Urlbox ![image2](content/email-to-image/image2.png) Urlbox is a [screenshot service API](https://urlbox.com/screenshot-api.md) businesses use to generate images from web pages and HTML files. Its built-in Zapier connector is a game-changer when it comes to converting emails to images effortlessly. With it, you can create automated workflows that trigger the conversion process whenever a new email lands in your inbox. On the other hand, you can leverage Urlbox’s powerful API to integrate it directly with your app, regardless of the tech stack it's built on. Once integrated, your app can autonomously send requests to Urlbox to convert emails to images or HTML as they arrive. The archiving process isn't just about capturing emails; it's also about organizing and storing them efficiently. Urlbox shines here with its built-in Amazon S3 and no-code integrations. Urlbox’s [pricing plans](https://urlbox.com/pricing.md) are based on usage, making it a budget-friendly choice for various businesses. The "Lo-Fi" plan starts at $19 per month for up to 2,000 renders when billed monthly. As the volume of emails increases, you can move to the "Hi-Fi" or "Ultra" plans, priced at $49 and $99 per month for up to 5,000 and 15,000 renders, respectively. You can [try Urlbox for free for seven days](https://urlbox.com/signup/ultra-annual-a.md) before choosing a plan. ### Pagefreezer ![image1](content/email-to-image/image1.png) If you want to stay vigilant against specific keywords, phrases, or patterns on social media, you should try [Pagefreezer](https://urlbox.com/social-media-archive-tools.md). It has an advanced search functionally that helps you locate specific posts or comments – a feature handy for government agencies and financial institutions. Besides that, you can set up keyword monitoring and policy alerts for all your social media channels. One of Pagefreezer’s disadvantages is that it doesn’t have the option to automatically save records in multiple destinations simultaneously. For developers, the absence of an API to integrate with other apps might be a huge deal-breaker. In terms of pricing, Pagefreezer is very flexible. Plans begin at $99 monthly and increase as you require more customization or extra features. ### APIflash ![image3](content/email-to-image/image3.png) At its core, [APIflash](https://urlbox.com/apiflash-alternative.md) guarantees pixel-perfect screenshots and promises stability even under heavy load. It can detect the optimal timing for capturing screenshots, meaning it waits until the pages are fully loaded before capturing an image. All APIflash’s APIs are secured. Moreover, it offers a range of valuable features, such as parameters for capturing full-page screenshots, mobile-responsive captures, and precise viewport size controls. APIflash comes with a free plan offering 100 screenshots a month and several other paid plans, and users can even opt for a custom enterprise plan if they need to handle millions of screenshots per month. ## What is the best way to convert email to image at scale? You need to carefully weigh your options if you plan to convert hundreds of emails to images. Using an API is arguably the best approach. They are designed to handle vast volumes of data and requests. They also offer scalability, and they can adapt to your needs as your business grows. If you’re not technical enough or don’t have a development team, you can use APIs with integrations with platforms like Zapier. This helps you set up automated workflows – known as “Zaps” – to convert emails to images without writing a single line of code. ## FAQ Let’s answer some of your frequently asked questions. ### Can I save an email as a JPEG? Yes, you can save an email as a JPEG file. Services like Urlbox allow you to convert your emails to high-quality images. All you have to do is provide the URL of your email, and the service will take a screenshot of the entire page, saving it as a JPEG file. This functionality is beneficial for preserving the visual layout of an email, making it easier to share, present, or archive for future reference. ### How do I save an email as a PDF? If you view the email in a web browser, you can easily download the email as a PDF file by selecting the "Print" option and then choosing "Save as PDF" as the printer option. This method will save the entire email as a PDF file, including any images and attachments. If you want to automate this process, you can use Urlbox, which lets you convert a [webpage to a PDF](https://urlbox.com/automated-screenshots/convert-webpage-to-pdf.md) automatically. ### What is the point of archiving emails? Archiving emails helps keep your email inbox organized and ensures that essential messages are safely stored for future reference. You can free up space in your active inbox while retaining the ability to access older emails when necessary. What’s more, email archiving is essential for compliance with various regulatory requirements that require the preservation of communications for a certain period. ### What are the risks of archiving emails? One of the primary concerns is the security of archived emails. If the archiving solution is not secure, sensitive information in emails may be vulnerable to unauthorized access and data breaches. Also, the process of archiving emails may inadvertently lead to the loss of essential messages if not done meticulously. Users might archive emails with malware or phishing links, which can be a security risk if accessed later. --- # How Performance Cheats Broke Our Website Screenshots > What I discovered when debugging our latest customer reported edge case. Source: https://urlbox.com/automated-screenshots/how-performance-cheats-broke-our-website-screenshots Last updated: 2025-03-21 --- When I started Urlbox in 2012 I did not expect to still be finding fascinating new rendering edge cases in 2024. This post is the story of how we debugged the following [screenshot API](https://urlbox.com/screenshot-api.md) issue raised by a customer last week (shared with permission): > Occasionally there are eComm stores where it seems like no matter how much delay & wait\_until=requestsfinished, the images never seem to load. With full page, it seems some sites have wacky loading. > > With that said, this is rare. I'll include a few examples (where I put a 10 second wait to ensure): > > - [https://us.brightsport.com/collections/all](https://us.brightsport.com/collections/all) > - [https://lunafide.com/collections/best-sellers](https://lunafide.com/collections/best-sellers) The issue is that images are not loading on some e-commerce websites, making their Urlbox screenshots look like this: ![broken images in screenshot](/content/debugging-shopify-images/screenshot-broken-images.png) But when viewed in a regular browser, they look like this: ![actual website screenshot](/content/debugging-shopify-images/actual-website-screenshot.png) The second link shows a similar issue, with a loading spinner in the screenshot: ![lunafide loading broken](/content/debugging-shopify-images/lunafide-loading-broken.png) But in a regular browser, things are loading correctly: ![lunafide loading ok](/content/debugging-shopify-images/lunafide-loading-ok.png) ## First step: Confirm the issue When we receive an issue such as this one we always want to know which other [render options](https://urlbox.com/docs/options.md) the user is passing so that we can see if any of them might be causing the issue inadvertently. It also allows us to try and re-create the issue and confirm it on our end. The customer reported the issue with some example [render links](https://urlbox.com/docs/render-links.md). Render links are URLs that can be used to directly request a screenshot from Urlbox by passing the target url and any [render options](https://urlbox.com/docs/options.md) in the query string. The render links that the customer had crafted looked like this: ``` https://api.urlbox.com/v1/*****/png?delay=10000&wait_until=requestsfinished&full_page=true&hide_cookie_banners=true&click_accept=true&url=https://us.brightsport.com/collections/all ``` Lets make those options more readable by converting them into JSON format and explain what each one does: ```json { "url": "https://us.brightsport.com/collections/all", "format": "png", "delay": "10000", "wait_until": "requestsfinished", "full_page": "true", "hide_cookie_banners": "true", "click_accept": "true" } ``` - [url](https://urlbox.com/docs/options.md#url) - This is the url of the site that the user wants to take a screenshot of. - [format](https://urlbox.com/docs/options.md#format) - The user is requesting a `png` screenshot of the site. - [delay](https://urlbox.com/docs/options.md#delay) - Tells Urlbox to wait 10 seconds (10,000ms) before taking a screenshot. - [wait\_until](https://urlbox.com/docs/options.md#wait_until) - Waits until all network requests are complete before taking a screenshot. - [full\_page](https://urlbox.com/docs/options.md#full_page) - The user wants to receive a full page screenshot, i.e. the entire height of the website. - [hide\_cookie\_banners](https://urlbox.com/docs/options.md#hide_cookie_banners) - This instructs Urlbox to try to remove any cookie banners and other potential modals from the site before taking a screenshot. This is done by using CSS and JS to set the elements to `display:none !important;`. - [click\_accept](https://urlbox.com/docs/options.md#click_accept) - This option tells Urlbox to find buttons within cookie banner dialogs labelled "Accept" or similar, and send a click event to them, in an attempt to 'accept' storing cookies, thereby removing the banner from the screenshot. It is quite surprising that the images on this particular website are failing to load given that the user requested a 10 second delay, plus they also added in the `wait_until=requestsfinished` option. We'll try to run the request without any additional options to see if the issue still occurs. We can use our own developer sandbox to quickly load and run the screenshot request without any render options: ![confirming issue in sandbox](/content/debugging-shopify-images/confirm-sandbox.png) We can see the issue still occurs without any additional render options. Looking at our browser logs, I can see there are no obvious javascript errors coming from the browser. Time to try and re-create the issue locally... ## Second step: Try to re-create the issue locally When running the same screenshot request in my local development environment, the issue **does not** occur and the images are loading correctly. The main differences between my local environment and production are: 1. **Geography** - my location and IP address will be detected as being in the UK, whereas our servers are US based primarily. 2. **Platform** - my local machine is a macbook pro, whereas our headless browsers run in ubuntu-based containers. Additionally, my macbook has a GPU, however our regular headless browsers do not, although by default we run with the `--disable-gpu` chrome flag so gpu is disabled in both. (It *is* possible to run a Urlbox request on a browser with a gpu enabled, by setting the [`gpu`](https://urlbox.com/docs/options.md#gpu) option to true, exclusive to users on our [Ultra plan](https://urlbox.com/pricing.md).) Number 1 is easy enough to simulate, by connecting to a VPN with an IP address based in the US. For this I use Proton VPN. It would be unusual if a site was choosing to block images to US-based visitors, but let's test anyway. When running the request locally and connected to the VPN, the issue does not occur, so it is looking like a platform specific difference causing the issue. ![running ok locally](/content/debugging-shopify-images/running-locally.png) Number 2 is harder to simulate, but I'm aware that sites will sometimes do user-agent sniffing and serve different content based on the user-agent. Using urlbox, I can simulate this by setting the [`user_agent`](https://urlbox.com/docs/options.md#user_agent) option to set the user-agent in the Urlbox headless browser to match the user-agent of a regular chrome browser: ``` https://api.urlbox.com/v1/****/png?url=https%3A%2F%2Fus.brightsport.com%2Fcollections%2Fall&user_agent=Mozilla%2F5.0%20%28Windows%20NT%2010.0%3B%20Win64%3B%20x64%3B%20rv%3A89.0%29%20Gecko%2F20100101%20Firefox%2F89.0 ``` When running the request with the user-agent set to a regular chrome browser, the issue still occurs, so it doesn't appear to be user-agent sniffing that is causing the issue. ## Going Deeper: Inspecting the source Intrigued to find out what is preventing these pesky images from showing, I crack open the devtools in a regular chrome browser and take a look at the html of the images. ![inspecting img source](/content/debugging-shopify-images/inspecting-source.png) It looks like the images are using the `srcset` attribute but without any `src` attribute, (which is a bit surprising as I had thought that the `src` attribute was still required for them to work, but it appears not). Could this possibly be why the images fail to load for us? I don't think so, and a quick google for `puppeteer img srcset` doesn't throw up anything obvious. It's also interesting seeing the classnames `lazyautosizes` and `Image--lazyLoaded` along with the `data-srcset` attribute, this suggests that some kind of plugin is controlling the loading of these images. :::note There's also a `<noscript>` tag accompanying each `<img>`, presumably this is used as an image fallback for any visitors that have disabled javascript in their browsers. We can simulate running a browser with javascript disabled in Urlbox by passing the [`disable_js`](https://urlbox.com/docs/options.md#disable_js) option. When running with this option, the images *do* appear in the screenshot. However, the issue with disabling javascript is that it also disables most useful Urlbox features. For example, the customer in this case wanted a full page screenshot of the site. With javascript disabled, it isn't possible to take a full page screenshot, as we need to run javascript in order to determine the full height of the page. ::: Let's try and inspect the html from urlbox's headless browser and see if there is anything obvious. Since Urlbox also allows you to return the fully loaded html of the page, we can simply run the screenshot request again but with `format` option set to `html`. Again we'll use our sandbox for this: ![running html request in the sandbox](/content/debugging-shopify-images/html-sandbox.png) We can also use the [`download`](https://urlbox.com/docs/options.md#download) option so that when opening our html, it will automatically download to our machine, using the filename specified in the download option. This just sets the content-disposition header which instructs your browser to download the file rather than open it in a tab: ``` https://api.urlbox.com/v1/****/html?url=https%3A%2F%2Fus.brightsport.com%2Fcollections%2Fall&download=remote.html ``` Opening the downloaded `remote.html` file, the first thing that strikes me is there are a lot of scripts - the `<head>` portion of the html is 414 lines long! The entire html file is 3676 lines long, so it seems like quite a hefty page with lots of third party assets such as scripts, stylesheets, iframes being loaded. There are also a lot of inline scripts in both the `<head>` and the `<body>`. It's clear from some of the asset URLs that this is a shopify store. Scrolling down to the `<img>` within the `<div class="ProductItem">`, it's obvious that in the working screenshot's html, the `img` tags have been enriched, presumably by some javascript inside a plugin, whereas in the remote screenshot html, the `img` tags don't appear to have been altered. You can see the diff between the two htmls below: ![local vs remote html diff](/content/debugging-shopify-images/local-remote-html-diff.png) Further, the working images have the class `Image--lazyLoaded` whereas the blank images have the class `Image--lazyLoad`. Doing a find all search for these classes in devtools brings me to this piece of embedded javascript in the `<head>`: ```html <script> // This allows to expose several variables to the global scope, to be used in scripts ... window.lazySizesConfig = { loadHidden: false, hFac: 0.5, expFactor: 2, ricTimeout: 150, lazyClass: 'Image--lazyLoad', loadingClass: 'Image--lazyLoading', loadedClass: 'Image--lazyLoaded' }; ... </script> ``` From a quick google, it looks like the site is using this [aFarkas/lazysizes](https://github.com/aFarkas/lazysizes) script to lazy load the images, and I can see where it is imported in the `<head>`: ```html <script async="" data-src="https://us.brightsport.com/cdn/shop/t/61/assets/lazysizes.min.js?v=174358363404432586981716100765" type="text/lazyload" ></script> ``` The github mentions that the lazysizes plugin includes a JS API that will add the `lazySizes` object to the `window`. In my local browser, I can see that the `window.lazySizes` is available. ![lazysizes object in local browser](/content/debugging-shopify-images/window-lazysizes.png) Now I would like to know what happens when I run `window.lazySizes.init()` in the console. Luckily, Urlbox allows us to run javascript in the context of the running page by passing the [`js`](https://urlbox.com/docs/options.md#js) option, so I can give it a try: ``` https://api.urlbox.com/v1/****/png?url=https%3A%2F%2Fus.brightsport.com%2Fcollections%2Fall&js=window.lazySizes.init() ``` Alas, no dice, the images are still not showing up. In order to really get to the bottom of what is going on I need to debug interactively in the remote headless browser... ## Debugging in production with devspace At urlbox, we host our headless browsers in containers within managed kubernetes clusters. Being able to debug in an environment as close to production as possible is sometimes essential in order to re-create and figure out what might be causing differences between our local environment and our production setup. We're going to use a handy tool called [Devspace](https://www.devspace.sh/?ref=urlbox) created by [loft.sh](https://loft.sh?ref=urlbox) to debug in a production-like environment. Devspace allows us to use the exact same container image as we use in production, but override some of its configuration to make it act like a development environment. For example, we can override the `entrypoint` or the `command` of the container to run a different command. Once configured, Devspace also syncs our local src files with the container, so we can make changes to the code and see the effects in real-time. Additionally, Devspace allows us to forward ports from the container to our local machine, so we can set breakpoints and debug within our nodejs process running in the container. Here's a sample of our `devspace.yaml` file: ```yaml version: v2beta1 name: urlbox pipelines: dev: run: |- start_dev renderer dev: renderer: env: - name: LOG_LEVEL value: "debug" labelSelector: app: renderer-debug workingDir: /home/urlbox/apps/renderer command: ["./entrypoint-debug.sh"] sync: - path: ./apps/renderer/config/entrypoint-debug.sh:/home/urlbox/apps/renderer/entrypoint-debug.sh disableDownload: true startContainer: true onUpload: exec: - command: |- chmod +x entrypoint-debug.sh restartContainer: true - path: ./apps/renderer/src:/home/urlbox/apps/renderer/src disableDownload: true excludePaths: - node_modules - path: ./apps/renderer/package.json:/home/urlbox/apps/renderer/package.json disableDownload: true onUpload: exec: - command: |- cd ../../ && yarn install --production=false restartContainer: true ports: - port: "6000" - port: "9229" ``` This sets up a pipeline called `dev` which looks for a pod running in our cluster with a label of `app` equal to `renderer-debug`. Once it finds such a pod, it will create a new devspace controlled pod using the exact same image as our pod, but overrides the `command` to run `./entrypoint-debug.sh`. In the `sync` section, we sync the `entrypoint-debug.sh` script and make it executable `onUpload`. This entrypoint-debug script installs some developer tools like [`nodemon`](https://github.com/remy/nodemon) and [`ts-node`](https://github.com/TypeStrong/ts-node) which allows us to restart the nodejs process whenever a typescript src file is changed. We change the way our node app is run - instead of `node dist/server.js` we change it to `nodemon --inspect src/server.ts` and nodemon will use ts-node to transpile our changed typescript files on the fly. The `--inspect` command line flag lets us attach a remote debugger for our node app on port 9229. We also tell devspace to sync our local `./apps/renderer/src` directory with the `/home/urlbox/apps/renderer/src` directory inside the container. We add environment variables inside the container using the `env` section, for example here setting the `LOG_LEVEL` to `debug`. Finally, we forward the container's `6000` and `9229` ports to our local machine. To start devspace, we call `devspace dev` in the terminal. This will run the dev pipeline, and once ready we can start making requests to our remote container using `http://localhost:6000`. ```bash $> devspace dev info Using namespace 'default' info Using kube context 'cluster-1' dev:renderer Waiting for pod to become ready... dev:renderer Selected pod renderer-debug-devspace-774659cbb8-lm9qz dev:renderer ports Port forwarding started on: 6000 -> 6000, 9229 -> 9229 dev:renderer sync Sync started on: ./apps/renderer/config/entrypoint-debug.sh <-> /home/urlbox/apps/renderer/entrypoint-debug.sh dev:renderer sync Waiting for initial sync to complete dev:renderer sync Sync started on: ./apps/renderer/package.json <-> /home/urlbox/apps/renderer/package.json dev:renderer sync Waiting for initial sync to complete dev:renderer sync Sync started on: ./apps/renderer/src <-> /home/urlbox/apps/renderer/src dev:renderer sync Waiting for initial sync to complete dev:renderer sync Initial sync completed ``` We can attach the chrome devtools to the remote nodejs process by navigating to `chrome://inspect` in a local chromium based browser and clicking `Inspect` when our remote nodejs target shows up. Now we're able to set breakpoints in the nodejs process from within chrome devtools. You could also attach debuggers from your IDE if you prefer. To be able to attach to the chromium browsers debugger, we'll first need to modify the part of our code that launches the browser to expose the remote debugging port. We can do this by adding the `--remote-debugging-port=9222` and `--remote-debugging-address=0.0.0.0` chromium flags to the `puppeteer.launch` options. ```typescript await puppeteer.launch({ headless: true, args: [ ... other chrome flags... '--remote-debugging-port=9222', '--remote-debugging-address=0.0.0.0', ] }) ``` When we save this change, devspace will automatically sync the file with the code in our container, then nodemon will notice that a file has changed and restart our node process. Now when we make a request to the container, Puppeteer will launch the browser with the additional debugging flags. We port-forward the remote debugging port, 9222 in our case, to our local machine, so that we can attach a debugger to the remote browser's devtools: ```bash kubectl port-forward renderer-debug-devspace-774659cbb8-lm9qz 9222:9222 ``` And we tail the logs of the container to see the output: ```bash kubectl logs -f renderer-debug-devspace-774659cbb8-lm9qz ``` In `chrome://inspect`, we can see the remote browser target and click `inspect` to open the devtools: ![remote browser target](/content/debugging-shopify-images/remote-browser-target.png) We can see how the website looks, and observe that the images are not loaded. In the console, I'll try to run `window.lazySizes.init()` to see if that makes a difference: ![remote browser console](/content/debugging-shopify-images/remote-browser-console.png) ```bash > window.lazySizes.init() VM656:1 Uncaught TypeError: Cannot read properties of undefined (reading 'init') at <anonymous>:1:18 ``` It looks like `window.lazySizes` is undefined in the remote browser. This is interesting, as we know that the lazysizes script is being loaded in the head of the html. There are no javascript errors in the browser console, suggesting there aren't any issues executing the script. Perhaps the script isn't even being executed at all? Let's see if `jQuery` or `$` is available in the remote browser, since a jquery script is also referenced in the head of the html: ```bash > jQuery VM576:1 Uncaught ReferenceError: jQuery is not defined at <anonymous>:1:1 (anonymous) @ VM576:1 --- > $ ƒ $() { [native code] } ``` So it looks like the jquery script is also not loaded. -> The `$` here is actually a chrome devtools function that acts like an alias for `document.querySelector`. If it was the `$` from jQuery, we wouldn't see `[native code]` in the printed function description. Let's check the network tab to see if the scripts are even being downloaded: ![scripts downloaded](/content/debugging-shopify-images/scripts-downloaded.png) It looks like the lazysizes and jquery scripts are being downloaded, but somehow they're not being executed. ## Suspicious MutationObserver scripts Looking through some of the inline scripts in the html of the page, I'm drawn to some code which seems to be using a `MutationObserver` to modify the innerHTML of other script tags, it also removes the `src` attribute of certain script tags. ```js const observer = new MutationObserver((e) => { e.forEach(({ addedNodes: e }) => { e.forEach((e) => { 1 === e.nodeType && "SCRIPT" === e.tagName && (e.innerHTML.includes("asyncLoad") && (e.innerHTML = e.innerHTML .replace( "if(window.attachEvent)", "document.addEventListener('asyncLazyLoad',function(event){asyncLoad();});if(window.attachEvent)" ) .replaceAll(", asyncLoad", ", function(){}")), e.innerHTML.includes("PreviewBarInjector") && (e.innerHTML = e.innerHTML.replace( "DOMContentLoaded", "asyncLazyLoad" )), e.className == "analytics" && (e.type = "text/lazyload"), (e.src.includes("assets/storefront/features") || e.src.includes("assets/shopify_pay") || e.src.includes("connect.facebook.net")) && (e.setAttribute("data-src", e.src), e.removeAttribute("src"))); }); }); }); observer.observe(document.documentElement, { childList: !0, subtree: !0 }); ``` To quickly test whether this is causing the issue I can set `window.MutationObserver` to null and observe if it makes any difference. In Puppeteer, we can use the [page.evaluateOnNewDocument](https://pptr.dev/api/puppeteer.page.evaluateonnewdocument) function to run scripts in the document *before* a page has been loaded. By setting MutationObserver to null, we can prevent them being instantiated by the page's scripts. Let's try this: ```typescript await page.evaluateOnNewDocument(() => { window.MutationObserver = null; }); ``` and re-run the screenshot request: ![mutation observer disabled](/content/debugging-shopify-images/mutation-observer-disabled.png) Lo and behold, the images are now loading correctly in the remote browser! We also have quite a few `TypeError: MutationObserver is not a constructor` errors in the remote browser, which correspond to all of the places where a new `MutationObserver` is being instantiated. By jumping to the source of each of these errors in the console, we can see how the `MutationObserver` is being used. **And it looks like we have found our culprit...** The second error in the console is coming from a script that looks like this: ```js if (navigator.platform == "Linux x86_64") { var lazy_css = [] , lazy_js = []; function _debounce(a, b=300) { let c; return (...d)=>{ clearTimeout(c), c = setTimeout(()=>a.apply(this, d), b) } } window.___mnag = "userA" + (window.___mnag1 || "") + "gent"; window.___plt = "plat" + (window.___mnag1 || "") + "form"; try { var a = navigator[window.___mnag] , e = navigator[window.___plt]; window.__isPSA = (e.indexOf('x86_64') > -1 && a.indexOf('CrOS') < 0), window.___mnag = "!1", c = null } catch (d) { window.__isPSA = !1; var c = null; window.___mnag = "!1" } window.__isPSA = __isPSA; if (__isPSA) var uLTS = new MutationObserver(e=>{ e.forEach(({addedNodes: e})=>{ e.forEach(e=>{ 1 === e.nodeType && "IFRAME" === e.tagName && (e.setAttribute("loading", "lazy"), e.setAttribute("data-src", e.src), e.removeAttribute("src")), 1 === e.nodeType && "IMG" === e.tagName && ++imageCount > lazyImages && e.setAttribute("loading", "lazy"), 1 === e.nodeType && "LINK" === e.tagName && lazy_css.length && lazy_css.forEach(t=>{ e.href.includes(t) && (e.setAttribute("data-href", e.href), e.removeAttribute("href")) } ), 1 === e.nodeType && "SCRIPT" === e.tagName && (e.setAttribute("data-src", e.src), e.removeAttribute("src"), e.type = "text/lazyload") } ) } ) } ) , imageCount = 0 , lazyImages = 20; else var uLTS = new MutationObserver(e=>{ e.forEach(({addedNodes: e})=>{ e.forEach(e=>{ 1 === e.nodeType && "IFRAME" === e.tagName && (e.setAttribute("loading", "lazy"), e.setAttribute("data-src", e.src), e.removeAttribute("src")), 1 === e.nodeType && "IMG" === e.tagName && ++imageCount > lazyImages && e.setAttribute("loading", "lazy"), 1 === e.nodeType && "LINK" === e.tagName && lazy_css.length && lazy_css.forEach(t=>{ e.href.includes(t) && (e.setAttribute("data-href", e.href), e.removeAttribute("href")) } ), 1 === e.nodeType && "SCRIPT" === e.tagName && (lazy_js.length && lazy_js.forEach(t=>{ e.src.includes(t) && (e.setAttribute("data-src", e.src), e.removeAttribute("src")) } ), e.innerHTML.includes("asyncLoad") && (e.innerHTML = e.innerHTML.replace("if(window.attachEvent)", "document.addEventListener('asyncLazyLoad',function(event){asyncLoad();});if(window.attachEvent)").replaceAll(", asyncLoad", ", function(){}")), (e.innerHTML.includes("PreviewBarInjector") || e.innerHTML.includes("adminBarInjector")) && (e.innerHTML = e.innerHTML.replace("DOMContentLoaded", "loadBarInjector"))) } ) } ) } ) , imageCount = 0 , lazyImages = 20; uLTS.observe(document.documentElement, { childList: !0, subtree: !0 }) } ``` This semi-obfuscated script is using a `MutationObserver` to remove the `src` attribute of `script` tags, but only if the `navigator.platform` is `Linux x86_64`. According to [MDN](https://developer.mozilla.org/en-US/docs/Web/API/Navigator): > The Navigator interface represents the state and the identity of the user agent. It allows scripts to query it and to register themselves to carry on some activities. > > A Navigator object can be retrieved using the read-only window\.navigator property. Clearly, this code won't run on our local machines, as the `navigator.platform` will be `MacIntel` or similar. If we can get our headless browsers to report their navigator.platform as something other than `Linux x86_64`, then this code won't run in production either. A simple way to do this is to use the `page.evaluateOnNewDocument` function again this time to set `navigator.platform` to `MacIntel`: ```js await page.evaluateOnNewDocument(() => { Object.defineProperty(navigator.__proto__, "platform", { get: () => "MacIntel", }); }); ``` Let's remove the code which disables the `MutationObserver` and re-run the screenshot request with the changed `navigator.platform`: ![navigator platform changed](/content/debugging-shopify-images/navigator-platform-changed.png) Yes, the images are now loading correctly in the remote browser! We will now turn this into a permanent fix by adding the `navigator.platform` override to our rendering code. We'll also make it an api option that can be set and overridden by the user, we'll default the value to `MacIntel`, so that our headless browsers don't get hit by these kinds of workarounds in the future. The problem is solved, but I still want to understand why a website would want to disable scripts based on a navigator.platform of `Linux x86_64`. ## Shopify plugins and faking performance metrics A google for '*shopify scripts linux x86\_64*' brings up quite a few results, especially this one from shopify's performance blog titled ["Don't get scammed by fake performance experts and apps"](https://performance.shopify.com/blogs/blog/don-t-get-scammed-by-fake-performance-experts-and-apps) which mentions that some shopify plugins and developers are purposely disabling scripts for linux based visitors in order to make their site appear faster in performance testing tools such as Google's Lighthouse: > We uncovered a set of apps and fake experts cheating the performance metrics. We found those practices in almost 15% of extensions that promised one-click optimizations. This means that a large number of merchant sites are affected. > > The main trick is to add a script that detects if the page is loaded using a speed testing tool. It then prevents the browser from loading most resources. These lighter pages achieve better scores, which help convince merchants that their money is well spent. However, no real improvement is achieved with real users meaning that visitors are still impacted by poor performance. and further down in the article, the exact technique used on this very shopify site is mentioned: > The most popular practices include: > > - Trying to prevent the loading of subsequent resources using the [Yett](https://github.com/elbywan/yett) library or [MutationObserver](https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver) directly. > > The `navigator.platform` property contains a string that identifies the platform on which the browser is running. At some point, performance cheaters decided that looking for the Linux x86\_64 value would be a good enough detection technique. Linux is often used for servers and has a small user base compared to other operating systems. This way, they can detect all tools running in data centers, not only the most popular ones. Of course this means that any human using Linux would also be affected. So it looks like the owner of this shopify site has installed an extension which is disabling scripts for linux based visitors in an attempt to make their site appear faster to performance testing tools. An unfortunate side effect for Urlbox users meant that this shopify performance hack also prevents some shopify sites from loading correctly in urlbox's renderer, meaning the screenshots were not as accurate as we would like them to be. ## Finding the plugin What's interesting about the particular script that causes this is that it is not coming directly from a file, as can be seen by the `VM521:1` in the console. The script is being `eval`'d by another script file. That offending script, is a file called [`globo_cart_mobile.js`](https://cdn.shopify.com/s/files/1/0644/2975/2553/t/2/assets/globo_cart_mobile.js) which contains this code: ```js eval(function(p, a, c, k, e, r) { e = function(c) { return (c < a ? '' : e(parseInt(c / a))) + ((c = c % a) > 35 ? String.fromCharCode(c + 29) : c.toString(36)) } ; if (!''.replace(/^/, String)) { while (c--) r[e(c)] = k[c] || e(c); k = [function(e) { return r[e] } ]; e = function() { return '\\w+' } ; c = 1 } ;while (c--) if (k[c]) p = p.replace(new RegExp('\\b' + e(c) + '\\b','g'), k[c]); return p }('l(r.O=="P y"){i j=[],s=[];u Q(a,b=R){S c;T(...d)=>{U(c),c=V(()=>a.W(X,d),b)}}2.m="Y"+(2.z||"")+"Z";2.A="10"+(2.z||"")+"11";12{i a=r[2.m],e=r[2.A];2.k=(e.B(\'y\')>-1&&a.B(\'13\')<0),2.m="!1",c=C}14(d){2.k=!1;i c=C;2.m="!1"}2.k=k;l(k)i v=D E(e=>{e.8(({F:e})=>{e.8(e=>{1===e.5&&"G"===e.6&&(e.4("n","o"),e.4("f-3",e.3),e.g("3")),1===e.5&&"H"===e.6&&++p>q&&e.4("n","o"),1===e.5&&"I"===e.6&&j.w&&j.8(t=>{e.7.h(t)&&(e.4("f-7",e.7),e.g("7"))}),1===e.5&&"J"===e.6&&(e.4("f-3",e.3),e.g("3"),e.15="16/17")})})}),p=0,q=K;18 i v=D E(e=>{e.8(({F:e})=>{e.8(e=>{1===e.5&&"G"===e.6&&(e.4("n","o"),e.4("f-3",e.3),e.g("3")),1===e.5&&"H"===e.6&&++p>q&&e.4("n","o"),1===e.5&&"I"===e.6&&j.w&&j.8(t=>{e.7.h(t)&&(e.4("f-7",e.7),e.g("7"))}),1===e.5&&"J"===e.6&&(s.w&&s.8(t=>{e.3.h(t)&&(e.4("f-3",e.3),e.g("3"))}),e.9.h("x")&&(e.9=e.9.L("l(2.M)","N.19(\'1a\',u(1b){x();});l(2.M)").1c(", x",", u(){}")),(e.9.h("1d")||e.9.h("1e"))&&(e.9=e.9.L("1f","1g")))})})}),p=0,q=K;v.1h(N.1i,{1j:!0,1k:!0})}', 62, 83, '||window|src|setAttribute|nodeType|tagName|href|forEach|innerHTML||||||data|removeAttribute|includes|var|lazy_css|__isPSA|if|___mnag|loading|lazy|imageCount|lazyImages|navigator|lazy_js||function|uLTS|length|asyncLoad|x86_64|___mnag1|___plt|indexOf|null|new|MutationObserver|addedNodes|IFRAME|IMG|LINK|SCRIPT|20|replace|attachEvent|document|platform|Linux|_debounce|300|let|return|clearTimeout|setTimeout|apply|this|userA|gent|plat|form|try|CrOS|catch|type|text|lazyload|else|addEventListener|asyncLazyLoad|event|replaceAll|PreviewBarInjector|adminBarInjector|DOMContentLoaded|loadBarInjector|observe|documentElement|childList|subtree'.split('|'), 0, {})) ``` This is clearly a very obfuscated script which when run will evaluate into the slightly less obfuscated script from above. It looks like this is from a plugin developer named [globo](https://globo.io/) based in Vietnam. Here are some of their shopify apps listed in the app store: [https://apps.shopify.com/partners/globo](https://apps.shopify.com/partners/globo) A [search on github](https://github.com/search?q=__isPSA\&type=code) for the string `__isPSA` also brings up very similar looking scripts, and a lot of [liquid templates](https://shopify.dev/docs/api/liquid), so it seems like this technique has been copied and pasted into multiple shopify plugins: ![github search](/content/debugging-shopify-images/github-search.png) ## Testing the fix on the other shopify site We can now test the fix on the other shopify site that the customer reported was having a similar loading issue. We'll set the `navigator.platform` to `Linux x86_64` and re-run the screenshot request: ![lunafide loading broken](/content/debugging-shopify-images/lunafide-loading-broken.png) and now with the `navigator.platform` set to `MacIntel`: ![lunafide macintel](/content/debugging-shopify-images/lunafide-macintel.png) So it appears that this site also had a similar plugin installed, and the platform fix works for this site too. Out of interest, I disabled the `MutationObserver` again in order to track down which script contained the performance hack. It turns out that the obfuscated code snippet is exactly the same here as it was on the other site, and it appears that it's been copied and pasted directly into the html `<head>`: ![lunafide eval code](/content/debugging-shopify-images/lunafide-eval.png) and when executed, becomes the same performance hack, relying on `navigator.platform` sniffing: ![lunafide performance hack](/content/debugging-shopify-images/lunafide-performance-hack.png) ## Conclusion In this article we've seen how we debugged a platform specific issue with a customer's screenshots, whereby images were not loading correctly and the site appeared to not have loaded. We went down many rabbit holes and got fooled by lots of red herrings. We used a combination of local development, remote debugging in a production-like environment, and inspecting the source of the website to find the root cause of the issue, which was caused by a rogue shopify plugin disabling scripts from loading if the browsers host platform was linux based. In the end the fix was quite simple, by overriding the `navigator.platform` property in the Urlbox headless browser, we were able to prevent scripts being disabled by the plugin, which meant the images on the page could now be lazy loaded correctly and start showing again. By fixing this issue, we also introduced a new option to our screenshot api: [`platform`](https://urlbox.com/docs/options.md#platform) which allows Urlbox users to set the `navigator.platform` property to a value of their choosing. --- # How to Generate X (previously Twitter) Screenshots Automatically Using X Screenshot Apps > Here’s an overview of the best X screenshot apps that help you generate X screenshots automatically. Read on! Source: https://urlbox.com/automated-screenshots/twitter Last updated: 2025-03-21 --- X is one of the most popular social networks on the Web today. People and businesses use X to build an audience and engage with potential customers. But it does have a massive drawback - it forces you to rely on its algorithm for visibility. Just think of that excellent thread you spent a few hours writing. It'd be a waste if the X algorithm were the only thing deciding if people get to read it. You have to share it across as many different channels as possible, starting with the ones you own, like your blog or newsletter. ![](/content/how-to-generate-twitter-screenshots-automatically/image3.png) X Screenshots Apps allow users to capture screenshots of their timelines or specific tweets. These apps are handy for creating content for blogs, articles, newsletters, and other social media platforms. This article will cover four ways to screenshot your tweets and generate high-quality, ready-to-share images automatically. ## How to generate X screenshots with Urlbox Urlbox is an all-in-one solution that helps you screenshot virtually any part of X, like: - A single Tweet - A profile page - A X list - A handle. Urlbox is a [screenshot API](https://urlbox.com/screenshot-api.md) at its core, but it also comes with Sandbox - a virtual playground. You can use this to generate a screenshot automatically and download it in many different formats, like PNG, JPEG, and even SVG or PDF. Urlbox is consider the most accurate way to [convert HTML to image](https://urlbox.com/html-to-image.md) and it works great on tweets. ### How to automatically screenshot a tweet 1\. Find the tweet you want to screenshot and copy its URL. 2\. Go to [publish.twitter.com](https://publish.twitter.com/) and paste in the URL you just copied. You can customize how the tweet looks by changing the theme between light and dark. You can also pick a different display language and even hide the conversation the tweet is part of. 3\. Once you are satisfied with how your tweet looks, just click Update and then copy the code. 4\. Sign in to your Urlbox account (you can start a free trial by going to [this page](https://urlbox.com/pricing.md)) and go to Sandbox. 5\. Switch from URL to HTML and paste the code you just copied. Select the "Element" Render Mode and use the ".twitter-tweet" selector. 6\. Once the image has been rendered, simply click on "Open in new tab" and save it. You can also upload all your screenshots to an S3 bucket. 7\. Use the Request URL to integrate Urlbox with your app to capture X screenshots automatically. ![](/content/how-to-generate-twitter-screenshots-automatically/image5.gif) How to screenshot other parts of X Say you want to screenshot a full profile once in a while to keep track of what other people are posting. In that case, all you have to do is: 1\. Go to [publish.twitter.com](https://publish.twitter.com/) and type in the handle of the profile you want to screenshot (for example, "@jot"). 2\. Pick the "Embedded Timeline" option, copy the code and paste it inside the Sandbox. 3\. This time, you'll have to pick the "Full page" render mode. This will make sure that your screenshot will feature all your latest tweets. You can also convert a public list's tweets into an image following these exact steps. ## Other X screenshot apps to keep in mind If you simply want to screenshot some tweets and you're not looking to automate the process, you can try one of the following apps. ### 1. Pikaso - Chrome Browser Extension ![](/content/how-to-generate-twitter-screenshots-automatically/image2.png) This app generates images from single tweets. It comes with a Chrome extension that adds the option to screenshot a tweet right on the platform. Pikaso is free as long as you're ok with a watermark on the final image output. If you want to get rid of the watermark, you'll have to pick a paid plan (starting at 9.99 EUR per month). This also grants you access to multiple output layouts and the ability to integrate it with Zapier. With the highest plan (199.99 EUR per month), you also get access to their [API](https://pikaso.me/api), which is extremely basic compared with the [Urlbox's API](https://urlbox.com/screenshot-api.md). One thing that makes Pikaso stand out is the ability to post your screenshots on Instagram automatically, but you will need Zapier to configure that automation. ### 2. Tweetpik - Screenshot tweets as videos ![](/content/how-to-generate-twitter-screenshots-automatically/image4.png) Tweetpik is one of the most complex X screenshot apps out there. It lets you screenshot, edit, and save single tweets. In addition, you can configure how the final image will look like by changing the X theme (light or dark), adding or deleting elements (number of likes, time posted, number of replies, etc.), and even adjusting the text width. Tweetpik also lets you create a video from a tweet that you can later post to your social. The app has a straightforward pricing plan starting at $12 per month (or $9 per month if billed yearly). Their paid plan comes with all features and up to 1,000 API requests/month. ### 3. Tweetshot - Screenshot tweets on your phone ![](/content/how-to-generate-twitter-screenshots-automatically/image1.png) All the apps I've covered until now work on desktop but don't have a mobile version. This is why I wanted to include Tweetshot in this list. You can screenshot single tweets straight from your phone, edit and save them in your gallery. Tweetshot comes with three different layouts you can pick from; it lets you edit the background color of the final image and change the X theme (light or dark). ## The best X screenshot apps Picking the right app boils down to what your end goal is. If you simply want to screenshot a single tweet, you can go with Tweetpik or Pikaso. If you're going to do so from your phone, you can give Tweetshot a try. If you need advanced features, like snapping X profiles, lists, or hashtags, you should pick Urlbox. You can also integrate the API with your app regardless of the stack you use. Urlbox works best for businesses and individuals looking for a scalable solution that automatically generates pixel-perfect X screenshots. The best part is that you can start with a [free trial](https://urlbox.com/pricing.md); this won't display any watermarks on your final image and grants you access to all features. --- # How to Take Full Page Screenshots - Best Tools and Most Common Use Cases > Follow step-by-step instructions on how to take full page screenshots and save them in different formats with the best tools and apps. Source: https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots Last updated: 2023-01-17 --- The process of taking full-page screenshots is straightforward, but things can get complicated depending on what you are going to use the screenshot for. You can use your browser's built-in functionality or an extension if you want to post a screenshot on your blog. However, you're going to need something a bit more advanced than an extension if you need to generate a [high-quality PDF document from a URL](https://urlbox.com/automated-screenshots/convert-links-to-pdf.md). Things get even more complicated if you need to take full-page screenshots automatically, say for an app you are developing. As a rule of thumb, the more screenshots you'll need, the more complex of a tool you'll have to use. This article covers the best tools for different use cases, so use the table of contents on the right to jump directly to your use case. ## Best tools to take a full-page screenshot of a single web page in Chrome Taking a screenshot is a pretty straightforward process regardless of the device you're on. Your laptop's keyboard has a dedicated key that captures your screen. Even your phone has a combination of buttons you can press to capture what's on your screen. But these built-in methods are only good at capturing what you see on your display. So what happens if you need to screenshot a full webpage? You can take multiple screenshots and put them together using an image editor, but that's a tedious process. Instead, here's a quicker way to achieve a better result by using Chrome's built-in functionality. ![](/content/how-to-take-full-page-screenshots/image2.png) 1. Navigate to the page you want to capture and press Ctrl + Shift + I simultaneously. This will open up Chrome's Developer Tools. 2. Resize your page to the aspect ratio you like. This is what the final screenshot will look like, so make sure to drag the Developer Tools panel to the right as much as possible. 3. Press Ctrl + Shift + P simultaneously and type in "Capture full-size screenshot," then click on the highlighted element or press Enter. Chrome will automatically take a full-page screenshot and save it as a PNG file on your device. 4. You can move the screenshot to another folder on your device or share it with a friend online. This method is the fastest as it doesn't require any additional extensions, but it has drawbacks. ### The page you screenshot has to be fully loaded For example, this method will not work if you want to capture your Twitter timeline (read more on [how to take perfect Twitter screenshots](https://urlbox.com/automated-screenshots/twitter.md)). At the same time, this method doesn't work if the page you are viewing has Lazy Loading images. Before taking the screenshot, make sure to scroll to the bottom so all images will be visible. ### The final screenshot will not be as wide as your screen Since you have to open the Developer Tools panel before taking the screenshot, your viewport will automatically get smaller. A solution to this problem is to configure the panel to pop up instead of displaying side-by-side with your window. To do so, click on the three dots in the panel's top right corner and Undock it from your window by selecting the first option under the "Dock Side" selector. ### The file size of your screenshot will be quite large Since Chrome only saves the image as a PNG file, your final file size will be relatively large. So if you plan to upload it on your website, you'll need to convert it to a better-optimized format, like WEBP or even a JPEG. Using Chrome's built-in functionality, taking full-page screenshots involves quite a few steps, so people thought of ways to streamline this process. That's why the [GoFullPage Chrome Extension](https://chrome.google.com/webstore/detail/gofullpage-full-page-scre/fdpohaocaechififmbbbbbknoalclacl?hl%3Den) was created. Over 5 million people use this lightweight add-on to capture a full-page screenshot instantly. Simply navigate to the Chrome Web Store, search for GoFullPage and click the "Add to Chrome" button. Next time you'll find yourself on a page you want to capture, click on the camera icon on Chrome's extension bar or press Alt + Shift + P. The extension will capture what's on your screen, then automatically scroll down and take another screenshot. This will repeat until the end of the page. Once your screenshot is done, it will take you to a page where you can save it as a PNG, JPG, or PDF file. As with the previous method, using GoFullPage also has a few drawbacks. ### The page you capture should not have any sticky elements This extension captures a bunch of screenshots and glues them together. As sticky elements will never leave your viewport, GoFullPage will capture them on each page render. If that's the case, you're better of with the first method or continue reading for an even better one. ### Waiting for the extension to finish scrolling the page Once you start the screen capture process, you will have to wait for the extension to finish scrolling the page. Your screenshot will be incomplete or unusable if you happen to scroll while the process is running. By now, you should have a pretty good idea of how to take a simple full-page screenshot, so it's time to move to something a bit more complex. ## How to take a full-page screenshot of a web page with sticky elements A sticky element can be extremely annoying if you want to screenshot a full page. You'll often find sticky headers, footers, or live chat bubbles. Some e-commerce stores even have sticky add-to-cart buttons, which can drastically alter the quality of a screenshot, sometimes rendering it completely useless. Moreover, when you take a full-page screenshot, you want to capture the webpage's contents without extra elements popping all over the final image. You'll need something a bit more advanced than a simple Chrome extension to achieve this result. ### Urlbox - the best screenshot tool that can hide certain page elements The best way to get rid of sticky elements on a screenshot is to hide them before rendering the final image. With Urlbox, you can do just that, plus more. First of all, you'll need to [create an account](https://urlbox.com/pricing.md). The cheapest plan starts at $19 per month, but you can sign up for a free trial before purchasing. ![](/content/how-to-take-full-page-screenshots/image4.png) Urlbox is not for everyone. If you simply need to take a single screenshot per month, you'd be better off editing the final screen capture image manually using a photo editor program. On the other hand, if you're planning to take multiple screenshots per month, Urlbox is the way to go. With your account created, you'll be redirected to your Dashboard. Next, you'll have to go to the Sandbox page, which you can access from the menu on the left of your screen. ![](/content/how-to-take-full-page-screenshots/image1.png) Type in the URL of the page you want to capture, select the output format, and click on the Full Page radio button. ![](/content/how-to-take-full-page-screenshots/image3.png) You'll need to scroll until you see the "Hide Selector" blocking option. This is where you'll have to paste the selector of the element you want to hide. ![](/content/how-to-take-full-page-screenshots/image5.png) To quickly get the CSS selector of any element on a webpage in Chrome, you'll have to right-click that element and click "Inspect." The developer tools panel will open up with that element highlighted. Simply right-click on it and select "Copy," then "Copy element." Once you paste in that CSS selector, click on the blue "Render button." Your full-page screenshot will be ready for download. Simply click on the "Open in new tab" button below your screenshot and save the image. You can also save the link for later or share it. You can use this to hide any element on a page, be it a sticky header, table of contents, or even cookie banners. Speaking of which, Urlbox has an extra option you can enable before taking your screenshot. Located just above the "Hide Selector" field, you can automatically configure Urlbox to accept cookies. This will ensure that your final image will not be altered by any cookie banner that might pop up on your viewport. I also find it important that you don't even need to have that page open, as all you need to generate a screenshot is a simple URL. This brings us to the next part of the article. ## How to take a full-page screenshot from a URL There are many online apps and services that can capture a full-page screenshot from a URL. So picking the right one boils down to what you plan to do with the final image. If you're looking for high quality, ready to share screenshots and don't shy away from spending $19 per month, you should pick Urlbox. Besides storing your full page screenshots for up to a month, you have various features and options to configure your final image. Moreover, Urlbox lets you select the output format of your screenshot, so you don't have to worry about converting the file after you download it. On the other hand, if you need a quick way to generate a single full-page screenshot from a URL without signing up for any service, you can give [site-shot.com](https://www.site-shot.com/) a try. You have to type in (or paste) the URL of the page you want to screenshot and select full-size. Pikwy.com is an even simpler version of Site-Shot. With a cleaner interface, it lets you quickly capture a full-page screenshot in a few seconds. I've tested it on multiple websites, and I find it very important to mention that it doesn't support lazy loading images, so if the web page you want to capture has that feature, you'd be better off with a better service. The last two services allow you to export your final file as either a PNG or JPEG image, so you'll have to convert it manually if you need a PDF (or any other type) file. Or you can pick the after route as I'm about to show you next. ## How to take a full-page screenshot and save it as a PDF We have dedicated a full article for this use case simply because it's extremely common, so if you want a complete overview of all the different ways and tools you can use to generate a PDF from a screenshot, be sure to [give it a read](https://urlbox.com/automated-screenshots/convert-webpage-to-pdf.md). To sum it up, the simplest and fastest way to generate a full-page screenshot and save it as a PDF is to [create an account](https://urlbox.com/pricing.md) with Urlbox, follow the steps I detailed earlier in the article, and select PDF as the output format. --- # How to Use an HTML to PDF API to Generate PDFs in Your Web Application > Here's how to use an HTML to PDF API to generate professional high-quality PDF files for your web application. Source: https://urlbox.com/html-to-pdf-api Last updated: 2023-01-13 --- Converting HTML to PDF files is a rather common functionality among web applications. Whether you need to generate an invoice for an e-commerce store, a bank statement, or even convert an article to a downloadable PDF, using an API is the best method to achieve all these because: - You can save a lot of time that would otherwise be spent creating your own conversion service - You don't have to worry about debugging your conversion code - You can implement this functionality regardless of your stack. In this article, you will learn how to use an [HTML to PDF API](https://urlbox.com/url-to-pdf.md) to generate professional high-quality PDF files. ## What is an HTML to PDF API? An HTML to PDF API is an application programming interface (API) that allows developers to convert HTML content into PDF documents. These APIs accept either an HTML file (including CSS and JavaScript) or an URL and generate a PDF document. Some HTML to PDF APIs can also output files in various different formats, like PNG, JPEG, SVG, or WEBP. Even though you might not need this functionality right now, you should plan ahead and get familiar with an API that can generate files in various formats. ## How do HTML to PDF APIs work? Most HTML to PDF APIs render a webpage or HTML file before capturing a screenshot and exporting it as a PDF document. You should keep in mind that some APIs struggle to render JavaScript or CSS correctly, so before you pick a service, make sure it can: - Correctly render modern frameworks like Bootstrap and Flexbox - Render and capture [full page screenshots](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md) - Hide specific elements by selector - Allow you to select the page size of the PDF - Change the documents' margins, orientation, and scale - Create and append headers and footers to the generated document - Block ads and automatically accept cookies or hide cookie banners One of the best HTML to PDF APIs on the market is Urlbox. It comes packed with all the above-mentioned features, plus more, so you can be sure your final PDF documents will look exactly as you want them. ## How to convert HTML to PDF with the Urlbox API Converting an HTML file or URL to a PDF document with Urlbox is extremely straightforward, as all you have to do is write a simple request like this: ``` https://api.urlbox.com/v1/\[API\_KEY\]/pdf?url=example.com ``` The above example works with a live URL, but if you want to convert HTML code (with inline CSS and JS), you can simply switch the last parameter, "url=", with "html=" and append the actual code. Here's an example of how it would look like: ``` https://api.urlbox.com/v1/\[API\_KEY\]/pdf?html=Enter%20your%20HTML%20to%20be%20rendered%20e.g.%20%3Chtml%3E%3Chead%3E%3C%2Fhead%3E%3Cbody%3E%3Ch1%3EMy%20HTML%3C%2Fh1%3E%3C%2Fbody%3E ``` In addition, you can configure how the PDF will look by using one or more of the (/docs/options#pdf-options)[PDF options](https://urlbox.com/docs/options.md#pdf-options) Urlbox has available: - pdf\_page\_size - pdf\_page\_width - pdf\_page\_heigh - pdf\_margi - pdf\_margin\_to - pdf\_margin\_righ - pdf\_margin\_botto - pdf\_margin\_lef - pdf\_scal - pdf\_orientatio - pdf\_backgroun - disable\_ligature - media ## How to allow users to download a PDF document generated from HTML Chances are you'll want users to be able to download the generated PDF document. The Urlbox API has a built-in functionality you can use to automatically create a download link for all the documents you create. All you have to do is append the "download" parameter to the request URL. Here's an HTML snippet that will create a download link for a PDF document named "my-document.pdf": ```html <a href="https://api.urlbox.com/v1/\[API\_KEY\]/pdf?url=example.com&download=my-document.pdf" >Download PDF</a > ``` The above example works for live URLs, but you can also generate a PDF from an HTML file and automatically create a download link for it. Here's another example of how that would look like: ```html <a href="https://api.urlbox.com/v1/\[API\_KEY\]/pdf?html=Enter%20your%20HTML%20to%20be%20rendered%20e.g.%20%3Chtml%3E%3Chead%3E%3C%2Fhead%3E%3Cbody%3E%3Ch1%3EMy%20HTML%3C%2Fh1%3E%3C%2Fbody%3E&download=my-document.pdf" >Download PDF</a > ``` It's important to keep in mind that your API key is embedded in the request URLs presented above. This means that anyone can potentially start using your key, so if you plan on implementing Urlbox in your web app, then you have to use an [authenticated request format](https://urlbox.com/docs/authenticated-requests.md), as explained in the [official documentation](https://urlbox.com/docs.md). ## How to convert HTML to PDF with any programming language As mentioned before, you can use a simple request URL to generate a PDF document from an HTML file or URL, but you can also seamlessly integrate Urlbox with your web app by writing a few lines of code. Here are a few examples covering the implementation of an HTML to PDF functionality in a web app for major programming languages: - [HTML to PDF Node.js](https://urlbox.com/url-to-pdf.md#url-to-pdf-in-nodejs) - [HTML to PDF Ruby](https://urlbox.com/url-to-pdf.md#url-to-pdf-in-ruby) - [HTML to PDF PHP](https://urlbox.com/url-to-pdf.md#url-to-pdf-in-php) - [HTML to PDF JAVA](https://urlbox.com/url-to-pdf.md#url-to-pdf-in-java) - [HTML to PDF Python](https://urlbox.com/url-to-pdf.md#url-to-pdf-in-python) - [HTML to PDF C#](https://urlbox.com/url-to-pdf.md#url-to-pdf-in-c) These are just a few examples, but you can always contact the Urlbox team if you need help with any other programming language.

Here's a list of other methods, tools, and APIs you can try: - wkhtmltopdf Library- You can create your own microservice using a library, but this means extra development hours, not to mention the final PDF will most likely be of poor quality. - PDFmyURL API- This is another type of API that allows you to convert URLs to PDFs. It's not clear if it works with HTML files. - HTMLPDFAPI - An API built specifically to convert HTML files to PDF documents. It's a bit pricier than the other solutions, plus we are not sure how well it can render complex web pages. It's important to try multiple tools before you settle on a specific one so you can get a feel of how they work and if they are exactly what your project needs. You can [start with Urlbox](https://urlbox.com/pricing.md), perhaps the most comprehensive yet easy-to-use HTML to PDF API. --- # Online Reputation Monitoring Tips and Best Practices > Monitoring your online reputation is essential to maintain a positive brand image. Read on to discover tips and best practices. Source: https://urlbox.com/online-reputation-monitoring Last updated: 2025-03-21 --- Maintaining a solid online reputation is one of the most critical aspects of success for your business, regardless of your industry. As the world is becoming increasingly digital, it's essential to stay ahead of the curve and develop a comprehensive reputation management strategy. A [study conducted by Dimensional Research](http://cdn.zendesk.com/resources/whitepapers/Zendesk_WP_Customer_Service_and_Business_Results.pdf) found that 54% of respondents who had shared a bad experience shared it more than five times, compared to 33% of those who had shared a good interaction. All these mean that you must quickly identify bad reviews and mentions and address them as soon as possible to maintain healthy growth for your business. This article will teach you tips and best practices to help you effectively monitor and manage your online reputation. ## What is online reputation monitoring? Online reputation monitoring is the process of tracking and managing a business's presence and reputation on the internet. This process can include tracking your business's online reviews and ratings on sites like Yelp, Trustpilot, or G2 and monitoring your presence on social media. This is extremely important for your business because it lets you stay aware of what is being said about your company online, so you can quickly and appropriately address any issues or negative feedback. ## How is online reputation monitoring done? The best way to monitor your online reputation is to set up automated alerts for when your business is mentioned online so that you can stay on top of any new developments. Going one step further, you should [website](https://urlbox.com/website-archive-tools.md) so you can later analyze any issues your customers might have had and stay ahead of any compliance issues. ## Why should you monitor your online reputation? Monitoring your online reputation is essential to maintain a positive brand image. With the right online reputation management strategy, you can protect your brand by keeping a close eye on what is being said online so you can respond quickly to criticism and address customer concerns. Here are more reasons why you should monitor your online reputation: - Boost credibility - People are more likely to trust a business that answers questions and tries to fix all customer issues promptly - Increase customer experience - A happy customer is more likely to continue doing business with a brand that quickly helps them - Get business insights - Monitoring and keeping records of your online presence can help you make better business decisions by showing you what customers love about your brand and what they don't - Rank higher on Google - Good reviews can help your brand rank higher on Google, which can result in higher revenue and conversion rate. You can see what people say about your brand by keeping an eye on your social media and review websites. Still, doing this manually increases the risk of missing out on valuable feedback or concerns. As I mentioned, using a [brand monitoring tool](https://urlbox.com/brand-monitoring-tools.md) is one of the best ways to keep track of your online reputation. This will drastically reduce the time spent searching and reading through tens of websites so that you can focus on your customers and business. ## How to choose an online reputation monitoring tool? You should look for multiple features when choosing an online reputation monitoring tool. Certain businesses may benefit from custom-made solutions – for example, a product that monitors hotel reviews – while others may only need some of that functionality. As a rule of thumb, here are the main features you should look for when picking an online reputation-monitoring tool: - Ease of use - You should spend time replying to feedback and analyzing data, so the tool you pick must be easy to use. - Works with all mediums - Monitoring your online reputation involves looking over multiple websites like social media platforms, forums, and review aggregators. The tool you pick should be able to track your presence everywhere online. - Export and storage options - A good online reputation monitoring tool should offer export and storage options so you can collect and store all data in one place. Some tools come with integrated AI (Brandwatch, Reputology), which can analyze and rate your online reputation, but they struggle to cover all mediums. And since people can discuss your brand anywhere online, it's better to rely on a tool that can help you monitor and archive conversations on any website. ## Urlbox - Best Tool To Monitor Online Reputation Urlbox is a screenshot service API that can snapshot any webpage by its URL and convert it into an image file (JPG, PNG, SVG, PDF). You can link it to an S3 bucket or any cloud storage provider (Dropbox, Google Drive, etc.) by using the official [Zapier connector](https://zapier.com/apps/urlbox/integrations/google-drive). ### How to use Urlbox to monitor online reputation There are two ways in which you can leverage Urlbox's functionality to monitor your online reputation: 1. Via [API](https://urlbox.com/screenshot-api.md) - You can use the API to create your own service regardless of your tech stack. This functionality works best for businesses that have access to development resources. 2. Via [Zapier](https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier.md) - Connect Urlbox with thousands of apps with this no-code option. It works best for smaller businesses that want a quick way to start monitoring their online reputation. The way Urlbox works is universal, regardless of the method you choose. All you have to do [is sign up for a free trial](https://urlbox.com/pricing.md), compile a list of the URLs you want to monitor, set up the frequency, and find a place to store the files. ## Online reputation monitoring strategy example For this example, I will use Urlbox as the online reputation monitoring tool, Google Sheets as the data source, Google Drive for storage, and Zapier as the connector between all platforms. You will need a paid Zapier account for the no-code implementation to work. ### Step 1 - Compile a list of mediums to track The first step is to create a [Google Sheets](https://sheets.new) file to add all websites you want to track. Here are the most important mediums you should track regardless of your industry: - Review Aggregator Websites - Yelp, Trustpilor, BBB - Social Media Profile Pages - Facebook, Twitter, Linkedin, etc. - Social Media Interactions - [Twitter mentions](https://urlbox.com/automated-screenshots/twitter.md), Facebook comments, etc. - Forums - Subreddits of interest or search pages, Quora questions, and search pages - Google Search Pages - These will contain results for keywords of interest, like your brand name. Getting the URL of a search page is extremely simple. All you have to do is search for your brand name on a platform (be it Facebook, Google, or Reddit) and simply copy the URL of that page. You have to cover all variations if your business name gets misspelled often. Otherwise, you might be losing valuable data. Once the list is ready, you'll have to decide on the frequency with which it will be checked: - Weekly - For small businesses that are just getting started - Daily - For companies with a lot of social interactions - Hourly - For large companies with tens of thousands of customers or more. You can always change the monitoring frequency as your business grows. ### Step 2 - Configure the data-gathering process With your list ready, it's time to move on to the actual data-gathering process. You can use either Zapier (follow [documentation](https://urlbox.com/docs.md)). The fastest way is to use Zapier and connect it to the Google Sheet you just created. Then all you have to do is set up the frequency using the built-in Zapier automation and connect your cloud storage provider (Google Drive). If everything goes as expected, Urlbox will start capturing screenshots at your specified time interval, and Zapier will upload them to your Google Drive. ### Step 3 - Reach out to your customers and analyze the data The benefits of monitoring your online reputation will show after you gather enough data. Some businesses can wait up to a few months to have enough conversations and reviews to analyze. On the other hand, if you run a successful business with thousands of active customers, you can start analyzing the data after just a few weeks. Remember not to make assumptions based on an incomplete data set. It's safer to wait and gather more information before estimating how people feel about your business. The most significant benefit of using [Urlbox](https://urlbox.com/pricing.md) as your online reputation monitoring tool is that it automatically archives all screenshots. This means you can look back to see how your reputation evolves and take action if things don't go as planned. ## Why does online reputation matter so much? Businesses only grow if they have an expanding customer base. If people start having bad experiences with a particular brand, they will stop buying and tell others to stop doing business with that company. Online reputation can drastically influence revenue, so you must stay on top of any problems that may arise and always address negative feedback as quickly as possible. The faster you start monitoring your online reputation, the more data you can capture and analyze to make better business decisions.

Source: https://urlbox.com/save-screenshots-azure-blob-storage Last updated: 2025-11-10 --- If you're generating automated screenshots for your application, you'll eventually need a reliable place to store them. Azure Blob Storage is an excellent choice, especially if your infrastructure already runs on Microsoft Azure or you need enterprise-grade storage with flexible access controls. In this guide, I'll show you how to automatically save screenshots generated with Urlbox directly to your Azure Blob Storage container. You'll learn how to set up secure access using SAS tokens, configure storage paths, and implement best practices for managing your screenshot archive. ## Prerequisites Before you begin, you'll need: - An Azure account with an active subscription - A storage account created in Azure - A blob container created within that storage account - A Urlbox account ## Understanding SAS tokens and access policies Azure uses Shared Access Signature (SAS) tokens to grant limited access to your storage resources. Unlike traditional access keys that provide full account access, SAS tokens can be scoped to specific containers and permissions. Here's the important part: once you generate a SAS token, its permissions and expiry date are fixed. You can't modify them later. This is where **Stored Access Policies** become essential. With a stored access policy, you can: - Update the expiry date without regenerating the token - Modify permissions on the fly - Revoke access instantly by deleting the policy This means you can configure your Urlbox project once and manage access entirely from the Azure Portal. No need to update credentials in your application when tokens expire or permissions change. ## Setting up Azure Blob Storage with Urlbox Let's walk through the setup process step by step. ### Step 1: Create a stored access policy Navigate to your container in the Azure Portal and select **Access policy** under Settings. Create a new stored access policy with these settings: - **Identifier**: any-name-you-want - **Permissions**: Create, Delete (not needed, but recommended) Click **Add** to save the policy. **A note on permissions**: We recommend starting with just Create and Delete permissions. The Create permission allows Urlbox to upload renders, while Delete enables automatic cleanup of test files. Only add Write permission if you specifically need to use custom paths with the ability to overwrite existing files. We'll talk more about that later ### Step 2: Generate a container-level SAS token Navigate to your container and select **Shared access tokens**. Configure the token: - **Signing method**: Account key - **Stored access policy**: Select `the-policy-you-created-earlier` - **Permissions**: Will be inherited from your policy - **Allowed protocols**: HTTPS only Click **Generate SAS token and URL**. Copy the **Blob SAS token** from the output. It will look something like: `sv=2025-10-30` Keep this token secure - you'll need it for the next step. Remember, once you leave this page, you'll no longer be able to view, edit or delete a created sasToken. (This is why you want to control it's access via an Access Policy) ### Step 3: Configure Urlbox with your Azure credentials Log in to your Urlbox dashboard and navigate to your project settings. Scroll down to the **Azure Blob Storage Configuration** section. Click **Add Azure Config** and fill in: - **Account Name**: Your storage account name (e.g., `mycompanyscreenshots`) - **Container Name**: Your container name (e.g., `screenshots`) - **SAS Token**: The token you just generated Click **Save Azure Config**. Urlbox will upload a test file to validate the credentials. If your SAS token includes Delete permission, this test file will be automatically removed. Otherwise, you can safely delete it manually from the Azure Portal. ## Using Azure Blob Storage with Urlbox Now that everything is configured, saving screenshots to Azure is as simple as adding one option to your API request. ### Basic usage Now make a request with the URL you want to screenshot to `https://api.urlbox.com/render/async`: ``` curl -X POST \ https://api.urlbox.com/v1/render/async \ -H 'Authorization: Bearer your_urlbox_api_secret' \ -H 'Content-Type: application/json' \ -d ' { "url": "https://www.google.com", "use_azure": true } ' ``` The screenshot will be saved to your Azure container with the render ID as the filename. ### Using custom paths You can organize your screenshots with custom paths using the `azure_path` option: ``` curl -X POST \ https://api.urlbox.com/v1/render/async \ -H 'Authorization: Bearer your_urlbox_api_secret' \ -H 'Content-Type: application/json' \ -d ' { "url": "https://www.google.com", "use_azure": true, "azure_path": "screenshots/google/image.png" } ' ``` This will save the screenshot to `screenshots/google/image.png` in your container. **Important**: If you need to reuse the same path (overwriting existing files), your SAS token must include Write permission. However, be cautious - enabling Write allows files to be overwritten, which could result in unintentional data loss. Only enable it if you specifically need this capability. The response will include the full Azure Blob Storage URL where your screenshot is stored. Access to it depends on Anonymous Access on both Storage Account and Container. Remember that allowing anonymous read will allow anyone with the link to view the blob. ## Using Azure with render links If you want to use [render links](https://urlbox.com/docs/render-links.md) (synchronous rendering) with Azure, you'll need to configure anonymous read access on your container. This allows Urlbox to serve the screenshots directly from Azure. However, be careful with this approach - anyone with the link can access your files. For sensitive screenshots, it's better to use the asynchronous API and handle distribution through your own application. ## Troubleshooting common issues **"Permission denied" error** This usually means your SAS token lacks the required permissions. Verify that your stored access policy includes at least Create permission and it's not expired. **"Container not found" error** Double-check that your account name and container name are spelled correctly. **SAS token expired** If you used a stored access policy, you can extend the expiry date in the Azure Portal without regenerating the token. If you didn't use a policy, you'll need to generate a new token and update your Urlbox configuration. **Overwrite failed when using custom paths** If you're trying to upload to the same `azure_path` twice, you'll need Write permission in your SAS token. Update your stored access policy to include Write permission. ## Conclusion Azure Blob Storage provides a robust, scalable solution for storing automated screenshots. With Urlbox's built-in Azure integration, you can start archiving screenshots to your own storage with just a few configuration steps. The combination of SAS tokens and stored access policies gives you enterprise-grade security with the flexibility to manage access without touching your application code. Whether you're building a monitoring tool, creating a content archive, or generating screenshots for your application, Azure Blob Storage can handle your needs at any scale. Ready to get started?

Source: https://urlbox.com/automated-screenshots/save-twitter-thread Last updated: 2025-03-21 --- X threads allow users to go beyond the 280-character limit per tweet, helping them write stories or compelling arguments that would be impossible to express in just a few words. But revisiting these threads can be cumbersome, mainly because your feed is constantly updated with new tweets. In this article, we’ll cover the best ways to save and download X threads so you can read them anytime. You’ll learn the easiest way to save a thread and how to automatically download them by [capturing X screenshots at scale](https://urlbox.com/automated-screenshots/twitter.md). ## How to save a X thread in the official app The easiest way to save a X thread to read later is to bookmark it straight from the X app or website. All you have to do is: 1\. Click on the “Show this thread” link under the thread ![image6](/content/save-twitter-thread/image6.png) 2\. Click on the bookmark icon under it. ![image3](/content/save-twitter-thread/image3.png) Now you can view all your saved threads in your Bookmarks. ## How to save a X with third-party apps Reading threads directly on X can sometimes be challenging since they are a bunch of tweets displayed one under the other. That’s where a third-party thread reader app comes into play. These apps can turn a thread into a simple blog-like web page, including images and videos, making it much easier to follow the story. ### The Thread Reader App The [Thread Reader App](https://threadreaderapp.com/) is one of the most popular tools in this category and works in 4 different ways: 1. You can reply to any tweet within a thread, mentioning @threadreaderapp and including the keyword "unroll." 2. Alternatively, click Retweet > Quote Tweet on any tweet within a thread, mention @threadreaderapp, and include the word "unroll." In a few minutes, you’ll receive a reply from @threadreaderapp with a link to your easy-to-read X thread. 3. The third method doesn’t require a X account; all you have to do is go directly to the Thread Reader App and simply paste the X thread’s URL. ![image1](/content/save-twitter-thread/image1.png) 1. Last but not least, the fastest method to convert a X thread into a more readable format with the Thread Reader App is to paste “threadreaderapp.com/thread/” in front of the thread’s id inside the URL bar. ![image7](/content/save-twitter-thread/image7.png) Now that you have generated the thread, you can bookmark them inside the Thread Reader App to read later. You must sign up for a free account to access this functionality. ## How to save and download a X thread as a PDF in Chrome Some use cases for downloading a X thread could be downloading a copy to share on other platforms or creating a [social media archive](https://urlbox.com/social-media-archive-tools.md). Regardless of your goal, you can easily download a X thread as a PDF using Chrome. ### Download a thread directly from the X website If you want to download a thread directly from the X website, install a 3rd party Chrome extension. This is because the content of a thread is usually longer than your screen, meaning you’ll need to capture a [full-page screenshot](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md). The fastest way to capture a screenshot and download it as a PDF in Chrome is by pressing the “Ctrl” + “P” combo on your keyboard; this will result in a low-quality image. For the best results, you must use the [GoFullPage extension](https://chrome.google.com/webstore/detail/gofullpage-full-page-scre/fdpohaocaechififmbbbbbknoalclacl). This simple app scrolls through the webpage you are viewing and generates a full-page screenshot. All you have to do is open the thread and click the GoFullPage icon in your browser extension’s bar. Once it reaches the bottom, it will open a new tab featuring your final image. You can then download that image as a PNG, JPG, or PDF. The final image will include unwanted content, like the left and right bars, your X handle, and the “Messages” element. You must be logged in for this method to work; otherwise, the screenshot will feature the sticky “Log in” bar at the bottom of the page. If image quality is essential to you, you should generate a screenshot from a 3rd party thread app. ### Download a X thread from a 3rd party thread reader app This method can help you generate a high-quality, ready-to-share thread image. You can use the GoFullPage extension we covered earlier to capture a full-page screenshot of the thread as displayed by the Thread Reader App. This image will still contain unwanted elements, but you don’t need a X account to capture the screenshot. Alternatively, you can sign up for a Thread Reader App paid account for $3 per month. This will allow you to download the thread as PDF directly from the app’s dashboard. The image quality is not excellent, but it will not contain any unwanted elements. In addition, you can only download the thread as a PDF broken down into multiple pages, making it rather difficult to read and follow. So if you are looking for the highest possible image quality, use another app that can convert X threads into PNGs, JPEGs, and PDFs and can be configured to automatically capture screenshots at any given time based on any criteria. ## How to save X threads at scale with Urlbox Urlbox is a [screenshot service API](https://urlbox.com/screenshot-api.md) capable of generating pixel-perfect screenshots of any webpage. It can capture full-page screenshots or specific page elements and output images in multiple formats, including PNG, JPEG, PDF, WEBP, and more. You can use Urlbox to capture a screenshot in various ways: 1. Dashboard: the easiest way to capture a screenshot with Urlbox is by using its dashboard, as all you have to do is add your target URL, apply any configuration, click a button, and Urlbox will automatically generate a high-quality image. 2. Request URL: you can use the dashboard to create a Request URL featuring all your options, then simply change the target URL to match any X thread you want to convert to a PDF. Open the URL in your browser, and Urlbox will return a screenshot. 3. Zapier: you can use the official Urlbox-Zapier connector to automatically capture screenshots of X threads without writing a single line of code. This method also helps you connect Urlbox with thousands of different apps, opening up countless opportunities. 4. Code: you can integrate Urlbox into your application via API to capture screenshots automatically. This is a more technical method that works best for businesses. Regardless of your chosen method, the configuration to save and download a X thread as a PDF or in any other format will be the same. ### Save and download X threads at scale from the official website Before you start, you must sign up for a [7-day free trial with Urlbox](https://urlbox.com/pricing.md), then head on to the Dashboard section. The first step is to paste the X thread URL inside the URL box at the top of the page. ![image2](/content/save-twitter-thread/image2.png) Now select the “Element” option under the Render Mode settings. You must copy and paste this CSS selector in the “Selector” field: \[aria-label="Timeline: Conversation"] This instructs Urlbox to capture just the thread, not the whole X page. ![image8](/content/save-twitter-thread/image8.png) Next, we’ll use “Blocking Options” to instruct Urlbox to accept X’s cookies (which will hide the cookie notification bar at the bottom of the page in the final image). And to make the screenshot look even better, we’ll hide X’s login bar by hiding that element. Simply copy and paste this CSS selector in the “Hide Selector” field: \[data-testid="BottomBar"] ![image4](/content/save-twitter-thread/image4.png) Click the blue “Render” button at the bottom of the page, and Urlbox will automatically convert the X thread into an image. Here’s [what the final image](https://renders.urlbox.com/urlbox1/renders/621359868a4a91d98957a8e2/2023/5/19/b91eb651-9a26-46dd-b18f-adbaad412cde.png) [will look](https://renders.urlbox.com/urlbox1/renders/621359868a4a91d98957a8e2/2023/5/19/ce3324f8-5cf4-4f95-bac9-8cb3e4c5353e.png) [like](https://renders.urlbox.com/urlbox1/renders/621359868a4a91d98957a8e2/2023/5/19/b91eb651-9a26-46dd-b18f-adbaad412cde.png). You’ll notice the image still features some comments and a small blank section at the bottom. This is how X loads threads, so you must apply some extra configurations via code if you want to eliminate them, which is a bit more complicated and requires programming knowledge. You can either ask for the help of a developer or screenshot the thread from a 3rd party thread reader app. This configuration will work regardless of how you plan on using Urlbox. You can recreate it inside Zapier for no-code automation or copy the generated “Request URL” or “Options as JSON” inside your app or spreadsheets. You will find them on the right part of the screen. ![image5](/content/save-twitter-thread/image5.png) ### Save and download X threads at scale from the Thread Reader App As mentioned above, you can also capture a screenshot of the thread from a 3rd party app. In this example, we’ll use the Thread Reader App. You can use their built-in thread-to-PDF converter. Still, with Urlbox, you can integrate this functionality into your app or create any automated workflow using the Zapier connector. First, copy the thread URL from the Thread Reader App and paste it inside the Urlbox dashboard (or into the Zapier connector configuration). ![image9](/content/save-twitter-thread/image9.png) Next, select the “Element” render mode and paste this CSS selector in the “Selector” field: .col-12.hide-mentions ![image10](/content/save-twitter-thread/image10.png) Click the blue “Render” button, and that’s it! Here’s [what the final image](https://renders.urlbox.com/urlbox1/renders/621359868a4a91d98957a8e2/2023/5/19/b118b2df-8222-44c4-9251-3733cebea17e.png) [will look](https://renders.urlbox.com/urlbox1/renders/621359868a4a91d98957a8e2/2023/5/19/ce3324f8-5cf4-4f95-bac9-8cb3e4c5353e.png) [like](https://renders.urlbox.com/urlbox1/renders/621359868a4a91d98957a8e2/2023/5/19/b118b2df-8222-44c4-9251-3733cebea17e.png). You can also make the image look cleaner by hiding the buttons at the top of the page simply by pasting this selector in the Hide Selector field: .row\.mb-4 ![image11](/content/save-twitter-thread/image11.png) Here’s [what the final image will look like](https://renders.urlbox.com/urlbox1/renders/621359868a4a91d98957a8e2/2023/5/19/ce3324f8-5cf4-4f95-bac9-8cb3e4c5353e.png). ## What is the best way to save and download a X thread? The fastest way to save a thread is by bookmarking it in the X app or official website. However, if you want to save it as a PDF, you can use a 3rd party to screenshot the thread’s webpage or generate it from scratch. If you want to save and download X threads at scale and get high-quality images, go with Urlbox. It doesn’t matter if you are a programmer or prefer to use no-code tools; you can rely on Urlbox to generate pixel-perfect X screenshots that are ready to share. --- # How to Take Scrolling Screenshots at Scale > Discover three ways to capture scrolling screenshots at scale regardless of your technical knowledge. Source: https://urlbox.com/automated-screenshots/scrolling-screenshots Last updated: 2025-03-21 --- Taking [scrolling screenshots](https://urlbox.com/scrolling-screenshots.md), which capture an entire webpage in one image from top to bottom, can be a daunting and time-consuming task due to various factors such as sticky elements, lazy loading images, and emerging technologies like Flexbox.

Specify the URL - once you have your API key, specify the webpage URL you want to screenshot. You can also select other options, such as the viewport size, delay time, and user agent. 3. Set the scrolling options - next, set the scrolling options to tell Urlbox how to capture the scrolling screenshot. You can specify the scroll increment and time delay between each scroll. Urlbox also supports infinite-scrolling pages. 4. Capture the screenshot - once you have set the options, make a request to Urlbox with the specified parameters to capture the screenshot. Urlbox will automatically scroll the page and catch its entire length in a single image. 5. Save screenshot - optionally, save the screenshot to your preferred location in the cloud, export it to S3, or create a download link so anyone can access it. Capturing scrolling screenshots at scale with Urlbox is a quick and easy process that saves you time and effort. With its powerful API, you can capture high-quality screenshots of webpages at scale without hassle. Let's dive deeper into each method to see exactly how to take a scrolling screenshot with Urlbox. ## How to capture scrolling screenshots with the Urlbox API You will need an API key before anything else, so [sign up for the free trial](https://urlbox.com/pricing.md) to generate it. The next step is to construct an HTTP request using your API key as part of the URL query string and other parameters such as the target website URL, resolution size, and delay time for capturing the scrolling screenshot. Here is an example of how the request URL will look like: ``` https://api.urlbox.com/v1/{api_key}/png?full_page=true&url=https%3A%2F%2Furlbox.com&retina=true&block_ads=true&hide_cookie_banners=true ``` This request will generate a retina-ready, full-page screenshot of the urlbox.com website. It will automatically hide cookie banners and block ads so the final image will represent the webpage's content without distractions. In addition, the image format will be PNG, but you can always pick another one that better suits your needs. You can choose between JPG, WEBP, AVIF, SVG, PDF, and even HTML.

Here are detailed guides on how to make a request to Urlbox with the most common programming languages: - [NodeJS](https://urlbox.com/7-ways-website-screenshots-nodejs-javascript.md) - [Python](https://urlbox.com/website-screenshots-python.md) - [PHP](https://urlbox.com/website-screenshots-php.md) - [C#](https://urlbox.com/website-screenshots-c-sharp.md) - [Java](https://urlbox.com/website-screenshots-java.md). You can always read more in the [official documentation](https://urlbox.com/docs.md). ## How to capture scrolling screenshots with the Urlbox-Zapier connector If you don't know how to program or don't have the necessary resources available, you can create an automated workflow that will capture scrolling screenshots. You only need a Urlbox account, a premium Zapier account, and a database or online spreadsheet (Google Sheets, Airtable, etc.). We have already created a detailed guide on using this connector in [a previous post](https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier.md). ## How to capture scrolling screenshots with the Urlbox and Google Sheets This last method is the easiest and most cost-effective, as all you need is a Urlbox account and a few Google Sheets formulas. Here's precisely what you have to do: 1. Step 1 - Make a copy of this [Spreadsheet](https://docs.google.com/spreadsheets/d/1ysqKNUhSeue8aXXAaZUODHohpgdfrJ5OTFch6kYBVAo/copy) 2. Step 2 - [Sign up](https://urlbox.com/pricing.md) for Urlbox to get your API key 3. Step 3 - Paste your API Key in the green cell. 4. Step 4 - Add as many URLs as you want and select the output image format 5. Step 5 - Click on the Screenshot URL to inspect and save the final image. That's it. You can capture as many full-page screenshots as needed without setting up anything else. You can always improve on this and add extra functionality as you see fit. ## What is the best way to capture scrolling screenshots? The best way to capture [scrolling screenshots](https://urlbox.com/scrolling-screenshots.md) at scale depends on your specific business needs, technical knowledge, and your budget. If you want to automate the entire process and capture hundreds or thousands of screenshots at a time, then implement a screenshot service API into your application. On the other hand, if you don't have a dedicated programming team or don't know how to code yourself, you can use Zapier to automate this process. ## FAQ Find answers to frequently asked questions about scrolling screenshots. ### How to capture scrolling screenshots on Windows?

Have you considered using Selenium? I have and I tested many other tools so you don't have to. Source: https://urlbox.com/selenium-alternatives Last updated: 2025-10-13 --- You might have found yourself in need of automating screenshots of one or more web pages. If you are a developer, you've probably heard of Selenium, a standard when it comes to automating web browsers. But are you sure it's the best tool for the job? When taking screenshots, you might need them for compliance, UX research, cross-browser testing, competitor monitoring, or any number of other reasons. But you want the pictures to look great—at least as good as they would if you were manually taking them from your OS. In this article, I will help you compare Selenium and some of its alternatives to help you get the screenshots you need. ## But Why Not Selenium? Before we explore alternatives, why not just go with the standard browser automation tool? It’s been around for ages and is usually the go-to when developers need to automate browser tasks for testing, debugging, and more. I’ve done a comparison for you. I took these screenshots from Windows 11 Snipping Tool and Selenium. To get these images I’ve set up a Virtual Machine on Oracle, installed Selenium, Chrome WebDriver, Node, NPM and a few other stuff. Once set up, it was time to get coding. After a lot of troubleshooting I had a beautiful script.js to run via SSH. The image quality overall is not that bad. CSS loads well, the fonts from the example websites were loaded correctly but media is a problem. Nike has an autoplay video that Selenium did not start and displayed the video controls instead. Also, the pages did not render fully because the height was not dynamic, further coding would be necessary. For every new page I will need a lot of coding and troubleshooting. Can I investigate and fix the issue with Adobe? What about Nike’s video? How much time would I spend troubleshooting? How do I take these screenshots via HTTP or from my own application instead of using ssh? This is exactly why we are exploring alternatives. For every issue we have with Selenium, we must spend hours to fix it. It is an automation tool, and we must automate the behaviour for every different page, we must also wrap it around any service we would like to turn it into, and then we should also maintain our newly created API. ## How Do I Choose the Best Tool? Finding the right tool can be quite subjective, as each user has their own specific needs to fulfill. However, I believe some of the most common factors to consider are: **accuracy**, because regardless of why you need the screenshots, they must reflect what you'd see when browsing the webpage in an up-to-date browser. Fonts should render correctly, media must load properly, and your CSS must be in place. **Reliability**, because no matter how many screenshots you're taking, you need to trust that the software will work when you expect it to. And **customization**, because while needs may vary, a tool with robust customization options is more likely to let you tailor it to your exact requirements. Then comes **speed** — some cases require the screenshots to be ready within less than 3 seconds. While some prefer the peace of mind of the next point. **Security** — maybe you have a specific request with sensitive information and you don’t want that to be exposed. Bear in mind that additional security measures may have a direct impact on speed. And finally, **initial cost**. As you’ve noticed on the Selenium example, an extensive setup can get quite costly in terms of development time and costs. Instead of creating your own Screenshot service, you might want to consider stuff that’s already out there. ## 10 Selenium Alternatives for Website Screenshots I tested some of the most popular screenshot tools and compared them based on the following criteria: - Onboarding - How hard it is to get the first screenshot, automate and tweak options - Accuracy and Quality - Image definition and content display - Speed - For all-in-one services, we collected the average time to render different sized pages with the service default options. Services that do not provide an API were not tested for speed. - Customization - How much control do you have over the screenshot. ## Urlbox *Great user interface for one-off screenshots and API setup. Great consistency.* At first glance, UrlBox is very easy to get started with. It offers an API for automation and you can customize and make requests from a very intuitive user interface. ![](/content/selenium-website-screenshot-alternatives/urlbox-thumb.webp) ### Onboarding *9/10* Onboarding with Urlbox is a breeze. Without much setup, we took the same screenshots from before. I simply pasted the URL, selected Full page and hit Render. With a well-documented REST API, they also provide a JavaScript SDK. Using their dashboard gives you the request options for both. With such an easy-to-use interface and an API that works out of the box, the development costs of using Urlbox are minimal. You spend a few minutes customizing your request and that’s it. If you want to automate the screenshot process, you’d have to wrap the API call around a script or another service. ### Accuracy and Quality *8/10* It is clear quality is taken seriously at Urlbox. Fonts are displayed correctly and the video from [nike.com](http://nike.com/) was correctly displayed. Without any extra configuration, we already got a picture that showed no scrollbars, no media controls and accepted cookies. They offer a Retina option for screenshots with 2x the resolution, allowing for pixel perfect images with sharper definition. The sticky navbar from [notion.so](http://notion.so/) behaved a bit funny. It did not display unless the Full Page Mode was set to native, but then the navbar displayed a little above the Hero, another try with the same setup on the next day returned a perfect render, subsequent requests had the layout problem again. ### Speed *8/10* Urlbox is not the fastest tool in the market. This is even more present when using the higher quality Retina option. Obviously, the bigger the image, the longer it takes. On our speed tests, Urlbox finished 2nd averaging 13.5 seconds per render. ### Customization *8/10* They offer a wide range of customization for your screenshots. You have options for Blocking, JavaScript injection, Screenshot Delay, CSS selectors to hide elements, HTTP Request with Proxy, custom headers, and even word highlighting. They do not offer an out of the box option for automation, so you would have to embed their API requests with another tool and they only provide a Node SDK, although you can call their REST API directly using HTTP requests. Everything you do on their user interface gives you the code to consume their API via HTTP request or the JSON for their SDK. ## Stillio *Great automation option for periodic screenshots.* As soon as you get to Stillio’s dashboard, you realize it is fully focused on automation. You add your web pages and set the capture frequency. You have options to download them automatically and via API. Unfortunately, there is no API for setting up your captures. ![](/content/selenium-website-screenshot-alternatives/stillio-thumb.webp) ### Onboarding *8/10* Easy enough to get started. All you have to do is add your web pages and set the frequency for the screenshots. The option to add multiple URLs on the same flow was a great plus and allowed me to get setup with my screenshots quickly, although it automatically set the capture time 1 minute apart. The option to add the webpage from a sitemap XML is great for monitoring ongoing changes on several different pages of the same site. Their API only allows you to access your images via HTTP requests. For developers who are looking for an API to call from their app, Stillio is not for you. ### Accuracy and Quality *7/10* Displays media correctly, hides cookies dialogue box, fonts are rendered correctly, and even the sticky navbar from [notion.so](http://notion.so/) was not a problem for them. There isn’t a lot of customization for quality here and their screen resolution is limited to a maximum width of 1920. Not great for simulating a 4k screen. If you are looking for high quality or a scaling factor, Stillio currently does not support that as it is focused on the automation side of things. Although not great on the image definition, out of the box it had no issues with any of the example websites and displayed them perfectly. ### Speed *4/10* As I tried to time how long it took for each screenshot to be rendered, Stillio’s focus on automation wouldn’t allow me to pinpoint exactly when a capture was started. I added multiple URLs for the pages I wanted and it automatically set each capture 1 minute apart. When I added a single page, it took less than a minute and a few page refreshes to see the first screenshot when selecting *now* for the starting at option. But again, single screenshots are not the focus on Stillio. On our speed tests, Stillio finished 4th averaging 55 seconds per render. ### Customization *6/10* Stillio is heavily focused on automation. They do offer an expert mode that allows you to use some CSS selectors to manipulate behaviour, but there isn’t much customization on the end result of the screenshot. You can manipulate the screenshot delay, a custom User Agent, and define cookies. They also don’t provide an API for setting up your environment, which complicates things when you want to embed them inside your app. Their focus is automation and simplicity. ## ScreenshotOne *Up to 3x pixel ratio and the fastest tool out of the box* Out of the box setup is not heavily focused on quality but their customization allows the user to take pixel-perfect images with higher resolution. Similar to Urlbox, they offer you an API and a playground to test your requests. Problems with the user interface layout might happen. ![](/content/selenium-website-screenshot-alternatives/screenshotone-thumb.webp) ### Onboarding *8/10* You’re asked on account creation if you would like to try out their “playground” first or go directly to the API key. From their playground, it is easy to get your first screenshot out, although some of the default options do not focus on image quality out of the box. Tweaking with the options takes a little bit of getting used to their interface, and I felt some of the options that were hidden under their collapsing menu could be classified as essentials, and some of them didn’t really feel like they belong in the section they were placed. A lack of information in some of the options might leave the less experienced screenshoting user a bit disoriented. Overall, it is easy enough to get your first screenshots out with ScreenshotOne, and consuming their API is also as simple as calling an HTTP request. ### Quality and Accuracy *6/10* For the ones that are really looking to zoom in the pictures, ScreenshotOne goes all the way up to 3x scale on resolution. Although their default options are not focused on image quality, you can still get high-resolution images by simply adjusting the viewport scale option. When it comes to accuracy, they had no problem with the media at [nike.com/gb](http://nike.com/gb), they block ads automatically, which may leave a few empty boxes in your render, and [notion.so](http://notion.so/) was not rendered fully, the bottom section of the page was cropped out. Their render of [adobe.com](http://adobe.com/) was not great and left all images out when trying a Full page screenshot, even when marking the Scroll option that supposedly forces render of lazy loaded images, although that wasn’t a problem with [theverge.com](http://theverge.com/). Unfortunately, although you can go crazy on the resolution, accuracy was not a strong point with ScreenshotOne. ### Speed *10/10* Although their accuracy was not at its best, they did make up for this with their speed. Of course, if you try the higher resolution options, the render time will increase, but their default options allowed them to be the fastest tool we tested. On our speed tests, ScreenshotOne finished 1st averaging 10 seconds per render. ### Customization *8/10* ScreenshotOne allows several tweaks to your render. From image output, there’s a generic quality selector from 0-100, corresponding to jpg compression, you can also customize caching, clipping, geolocation, delay, and even integrate with your OpenAI key with a prompt for their vision API. You can heavily customize the browser request before the screenshot is taken by modifying User Agent, Headers, and Cookies. Although they offer a lot of customization options, I wouldn’t say their user interface is in the best shape as of today. I had to zoom out in order to see the full menu due to layout issues. They do offer an API, and several SDKs for a smooth integration within your app. They support the following languages: Go, Ruby, JavaScript, Python, PHP, C#, and Java. The file encoding is up to you, after you get the result, but they do offer integration with S3 out of the box. ## ApiFlash *A simple API to get your screenshots* Focused on their API, with their user interface working as query builder, you can still check the results of a render on a new tab. ![](/content/selenium-website-screenshot-alternatives/apiflash-thumb.webp) ### Onboarding *9/10* ApiFlash sells itself as a simple service and that is really the case. Using their visual query builder to get your URL request ready is very easy, and the hover explanation of each option is also a great plus. Very easy onboarding with a free plan that has no date limit. Their user interface is not so friendly for non-developer users, and they offer no SDK as of today. ### Quality and Accuracy *6/10* The lazy loading on full page seems like a trend now. ApiFlash did well when loading the images on [adobe.com](http://adobe.com/), but the footer was left out. It also struggled to render images that were further down the longer pages, Nike, Notion, and TheVerge had images only on the top half of the render. Even when trying a capture with higher resolutions, or using their scale factor (for double resolution), the sharpness just wasn’t really there, it feels like there is some compression going on, even if you set quality to 100. ### Speed *6/10* Without any tweaking and using their out of the box setup, APIFlash felt a bit slow on the response time. On our speed tests, APIFlash finished 3rd averaging 20.2 seconds per render. ### Customization *6/10* They offer plenty of customization and even a direct integration with S3 to upload your captures. But they do not offer half of the customization options we have seen in the competitors. You have very little control over the image and no post-processing options. You can still make changes on Geolocation, JavaScript Injection, User-Agent, headers, cookies, and some more options related to the client used on the request. ## GoFullPage *Chrome extension that works with one click.* If you are looking for an easy alternative to get one-off screenshots on the go, GoFullPage is an extension that, once installed, captures your current Chrome tab fully by clicking on the extension. It is not for you if you are not using Chrome, or looking for customization. ### Onboarding *10/10* There really isn’t much to be said here. You install the extension with a few clicks, you click the extension, and see it scrolling down the page, as it captures it, and then you see your capture on a new tab. There is no sign-up, no plan choice, no customization. You hit one button, you get the screenshot. ### Quality and Accuracy *7/10* I believe this is very subjective. GoFullPage is not running on a server anywhere. It uses your machine to capture your Chrome tab. Hiding cookies banners, and any behaviour prior to the screenshot, is done by you. For that reason, it is very complicated to give it a rating, simply because I am not rating the service, I am rating my specific Chrome session on my specific machine and OS at the time of capture. Accuracy and reliability also get tricky here. I remember when I used Linux Mint, all the fonts looked a bit jagged, and if I were to capture with GoFullPage on that system, you can see where I am going, right? Still, on the session I had, I was actually very satisfied with the end result. The saved image looks much better than the preview, so keep that in mind. ### Customization *1/10* There isn’t much. This is an extension that captures your browser window as it is when clicked. If you don’t want the cookie banner, accept them or dismiss the dialogue. They do offer a premium plan with some extras but nothing related to changing the request and more focused on post-processing of the image. In all fairness, you would change your request using other tools since it’s your Chrome session. You can actually save the results as a .pdf and there’s an edit option that is only for premium users, as you would then have to sign up to export the results. GoFullPage is very specific for what it does and it is not trying to solve a different type of problem. ## Fireshot *A browser extension that goes beyond Chrome and gives you more control* Another easy alternative, very similar to GoFullPage, is Fireshot. It gives you some extra controls and supports Chrome, Firefox, Edge, and Safari. They offer an API that adds some sprinkles to how you use the extension, enabling partial automation of the flow, making editing and exporting the results a bit faster. However, it’s not something you can call remotely. It’s simply designed to automate the extension’s control on your browser. ### Onboarding *10/10* Very easy to get started. It is simple to install, no sign-up required, no plan choice. But *one* extra click here to select what type of capture you are taking. Once captured, saving the image or sending it via email is done very quickly. Exploring its different options and features was also very simple. ### Quality and Accuracy *6/10* Again, it relies more on your computer and behaviour before triggering the screenshot than anything else. The image definition is great and since this is not done online, they do not worry about image compression, so you get a very good result regarding pixel *presence.* Reliability and accuracy are the same as GoFullPage. I had issues with Fireshot on bigger pages. [theverge.com](http://theverge.com/) had some black boxes on the page, which I imagine is where the image is stitched together, and it captures as fast as it scrolls, so a few elements were still loading before they got captured. This issue would be fixed if you were to scroll the page back and forth before capturing or altering the scroll speed on the options. Maybe tweaking with some options would help improve the quality, but the result out of the box wasn’t great. ### Customization *6/10* Of course, not an automation system for screenshots, they do offer extras on top of simply taking a screenshot of your Chrome tab. You can set a list of URLs to capture but these are going to open on your Chrome and run the capture process. You can choose to capture a full page, a visible viewport, or a selection of the page, as you would with Snipping Tool or Firefox screenshot tool. On the result page, you can select to simply copy the image to your clipboard so you can Ctrl+V it away, directly attach it to a blank email on Gmail, or download it as an image or .pdf. Before capturing, you can tweak a few options on the extension and even alter the scroll speed and file format. Comparing it against GoFullPage, it would be a 10/10 for customization, but today we’re not only evaluating browser extensions. ## Playwright *A browser automation tool focused on tests with support for .NET, Python, JS and Java* Playwright is an end-to-end testing tool. It can also be used to capture some screenshots, but without a user interface. Its code felt easier to implement than Selenium, and it had less problem with media. Some websites will block headless browsers and that would incur extra work in avoiding their efforts. I wasn’t able to get to [adobe.com](http://adobe.com/) or [theverge.com](http://theverge.com). Same as Selenium, for each problem, you code to fix it. ### Onboarding *7/10* The documentation is very clear and the first screenshot came out in a few minutes, but Playwright is an automation tool made for writing test scripts and if you want to use it as a screenshotting tool you are going to put in some work. The onboarding costs would depend on a lot of factors, and you will have to write every functionality or customization you want. You’ll need specific selectors for the cookies, you’ll need specific behaviour automation to get lazy loading in, etc. On top of that, if you want to use Playwright remotely or as a separate service, you would have to fully create the service, API endpoints and storage. Although it is a developer option, Playwright’s setup is easy enough and simple screenshots can be taken easily. ### Quality and Accuracy *8/10* You are in control of the setup here. You can change Scale Factors to get better resolutions or change some of the many options the screenshot function accepts as arguments. Accuracy also depends on the implementation you take here. You can add evaluations to ensure all images and fonts are correctly loaded or you can add timeouts to wait for complex animations to complete. Using it out of the box we had to fix the cookie banners showing on the renders and images on the bottom of the fullpages were not loaded properly. You would have to simulate some user behavior to ensure lazy loads work. Regardless of the out of the box lack of accuracy, the resolution of the images was great even on a 1x scale. Making it a 10/10 depends on how long you want to improve the code you are running. ### Speed *?/10* Another point that you are in control of. It felt surprisingly fast to use Playwright without much configuration. I was running the same Ubuntu VM on Oracle’s free tier from Selenium and still averaged around 11 seconds for the screenshot to be saved. Add this to how long it would take to send the file to your favourite storage and get the url for the image back and there’s your speed. Of course, I did this directly via ssh. Wrapping the service around an API and considering security measures would play an impact on the end speed of service. You could make this better by using a more robust machine with a setup focused on speed or you can opt for better quality output that will increase your processing. For that reason, it wouldn’t be fair to compare Playwright’s speed of service with the Full services we saw here. ### Customization *10/10* This is where the browser automation tools shine. Differently than Selenium, Playwright’s screenshot function has many options regarding quality, output and even disable CSS animations - Capturing [notion.so](http://notion.so) page would greatly benefit from this. You can customize everything from the request to the output. Once you have the image buffer, you can really decide what to do with it, you can add any storage service you want, send it via email or whatever else you need. I felt like I had full control over the implementation if wanted, but still having a lot of default options is also a great option to not worry so much about details. ## Puppeteer *Browser automation focused on JS* Puppeteer It works with only Chrome or Firefox, it provides proprietary support only for JS, although you have community driven libraries in other languages. Similarly to other automation tools, you are running a headless browser that will get blocked by some pages and you’ll need to work around this obstacle. [Adobe.com](http://Adobe.com) and [Theverge.com](http://Theverge.com) both blocked our attempts. ### Onboarding *7/10* With good enough documentation and a much simpler set of features than Playwright, getting started with Puppeteer was easy enough, and the only problem I had was having to customize it to run with Chromium rather than the native Chrome option, since I ran it on my Ubuntu VM on an ARM processor. Getting my first screenshot from there was very quick. Since this is a developer-focused tool with a focus on end-to-end tests, the implementation cost to set your own screenshotting service here would depend fully on how complex your system needs to be. Bear in mind, Puppeteer is simply the headless browser automation tool; it does not offer you an API for remote access, storage, or anything similar. You are in charge here. ### Quality and Accuracy *7/10* Being in control is great, but I am measuring the result, out of the box, without tweaking for quality. The media on Nike’s website was displayed correctly and no scrollbars were visible. But several issues regarding accuracy are visible here. You do have many options to change; for example, the quality option affects how compressed JPG and WebP images are—the lower the quality value, the higher the compression. When setting your device viewport, you can also set a device scale factor for higher pixel density resulting in better definition. The problem with lazy loading is still present and requires further implementation in the capture algorithm to fix. Any image on the bottom half of the window for full page render is simply not loaded. If you are developing for constant screenshots of a single page, it’s worth spending some time ensuring you get a perfect result, but keep in mind, more pages means more work. ### Speed *?/10* Also heavily dependent on the overall implementation. It is quick enough to command the browser to navigate to a certain page, take a screenshot and save it to a path with the default configurations on a 1080p viewport—around 7 seconds. But then again, this is only how long it took for Puppeteer to do its job; if you build an API around it, make changes to the quality and depending on the setup you’re running, the speed will get impacted. For that reason, just like with Playwright, we are not comparing Puppeteer’s speed with the API services we have. ### Customization *10/10* As you’d expect, developer focused tools allow a lot of control. Although it has fewer features than Playwright, Puppeteer’s customization is still nothing to be ashamed of. It allows you to customize from file format output, image clipping directly from the algorithm and even use its test features, such as evaluate and assert, to guide its behaviour ensuring you have a great page render before you capture the screenshot. You can also customize your request’s headers, cookies, what to do with the output after the capture, and elements to omit. You can customize pretty much everything, and even their Screenshot interface allows many arguments to shape the capture. ## Conclusion It was great to test all these different tools. As I am a software developer myself, I can’t avoid getting dragged closer to the tools made for developers. For a fully customized option, I really enjoyed working with Playwright. If I am choosing an all-in-one solution, Stillio and Urlbox are great options with a few different objectives. Urlbox allows me to wrap their API and make pretty much any use of it with a great level of customization, similar to what I have with Playwright and Puppeteer without the fuss of hosting and writing a full API. Stillio focuses on the periodically taken screenshots and automation out of the box. Both have great quality and differ in image definition and accuracy. If what you need is a one-off screenshot, I hardly recommend going with Snipping Tool or a native screenshot from the OS, simply because GoFullPage allows for great results of full-page renders with just one click. There were other tools I really wanted to test but couldn’t. Either because of a “Contact our sales team” sign-up wall or simply not working when I did the tests. Those were: ScreenshotAPI, PageVault, PageFreezer, and Pikwy. I hope I was able to help you in your decision of choosing the best tool for your needs by testing them all so you don’t have to. Now it is all about making a choice and getting it to work. ### Comparison Here are all the captures if you want to have a peek on each of the results I got.

You can use that information to create targeted materials that address your target market's problems. Moreover, understanding your target market can help you identify the best channels for reaching and engaging with ideal buyers. For example, if you know your target market is primarily young entrepreneurs, you might focus your marketing efforts on platforms like LinkedIn or [Twitter](https://urlbox.com/automated-screenshots/twitter.md). The best way to define your target market is by running surveys or simply looking over your competitors' social profiles and reviews. One of the best ways to achieve this is by using a [brand monitoring tool](https://urlbox.com/brand-monitoring-tools.md) that can help you get a clear idea of what types of people use a product like yours and what they expect from it. ## Develop a marketing plan Once you have a target audience in mind, it's time to create the product launch strategy. ![image2](/content/successful-product-launch/image2.png) A marketing plan for a successful product launch should be a comprehensive and detailed plan that outlines the following: - Target market -: A clear definition of the target audience for the product. This includes demographic information, such as age, gender, location, and income, as well as psychographic information, such as interests, values, and attitudes. - Marketing objectives - The marketing plan aims to achieve specific, measurable, achievable, relevant, and time-bound (SMART) goals. These may include increasing brand awareness or driving a certain number of sales or sign-ups. - Marketing strategy - A high-level plan for achieving the marketing objectives. This strategy should include social media marketing, email marketing, content marketing, or advertising. - Marketing tactics - Specific actions or activities that will be taken to execute the marketing strategy. These include creating social media posts, email newsletters, or buying ads. - Budget and resources - A detailed plan for how much money and other resources will be allocated to each marketing tactic. This may include information on the cost of advertising, the time and effort required to execute each tactic, and any external resources that will be needed, such as design or development services. - Measurement and evaluation - A plan for tracking and measuring the marketing plan's success. This may include metrics such as website traffic, social media engagement, or customer sentiment via [brand monitoring](https://urlbox.com/brand-monitoring.md). You should not be too concerned over how good or bad your marketing plan is if it's the first time you launch a product. What's important is that you stick with it until you have concrete data that it might not work. Many launches fail because the people behind the product do not follow a strategy but rather do things randomly. The best way to start implementing your marketing plan is by generating buzz. ## Build buzz Buzz helps you build anticipation and excitement among potential customers before your product launches. All this can create a sense of urgency and increase demand. ![image7](/content/successful-product-launch/image7.png) It also helps you improve visibility so you can attract more potential customers and increase the reach of your marketing efforts. Building buzz is a tedious task, not to mention that it might not work at all. But it's one of the best ways to ensure you get as many leads as possible during your launch. You can use various platforms and methods to let people know about your new product, like: - posting on Reddit - presenting your product on Slack groups - networking with people in your niche to amplify your reach - taking part in conferences or appearing in videos or podcasts. Bottom line, generating buzz around your product before the launch can be a valuable way to increase anticipation, demand, visibility, and credibility, which can all contribute to the success of your product launch. So make sure you do your best to generate as much buzz as possible. ## Create a landing page Now that people know you plan to launch a new product, it's time to create a landing page. This is where you'll go in-depth about how your product can solve the existing problems of your target market. ![image5](/content/successful-product-launch/image5.png) An excellent landing page clearly shows the benefits and features of your product and explains why it's a better alternative to existing solutions. You should also include a call-to-action asking people to register to your launch email list. It can be challenging to create a landing page if you have never done it before, so you should ask for the help of a professional. But if you plan on launching any new products in the future, you might want to learn this skill yourself. A great way to get inspired is by keeping a swipe file of pages that caught your eye. Here's how easy it is to start [creating your own swipe file with Google Sheets and Zapier](https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier.md). Now that you have your landing page published, you need to set up the infrastructure behind the product launch, which revolves around email marketing. ## Build an email list Most successful product launches are driven by email marketing. This is how businesses keep in touch with interested people about the launch of their new product and how fast it will be live. ![image4](/content/successful-product-launch/image4.png) Email campaigns are designed to create buzz before the product launch. The goal is to build anticipation for the launch and encourage people to take action and purchase the product right as it becomes available. You can use a variety of tactics, such as sending teaser emails to create curiosity, providing exclusive discounts and promotions to early adopters, or hosting giveaways. Additionally, email campaigns can be used to educate customers about the product, its features, and why they should purchase it. Using email marketing to drive your product launch is the best way to ensure your target audience is aware of the launch and has the opportunity to purchase the product. You can use any tool to start building your email list and automation. Among the most popular ones are Mailchimp, Klavyio, or Constant Contact. As a matter of fact, it doesn't matter what software you use. What matters most is capturing interested people's emails and constantly teasing them until the launch. With the infrastructure in place, it's time to generate visits to your landing page, and one of the best ways to do this is by using social media. ## Use social media to promote your product launch Social media is a powerful tool to spread the word about your product launch and reach your target audience. Posting development updates with images or videos on different platforms can boost anticipation and interest in your product. ![image3](/content/successful-product-launch/image3.png) Make sure to display your landing page URL and a short value proposition on all your profile pages. Since social media posts can become viral, new people need to understand who you are and register for the launch. Another way to generate buzz with social media is by using sponsored ads to target the exact audience you want to reach. Depending on your pre-launch budget, this might not be the best way to go, as it comes with high costs. But if you have the budget, be sure your sponsored posts are well-crafted and targeted toward the right audience. Finally, you can use influencer marketing to spread the word about your product launch. Reach out to influential people in your industry and ask them to share their thoughts about your product launch. Chances are you already expanded your network, so this should not be too difficult. Social media can be a great way to boost your reach and increase your chances of a successful launch. Now that you have warmed up your audience, it's time for the big event. ## Launch The actual launch of a product is way easier than you might expect. ![image1](/content/successful-product-launch/image1.png) You already have an audience waiting for the day of the launch and the infrastructure in place, so all you have to do is announce the launch on all mediums: - Post on social media - Keep your audience engaged and announce your launch on all your social media pages. You can also include a giveaway or a unique promo code for people that purchase your product the day it launches. - Email your list - You should send an email a day before the launch and another one when the launch happens. Chances are people will not see this email instantly, so you have to be patient. Make sure you mention any promos or giveaways. - Reach out to your network - Remember to notify your network that you are about to launch your product. It's better to send each person a customized message via DM or email. - Run paid ads - It's essential to get as many new people as possible interested in your product right from launch. One of the fastest ways to boost your reach is by running sponsored ads on social media platforms. The goal of the launch is to get as many new users as possible, all while you increase your product's visibility. The launch can also help you understand what people think of your product, which will be invaluable for further development. Data stands at the core of business development, so you should collect and store as much of it as possible. Data can be broken down into two major categories: - Quantitative data - includes number-based data like website visits, signups, conversion rates, etc. - Qualitative data - includes data that can not be quantified, like what people think about your brand, what they like, and what they would improve. It's easy to generate and analyze quantitative data using tools like Mixpanel or GA4. But things get complicated regarding qualitative data, as you will have to track, archive, and explore [online brand mentions](https://urlbox.com/brand-monitoring.md) across various channels. ## Track and store brand mentions Tracking online mentions of your product or brand after the launch can be an important way to identify opportunities to engage with your audience. This can be done either manually or by using a [brand monitoring tool](https://urlbox.com/brand-monitoring-tools.md). ![image6](/content/successful-product-launch/image6.png) You can use qualitative data to address any issues or concerns your customers might have, which can help you build trust and loyalty among your user base. This data can also help you identify any areas for improvement or areas where your product is particularly successful. If you decide to use a tool, then you will be able to quickly identify negative feedback or reviews about your product, which can help you mitigate any potential damage to your brand and reputation. Launching a flawless product is impossible, but people will keep using it as long as you improve and fix issues. Last but not least, you can use qualitative data to measure the success of your product launch. This can help you understand how well your marketing efforts are working and make the necessary adjustments. ## What Makes a Product Launch Successful A product launch is successful if it helps you reach your goal, like getting 100 users on the first day, selling 50 items in the first hour, or boosting your email list by 200 people. Success is based on your business model and what your product does, so it's only natural it looks different for each organization. Now that you have launched your product, you should look back and analyze everything you did to get even better.

Source: https://urlbox.com/summarize-articles-with-chatgpt Last updated: 2023-07-27 --- People always complain of never having enough time for reading. And with so much information being shared every day, it’s getting increasingly harder to keep up with everything. Fortunately, LLMs such as ChatGPT come to the rescue. These can be used to extract the essence of web pages, articles, and even [PDFs](https://urlbox.com/automated-screenshots/convert-webpage-to-pdf.md), so we can ingest more information faster than ever. In this article, we’ll cover the best ways to summarize articles and PDFs with ChatGPT, going over the pros and cons of each method in terms of accuracy and costs. ## How to quickly summarize an article with ChatGPT Here’s the fastest way to summarize almost any article with ChatGPT: 1. Copy the text of the article (or the URL if you use ChatGPT Plus). 2. Log in to chat.open.ai and create a new chat (select Model > Web Browsing for ChatGPT Plus customers). 3. Paste the text (or URL for ChatGPT Plus members) and ask ChatGPT to “summarize it” by typing that right after the text. Here’s how it looks: ![image1](/content/summarize-articles-with-chatgpt/image1.png) You can always change the prompt to suit your needs. For example, you can ask ChatGPT for an “ELI5 summary”, which will oversimply the text, or even write a “shorter summary with a bullet list that starts with emojis”. Regardless of how you want the summary to sound like, you have to keep in mind that ChatGPT has two main limitations: - The summary might be incorrect - LLMs are notorious for the way they tend to hallucinate, meaning they can write plausible-sounding text that is actually completely wrong. You should keep this in mind and always read the article to double-check that the output is correct. - There is a max token limit - The free version of ChatGPT has a limit of around 3000 words (4,096 [tokens](https://platform.openai.com/tokenizer)), while ChatGTP Plus’ limit is double. This includes everything you have typed in the chat before asking for the summary, as well as ChatGPT’s responses, so make sure you always create a new Chat before you ask for a summary. It’s also important to note that some models available in the OpenAI playground have a higher token limit (such as the gpt-3.5-turbo-16k, which has a 16,384 token limit). ## How to summarize a large PDF document with ChatGPT Online articles are usually no longer than 2500 words, which means that ChatGPT can easily summarize them in less than 500 words. On the other hand, PDF files can easily surpass the maximum number of tokens, making the whole process a little more difficult. Even so, here are two methods to summarize any PDF file, regardless of its size. ### Use the text chunking strategy This method involves using a chunking strategy with ChatGPT. Here’s what you have to do: 1. Manually divide the text from the PDF document into smaller, manageable chunks that fit within ChatGPT's maximum message limit. 2. Input each chunk separately into the ChatGPT interface. 3. Ask ChatGPT to summarize each chunk. 4. Combine the summaries of each chunk to get a preliminary summary of the document. 5. Input the preliminary summary into ChatGPT and ask it to summarize it again to get the final summary. Even though this might seem tedious, it’s the best way to summarize a PDF using the free version of ChatGPT. You should also bear in mind that the output might not be completely accurate. ### Use a plugin The approach involves using the AI PDF plugin (or any other PDF plugin) within the ChatGPT interface. This method is only available to ChatGPT Plus subscribers, but it’s one of the best ways to summarize PDFs using ChatGPT’s UI. ![image2](/content/summarize-articles-with-chatgpt/image2.png) Here are the steps: 1. Open ChatGPT, navigate to the settings by selecting your name in the bottom left, then choose “Settings & Beta”. 2. Inside the settings menu, click on “Beta features” and toggle on the “Plugins”. 3. Open a new chat, select GPT-4, and click on the “Plugins” button. 4. Now open the Plugin store, search for Ai PDF, and install it. 5. Provide the URL of the PDF document to ChatGPT and ask it to summarize it. Plugins can handle the entire process, from extracting the text to generating the summary, making it a great option for any PDF length. We have tried the plugin with documents of up to 300 pages, and it was always able to correctly summarize the contents and answer any questions about the PDF. ## Best ways to summarize online articles with GPT API So far, we’ve explored various methods to summarize text using the ChatGPT UI. Now, let's shift gears and go over the best ways to summarize online articles with the GPT API. ### Use Python You should only follow this method if you're comfortable with Python and want a high degree of customization. It involves using the programming language in conjunction with the GPT API, as detailed in this [tutorial](https://www.allabtai.com/how-to-summarize-a-large-text-with-gpt-3/). One thing to keep in mind is the cost associated with this method. GPT models charge per token, and costs can quickly add up depending on the size of the text you're summarizing. Not to mention that you must use the GPT-4 model if you want the highest possible accuracy, which is 20 times more expensive than GPT-3.5-Turbo. ### Text chunking and conversion with Url2Text This approach breaks down the content into smaller, more manageable pieces, making it easier for the model to process and summarize. The real game-changer here is [Url2Text](https://url2text.com/), a tool that can extract the body text of a web page and convert it to markdown. Why is this important? Well, by converting to markdown and stripping unnecessary HTML tags, inline CSS, and JS scripts, you can significantly reduce token usage. This will lead to cost savings, especially when summarizing complex web pages. You should also keep in mind that text chunking requires a bit of finesse. You need to carefully chunk the text to maintain context across each piece. If done correctly, this can lead to high-quality summaries. But remember, the accuracy of the summary largely depends on the quality of the chunking and conversion process. ### Combine the GPT API with extractive summarization algorithms This method is a hybrid approach that combines the power of the GPT API with the efficiency of extractive summarization. The first step involves using an extractive summarization algorithm. This type of algorithm works by pinpointing the key sentences or phrases in the text - the ones that capture the essence of the content. It's like mining for gold, where the gold nuggets are the most essential pieces of information in your text. Once you've identified these key elements, the next step is to feed these sentences into the GPT API. The GPT model then takes these inputs and generates a coherent summary. It's like taking the gold nuggets you've mined and melting them into a gold bar. One of the key advantages of this method is its cost-effectiveness, mainly because you're feeding the GPT model with the essence of the text rather than the entire body. But like all the previous methods, the quality of the output depends on the quality of the input. The accuracy of the summary can depend on the quality of the extractive summarization and the GPT model's ability to generate a coherent summary from the provided sentences. ### Use the GPT API with post-processing Last but not least, you can use the GPT API with a post-processing step. This method is a two-step process that first generates preliminary summaries and then combines and refines them into a polished version. The first step involves using the GPT API to generate a preliminary summary. This is where the GPT model does its magic, taking your text and condensing it into a shorter version that captures the main points. Once you have your preliminary summary, it's time for the second step: post-processing. This is where you refine the summary, removing redundant information, ensuring coherence, and checking for grammatical correctness. One of the key benefits of this method is the potential for high accuracy. By refining the summary, you can improve its quality and ensure it accurately represents the original text, but this process will surely increase the overall token usage and cost. ## What is the best way to summarize an article with ChatGPT? The best way to summarize an article with ChatGPT largely depends on the type and size of the document, your budget, and how accurate you want the summary to be. If you're dealing with smaller articles and prefer a straightforward approach, copy-pasting text into the ChatGPT UI might be best. You should use the AI PDF plugin or the GPT API in conjunction with other tools for larger documents. ## FAQs ### Can GPT 4 summarize a webpage? Yes, GPT-4 can summarize a webpage. It can process the text content of the webpage and generate a concise summary, although the effectiveness can depend on the complexity and length of the original content. ### Can you use ChatGPT to summarize articles? Of course, you can use ChatGPT to summarize articles. Simply input the text of the article, or URL, into the ChatGPT interface and the model will generate a concise summary of the main points. ### How do I get ChatGPT to summarize a PDF? To get ChatGPT to summarize a PDF, you can manually copy and paste the text into the ChatGPT interface. For larger PDFs, you can use the text chunking strategy or a plugin. --- # How To Create a Swipe File with Google Sheets and Zapier > Learn how to create your own swipe file using no-code tools and share it with your followers, employees, or clients. Source: https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier Last updated: 2025-03-21 --- A swipe file is a list of valuable ideas and insights to draw from when you feel like you hit a roadblock. Everyone feels stuck from time to time, so having a collection of materials you can get inspiration from can be a lifesaver, especially when your deadline is closing in. Swipe files are mainly used by marketers, although they can be an excellent asset for designers and developers alike. In this article, you'll learn how to create your own swipe file using no-code tools and share it with your followers, employees, or clients. ## Why build your own Swipe File If you're a marketer, designer, or indie developer, chances are you've experienced creator's block. Often, you find yourself looking at a task the same way as you always did, thus failing to consider other outside-the-box options. Checking your swipe file is a great way to shift your approach and come up with fresh ideas and solutions. Here are the most common swipe file examples by industry. ### Marketing Swipe Files Creating a marketing campaign is a tedious process that can inevitably induce a mental block. This can happen to everyone, regardless of how experienced they are. People have created swipe files since the early 1920s. Back then, they cut out pieces of magazines and newspapers and kept them in an album. Today, all you have to do is take a screenshot. It can be anything that sparked your interest, like a landing page, headline, ad, or even Twitter post. You can then save that screenshot locally or upload it to your Google Drive or Dropbox. You can also automate this process, as I'll share in a minute. But before that, here are the most common marketing swipe file categories. - *Headline Swipe File* - This kind of swipe file contains screenshots of various ads and articles and is focused on headlines - *Copywriting Swipe File* - This type of swipe file features screenshots of sales letters and landing pages - *Email Swipe File* - This swipe file consists of emails that feature great copy or have a great template design - *Ads Swipe File* - This swipe file is mainly used by PPC marketers to save screenshots of various display ads - *Twitter Swipe File* - This swipe file is used by social media specialists to [screenshot tweets](https://urlbox.com/automated-screenshots/twitter.md) and threads they find interesting. Besides marketers, other industry experts keep swipe files to overcome the creator's block. ### Web Design and Development Swipe Files Designers and web developers alike keep swipe files. These are mainly focused on the visual part of a website or platform and less on the actual copy. These swipe files are usually focused on the most important pages of a website or app: - *Landing Pages Swipe File* - This type of swipe file consists of [full page screenshots](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md) of landing pages - *Dashboards Swipe File* - This type of swipe file features screenshots of various dashboards and elements - *Pricing Page Swipe File* - Mostly used by designers, this type of swipe file features screenshots of pricing pages with a focus on how the information is displayed. Keeping a swipe file can help when you get stuck and need inspiration. But you can also use it to keep track of trends and even your competitors. ## How to build a swipe file with Urlbox and Zapier The fastest and easiest way to start your own swipe file is by using Zapier and a [website screenshot generator](https://urlbox.com/screenshot-api.md). Note: Zapier connects to thousands of apps, so the possibilities are virtually limitless. ### Create a Landing Page Swipe File with Google Sheets and Zapier One of the most common types of swipe files is a Landing Page swipe file. You can start your own by connecting Google Sheets with Urlbox and Google Drive through Zapier. Before you start, you'll need to sign up for Urlbox and Zapier. You'll also need a Google account. #### Step 1. Create a Urlbox account Signing up to Urlbox is extremely simple. Simply go to the [pricing page](https://urlbox.com/pricing.md) and select a plan that suits your needs. Alternatively, you can directly sign up for a [7-day free trial](https://urlbox.com/pricing.md). The cheapest plan goes for $19 per month and lets you capture up to 2,000 screenshots each month. #### Step 2. Sign up for Zapier Now you have to register a Zapier account. You can do so by following this [link](https://zapier.com/sign-up). Remember that you will need the premium Zapier subscription for this automation, which involves three steps. Their cheapest plan is $19.99 per month, but if this is your first time registering, you'll get a 7-day free trial. #### Step 3. Create a Google Sheet With the accounts ready, you'll need to create your swipe file directory as a Google Sheets document. Note: I always create a new folder for each swipe file I plan on building. This helps me keep things organized and easily accessible. For this example, I have created a new folder called Landing Page Swipe File. Then I simply right-clicked and created a new Google Sheets document. You can copy the spreadsheet by clicking [here](https://docs.google.com/spreadsheets/d/1ofdaO1Zep8yfRYx6IsUk-1bMwmIlRm4DIvvurnm0GFI/copy). This document should have a single column titled "Landing Page URL." As the name suggests, this is where you will paste the URL of the landing page you want to screenshot and save. #### Step 4. Create the Zap Zaps are the automations you are going to set up with Zapier. Just log in to your account and click on Zaps in the right menu to create one. Alternatively, you can click on the big "+ Create Zap" orange button. #### Step 5. Configure the trigger This will take you to a new page where you must set up the trigger of this automation. Type in sheets and select Google Sheets from the list. ![image8](/content/swipe-file-with-google-sheets-zapier/image8.png) Now select "New Spreadsheet Row" as the triggering event. This will ensure that each time you add a new URL to the spreadsheet, Urlbox will take a screenshot of it. ![image3](/content/swipe-file-with-google-sheets-zapier/image3.png) Pick the Google Account you used to create the spreadsheet and log into it. Finally, select the spreadsheet you just created from the dropdown list (it should be the first one in the list called "Landing Page Swipe File"). Now select the Worksheet. This is the name of the tab you are going to use, and it should be "Sheet1". Click "Continue" and test your trigger. Since the spreadsheet is empty, you might need to add a row to it for Zapier to check if the trigger is working. ![image5](/content/swipe-file-with-google-sheets-zapier/image5.png) That's it; the first step is done. Now you need to set up an Action. #### Step 6. Configure the action The action simply tells Zapier what should be done when a new row has been added to the spreadsheet. In this case, we want to take a full-page screenshot of a URL that has been pasted inside the spreadsheet. Type "Urlbox" in the search field and select it. ![image10](/content/swipe-file-with-google-sheets-zapier/image10.png) Next, you'll want to select "Generate Screenshot From URL" as the Event. ![image2](/content/swipe-file-with-google-sheets-zapier/image2.png) In the next step, you will have to connect your Urlbox account to Zapier. Just follow the prompts. Right after that, you must configure the action's parameters. This tells Zapier what data to send to Urlbox. Click on the "Url" field and select the "Landing Page URL" column. ![image11](/content/swipe-file-with-google-sheets-zapier/image11.png) You can change the screenshot's output file format to anything you like. I prefer to stick with PDF for full-page screenshots. Next, you must scroll to the "Full Page" field and select "True". This will make sure that Urlbox will capture the whole landing page. ![image4](/content/swipe-file-with-google-sheets-zapier/image4.png) Note: An extra step would be to set the "Wait Until" field to "All Requests Finished." This will make sure the page is fully loaded before Urlbox screenshots it. ![image6](/content/swipe-file-with-google-sheets-zapier/image6.png) To test if the action is working, you must have the correct URL inside your spreadsheet. You may get an error when testing this Zap. To fix it, you will have to go to the "New Spreadsheet Row in Google Sheets" Trigger, click on the "Spreadsheet Row A," then click on "Load More," then select "Spreadsheet Row B." This will tell Zapier that you want to use the second row to test the Zap. ![image1](/content/swipe-file-with-google-sheets-zapier/image1.png) If you've followed all steps, then you should see something like this: ![image7](/content/swipe-file-with-google-sheets-zapier/image7.png) You can check the screenshot by pasting the screenshotUrl link into your browser. Now that you configured the Zap to take a screenshot for each new URL you add to your swipe file document, and it's time to push this screenshot to the Google Drive folder. #### Step 7. Save the screenshots to Google Drive Click on the small plus icon at the bottom of the screen to create a new action. This time you will select Google Drive as the app. Select "Upload File" as the event and click "Continue." Select your account and continue (you might need to authorize Zapier to access your Google Drive). Now you'll have to select your Drive and Folder. Make sure you use the same folder where your Google Sheet is located. It should be called "Landing Page Swipe File." Click on the "File" field, select "Generate Screenshot From URL in Urlbox," click on "Show all options" and select "Screenshot URL". ![image9](/content/swipe-file-with-google-sheets-zapier/image9.png) That's it. Now click continue and test your Zap. You'll see a new document in your Google Drive folder in a few seconds. This document will be a PDF version of the landing page you want to save. Last but not least, click on "Publish." Congratulations, you just started your first swipe file. #### Step 8. Share the swipe file Since you are hosting your swipe file on Google Drive, you can share that folder with anyone. Moreover, you can even share the spreadsheet with your team so they can contribute to the swipe file. As mentioned before, you can use any other cloud hosting service, like Dropbox, Onedrive, pCloud, etc. ## Conclusion A swipe file is a collection of valuable ideas, insights, and inspiration to draw from when you feel like you hit a roadblock. It can be a lifesaver when your deadline is closing in. And the sooner you start your first swipe file, the more examples it will include. You can create any type of swipe file with Google Sheets, Zapier, and Urlbox. But you can also switch Google Sheets with Airtable or even a completely different app, like Twitter. All you need to do is pass a URL to the Urlbox Zapier "Action", which will automatically capture a screenshot and generate a link. Need some inspiration on things to swipe?

Source: https://urlbox.com/testing-screen-sizes Last updated: 2025-06-09 --- In the age of smartphones, ensuring your website looks and functions seamlessly across devices has become increasingly important. A responsive and adaptable design can significantly enhance user experience, leading to better engagement and conversions. In this article, we'll explore why testing your website on different screen sizes is critical for user experience and provide insights on how to test your site on a diverse range of devices effectively. ### What is User Experience (UX)? User experience (UX) refers to a user's overall experience when interacting with your website. UX encompasses all user interaction aspects, including usability, functionality, design, accessibility, and emotions elicited throughout the process. The main goal of user experience is to create a seamless, efficient, and enjoyable experience that meets the user's needs and expectations. A well-designed website can increase user satisfaction and engagement rates, improve customer loyalty, and even boost conversions and revenue. In contrast, a poor user experience can result in frustration and lower engagement, hurting your business. ## What is responsive website testing? Responsive website testing evaluates and ensures a website works as expected and displays optimally across various devices and screen sizes. As users access websites from multiple devices, including desktops, laptops, tablets, and smartphones, a website must seamlessly adapt to these different environments. Responsive website testing involves checking the following aspects: - Layout and design: Ensuring the website's design elements, such as images, text, and navigation, adapt and reposition themselves properly according to the screen size and device orientation. - Functionality: Verifying that all features and functionalities of the website, including buttons, links, forms, and media playback, work smoothly and consistently across different devices. - User experience: Assessing the website's overall usability, including readability, navigation, and loading times, ensures users have a positive experience regardless of their browsing device. Responsive website testing can be performed using various tools and techniques, including device emulators, real device testing, and automated testing tools. A critical aspect of web development is to deliver a consistent and enjoyable user experience, leading to higher user engagement, better conversion rates, and improved overall website performance. ## Why you should test your website on different screen sizes and devices People browse the Internet from various devices such as phones, laptops and desktops, tablets, and even TVs, which means your website should be able to adapt to virtually any screen size, from 5-inch phone screens to 40-inch TVs. That's why it's important to constantly test how your website loads on different screen sizes and devices. Testing can also help you discover possible bugs before they become significant problems. Using an [AI tool for testing](https://momentic.ai/) at this stage can significantly streamline how those bugs are identified across breakpoints and devices. Instead of manually inspecting every screen variation, AI can simulate user interactions and flag layout or usability issues proactively. This enables faster iterations and higher confidence before deployment. It’s especially useful for content-heavy or frequently updated sites that require ongoing visual checks. Making sure your website renders properly will not only provide a great user experience but can also help you rank higher on search engines, boost conversions and sales and help you maintain a [professional brand image](https://urlbox.com/brand-monitoring.md). ### Increase user experience Testing your website on different screen sizes and devices allows you to identify and fix any design, layout, or functionality issues that may hinder a user's experience. A well-optimized website provides a smooth, user-friendly experience across all devices, increasing user satisfaction, engagement, and the likelihood of users returning to your site. ### Improve SEO Google has adopted a mobile-first approach, favoring websites optimized for mobile devices in its search rankings. By testing your website on different screen sizes, you can ensure that it is fully responsive and meets Google's standards, leading to increased visibility in search results. Furthermore, a well-optimized website helps decrease bounce rates, as users are more likely to stay on a site that offers a seamless experience, which can improve your search engine rankings. ### Boost conversions and sales A website optimized for different screen sizes makes it easy for users to navigate and complete desired actions, such as making a purchase or filling out a contact form. Moreover, displaying information in an easy-to-read manner and ensuring that essential features function smoothly on all devices can directly impact conversions and sales, ultimately increasing your revenue. ### Ensure a consistent brand image Testing your website on various screen sizes and devices helps maintain a consistent brand image across all platforms. A cohesive design and user experience on every device showcase your brand's professionalism and commitment to quality, reinforcing trust and credibility in the minds of your users. Consistency also helps build brand recognition, ensuring your website leaves a lasting impression on your audience. ## How Testing on Different Screen Sizes Works Ensuring a positive user experience across various devices requires testing your website on multiple screen sizes. This process helps you identify and address design, layout, or functionality issues affecting usability. Several approaches can be used for this testing, such as device emulation, screenshot-based testing, and real device testing. ### Device emulation and testing tools Device emulation and testing tools enable you to simulate how your website loads and displays on different devices and screen sizes. Not many of these tools allow you to automate the testing process, so you'll have to manually check your website after every update. These tools can be pricier than other alternatives, but they may work better for complex websites that require more extensive testing to ensure optimal user experience. ### Screenshot based testing Screenshot-based testing helps ensure your website is free of bugs and visual inconsistencies across different devices. This method lets you keep an archive of your website's appearance, enabling you to track changes and correlate any issues that may arise over time. In addition, screenshot-based testing is the cheapest and fastest option to implement, as you can set it up and let it run automatically. One such tool that offers this service is Urlbox, which provides an [easy-to-use API](https://urlbox.com/screenshot-api.md) for capturing screenshots of your website on various devices. ### Real device testing Real device testing involves testing your website on actual devices, such as smartphones and tablets, to ensure proper functioning and appearance. This method is less preferred due to the need for a wide range of devices and the associated costs. This type of testing is most suitable for apps built for specific devices or operating systems, such as iPhones or Android phones. And while you can automate real device testing, it can be expensive and prone to errors due to the physical limitations and varying conditions of the devices being used. ## 5 Tools for Testing Your Website on Different Screen Sizes ### Urlbox - Screenshot Service API ![image5](/content/testing-screen-sizes/image5.png) Urlbox is a powerful screenshot service API that allows you to capture [full-page screenshots](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md) of websites on various devices and viewports.

Source: https://urlbox.com/track-customer-feedback Last updated: 2023-05-29 --- No matter your business, you must have products or services that solve your customers’ challenges, craft marketing messages that resonate with your ideal audiences, and deliver a satisfactory customer experience. But all these are easier said than done — what exactly are your customers thinking, and what do they want? Luckily, you don’t need a crystal ball to find the answers. Customer feedback can help you unlock business success with an in-depth understanding of the market landscape and customer demands. Let’s explore the five ways to monitor customer feedback, how the input can benefit your brand, and the three key steps to get the most out of these customer comments. ## What is customer feedback? Customer feedback is verbal or written comments from your customers about their experience with your brand, products, or services. It can be positive, negative, or neutral and is shared through interviews, surveys, social media, emails, focus groups, and more. Customer feedback can help you understand buyers’ demands to improve your products and services. As [82%](https://www.redpointglobal.com/press-releases/70-percent-of-consumers-say-they-will-exclusively-shop-with-brands-that-personally-understand-them-this-holiday-season/) of consumers expect retailers to accommodate their preferences, the insights can give you a competitive edge. You can identify your strength, shape your unique selling proposition, and refine your target audience. You can also leverage the learnings to address customer issues, reduce churn, and improve customer satisfaction to [increase customer loyalty and profits](https://hbswk.hbs.edu/archive/the-economics-of-e-loyalty). With [98% of consumers](https://www.emarketer.com/content/surprise-most-consumers-look-at-reviews-before-a-purchase) using online reviews to support their decision-making and [82%](https://www.surveymonkey.com/resources/lp/elevate-buyer-trust-report/) trusting customer opinions over what brands say, sharing customer feedback on your website and social media can help you build trust with shoppers and drive sales. ## 5 Ways to monitor customer feedback There are various ways to collect customer feedback — some can help you gain a bird’s-eye view, while others allow you to get in-depth insights. ### Customer feedback surveys You can create an online survey using tools such as SurveyMonkey, Typeform, or Zoho Survey and send the link to your customers (e.g., via email, social media, or chat.) You may also ask the questions in person or over the phone. This method allows you to reach many people simultaneously at a relatively low cost. Since these surveys are typically brief, people are likely to complete them. They’re also versatile — you can use surveys to gather a broad range of data, including demographic information, product ratings, customer satisfaction levels, and more. However, you must be aware of the balance between getting more feedback and gaining in-depth insights. Keeping the survey short and sweet will likely generate more responses. Still, the volume often comes at the expense of granularity and nuances you can only learn from in-depth conversations. ### Product ratings and reviews You can ask customers to send feedback to you via email, fill out a form in-store, or post reviews on your website and third-party review sites (e.g., Yelp.) You can use a [website archive tool](https://urlbox.com/website-archive-tools.md) like urlbox to keep a record of all the feedback. This method helps you kill two birds with one stone: You can learn about customers’ opinions while leveraging the reviews to build trust and drive sales. Responding to posts on review sites also shows that your brand cares about its customers, which can help build trust with prospects. On the flip side, if you don’t have the resources to monitor all the channels and leave negative comments unaddressed, they could fester and damage your reputation. Also, you have less control over what people post and how the content is perceived. ### Customer interviews and focus groups These one-to-one and one-to-few methods allow you to collect in-depth feedback in person, over the phone, or via video calls. You can ask customers open-ended questions and have dialogues to understand the nuances of their answers. Additionally, focus groups help you get different perspectives and observe how customers interact with each other. Focus groups can be costly, while the one-on-one nature of interviews often limits the number of customers you interact with. These constraints may lead to a narrower range of opinions because customers willing to participate in these conversations most likely already have a positive relationship with your brand. ### Exit interviews As the saying goes, never let a good crisis go to waste. Even when customers leave your brand, you can gain insights from their decision to improve your products and services. Exit interviews help you understand why customers decide to stop buying from you. A one-on-one conversation allows you to gain in-depth insights, while a short customer cancellation/churn survey can help you understand broad-stroke trends and sentiments. ### Social media reviews and comments Meet your fans and customers where they are on various social media channels. You can ask for feedback and reviews on your social media pages or in customer service messages at scale. This method fosters two-way conversations with your followers and nurtures relationships while helping you learn about customer preferences. Like third-party sites, you should promptly respond to comments and answer questions to create a positive impression. Besides allocating resources to monitor various social media platforms, you should use a [social media archive tool](https://urlbox.com/social-media-archive-tools.md) to keep records of these comments to protect your brand against lawsuits, stay compliant with public record laws, and analyze data to identify trends. ## Benefits of customer feedback Collecting, analyzing, and responding to customer feedback is extra work. Why should you care? Customer feedback gives you critical insights you can’t get anywhere else by directly answering the question, “What do your customers want?” The learnings can help you focus your resources on making meaningful progress and foster effective cross-functional collaboration. You can use the findings to identify trends, inform product development, understand your strengths and areas for improvement, learn about your ideal customers, improve customer service, and craft marketing messages that resonate with the right audience. Meanwhile, listening and responding to your customers helps you nurture relationships, build trust with your fans and followers, make them feel heard, and enhance your reputation as a customer-centric brand. Additionally, you can identify where customers may have the most challenges making purchasing decisions, using your products, getting support, or interacting with your brand. You can address the issues by creating self-service content, improving website flow, and adjusting product design to augment the customer experience. The bottom line? Gathering and responding to customer feedback can help you boost customer satisfaction, improve customer retention, allocate your resources strategically, drive more sales, and increase profits. ## How to collect, analyze, and respond to customer feedback Let’s break down the customer feedback process into three main steps and see how you can get the most out of them: ### Step 1: Collect customer feedback People prefer to share their thoughts via different channels, so you should use various touchpoints to collect feedback. These include online or paper surveys, social media, email, phone or video calls, and in-person interviews. Craft specific and clear questions to elicit actionable feedback. For example, instead of asking, “What do you think about this product?” you may ask, “Does this product help you do XYZ? If not, what changes can we make to help you achieve your goals?” You can also get more people to respond to your survey and provide feedback by incentivizing your customers. Offer discounts or loyalty points, enter them into a draw, or send them a small gift. Of course, don’t forget to thank them for their time. ### Step 2: Analyze customer feedback To generate meaningful insights from customer feedback, you must organize the input, understand patterns, identify areas for improvement, and prioritize the issues. Categorize feedback with sentiment analysis, topic modeling, keyword analysis, etc. Then, look for trends and patterns. For example, you may realize that customers from a specific demographic are more likely to have difficulty using a feature, or a business area (e.g., post-purchase customer care) receives more negative feedback. With these insights, you can identify and prioritize areas for improvement to focus your resources on issues most important for your customers. ### Step 3: Respond to customer feedback Thank your customers and respond to their comments. The gesture shows that you value their opinions and prioritize their needs. Send a thank you note, provide a refund (if the customer complains about a product,) or acknowledge their input when you release an improved product based on their feedback. Your responses should be timely, sincere, and specific. Customers want to know that you aren’t just trying to placate them but have plans to address their concerns. Also, respond with a positive tone — you may not be able to fix every problem, but you can try to improve the situation and win hearts and minds. ## Unlock business success with customer feedback Customer feedback allows you to establish two-way conversations with your audience to improve your products and services, augment your brand reputation, and deliver a converting customer experience. So how do you know your efforts are paying off? Use a [brand monitoring tool](https://urlbox.com/brand-monitoring-tools.md) and [track brand mentions](https://urlbox.com/brand-monitoring.md) to stay current with customer sentiments, keep tabs on your reputation, and address concerns before they fester into serious issues. Customer feedback is a treasure trove of insights — are you ready to leverage them strategically to build a customer-centric brand? --- # Generate website screenshots from URLs in Airtable > Learn how to grab a screenshot from a URL in a record in an Airtable base Source: https://urlbox.com/automated-screenshots/url-screenshots-airtable Last updated: 2025-03-21 --- In this article we'll show how you can capture various website screenshots from a list of URLs in Airtable using the Urlbox [website screenshot API](https://urlbox.com/screenshot-api.md). Urlbox has been [converting URLs to images](https://urlbox.com/url-to-image.md) since 2012 it's wonderful to be bringing that power to Airtable 10 years later. ![airtable gif](/content/airtable/airtable-screenshots.gif) ## Create a new Airtable base with a list of URLs In Airtable we'll create a new Base called URL Screenshots. -> Or, you can skip this step and view the Airtable base used in this article here: [https://airtable.com/shrnEO30ijQ3FdcCy](https://airtable.com/shrnEO30ijQ3FdcCy) In our table we'll add 5 columns: - One column named *URL* with `URL` type This column will be filled with several URLs that we want to take website screenshots of - A second column called *Screenshot* with `Attachment` type - A third column called *Mobile Screenshot* also with `Attachment` type - A fourth column called *Full Page Screenshot* with `Attachment` type - A fifth column called *H1 Screenshot* with `Attachment` type ![airtable base with list of urls](/content/airtable/airtable-urls.png) We now want to make a new view called `URLs without Screenshots` which we will add some filters to: ![airtable view with filters](/content/airtable/airtable-filters.png) The filters should be where `URL` is not empty and all other columns are empty. This will give us the list of URLs that do not have screenshots yet, which we will use in the next step. ## Automating screenshots with a Zapier zap Great, now let's jump into our Zapier dashboard and create a new Zap. We will find the Airtable integration and use that as our trigger. Choose 'New Record' as the trigger event. ![airtable zapier](/content/airtable/airtable-zapier.png) On the next step, you'll be asked to sign in to Airtable. In order to do this, you'll need to copy your API key from Airtable in your account page: ![airtable api key](/content/airtable/airtable-apikey.png) and paste that into the popup window from Zapier: Now we can configure the Airtable settings. We need to tell Zapier to pull records from the 'URL Screenshots' Base, in the URLs Table. We also want to limit Zapier to only pull records from the view we just setup, which we called 'URLs without Screenshots'. This prevents Zapier pulling in records that have already been processed by the zap. ![airtable zapier settings](/content/airtable/airtable-zapier-setup.png) Once you test this setup in Zapier you should see one of the records from the Airtable view show up in the zap editor: ![airtable zapier record](/content/airtable/airtable-zapier-record.png) Great, now we can setup the Urlbox action to take various screenshots of each URL. ## Set up the Urlbox action to take screenshots of the URL Click continue to create a new step in the zap. Choose the Urlbox app and choose *Generate Screenshot From URL* as the action event: ![airtable-zapier-urlbox](/content/airtable/airtable-zapier-urlbox.png) Now either connect your Urlbox account by copying your Urlbox *secret* key into the pop-up box opened by Zapier, or if you've previously configured Urlbox in Zapier, choose your Urlbox account. On the next step, you'll want to map the `URL` column from the Airtable record to the `Url` field in the Urlbox action: ![zapier map fields](/content/airtable/zapier-map-fields.png) You can choose any other options and click continue. For example, if you want to block cookie popups from the screenshot, choose to set the Hide Cookie Banners option to true in Zapier. You could also block ads from the screenshot by setting Block Ads to true. Once finished, click the Test & Continue button to add another step. ## Add full page, mobile and selector screenshots Create another Urlbox step, once again map the URL field to the URL input. This time change the viewport dimensions to 320x600. We can do this by setting the width option to 320 and height option to 600. ![zapier-urlbox-width-height](/content/airtable/zapier-urlbox-width-height.png) You can rename this step to 'Get mobile screenshot'. Add more Urlbox steps to the zap, and map the url field as before. Each step should have different settings in order to generate different types of screenshot. These are going to correspond to the columns we setup in Airtable. One step should generate a full page screenshot, by setting the Full Page option to true. Another step will tell Urlbox to take a screenshot of a specific element on the page. For our example we will target the H1 element on the page by setting the **selector** option to `h1`. As this is a fairly common element on most websites, we should expect screenshots of the main heading of each page. ![zapier selector field](/content/airtable/zapier-selector-field.png) Each of these Urlbox screenshot steps in Zapier can be renamed to something more meaningful so that the final step's input can be mapped more easily. Here is what your zap should look like now: ![zapier urlbox steps](/content/airtable/zapier-urlbox-steps.png) ## Saving the screenshots back to the Airtable table The final step will use the Airtable integration again in order to save the screenshots back to the correct columns in our table. Choose the Airtable integration and choose Update Record as the action event: ![zapier airtable update record](/content/airtable/zapier-airtable-update-record.png) Once again, select your Airtable account and choose the Base and Table that you want to update. ### Mapping the record ID Crucially, the Airtable record needs to correspond to the *current* record being processed, so ensure that you map the `Record` input to the record `ID` from the *first* Airtable step: ![airtable-map-record-id](/content/airtable/airtable-map-record-id.png) ### Mapping the Screenshot URLs to the correct columns Now it is just a case of mapping the Screenshot URL output from each Urlbox step we setup above, to the corresponding column in our Airtable record. This is where re-naming our Urlbox steps comes in handy: ![airtable-map-screenshot-url](/content/airtable/airtable-map-screenshot-url.png) -> You might notice that the Screenshot URL output for each Urlbox step is the same. This is simply sample data that is used by Zapier to create the zap. Once the zap is run, these Screenshot URLs will be replaced with the actual screenshots. Once the screenshots are mapped to the correct columns, click continue. You can skip the test on the next step, as this will just save our dummy screenshot to your Airtable record, rather than the actual screenshot. Now you're ready to turn on the zap and run it.. ## Running the zap Turn the zap on and Zapier will run it once every 15 minutes (or however frequently your plan allows). You can manually run the zap too by clicking on Run Now button: ![manual run zap](/content/airtable/manual-run-zap.png) You should see the following pop up when the zap is run manually: ![zap running](/content/airtable/zap-running.png) Switch over to your Airtable, and watch the screenshots get generated *automagically*: Great, we have now learned how to generate several kinds of website screenshots from a list of URLs in Airtable. ## Bonus - Getting the URL to the screenshot images Since we stored the screenshot URLs in Airtable attachment columns, the image files have been saved to Airtables own cloud storage. If we want to get a direct link to these assets, we can add a new column to our table. Create a new column of type `Formula` and call it Screenshot URL. Paste this into the Formula field (thanks to [this comment](https://community.airtable.com/t/formula-to-get-image-attachment-url/15285/3)), replacing `Attachment Field` with the column name of the attachment field, in my case this is `Screenshot`. ```zsh RIGHT(LEFT({Attachment Field}, LEN({Attachment Field}) - 1), LEN(LEFT({Attachment Field}, LEN({Attachment Field}) - 1)) - SEARCH("https://", {Attachment Field}) + 1) ``` ![screenshot url column](/content/airtable/screenshot-url-column.png) If that worked, you'll end up with a column filled with direct links to the screenshot images: ![screenshot url column](/content/airtable/screenshot-url-column-list.png) You can repeat this step to get the direct links to the other types of screenshots. ## Alternative - use Data Fetcher to create screenshots in Airtable ![Data Fetcher Urlbox Integration](https://media.graphassets.com/ainf9ijQuTswLuIJ7Ngr) You can also use Data Fetcher's [Urlbox integration to create screenshots in Airtable](https://datafetcher.com/blog/how-to-create-full-page-screenshots-in-airtable-using-urlbox). Data Fetcher is an Airtable extension, so you can set up the integration and see the output without leaving Airtable. Another thing that makes Data Fetcher stand out is you can run the Urlbox integration from a [webhook](https://help.datafetcher.com/create-requests/run-request-using-webhook).

We saw how to use Zapier to pull records in from Airtable, generate various kinds of screenshots in Urlbox, and update the records in Airtable with the screenshots. You can also use Zapier and Urlbox to [schedule website screenshots](https://urlbox.com/automated-screenshots/automate-website-screenshots-schedule.md) --- # How to Classify Web Pages with ChatGPT > Delve into the practical applications and benefits of web page classification for businesses with the help of ChatGPT. Source: https://urlbox.com/web-page-classification Last updated: 2023-08-28 --- Web page classification involves categorizing web pages by examining their content, structure, or other characteristics. Search engines use web page classification to filter and rank search results, ensuring users are presented with the most relevant content. Online advertising platforms also benefit from classification, as they can target ads based on the content of the pages where they appear. One of the main challenges in web page classification is accurately assigning a given web page to one or more predefined classes based on its content and structure. This task can become highly complex with the sheer volume of web pages and the diversity of online content. Web pages can mix text, images, video, and other media, spanning multiple topics. More than that, the classification criteria themselves can be subjective, making it even harder to create an accurate and consistent system. In this article, we’ll cover some of the most common ways web pages are classified. We'll also delve into the practical applications and benefits of web page classification for businesses, from improving user experience and search engine optimization to enabling more effective targeted advertising. ## Why is web page classification important? In the age of information overload, it's not uncommon for a simple search on Google to yield millions of results, making it impossible for users to sift through each page to find relevant information. Given this overwhelming volume of information, we can use web page classification to personalize our online experience by recommending content relevant to our interests. Another approach is to build a classifier that can pre-identify which URLs in search results are important and relevant to what the user is looking for. These strategies can significantly improve the efficiency and effectiveness of online search and discovery, helping users find the information they need more quickly and with less effort. ## Types of web page classification Web page classification can be approached from several angles, depending on the specific goals of the classification task. These approaches differ in terms of the criteria they use to categorize web pages and the level of detail and granularity they offer. ### Article / Non-article The distinction between articles and non-articles is crucial for many web-related tasks, such as search engine optimization, content curation, and targeted advertising, as it helps identify a web page's primary purpose and audience. You can use AI to group all pages classified as blog posts versus all pages that serve different purposes, such as privacy policy pages, contact pages, or landing pages. ### Sales / Informational Another important type of classification is between sales pages and informational pages. Sales pages are designed with the primary goal of converting visitors into customers. They often include persuasive language, calls to action, and pricing information. On the other hand, informational pages aim to provide valuable content, educate the audience, or offer solutions to specific problems without directly selling a product or service. Understanding this distinction is vital for businesses and marketers to allocate resources effectively. For instance, sales pages may require more aggressive SEO strategies and targeted advertising to drive conversions. In contrast, informational pages benefit from high-quality content and backlinks to improve their authority and search ranking. ### Curated / User-generated This classification can help businesses understand and manage the types of content they offer on their platforms. Curated content is carefully selected, edited, and organized by the business or its editorial team. This type of content often reflects the brand's voice, expertise, and strategic messaging. It allows companies to control the narrative, ensuring that the information presented aligns with their goals and values. As its name suggests, User-Generated Content (UGC) is created by the users or customers of the service. This can include reviews, testimonials, forum posts, and social media mentions. UGC adds a layer of authenticity and social proof to a business, as it represents the unfiltered voice of the customer. Classifying web pages based on these two factors has practical implications that can significantly impact a business's bottom line, as it allows for a more organized and targeted approach to content management. ### E-commerce The ability to accurately classify web pages as being part of an e-commerce site has several practical implications. One use case is online advertising. Identifying e-commerce websites gives advertisers the opportunity to target ads to users who are already browsing specific e-commerce sites and tailor their advertising campaigns specifically for potential customers, increasing the likelihood of conversions. Another use case is market analysis. Business analysts can take advantage of this classification by directly browsing product pages without surfing various irrelevant pages. This classification also allows for tracking consumer reviews, ratings, and feedback, helping businesses improve their products and services based on customer input. ## Ways to classify web pages Each method of classifying web pages has advantages and limitations, and your choice depends on factors such as the number of web pages you want to classify, your desired accuracy level, and the task's specific requirements. Let's explore traditional classification methods and see how ChatGPT revolutionizes the process. ### Manually Manual classification involves a human analyzing the content of a web page and categorizing it based on predefined criteria. This method can be effective when dealing with a small number of web pages, and using a tool like Excel can help facilitate the process by creating spreadsheets to organize and keep track of the categorized web pages. The most significant disadvantage to this method is that it’s time-consuming, tedious, and impractical when dealing with a large number of pages. You also run the risk of human bias and inconsistency in classification. While manual classification can be helpful for specific tasks, it's not the most efficient option, especially when automated, more scalable methods are available. ### Machine Learning Algorithms Machine learning algorithms can be trained on labeled data (web pages that have already been categorized) to learn patterns and features that distinguish different types of pages. Once trained, the algorithm can automatically classify new, unlabeled web pages. Machine learning offers the advantage of quickly processing large amounts of data with high accuracy and consistency. The downside? This approach requires a certain level of technical expertise to implement and fine-tune the algorithms. Moreover, training a machine learning model requires a labeled dataset, which may not be readily available. ### ChatGPT ChatGPT can help you classify web pages even if you don’t have a deep understanding of technical jargon or possess the advanced technical expertise required to use machine learning. You just have to ask it to do so. And, to make things even more efficient, you can use tools like [URL2Text](https://url2text.com/) to convert web pages into pure text by stripping unnecessary HTML tags, inline CSS, and JS scripts. This conversion reduces token usage, saving costs, especially when summarizing complex web pages. You can then paste the text into a chat inside ChatGPT’s UI or send it to the OpenAI API to classify web pages at scale. When using URL2text, chunk the text carefully to maintain context across each piece, as the accuracy of the classification depends on the quality of the chunking and conversion process. If done correctly, this method can lead to high-quality classifications without the need for extensive technical expertise. Here’s a great example of how to [tag and categorize content with ChatGPT](https://medium.com/@roeibaraviv/how-to-tag-and-categorize-your-content-using-chatgpt-af9ac58b5c18) via the OpenAI API. ## Conclusion If you want to optimize your online presence, consider the power of web page classification. It's not just for search engines and ad platforms; it's a game-changer for any business aiming to achieve specific goals, from boosting sales to building brand loyalty. With ChatGPT, you can simplify this complex task, gaining both speed and accuracy that manual methods can't match. So, what's the next step for you? Start by evaluating your existing web content. Use ChatGPT to categorize your pages into meaningful classes like Curated / User-Generated or Sales / Informational. This will give you actionable insights into how each type of content serves your business objectives. From there, you can tailor your content strategy, SEO efforts, and advertising campaigns to be more effective and targeted. In closing, don't let the complexity of web page classification intimidate you. With tools like ChatGPT, you're well-equipped to tackle this challenge head-on. --- # How To Screenshot a Web Page - The Full Guide > This article will teach you how to screenshot a web page based on what you plan on doing with the final image. Source: https://urlbox.com/automated-screenshots/how-to-screenshot-a-web-page-full-guide Last updated: 2025-03-21 --- Capturing a screenshot of a web page is a relatively straightforward process that can be done by using: - the built-in functionality of your operating system (Windows, macOS, Android, etc.) - a third-party app that will upload your screenshot to their servers - the built-in functionality of your browser - a browser extension - no-code tools and screenshot APIs (to automate this process). This article will teach you how to screenshot a web page using any of the methods mentioned above. ## What screenshot method is best? It depends on what you are planning to do with the screen capture. Is it for personal use or business-related? You probably don't need a high-resolution image if you keep it for yourself or share it with friends. The best way to screenshot a webpage is by using your device's built-in functionality or a simple third-party app. On the other hand, if you want to add a screenshot to a work presentation or an investor's pitch deck, it'd be best to go with a dedicated service that can generate pixel-perfect images. Most of these screenshot tools allow you to change the image's file type (JPEG, PNG, PDF, etc.), plus they can even help you capture a [full page screenshot](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md). But if you need to capture webpages at scale, you will have to use a dedicated [screenshot API](https://urlbox.com/screenshot-api.md), like [Urlbox](https://urlbox.com/.md). Now that you know which method is best, it's time to jump straight into the process. ## How to screenshot a web page on Windows Capturing a screenshot on your Windows machine is extremely easy. All you have to do is press 2 keys on your keyboard simultaneously. ![image6](/content/web-page/image6.jpg) If you want to capture AND save your screenshot, press the "PrtSc" and the "Windows" keys simultaneously. This will capture your entire screen and save a PNG image in the dedicated screenshot folder. You can access this folder by going to "This PC" -> "Pictures" -> "Screenshots." Notes: - you must use a photo editing app to crop the screenshot (Paint works just fine). - this method captures a fullscreen screenshot, meaning that if you have multiple monitors, your screenshot will feature everything displayed on all of them. If you want to capture AND copy the image to the clipboard, you can simultaneously press the "PrtSc" and the "Alt" keys. Now you can simply paste the image into your preferred photo editing app. This method works with Paint, Figma, and even Photoshop. Remember that you'll have to manually crop the screenshot to save a web page, not your entire screen. ## How to screenshot a web page on Mac Capturing screenshots on Mac is also straightforward. You can take a fullscreen screenshot by pressing the "Shift," "Command," and "3" keys at the same time. ![image3](/content/web-page/image3.jpg) You should immediately see a thumbnail in the corner of your screen. If you click on the thumbnail, you'll be able to edit the screenshot, which is a must if you want it to feature the contents of a web page and not your whole screen. On the other hand, you can capture a specific part of your screen by pressing the "Shift," "Command," and "4" keys at the same time. Drag the crosshair to select which area of the screen you want to capture. You can also cancel this process by pressing the "Escape" key on your keyboard. Your screenshots will be saved on your Desktop with the name ”Screen Shot \[date] at \[time].png.” ### Third-party screenshot tools There has been a surge of third-party screenshot tools in recent years. What makes them really popular is the ability to add elements on top of your screenshot. ### Lightshot - Best third-party screenshot tool for Mac and Windows My favorite third-party screenshot tool is Lightshot. Of course, this is a personal preference, and you can pick any other, but I decided to stick with Lightshot after testing countless apps. ![image7](/content/web-page/image7.jpg) It's free to use and very lightweight. It works on Mac and Windows machines and is available in more than 10 languages. In addition, it has built-in editing tools to draw lines, arrows, rectangles, or add extra text on top of images. But the best Lightshot functionality I use daily is the "Upload screenshot" option. This uploads your screenshot to Lightshot's servers and generates a unique URL you can share with anyone. It's great because it makes collaboration extremely easy. Here's what a link generated by Lightshot looks like: [https://prnt.sc/qJVdAFwLc9my](https://prnt.sc/qJVdAFwLc9my). ![image5](/content/web-page/image5.jpg) You can also download their Chrome extension if you don't want to install it locally; just remember that this will work inside the browser window. It's best if you want to screenshot web pages and nothing else. This brings us to the following method. ## How to screenshot a web page in a browser All browsers have some sort of built-in screenshot functionality to capture a part of a web page. If that is not enough, you can install third-party extensions, like the previously mentioned Lightshot. ### How to capture a screenshot in Chrome Capturing a screenshot with Chrome's built-in functionality can be a pain for non-technical people. Here's an example of how to capture a [full page screenshot](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md#best-tools-to-take-a-full-page-screenshot-of-a-single-web-page-in-chrome) in Chrome. Click on the link to read the step-by-step process. ![image1](/content/web-page/image1.png) I highly recommend you go for an extension if you use Chrome as your default browser (like Lightshot, Full Page Screenshots, etc.). ### How to capture a screenshot in Mozilla Firefox It's way easier to capture a screenshot in Firefox compared to Chrome. All you have to do is right-click on an empty part of the page and select "Take Screenshot." Alternatively, you can press the "Ctrl," "Shift," and "S" keys at the same time. ![image2](/content/web-page/image2.jpg) Once you are satisfied with how the screenshot looks like, you can save it locally or copy the image to your clipboard. If you go with the second option, you can paste it into a photo editing app or directly on your preferred chat app (like Slack, Discord, Messenger, WhatsApp, etc.). ### How to capture a screenshot in Microsoft Edge Microsoft Edge features the best built-in screenshot functionality of all other browsers. To capture a snapshot of a web page, you'll have to press the "Ctrl," "Shift," and "S" keys at the same time. This will open up the screenshot menu at the top of the page, which allows you to either capture a full page screenshot or select an area of the screen. ![image8](/content/web-page/image8.jpg) The best part is that you can write on top of the screenshot right after it has been generated. There are not many browsers that let you do this by default. Now let's move to something a bit more advanced. The following method best suits businesses looking to automate the screenshot process. ## How to automatically screenshot a web page with Zapier You'll need a [website screenshot generator](https://urlbox.com/screenshot-api.md) to automate screenshots with Zapier. As the name suggests, a service like this simply takes in a URL or HTML file and returns a screenshot of it. Zapier automations are called Zaps. Each Zap is comprised of a Trigger and at least one Action. ### Setting up the Trigger The Trigger is what tells the Zap to start working. This means you'll have to set up a condition that will trigger the screenshot. Here are a few trigger examples to better put things into perspective: - Run the Zap every hour, day, week, or month - Run the Zap when you like a Tweet - Run the Zap when a new row has been added to a Google Sheets document. As you can see, the primary purpose of the Trigger is to set the Zap in motion. Here are a few use cases based on the above triggers: - Take a screenshot of a web page every day - Take a screenshot of the Tweet you liked - Take a screenshot of a web page found at the URL you pasted in the Google Sheets document. Note: I've written a step-by-step guide that goes over the process of [building a swipe file with Urlbox and Zapier](https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier.md). You can follow the steps to automatically capture screenshots of specific URLs you paste into a Google Sheet document. It's important to mention that your trigger doesn't necessarily have to return a URL. In this case, you must sign up for one of Zapier's paid plans. This will allow you to add multiple Actions to your Zap. Setting up the Action This step is crucial for your Zap. You have to tell Zapier what it should do when the trigger is executed. As described in the step-by-step guide on [how to build a swipe file with Urlbox and Zapier](https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier.md), you must use a website screenshot generator to capture a snapshot of a URL. ![image9](/content/web-page/image9.jpg) As you can see in the above screenshot, I configured Urlbox to "Generate Screenshot From URL." You can configure the output format when the screenshot should be taken, plus many more variables. ![image4](/content/web-page/image4.jpg) You can see in the above screenshot that: 1\. I pass a dynamic URL from a Google Sheet cell; 2\. I instruct Urlbox to save the screenshot as a PDF file; 3\. I configured Urlbox to capture the screenshot only when all requests are finished, and the website has fully loaded. In addition, I have also configured Urlbox to capture a full page screenshot, as I want to save it for my swipe file. Now, you must set up a new Action if you want to save the screenshot to a cloud storage service (Google Drive, One Drive, pCloud, etc.). This is where you'll need a premium Zapier account, as the basic plan only allows you to set up a single Action. With prices starting at $19.99, I find Zapier relatively cheap compared to how much time it can save. You will also need a Urlbox account that goes for $19. The Starter plan allows you to take up to 2,000 screenshots each month and comes with all features (like blocking ads, retina-ready images, and much more). The best part is that you can start a [seven days free trial](https://urlbox.com/pricing.md) and enjoy a 30-day money-back guarantee. There is another way you can automate screenshots, but you either need to be a developer or get the help of one. You can learn more about it from our article that covers [how to convert links to PDF at scale](https://urlbox.com/automated-screenshots/convert-links-to-pdf.md) with screenshot APIs. ## Conclusion Capturing a screenshot of a web page is a straightforward process that can be achieved using the built-in functionality of your device or browser. You can use a third-party app or browser extension to generate higher quality, editable screenshots. You can also automate the process with the help of no-code tools like Zapier. Alternatively, you can get the same (or even better) result by implementing an API provided by a [website screenshot service](https://urlbox.com/.md). --- # What Is AI Detection and How Does It Work > Delve into what AI detection is and shed some light on the latest techniques employed by researchers, developers, and business owners to distinguish between human and AI-created texts. Source: https://urlbox.com/what-is-ai-detection Last updated: 2023-08-18 --- One of the most remarkable applications of AI is in content generation. And, as AI-driven content generation becomes more common, so does the challenge of discerning what’s real and what’s machine-made. Whether it's in the field of news media, academia, or entertainment, being able to determine the origin of a piece of writing is crucial for reasons that range from upholding journalistic integrity to ensuring fair attribution of scholarly work. Now modern AI models are designed to learn from vast amounts of data, enabling them to craft text that captures the nuance, style, and complexity of human language. And as AI-generated content becomes more convincing, detection techniques must evolve in tandem. Today's detection strategies rely on a combination of linguistic analysis, machine learning models, and metadata examination to differentiate between the products of human and machine minds. In this article, we’ll delve into what AI detection is and shed some light on the latest techniques employed by researchers, developers, and business owners to distinguish between human and AI-created texts. ## What is AI detection? AI detection, in the context of content generation, refers to the process of identifying whether a piece of content, such as a text, image, video, or computer code, was created by a human or an AI system. Detection methods range from simple heuristic approaches to sophisticated machine-learning models. In all cases, the goal is to accurately and efficiently classify content based on its origin: human or machine. Traditional detection methods, often employed by humans, usually rely on the identification of patterns, anomalies, or other telltale signs that might indicate AI involvement. For instance, one traditional method is linguistic analysis, where experts look for unusual phrasing, vocabulary, or syntax that might not be typical of human writing. Another method is metadata analysis, where examiners scrutinize the information attached to digital files (such as timestamps or digital signatures) to identify inconsistencies or patterns indicative of AI generation. In contrast, AI-powered detection employs machine learning models to automatically identify AI-generated content. One such tool is the "[Jigsaw's Perspective API](https://perspectiveapi.com/)," which leverages machine learning to identify toxic content, including AI-generated content that might be used to spread disinformation or hatred. Another example is the [AI-Writing-Detection](https://github.com/Nygosaki/AI-Writing-Detection) tool from GitHub, which is useful in identifying AI-generated text. These AI-powered tools offer the potential for quicker, more accurate, and more scalable detection than traditional methods, but their effectiveness can vary based on the quality of their training data and the sophistication of their models. ## How does AI detection work? Data plays a pivotal role in training AI models for detection. AI systems learn by being fed massive amounts of data, which enables them to recognize patterns, relationships, and associations. In the context of AI detection, models are typically trained on large datasets of both human-generated and AI-generated content. By analyzing these datasets, AI models learn to differentiate between the two based on subtle differences and patterns that might not be immediately evident to human observers. Over time, this exposure to data allows AI models to hone their detection abilities, becoming increasingly adept at distinguishing between human and machine-generated content. Machine learning and deep learning techniques are at the heart of AI detection: 1. Supervised learning: In supervised learning, AI models are trained on labeled datasets, where each piece of content is tagged as either human or AI-generated. This enables the model to learn the characteristics of both types and make accurate predictions when confronted with new, unlabeled content. 2. Unsupervised learning: Unlike supervised learning, unsupervised learning doesn't require labeled data. Instead, AI models analyze the structure and distribution of the content to identify patterns and clusters that may indicate whether it's human or AI-generated. 3. Neural networks: Neural networks are computational models inspired by the human brain. They consist of layers of interconnected "neurons" that process and transmit information. Deep learning involves using deep neural networks, which have many layers and can learn complex patterns in data. 4. Transfer learning: Transfer learning is a technique where a pre-trained model, which has been trained on one task, is adapted to a new but related task. This can be particularly useful in AI detection when there is limited data available for training, as models can leverage knowledge from related tasks. The techniques outlined above have paved the way for the development of powerful AI detection tools, some of which incorporate multiple approaches to improve detection accuracy and robustness. Let’s explore just one way you can create an AI detection system by leveraging ## How to quickly create an AI detection system It can take an incredible amount of time and resources to train an AI model from scratch. And things become even more complicated if you want to create an algorithm capable of detecting AI content. As a matter of fact, OpenAI has deprecated its [classifier](https://openai.com/blog/new-ai-classifier-for-indicating-ai-written-text) because it could not reliably identify if a text was written by a human or by an AI. Just think about it, if the company behind ChatGPT can not pull this off, then it might be a bit more difficult than expected. Even so, there are many online services claiming they can differentiate between AI-written content and human-generated one. And since we already know that this process is extremely complicated, it’s best to try them all and compare their results. ### Check the text with multiple tools [AI-Writing-Detection from Github](https://github.com/Nygosaki/AI-Writing-Detection) is a Python-based tool that can parse the inputted text into 9 existing AI writing detection tools and return the results. This can dramatically reduce the time needed to check if a piece of content is generated by AI or not. It’s also important to mention that these tools have proven to return false results, sometimes identifying AI content as written by humans and vice-versa. Moreover, each tool has its own limitations when it comes to the number of characters it can parse, making it hard or nearly impossible to check if full articles or news reports have been created by AI. ### Parse only what’s important If you are manually checking text files or small documents, then you shouldn't worry too much about the character limit, as you can simply copy and paste the exact body of text you want to analyze. On the other hand, if you want to automate the process and check live URLs, then you’ll need to strip down the HTML, CSS, and JS code of your target web page and extract its text contents. The fastest way to do this is by using a tool like [URL2Text](https://url2text.com/), which converts the HTML of any webpage to markdown, thus greatly reducing the number of characters you will feed the AI checker, which can possibly result in higher accuracy. In addition, you can use URL2Text in combination with the AI-Writing-Detection tool to quickly create an AI detection system. ## Can AI detection be wrong? AI is powerful but not perfect. Like all technologies, it can make mistakes due to issues like biased training data or algorithm limitations. For example, if an AI system is trained predominantly on data from one demographic, it might perform poorly when presented with data from a different demographic, leading to inaccurate or skewed results. Also, as environments, behaviors, and patterns change over time, an AI model that was once accurate might quickly become outdated. That’s why continuous learning and adaptation are crucial for maintaining the accuracy and relevance of AI detection systems. Keep an eye out for services that are constantly fine-tuning their models and are actively presenting this on social channels. It's also worth noting that while AI can process vast amounts of data at incredible speeds, it lacks human intuition and context awareness. Human judgment will still be superior to AI predictions for years to come. --- # Why Your Website Can't Be Archived (And How to Fix It) > Learn why modern frontend patterns like modals and SPAs break compliance archiving and how to architect your site for reliable screenshot capture. Source: https://urlbox.com/why-your-website-cant-be-archived Last updated: 2026-04-03 --- "Why can't I just screenshot my website for compliance?" That's a question we get regularly from customers in regulated industries. Financial firms, healthcare organizations, and other businesses need to archive their websites for compliance purposes. It sounds straightforward — just point a headless browser at your URLs and save the screenshots. But when you try this approach, you quickly discover that half your content is missing. ## The naive solution (that everyone tries first) Most engineers approach website archiving the obvious way: configure a headless browser to click through your site's interactive elements. You write selectors to target modals, accordions, and hidden sections: ```json { "url": "https://example.com/", "click": ["a[data-bs-target='#products-modal']"], "scroll_delay": 2000, "format": "png" } ``` This should work, right? Click the modal trigger, wait for it to open, capture the screenshot. For simple cases, it does work. You can automate clicks on buttons, wait for animations to finish, and capture the revealed content. ## Where it breaks down The problem isn't technical complexity — it's reliability. When you're dealing with compliance requirements, "mostly working" isn't acceptable. Here's what goes wrong: **Hidden UI elements** — Modals, dropdown menus, accordion panels, and slide-out drawers all hide critical content behind JavaScript interactions. Each one requires custom automation logic. **Timing issues** — JavaScript-heavy sites load content asynchronously. Your automation might click a button before the handler is attached, or capture a screenshot before an animation completes. **Non-deterministic behavior** — A/B tests, personalization engines, and dynamic content mean the same URL can render completely different content on different requests. **PDF and iframe rendering** — Embedded documents often fail to load properly in headless browsers, leaving blank spaces in your archives. **Fragile selectors** — CSS classes like `.css-1dbjc4n.r-18u37iz.r-13qz1uu` break when developers deploy updates, requiring constant maintenance of your automation scripts. For our financial services customer, this meant regulatory documents were sometimes missing from their archives. In a compliance audit, that's not just inconvenient — it's a liability. ## The key insight **Compliance requires deterministic states, not simulated interactions.** When you're archiving content for legal or regulatory purposes, you need certainty. Every required piece of information must be captured reliably, every time. The problem isn't that headless browsers are bad at automation. The problem is that modern web applications aren't designed for programmatic access to their content. ## The architectural fix Instead of fighting your frontend framework, design your site so that every compliance-critical state is directly addressable. **Make each state a unique URL:** ``` https://example.com/ # Homepage https://example.com/#products-modal # Products modal open https://example.com/#team-bios # Team biographies expanded https://example.com/#regulatory-docs # Regulatory documents visible ``` **Ensure pages load into the correct state:** - URL fragments should trigger the appropriate modals or sections to open automatically - Server-side rendering should handle initial state where possible - Avoid hiding compliance-critical content behind JavaScript-only interactions **Example implementation:** ```javascript // React component that opens modal based on URL hash useEffect(() => { if (window.location.hash === '#products-modal') { setModalOpen(true); } }, []); ``` This approach transforms screenshot capture from brittle automation into simple HTTP requests. ## Why modern patterns conflict with archiving **Single Page Applications** — SPAs often render different content at the same URL, making it impossible to directly link to specific states. **Modal-heavy UX** — Modals provide good user experience but terrible programmatic access. Users can bookmark the modal URL, but headless browsers can't. **JavaScript-gated content** — Hiding content behind click handlers makes it inaccessible to automated tools, search engines, and compliance systems. **Lazy loading everything** — While lazy loading improves performance, it makes full-page capture unreliable when combined with complex interactions. These patterns aren't inherently bad — they solve real UX problems. But they create a fundamental conflict between "good UX" and "archivable content." ## Broader implications This isn't just a screenshot problem. The same architectural issues affect: **LLM access** — AI systems struggle to access content hidden behind interactions, limiting their ability to understand your full site. **Search engines** — Google can execute some JavaScript, but complex interaction flows remain largely invisible to crawlers. **Accessibility tools** — Screen readers and other assistive technologies have similar limitations with dynamically revealed content. **Performance monitoring** — Synthetic monitoring tools can't easily test user flows that require complex interactions. ## Implementation guidelines **For compliance-critical content:** - Every required state must be accessible via a direct URL - Use server-side rendering where possible - Implement URL fragment handling for client-side state - Avoid multi-step interactions to reveal required information **For general content:** - Progressive enhancement: ensure core content loads without JavaScript - Use semantic HTML that describes content structure - Implement proper loading states and error handling **Testing your approach:** ```bash # Can you reach every required state with a simple HTTP request? curl https://example.com/#products-modal curl https://example.com/#regulatory-docs curl https://example.com/#team-bios # Does each URL return the complete content in a single request? ``` If you need to simulate clicks or wait for animations to capture required content, your architecture isn't compliance-ready. ## The engineering tradeoff This approach requires upfront architectural planning. You're choosing deterministic access over some UX conveniences. But the benefits extend beyond compliance: - Reliable automated testing - Better search engine indexing - Improved accessibility - Simplified performance monitoring - Future-proof content access The alternative — maintaining brittle automation scripts — becomes more expensive over time as your site evolves. ## Making the change If you're retrofitting an existing site: 1. **Audit your compliance requirements** — identify every piece of content that must be archivable 2. **Map hidden content** — document what's currently behind interactions 3. **Design URL schemes** — create direct URLs for each required state 4. **Implement incremental changes** — start with the most critical content 5. **Test with simple tools** — verify each state loads correctly with basic HTTP requests For new projects, build this into your initial architecture. It's much easier to design for archivability from the start than to retrofit it later. *** Website archiving doesn't have to be an engineering nightmare. When compliance-critical content is architecturally accessible, capturing perfect screenshots becomes trivial. The real solution isn't better automation — it's better architecture. If you need to capture existing sites with complex interactions, [Urlbox](https://urlbox.com/.md) can handle the automation complexity for you. But for long-term maintainability, consider making your content directly addressable. Build for humans first, but design for robots too. --- # 6 ApiFlash Alternatives to Capture Screenshots at Scale > Explore top alternatives to ApiFlash for capturing high-quality screenshots.

But this much power also comes at a cost. ![image3](/content/brand-monitoring/image3.png) How it works Similar to some of the previous tools, all you need to do to start monitoring your brand is to add specific keywords you want to track.

BrowserStack provides a single platform for developers to manage all their browser tests from a single location, and it integrates with popular development tools like Git and Jira.

It can run tests on over 3000 browsers, real devices, and operating systems.

On the other hand, if you want to test your mobile apps, you must go with a dedicated Native App Automation plan. This goes for $125 per month and grants you access to many real mobile devices from brands like Apple (iPhone/iPad), Samsung, Google Pixel, OnePlus, Oppo, Vivo, and more. The next alternative focuses exclusively on mobile app testing, so if that's what you are looking for, keep reading. ## Kobiton - Browserstack Alternative for Mobile Apps Testing Kobiton is a Browserstack alternative focused specifically on mobile app testing.

Now, if you need more than that, you'll have to spend a minimum of $3,960 per year and go with the Accelerate plan. This plan will give you up to 3000 minutes of monthly testing and 10 Appium exports. ## SmartBear BitBar - Browserstack Alternative for Web App Testing BitBar from SmartBear is a great Browserstack alternative if you don't want to stress over how many minutes of live testing you have left.

Otherwise, pricing plans start at $47 per month per parallel test. This will grant you unlimited live testing minutes and unlimited users, many real devices, and browsers. For $155 per month per parallel test, you will get access to headless browsers and be able to run Selenium tests or tests created in TestComplete. The most expensive plan will cost you $212 per month per parallel test. This plan lets you run scripted automation tests and includes one live parallel with every automated parallel test. You can also save 25% on any plan if you pay yearly. So far, the alternatives we have covered are focused on live and automated testing of mobile and web apps. You can use them to test complex behavior and uncover functional bugs, but they might be a bit much if you simply want to ensure your website loads correctly on different viewport sizes. ## Urlbox - Best Browserstack Alternative For Website Render Testing And Archiving Urlbox is a blazing-fast [website screenshot service API](https://urlbox.com/screenshot-api.md).

Source: https://urlbox.com/data-archiving-tools Last updated: 2023-02-01 --- Data is precious. It is the most valuable asset of your business – or its biggest liability. Archiving data, including your website data, team records, and communication records is essential for eDiscovery and compliance with regulations such as HIPAA, SEC 17a-4, FINRA, GDPR, etc. In this article, you will learn about the importance of data archiving for regulatory compliance, different types of archives and the best archiving tools available on the market to meet legal and regulatory requirements. ## Why is Data Archiving Important? Regulatory compliance requires long data retention periods, so deleting data is not an option for most businesses. That's why organizations rely on data archiving tools to meet their legal and regulatory obligations for retaining and preserving data. Archiving data protects it from accidental loss or deletion, ensuring it remains available for future reference. Archiving also helps with efficient data management, enabling organizations to manage large volumes of data as they generate it. ## Types of Data Archives Businesses generate data from various sources, and all of it must be archived to protect against lawsuits and comply with regulators. ![image1](/content/data-archiving-tools/image1.png) For example, social media archives help store all the data from your social media accounts in one place. This allows you to ensure you have a record of everything posted on your social accounts in case any problem arises. Similarly, website archives contain copies of all the pages on your website. ### Social Media Archive This type of archive mainly consists of social media posts, comments, and communications. [Social media archiving tools](https://urlbox.com/social-media-archive-tools.md) make it easier to comply with public records laws, regulations, and recordkeeping initiatives. They can also be used to monitor trends, measure paid campaign performances, and uncover social media insights. ### Website Archive This type of archive consists of snapshots of the most important pages of a website at specific time intervals. This can be helpful for companies that need to provide evidence of their regulatory compliance and demonstrate that their website is up-to-date with the relevant standards at a given time. For example, if a company needs to prove to an auditor that they had the appropriate copyright information or product disclaimers on their site at any given time. [Website data archiving tools](https://urlbox.com/website-archive-tools.md) are designed to help companies comply with data privacy regulations. ### Other Data Archive Other data archives that help in complying with regulations and keeping essential data safe include: - Email archives - SMS archives - Internal communication software archives - Feature data from in-house communication tools like Slack, Teams, etc. - Client communication archives - Include data generated by sales reps and support agents during calls and chat discussions. ## Best Data Archiving Tools for Regulatory Compliance Choosing the right data archiving tool is essential for meeting regulatory compliance requirements. These tools must be able to archive any webpage and preserve all relevant data. Here are five of the most valuable data archiving software solutions on the market. ### [Urlbox](https://urlbox.com/wayback-machine-alternatives.md) - Best Website Data Archiving Tool Urlbox is an all-in-one data archiving solution that can capture screenshots of virtually any webpage.

For enterprise companies, the highest plan is $3,500/month and gives you access to capture up to 1,000,000 screenshots. Unlike other tools, Urlbox does not charge you based on the number of domains you want to archive, but on the number of records you generate each month. Depending on your needs, it is easy to scale up or down. ### Stillio - Easy-to-use Data Archiving Tool Stillio is an excellent solution for any business looking to regularly capture screenshots of their website and safely archive them.

However, their monthly pricing plans have been reported to start at $99. ### Wayback Machine - The First Data Archiving Tool Wayback Machine is an online archive of websites maintained by the Internet Archive. It allows users to view archived versions of web pages at various points in time, which can help recover lost or deleted information. ![image4](/content/data-archiving-tools/image4.png) Features Wayback Machine is extremely easy to use, as all you have to do is input a URL and pick a date and time in the past to see how a website looked like. Keep in mind this is a double-edged sword because there are no guarantees the Wayback Machine will capture daily or even weekly screenshots of that website. Moreover, you cannot control the archive uptime. If the web.archive.org website is down, you won’t be able to access archived web pages until it is back online, which can have dire consequences in case of an unannounced surprise inspection. I've added this tool to the list because it's one of the most renowned, but you should check other [Wayback Machine alternatives](https://urlbox.com/wayback-machine-alternatives.md) that can do a better job at archiving online records. Pricing Wayback Machine is the only free tool on this list. It is a non-profit digital library, so users can access it free of cost. ### Perma.cc - Data Archiving Tool to Generate Permalinks Perma.cc is an excellent tool for those who need to make sure their linked citations will never lead to broken, blank, altered, or malicious pages.

Explore their unique strengths and integration capabilities. Source: https://urlbox.com/getscreenshot-alternative Last updated: 2025-03-21 --- Integrating your favorite [screenshot API](https://urlbox.com/screenshot-api.md) tool with Zapier is useful for a variety of reasons.

In this article, we look at five of the best GetScreenshot alternatives, looking at their integration capabilities with Zapier and examining how each solution brings its own distinct strengths to the table. ## [Urlbox](https://urlbox.com/.md) ![image1](content/getscreenshot-alternative/image1.png) G2 rating: [4.8 out of 5 stars](https://www.g2.com/products/urlbox-io/reviews) Urlbox is an excellent alternative to GetScreenshot that stands out for its integration with Zapier and advanced capabilities.

While it has this capability, this tool’s customization options are comparatively more limited than those offered by GetScreenshot or Urlbox. However, one of its distinctive features besides its integration with Zapier is its accessibility for developers through its API, which allows them to blend the tool’s image generation capabilities into their apps and workflows. When it comes to pricing, their cheapest plan comes at just $14 per month for 1,000 images. The higher-tier plans have added benefits such as higher image limits, dedicated support, custom features, and configurations.

Source: https://urlbox.com/html-to-image-converters Last updated: 2025-03-21 --- Whether you are a web developer, marketer, or business owner, you may have at one point encountered the need to convert an HTML code to an image. There are several HTML code to image converters available, each with its own unique set of features. These converters can be used to turn HTML code into a range of image formats, including PDFs, JPGs, PNGs, and more. In addition, some of the tools we'll cover have extra functionalities that can prove extremely helpful in specific scenarios. This article will look at the five best HTML code to image converters on the market to help you decide which one is right for you and your business. We will compare each converter's features and pricing and look at each tool's pros and cons. ## Three Ways to Convert HTML to Image Converting an HTML file or [URL to image](https://urlbox.com/url-to-image.md) is a relatively simple process, but things get complicated once you start to scale to hundreds or thousands of conversions. That's why it's imperative to anticipate how many images you will need to generate before deciding on a tool. If you start using a simple converter but then need to scale up, you will have to start the process all over again, wasting lots of time and money. So here are three ways to convert HTML to image based on the number of images you need. Use an online converter - Best for a small number of conversions This is the easiest and quickest way to generate an image from HTML. An online converter is usually a website that lets you upload an HTML file and convert it to an image. The main problem with these tools is that most of them render the image using old technologies, which can result in broken layouts and poor-quality images. They are also bad at handling more than one conversion simultaneously. You should use an online converter if you want to convert a maximum of 5 HTML files to images. Code your own microservice - Best for a medium number of conversions This method requires a bit of programming knowledge or the help of a developer. By coding your own microservice, you can convert as many files as you want, but you will need quite the computational power if you start rendering tens or hundreds of files. In addition, you will need to fix possible bugs and constantly update your rendering engine to keep pace with new technologies (like flexbox). This method is best if you want to convert a large number of HTML files to PNGs or JPGs, but it's not great if you need professional-grade PDFs. Use a screenshot generator API - Best for a large number of conversions One of the best methods to convert HTML files or URLs to images is by using a [screenshot generator API](https://urlbox.com/screenshot-api.md). Not only will you be able to scale to hundreds of thousands of conversions, but you won't need to worry about fixing bugs or updating code. Plus, you can connect certain APIs to Zapier to automate the conversion process without writing a single line of code. This method is best if you want to convert many files or web pages to high-quality images in various formats. ## [Urlbox](https://urlbox.com/.md) - Best HTML to Image Converter Urlbox is a screenshot service API built specifically for businesses looking to convert URLs or HTML files to images. You can use it to: - quickly generate an image straight from the dashboard - as an API when building your own software - via the Zapier connector without writing code. ![](/content/html-to-image-converters/image5.png) Urlbox Pros Urlbox is the most comprehensive converter in this list in terms of features. You can choose between multiple image formats (PNG, JPEG, PDF, SVG, etc.), configure the image height and width, and even inject custom JS or apply custom CSS styles. All you have to do to generate a screenshot is add an URL or simply paste your HTML code. Once the image is rendered, you can download it, share it via its link, and even create a downloadable link you can embed on your website. Urlbox Cons Urlbox comes with a [7-day free trial](https://urlbox.com/pricing.md), after which you need to sign up for a paid plan. Prices start at $19 per month, allowing you to generate up to 2,000 images. So if you want to convert a small number of images each month, you should check other tools. ## [Convertio](https://convertio.co/html-jpg/) Convertio is an all-in-one online converter that can turn HTML files into images. The free plan allows you to upload any file (smaller than 100 MB) from various sources, like your computer, Dropbox, or Google Drive, and then automatically convert it into a JPG, PNG, GIF, SVG, or another format. More than 25,000 users have rated the conversion quality 4.5 stars out of 5, which shows that Convertio might struggle to render certain files correctly. ![](/content/html-to-image-converters/image2.png) Convertio Pros Convertio is extremely easy to use and has a plethora of different conversion options. You can turn any HTML file into an image, but it can also convert it into an eBook file (EPUB, MOBI, TCR, ETC.) or even a presentation type of file (PPT, PPTX, POT, etc.). You can convert files for free as long as they are smaller than 100 MB. Convertio Cons Convertio offers an API that works only with PHP, with Node.js and Python wrappers under development. So if you want to implement this service within your own application, it must be written in PHP. Converting larger files will require a paid plan, with prices starting at $9.99 per month. Convertio only works with HTML files, which means you can not convert live URLs to images. ## [Page2Images](https://www.page2images.com/Convert-HTML-to-Image-or-PDF-online) Page2Images is a free online file converter that can quickly generate an image from HTML code or via a URL. Unfortunately, you can't upload a file directly, so you will have to open your HTML document with an editor and manually copy and paste the code into Page2Images' website. They also provide an API to automatically generate screenshots from your application. You get 100 free credits to try out their API, after which you will need to upgrade to a paid plan, with pricing starting at $10 per month for 2000 credits. To access all of Page2Images' features, you must go with the XLARGE plan, which starts at $500 per month. ![](/content/html-to-image-converters/image4.png) Page2Images Pros Page2Images' output quality is excellent compared to the other free converters in this list, plus it almost matches that of Urlbox. You can render the image on devices like desktops, iPhone 4 and 5, iPads, and Android. Even so, you cannot manually configure the viewport, so your image will always feature a full-page screenshot. Page2Images Cons Page2Images offers a limited number of rendering options, all of which are outdated. This also means you can not specify the width and height of your final image. This tool can only generate JPG images, so you must pick a different converter if you need any other file format. ## [Free Convert](https://www.freeconvert.com/html-to-jpg) Free Convert is a complete suite of conversion tools that can also turn HTML code or files into JPG images. You can upload your document from your computer, Dropbox, Google Drive, or simply add the URL of the page you want to screenshot. If you use the tool without creating an account, you will be forced to wait in a queue. It is possible to skip the line with a paid plan. The Basic one starts at $9.99 per month and comes with 1500 conversion minutes/month, which can cover up to 150 GB of data. ![](/content/html-to-image-converters/image1.png) Free Convert Pros Free Convert is extremely easy to use, all you have to do is add your file or URL, and then it will automatically convert it into a JPG. You can configure the viewport width, set up an initial delay, and hide cookie notices. The tool accepts large files (up to 1GB) and can convert multiple URLs or HTML documents at the same time. Free Convert Cons Free Convert can only generate JPG images. Moreover, you can not specify the height of the final image, so all your screenshots will be full page. And even though Free Convert can turn HTML files into images, it was not built specifically for this, which means it lacks certain features available in other converters. ## [Onlineconvertfree](https://onlineconvertfree.com/convert-format/html-to-jpg/) Onlineconvertfree offers a wide range of conversion services. You can render HTML files into multiple image formats, like PNG, JPG, SVG, GIF, PDF and more. The name suggests this tool is free, but to get the most out of it, you must sign up for a paid plan with pricing starting at $8.99 per month. This tool has a 4.8 stars rating from more than 120 people. ![](/content/html-to-image-converters/image3.png) Onlineconvertfree Pros Onlineconvertfree is relatively easy to use and provides various image formats. Onlineconvertfree Cons This tool does not allow you to configure the final image quality and size, plus the HTML converter appears to be in Beta. ## What's the best way to convert HTML to an image? The best way to convert HTML code to an image is by using a converter. Now depending on your needs, you can pick a free online converter or go with something a bit more advanced, which might save you tons of time and money in the long run. Urlbox is one of the most complex but easy-to-use HTML-to-image converters available today. It packs a full suite of features you can leverage to generate high-quality, professional-grade images and PDF documents. ## Best way to convert HTML to image programmatically The best way to convert HTML to image programmatically is by using a [screenshot service API](https://urlbox.com/screenshot-api.md). There are many different options available, so make sure you pick one that works with your stack, and has excellent customer service and uptime. Here are some detailed guides on how to programmatically convert: - [HTML to PNG](https://urlbox.com/automated-screenshots/html-to-png.md) - [HTML to PDF](https://urlbox.com/automated-screenshots/convert-webpage-to-pdf.md) - [HTML to SVG](https://urlbox.com/automated-screenshots/convert-html-to-svg.md). ### How to convert a div into an image You must use a screenshot generator to convert a div into an image, but it needs to have the option to capture a specific Selector. With Urlbox, you can achieve this by simply appending the element's Selector to the request URL or by using the Sandbox mode to quickly generate the exact screenshot you are looking for. ### How to convert a full page into an image You can convert a full page into an image using various tools, like browser extensions, online converters, or [screenshot APIs](https://urlbox.com/screenshot-api.md). Check out this guide that covers all methods to capture a [full-page screenshot](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md). --- # Html2Canvas Alternatives: Comparing The Top 4 Website Screenshot APIs and Libraries > This article compares the top 4 website screenshot APIs and JS libraries you can use to replace Html2Canvas. Source: https://urlbox.com/html2canvas-alternatives Last updated: 2025-03-21 --- Html2Canvas is an excellent resource if you have to set up automatic screenshots, but the web pages are often not rendered accurately. Not to mention the final image quality is lacking. Most people want to switch away from Html2Canvas because of one or more of the following: - it doesn't load iFrames - it usually doesn't render CSS correctly - it doesn't load images hosted on 3rd party domains - it takes a lot of time to set up, configure and debug In this article, I'll share four Html2Canvas alternatives you can start using today to enhance the quality of your screenshots while ensuring that each element of the web page renders as expected. ## Urlbox - Best Html2Canvas Alternative for Growing Businesses Urlbox is a [screenshot service API](https://urlbox.com/screenshot-api.md) built specifically for businesses looking for a fast, reliable way to generate high-quality screen captures. ![image4](/content/html2canvas-alternatives/image4.png) The best part about Urlbox is that it can be implemented in a few minutes regardless of your stack. Here are some examples: - [Python/Django](https://urlbox.com/website-screenshots-python.md) - [PHP/Laravel](https://urlbox.com/website-screenshots-php.md) - [Ruby/Rails](https://urlbox.com/website-screenshots-rails.md) - [Java](https://urlbox.com/website-screenshots-java.md) - [C#](https://urlbox.com/website-screenshots-c-sharp.md) - [Node.js](https://urlbox.com/7-ways-website-screenshots-nodejs-javascript.md) ### Urlbox Features Packing a complete set of features, Urlbox lets you configure how the page will be rendered before you capture the screenshot through a plethora of options: - Block Ads - Urlbox can automatically block ads from showing on the final screenshot - Hide Cookie Banners / Click Accept - You can automatically hide cookie banners or click accept - Retina Quality - Enabling this option will generate a retina-ready image - Proxy - Tunnel the request through any proxy you want - Headers/Cookies - Add custom headers or cookies to the webpage before rendering - Delay - Instruct Urlbox when to capture the screenshot by setting up a delay in ms or on specific events (Dom Load, All Requests Finished, etc.) - Full Page Screenshot Modifications - You can allow infinite scroll, instruct Urlbox to hover over an element, and many more - Custom User Agent - Specify a custom User Agent or pick from the default ones. Moreover, Urlbox provides full [web fonts](https://urlbox.com/webfonts.md) and [emoji](https://urlbox.com/emoji.md) support, correctly captures iFrames, and can even highlight text on the target web page. Once you set everything up you can start converting [HTML to images](https://urlbox.com/html-to-image.md) or generating [images from URLs](https://urlbox.com/url-to-image.md). And you can export in multiple formats ([PNG](https://urlbox.com/url-to-png.md), JPEG, PDF, WEBP, AVIF, SVG, [PDF](https://urlbox.com/url-to-pdf.md), or HTML files). ### Most Common Use Cases Businesses use Urlbox to quickly and reliably generate screenshots. Let's take [CoverageBook](https://coveragebook.com/) as an example. It's a company that helps PR professionals showcase and share the impact of their work online. They serve over 12,000 customers, so they needed a way to generate a few hundred thousand screenshots. They tried building an in-house solution initially, but that left them with significant maintenance and support burdens, which resulted in the need to hire multiple engineers just to keep things running. [Here's what they said](https://urlbox.com/customers/coveragebook.md) after moving to Urlbox: "Using Urlbox, we've scaled our volume to over five times what we were. Millions of screenshots of thousands of websites over the last couple of years. We’re confident that Urlbox will continue to produce great results as we grow." [ReviewTycoon](https://www.reviewtycoon.com/) is another example of a business using Urlbox to capture high-quality screenshots automatically. They help their customers set up review websites. That means that each reviewed website needs a high-quality thumbnail to go along. When they started, they manually added these thumbnails but quickly realized they needed a way to automate the whole process. After trying multiple options, [they concluded](https://urlbox.com/customers/reviewtycoon.md): "It's way more difficult to use other services - it can take 5 minutes to add a review! Thanks to Urlbox, it takes like 10 seconds." Businesses use Urlbox to make their products better and speed up development. You can view more examples of leveraging the Urlbox API [here](https://urlbox.com/customers.md). ### Urlbox Pricing Getting started with Urlbox doesn't cost you anything. You'll get a [7-day free trial](https://urlbox.com/pricing.md) when you first sign up, regardless of your chosen plan. You can pick from one of the four available plans once the trial period ends. Depending on the number of screenshots you need to capture each month, you can go for: - [The Lo-Fi Plan](https://urlbox.com/signup/lo-fi-monthly-a.md): Starting at $19 monthly for 2,000 screenshots, this plan is perfect for generating thumbnails. - [The Hi-Fi Plan](https://urlbox.com/signup/hi-fi-monthly-a.md): Priced at $49 per month for 5,000 screenshots, this plan is best for businesses looking to capture creating pixel-perfect screenshots and retina-resolution images. - [The Ultra Plan](https://urlbox.com/signup/ultra-monthly-a.md): For $99 per month for 15,000 screeenshots, this plan is ideal for advanced web imaging. Urlbox was explicitly built for revenue-generating businesses, so if you are looking for a free or cheaper alternative to Html2Canvas, you should read on. ## GetScreenshot - Html2Canvas Alternative for Small Businesses Much like Urlbox, GetScreenshot is a screenshot service API that allows you to screenshot web pages at scale. ![image3](/content/html2canvas-alternatives/image3.png) ### GetScreenshot Features Although not as powerful as Urlbox in terms of customization, GetScreenshot allows you to: - add custom CSS rules and JS scripts - hide message clients like Intercom, Drift, etc. - highlight specific keywords or full phrases - send your screenshots to a specified email address - bypass logins (although they note this is an experimental feature for now). GetScreenshot lets you save the final image as a JPG, PNG, or PDF file. In addition to the above, it also comes with a Zapier integration and webhooks so that you can send a POST request to your custom endpoint. On the other hand, if you're looking to hide ads automatically, upload your screenshot to an S3 bucket, or use a proxy, you will be better off going for Urlbox. ### GetScreenshot Pricing Pricing plans start at $5 per month (the Lincoln Plan). This allows you to capture up to 2.500 screenshots per month and make five requests per second. Their biggest plan goes for $20 per month, which lets you capture up to 15.000 screenshots and get dedicated assistance in either scripting or Zapier automation setup. You can try GetScreenshot for free for an entire month using their FREE5 code, but this only covers the Lincoln Plan. However, it is possible to use this code to get a $5 discount on any of the other two plans. ## DOM to Image - Html2Canvas Library Alternative to Generate PNGs and JPEGs [dom-to-image](https://github.com/tsayen/dom-to-image).js is a library that can turn an arbitrary DOM node into a vector (SVG) or raster (PNG or JPEG) image, written in JavaScript. ![image2](/content/html2canvas-alternatives/image2.png) It's based on [domvas by Paul Bakaus](https://github.com/pbakaus/domvas) and has been completely rewritten, with some bugs fixed and some new features (like web font and image support) added. ### DOM to Image Features This is a lightweight JavaScript library, so you shouldn't expect too many rendering options (compared to the previously covered APIs). Nevertheless, DOM to Image lets you specify: - the height and width of the rendered web page - increase or decrease the final JPEG quality - change the background color - skip a specified DOM node from rendering - add a fallback option in case an image can not be loaded. ### DOM to Image Limitations DOM to Image is great if you want to screenshot a simple web page, but it struggles with anything fancier, like iFrames, cookie banners, and even lazy loaded images. At the same time, if you need to [convert a webpage to PDF](https://urlbox.com/automated-screenshots/convert-webpage-to-pdf.md), you'll need to find a workaround, as the only output formats currently supported are PNG and JPEG. ## HTML Screen Capture - Html2Canvas Library Alternative to Generate HTML files As the name suggests, this tiny, highly customizable, single-function javascript/typescript library allows you to capture a webpage and returns a new lightweight, self-contained HTML document. ![image1](/content/html2canvas-alternatives/image1.png) The library removes all external file dependencies while preserving the original appearance of the page. At only 12KB, it offers unparalleled speed and peerless reliability. ### HTML Screen Capture Features and Use Cases The main purpose of [this library](https://github.com/html-screen-capture-js/html-screen-capture-js) is to capture a webpage and convert it into a single HTML document that can be displayed as a snapshot in an iFrame. All scripts, CSS classes, and styles are replaced by new in-document classes, plus all image sources are replaced by inlined base64-encoded versions. This is a different approach to screenshots that I found worth mentioning. ### HTML Screen Capture Limitations This library is not for people looking to capture and save screenshots as images. If you want to convert your target web page to PNG, JPEG, or PDF format, then go with the other Html2Canvas alternatives I have covered. ## What Is The Best Html2Canvas Alternative? Choosing the best website screenshot solution depends on your end goal, the stage of your business, and how big your project will get. You should use a lightweight JS library if you are just starting a pet project. On the other hand, if you are tasked with implementing a reliable solution that can capture thousands or millions of screenshots per month, then you should go with [Urlbox](https://urlbox.com/pricing.md). Try it for [free for seven days](https://urlbox.com/pricing.md) (no credit card required), and then decide if it's the Html2Canvas alternative you are looking for. --- # Html2Canvas vs PhantomJS vs Urlbox - A Comparison > This article is a thorough comparison between HTML2Canvas, Phantom JS, and Urlbox, some of the leading website screenshot tools on the market. Read on! Source: https://urlbox.com/html2canvas-vs-phantomjs-vs-urlbox Last updated: 2025-03-21 --- Manually creating a single website screenshot can be a time-consuming and cumbersome process. Now think of generating hundreds, thousands, or even more screenshots, and things get complicated. That's why various tools, libraries, and APIs have been created. When it comes to automated screenshots, you will need a fast, reliable, and easy-to-scale solution. Moreover, depending on the websites you have to screenshot, bypassing ads, cookie banners, captchas, or random popups can be complicated. There are a lot of choices out there when it comes to creating screenshots automatically, but bottom line, the three leading contenders are PhantomJS, Html2Canvas, and URLBox. In this article, I will compare these alternatives so you can make an informed decision on which one to pick for your specific needs. ## Html2Canvas vs. PhantomJS vs. Urlbox - The comparison overview PhantomJS is a headless browser that you can use to screenshot webpages and generate thumbnails. However, its development has been discontinued. Html2Canvas is a JavaScript HTML renderer that takes screenshots based on the DOM. Urlbox is a screenshot automation API that supports almost all browsers out of the box. It works with all popular programming languages, so anyone can use it regardless of the stack they work with. ![](/content/html2canvas-vs-phantomjs-vs-urlbox/image3.png) Automated screenshots are only as good as the person setting up the system. For example, if your automated screenshot system fails to run correctly or is set up incorrectly, it could result in you losing records or, most likely bad quality, unusable screenshots. PhantomJS and HTML2Canvas will work only if the person who sets them up has enough experience with these systems and can quickly debug any possible errors. On the other hand, since they are open source and vastly used, you're most likely to find all the information you need online. You just need time and patience. Another aspect you should pay close attention to is how complex is the layout of the website you're going to screenshot. For example, a basic webpage consisting of only HTML and CSS will load precisely the same regardless of the browser you're using, so taking a screenshot of it is also pretty basic and less prone to errors. Now say you add an extra layer of complexity, like a section featuring display ads generated by a 3rd party service (Adwords), then things might get a bit more complicated. Taking this one step further, if the website in question lazy loads images, has a cookie banner, or displays popups, capturing a screenshot becomes tedious even if you manually do it for a single page. I'm going to consider all these things in the detailed breakdown below. That way, you can make an informed decision and set up the system that works best for your specific needs. ## Urlbox: The best screen capture API for revenue-generating businesses Urlbox enables you to effortlessly create pixel-perfect screenshots of any URL, with various options that can be used to customize the screenshot fully. Urlbox is the most robust screenshot capture solution on the market. It's easy to integrate into your existing application or workflow. It has extensive documentation and official client libraries for Ruby, PHP, Python, [Node.JS](https://www.npmjs.com/package/urlbox), and many more, making it easy to get started. But what really makes Urlbox stand out from the crowd is their Sandbox mode. It's basically a dashboard where you can add the URL you're about to screenshot and configure the way you want it to look. Once you click render, the service will instantly generate the screenshot. ![](/content/html2canvas-vs-phantomjs-vs-urlbox/image2.gif) Besides simply generating a screenshot, the Sandbox automatically generates both a Request URL and your options as JSON. Compared to the other services on this list, Urlbox is the only paid option. However, it comes with a free trial, so you can give it a try before committing to a purchase. Have a look over the [pricing page](https://urlbox.com/pricing.md) to pick the one that best suits your needs. ### Features Urlbox has been developed specifically for revenue-generating businesses, ranging from single freelancers and bloggers to startups and enterprises. Its ease of use and scalability vastly outperform the other services on this list, so if you are looking to get started almost instantly and scale to millions of screenshots per month, then be sure to check us out. ![](/content/html2canvas-vs-phantomjs-vs-urlbox/image1.png) Some features that work out-of-the-box: - full web font and emoji support - generate responsive screenshots - screenshot a specific element on the page - automatic triggering of lazy loading elements - highlight text on the page before taking a screenshot - hide elements on the page before taking a screenshot - set cookies to get around cookie walls and authenticated pages - wait to ensure a specific element is loaded before taking a screenshot - the ability to click on or hover over elements before taking a screenshot - can handle infinite scrolling pages, scroll hijacking, 100% height background images. With such a vast feature set, you might think it's hard to implement everything in a way that works with your stack, but that's not the case since Urlbox is an API. Just play around in the Sandbox to get familiar with all options. ### Who is it for Urlbox works best for businesses and individuals looking for a scalable solution that can automatically generate pixel-perfect screenshots. Here's what [Mike Schauer, the founder of Swiped.co said about](https://urlbox.com/customers/swiped.md) the service: "I was using browser extensions to capture screenshots of websites. I analyzed and organized hundreds of examples of copywriting and marketing promotions - manually processing and uploading each screenshot. Urlbox allowed me to streamline this with a WordPress integration. There are so many screenshot services out there. They're fine if you're just doing thumbnails. You don't care about quality or configuration options. It didn't take me long to find holes and hit the limitations of every one I tried. Urlbox has every feature I've ever needed to take great screenshots every time." [Matthias Wagner, the CEO of Flux](https://urlbox.com/customers/flux.md), used Urlbox to automate the screen capture process for their platform: "We wanted to have something visual when people share their projects on Facebook, Twitter, Slack, and so on. We wanted them to have a nice screenshot of their actual circuit on social media. I set up Urlbox, and I've not had to touch it in many, many months. It would have been so cumbersome to implement a service of our own to take screenshots. Urlbox's API is so straightforward, and the live preview is cool. I can play around with the parameters and see it do what I need it to do." ### Who is it not for As with every other online service, the cost can rapidly increase as you start capturing more and more screenshots. For example, the smallest $19/month plan comes with 2k requests per month. If you will use the screenshots as thumbnails and quality is not one of your primary concerns, then Urlbox might not be for you. ### How to get started with Urlbox The process is straightforward. First, you'll have to go to the [pricing page](https://urlbox.com/pricing.md) and pick the plan that works best for you. Add your details to create an account, and you're good to go. ## Html2Canvas: The best HTML to PNG converter for simple projects Html2Canvas is a JavaScript library you can use to take a screenshot of a whole web page or a specific part. To get started with it, you'll have to download the library from [Github](https://github.com/niklasvh/html2canvas) and include the html2canvas.js script at the \<head> of the page you want to capture. The screenshots taken by this library are based on the DOM and, as such, may not be 100% accurate to the real representation. Keep in mind that Html2Canvas doesn't take an actual screen capture but builds the screenshot based on the information available on the page. Since it does not require any rendering from the server, the whole image will be created on the client's browser. So if you are looking to bypass popups, captchas, or any other dynamically generated content, you might want to try a different service. ### Who is it for Html2Canvas is great for people looking for a lightweight and straightforward JS library that can take screenshots directly from the client's browser. ### Who is not for Html2Canvas is still experimental, so it's not recommended for big projects. Even though installing the library can be fast, configuring everything you need and scaling can be cumbersome. ## PhantomJS: The best HTML5 to JPEG converter for old school coders PhantomJS is a headless web browser scriptable with JavaScript. Among other features, it allows you to capture web contents, including SVG and Canvas, programmatically. IMPORTANT: Its development has been suspended since 2018, so I highly recommend you either migrate to another service or start with another option for your project. Since PhantomJS was such a popular headless web browser, StackOverFlow is full of answers you can skim through to get almost any information you need. On the other hand, this can mean lots of time spent trying to get it working just the way you like. Moreover, as browsers and code evolve, you'll find yourself forced to migrate to a service that can keep up with these changes sooner rather than later. ### Who is it for PhantomJS is great for people that already have it up and running and use it for network monitoring or website testing. ### Who is not for PhantomJS is not recommended for large projects that need to scale or businesses looking to implement a screen capture service from scratch. ## Html2canvas vs PhantomJS vs Urlbox - Final considerations Picking the right screen capture service can be a cumbersome process, so here's a quick breakdown of each service based on who is it for: 1\. Urlbox - the best screen capture API for revenue-generating businesses. If you want to get started quickly, prepare to scale, and generate pixel-perfect screenshots, this is for you. 2\. Html2canvas - the best HTML to PNG converter for simple projects. If you want to capture simple screenshots directly from the DOM, this JS library is for you. 3\. PhantomJS - the best HTML5 to JPEG converter old school coders. Implementing its screen capture functionality should be a breeze if you are already using PhantomJS as a headless browser. When going for one of these options, you have to think in advance and ideally write down all the functionality you need. Then reread the article and mark down the service that checks all the boxes. The more features you need, the closer you'll get to picking Urlbox as your screen capture service. After all, it is the most comprehensive of them all. Not only that, but businesses of all sizes are using Urlbox as their go-to [screenshot API](https://urlbox.com/screenshot-api.md). Here are just a few [testimonials](https://urlbox.com/customers.md) from them. Check out all its features and different pricing plans [here](https://urlbox.com/customers.md) and get started today. --- # 5 MirrorWeb Alternatives for Website Archiving > Explore five MirrorWeb alternatives for website archiving: Urlbox, Stillio, PageFreezer, Wayback Machine, and Archive.today. Source: https://urlbox.com/mirrorweb-alternative Last updated: 2023-04-19 --- In the ever-evolving digital landscape, [website archiving](https://urlbox.com/website-archive-tools.md) has become a crucial practice for businesses of all sizes. With stringent compliance regulations and the need for accurate historical records, archiving web content and social media profiles is no longer just a matter of convenience—it's necessary. Safeguarding your online presence ensures you stay on the right side of the law while preserving your digital legacy. Archiving your website and social media profiles can also serve as a valuable resource for understanding the [evolution of your online presence](https://urlbox.com/online-reputation-monitoring.md), analyzing trends, and maintaining a consistent [brand image](https://urlbox.com/brand-monitoring-tools.md). As your business grows and evolves, this digital record can provide invaluable insights into your past strategies and the effectiveness of various campaigns. Furthermore, archiving can protect you from potential legal disputes, as [archived content](https://urlbox.com/social-media-archive-tools.md) may serve as evidence to support your claims or refute false accusations.

In this article, we'll explore five MirrorWeb alternatives for website archiving: Urlbox, Stillio, PageFreezer, Wayback Machine, and Archive.today. We'll take a look at their key features, reviews, pricing and how they work. ## What is MirrorWeb MirrorWeb is a powerful web archiving platform designed to help businesses preserve and manage their digital presence by creating web archives.

Urlbox is a comprehensive screenshot service API that helps businesses capture snapshots of any URL. It offers three different render modes—Viewport, Element, and Full Page—allowing you to capture screenshots and generate an archive tailored to your needs. For example, the [Full Page render mode](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md) works great for webpages featuring extensive information, like the Terms and Conditions page. On the other hand, the Element render mode is better used to capture a social media post or the comments section. There are various ways you can leverage Urlbox to create a web archive: - Via API: You can integrate Urlbox into your existing app or website regardless of your tech stack or simply use the REST API capabilities to automatically generate screenshots of any website with a single request URL. - Using no-code tools: Urlbox provides a Zapier connector allowing you to set up advanced workflows without writing a single line of code. - Manually via Dashboard: You can try Urlbox by generating a screenshot directly from your Dashboard. Even if this is a manual process, you can use a spreadsheet tool, like Excel or Google Sheets, to generate Request URLs in bulk and then save the screenshots to your local machine archive. You can [try Urlbox for free](https://urlbox.com/pricing.md) for seven days, regardless of your chosen plan. After that, you can [upgrade to a paid plan](https://urlbox.com/pricing.md) with pricing starting at $19 per month. This includes up to 2,000 screenshots per month and allows you to make up to 30 requests per minute, which means you can capture a screenshot every 2 seconds. Urlbox also provides plans suited for enterprises. For example, the [Ultra Plan](https://urlbox.com/pricing.md) starts at $99 for 15K screenshots and scales to $3,500 if you need to capture 10,000,000 screenshots per month. You will also get all features and enjoy early access to new features. ## Stillio ![](/content/mirrorweb-alternative/image3.png) G2 rating: [4.9 out of 5 stars](https://www.g2.com/products/stillio/reviews) Key features: - Automated screenshot capturing: Schedule regular, automated screenshots of websites and web pages to track changes and create web archives. - Downloadable screenshots: Easily download screenshots for printing or save archive data to Dropbox as needed. - Customizable screenshot titles: Automatically create readable and easily accessible titles for your screenshots. [Stillio](https://urlbox.com/stillio-alternatives.md) is a web archiving tool designed to help businesses create web archives through automated screenshots. It is beneficial for monitoring competitors, tracking search engine rankings, and maintaining a visual history of a website's appearance. The platform's user-friendly interface helps you quickly set up the archiving process and makes navigating and managing archives a breeze. Even so, there are a few limitations to consider before choosing Stillio. As it primarily focuses on screenshot-based archiving, it may not provide comprehensive archiving solutions for businesses with more extensive needs. The platform also lacks built-in support for social media archiving, which could be a crucial feature for some users. Stillio offers a 14-day free trial, after which you must upgrade to a paid plan with pricing starting at $29 per month. The Snap Shot plan allows you to screenshot up to 5 webpages daily. The Top Shot plan starts at $299 and allows you to screenshot any number of web pages every 5 minutes. ## PageFreezer ![](/content/mirrorweb-alternative/image4.png) G2 rating: [4.5 out of 5 stars](https://www.g2.com/products/pagefreezer/reviews) Key features: - Automated website archiving: PageFreezer's crawling technology takes snapshots of your website, automatically capturing new web pages and changes to existing ones. - Defensible legal evidence: Provides trusted, non-refutable evidence complete with metadata, timestamped with an SHA-256 digital signature, and exportable in PDF and native formats. - Advanced capture capabilities: Supports archiving client-side generated webpages using Javascript/Ajax frameworks, web form flows, and content displayed after user events. PageFreezer is a robust web archiving solution designed to help businesses create and maintain web archives for compliance, legal, or historical purposes. With its automated archiving, advanced capture capabilities, and powerful search functions, PageFreezer is a valuable tool for organizations requiring comprehensive and reliable website archiving. However, PageFreezer is more complex and feature-rich than most businesses need. If that's your case, you might be better off with another MirrorWeb alternative. ## Wayback Machine ![](/content/mirrorweb-alternative/image1.png) G2 rating: N/A Key features: - Existing archive: Wayback Machine provides access to historical records of billions of web pages. - Website change tracking: Monitor changes to a website's structure and creatives, including CSS, HTML, and JavaScript. - No setup needed: Wayback Machine works by itself, so you don't have to set up anything. However, this can also mean it might not archive your website. [Wayback Machine](https://urlbox.com/wayback-machine-alternatives.md) is a digital archive of the World Wide Web, allowing users to access historical records of web pages. Businesses can utilize the Wayback Machine to keep track of competitors, back up website content, monitor website changes, and mitigate link rot and broken links. The biggest downside of Wayback Machine is that you can’t configure its frequency. This means you cannot rely on it to capture daily screenshots of your website. In addition, it can not archive social media posts, so if that's something you need, you must go with a different MirrorWeb alternative. Wayback Machine is free to use and publicly available to anyone. ## Archive.today ![](/content/mirrorweb-alternative/image5.png) G2 rating: N/A Key features: - Request-based archive: Archive.today can capture individual web pages upon user request, providing a snapshot of content at a specific time. - Archive code: Archive.today preserves HTML class names within the old-class attribute. - It does not rely on robots.txt: Archive.today enables archiving of web pages unavailable on other free services like the Wayback Machine.

Remember that this tool does not capture non-static content such as XML, RTF, and spreadsheets, which may be an essential requirement for some businesses. There is no built-in support for social media archiving, which can be a crucial aspect of web archiving for many organizations. Archive.today is free to use, making it an excellent choice for small businesses looking to keep a simple archive of their website. ## Try Urlbox to create web archives Monitor your competitors, track your online presence, capture your website's historical records, or generate archives of virtually any webpage with Urlbox.

Source: https://urlbox.com/monitor-copyright-infringement Last updated: 2023-10-12 --- The protection of your intellectual property, like written content, images, and logos, is critical to your reputation as well as your income. With so much copying and sharing happening online, it's vital to have the right tools to guard your work. In this article, we'll dive into the importance of monitoring your intellectual property and cover four tools that can help you protect against thieves. ## What is the most common copyright infringement? Copying text and images from other sources is the most common form of copyright infringement in the digital space. Beyond the evident legal risks, this practice poses significant SEO challenges. Search engines devalue sites with duplicated content, often pushing them down in search rankings, which can greatly influence a business’s bottom line. But consequences extend even further. Stolen copyrighted content can pose a great risk to a [brand’s reputation](https://urlbox.com/brand-monitoring.md), as it can often appear unoriginal or untrustworthy to its audience. This lack of authenticity can lead to reduced user engagement, diminished trust, and potential loss of business or clientele. Similarly, the unauthorized use of copyrighted images further compounds the issue. Not only do search engines penalize sites for using widely distributed images, but businesses can also face legal actions from the original copyright holders. Such infringements can result in hefty fines and damage the public's perception of a brand. Even so, bad actors or unknowing businesses will always copy text and images from the web and use them as their own. And the only way to protect your assets and intellectual property is by monitoring copyright infringement. ## How do you detect copyright infringement? Here are a few ways to detect copyright infringement: 1. Manually. You can either regularly search for key phrases or titles from your content on popular search engines or use tools like Google’s Reverse Image Search to look for copies of your content by uploading or linking the original. 2. Digital watermarking. Insert watermarks on your images or videos. If they're used elsewhere without permission, these watermarks can help trace back to the original source. 3. Using CMS. Many CMS platforms offer plugins or extensions that automatically scan and notify you of potential copyright infringements. 4. DMCA. Companies like [DMCA.com](https://www.dmca.com/) offer protection services that monitor and send takedown notices on your behalf if they detect unauthorized use of your content. 5. Metadata analysis. By embedding metadata within your digital files (like author name, creation date, and copyright details), you can prove ownership if the need arises. Tools can then scan the web to ensure that this metadata hasn't been stripped and used without permission. While no method guarantees complete protection, a combination of the above strategies can reduce the risk of infringement. You can start by watermarking and adding metadata to your images and videos, but things get complicated when it comes to monitoring text. ## Best Tools for Monitoring Copyright Infringement Here are the best tools you can use to monitor and protect yourself against copyright infringement when it comes to videos, images, and text. ## Copyscape [Copyscape](https://www.copyscape.com/about.php) is one of the industry’s leading tools and helps protect your intellectual property online. To fully leverage this tool, you should upgrade to their premium version – Copyscape Premium – as it gives you the ability to check the originality of copy-paste text and offers support for PDF and Word file uploads. This premium service also offers a batch search function, a private index, and case tracking. For developers, the Copyscape API can be integrated into your existing content management systems to automatically scan and check the originality of the content you’re about to publish. Besides the Premium service, Copyscape also provides Copysentry, which scans the web daily or weekly and sends you email alerts if it finds any copies of your published content. This is an excellent tool for those who want ongoing, automated monitoring to ensure that their intellectual property remains secure online. ## Google Alerts [Google Alerts](https://www.google.com/alerts) is an easily accessible tool that allows you to monitor the web for new mentions of specific keywords, phrases, or entire sentences. For businesses concerned about copyright infringement, setting up Google Alerts is the easiest way to keep tabs on where and how your content is being used across the Internet. Among the best features of Google Alerts is its flexibility and granularity in setting up alert conditions. You can specify the types of web pages you want the service to monitor, whether it’s news articles, blogs, or forums, providing you with targeted insights into where your content may be appearing without your consent. You can also choose the frequency of notifications, giving you the power to respond to potential copyright infringements right away. Although Google Alerts might not have the same coverage as specialized plagiarism detection services like Copyscape, it’s an excellent additional tool to use. ## Oxylabs Compared to Copyscape or Google Alerts, [Oxylabs](https://oxylabs.io/solutions/brand-protection-industry/copyright-infringement) is an advanced solution for businesses that need to consistently scrape the internet for copied content at scale. It allows you to find copyright infringements globally and gives you the ability to sweep platforms like Amazon, eBay, and Google Shopping to track and gather necessary evidence of your content or product listings being stolen. For instance, its e-commerce scraper API retrieves real-time and highly localized public product data from most e-commerce sites. With Oxylabs’ Web Crawler feature, you can crawl any website to discover and index all or specific URLs, which can then be monitored for copyright infringement. For gathering conclusion evidence against infringers, you can use Oxylabs in conjunction with tools like Urlbox, which allows you to take screenshots of the pages where copied content is found, providing irrefutable proof for legal proceedings. This becomes particularly important when dealing with JavaScript-heavy websites where simple text scraping might not capture the full content. ## Urlbox Urlbox is a screenshot service API that can render virtually any webpage or HTML file and generate an image you can archive. It works with all major programming languages and has a native Zapier connector, but you can also use it by making a REST API call. One of the significant advantages of Urlbox is its compatibility with other monitoring tools like Google Alerts and Oxylabs. By setting up an automated system that integrates these services, you can have Urlbox take screenshots immediately when an alert for potential copyright infringement is triggered. This creates a two-fold benefit: you are notified about the infringement and equipped with the visual evidence needed to take immediate action. ### Use Urlbox to archive your web pages One of the biggest hurdles in a copyright dispute is demonstrating beyond doubt that you were the initial creator of the text and images that appear on someone else's website. Services like [Wayback Machine](https://urlbox.com/wayback-machine-alternatives.md) are constantly archiving webpages, but the frequency with which these crawlers browse your website is beyond your control. This is exactly why you should create your own [website archive](https://urlbox.com/website-archive-tools.md). One of the best ways to protect your intellectual property is to convert and save all your web pages as images or PDF files. You can use Urlbox to capture screenshots at specific time intervals and upload them directly to Amazon S3. You can also configure Urlbox to automatically retake a screenshot when something changes on a webpage by connecting it with other apps. But you can use Urlbox for much more, as there are two sides to copyright infringement. ### Use Urlbox to gather proof of copyright infringement Stolen content can greatly affect your business, especially if someone steals it from you. As mentioned before, bad actors can use your text and images as their own, which can cause major SEO issues, influence how people feel about your brand, and potentially decrease your business’s bottom line. When you discover that someone is using stolen content from your website, you can always ask them to remove it. But if you’re looking to pursue legal action, then you must keep evidence. And, one of the best ways to do so is by using a tool like Urlbox to automatically screenshot a webpage that has been flagged. You can do so by connecting Urlbox with other monitoring tools either via Zapier or API so it can immediately capture a snapshot of the page that contains your intellectual property. ## What is the best tool to monitor copyright infringement? While you can rely on Copyscape or Oxylabs to monitor copyright infringement, there might be some instances when these tools miss out on subtle instances of content replication or alteration. It's also possible for certain web pages or platforms to be beyond their scanning reach, leading to potential blind spots in your monitoring efforts. Therefore, it's essential to integrate multiple tools and regularly update your monitoring strategies if you want to be sure that you’ll protect your intellectual property. And the first step you should take is to archive your web pages.

Source: https://urlbox.com/monitor-search-engine-rankings Last updated: 2025-03-21 --- If search engine optimization (SEO) feels like black magic, you’re not alone. But there’s a method to the madness, and we’ll show you how to keep tabs on your rankings to crack the code. Most people know about keyword research and tracking — but that’s just one piece of the puzzle. The proof is in the pudding — does the keyword you target gets you to the top of search engine results pages (SERPs)? That’s where SERP monitoring comes in to ensure your SEO and keyword strategy is indeed effective in helping you gain visibility and drive traffic. It tracks how your site ranks for specific keywords minute-to-minute within the context of relevant search results. Let’s look at how SERP monitoring and keyword tracking complement each other to support effective SEO. ## What are SERPs? A SERP is the page you see after entering a query into a search engine. It contains the top web pages or properties the algorithm considers relevant to your search. There are different types of results on a SERP, including organic search results, paid ad results, video results, knowledge graphs, maps, and featured snippets. ### The Importance of Monitoring SERPs Monitoring SERPs helps you understand your website’s SEO performance and improve your rankings for relevant search terms so more high-quality prospects can find your business. Seeing how search results appear on a SERP can also help you target keywords with SERPs that have fewer ads and features. But why is that important? For example, users are less likely to click on your link if the SERP already displays a zero-click answer (e.g., a featured snippet.) Meanwhile, SERPs with many ads leave less space for organic results at the top — with most traffic coming from the [top 3 positions](https://searchengineland.com/google-continuous-scroll-desktop-organic-search-data-393476) and only 4% of total clicks occurring after position 6, you don’t want to be crowded out. Additionally, tracking SERPs allows you to identify trends in search behaviors and see which topics are most popular among your target audience. The insights can inform your content strategy and make your website more relevant to your ideal customers. If your rankings drop, you can react quickly to adjust your strategy, such as reviewing keyword rankings, adapting your content to algorithm updates, fixing broken links, and removing outdated content. You can also identify your competition by tracking sites that rank well for your target keywords. You can analyze their content and performance to see how you can improve your website’s SEO and increase your visibility. The bottom line: No matter how sound your keyword strategy seems, you won’t get many clicks if your site doesn't appear at the top of search results. ## What Is the Difference Between Monitoring SERPs and Tracking Keywords? “I’ve been tracking keywords, isn’t that enough?” you may wonder. SERP monitoring and keyword tracking are different, and you should be doing both. SERP monitoring involves tracking how your website ranks for specific keywords and appears in search results. You can see if searchers are likely to see your link, if zero-click features may impact your click-through rates, and which sites you’re competing against. On the other hand, keyword tracking involves understanding the search volume for specific keywords. It shows how popular a keyword is and how often people search for it. The insights can help you balance cost, popularity, and competitiveness to identify the most effective keywords for your SEO campaigns. SERP monitoring and keyword tracking can help you target the right keywords, increase visibility, and drive high-quality traffic to your website. ## The Best Keyword Tracking Tools A robust keyword tracking tool can help you identify the best keywords for your content and marketing campaigns. You can track the keywords’ performance, identify trends, monitor your competitors’ rankings, and uncover new growth opportunities. Here are the top tools to use: ### Google Search Console ![image3](/content/monitor-search-engine-rankings/image3.png) The web-based tool measures a website’s search traffic and performance. The insights can help you resolve issues promptly to prevent your search engine ranking from sliding. Also, it allows developers to monitor and address common SEO issues as they code a website. This easy-to-use free tool integrates with other Google products, such as Google Trends, Google Analytics, and Google Ads, to support marketing analysis. Since the application gets data straight from the source, it's the most accurate keyword-tracking tool. However, you can’t use Google Search Console for competitor analysis. Some users find it time-consuming to generate reports and find the data they need. You must also verify your website before accessing the tool. ### Ahrefs ![image2](/content/monitor-search-engine-rankings/image2.png) Ahrefs is an all-in-one SEO tool for keyword and competitor research. It offers ideas for relevant keywords and helps you find the best opportunities to rank high in SERPs. You can also track your site’s ranking alongside your competitors. Ahrefs boasts a database of 8 billion keywords and 421 billion indexed pages. It has an intuitive user interface with plenty of features, such as link building, website audit, content research, and mention monitoring, to help you manage your SEO campaign in one place. Additionally, you can connect it to Google Search Console for free. However, the basic plan costs $99/month, and the advanced plan costs $399/month — it can get expensive if you want access to all the features and functionalities. Some users find the reports hard to interpret and the data inaccurate for keywords with low search volume. ### Semrush ![image4](/content/monitor-search-engine-rankings/image4.png) Semrush offers over 55 online visibility management products and add-ons, including tools for search, content, social media, and market research. It integrates with Google and task management applications to help streamline workflows. The platform monitors over 800 million unique domains and 21 billion keywords for 142 geo databases. Some users report that the data is more accurate than Ahrefs. You can use its features to support SEO, content marketing, competitor research, PPC, social media marketing, and more. However, some people find the platform hard to use and expensive — the Pro plan costs $119.95/month, and the Business plan is $449.95/month. Like Ahrefs, the results are only accurate for keywords with a high search volume. It also has a limited local keyword database. ## Best SERP Monitoring Tools A SERP monitoring tool shows you what a SERP looks like for a specific search term or phrase.

If your goal is to ensure your website is compatible with all browsers and optimized for mobile, GetScreenshot is a good option. However, if you're more focused on monitoring your website for errors and performance, Pagescreen is more appropriate. Monthly subscription plans for GetScreenshot start at $5 per month. But, if you need the Zapier integration, you'll need the $10/month plan or higher. They also offer one month free off the cheapest plan with code FREE5. ## Visualping G2 rating: [4.0 out of 5 stars](https://www.g2.com/products/visualping/reviews) ![image3](/content/pagescreen-alternatives/image3.png) Key features: - Webpage monitoring: Visualping helps monitor any webpage to track price changes, availability of products, and updates on news articles or blog posts. - Frequency and selective monitoring: With Visualping, you can choose the frequency of checks and specify specific areas or elements of a web page to monitor. - Integration with other tools: Easily integrate Visualping with tools like Slack, Trello, and Zapier to streamline workflow and enhance productivity.

You can track multiple websites and select which alerts you want to get pinged about via Slack, Teams, API, and more.

Its simple, intuitive interface is easy for anyone to use. With Pagescreen, users need some technical expertise to get the most out of the tool. Additionally, Visualping provides a broader range of monitoring options than Pagescreen, including the ability to monitor specific sections of a web page or track changes to images. If you're new to screenshot tools, Visualping has a free option with minimal features to practice on. But you must jump two tiers to the $25/month option if you want email support.

Look no further. In this article, we explore the top Restpack alternatives for website snapshots. Source: https://urlbox.com/restpack-alternatives Last updated: 2025-03-21 --- Restpack powers three different APIs that do almost the same thing. They take an URL or bare HTML file and turn it into an image. Now depending on what file extension you are looking for (PDF, JPEG, PNG, etc.), you'll need to sign up for one of their services. What's interesting about this approach is that you can use the Restpack Screenshot API to generate PDF files, but you won't be able to style them. On the other hand, the Restpack HTML to PDF API lets you configure how the PDF is rendered, but it doesn't allow you to export the screenshot in any other format. This means you will need to use both APIs to convert the same webpage into a professional PDF and JPEG image. This might not be a problem for some people, but it can overcomplicate development for others. In this article, I will share 3 Restpack alternatives for pixel-perfect website snapshots and help you pick the right one. ## What to look for when picking a Restpack alternative When switching from Restpack to another service, you must ensure that your new API is easy to implement and works with your stack. Besides the basic requirements, your new API should: - Allow you to configure the viewport settings - Export the screenshot in multiple formats - Capture specific page elements - Capture [full-page screenshots](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md) - Allow you to inject JS & CSS - Generate Retina images - Support lazy loading - Support Webfont - Support CDN These functionalities come by default with most [screenshot APIs](https://urlbox.com/screenshot-api.md), but some Restpack alternatives can do even more. ## Urlbox - Best Restpack alternative for businesses Urlbox is a screenshot service API built for serious businesses. It's easy to use, has detailed documentation, and has excellent support. ![image2](/content/restpack-alternatives/image2.png) ### Urlbox Features Urlbox packs all the features you can find in Restpack, plus some more: - automatically hide cookie banners (or click "accept") - automatically block ads - hide specific selectors - geolocation settings - export to S3 - highlight words - additional export formats (SVG, WEBP, AVIF) The best part is that you won't have to switch between 2 different APIs if you want to [convert a webpage to PDF](https://urlbox.com/automated-screenshots/convert-webpage-to-pdf.md) and JPEG. Moreover, you can start using Urlbox in a few minutes regardless of your stack, as it works with all major programming languages (check out the [documentation](https://urlbox.com/docs.md)). ### Urlbox Pricing The cheapest [plan](https://urlbox.com/pricing.md) goes for $19/month and lets you capture up to 2,000 screenshots per month. Any additional request will cost you $0.01. However, you can try Urlbox for free by signing up for the [7-day free trial](https://urlbox.com/pricing.md) (no credit card required). If you are looking for a bigger volume, you might be better off going for the [Ultra plan](https://urlbox.com/pricing.md). It starts at $99/month for up to 15k requests per month. Not to mention you'll also get priority support. ## ScreenshotAPI - Great for personal projects Next on the list of Restpack alternatives is ScreenshotAPI. It doesn't have the same feature set as Urlbox, but it can help you set up automatic screenshots. ![image3](/content/restpack-alternatives/image3.png) ScreenshotAPI Features As you can expect, ScreenshotAPI comes with most of the basic features you would expect from a screenshot API: - it blocks Ads and Cookie Banners - it supports 4k and 5k Retina Resolution - it lets you set up custom headers and cookies - it allows you to export the final screenshot as a PNG, JPEG, WEBP, or PDF. As a drawback, ScreenshotAPI doesn't come with all the features you need to style a PDF. For example, you can not use it to specify the document's margins, DPI, CSS Media, or even change the orientation. If you believe that is something you might need in the future, you'd be better off with another alternative on this list. ScreenshotAPI Pricing For $9/month, you can get the Essentials plan that lets you capture up to 1,000 screenshots and block ads and cookies. However, if you need to generate Retina images, you'll need to upgrade to the Startup plan. It goes for $29/month and lets you capture up to 10,000 screenshots per month. Paying yearly will get you two months for free on all plans. ## Screenshotlayer - Free to use screenshot API Screenshotlayer is the only API in this list that comes with a free plan. Even so, it's heavily limited to just 100 screenshots per month, but it can work for individuals looking to create basic projects, like small portfolio websites. It's also important to mention that the free plan has a rate limit of 2 requests per minute. ![image1](/content/restpack-alternatives/image1.png) Screenshotlayer Features Screenshotlayer is great if you're looking for simple functionality. It comes with a complete set of basic functionalities: - inject CSS - setup capture delay - change the HTTP User-Agent Headers - export your screenshot to AWS S3 or FTP . On the other hand, it only supports three output formats - PNG, JPEG, and GIF. So if you are looking for PDF export, you'll be better off going with: - Urlbox for advanced PDF exports - ScreenshotAPI for basic PDF exports. Also, Screenshotlayer doesn't block ads or hide cookie banners by default. Screenshotlayer Pricing The main reason I added Screenshotlayer to this list is their free forever plan. Their paid plans start with the Basic Plan for $19.99/month. This plan lets you capture up to 10,000 monthly snapshots and comes with 256-bit HTTPS encryption, unlimited technical support, and ten dedicated workers. You must go with the Professional Plan if you need to upload your screenshots to S3 or FTP. This goes for $59.99/month and lets you capture up to 30,000 monthly snapshots. ## Conclusion - What's the best Restpack alternative? The alternatives I presented above tick all the boxes regarding basic functionality. Ultimately, it all boils down to: - the render quality - the export formats you are looking for - the number of screenshots you need to generate monthly. If you are looking for a screenshot API for a small personal project, you should use Screenshotlayer or ScreenshotAPI. On the other hand, if you are looking for a complete solution that also lets you export professionally formatted PDF files, then you will be better off with Urlbox. It's not only completely [free to try for the first seven days](https://urlbox.com/pricing.md) regardless of the plan you choose, but it also has stellar support to help you get started in no time. --- # The Best 6 Screenshot Guru Alternatives for Automated Screenshots > Discover 6 Screenshot Guru alternatives you can use to capture screenshots automatically.

Moreover, its functionality is limited to the browser it is installed on, which might not be suitable for users who need to capture screenshots across different devices or platforms.

We've got you covered! Here's the full list of the most reliable screenshot APIs. Source: https://urlbox.com/screenshot-machine-alternatives-full-page-screenshots Last updated: 2025-03-21 --- Screenshot Machine is a screen capture API most commonly used by developers looking for an efficient, streamlined way of capturing screenshots automatically. Even though it's easy to configure and works with all major programming languages, Screenshot Machine comes with some limitations: - The output format of the final image can be either JPG, PNG, or GIF. Sure, you can use their Website to PDF API, but then you'll have to write additional code - Currently, it does not have flexbox support. This might not seem significant but remember that more and more websites use this kind of CSS styling, so if you want to build something future-proof, you have to consider this - It does not support Lazy Loading, which is perhaps one of the most significant downsides of this API. These limitations can make or break a great product, so if you are looking for a better Screenshot Machine alternative to capture high-quality screenshots, keep reading. ![](/content/screenshot-machine-alternatives-full-page-screenshots/image3.jpg) ## Urlbox - Best Screenshot Machine Alternative for Serious Businesses Urlbox is an API that helps businesses capture ultrafast, accurate screenshots at scale. It's packed with all the features you may need to generate high-quality screenshots of any website or SPA, regardless of the language or framework it was built with. ![](/content/screenshot-machine-alternatives-full-page-screenshots/image4.png) **More output formats than Screenshot Machine** As previously mentioned, Screenshot Machine lets you export your screen captures in 3 formats, but sometimes that is not enough. With Urlbox, you can render any URL (or HTML & CSS) as JPG, PNG, PDF, AVIF, and even WebP or SVG files. This speeds up your development time while ensuring your images will be compressed and ready to use in next-generation formats, out-of-the-box. **More blocking options than Screenshot Machine** Sometimes you need to capture the contents of a webpage featuring tons of ad banners or popup ads. Urlbox will hide these ads by simply appending the *block\_ads=true* parameter to the request URL. Moreover, you can even hide cookie banners or automatically accept them with built-in parameters. **Better full-page screenshot options compared to Screenshot Machine** Full-page [screenshots](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md) are prone to render errors usually caused by sticky elements, infinite scrolling functionality, and even Lazy Load images. It takes time to set up the configuration to generate a correct full-page screenshot of a single webpage, so if you need to scale to tens or hundreds, you'll most definitely find yourself stuck on a never-ending loop. This is another area where Urlbox shines compared to Screenshot Machine, as the API comes with built-in features designed explicitly for full-page screenshots. It tackles Lazy Load images by default, allows you to enable infinite scroll, and even specify the scroll increment and delay. All these options drastically increase the development speed and ensure your screenshots look precisely as they should. **Pricier than Screenshot Machine** Urlbox is more expensive than Screenshot Machine. The [started plan](https://urlbox.com/pricing.md) will set you back $19 per month in exchange for 2,000 requests per month. On the other hand, Screenshot Machine pricing costs approximately $10 per month and lets you capture 2,500 screenshots. Additional screenshots go for $0.004 each. **The additional cost of Urlbox can be justified only if you are looking for a comprehensive screen capture API that can tackle virtually any webpage.** To get a feel of how Urlbox works and look over all the features I described earlier, you can start a [seven-day free trial](https://urlbox.com/pricing.md) (no credit card required). If that doesn't work for you, keep reading for the other alternatives in this list. ## ScreenshotAPI - Robust Screenshot Machine Alternative Another alternative on this list is ScreenshotAPI, a robust screen capture API that overcomes most Screenshot Machine limitations. As Urlbox, it comes with an integrated Query Builder dashboard you can use to test its features before you start working on your project. ![](/content/screenshot-machine-alternatives-full-page-screenshots/image5.png) ScreenshotAPI lets you export the final image in four formats: PNG, JPEG, WEBP, and PDF. You'll need to set up an extra conversion system if you need any other format. It also lets you block ads, hide cookie banners and enable Lazy Loading. Among all these features, it also lets you configure the way the webpage you're trying to capture looks like through a variety of different options: - force dark mode - scroll to a certain element - change the headers and set up cookies. ScreenshotAPI is also pricier than Screenshot Machine. Their cheapest plan, Essentials, starts at $9 per month and allows you to capture up to 1,000 screenshots. Any additional screen captures will cost you $0.009 each. Their Business plan goes for $175 per month and lets you screenshot up to 100,000 pages. It also comes with priority live chat support, something that's exclusive to this plan. ## APIFlash - Basic Screenshot Machine Alternative APIFlash is a screen capture API based on Google Chrome and AWS Lambda, which uses Chrome to render the webpage before it captures the screenshot. ![](/content/screenshot-machine-alternatives-full-page-screenshots/image1.png) Like the other [screenshot APIs](https://urlbox.com/screenshot-api.md) I covered in this list, APIFlash comes with all the basic functionalities you need to generate a good screenshot: - hide cookie banners and ads - scroll through the entire page - change the User-Agent to emulate a particular device - set additional JS or CSS code before capturing the screenshot. As a drawback, APIFlash only lets you export the final image in 3 formats, PNG, JPEG, or WebP. So if you need to [convert a webpage into PDF](https://urlbox.com/automated-screenshots/convert-webpage-to-pdf.md), you're better off with the other services I presented. Nevertheless, this API is amongst the cheapest, with plans starting at $7 per month for 1,000 screenshots. I find it important to note that this plan comes with basic support. If you think you might need help getting started or using their service, then you'd be better off with the Medium Plan for $35 per month. In addition to the 10,000 monthly screenshots, you'll also enjoy priority support. ## Thum.io - Cheapest Screenshot Machine Alternative Last but not least is Thum.io, a screenshot API focused on thumbnails. I felt like I had to include it in this list as it is the cheapest option on the market. ![](/content/screenshot-machine-alternatives-full-page-screenshots/image2.png) Their pricing plans start at $1 per month, letting you capture 5,000 screenshots. This is crazy cheap, but as you might expect, it doesn't pack the same features as the other alternatives I covered. Now they do have a more advanced plan that goes for $20. Besides the massive 200,000 screenshots covered in this plan, you will also be able to adjust the viewport and capture full-page screenshots. You can go for this API if image quality is not on top of your list of preferences or if you simply need thumbnails and nothing more. ## The Best Screenshot Machine Alternative Picking the right alternative depends on your business goals and what you are trying to achieve by using a screenshot API. Think of the features you will use the most and compile a list. Based on that, you can go with the service that ticks all the boxes. If time is of the essence and you need to switch up fast to the most robust screenshot API, then you should go with Urlbox. Packing all features you might expect from an API (plus some), Urlbox works great regardless of your business type, the programming language you code in, and even your final goals. People [all over the world](https://urlbox.com/customers.md) use Urlbox to generate high-quality screenshots at scale. So go ahead and start your [7-day free trial](https://urlbox.com/pricing.md) today to discover everything Urlbox can do for you and your business. --- # Best Tools to Screenshot Multiple URLs in Bulk > Find the best tools to screenshot multiple URLs in bulk regardless of your tech stack.

Some tools may also provide options to capture specific elements, such as text, images, or CSS selectors. 6. Pricing and support - check the pricing and support options of the tool. Some tools offer free trials or freemium plans, while others require a subscription or one-time payment.

Source: https://urlbox.com/social-media-archive-tools Last updated: 2025-03-21 --- Most businesses archive social media posts and comments to [reduce risks](https://urlbox.com/urlscan-alternatives.md). But sometimes, that's not enough. You should keep an archive of most if not all of your website's pages. For example, archiving pages like your Terms and Conditions and Refund and Return policies (for e-commerce businesses) may come in handy when dealing with disputes. In this article, I will cover the most important features of a social media archive tool and share 5 of the best ones available today. ## What is a Social Media Archive Tool? A social media archiving tool helps you keep your organization's records safe and accessible so you can protect yourself against lawsuits, comply with public records laws, and respond quickly to any requests for information. ## What to look for when picking a Social Media Archive Tool Each social media archive tool has its own features and limitations, so picking the one that's right for you might seem daunting. That's why we have compiled a list of the most important aspects you should keep an eye on before committing to a specific tool. ![image5](/content/social-media-archive-tools/image5.png) ### 1. Uptime - Make sure no post or comment slips by Perhaps the most important thing to look out for is the uptime of the tool you will use. This means your archiving software should be online at least 99% of the time. Some tools do not specify their uptime, which can be a red flag. If that's the case, you should ask the support agents for this information. Here's an example of an [uptime monitoring page from Urlbox](https://status.urlbox.com/?start%3D20210101%26end%3D20211231). ### 2. Archive Availability - You should be able to access your archives instantly The tool you pick should make accessing your archive as easy as possible. Some archiving software can store the records for you, but keeping all your eggs in one basket is never a good idea. You might have a hard time accessing your archive if something happens with your tool. That's why storing your records with a 3rd party cloud storage provider is important (like an S3 Amazon bucket). You can even go that extra mile and keep records on a physical hard drive. ### 3. Reliability - The social media archive tool should do its job properly, all the time Needless to say that the social media archive software you pick should do its job properly every time. Sometimes, certain tools might stop working. This is most commonly caused by updates to the social media website itself, so make sure your tool is on top of everything and is constantly updated by the company behind it. ### 4. Export Options - You should be able to export screenshots as PDF files Some entities might require proof in the form of a [PDF document](https://urlbox.com/automated-screenshots/convert-webpage-to-pdf.md) rather than a PNG or JPEG image. So to make your life easier and speed up the compliance process, the software you pick should let you download your records in multiple formats. Now that I've covered the most important aspects to look for when picking a social media archiving tool, it's time to move on to the actual archiving solutions. ## Urlbox - The Complete Web and Social Media Archive Solution Simply keeping social media records might not be enough to mitigate the risks associated with public records compliance. Urlbox is a complete archiving solution that helps you keep records of your website pages, social media posts, and comments. It's a [screenshot service API](https://urlbox.com/screenshot-api.md) you can configure to run at specific time intervals. ### Urlbox Features What makes Urlbox stand out from the crowd is the number of [features](https://urlbox.com/features.md) it has. ![image4](/content/social-media-archive-tools/image4.png) You can configure how the final screenshot will look by changing how the page renders. This is great when you want to hide cookie banners or maybe when you want to screenshot the page only after a specific element is loaded. Besides, you can also automatically export the archive records (screenshots) in various formats, such as PDF, PNG, JPEG, SVG, and many more. With Urlbox, you can also: - use a proxy server - add your own cookies - configure your own headers - customize the JS and CSS code - automatically highlight certain words - upload your records to an Amazon S3 bucket - instantly get a sharable link or download link for your record. The best part is that Urlbox works regardless of your stack, so you can immediately integrate it into your workflow. Moreover, if you are looking for a no-code web and social media archiving solution, you can connect [Urlbox with Zapier](https://urlbox.com/automated-screenshots/automate-website-screenshots-schedule.md). This makes it a breeze to save and store your records on most cloud storage providers (like Google Drive, Dropbox etc.). ### Urlbox Pricing With so many different options, you might think Urlbox is quite expensive, but it isn't. You can start with a [7-days free trial](https://urlbox.com/pricing.md) (no credit card required). The cheapest plan is $19/month and lets you capture up to 2,000 screenshots each month, roughly 30 screenshots per day. This is great for small businesses looking to create their first archive. The highest plan is $3,500/month and lets you capture up to 1,000,000 screenshots. This plan is best for enterprises. Unlike most of the other tools in this list, Urlbox doesn't charge you based on the number of active social media accounts but rather on the number of records you want to capture each month. ## Pagefreezer - Best For Social Media Monitoring Pagefreezer is a comprehensive archive solution that helps you keep records of your website's pages, social media activity, and enterprise collaboration tools communications. ![image1](/content/social-media-archive-tools/image1.png) This tool can generate and store screenshots and videos from all online channels. You can then use these to generate defensible copies that will come in handy during legal matters. They mainly target government agencies and financial services firms, but Pagefreeze might work regardless of your industry. Pagefreezer Features Perhaps the best feature of Pagefreezer is the ability to set up keyword monitoring and policy alerts on your social media accounts. You can configure this tool to look for flagged keywords, phrases, numbers, and text patterns and send you an alert when one of them appears in your posts, comments, or direct conversations. Moreover, you can quickly find the post or comment you’re looking for with their advanced search. Pagefreezer Pricing Pagefreezer pricing varies based on the client, so you must contact them for a custom quote. However, their monthly pricing plans have been reported to start at $99. Pagefreezer is great for organizations looking for an all-in-one archiving solution, but what's missing is the ability to automatically save your records in multiple different places at the same time. Moreover, they do not provide an API, so if you want to integrate an archive solution with your app, you would be better off going for Urlbox. ## Archive Social - Best For Compliance and Transparency As the name suggests, Archive Social is another social media archive software that helps you generate and store archive records. ![image2](/content/social-media-archive-tools/image2.png) It's easy and straightforward to set up. All you have to do is to connect your social media accounts, and the tool will start working. On the other hand, their search functionality usually takes a long time to load, so you'll need a bit of patience when looking for something specific. Archive Social Pricing Archive Social's prices start at $299/month, a bit pricier than the other tools on this list. Going for this plan will let you generate up to 1,600 new monthly records and connect up to 12 social accounts. The most expensive plan is $699/month, which lets you generate up to 6,000 new monthly records and connect an unlimited number of social accounts. Archive Social doesn't provide an option to save records on any 3rd party cloud storage service, nor does it have an API. ## Smarsh - Best For Messaging and Voice Archiving Smarsh claims to be the only Microsoft Teams certified solution for capturing and archiving records from 100 different sources. ![image6](/content/social-media-archive-tools/image6.png) This tool seamlessly connects with the vast majority of online channels: - most popular email clients - most popular US mobile carriers - all social media platforms - most popular voice channels - all IM and collaboration channels - any type of website. I find it important to mention that some users have reported [issues with Smarsh](https://www.capterra.com/p/130954/Email-Archiving/#reviews), from extra charges appearing on their invoices to glitchy functionality. So if you decide to use this tool, you should pay close attention to reviews and ensure that all these problems have been addressed. ## Intradyn - Best For Email Archiving Last but not least in the list of social media archiving tools is Intradyn, an all-in-one solution that helps you keep records of your emails, social media accounts, text messages, and website. ![image3](/content/social-media-archive-tools/image3.png) Intradyn works with all major social media platforms like Facebook, [Twitter](https://urlbox.com/automated-screenshots/twitter.md), and Linkedin. With the records once generated, you can then quickly search through them from a single interface. This tool has one of the most powerful built-in search engines, allowing you to use fuzzy, Boolean, proximity, and wild card search. Intradyn Pricing Intradyn doesn't display its pricing plans, so you'll have to ask for a custom quote. ## Conclusion - Best Social Media Archive Tool Each of the tools I have covered has its pros and cons. And as with everything else, the best tool for you depends on what you are trying to achieve. If you want an all-in-one solution that will also be a storage place for your archive, then you can go with Archive Social or Intradyn. But these tools make it hard, if not impossible, to back up your records on 3rd party services (or your local machine). So if you want full control over your archive, the ability to screenshot anything, and a fair price, then you should go with Urlbox. Yes, you might need the help of a developer or a Zapier expert at first, but once your system is in place, you can make sure your archive will be readily available in case of any unforeseen circumstance. ## FAQ - Social Media Archiving ### What is a social media archiving software?

In this article, we'll do a deep dive into the top automated screenshot tools in the market. ## Stillio - An automatic screenshots tool for small businesses ![](/content/stillio-alternatives/image4.png) ### Core Features If you're someone who needs to take a lot of screenshots or to capture images from websites regularly, then the Stillio automatic screenshots could be an excellent solution for you. It's simple to set up and use, plus it can make managing your screenshots a breeze. With Stillio, it's easy to capture, archive, and share screenshots automatically. It lets you capture your screen at specific time intervals, automatically. Morevoer, you can also add multiple URLs at once and filter by domain, so it's easy to pull up the images from all your favorite sites. Stillio even lets you sync the screenshots to other cloud services for quick sharing. ### Use Cases The Stillio automatic screenshots can be used for multiple use cases: 1\. Brand Management. By taking screenshots of your website or social media every week or every day, you'll have a record of what it looked like at any given time. You can use this archive as proof of content quality (or lack thereof). 2\. Website Compliance. Stillio gives you an upper hand backing you with solid evidence in the form of screenshots. 3\. SEO Tracking. Manual SERP tracking is time-consuming and tedious. Stillio can help you automate this process giving you more time to focus on your business. ### Strengths These are some of Stillio's strengths when it comes to automatic screenshots: \- Ease of use/accessibility: it's very easy to set up Stillio and access your screenshots. You can also share them easily with others through cloud services. \- Schedule for capturing images: you can specify how often you want Stillio to take screenshots. \- URL filtering feature: great when you screen capture multiple web pages simultaneously. More than that, your screenshots can be saved in an album in Dropbox or Google Drive, so you can download them later. Another great thing about Stillio is that it allows you to customize the width and height of your image before taking the screenshot, which means you can make sure your page fits on mobile devices if needed. It also lets you hide web page elements before capturing screenshots, such as ads or cookie popups. ### Weaknesses Based on online reviews, Stillio's users are generally very pleased with the service. However, there are a few common complaints that pop up quite often: \- The pricing for their plans is pretty steep. Their smallest plan starts at $29 per month, which only allows you to capture 5 different pages \- Their plans don't allow for multiple screenshots at once, but only a small number of screenshots frequently. However, this can be easily solved if you contact their support team and explain your use case. \- They don't offer an annual plan. \- You cannot choose the file type for the images. ## 3 Stillio Alternative tools to pick from ### [Urlbox](https://urlbox.com/.md) - An automated screenshot API for growth-stage businesses ![](/content/stillio-alternatives/image2.png) #### Core features Urlbox is a screenshot API that takes the hassle of capturing and rendering screenshots for your company. A screenshot API like Urlbox can save businesses hours of development time, reduce the need for engineers to maintain a separate image server, and eliminate server upkeep costs. Here are just some of the features of Urlbox: 1\. Convert URLs to PNG, JPEG, PDF, and more; 2\. Ability to accurately render emojis; 3\. Ability to render fonts exactly how they are displayed on the page; 4\. Set the width and height of your screenshot; 5\. Block certain ads and URLs, and hide cookie banners or other intrusive elements; 6\. Take retina-ready screenshots. #### Use cases Urlbox is a lightweight, easy-to-use versatile tool that lets you capture any webpage via a built-in dashboard or by using an API. For example, you can save an URL and convert it to an image you want your users to share on social media. See how you can generate [Twitter screenshots](https://urlbox.com/automated-screenshots/twitter.md). With Urlbox you can:: - Preview different headlines on client websites before release - Archive your social media influencer’s content for future reference - Generate PDFs of news articles, so they're readable offline - Take hourly screenshots of news websites to monitor changes over time \- Generate PDF invoices from a URL or HTML. People use Urlbox to create inspiration galleries, collect news articles for offline reading, generate ready to share PDF invoices from order confirmation pages, and even validate how their website looks on different screen sizes. #### Strengths The main benefit of Urlbox is that it's super easy to use. You simply add the website or app URL, and Urlbox does the rest. When using Urlbox, you'll notice that your website screenshots will be hosted on their servers instead of yours. This solves several edge cases, makes taking screenshots easier for users, and provides them with better support if something goes wrong with their website or app. With Urlbox, the images can be linked using plain old `<img>` tags if you need to embed them on your website. #### Weaknesses While this service is straightforward to use and has a very intuitive interface, there are some things you should know before you start using it. For instance, the [$19/month plan](https://urlbox.com/pricing.md) allows for 2k requests per month, which is more than enough for most users. At the same time, while Urlbox is extremely powerful, you must know how to code or hire a developer in order to use the tool at its full potential. ### [Gyazo](https://gyazo.com/en) - A screenshot tool for marketing and finance industries ![](/content/stillio-alternatives/image3.png) #### Core features Gyazo is a simple yet powerful tool that takes screenshots, gifs, and videos of whatever is on your screen. It's similar to any program you might use to take a screenshot, with the added convenience of uploading it to the platform of your choice simultaneously. This way, you can save your work and share it in one go, so you don't need to visit another website or tool. Gyazo has many features that make it perfect for sharing your screen, especially when showing off a game or other visually appealing content. #### Use cases Gyazo is perfect for eSports, marketing, and finance companies. For example, it lets you capture key moments during your streaming that won't interrupt your gaming experience, webinar, or video presentation. #### Strengths Some of Gyazo's core strengths are: - the ability to capture videos and gifs - creating a link of your capture that's ready to paste and share instantly \- instantly share your capture directly from the Gyazo app without having to leave the platform. #### Weaknesses Although Gyazo is a powerful tool for specific industries, it differs a bit from your usual screenshot tools as it’s basically an app you have to install on your machine before you can use it. At the same time, it lacks most of the features screenshot APIs have, such as: - the ability to generate automated screenshots in one go - delayed capture - storage management - web fonts support - custom geo location \- hide scrollbar. ### [Screenshotlayer](https://screenshotlayer.com/) - A screenshot API for any application ![](/content/stillio-alternatives/image1.png) #### Core features While there are many ways to generate website screenshots, the Screenshotlayer API provides a simple, streamlined image delivery experience that allows for on-the-fly image creation and quick integration with your website. The main benefit of using Screenshotlayer is that it allows you to create images of any size and complexity without worrying about memory usage, bandwidth, or page load times. It also helps ensure you won't run into issues at scale, as the system can handle thousands of requests per second with no degradation in performance. #### Use cases Freelancers and small businesses alike can use Screenshotlayer. The tool is intuitive, flexible, and well-thought-out—it's easy for new users to learn and for seasoned web developers to take advantage of more advanced features. Users can integrate it into their projects, working seamlessly with their frameworks, languages, and systems. #### Strengths Screenshotlayer's main strengths are: \- Selective Screen Capture: Screenshotlayer allows users to take screenshots of only certain portions of the page they are viewing. With this feature, one can be assured that only the necessary information will be captured in their screenshot. \- Delayed Capture: Sometimes, there are things on your screen that you don't want to include in a screenshot. Maybe it's an error message or a pop-up that you don't feel comfortable sharing. Screenshotlayer lets you pick a time delay before the screenshot is taken. \- Real-Time Image Resize: It's all too common for screenshots to come out larger than they need to be. You can scroll around in them and zoom in and out, but it would be nice if they could just be resized automatically to fit their intended use. Screenshotlayer has this feature built-in. #### Weaknesses When it comes to weaknesses, users usually complain about: - no annotation and markup tools - no automated screenshots - no lazy loading \- no responsive screen capture. ## Selecting a Stillio Alternative Stillio is an excellent tool for businesses that need to take a lot of automated screenshots. However, it has limited capabilities in terms of customization. As a result, many companies typically use other screenshot tools, such as Urlbox, Gyazo, or Screenshotlayer. Urlbox is designed to make taking screenshots easier and more efficient by providing a simple API that works directly with your browser. You can begin taking screenshots instantly with just one line of code and a few minutes of setup time. We've also built Urlbox to be highly customizable, so you can take screenshots exactly how you want them. With Urlbox's customizability and ability to capture responsive images, we think it's the perfect Stillio alternative for your business needs.

Source: https://urlbox.com/track-product-prices Last updated: 2022-11-29 --- As a business owner, staying on top of your industry's latest trends and prices is important to ensure your products are always competitively priced. But tracking the prices of products on Amazon and eBay can be a daunting task. In this article, we'll discuss the best ways to track product prices on Amazon, eBay, or any other online store, so you can make sure you're offering the best deals to your customers. ## How and why to keep track of the price history of a product Knowing the price trajectory of your products will help you adjust prices accordingly and ensure you are not missing out on any potential profits. There are multiple tools that can help you keep tabs on how different product prices have changed over time. You can use the information they provide to uncover patterns or trends. This will help you determine whether or not you need to adjust the price of your product to remain competitive. Moreover, these tools can help you review your pricing strategy regularly to ensure it's still working for your business model. ## Types of price tracking tools Price tracking tools can range from basic manual investigation of competitor pricing to sophisticated software programs or platforms. Tools like dynamic pricing engines or crawlers track changing product prices on specific platforms, while comparison shopping engines show where a product is most competitively priced. But these tools are built exclusively for certain websites (like Amazon, Walmart or eBay). And this means two things: 1. If you want to track prices on multiple platforms simultaneously, you might need more than one tool. 2. If you want to track smaller or niche websites (not global retailers), you will need a custom price tracking solution. But things can get even more complicated for specific industries where you need to consider seasonal demand and other variables (like the hospitality industry). That's why we've broken down this list of price tracking tools based on individual use cases. ## Urlbox - Best tool to archive and track product price history Urlbox is a powerful, easy-to-use tool for taking screenshots of product price pages. It works with any URL, making it the best choice for people tracking prices on multiple websites simultaneously. All you have to do is enter the desired product page URL into the Urlbox interface, select any additional options (full page screenshot, auto accept cookies etc.), and click “Generate”. Then you can save the screenshot as a PNG, JPG, or PDF file. But the best part is that you don't have to manually do this each and every day, as Urlbox provides a comprehensive [Zapier connector](https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier.md). You can use Urlbox to create and [keep archives of any webpage](https://urlbox.com/website-archive-tools.md), which makes it a breeze to create your own product price history database. ### How Urlbox Works First, you must [create an account](https://urlbox.com/pricing.md) (you can try Urlbox free for 7 days). Then you'll be automatically redirected to your dashboard. Simply click on the "Sandbox" button on the right part of the screen and paste in the URL of the page you want to capture. ![image4](/content/track-product-prices/image4.png) For example, say I want to track and archive the "Adidas Yeezy 500" product price on eBay. All I have to do is paste in the URL of the search page, select "Full page" and click "Generate". The URL I used for this example is: ``` https://www.ebay.com/sch/i.html?_from=R40&_nkw=adidas+Yeezy+500&_sacat=11450&LH_BIN=1&rt=nc&LH_ItemCondition=1000 ``` This is [the final result](https://urlbox.com/content/track-product-prices/image5.png.md). You can do this daily by manually adding the URL and saving the images, but that can get repetitive pretty fast. Instead, you can use the Zapier connector in combination with a Google Sheet. Here's a step-by-step guide covering how to automatically [archive pages with Urlbox and Zapier](https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier.md). Once you generate the screenshots, you can save them on any cloud storage platform (Google Drive, Dropbox etc.) Last but not least, you can leverage Urlbox's API to create your own app. It works with any programming language, so you can also integrate it into an existing app. Check the [documentation](https://urlbox.com/docs.md) here for more information. ### Urlbox Pricing You can try Urlbox for free for 7 days, after which you can upgrade to a paid plan. The cheapest plan is $10 per month and lets you archive up to 1,000 pages per month. Each additional request costs $0.01. ## Visualping - Best price monitor tool Visualping provides comprehensive and easy-to-use price monitoring. ![image2](/content/track-product-prices/image2.png) It takes just a few simple steps to start monitoring any web page: enter the URL, select a frequency for checking, and activate the monitor. Then Visualping will automatically monitor the page for any changes and send you email notifications when anything changes. With Visualping, you can set up multiple pages to monitor at once and customize settings for each alert. Plus, its simple design makes it incredibly easy to use with no technical knowledge required. Like Urlbox, Visualping works with any website, making it great if you want to get updates from multiple platforms. However, there are some drawbacks that you have to consider: - It is possible to track changes on search and category pages, but keeping track of everything can be a hurdle. - There is a specific number of pages you can track each month. For example, the smallest plan allows you to check just 25 pages per month. Overall, Visualping is great if you sell a few products and want to check a small number of product pages. But costs can go up rather quickly as you start tracking more pages. ## CamelCamelCamel - Best Amazon price tracker tool CamelCamelCamel provides detailed historical price data, allowing you to track and analyze pricing trends over time. ![image3](/content/track-product-prices/image3.png) The service monitors global prices across different Amazon marketplaces and shows individual item pricing trends in user-friendly graphs. It also offers convenient price alerts and notifications when prices drop, so you can act quickly to update your pricing strategy and stay competitive. All you have to do is search for a specific product, add your email address and select when you want to receive a notification based on the price of that product. In addition, by going to their website, you can browse the "Popular Products" section. This can prove useful if you want to discover products you want to resell after a certain period. CamelCamelCamel also has a Chrome extension that can be quite useful if you are in the product discovery phase. Since this tool can only track Amazon prices, it might not be the best for people who want to keep tabs on multiple competitors across different platforms. However, CamelCamelCamel is the only completely free Amazon price tracker tool. ## Keepa - Best Amazon price history tracker tool Much like the previous tool, Keepa provides valuable insights into competitive pricing dynamics, including competitor pricing information and price trends across multiple platforms. ![image1](/content/track-product-prices/image1.png) What makes Keepa one of the best price history tracker tools is that it tracks over 3 billion products from Amazon and 3rd party sellers. You can access this history by installing a browser extension or directly from their website. Keepa also offers email alerts to notify you when a product's price changes or when a specific price is reached. Last but not least, you can integrate Keepa with your existing app by using their API. Pricing starts at €49 per month, for which you get 20 tokens per minute. Each token allows you to retrieve the complete data set for one product. Keepa is great if you want to keep track of price changes for vast amounts of Amazon products, but it might not be great for people looking to archive prices on niche websites or smaller retailers. ## What is the best price tracker tool? If you are looking for a complete solution that lets you archive and track any product page just by its URL, you should pick either Urlbox or Visualping. On the other hand, if you want to track and access the price history for Amazon products, then you should pick either CamelCamelCamel or Keepa. ## FAQ ### What is a product price tracker tool? A product price tracker is a tool that can help you keep track of the prices of products during a specific amount of time across different platforms. Consumers use these types of tools to get deals on items they want to buy. On the other hand, businesses leverage the information provided by these tools to make sure their pricing strategies stay competitive. ### How to check price history? You can see the price history of an Amazon product by using a price tracker. You can try using [Wayback Machine or an alternative](https://urlbox.com/wayback-machine-alternatives.md) for other platforms or websites. ### How to track product prices? The best way to track product prices is to use a product price tracker tool. You can use one created specifically for the platform you want to track or create your own system using Urlbox or Visualping. --- # Urlscan.io Alternatives for Mitigating the Risks of Cyber Attacks > Discover 4 Urlscan.io alternatives and the best ways to prepare your business in case you ever get hacked. Source: https://urlbox.com/urlscan-alternatives Last updated: 2022-05-27 --- Urlscan.io is a free online website scanner. It's used for detecting malicious links, suspicious files, and directories in case your website was attacked by a hacker. The service detects the technologies used by the website you scan and provides basic page statistics, like the number of requests, the number of 3rd party cookies, and the domains/subdomains they are generated by.![](/content/urlscan-alternatives/image1.png) The service is great for uncovering security issues, but it doesn't help you prevent or fix them. In this article, I am going to share 4 Urlscan.io alternatives and the best ways to prepare your business in case you ever get hacked. ## Types of hacks Urlscan can discover Distributed Denial Of Service or DDoS attacks are among the most common types of hacks targeting small and medium businesses (SMBs). Although it may not seem that a DDoS attack is a big issue, business owners should know that it can be more destructive than expected. Just imagine what could happen if your site went down for more than 24 hours or if it has been severely affected by an ongoing hack. Now the good thing about DDoS attacks is that most of them are simply turning your website offline. If you are lucky enough, you can catch the attack while it's happening and take the necessary measures to mitigate its effects. But in some cases, hacks can be way more intrusive and destructive. Some attacks change the way your website looks and its contents without your knowledge or consent. A hacker can do this by exploiting security vulnerabilities in your website's code, which lets them access your database. These attacks conclude with a ransom you have to pay, but some people that do it never get access to their website and files again. And that's why you have to be prepared for the worse. ## Urlbox - Best Urlscan.io alternative to generate a static copy of your website Urlbox is a website screenshot service that helps you generate a copy of your website by automatically capturing and storing all your webpages as HTML files. ![](/content/urlscan-alternatives/image3.png) You can configure Urlbox to screenshot your website at certain time intervals automatically. Then you can send the files to Amazon S3 for that extra layer of security. These screenshots can be exported in different file formats, such as PNG, JPEG, or PDF, but the great thing about Urlbox is that it also lets you save them as HTML files. ![](/content/urlscan-alternatives/image2.png) Keeping a copy of all your pages could be a lifesaver when the worst happens. In case someone gets access to your database and deletes or alters its content, you will find yourself unable to restore your previous backups. Sure, you can always contract a security specialist to help you regain control of your files, but this is a time-consuming and costly process. On the other hand, if your backups reside on an Amazon server, you can simply send them over to your developers so they can quickly implement them and get your website back up. ### How Urlbox works Urlbox is basically an API. This makes it easy to integrate into your existing application or workflow. It has extensive documentation and official client libraries for Ruby, PHP, Python, [Node.JS](https://www.npmjs.com/package/urlbox), and many more, which makes it extremely straightforward to implement. It comes with a plethora of different options that allow you to configure your final screenshots, like the ability to remove cookie banners, block ads, and even automatically log in before you render a page. Urlbox also allows you to specify a User Agent before you take the screenshot, so if your website has different versions for different devices or browsers, you can be sure your files will feature an exact replica of your web pages. ### Urlbox helps SMBs mitigate the risks of a hack Urlbox works best for businesses and individuals looking for a scalable solution that can automatically generate HTML screenshots and store them in a secure server as a backup. It doesn't matter if your website has tens or thousands of pages. You can use the Urlbox API to screenshot them as often as a few times per day automatically. The Urlbox pricing plan starts at $19/month, which lets you make 2,000 requests per month. The bigger the plan, the cheaper each request gets. One of the most popular options among businesses is the Advanced plan which starts at $249/month and allows you to make up to 60,000 monthly requests. Now, of course, it all depends on how big your website actually is and how many times you want to back it up per day, so when you pick a plan, make sure to take that into consideration. For example, say your website has 200 pages, and you want to back them up daily. This would translate into roughly 6,000 requests per month, in which case you will go with the Standard plan. You can view the complete list of prices on the [free trial](https://urlbox.com/pricing.md). ## Gtmetrix.com - Best Urlscan.io alternative to analyze a website's load Gtmetrix lets you check how and what a website loads. Once you type in a URL and select a server, the service will start analyzing all the details of the website you are analyzing. It shows you a breakdown of the loading speed, the total number of requests, and what generated them. Moreover, you can see a breakdown of all these requests by navigating to the Waterfall subsection of Gtmetrix. Adding 3rd party cookies to your website can have dire consequences if the service behind them gets hacked. Ill-intended individuals can access sensitive user information from these cookies. For example, if you use a 3rd party email marketing software, chances are it asked you to add a tracking code to your website. If the service is new and lacks certain security features, hackers can tap into it and copy the email addresses and names of your leads. Even though this scenario doesn't happen often, it is definitely a security vulnerability, so you want to keep an eye out for malicious 3rd party URLs that might be loading snippets of code on your website. On the other hand, hackers can tap into your server and use its resources for computational power. This would make your website really slow, greatly affecting user experience. That's another reason why you would want to run the Gtmetrix analysis for your website. ## Urlvoid.com - Best Urlscan.io alternative to check a website's reputation You'll find Urlvoid as being on the simpler side of Urlscan alternatives. This free service lets you check a website's reputation and discover if it's infected by analyzing 30+ blocklist engines and online website reputation services. Cyber security companies and IT researchers use it to speed up the process of cyber threat analysis by identifying potentially malicious websites that have been classified as a threat by multiple trusted sources. Urlvoid was created by the team behind Apivoid as a visual interface to their domain reputation API. So if you want to batch-test websites for potentially malicious pieces of code, be sure to give them a try. ## Virustotal.com - Best Urlscan.io alternative to check files and IPs for malicious code Last but not least on the list is Virustotal. Compared to the other alternatives, this service also lets you check files and IPs for malicious code. All you have to do is to upload a file or type in a URL, and you'll instantly get a threat analysis report. Virustotal uses a comprehensive list of online website reputation services to assess the risks of a potential infestation. Moreover, if you analyze a URL, it checks if there are any redirects made from it and shows you its status code, body length, and even the headers. You can also see a breakdown of the redirection chain and a list of all the trackers present on the analyzed URL/IP. This service also provides an API if you want to automate the analysis and scale it across a vast number of different websites. ## Get yourself prepared before it’s too late The number of hacked websites has steadily increased year over year, but the problem exploded during the pandemic when [cybercrime increased by a staggering 600%](https://purplesec.us/resources/cyber-security-statistics). It might be a matter of time before you fall victim to one of these attacks, so make sure you're prepared by backing up your website and keeping a static HTML copy of all your web pages somewhere safe. Spend a few minutes today and earn hours, if not days of headaches, by backing up your pages as HTML static files with Urlbox.

Our guide outlines to top 5 options, detailing features and benefits. Let’s dive in! Source: https://urlbox.com/visualping-alternatives Last updated: 2023-10-04 --- Visualping is one of the most renowned website monitoring tools on the market. Its simplicity makes it a great choice for individuals, but its lack of advanced functionalities prompts some businesses look for an alternative. In this article, we’ll cover the top 5 advanced Visualping alternatives to monitor websites for changes at scale, analyzing their reviews, key features, and differentiators. Some of these tools can track changes behind a login screen and allow you to archive web pages. At the same time, they come with a built-in Zapier connector and a developer-friendly API, making them a great choice for all businesses, regardless of size. ## Urlbox - Best for monitoring pages behind a login screen ![image5](content/visualping-alternatives/image5.png) G2 rating: [4.8 out of 5 stars](https://www.g2.com/products/urlbox-io/reviews) Urlbox is a screenshot service API used by businesses of all sizes to capture snapshots of webpages at specific time intervals. You can use it to [monitor your online reputation](https://urlbox.com/online-reputation-monitoring.md), [track brand mentions](https://urlbox.com/brand-monitoring.md) across the web, [track product prices](https://urlbox.com/track-product-prices.md) on different platforms, and even [archive social media posts](https://urlbox.com/social-media-archive-tools.md). Compared to Visualping, you might find the setup process a bit more complex. This is due to Urlbox’s advanced functionalities and configuration options: - Monitor pages behind a login screen: Urlbox allows you to set up custom cookies before loading the target URL, which makes it possible for it to screenshot pages behind a login screen. - Archive webpages at specific time intervals: Go beyond monitoring by creating an archive of the websites you’re interested in. Urlbox integrates with Amazon S3 by default, allowing you to upload your screenshots to S3 buckets automatically. - Zapier connector: Connect Urlbox with thousands of different apps via Zapier. - Developer-friendly: Urlbox works with all major programming languages, making it a great choice for developers regardless of their tech stack. - Various output formats: You can export your screenshots as images in various formats, including PNG, JPEG, WEBP or AVIF, as a PDF document and even as an HTML file. These features make Urlbox a great Visualping alternative, especially if you are a developer looking to monitor websites for changes at scale. It’s important to mention that Urlbox can not analyze the screenshot by itself. This means you’ll have to manually analyze each image for changes or use a separate tool (like ChatGPT) to point out the differences between 2 screenshots. [Pricing plans](https://urlbox.com/pricing.md): Urlbox starts at just $19/month with various options depending on the volume of screenshots and features you need. Sign up now and enjoy a [7-day free trial](https://urlbox.com/pricing.md) so you can try Urlbox before committing to a paid plan. ## Browse AI ![image2](content/visualping-alternatives/image2.png) G2 rating: [4.8 out of 5 stars](https://www.g2.com/products/browse-ai/reviews) Browse AI is a web automation platform that allows you to monitor websites for changes. It works differently compared to Visualping, as it extracts data from websites and uploads it into rows of a Spreadsheet. Because Browse AI is actually a web scraper, its setup process can be quite complex and repetitive. First, you need to specify the URL you want to monitor. Then, you’ll be asked to install their Chrome extension that will record your actions on the target webpage. Once you complete this configuration, Browse AI will scrape the webpage and extract the data into a Spreadsheet. You can configure how often you want this to happen and even get notified when it detects changes. This functionality makes it great for businesses looking to monitor and extract data at the same time, especially if this data is dynamically generated. You can try Browse AI by signing up for their free plan, which allows you to extract 500 rows of data per month. Paid plans start at $19 per month when billed yearly and allow you to extract 50,000 rows of data per year. Key features: - Human-like navigation: Browse AI's visual automation technology allows it to browse websites just as a human would, allowing you to select specific elements you want to track just by clicking on them. - Complex task handling: The platform can fill out forms, manage cookies, and even tackle CAPTCHAs. - Prebuilt automations: Browse AI comes with prebuilt robots you can implement in a few clicks that allow you to extract data from prominent websites, such as Product Hunt, Indeed, Yelp, and more. You can track this data and get notified when certain keywords pop up. ## Sken ![image4](content/visualping-alternatives/image4.png) G2 rating: [4.6 out of 5 stars](https://www.g2.com/products/sken-io/reviews) Sken is a website monitoring tool with the sole purpose of tracking changes on web pages. Its setup process is similar to Visualping, as you simply input the URL of the site you wish to monitor and select the section or element you want to track. It also allows you to hide specific elements, like cookie banners or popups, making it easy to monitor just what’s truly important to you. However, it's worth noting that the tool is relatively basic and doesn't offer extensive configuration options. It doesn’t even have the option to monitor the mobile version of a website. If that’s something you are not looking for, then Sken might be a great Visualping alternative, especially since it’s three times cheaper. Its Standard plan goes for $12 per month and allows you to run up to 3,000 checks per month. Key features: - Fully customizable scheduler: Sken’s intuitive timetable allows you to easily select the day and hour when you want it to check the target URL. - Visual configuration: Simply add your URL and select the elements or sections you want to monitor. - Chart preview: If you are tracking numerical values, like product prices, then you can visualize the changes in a chart. ## Change Tower ![image1](content/visualping-alternatives/image1.png) G2 rating: [4 out of 5 stars](https://www.g2.com/products/changetower/reviews) ChangeTower is a simple-to-use website change detection and archiving platform. It works in the same way as Visualping but comes with more advanced tracking features, such as the ability to monitor text files and PDFs.

Source: https://urlbox.com/wayback-machine-alternatives Last updated: 2025-03-21 --- Wayback Machine is the oldest and most comprehensive internet archive website. Established in 1996 by a non-profit organization, it has collected a staggering 625 billion web pages since this article was published. To see how websites have evolved over the years, you should search them on Wayback Machine. The bigger the website, the more chances you have to find multiple screenshots. Wayback Machine is, by definition, the archived web. It's of great use when looking for well-known websites or broad website categories, but it's not so good if you want to keep tabs on niche websites. In this article, I will share 6 of the best Wayback Machine alternatives you can use to archive sites and web pages with automated screenshots. ![image6](/content/wayback-machine-alternatives/image6.jpg) ## Most common Wayback Machine use cases Businesses from virtually all markets use Wayback Machine to access historical records of web pages. Among other things, Wayback Machine can help you: - Keep track of competitors - You can check how they positioned their product over time, how their pricing structure has changed, and how many reviews they had at certain time intervals. All this information is vital if you want to do a competitive analysis of your target market. - Back up the content on your website - Blog articles should constantly get updated, but some information can be lost. You can use Wayback Machine to store and access your website's original content anytime. - Keep track of changes to any website - Web archiving means more than simply storing a website's content, as you'll most likely need to access the creatives as well. At the same time, you'll also have to keep an eye on the structure of a page, which is created by a combination of CSS, HTML, and Javascript. - Mitigate link rot and broken links - When citing a web page on your website, you must ensure the link will be valid for as long as possible. You can use a Wayback Machine-generated URL to mitigate the risk of link rot, otherwise known as broken links. Wayback Machine might not be the best choice depending on why you need to keep a web archive. Perhaps the most important thing is that you cannot control the archive uptime. If the web.archive.org website goes down, you'll need to wait for it to come back online if you want to access an archived web page. In addition, whenever you want to save a website snapshot, you will have to manually type in the URL, as there are no guarantees Wayback Machine will capture daily or even weekly screenshots of said website. With that being said, let's look over some Wayback Machine alternatives you can start using today for web archiving and much more. ## Urlbox - The best screenshot API to archive, save, and keep track of website changes One of the best ways to archive a web page is to take a screenshot. This guarantees that the page structure will be preserved exactly as is. Besides, you can save the screenshot and safely store it anywhere you want. Urlbox is an [screenshot API](https://urlbox.com/screenshot-api.md) built to automate the process of capturing screenshots. It lets you download the screen capture in many different file types, like PNG, JPEG, PDF, or even static HTML. At the same time, you can use it to upload your screenshots to an S3 bucket. It works with all major programming languages and features comprehensive [documentation](https://urlbox.com/docs.md). ![image2](/content/wayback-machine-alternatives/image2.png) ### Urlbox Use Cases You can configure Urlbox to capture screenshots as often as you'd like, but no more than 60 times per minute. Even so, no website changes that often in such a small amount of time, so you can safely start using Urlbox to archive and save any web page, especially if you need to: - keep an eye on competitors' websites - keep track of changes on your website - archive posts on social media (example on how to save [Twitter screenshot](https://urlbox.com/automated-screenshots/twitter.md)) - access all your screenshot history. ### Urlbox Features An archive is only as good as its records, so you must ensure each web page you add to it looks exactly as it should. Since websites load differently depending on browsers and devices, the archive tool you will use must be able to capture each page correctly. This is where Urlbox shines. With a complete set of features built specifically for high-quality screenshots, you won't have to worry about the integrity of your archive records. Urlbox lets you configure how the page loads, allowing you to capture the look and feel of a web page before storing it for later reference. Among other things, with Urlbox, you can: - export screenshots as PNG, JPEG, WEBP, PDF, SVG, and even HTML files - automatically block popups and ads - dismiss cookie banners - use a proxy server - set custom cookies - specify geolocation. Moreover, you can configure Urlbox to bypass captchas automatically, delay the screen capture until an element is part of the DOM or not, and so much more. View the [full list of features](https://urlbox.com/features.md). ### Urlbox Pricing Urlbox pricing plans start at $19 per month and let you capture up to 2,000 screenshots. The more web pages you want to archive, the better the price will be. For example, if you need to capture 20,000 screenshots per month the price is $90. This makes Urlbox one of the best Wayback Machine alternatives for businesses looking to archive websites at scale. Try Urlbox with the [7-day free trial](https://urlbox.com/pricing.md) (no credit card required). ## Stillio - Best alternative to automatically capture and archive website screenshots Stillio is a SaaS that lets you capture and archive screenshots at specific intervals. It's extremely easy to use, as all you have to do is add the URLs you want to archive, set up how often you want it to capture screenshots of the specified web pages, and let it run. ### Stillio Use Cases You can use it to: - keep track of your competitors' websites - verify that your sponsored content gets published - save the proof you need that your website and social media comply with any regulations. ![image4](/content/wayback-machine-alternatives/image4.jpg) ### Stillio Features Stillio was built specifically with archiving in mind, so it's only natural it comes with all the features you need to compile an excellent web archive. Among other things, this tool lets you: - Set screenshot frequency - Add multiple URLs at once - Filter the archive by domain - Organise and filter your screenshots by tags. ### Stillio Pricing Stillio is pricier than the first alternative on this list. Their cheapest plan starts at $29/month and lets you track up to 5 different web pages. If you would rather get rid of the screenshot limit, you must go with their Top Shot plan, which will set you back $299/month. This will also let you capture screenshots once every 5 minutes, sync Stillio with up to 3 3rd party apps and enjoy priority email support. ## Archive Today - Most similar to Wayback Machine The previous alternatives take web archiving to a different level. Still, if you are looking for a relatively simple and, most importantly, free way to save web pages. ### Archive Today Use Cases This is nothing but an archiving tool built specifically to mitigate the risk of link rot (or broken backlinks). You can use Archive Today to generate a snapshot of any webpage. The tool will automatically generate a link you can add in your citations, thus making sure the page you are referring to will never go offline (as long as Archive Today stays live). ![image3](/content/wayback-machine-alternatives/image3.jpg) ### Archive Today Features This tool lets you input a URL. Then it will simply take a snapshot of it and provide you with a permalink you can use in your citations. You can also search the archives for a saved snapshot from their homepage. Archive Today is free to use, similar to Wayback Machine. ## Imagematic - The best tool to keep track of changes on small websites Imagematic is a SaaS-based service that lets you capture and store images of your website's pages. ![image1](/content/wayback-machine-alternatives/image1.jpg) ### Imagematic Use Cases Compared to the other alternatives I have presented thus far, you can use Imagematic to get alerts when a page changes unexpectedly. This is great in case of an automatic tech stack update (that breaks down your front end) or in case your website gets hacked. You can also use it to archive your privacy policy and ToS pages in case of a regulatory compliance inspection or to defend against fraudulent chargebacks by storing your returns policy web page. ### Imagematic Features This tool was built for non-developers. Thus, all you have to do to make it work is to add the URL of the page you want to capture and store and specify how often you want it to be captured. Moreover, you'll have unlimited access to your archive if you have an account with them. ### Imagematic Pricing You can start using Imagematic for free to capture a single URL daily. Their cheapest plan is $4.99 per month and lets you capture up to 60 images. This is great if you want to store weekly instances of up to 10 pages. Their highest plan is $199.99 per month and lets you capture and store up to 10,000 web pages. It also allows you to set up the frequency at which the screenshots are taken to as often as 5 minutes. ## Perma CC - Best service to generate permalinks Perma CC helps scholars, journals, courts, and others create permanent records of the web sources they cite. It was built to completely mitigate the risk of broken backlinks by generating a permalink that will always remain live (as long as Perma CC remains live). ![image5](/content/wayback-machine-alternatives/image5.jpg) ### Perma CC Use Cases You should use Perma CC if you need to make sure that your linked citations will never lead to broken, blank, altered, or malicious pages. At the same time, you can use it to save any web page for later reference. ### Perma CC Features Built with simplicity in mind, all you have to do to generate a permalink is to copy and paste a URL in their web interface. It will automatically generate a new record in a matter of seconds. ### Perma CC Pricing This is the priciest of all Wayback Machine alternatives. Their cheapest plan (Basic Use) is $10 per month and lets you generate ten links. The biggest plan they have (Heavy Use) will set you back $100 per month and let you add up to 500 new links in that same amount of time. However, you can try Perma CC for free, as every account gets ten free links upon registration. ## Visualping - The best tool to automatically monitor site changes Although not exactly an internet archive tool, I felt like including Visualping as it does something that some of you might look for: monitor web page changes. It captures screenshots every few minutes, hours, daily, weekly or monthly and lets you know if something changes on the page you are tracking. ### Visualping Use Cases You can use this tool to keep track of changes to your most important pages or your competitors'. ### Visualping Features Besides setting up the frequency of screenshots, Visualping lets you: - set up what you want to be compared (text, element, or web page section) - configure how important the change should be (in percentages) - automatically set up notifications to any email address - use one of their built-in proxies. ### Visualping Pricing You can start using Visualping for free if you need to keep track of daily changes on up to 5 pages.

Source: https://urlbox.com/website-archive-tools Last updated: 2022-11-10 --- Archiving a webpage used to be a tedious process. Most often than not, you'd need a team of developers to create and maintain a dedicated screenshot service capable of capturing hundreds, if not tens of thousands, of screenshots. Then you'd need a separate service to save these images in the cloud. There are a handful of problems that come with this approach: - you have to double-check each screenshot to make sure it looks exactly like the webpage you just captured - the final image quality is usually pretty bad, especially if you capture a [full-page screenshot](https://urlbox.com/automated-screenshots/how-to-take-full-page-screenshots.md) - in-house implementations are prone to errors and bugs, which can drastically increase the cost of building a website archive. But you can solve all these problems using a website screenshot archive tool. These services can help you build your web archive with minimal cost and maintenance. In this article, I will show you how to archive websites conveniently using the best screenshot service APIs available today. ## Why Wayback Machine is not the best tool to keep a web archive Many individuals and businesses rely on Wayback Machine to see an earlier version of a website or specific webpage. But this proves to be counterproductive, as you can not be sure when Wayback Machine will capture a screenshot. As a rule of thumb, the bigger the website, the more chances you have to find daily snapshots or its web pages. But if you want to [archive smaller or niche websites](https://urlbox.com/wayback-machine-alternatives.md), you will need to use a dedicated service that gives you complete control over the frequency of snapshots. Building your own web archive comes with many benefits: - you can access the web archive at any time - you can save the final image in any format you want (JPEG, PNG, PDF, or even HTML) - you can document the website archive history, which might be considered proof - you can even [archive social media posts](https://urlbox.com/social-media-archive-tools.md) and other online mentions for future use. Let's jump to the best screenshot service API you can use to build and manage your own website archive. ## Urlbox - The best screenshot service API to archive websites Urlbox is a screenshot service API built specifically for businesses seeking to capture high-quality webpage snapshots. It works with all major programming languages but also has a Zapier integration, which lets you build your web archive using exclusively no-code tools. Here's a step-by-step guide on how to use [Urlbox with Zapier](https://urlbox.com/automated-screenshots/swipe-file-with-google-sheets-zapier.md) to capture daily screenshots of certain web pages. ### How to build a web archive with Urlbox Urlbox makes it incredibly easy to start capturing screenshots, as all you have to do is set up a simple request that will look like this: ![image1](/content/website-archive-tools/image2.png) The above query will generate a screenshot of "example.com" and return it as a PDF file, which you can later save or upload to an Amazon S3 bucket (or your preferred cloud storage service). As mentioned before, this is the most basic request you can make. Still, Urlbox comes with many different configuration options so you can generate a pixel-perfect, ready-to-archive screenshot: - configure the viewport dimensions or capture a full-page screenshot - automatically block ads, hide cookie banners (or click accept) - customize the page with extra JS or CSS code - set up a custom user agent, headers, and cookies - tunnel the request through your proxy server to ensure the page loads precisely as it would from your own IP - configure Urlbox to scroll through a whole page, automatically record the scroll, and export it as an MP4 file. You can view all these options, plus more, by [signing up for an account](https://urlbox.com/pricing.md) (free for seven days) and navigating to the Sandbox mode. In addition, you can be sure the output will look exactly like the original page. Urlbox renders web fonts and emojis correctly, works flawlessly with flexbox layouts, and even loads lazy loading images. Once satisfied with how the page will be rendered, you can export its snapshot in various formats (PNG, JPEG, WEBP, AVIF, SVG, PDF, HTML, or MP4). ### Urlbox Pricing You can try out Urlbox for free for seven days, after which you can upgrade to one of the three plans: - [The Lo-Fi Plan](https://urlbox.com/signup/lo-fi-monthly-a.md): Starting at $19 monthly for 2,000 screenshots, this plan is perfect for generating thumbnails. - [The Hi-Fi Plan](https://urlbox.com/signup/hi-fi-monthly-a.md): Priced at $49 per month for 5,000 screenshots, this plan is best for businesses looking to capture creating pixel-perfect screenshots and retina-resolution images. - [The Ultra Plan](https://urlbox.com/signup/ultra-monthly-a.md): For $99 per month for 15,000 screeenshots, this plan is ideal for advanced web imaging. All plans come with all features, which means you'll pay just for the number of archive records you want to generate each month. In addition, Urlbox has a 30-day money-back guarantee, so if you are unhappy with it for any reason, you can always get a refund. ## Stillio - Automatic website archive tool for small websites You can use [Stillio](https://urlbox.com/stillio-alternatives.md) to capture screenshots at specific time intervals, automatically export them to cloud storage providers, and even tag each snapshot so you can easily sort through them. ![image1](/content/website-archive-tools/image1.png) ### How to build a web archive with Stillio Getting started with Stillio is exceptionally straightforward. After you've signed up for an account, you will be taken to Stillio's dashboard, where you can set up what URLs you want to capture and how often. But Stillio does more than that, as you can: - set the screenshot's width and height - configure a custom user agent - set custom cookies - hide or click elements before the screenshot is taken - timestamp screenshots with a watermark featuring the time and date - add multiple pages at once by uploading the sitemap file of your target website. ### Stillio Pricing Stillio comes with a 14-day free trial, after which you can upgrade to one of their five paid plans: - Snap Shot Plan - for $29 per month, you can track up to 5 web pages, sync one app, and capture screenshots daily, weekly, or monthly - Hot Shot Plan - for $79 per month, you can track up to 25 web pages, sync one app, capture screenshots daily, weekly, or monthly - Big Shot Plan - for $199 per month, you can track up to 100 web pages, sync two apps, capture screenshots daily, weekly, or monthly - Top Shot Plan - starting at $299 per month, you can track unlimited web pages, sync three apps, and capture screenshots every 5 minutes. You can also contact them for an enterprise plan to get you custom cloud integrations and web archiving options. ## Intradyn - All-in-one organization archiving solution Intradyn is a complete archiving solution that lets you keep records of everything in your organization, from emails and SMS messages to social media posts. ![image3](/content/website-archive-tools/image3.png) ### Intradyn Features Intradyn was created to help businesses tackle regulatory compliance, eDiscovery, and litigation. It's comprised of 4 products that blend together: - Email Archiving - capture, save, and index all emails in real-time - [Social Media Archiving](https://urlbox.com/social-media-archive-tools.md) - comprehensive social media archiving across all channels - Text Message Archiving - save, categorize and index all mobile content for fast retrieval. It's unclear if you can also use Intradyn to archive web pages, although you can find out by contacting them and asking for a demo. At the same time, they do not display their pricing plans, so if you want to use this service, you'll need to get in touch with them. ## What is the best website screenshot archive tool? There are multiple factors to consider before you decide to go with a website screenshot archive tool: - How many pages do you want to archive? - How often do you want to screenshot them? - Do you want to build the system yourself (either by coding or using no-code tools)? If you are going to create a massive web archive featuring hundreds of websites (or more), then you should go with [Urlbox](https://urlbox.com/pricing.md), as it's the cheapest and most reliable solution from this list. But choosing this service will require you to build the archive system yourself or get a developer's help. On the other hand, if you want to archive a few pages at a time, you should go with Stillio. It's faster to get started with, as all you have to do is configure the URLs you want to capture and how often, but it is more expensive than Urlbox. Whatever solution you choose, make sure to back up your archive to a cloud hosting service. That way, you'll be sure your website screenshots history can not be accidentally altered, plus you can effortlessly search through all instances. --- # Comparing the 5 Best Website Monitoring Tools for Small Businesses > Discover 5 of the best website monitoring tools for small businesses to help monitor your website's health and performance.

On the other hand, if you want to monitor the changes made to specific web pages, you should pick [Urlbox](https://urlbox.com/pricing.md). --- # The Best Website Screenshot Generator Tools and APIs > We've put together this list of the best website screenshot generators to help you find the one best suited for your use case. Check out the full list here! Source: https://urlbox.com/website-screenshot-generator-tools-apis Last updated: 2025-03-21 --- A website screenshot generator is an online tool, API, or library that facilitates the process of generating an image (or more) of one or multiple web pages. In other words, it helps you capture a website's content as an image. Advanced website screenshot generators come with a plethora of customization options, such as: - generate images in different formats ([PNG](https://urlbox.com/automated-screenshots/html-to-png.md), JPEG, PDF, etc.) - automatically block pop-ups before you take the screenshot - automatically accept cookie banners - prevent ads from being displayed - bypass captchas - use a proxy server. Now there aren't a lot of screenshot generators that do everything I listed above, and you might not even need something so advanced. So I've put together this list of the best website screenshot generators to help you find the one best suited for your use case. ## Responsive website screenshot generator APIs A website screenshot API is an easy way to add screenshot generation into your app without installing any dependencies or managing any software. You don't need to write any code, set up servers, or worry about scaling, security and uptime. ![](/content/website-screenshot-generator-tools-apis/image4.png) For example, website screenshot APIs are great for web dev agencies that want to share prototypes with clients before they finish a project. That's because it's better to share images of a website rather than the product itself to get feedback. Most clients will pick on functionality-related issues before giving the agency the chance to present the prototype. Here are two of the best website screenshot generator APIs that can help. ### Urlbox If you're looking for an easy way to take screenshots of websites automatically, you'll love the Urlbox [website screenshot API](https://urlbox.com/screenshot-api.md). The tool allows you to generate screenshots from any website using a REST API that works with many programming languages. *See how to take* [*website screenshots with Java*](https://urlbox.com/website-screenshots-java.md)*.* With the Urlbox web page capture API, you can purchase access to one of the servers and simply call up the server with a URL (the address of the web page you'd like to take a screenshot of). Urlbox then returns an image of that URL in whatever format you prefer. This can be done through a simple HTTP GET request. Urlbox is a highly versatile API screenshot generator used by businesses that don't want to run their microservice, as the API can handle a large volume of requests daily. For example, Swiped.co uses Urlbox to create the web's [biggest Swipe file](https://urlbox.com/customers/swiped.md). ![](/content/website-screenshot-generator-tools-apis/image1.png) Our **pricing** starts at $19 per month for 2,000 requests. You can always start with a [7-day free trial](https://urlbox.com/pricing.md). ### Screenshotlayer Screenshotlayer provides a simple way to create these snapshots through an easy-to-use API endpoint where your users can generate their own screenshot of the page they are viewing. Screenshotlayer allows you to have the generated screenshots uploaded directly to your AWS S3 bucket, meaning that you can easily integrate it with your existing setup and manage the uploads yourself. The service can also generate high-quality, real-time screenshots more efficiently than most competitors. However, there are some features that Screenshotlayer doesn't support, such as blocking ads or clicking accept on cookie banners. Screenshotlayer.com offers a free trial for your first 100 screenshots, which means you can try it out before paying anything out of pocket. It also has three paid plans starting at $19.99 per month and a 20% discount if billed yearly. ## Website screenshot portfolio generator With an increasing number of digital marketing agencies, bespoke design studios, and freelance graphic designers and web developers operating in the digital sphere, it can be a challenge to present case studies and client work in a visually appealing way. ![](/content/website-screenshot-generator-tools-apis/image3.png) There are times when you might need to use screenshots to create a portfolio. For example, copywriters and graphic designers might want to show how they've improved the design and flow of a website by changing the text. Programmers might want to show off their ability to design functional and aesthetically pleasing interfaces. In those cases, some tools can help you create screenshots of your work with just a few clicks. These screenshot generator services save you time by automatically creating the screenshots for you at a fraction of the cost it would take to hire someone else to do it. Take a look at some of these handy tools—you may be surprised at how easy they make it! ### Stillio - Automatic screenshot capture and share Building a portfolio comprised of all the websites you or your agency has designed over the years can be daunting. You'll have to go over each webpage you created and save it as an image. Not to mention you'll have to do this process for the mobile and desktop versions of that page. This website screenshot generator allows you to input a bunch of URLs and screenshot them simultaneously. It lets you configure the width & height of the viewport and specify a custom user agent. Thus your final images will reflect the websites you created. Moreover, with Stillio, you can automatically send the screenshots to a 3rd party cloud service (like Dropbox or Google Cloud) or even sync to a webhook. **Best for agencies and companies** Stillio packs a variety of features that make the process of capturing screenshots a breeze, but it comes at a cost. Their cheapest plan starts at $29/month, which only lets you track up to 5 web pages. This is way more expensive and restrictive than Urlbox, where plans start at $19 and do not come with any restrictions regarding the number of different pages you can capture. You'll have to go for the $299/month plan if you want to track an unlimited number of web pages. Stillio is best suited for businesses and agencies that have created tens or hundreds of websites, so if you are part of a boutique agency or freelancer, the Full Page Screenshot Chrome Extension might be a better option. ### Full Page Screenshot - Chrome Extension This website screenshot generator is nothing but a Chrome Extension. Once installed and activated, it will generate an icon on your Chrome extension bar. To capture a full-page screenshot, you'll have to navigate to the website you want to capture and simply click on the Full Page Screenshot extension icon. The generator will start scrolling automatically through the webpage until it hits the footer and will open up your screenshot in a new window. After that, you'll be able to download the image as a PNG or PDF file to your computer. Although this is a free way of generating full-page screenshots, the tool is prone to errors, especially if the page you are trying to capture has sticky elements (like sticky buttons, sticky headers, etc.). You might need to edit the final image before adding it to your portfolio. You can use any of the tools I covered above to generate screenshots, but I did leave something special towards the end. The last part of the article focuses on solutions that require programming skills, so if you are a developer or willing to hire one, read on. Otherwise, you can pick one of the above generators. ## Automated website screenshots generator Before I jump into this, I want to share a word of caution. You should be aware that automated screenshot systems are only as good as the person who sets them up. If the system fails to run correctly or is set up incorrectly, you might lose records or end up with bad-quality screenshots. ![](/content/website-screenshot-generator-tools-apis/image2.png) With that out of the way, let's jump on the 2 of the most used automated website screenshot generators. ### Html2canvas Html2Canvas is a JavaScript library that creates screenshots of websites based on the DOM. To get started, you'll have to download the library from Github and include the html2canvas.js script at the `<head>` of the page you want to capture. You can read more about HTML2canvas in this [article](https://urlbox.com/html2canvas-vs-phantomjs-vs-urlbox.md). If you decide to use this library, you should consider that it doesn't capture an actual screenshot. Instead, it builds the screenshot based on the information available on the page. Keep this in mind and run tests before committing to this generator. ### PhantomJS PhantomJS is a headless web browser that allows you to capture web contents, including SVG and Canvas, programmatically. Even though it's still widely used by companies and freelance developers, it has a caveat: this service's development has been suspended since 2018. I highly recommend you start with another generator on this list. I consider PhantomJS an honorable mention in this list as it is extremely popular. StackOverFlow is full of answers you can skim through to get almost any information you need regarding PhantomJS. On the other hand, this can mean lots of time spent trying to get it working just the way you like, the time you should better spend doing other, more productive things. You can check out more about PhantomJS from this article that compares it with other [screenshot services](https://urlbox.com/html2canvas-vs-phantomjs-vs-urlbox.md). ## Urlbox - The best website screenshot generator Urlbox is the best website screenshot generator because it packs the full features of all other screenshot generators. You can use it to: - capture responsive website screenshots and create website portfolios - save the final images in a plethora of different file formats (including SVG, WEBP, and even HTML) - configure how the website you want to screenshot looks like even before you capture its web pages. The best part is that you can start using Urlbox for free for seven days before committing to a paid plan. Check out our [pricing page](https://urlbox.com/pricing.md) and pick the best option for the number of screenshots you need to take per month. --- # Best Website Thumbnail APIs To Automatically Generate Webpage Previews > This article will cover four of the best website thumbnail APIs you can use to automatically generate high-quality webpage previews. Source: https://urlbox.com/website-thumbnail-apis Last updated: 2025-03-21 --- A webpage preview is one of the first things people see when they come across a website shared on social media (or on [SERPs](https://www.searchenginejournal.com/google-thumbnail-images-in-serps/373783/)). These previews are proven to influence clickthrough rate, which means they should be high quality and have the correct aspect ratio. You can always create a featured image for each page if you are in charge of a small website, but things can get complicated as the number of pages grows. ![image3](/content/website-thumbnail-apis/image3.png) In this article, I will cover four of the best website thumbnail APIs you can use to automatically generate high-quality webpage previews. ## Urlbox - Best All-Around Website Thumbnail API Urlbox is a feature-rich [screenshot API](https://urlbox.com/screenshot-api.md) that lets you capture any webpage and export the final image in multiple formats (PNG, JPG, WEBP, SVG, etc.). ![image4](/content/website-thumbnail-apis/image4.png) Moreover, you can quickly integrate Urlbox with your app or website because it works with all major programming languages, or simply via a request URL: ``` https://api.urlbox.com/v1/{{API\_KEY}}/png?url=https%3A%2F%2Furlbox.com%2F5-website-screenshot-apis-for-your-business ``` The above request URL will generate [this image](https://api.urlbox.com/v1/ca482d7e-9417-4569-90fe-80f7c5e1c781/770e281e670c537c7a19bdf89fceb5a4c54af39f/png?url=https%3A%2F%2Furlbox.com%2F5-website-screenshot-apis-for-your-business) if you change the `{{API\_KEY}}` with a valid one. This screenshot was generated using only two parameters: ```json { "format": "png", "url": "https://urlbox.com/5-website-screenshot-apis-for-your-business" } ``` But Urlbox is capable of so much more. Your final thumbnail should display the page's actual content and nothing else, so if your website has a cookie banner or ads, you can automatically hide them with Urlbox. All you need to do is to append the appropriate parameters to the request URL, and your screenshot will be generated automatically. Here's how it would look: ``` https://api.urlbox.com/v1/Q83xEHeBytTeOQp3/png?url=https%3A%2F%2Furlbox.com%2F5-website-screenshot-apis-for-your-business&hide\_cookie\_banners=true&block\_ads=true ``` You can view all available options in the official [Urlbox documentation](https://urlbox.com/docs.md). Let’s explore some of the most commonly used features by people that generate thumbnails with Urlbox. ### Best Urlbox Features To Generate High-Quality Webpage Thumbnails Perhaps the best thing about Urlbox is the ability to generate a thumbnail based on a simple request URL. With the [Open Graph protocol](https://ogp.me/) (what Facebook, Twitter, and Linkedin rely on), you can simply use the request URL as the content of the `og:image` property. Once you have done that, you can check out your metadata using [LinkedIn's Debugger](https://www.linkedin.com/post-inspector/inspect/https:%252F%252Furlbox.com%252F5-website-screenshot-apis-for-your-business). In addition, Urlbox lets you: - delay when the screenshot is taken based on DOM load, when all requests have been finished, or a specific time in ms - scroll or click on a selector before the screenshot is taken - tunnel the request through a proxy - change the viewport size. These features (plus more) are available to you regardless of your plan. You can use Urlbox for [free for 7 days](https://urlbox.com/pricing.md) (no credit card needed). After your free trial ends, you can choose one of the four available plans starting at just [$19 per month](https://urlbox.com/pricing.md). This will let you generate up to 2,000 monthly screenshots, which is more than enough for a small business. Urlbox caches screenshots for up to 30 days, which makes the Starter plan the best option if your website has fewer than 1000 pages. Moreover, no request will be made if a page is not shared during a month. On the other hand, if a page is shared multiple times during the same month, there will be only one request made, as Urlbox has already chaced the screenshot. You can view all available plans on the [pricing page](https://urlbox.com/pricing.md). ## PagePeeker - Cheap Website Thumbnail API PagePeeker is perhaps the cheapest thumbnail generator API in this list. It can work great for businesses looking for a quick way to generate thumbnails, but it lacks some important features. ![image1](/content/website-thumbnail-apis/image1.png) ### PagePeeker Features With pricing plans starting at $5.99 per month for up to 100,000 API calls, PagePeeker is by no means an all-in-one screenshot tool. Nevertheless, it can help you generate a lot of thumbnails as long as you don't need any extra functionality. PagePeeker's API lets you save the final screenshot in 5 different predefined image sizes, starting from 90 by 68 pixels to 480 by 360 pixels. With that in mind, you should pick a different API if you plan to use the thumbnails for social media sharing. Their cache the screenshots for up to 7 days on the cheapest plan ($5.99 per month) and for up to 5 days on the more expensive one ($39.99 per month). In addition, it can take anywhere between 10 and 20 seconds for PagePeeker to generate the screenshots from your target webpage. If you go with the custom-priced Premium plan, your thumbnails will be generated in under 5 seconds. ### PagePeeker Drawbacks Perhaps the biggest drawback of PagePeeker is the inability to specify custom viewport dimensions. This means that your thumbnails can get distorted on social media, not to mention the poor final image quality. Moreover, PagePeeker can capture full-page screenshots and mobile and tablet screenshots, but you will need a custom-priced plan to unlock this functionality. ## ThumbnailWS - Free Website Thumbnail API ThumbnailWS is the only API on this list (and perhaps in the whole market) that provides a free plan. It packs some basic features you need to generate thumbnails, although you must go with a paid plan to unlock extra functionality. ![image5](/content/website-thumbnail-apis/image5.png) ### ThumbnailWS Features Going with ThumbnailWS's free plan allows you to create up to 1000 thumbnails each month. You can specify the final image width and a delay, in milliseconds, between 0 and 5000 (2.5 seconds by default), and that's it. Their paid plan goes for $49.50 per month and lets you make up to 2.5 million monthly requests. At the same time, this plan lets you capture full-page screenshots and emulated mobile screenshots. Alternatively, you can manually specify the viewport before ThumbnailWS generates the final image. You can also save the final image in either JPEG (default) or PNG. ### ThumbnailWS Drawbacks Like most screenshot APIs, ThumbnailWS cannot hide cookie banners or correctly render flexbox content. It can work great for a simple WordPress website, but it struggles with anything more complex. ThumbnailWS can only generate HD images (up to 1280 x 720 px), which can be a deal breaker if you need higher-quality thumbnails. ## ThumIO - Animated Webpage Thumbnail API ThumIO does something that the others in this list can not, it has the option to animate the final image. This is a great functionality if you want to screenshot a webpage with moving elements, but it's not something most people will ever use. ![image2](/content/website-thumbnail-apis/image2.png) ### ThumIO Features Besides animating screenshots, ThumIO packs more functionality compared to the last two APIs but still doesn't come close to Urlbox: - you can specify the width of the final image - export the final image in PNG, JPG, or PDF formats - set up a delay before the screenshot is taken - capture a full-page screenshot. ThumIO's pricing is slightly different from the previous models, as you will pay for how many requests you make each month, with the minimum starting at $1 per month for 1000 screenshots. ### ThumIO Drawbacks As cheap as this seems, you must know that it has certain drawbacks, as your screenshot will have the Thum.io Branded Loader. At the same time, this plan doesn't allow you to configure the viewport width or capture a full-page screenshot. Regardless of the plan you choose, you should keep in mind that ThumIO struggles to render some complex websites and can't hide cookie banners and ads. ## What Is The Best Website Thumbnail APIs? The best website thumbnail API is the one that works best for your specific use case: - if you want to save funds and run a simple website, then PagePeeker might be your best option - if you want animated screenshots with animated loaders, then you should go with ThumIO - but if you want an all-in-one screenshot generator that can correctly render any website, hide cookie banners and ads, and generate retina-ready images, then [Urlbox](https://urlbox.com/pricing.md) is your best choice. --- # Animated Screenshots > Create animated screenshots of your app with a single command. Source: https://urlbox.com/animated-screenshots Last updated: 2022-11-29 --- Some screenshots don't give a real sense of how a website looks and feels to its visitors. Take this one of TypeForm: ![Static screenshot of Typeform](/content/animated-screenshots/image1.png) "You don't want to make a boring form" but this screenshot looks a bit... boring. Wouldn't it be nice to capture the page as Typeform's designers meant for it to be experienced? How about like this? ![Animated screenshot of Typeform](/content/animated-screenshots/image2.gif) That 10 second video was generated with the following code: ```shell curl -X POST \ https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer YOUR_URLBOX_API_SECRET' \ -H 'Content-Type: application/json' \ -d '{"url":"https://typeform.com","format": "mp4","delay": 10000}' ``` The default video length is 3 seconds. We've added a 10,000 millisecond delay making the length 10 seconds. This feature is currently in beta. As you can imagine it's quite a bit more resource intensive compared to rendering screenshots. During the beta the cost will be exactly the same as a screenshot render. Please take it for a spin but expect costs to increase in 2023. --- # Block pop ups and hide cookie banners from screenshots > Several solutions for removing these annoying banners and making your screenshots look a lot cleaner. Source: https://urlbox.com/block-pop-ups Last updated: 2022-11-02 --- Have you been frustrated by cookie banners and other popups spoiling your screenshots? ![a spreadsheet of URLs](/content/block-pop-ups/cookiebanners.jpeg) At Urlbox, we have several solutions for removing these annoying banners and making your screenshots look a lot cleaner. ## 1. Set `hide_cookie_banners=true` When setting hide\_cookie\_banners=true in your Urlbox request, we will use various methods to try and detect these modals and hide them using css. ## 2. Set `click_accept=true` click\_accept=true, will attempt to remove cookie banners from screenshots by clicking on the most likely 'accept cookies' button that we detect. ## 3. Set `press_escape=true` press\_escape=true, does what you would expect and simulates a button press of the Escape key - we have found that quite a few modals can be removed using this method! ## 4. Set `hide_selector` With the hide\_selector option, you can pass in a comma-separated list of css selectors that will be hidden in the screenshot. ## 5. Run custom js and/or css You can run custom js and / or css, if you want to run your own algorithm for finding and detecting modals, or you have a bunch of styles that should tame the most common popups. --- # Bulk screenshot generation with Urlbox > Grab screenshots from a list of 100s of URLs Source: https://urlbox.com/bulk-screenshots Last updated: 2022-11-03 --- Have you ever wanted to grab screenshots from a list of 100s of URL's stored in a spreadsheet? Great news: with the Urlbox Zapier integration, you totally can, and it only takes a few minutes to get started. ## Step 1: Let's assume you have a spreadsheet with a list of URLs, one on each row: ![a spreadsheet of URLs](/content/bulk-screenshots/step1.png) ## Step 2: Create the following zap in Zapier: ![Zapier zap with trigger and two actions](/content/bulk-screenshots/step2.png) Be sure to feed the URL column from the first step, into the URL input of the Urlbox action. ## Step 3: ![screenshots in Google Drive](/content/bulk-screenshots/step3.gif) Run the zap, and check your screenshots in google drive: You can also use our Zapier integration to [schedule screenshots every hour/day/month](https://urlbox.com/automated-screenshots/automate-website-screenshots-schedule.md) etc. --- # How to extract custom metadata > Get any data you want from a page at the same moment as taking a screenshot Source: https://urlbox.com/custom-metadata Last updated: 2022-11-15 --- Knowing all the bog standard metadata for a screenshot isn't enough information for everyone. Saving the HTML and parsing it server side is one option. But that takes time and can be a memory intensive pain to do at scale. What if you could get any data you want from a page at the same moment your screenshot is being taken? We've supported the execution of custom JavaScript with Urlbox for years. Now that JavaScript can return data to you by assigning a value to a special variable window\.customUrlboxData. Here's an example of a simple request you could make including some JavaScript you'd like us to execute: ```bash curl -X POST \ https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer YOUR_URLBOX_API_SECRET' \ -H 'Content-Type: application/json' \ -d '{"url":"https://www.bbc.co.uk/news/technology-63635380", "metadata": true, \"js": "window.customUrlboxData = {h1: document.querySelectorAll(\"h1\")[0].textContent}"}' ``` It results in a response like the following: ```json { "renderUrl":"http://renders.urlbox.com/urlbox1/renders/...png", "size":608845, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299, "metadata":{ "author":"BBC News", ... "custom":{ "h1":"Google to pay record $391m privacy settlement" } } } ``` You can view the [full set of json here](https://mygrabs.s3.amazonaws.com/renders/2022/11/15/c57af67e-56f3-4fcc-ac83-22d2e6608b86.json). --- # Website screenshots with Apple-style emoji > Render emoji exactly as they look on your iPhone, iPad or Mac Source: https://urlbox.com/emoji Last updated: 2022-02-28 --- If you have attention to detail, one of the most frustrating things about taking automated website screenshots is emoji support. Urlbox solved this problem years ago along with dozens of [features for taking screenshots at scale](https://urlbox.com/features.md). ## Rendering emoji at a URL just works with Urlbox. Lets try rendering all the people emojis at [https://emojipedia.org/people/](https://emojipedia.org/people/.) We've set a few options extra to make this screenshot look great. We automatically click accept on Emojipedia's cookie popup, we reduce the screen size and ensure retina quality. ```html <img src="https://api.urlbox.com/v1/[API_KEY]/png?url=https%3A%2F%2Femojipedia.org%2Fpeople%2F&click_accept=true&height=480&retina=true&width=640" /> ``` It results in a screenshot like this: ![Example HTML rendered as a PNG](/content/emoji/image1.png) ## All the rendering options you need There are dozens of [rendering options in the Urlbox API](https://urlbox.com/docs/options.md). ## You're not limited to PNG Urlbox has many output formats beyond PNG. You can also render: - JPEG - WebP - SVG - AVIF - HTML (after JS has executed) - JSON (Coming soon). ## More Urlbox Features Urlbox is powerful with dozens of [features for taking screenshots at scale](https://urlbox.com/features.md). If you found this useful you might also want to checkout some of our other popular Urlbox features: - [URL to PNG](https://urlbox.com/url-to-png.md) - [URL to PDF](https://urlbox.com/url-to-pdf.md) - [HTML to PNG](https://urlbox.com/html-to-pdf.md) - [HTML to PDF](https://urlbox.com/html-to-pdf.md) - [Webfont support](https://urlbox.com/webfonts.md) --- # How to extract text from webpages > Get text in markdown format from a page at the same moment as taking a screenshot Source: https://urlbox.com/extracting-text Last updated: 2023-05-12 --- If you’ve ever tried extracting useful text from webpages you know it can be a nightmare. Removing all the code that makes text difficult to read. Retaining just enough markup and spacing that keeps the text readable. Ignoring the supporting parts of the page, such as navigation, if and when it gets in the way. All of this is even more important when working with LLMs such as OpenAI’s GPT. You need to keep within token limits while controlling the cost and performance. You know Urlbox is and always will be primarily focused on providing website screenshots you can depend on: - The most accurate renders, resilient to the worst crimes against HTML & CSS. - The most powerful features, reliably generating the images you want at scale. - The fastest possible response times, without compromising your infrastructure’s security or your customers privacy. It turns out all those things make a huge difference when extracting text. Urlbox customers have been using our [HTML output feature](https://urlbox.com/s3.md) to grab content with their screenshots for years. Last year we added [metadata extraction](https://urlbox.com/metadata.md) to remove a processing step. Soon after we added [custom metadata](https://urlbox.com/custom-metadata.md) to ease data extraction with JavaScript. Today you can try out our latest feature. Introducing markdown output. Just as with our HTML output feature, there are two ways to get markdown output from Urlbox: 1. Set the format to md ``` https://api.urlbox.com/v1/[API_KEY]/md?url=example.com ``` 2. Set the save\_markdown option ```bash curl -X POST \ https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer YOUR_URLBOX_API_SECRET' \ -H 'Content-Type: application/json' \ -d '{"url":"https://example.com", "save_markdown": true}' ``` You'll then get a response like this: ```json { "renderUrl":"http://storage.googleapis.com/...fad77fa39.png", "markdownUrl":"http://storage.googleapis.com/...fad77fa39.md", "size":30499, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299 } ``` You can save markdown along with a screenshot/pdf, html and metadata all in one request and straight into your own S3 bucket if you prefer. It works great with our webhooks feature too. We've also created a free tool at [url2text.com](https://url2text.com) where you can try it out in the browser. It's perfect for copying & pasting page content into ChatGPT. ![a screenshot of URL2Text.com](/content/extracting-text/url2text.png) We'll soon be adding some additional options to help reduce the number of characters/tokens in the returned markdown. Please let us know what you'd like to see first. We can't wait to hear what you build with it. This is the first of the features we're working on to support your work integrating AI into your software. We already have a [ChatGPT Plugin](https://urlbox.com/chatgpt-render-screenshots-html.md) available. And there's more to come. --- # GPU Accelerated Website Screenshots > Render complex webpages faster with a hardware GPU. Source: https://urlbox.com/gpu Last updated: 2022-12-07 --- Many of the most beautiful webpages these days are graphics heavy and often include WebGL scenes. Your MacBook takes rendering them in its stride but servers aren't usually built for the same kind of work. This can make rendering slow, and/or inaccurate - especially if you're doing a full-page render. Now with Urlbox you can get similar amounts of power by simply passing the following new option: ``` gpu=true ``` We'll then render the screenshots with a hardware GPU. We've seen instances of screenshots rendering 5x faster this way. This feature is currently in beta. GPUs are in high demand and significantly increase our costs.

Source: https://urlbox.com/detect-website-changes Last updated: 2025-11-26 --- CaptureDeck lets you automate and schedule screenshots. If you haven't checked it out yet, [click here to sign up](https://capturedeck.com/). We've added a comparison tab to CaptureDeck that makes it simple to spot differences between consecutive captures of your web pages. **Slider View** lets you slide left and right between your current and previous captures. This is perfect when you want to see the overall before/after: ![slider view](/content/image-comparison/slider-view.png) A great way to test this out is to choose a site that you know A/B tests or has moving banners. **Diff View** highlights exactly what changed, marking the differences from your last capture in magenta. This makes it easy to spot text updates, moved elements, a completely different height screenshot, or subtle changes: ![diff view](/content/image-comparison/diff-view.png) We've already found these quite useful for ourselves, testing out different presets and different webpages to see how much they differ from capture to capture. Getting image comparison right was surprisingly tricky, and it probably needs continual refinement to get it just right for everyone's use cases. Below I do a bit of a deep dive into the different image comparison methods and why we settled on one called [SSIM](https://en.wikipedia.org/wiki/Structural_similarity_index_measure). *** ## Deep Dive: Implementing SSIM in Ruby I had only ever consumed packages that other developers have made in the realm of image diffing (IE [Pixelmatch](https://github.com/mapbox/pixelmatch?tab=readme-ov-file)). Usually doing a simple pixel-by-pixel comparison of brightness is enough, but for this I needed something written in Ruby that compares images more like a human would and less like a computer would. Since there was nothing easily available, I experimented with a few methods, then ended up implementing a version of the SSIM method. I'm not a maths head at all, I often get simple addition wrong, so I decided to break this down in terms that my GCSE-maths brain circa 2011 can just about cope with. ### The Use Case As a user I want to know about changes that are actually material, like changed content. I don't want to be told that there's a 100% change between two screenshots just because a cookie banner with a slightly darker overlay is present. I also don't want to be told there's a change if the devs at the webpage I'm screenshotting decide that their background shouldn't be #FFFFF, but #FFFFE instead. Notable changes I adopted for this were changes like 'new landing page refresh' or 'new sales tactics' or 'new line of products out', where content on a page is actually new. Here's an example of a simple pixel-wise comparison failing this test: ![A pixel-wise diff marks a cookie-banner overlay as a 100% change, despite the underlying page being the same](/content/image-comparison/bad-pixelwise.png) You can see here that I needed something more tailored. I needed to find something that reduced these false positives but still showed actual content changes. Also, something nerdy enough to be useful, not so nerdy that it becomes incomprehensible. Most of my inspiration for this pulled from [Jeff Kreeftmeijer's Gist](https://gist.github.com/jeffkreeftmeijer/923894) on comparing images and creating image diffs. He discusses using ChunkyPNG and Ruby to implement various diffing methods. Here's a summary of some of the methods he describes: 1. Pixel-by-pixel comparison This is probably the method your flavour of ✨ *Agentic AI* ✨might spin up without thinking twice. It takes pixels in matching locations, compares them for brightness difference, and from that generates a score. It's good for something quick, and particularly for visual regression tests. It's not so good at a more human-like comparison, as you saw in the screenshot above. It can't tell the difference between slightly darker pixels and completely different coloured pixels (IE it thinks two colours are the same if they have the same brightness). 2. Using the Colour Difference Metric [(ΔE (Delta E) CIE76 standard)](https://uk.mathworks.com/help/images/ref/deltae.html). This is an extension of the pixel by pixel comparison, but instead of calculating using a simple 'is this pixel brighter' comparison, it calculates the difference in colour of each pixel using Euclidean distance in RGB instead. Think about the RGB spectrum placed on the XYZ axis. You take the difference between the R values, the G values, and the B values, then blend those differences into one number that represents “how different is the colour overall”, giving one diff value. This does solve for images that are ever so slightly darker/lighter, as it places it's scoring more on colour than just brightness. *** ### What Is SSIM I could have used the colour difference metric. However, when I experimented with a few image comparisons such as the one above with cookie banners and darker overlays, the accounting it did for brightness was still too sensitive. It would still think there was a massive difference in images when the content was almost entirely the same. I needed a different angle and found SSIM. It took me more time than I'm willing to admit to understanding it. SSIM essentially wants to answer the question 'do these look the same to a person' instead of 'are the pixels in these images the same'. It takes these three qualities: 1. Brightness (luminance): It checks whether both images have the same **average** brightness in a region. 2. Contrast: It checks how much the brightness **fluctuates** inside each region — whether the textures are smooth or sharp/detailed. 3. Structure: It measures whether those fluctuations rise and fall in the same **pattern**/alignment in both images — meaning the shapes and edges line up. Then, the formula combines the brightness comparison with the “contrast \* structure” comparison to produce one similarity score. A perfect match gives 1.0, completely different gets 0.0. If you look at page [606 of the paper](https://www.cns.nyu.edu/pub/eero/wang03-reprint.pdf) from 2004 when the method was created, you'll see the three formulas that make up the SSIM equation. I actually found the paper useful, but won't pretend I can understand the notation! What appeals to me about SSIM is that the brightness calculation is less of a key factor in the final score because structure and contrast are accounted for. Here's how it results with my cookie banner comparison, which is actually pretty darn close to what I'd hoped for: ![How SSIM comparison looks](/content/image-comparison/ssim-looks-good.png) What's great about this comparison is that though the cookie banner itself is still detected as a change, the darker overlay surrounding it isn't seen as a change. In my implementing this, I opted to use [ruby-vips](https://github.com/libvips/ruby-vips) instead of ChunkyPNG. ruby-vips is a wrapper around [libvips](https://github.com/libvips/libvips), written in C. ChunkyPNG is quite rudimentary compared: 1. ruby-vips handles more than just PNG's 2. It uses an optimised C library designed for this, rather than a single-threaded pure ruby implementation like ChunkyPNG 3. It is actively maintained. The last update to ChunkyPNG was in 2021 4. You don't have to run loops over pixels in the images, you run operations straight on the image. It's already optimised to do the heavy lifting. *** ### Step 1 - Luminance/Brightness comparison What this does is a touch different from exact pixel brightness comparison. It checks the **average brightness in the local neighbourhood of each pixel**. We blur the image first, to get an average brightness. I used a [Gaussian Blur](https://en.wikipedia.org/wiki/Gaussian_blur), which does pretty much that! If you've never seen what that looks like: ![img](https://upload.wikimedia.org/wikipedia/commons/thumb/6/62/Cappadocia_Gaussian_Blur.svg/960px-Cappadocia_Gaussian_Blur.svg.png) Here's the code I used to replicate it in Ruby. Converting the pixels to floats first gets a more accurate measurement: ```ruby blur_radius = 1.5 # what they used in the SSIM paper page 606. # Convert to grayscale image1 = img1.bands > 1 ? img1.colourspace("b-w") : img1 image2 = img2.bands > 1 ? img2.colourspace("b-w") : img2 # Convert to floats image1 = image1.cast("float") image2 = image2.cast("float") # the average brightness in a small local neighborhood around each pixel # We blur the image slightly to get the "local average" brightness mean1 = image1.gaussblur(blur_radius) mean2 = image2.gaussblur(blur_radius) ``` And just like that, we have our **local mean average brightness** for each image. *** ### Step 2 - Contrast Match The next step is to get the contrast score of the images which involves using brightness². I needed to really simplify this down to understand how in tarnation we get contrast from brightness. Here's my best explanation: If neighbouring pixels in an image have similar values, you'd consider that area smooth. like a nice smooth fading colour gradient. That could be represented as an array of pixels like this: Region A: ```ruby [90, 91, 92, 90, 93] ``` However, if neighbouring pixels have contrasting values, you know you've likely hit an edge of something or a texture or detail change. If you've ever used photoshop to remove the background on an image, you can probably imagine those pixelised edges. The array representation for that could be: Region B: ```ruby [0, 200, 10, 220, 5] ``` To calculate contrast, take the value of the pixels *squared*, then perform the *same* gaussian blur from step 1. If you just took the average brightness of these both without squaring them, you'd get 91 and 87, so we would think they're pretty much the same, which is why squaring it is so important. If you square each of the pixels IE you run `0x0, 200x200, 10x10, 220x220, 5x5` first, it makes those bigger values explode and come out of the woodwork, highlighting variation over just average brightness. Region A squared: ```ruby [8100, 8281, 8464, 8100, 8649] ``` makes a mean average of 8319. Region B squared: ```ruby [0, 40000, 100, 48400, 25] ``` makes a mean average of 17700. I've used a simple mean in the above example, but SSIM uses a weighted average IE the values above are averaged using a Gaussian blur. The key takeaway is the same, you get an amplified diff, showing you **contrast**. *** So to complete Step 2, we use the grayscale images from Step 1 and the average brightness maps from Step 1 and: ##### **1. Square the original grayscale image first, then blur it** This gives us the Gaussian-weighted average of the squared pixel values — the “local squared brightness.” This is literally step 1 but we square the image pixels first to highlight contrast. ```ruby (image1 * image1).gaussblur(blur_radius) (image2 * image2).gaussblur(blur_radius) ``` ##### **2. Take the average brightness from Step 1 (luminance/brightness) and square that** ```ruby (mean1 * mean1) (mean2 * mean2) ``` ##### **3. Subtract the two** The difference between these two steps tells us how much each image varies individually. That variation is SSIM’s measure of contrast. Here's the code: ```ruby variance1 = (image1 * image1).gaussblur(blur_radius) - (mean1 * mean1) variance2 = (image2 * image2).gaussblur(blur_radius) - (mean2 * mean2) ``` ### **Step 3 — Structure Match** In Step 1 we got **brightness**. In Step 2 we got **contrast**. Now we want to know **Do the two images vary in the same way?** Or in other words: **is the contrast aligned?** You could think of this like two sound waveforms. You’re not asking how loud each one is (contrast), but whether the waves *rise and fall together* in the same places (structure). Here's how we do it: 1. Multiply corresponding pixels together ```ruby (image1 * image2) ``` The first part of the calculation uses pixel-by-pixel multiplication *between the images* to see whether both images brighten or darken at the same places. Multiplying pixels is a way to detect **co-movement**: - **Big \* big = very big** Both images are bright in that spot → likely the same structure. - **Small \* small = small (but still positive)** Both images are dark in that spot → still aligned → structure likely matches. - **Big \* small = medium-ish** One image bright, one image dark → not aligned → weak structure match. The multiplication highlights where the two images are both rising or both falling, and it downplays places where they behave differently. 2. Blur that using the same Gaussian window ```ruby (image1 * image2).gaussblur(blur_radius) ``` We do this so the result isn't as noisy, just like with our other Gaussian blur steps. 3. Subtract the product of the two means (putting it all together). ```ruby covariance = (image1 * image2).gaussblur(blur_radius) - (mean1 * mean2) ``` Up to this point, the structure calculation gives false positives in places where we expect no structure at all. Imagine a page with the brightest #FFFFF shade background. The kind that burns your retinas. There's 0 structure there, we humans know that, but this method thinks there's a structure match. So we need to remove that part from the equation, which is what the above does. `mean1` and `mean2` from Step 1 give us the **average brightness** of each neighbourhood in the two images. These are already-blurred brightness values, so if both images happen to have a bright region, their means will *also* be bright. Imagine those means look like this: Mean of Image 1: ```ruby [250, 252, 251, 250, 249 ...] ``` Mean of Image 2: ```ruby [248, 251, 252, 249, 251 ...] ``` Multiply those together: ```ruby [62_000, 63_252, 63_252, 62_250, 62_499 ...] ``` These are massive numbers, so it tells us that area is expected to be quite bright anyway, and there's really no structure to take interest in. By subtracting these numbers from the structure match up to now, we remove those areas we expect to be bright, and what’s left shows that *extra* bit of rising and falling we actually care about. ### Putting it all together Now we just need to plug all of these numbers into the final SSIM equation. We multiply the brightness match by the contrast and structure match, then use a denominator to help generate something stable between 0 (no match) and 1 (exact match). We use constants to avoid instability when either the brightness map is super dark (near 0) or when there's little variance in contrast and structure. I follow the original SSIM paper's equation for this: `Instability Constant = (Stability factor * 255) squared.` 255 is the dynamic range of the pixel values for 8-bit grayscale images. They set the stability factors in the paper, and mention that their somewhat arbitrary, and the performance of SSIM is fairly insensitive to anything different. Have a read of the paper, it's a real bedtime page turner. Here is the final method: ```ruby LUMINANCE_STABILITY_FACTOR = 0.01 CONTRAST_STABILITY_FACTOR = 0.03 LUMINANCE_CONSTANT = (LUMINANCE_STABILITY_FACTOR * 255)**2 CONTRAST_CONSTANT = (CONTRAST_STABILITY_FACTOR * 255)**2 BLUR_RADIUS = 1.5 def ssim_map(img1, img2) image1 = img1.bands > 1 ? img1.colourspace("b-w") : img1 image2 = img2.bands > 1 ? img2.colourspace("b-w") : img2 image1 = image1.cast("float") image2 = image2.cast("float") mean1 = image1.gaussblur(BLUR_RADIUS) mean2 = image2.gaussblur(BLUR_RADIUS) variance1 = (image1 * image1).gaussblur(BLUR_RADIUS) - (mean1 * mean1) variance2 = (image2 * image2).gaussblur(BLUR_RADIUS) - (mean2 * mean2) covariance = (image1 * image2).gaussblur(BLUR_RADIUS) - (mean1 * mean2) numerator = (mean1 * mean2 * 2 + LUMINANCE_CONSTANT) * (covariance * 2 + CONTRAST_CONSTANT) denominator = (mean1 * mean1 + mean2 * mean2 + LUMINANCE_CONSTANT) * (variance1 + variance2 + CONTRAST_CONSTANT) numerator / denominator end ``` And boom, in 12 lines of code I have something like an SSIM map. Shame this isn't already implemented but it was a fun thought exercise. SSIM works pretty well for this use case, but one weakness is that you can get false diffs when an image shifts/translates by a pixel or two to the left/right/top/bottom. Complex Wavelet SSIM solves this as it's designed to recognise the same structure even when the image moves slightly. Another weakness is that though it ignores these pesky darker overlays I've been trying to ignore, it will still think some text in that region has changed. Annoying, but like I said before this will likely be refined as we go on. ## Sample Repo I made something to illustrate the different image comparison methods I tried.

In the sandbox we have a HTML option where you can try this out: ## Step 1: Create your HTML snippet and copy and paste it into the HTML textbox: ![a spreadsheet of URLs](/content/image-from-html/html.png) ## Step 2: Hit render ## Step 3: Download your generated image! ![a spreadsheet of URLs](/content/image-from-html/image.png) Now, because Urlbox is first and foremost an API, you can hook all of this up in the coding language of your choice and automate things like social media graphics, open graph images, sending custom invoice email PDFs or generating advertising assets. There are many possibilities! Not a coder? The [zapier](https://urlbox.com/zapier.md) no-code integration also makes all of this possible. --- # AI Screenshot Analysis with LLM Structured JSON Outputs > Use LLM structured outputs to get consistent JSON responses when analysing renders with AI providers like OpenAI, Anthropic, Google Gemini, and more. Source: https://urlbox.com/llm-structured-output Last updated: 2025-11-13 --- Getting consistent, structured responses can be challenging when analysing your screenshots, metadata, markdown, or HTML. Doing so is crucial for building reliable applications that depend on Urlbox's screenshot API and AI. Raw text responses from LLMs can vary widely, making them harder to parse and integrate into your workflow. That's why we've added support for **LLM Structured Outputs** to Urlbox. Whether you're building competitive intelligence tools, automating landing page optimization, or creating web automation workflows, structured outputs make it easier to extract insights from rendered pages. **Bonus** – PDF renders are now supported for both OpenAI and Anthropic. Plus, you can now give your LLM a system prompt like this: ```json { "llm_system_prompt": "You are an expert visual analyst. When given a screenshot, identify its purpose, layout, and key visual and textual elements. Describe what the image communicates, who it targets, and how effectively it delivers its message." } ``` ## What are Structured Outputs? Structured Outputs allow you to define a JSON schema that your AI provider (OpenAI, Anthropic) must follow when responding to a prompt. Instead of receiving unstructured text, you get predictable JSON that follows your schema. This makes it much easier to predict the LLM response and automate it into your own product. ## How it Works There are 2 new options to achieve a structured output when rendering with Urlbox: `llm_schema` is the [JSON schema](https://json-schema.org/docs) that you would like your structured output to abide by. By default, all you need to include is this option, and you'll get a JSON object response that accords with your schema. ```json { "llm_schema": { "Your": "JSON", "Schema": "Here" } } ``` The second option introduced is `llm_output`. This is optional (and set to object by default behind the scenes). Use this when you need the format of your response to be an array of objects or one in an enum of options. ```json { "llm_output": "object" | "array" | "enum" } ``` Using arrays is helpful when you want your model to analyse multiple elements on a page and return them in a single, structured JSON response — for example, when identifying several call-to-action buttons or product cards. The enum format, on the other hand, is best suited for simpler tasks that require a single categorical answer, such as classifying an image or determining the type of website. If you’re currently using options like `js` to extract specific data from pages — for example, grabbing text, links, or pricing using JavaScript during the render — you might find that structured LLM outputs can simplify your process. Instead of writing and maintaining custom JS for each use case, you can define a schema and let the LLM extract exactly what you need in a consistent format. It’s a more flexible and declarative way to get structured data, especially when your goal is analysis rather than manipulation. The three examples below assume you have already saved your LLM API keys in your project settings. They show partially omitted responses to highlight just the LLM response. ### 1. Object Output for Landing Page Analysis This is great for extracting specific data points from websites for competitive analysis and marketing intelligence. For example, you could summarise a landing page's core value proposition, identify key call to action elements, or analyse how a brand positions itself. Request: ```json { "url": "https://www.hey.com", "full_page": true, "use_llm": true, "llm_prompt": "Analyse this landing page screenshot as a marketing professional evaluating a competitor. Focus on what makes this page effective (or ineffective) at converting visitors into customers. Extract insights about their marketing strategy, positioning, and conversion tactics useful for competitive intelligence.", "llm_schema": { "type": "object", "properties": { "hook": { "type": "string", "description": "What immediately grabs attention and communicates value" }, "target_audience": { "type": "string", "description": "Who they're targeting based on visual/text cues" }, "differentiation": { "type": "string", "description": "How they position against competitors" }, "main_cta": { "type": "string", "description": "Primary call-to-action and its prominence" }, "social_proof": { "type": "array", "items": { "type": "string", "enum": ["testimonials", "logos", "numbers", "reviews", "case_studies"] }, "description": "Types of trust signals present" }, "conversion_score": { "type": "number", "minimum": 1, "maximum": 10, "description": "Likely conversion effectiveness (1-10)" }, "best_element": { "type": "string", "description": "Most effective aspect to copy" }, "biggest_weakness": { "type": "string", "description": "Main weakness or missed opportunity" } }, "required": ["hook", "target_audience", "differentiation", "main_cta", "social_proof", "conversion_score", "best_element", "biggest_weakness"] } } ``` Response (we tried it on Hey from 37 Signals): ```json { "llmResponse": { "response": { "result": { "hook": "Join more than 150,000 people who get our email newsletter.", "target_audience": "Tech-savvy individuals and privacy-conscious users looking for a new email solution.", "differentiation": "Emphasizes privacy, control over email, and innovative features like The Screener and Inbox.", "main_cta": "\"See how HEY works\" button prominently displayed.", "social_proof": [ "testimonials", "numbers" ], "conversion_score": 8, "best_element": "Strong emphasis on privacy and user control, supported by testimonials.", "biggest_weakness": "Lack of detailed pricing information on the landing page." } } } } ``` ### 2. Array Output for Multi-Element Analysis Use an `array` output when you need to analyze multiple similar elements on a page that share the same structure—like product cards, call-to-action buttons, or pain points. Each element will be returned as an object following your schema, all collected in a single array response. Request: ```json { "url": "https://www.figma.com/", "full_page": true, "use_llm": true, "llm_prompt": "Analyse this landing page by breaking it down into distinct sections (hero, features, benefits, social proof, etc.). For each section, evaluate its marketing effectiveness, what conversion goal it's trying to achieve, and what persuasion techniques it uses. Focus on what each section does well and how it could be improved.", "llm_output": "array", "llm_schema": { "type": "object", "properties": { "section_type": { "type": "string", "enum": ["hero", "feature", "benefit", "social_proof", "pricing", "faq", "cta", "footer"], "description": "Type of page section" }, "primary_message": { "type": "string", "description": "Main message or value proposition of this section" }, "target_audience": { "type": "string", "description": "Who this section is targeting (if specific)" }, "conversion_goal": { "type": "string", "enum": ["awareness", "consideration", "conversion", "retention", "support"], "description": "What stage of the funnel this section addresses" }, "persuasion_technique": { "type": "string", "enum": ["social_proof", "authority", "scarcity", "reciprocity", "consistency", "liking", "logical_appeal"], "description": "Primary persuasion technique used" }, "visual_prominence": { "type": "string", "enum": ["high", "medium", "low"], "description": "How much visual attention this section commands" }, "effectiveness_score": { "type": "number", "minimum": 1, "maximum": 10, "description": "How effective this section is at achieving its goal (1-10)" }, "key_strength": { "type": "string", "description": "What this section does particularly well" }, "improvement_opportunity": { "type": "string", "description": "Main way this section could be improved" } }, "required": ["section_type", "primary_message", "conversion_goal", "persuasion_technique", "visual_prominence", "effectiveness_score", "key_strength", "improvement_opportunity"] } } ``` Response (we tried this one on Figma): ```json { "llmResponse": { "response": { "result": [ { "section_type": "hero", "primary_message": "Think bigger. Build faster. Figma helps design and development teams build great products, together.", "conversion_goal": "awareness", "persuasion_technique": "logical_appeal", "visual_prominence": "high", "effectiveness_score": 8, "key_strength": "Clear and bold value proposition that immediately communicates the benefit of using Figma.", "improvement_opportunity": "Include a more specific call-to-action to guide users on what to do next." }, { "section_type": "cta", "primary_message": "Get started for free", "conversion_goal": "conversion", "persuasion_technique": "reciprocity", "visual_prominence": "high", "effectiveness_score": 9, "key_strength": "Strong call-to-action that lowers the barrier to entry by offering a free start.", "improvement_opportunity": "Add urgency or limited-time offers to increase conversions." }, { "section_type": "footer", "primary_message": "Learn how to use Figma", "conversion_goal": "support", "persuasion_technique": "authority", "visual_prominence": "low", "effectiveness_score": 6, "key_strength": "Provides resources for learning and support, enhancing user experience.", "improvement_opportunity": "Make the learning resources more prominent to encourage engagement." } ] } } } ``` ### 3. Enum Output for Website Classification Perfect for simple classification tasks: Request: ```json { "url": "https://my-favourite-shop.com", "use_llm": true, "llm_prompt": "Classify this website into one of the predefined categories", "llm_output": "enum", "llm_schema": [ "ecommerce", "blog", "news", "documentation", "social", "business", "portfolio" ] } ``` Response: ```json { "llmResponse": { "response": { "result": "ecommerce" } } } ``` These examples show what's possible when you combine visual analysis with structured outputs. **HTML, markdown, and metadata capture content, but they miss how it actually looks—the layout and design that determine how a page communicates. Structured outputs let you analyze the final rendered result, as if you had your own eyes on it, not just the underlying code.** You get consistent, predictable data from screenshots that's easier to work with than unstructured text responses. ## JSON Schema Validation All schemas are validated using the JSON Schema specification. We do not support `draft-04` JSON Schemas, and recommend using version `draft-07`. This ensures: - **Type Safety**: Your responses will match the expected data types - **Required Fields**: Specified fields will be present - **Data Validation**: Enums, patterns, and constraints are enforced - **Consistency**: Every response follows the same structure While structured outputs significantly improve reliability, AI providers like OpenAI and Anthropic still allow for some flexibility in formatting—so results may occasionally drift from your schema. ## Supported LLM Providers We support a wide range of LLM providers. Check out our docs page for the full list of 15+ supported providers including: - OpenAI (GPT-4o, GPT-4, etc.) - Anthropic (Claude models) - Google Gemini - Azure OpenAI - Mistral AI - Groq (fast inference) - And many more... ## Best Practices ### 1. Clear Descriptions Always provide clear descriptions for your schema properties: ```json { "properties": { "summary": { "type": "string", "description": "A 2-3 sentence summary of the main content" } } } ``` ### 2. Use Appropriate Types Match your schema types to your expected data: ```json { "price": {"type": "number"}, "available": {"type": "boolean"}, "tags": { "type": "array", "items": {"type": "string"} } } ``` ### 3. Set Required Fields Mark essential fields as required: ```json { "required": ["title", "url", "price"] } ``` ## Next Steps Ready to get started with structured outputs? 1. **Set up your LLM provider** in your project settings. 2. **Design your JSON schema** using the JSON Schema documentation, or programmatically with a validator tool. 3. **Test your schema** in the Urlbox dashboard sandbox. 4. **Integrate into your application** using our API Get consistent, structured AI analysis of your screenshots, PDFs, and other renders today with Urlbox LLM Structured Output. ## Want More? We’d love to hear from you. If you have an idea for an AI feature that your provider supports, and you'd like to see integrated into Urlbox, please do get in contact.

Happy Rendering 📸 --- # Extract Metadata with Screenshots > Get publisher, title, date, author and more with every one of your screenshots Source: https://urlbox.com/metadata Last updated: 2022-11-08 --- Knowing the URL and the time you took a screenshot isn't enough information when you have hundreds to organise each month. Especially when your URLs aren't very descriptive: ``` https://www.bbc.co.uk/news/technology-63539246 ``` Making another request to that URL to find out the title of the page and gather other data is one option. Sadly some pages change between requests and other pages are short lived. Either way you're doubling the amount of work that website has to do for you and potentially your costs too. What if you could get all this metadata (and much much more) for free with every one of your screenshots - all in one request? ``` "publisher": "BBC News", "title": "Ten days of Twitter chaos", "date": "2022-11-07T13:22:12.000Z", "author": "James Clayton", "description": "Elon Musk’s first week-and-a-half at Twitter has been a rollercoaster of big changes.", "favicon": "https://static.files.bbci.co.uk/core/website/assets/static/icons/touch/news/touch-icon-36.413a37b22764b74a2793.png", "image": "https://ichef.bbci.co.uk/news/1024/branded_news/833A/production/_127549533_twitter_cracked_bird_getty.jpg" ``` How about by simply adding?: ``` "metadata": true ``` You can now do just that with Urlbox. You'll need to make an API request that can respond with JSON. Here's an example curl request: ``` curl -X POST \ https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer YOUR_URLBOX_API_SECRET' \ -H 'Content-Type: application/json' \ -d '{"url":"https://www.bbc.co.uk/news/technology-63539246", "metadata": true}' ``` That's it. I won't include the full response payload here but you'll get a response structured as follows: ```JSON { "meta": { "endTime": "2022-11-08T12:34:17.033Z", "startTime": "2022-11-08T12:34:09.627Z" }, "event": "render.succeeded", "result": { "renderUrl": "https://renders.urlbox.com/urlbox1/renders/...png", "metadata": {"publisher": "BBC News", "title": "Ten days of Twitter chaos", ...}, "size": 123, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299 }, "renderId": "..." } ``` You can also use this with our [Webhook](https://urlbox.com/webhooks.md) and [S3](https://urlbox.com/s3.md) features. --- # Automate screenshots with n8n and Urlbox > Use n8n to automate website screenshots with 400+ app integrations Source: https://urlbox.com/n8n-integration Last updated: 2026-01-28 --- Urlbox now integrates with [n8n](https://n8n.io/). If you're already using n8n for workflow automation, you can add your renders directly into your workflow. Let's look at a common use case: you've got a Google sheet of URLs and you want screenshots of each one, with links saved back to the sheet. ### What we'll build A workflow that: 1. Reads URLs from a Google Sheet 2. Captures a screenshot of each URL using Urlbox 3. Writes the screenshot URL back to the spreadsheet ### Step 1: Set up your Google Sheet Create the example spreadsheet with your URLs in one column. Add a second column called 'Screenshot' which will hold the resulting location of the stored screenshot that we'll populate automatically. | URL | Screenshot | | ------------------------------------------------------------ | ---------- | | [https://stripe.com](https://stripe.com) | | | [https://tailwindcss.com/](https://tailwindcss.com/) | | | [https://www.crunchydata.com/](https://www.crunchydata.com/) | | | [https://urlbox.com](https://urlbox.com) | | | [https://capturedeck.com](https://capturedeck.com) | | | [https://apple.com](https://apple.com) | | | [https://rubyonrails.org/](https://rubyonrails.org/) | | ### Step 2: Create your n8n workflow In n8n, create a new workflow with the following nodes: #### Google Sheets Trigger Hit 'Add first step' and search for Google sheets, then select the Trigger 'On row added or updated'. ![The N8N menu when searching for Google sheets, showing where the trigger to be selected is](/content/n8n-integration/first-sheet-select.png) You'll need to set up your credentials for Google Sheets. Under 'credentials to connect with' you'll see an option to create one. If you can't login already using single sign on (SSO), you might need to take a look at [this guide](https://docs.n8n.io/integrations/builtin/credentials/google/oauth-single-service/?utm_source=n8n_app\&utm_medium=credential_settings\&utm_campaign=create_new_credentials_modal#set-up-oauth). Once your credential has been added, select the Google sheet you made (we named it n8n-urlbox), choose the first sheet, and set this trigger to execute when a row is added or updated. There's an extra option, 'Columns to Watch', which lets you specify the row to listen to for updates. Choose URL so the workflow only runs when one updates or adds a URL to the sheet. Hit 'fetch test event' and you should see the list of URL's you populated in the output, with the empty 'screenshot' column. ![The N8N config modal for Google sheets, illustrating the configuration setup for this example.](/content/n8n-integration/first-sheet-config.png) #### Urlbox Node Lets now go back in to the main workflow interface, add a new node connected to the Sheets trigger, searching for "Urlbox" in the node panel. ![The N8N menu when searching for Urlbox.](/content/n8n-integration/urlbox-node-select.png) Once clicked, select 'Take screenshot' from the available actions. Again, you'll need to configure your credentials for this, so grab your Urlbox secret key (found in your [dashboard](https://urlbox.com/dashboard)): ![The Urlbox dashboard showing where to find the secret key.](/content/n8n-integration/dashboard-secret.png) Create a new Urlbox credential (you're prompted from the N8N node if you've not made it before), pasting that key here: ![The N8N Urlbox credential modal where to place the secret key.](/content/n8n-integration/urlbox-credential.png) Once setup and assigned to the Node, you can drag the Triggered URL (under Google Sheets Trigger, looks like 'T | URL') into the Urlbox parameters' URL field like this: ![Showing the reader how it looks once the URL badge has been clicked and dragged into the URL parameter of the Urlbox config](/content/n8n-integration/urlbox-drag-url.png) And you'll see a dynamic field automatically populated, which should show you a previewed result of the first google sheet URL entry (in this case stripe.com). From here you can change the operation, allowing you to take anything from full page shots, to scraping HTML, smooth scrolling videos, or your own custom config using our [docs](https://urlbox.com/docs.md). You can also configure whether to receive the raw render/screenshot file or a storage location URL. We also have some additional options, like rendering HTML content you pass in, instead of a website URL, using a proxy server (super handy for difficult to load websites, such as when trying to take screenshots of social media), or adding your own options on top of the preconfigured operations. In this example make sure 'Download as file' is unchecked, so that you get back the temporary (30 day) storage location that can populate the Google sheet. If you actually want to use the above to store permanent locations to your renders, you should try out our [s3 feature](https://urlbox.com/docs/storage/configure-s3-private#configuring-s3) which automatically saves renders to your own desired cloud bucket. Alternatively, you could check 'Download as file' and use an S3 node to upload screenshots with the output Urlbox produces. Test it out by hitting 'execute step', and you should get back something like this: ![How the result of a test execution should look in the output section of the N8N Urlbox node](/content/n8n-integration/urlbox-test-result.png) #### Updating the same Google sheet with the results The last step we want to add is another Google sheets node. 1. Add a new node, search for Google Sheets, and choose the 'Append or Update row' action. 2. Add the credentials you created in the previous step. 3. For this example, choose the same document and sheet (default name is Sheet1). 4. By mapping each column manually by URL, dragging the Google Sheet trigger URL as the `URL (using to match)` value to send, then opening the 'Take screenshot' input on the left and dragging the `renderUrl` into the `Screenshot` value to send, the step will write the Urlbox renderUrl into that row’s Screenshot column. 5. optionally add the image function IE `=IMAGE("{{ $json.renderUrl }}")` in the screenshot row to populate, so that Excel pre-loads the image for each row, allowing you to see the image itself instead of a link. Here's how it should look: ![How the config of the second Google Sheet N8N node should be setup](/content/n8n-integration/second-sheet-config.png) Now it's time to go back to the workflow page and click 'Execute Workflow'. ![The workflow summary page on completion](/content/n8n-integration/workflow-summary.png) If all has worked, you should be able to refresh your Google Sheet in another tab and see that the screenshot columns have been ✨populated✨! Expand the rows and you'll see each screenshot populated in the row. You'll notice we don't need to place the Urlbox node inside a loop to iterate over every row in the Google sheet. N8N is smart enough to work that out for us! ![The workflow summary page on completion](/content/n8n-integration/google-sheets-result.png) ## What's Next The integration is available now on [npm](https://www.npmjs.com/package/n8n-nodes-urlbox) and through n8n's community node system. You can also read more about it on the [N8N website](https://n8n.io/integrations/screenshots-by-urlbox/). We'd love to hear how you're using the n8n integration. We'd also love to help you, so if you get stuck or have feedback or feature requests, just reach out through our support chat or email [support@urlbox.com](mailto:support@urlbox.com). Already using Zapier? Check out our [Zapier integration](https://urlbox.com/zapier.md) which offers similar functionality. Both integrations give you no-code access to Urlbox, so choose whichever platform fits your existing workflow. --- # Generate PDF documents from HTML with Urlbox > The full power of Urlbox's rendering engine so you and your designers can make beautiful reports. Source: https://urlbox.com/pdf-from-html Last updated: 2022-11-29 --- If you're already generating PDFs with Urlbox you're not alone. Our PDF feature is one of our most popular. It turns out much of the work required to make your screenshots excellent at scale also results in near-perfect PDFs. But there were a few bugs and missing features that needed ironing out. Now generating PDFs with Urlbox is better than ever and you might find it better than anywhere else. We've resolved some particularly hairy edge cases, especially for huge multi-page documents. We've heard other, (dedicated) PDF generating services, have flat out refused to handle some of the situations we now do. This is all you need do to make a two page PDF: ```shell curl -X POST https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer YOUR_URLBOX_API_SECRET' \ -H 'Content-Type: application/json' \ -d '{ "format": "pdf", "html": "<div class=\"page\"><h1>Page 1</h1></div><div class=\"page\"><h1>Page 2</h1></div>", "css": "div.page { page-break-after: always; page-break-inside: avoid;}"}' ``` You have the full power of Urlbox's rendering engine so you and your designers can make beautiful reports complete with anything you'd expect to render nicely in a browser. You can also find over a dozen [PDF-specific options](https://urlbox.com/docs/options.md#pdf-options) in our docs so you can make them just right. --- # Post HTML, CSS and JavaScript > Generate images from HTML on the fly without having to host it at a URL Source: https://urlbox.com/post-html-css Last updated: 2022-11-22 --- If you're generating images from HTML on the fly, you might not want to save the HTML anywhere. Hosting generated pages in a place that Urlbox can reach can also be challenging. What if you didn't need a URL for the things you want to turn into images? You can post HTML, CSS and even JavaScript to Urlbox. URLs not required! Here's an example: ```bash curl -X POST https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer YOUR_URLBOX_API_SECRET' \ -H 'Content-Type: application/json' \ -d '{ "html": "<div><h1 id=\"title\"></h1><p>Testing</p></div>", "js": "document.getElementById(\"title\").innerText=\"Hello World\"", "css": "div { padding: 10px; background-color: red } h1 { text-align: center; color: white } p {text-align: center; color: white}", "selector": "div", "width": "400", "height": "300" }' ``` It results in the following image: ![Image with white text centred on red back ground saying hello world testing](/content/post-html-css/369d4beb-9d39-4ea1-a1de-79c14da55953.png) You still have the full power of Urlbox's rendering engine so you and your designers can make far more beautiful images this way complete with fonts, emoji and anything else you'd expect to render nicely in a browser. --- # Save screenshots (and more) to S3 > Store a screenshots, HTML and metadata in your own s3 bucket Source: https://urlbox.com/s3 Last updated: 2022-11-15 --- The screenshots you capture and images you generate with Urlbox are valuable. You've of course paid us to render them. But the cost of the work your team have put into researching, developing and/or designing each one may be far higher. They might also include sensitive information that you want to keep privately. Almost all of our high volume customers now choose to store and distribute their screenshots and images from their own Amazon S3 account. This means they have access to them after our caches would normally expire. They can implement their own deletion policies and have complete control over how they can be accessed. When you choose to store a screenshot in your own s3 bucket we don't store a copy on our side. You can connect your own S3 account by adding a set of credentials and designating a bucket via the Urlbox Dashboard: ![Urlbox dashboard settings for S3](/content/s3/image1.png) You'll also need to ensure the designated S3 bucket has the right access policies applied. See the full S3 setup instructions linked from that page. Once correctly configured you can ensure your images are saved to S3 by including the following option in your request: `"use_s3": true` There are three other [storage options](https://urlbox.com/docs/options.md#storage-options) you've been able to use for a while: s3\_path, s3\_bucket and s3\_storageclass. But there's now more. You can also save the HTML of the rendered page and json with extracted metadata as well! Here's an example request: ```bash curl -X POST \ https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer YOUR_URLBOX_API_SECRET' \ -H 'Content-Type: application/json' \ -d '{"url":"https://www.bbc.co.uk/news/technology-63635380","use_s3": true, "save_metadata": true, "save_html": true}' ``` You'll get a response back like the following: ```JSON { "renderUrl":"https://mygrabs.s3.amazonaws.com/renders/2022/11/15/2cd22134-fc8d-4ca5-9ac4-8df3769bf340.png", "htmlUrl":"https://mygrabs.s3.amazonaws.com/renders/2022/11/15/2cd22134-fc8d-4ca5-9ac4-8df3769bf340.html", "metadataUrl":"https://mygrabs.s3.amazonaws.com/renders/2022/11/15/2cd22134-fc8d-4ca5-9ac4-8df3769bf340.json", "size": 123, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299 } ``` You are welcome to take a look at each of those URLs to see exactly what gets saved. You can also use this with our [Webhook feature](https://urlbox.com/webhooks.md). --- # Scrolling Website Screenshots > Create scrolling videos of long web pages programmatically Source: https://urlbox.com/scrolling-screenshots Last updated: 2022-12-14 --- Some websites are impossible to take full-page screenshots of. Scrolling triggers animations that change the page in ways that only make sense to be seen within the viewport. The iPhone 14 web page is an example of this. Here's a screenshot taken with our default settings: ![iPhone 14 web page](/content/scrolling-screenshots/image1.png) That's a fine screenshot but when you ask us to take a full page screenshot [the results are embarrassing](https://urlbox.com/content/scrolling-screenshots/image2.png.md). Sometimes it's just the most delightful aspects of a web page that are hard to show in a long narrow screenshot. You want screenshots that give users a sense of the experience they'd have if they viewed those websites. The team at Tailwind CSS get it. Checkout the [showcase](https://tailwindcss.com/showcase) they made (hover over each screenshot). What if you could show your users a scrolling screenshot like this: ![](/content/scrolling-screenshots/image3.gif) Now you can do just that programatically. With a few extra Urlbox options you can create videos that feel like someone recorded themselves scrolling down a page: ``` curl -X POST \ https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer YOUR_URLBOX_API_SECRET' \ -H 'Content-Type: application/json' \ -d '{ "url": "https://www.apple.com/iphone-14/", "format": "mp4", "gpu": true, "video_scroll": true}' ``` Note that we're using [gpu acceleration](https://urlbox.com/gpu.md) to ensure smooth and fast results. You can see the [MP4 generated by this code here](https://urlbox.com/content/scrolling-screenshots/image4.mp4.md). Video rendering, including GPU-accelerated scrolling, is generally available and priced the same as any other Urlbox render. See [pricing](https://urlbox.com/pricing.md) for details. ## Scroll to the sections that matter A constant top-to-bottom scroll is great for a landing page, but sometimes you want to visit specific sections and hold on each one for a set time, for example to walk through key features in turn or line the scroll up with a voiceover. `video_scroll_to` does exactly that: pass an ordered list of sections (a CSS selector or visible text) and Urlbox scrolls to each one in turn, pausing for a configurable wait before moving to the next: ``` curl -X POST \ https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer YOUR_URLBOX_API_SECRET' \ -H 'Content-Type: application/json' \ -d '{ "url": "https://urlbox.com", "format": "mp4", "video_scroll_to": ["#full-page-screenshots;wait=4s", "text=Screenshots at internet scale;wait=5s"] }' ``` Each stop's wait, scroll duration, easing and offset can be tuned individually, so you can pace the scroll precisely, for example to line it up with a voiceover section by section. If a target isn't found on the page, Urlbox holds position for that stop's full time slot rather than skipping ahead, so everything after it stays on schedule. For the full walkthrough see the [Recording videos guide](https://urlbox.com/docs/videos/recording-videos.md), and for every available option see the [video options reference](https://urlbox.com/docs/options.md#video-options). --- # Secure Screenshots with Zero Data Retention > Implementing secure screenshot and PDF generation in your application Source: https://urlbox.com/secure-screenshots Last updated: 2025-03-21 --- When building applications that handle sensitive data, screenshot and PDF generation can be a security challenge. Whether you're automating report generation from admin dashboards, creating design previews, or capturing user-specific content, you need to ensure that sensitive data remains protected throughout the process. [Website screenshot APIs](https://urlbox.com/screenshot-api.md) like Urlbox usually optimize for performance and ease of use through public CDN caching. While this works well for public content, it creates security risks when dealing with: - Internal dashboards containing user data - Financial reports with transaction details - Previews of unpublished content - Any other authentication-protected content As a result you might decide to build your own internal screenshot infrastructure using tools like Puppeteer or Playwright. But this comes with significant operational overhead in terms of infrastructure maintenance, updates, and scaling. **What if you could enjoy the ease of use and performance of a 3rd party screenshot API for your more sensitive renders?** That's exactly what Urlbox Secure Mode delivers - a zero data retention screenshot API. - Each request running in its own isolated browser instance - **Zero data retention** - all request data automatically purged within 90 seconds of the render completing - URLs, custom JS, and CSS are never retained beyond that window - No request logging of potentially sensitive parameters - No 3rd party storage or access to your renders ## Introducing Urlbox Secure Mode: Zero Data Retention Screenshots To use Secure Mode, set `secure_mode: true` in your API request and choose one of these storage approaches: 1. **S3-Compatible Storage Credentials** - Set `use_s3: true` if you've configured credentials in the Urlbox dashboard - Works with AWS S3, Cloudflare R2, Google Cloud Storage, DigitalOcean Spaces, MinIO, or any S3-compatible storage service. - Urlbox will ensure access is write only to your private bucket 2. **S3-Compatible Pre-signed URLs** - Provide a short lived `s3_presigned_url` for the primary screenshot/PDF. - And for additional output options (each requires its corresponding flag to be enabled): - `s3_presigned_url_metadata` with `save_metadata: true` - `s3_presigned_url_markdown` with `save_markdown: true` - `s3_presigned_url_html` with `save_html: true` 3. **Short Lived Content URL** - Provide a short lived URL with the `url` option to the HTML document you wish to screenshot or generate a PDF from. - Ensure the URL expires soon after the render is complete to minmise the chance of 3rd party access - Don't send HTML via the `html` option. You can learn more about our general security practices on our [security page](https://urlbox.com/security.md). Urlbox is [SOC 2 Type II certified](https://urlbox.com/blog/soc2-type-2-attested.md), and Secure Mode with zero data retention is part of our commitment to enterprise-grade security. Secure Mode is only availble to customers on Ultra, Business and Enterprise plans using the `latest` version of our rendering engine. Please Note: Due to reduced logging we are limited in the assistance we can provide to rendering issues when using Secure Mode. We recommend testing render options with non-sensitive content without including the secure\_mode option. If you'd like to learn more about this feature and get assistance in planning your implementation, we'd love to hear from you.

Rather than a screenshot of what you see in your web browser, you might encounter various challenges: - CAPTCHA or reCAPTCHA verification - Cloudflare Turnstile - Other security puzzles - Error messages - Unwanted redirects When you just need a handful of screenshots, it feels unfair. When you need thousands for your job, it's deeply frustrating. Wouldn't it be great if far fewer of your screenshots were blocked? Introducing the `use_stealth` option. If you're on one of Urlbox's Ultra, Business, or Enterprise plans, you can now send the option `use_stealth: true` with your screenshot requests. With this option enabled, Urlbox's headless browsers will behave more like regular desktop or mobile browsers, significantly reducing the chances of your screenshots getting blocked. **Important Note:** Do not use the `user_agent` option together with `use_stealth`, as this combination will create a browser fingerprint that is more easily detectable as automated traffic. This feature is currently available on the latest version of our rendering engine. Make sure to include `engine_version: latest` in your requests. Sadly this feature is not a silver bullet. Bot detection technologies are constantly evolving. We'll always work to try and keep up but 100% success is simply not possible. We're just getting started with more enhancements in this area. Are you encountering specific websites that are particularly challenging to screenshot? [Let us know](https://urlbox.com/contact.md) – our next update could be the one you've been waiting for. --- # URL to Image > Convert a URL into an Image in the favourite format for taking screenshots of websites. Source: https://urlbox.com/url-to-image Last updated: 2022-08-05 --- Turning a URL into an Image is one of the most common jobs developers use Urlbox for. Urlbox is powerful with dozens of [features for taking screenshots at scale](https://urlbox.com/features.md). The most basic request is as simple as forming a URL like the following: ```html https://api.urlbox.com/v1/[API_KEY]/png?url=example.com ``` Yes you can literally create an HTML image tag and it will render: ```html <img src="https://api.urlbox.com/v1/[API_KEY]/png?url=example.com" /> ``` Like this: ![Example HTML rendered as a PNG](/content/url-to-image/image1.png) However, you'll notice your API key is embedded in that URL. Anyone could potentially start using your API key to make requests against the Urlbox API - and use up your quota. So, if your Urlbox URLs are used publicly, you should prevent anonymous usage with an authenticated request format. [See how to do that in our docs](https://urlbox.com/docs/authenticated-requests.md). If want to generate your image tags for turning URLs into Images with code we've included examples of how you can do it in different languages below. ## URL to Image in Node.js ```js // npm install urlbox --save import Urlbox from "urlbox";

The most basic request is as simple as forming a URL like the following: ```html https://api.urlbox.com/v1/[API_KEY]/png?url=example.com ``` Yes you can literally create an HTML image tag and it will render: ```html <img src="https://api.urlbox.com/v1/[API_KEY]/png?url=example.com" /> ``` Like this: ![Example HTML rendered as a PNG](/content/url-to-png/image1.png) However, you'll notice your API key is embedded in that URL. Anyone could potentially start using your API key to make requests against the Urlbox API - and use up your quota. So, if your Urlbox URLs are used publicly, you should prevent anonymous usage with an authenticated request format. [See how to do that in our docs](https://urlbox.com/docs/authenticated-requests.md). If want to generate your image tags for turning URLs into PNGs with code we've included examples of how you can do it in different languages below. ## URL to PNG in Node.js ```js // npm install urlbox --save import Urlbox from "urlbox"; // Plugin your API key and secret const urlbox = Urlbox(YOUR_API_KEY, YOUR_API_SECRET); // Set your options const options = { url: "example.com", format: "png", }; const imgUrl = urlbox.generateRenderLink(options); // https://api.urlbox.com/v1/YOUR_API_KEY/TOKEN/png?url=example.com // Now set it as the src in an img tag to render the screenshot <img src={imgUrl} />; ``` ## URL to PNG in Ruby ```ruby # ruby gem coming soon require 'openssl' require 'open-uri' def encodeURIComponent(val) URI.escape(val, Regexp.new("[^#{URI::PATTERN::UNRESERVED}]")) end def urlbox(url, options={}, format='png') urlbox_apikey = 'YOUR_API_KEY' urlbox_secret = 'YOUR_API_SECRET' query = { url: url } query_string = query. sort_by {|s| s[0].to_s }. select {|s| s[1] }. map {|s| s.map {|v| encodeURIComponent(v.to_s) }.join('=') }. join('&') token = OpenSSL::HMAC.hexdigest('sha256', urlbox_secret, query_string) "https://api.urlbox.com/v1/#{urlbox_apikey}/#{token}/#{format}?#{query_string}" end url = urlbox("example.com", {}, 'png') puts url # url: "https://api.urlbox.com/v1/YOUR_API_KEY/TOKEN/png?url=www.google.com" ``` ## URL to PNG in PHP ```php // run this on the command line to install the urlbox php package: // composer require urlbox/screenshots use Urlbox\Screenshots\Urlbox; $urlbox = Urlbox::fromCredentials('API_KEY', 'API_SECRET'); // only required option is a url: $options['url'] = 'example.com'; // specify any other options to augment the screenshot... $options['width'] = 320; // Create the Urlbox URL $urlboxUrl = $urlbox->generateSignedUrl($options); // $urlboxUrl is now 'https://api.urlbox.com/v1/API_KEY/TOKEN/png?url=example.com&width=320' // Generate a screenshot by loading the Urlbox URL in an img tag: echo '<img src="'.$urlboxUrl.'" alt="Test screenshot generated by Urlbox">' ``` ## URL to PNG in Python ```python # PyPi package coming soon! #!/usr/bin/python import hmac from hashlib import sha256 try: from urllib import urlencode except ImportError: from urllib.parse import urlencode def urlbox(args): apiKey = "xxx-xxx" apiSecret = "xxx-xxx" queryString = urlencode(args, True) hmacToken = hmac.new(str.encode(apiSecret), str.encode(queryString), sha256) token = hmacToken.hexdigest().rstrip('\n') return "https://api.urlbox.com/v1/%s/%s/png?%s" % (apiKey, token, queryString) argsDict = {'url' : "twitter.com", 'thumb_width': 400} print(urlbox (argsDict)) ``` ## URL to PNG in Java ```java import java.io.UnsupportedEncodingException;

Keeping a request open for seconds when you're capturing loads of pages quickly adds up to minutes or hours spent waiting. What if your app could send us 30 screenshot requests in less than a second? Your app could get on with what it's doing while Urlbox does its thing. Now you can do just that by providing a webhoook endpoint for Urlbox to send your screenshot to. `"webhook_url": "https://example.com/your_webhook_url"` To keep overhead to a minimum you can (optionally) use a HEAD request like the following: ```bash curl -I "https://api.urlbox.com/v1/32a24502-34b4-4d10-9284-f678c9ff4a42/bef9d473d40cb491a8446e6fdeba2688ed672d2a/png?webhook_url=https%3A%2F%2Fexample.com%2Fyour_webhook_url&url=https%3A%2F%2Fwww.bbc.co.uk%2Fnews%2Fbusiness-63709754&format=png" ``` Then, a few seconds later you'll receive something like this at your webhook endpoint: ```json { "meta": { "endTime": "2022-11-22T11:13:30.400Z", "startTime": "2022-11-22T11:13:24.650Z" }, "event": "render.succeeded", "result": { "renderUrl": "https://renders.urlbox.com/urlbox1/renders/5799274d37a8b4e60496ce39/2022/11/22/4382ca89-4dd6-4b3e-8a58-07f5c0c0bf27.png", "size": 503502, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299 }, "renderId": "4382ca89-4dd6-4b3e-8a58-07f5c0c0bf27" } ``` If you use a POST request you'll probably want to use the asynchronous endpoint: `https://api.urlbox.com/v1/render` rather than the synchronous one: `https://api.urlbox.com/v1/render/sync` This, of course, works great in combination with [storing your renders in your own S3 bucket](https://urlbox.com/s3.md). --- # How to take screenshots with Zapier > Use Zapier to integrate screenshots with over 5,000 apps Source: https://urlbox.com/zapier Last updated: 2022-11-08 --- Our Zapier Integration is currently in beta with support for one trigger and two actions: ![zapier triggers and actions](/content/zapier/image1.png) - Trigger when a new screenshot is generated - Generate a screenshot from HTML - Generate a screenshot from a URL You're probably aware of just how much is possible with Zapier. They currently boast integrations with over 5,000 apps. So that's 5,000 apps that Urlbox can now integrate with. Ever wanted to check a website every hour, day, week or month? I've written a no-code guide to [automating website screenshots on a schedule](https://urlbox.com/automated-screenshots/automate-website-screenshots-schedule.md). In it I use Zapier's built in schedule trigger and then save the screenshot to Google Drive. You can also learn how to [generate screenshots from URLs in Airtable](https://urlbox.com/automated-screenshots/url-screenshots-airtable.md). --- # How to certify the content of a website with Urlbox > Need proof that a screenshot was taken at a given time and isn't altered? Our new `certify` option can do it. Source: https://urlbox.com/guides/certify-a-screenshot Last updated: 2025-04-15 --- We’re excited to introduce a new feature to our API: **Certified Screenshots**. This enhancement provides cryptographic proof that a screenshot was taken with a specific set of options at a given time, giving more authenticity and integrity to your renders. ## Why is this useful? Whether it's for regulatory archiving, brand monitoring, or digital forensics, this provides more authentic, trustworthy immutable web content. Here are some concrete use cases: - Regulatory Compliance – You may need to prove you displayed certain policies, disclosures, or terms at a specific time. - Preserving Online Content – Articles, social media posts, or public statements may be deleted or altered; a certified render ensures the truth remains captured. - Monitoring Competitor Activity – You can track and preserve changes to websites for compliance or legal disputes. ## How It Works When you make a render request, add `certify: true` to your options. In response, we return all the values we did before, plus: - A **timestamp** of when your screenshot was taken. - A **cryptographic hash** of the options, the rendered file, and the timestamp. - The **options** used in the hash (these may differ slightly from your inputted options). Storing these three allow you to verify the integrity of the screenshot at any time. Some of the options you provide may generate additional options automatically. This is why the hashed options might differ slightly from what you originally submitted. For example, we’ve recently updated Urlbox to use pre-signed URLs by default when storing renders in S3, to enhance security. When you include `use_s3=true`, we generate a `s3_presigned_url`—a derived option that becomes part of your final configuration. Rest assured, using S3 and certified renders is just as safe. Pre-signed URLs are intentionally ephemeral, meaning they expire after a short time. Even if someone gained access to your hash and could decode it, the pre-signed URL would likely have already expired, making it useless for uploading to your S3 bucket. **Note** - This approach works with all render formats—except for video formats and when using `html=<h1>Hello World!</h1>` instead of a `url=https://example.com`. It is not compatible with options that significantly alter the page’s structure or content, as that goes against the nature of this feature. Additionally, any options that might contain sensitive information are not compatible, to ensure privacy and security (except for `use_s3`). To confirm that a screenshot hasn't been altered, you can: 1. Take the `file`, the `timestamp`, and the returned `hashedOptions` and concatenate them together with a period between each one e.g. `"{file}.{timestamp}.{hashedOptions}"`. 2. Hash the concatenated string using the sha256 hashing algorithm. 3. Compare the hash to the one provided by our API response. 4. If the hashes match, the screenshot is verified as authentic and unaltered. ## Example You can make a request using your favoured method. Here's an example with Curl and Postman: ```Bash curl --location 'https://api.urlbox.com/v1/render/sync' \ --header 'Authorization: Bearer {{YOUR_URLBOX_SECRET_HERE}}' \ --header 'Content-Type: application/json' \ --data '{ "url": "https://theWebsiteYouWantToRender.com", "certify": true }' ``` The returned JSON should look familiar, with the addition of the `certifiedHash`, `timestamp` and `hashedOptions`: ```json { "renderUrl":"https://yourStorageLocation/yourRender.pdf", "size": 297573, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299, "timestamp": "Mon, 17 Mar 2025 10:30:25 GMT", "certifiedHash": "b64b8...", "hashedOptions": { "url": "https://theWebsiteYouWantToRender.com", "certify": true } } ``` To verify this, we recommend using a callable script for manual verification, to simplify the process for you. Feel free to write your own code which performs the steps above. The example below is based on a macOS/Linux environment with a shell script. Most hashing tools compatible with the sha256 algorithm should also work. #### Steps to verify: 1. Copy the below, save it as `verify.sh`. 2. Give it permission to run by executing `chmod +x verify.sh` in the command line. 3. Ensure you've got jq available for JSON formatting. 4. Take the `renderUrl` from the JSON response you received earlier, and save that render locally. 5. Run `./verify.sh /path/to/the/downloaded/file.pdf` in the command line. You'll be prompted for the JSON response from the API. Paste it with Ctrl+V and hit Ctrl+D twice to confirm. The response should show you the computed hash from the shell script, the certified hash from the JSON response, and whether they matched. If they match, then you have a certified screenshot! ```shell #!/bin/bash # Check that we passed in the downloaded file path if [[ $# -lt 1 ]]; then echo "Error: Missing local file path." echo "Usage: ./verify.sh <localFilePath>" exit 1 fi FILE_PATH="$1" # Ensure the file exists if [[ ! -f "$FILE_PATH" ]]; then echo "Error: File '$FILE_PATH' not found." exit 1 fi # Prompt to paste render response JSON echo "Paste JSON payload and press Ctrl+D twice when done:" JSON_INPUT=$(jq -nR '[inputs] | join("\n")' | jq -r '. | fromjson' 2>/dev/null) # Validate the JSON if [[ -z "$JSON_INPUT" || $(echo "$JSON_INPUT" | jq empty 2>&1) ]]; then echo "Error: Invalid JSON provided." exit 1 fi # Extract values from the JSON RENDER_TIMESTAMP=$(echo "$JSON_INPUT" | jq -r '.timestamp') CERTIFIED_HASH=$(echo "$JSON_INPUT" | jq -r '.certifiedHash') HASHED_OPTIONS_JSON=$(echo "$JSON_INPUT" | jq -cS '.hashedOptions') # Compute SHA-256 hash of the file BUFFER_HASH=$(shasum -a 256 "$FILE_PATH" | awk '{print $1}') echo echo "FILE: $FILE_PATH" echo "BUFFER_HASH: $BUFFER_HASH" echo "OPTIONS: $HASHED_OPTIONS_JSON" echo "TIMESTAMP: $RENDER_TIMESTAMP" echo # Compute the final hash to compare against the certified hash FINAL_HASH=$(echo -n "$BUFFER_HASH.$RENDER_TIMESTAMP.$HASHED_OPTIONS_JSON" | shasum -a 256 | awk '{print $1}') # Compare hashes MATCH_RESULT="false" if [[ "$FINAL_HASH" == "$CERTIFIED_HASH" ]]; then MATCH_RESULT="true" fi # Output results in JSON format jq -n \ --arg computedHash "$FINAL_HASH" \ --arg certifiedHash "$CERTIFIED_HASH" \ --arg match "$MATCH_RESULT" \ '{computedHash: $computedHash, certifiedHash: $certifiedHash, match: $match}' ``` Here's what an example Terminal Execution should look like: ```Shell ./verify.sh pdf.pdf Paste JSON payload and press Ctrl+D twice when done: { "renderUrl": "https://someRenderUrl/file.pdf", "size": 3966457, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299, "timestamp": "Mon, 17 Mar 2025 12:22:23 GMT", "certifiedHash": "8b707...", "hashedOptions": { "url": "https://theWebsiteYouWantToRender.com", "format": "pdf", "certify": true } } FILE: pdf.pdf BUFFER_HASH: 5780000... OPTIONS: {"certify":true,"format":"pdf","url":"https://theWebsiteYouWantToRender.com"} TIMESTAMP: Mon, 17 Mar 2025 12:22:23 GMT { "computedHash": "8b707...", "certifiedHash": "8b707...", "match": "true" } ``` ### Room to Improve We recognize that while it adds a layer of integrity verification, there are potential weaknesses. If you require stronger authenticity guarantees please reach out to us. We’re open to feedback and eager to evolve this feature to meet higher authentication and legal standards.

Happy rendering! --- # How to Build a Docker Image for a Website Screenshot Service > Need to run a website screenshot service? It's difficult to build a solution that runs reliably at scale, but Docker can help. Source: https://urlbox.com/guides/docker-website-screenshots Last updated: 2025-05-28 --- Docker lets you package all the complex components screenshot services depend on into a container that runs in any environment with Docker installed. But it's still hard to know which packages to include, or how to configure the container for maximum efficiency, security, and performance. In this article, we're going to walk you through implementing a Docker image that serves a website screenshot capture API. We'll create the API using [Puppeteer](https://pptr.dev), then write the [Dockerfile](https://docs.docker.com/reference/dockerfile) that builds the container image. We'll also highlight key best practices and potential gotchas along the way. Let's get started. ## Why Use Docker for a Website Screenshot Service? Website screenshot services programmatically capture content from webpages. They're typically built on web browser automation tools like [Puppeteer](https://pptr.dev). Puppeteer provides an API for controlling a Chrome or Firefox browser instance. You can use code to navigate to your target webpage, then save a screenshot capture. Puppeteer can be challenging to use in traditional server environments. To successfully capture screenshots, you need a functioning browser installation. In turn, this requires several dependencies not normally found in a typical headless environment, such as a display server, graphics packages, and fonts. Docker helps solve these problems. Packaging your code, Puppeteer, and browser dependencies as a Docker image lets you deploy your service with consistent results each time. Beyond reliable releases to production, Docker lets developers use tools like [Docker Compose](https://docs.docker.com/compose) to easily start a local instance of the service. They don't have to manually install Chrome, Puppeteer, and all the related dependencies on their machines. Similarly, using a Docker image to power your CI pipelines and testing processes guarantees that the dependency versions used for testing will exactly match those deployed to production. ## Tools You Need for a Dockerized Website Screenshot Service Creating a Dockerized website screenshot service requires more than just Docker. In this guide, we'll use the following tools: - **Browser Control Library (Puppeteer):** Puppeteer is a JavaScript library that provides an API for remotely controlling Chrome or Firefox. It interacts with the browser using [the DevTools Protocol](https://chromedevtools.github.io/devtools-protocol) or [WebDriver BiDi](https://pptr.dev/webdriver-bidi). Puppeteer defaults to using a headless browser instance, so the browser interface won't be displayed. This is ideal for server-side use in a screenshot service. If you prefer not to use Puppeteer, then [Selenium](https://www.selenium.dev) is an alternative option you could try. - **Programming Language (Node.js):** We're using [Node.js](https://nodejs.org) as our screenshot service's programming language and runtime environment. Node.js is a good choice because Puppeteer is a JavaScript library; using JavaScript for our application code makes it possible to directly call native Puppeteer APIs. However, Puppeteer bridge layers are available for many other popular programming languages. - **HTTP Server (Express):** You need an HTTP server and web framework if you want to expose your screenshot service as a web API for users to interact with. [Express](https://expressjs.com) is a popular framework for Node.js. - **Docker:** [Docker](https://www.docker.com) is a complete toolkit for building and running containers. It provides a convenient interface to lower level technologies such as the BuildKit image building system and Containerd container runtime. Docker creates [OCI-compliant](https://opencontainers.org) images that work with any container platform, whether Docker itself, an alternative like Podman, or orchestrators such as Kubernetes. With the tool list out of the way, let's begin building our Dockerized website screenshot service. ## Guide: Building a Docker Image for a Website Screenshot Service To get started building the service, first use npm to install the dependencies we'll be using: Puppeteer and Express. ```shell $ npm install puppeteer express ``` Now we’ll walk through creating the image. If you just want to see and run the code, then you can find all the project files [on GitHub](https://github.com/jamesheronwalker/urlbox-docker-puppeteer-screenshot-service). ### 1. Creating the API Code First, save the following code as `main.js` in your working directory. The code uses Express to serve an HTTP API on port 3000. The API provides a `/capture` endpoint that invokes Puppeteer to screenshot the webpage specified by the `url` query parameter. For example, sending a request to `localhost:3000/capture?url=https://www.google.com` will save a screenshot of Google's homepage. ```js title="main.js" const express = require("express"); const puppeteer = require("puppeteer"); const app = express(); const appPort = 3000; (async () => { const browser = await puppeteer.launch(); process.on("beforeExit", async () => { await browser.close(); }); app.get("/capture", async (req, res) => { const page = await browser.newPage(); await page.goto(req.query.url); await page.screenshot({path: `/captures/${Date.now()}.png`}); await page.close(); res.status(204).send(); `});` app.listen(appPort, () => { console.log(`Service is listening on port ${appPort}...`); }); })(); ``` There are a few important points to note in this code: - The browser instance is created as soon as the process starts, using `puppeteer.launch()`. This ensures the browser is ready to use when requests arrive, improving performance and enabling multiple connections to be served by the same instance. - The [`beforeExit` Node.js event](https://nodejs.org/api/process.html#event-beforeexit) is used to close the browser instance before the Node.js process terminates. This prevents redundant browser instances from accumulating. - The `/capture` endpoint uses Puppeteer's APIs to open a new page (tab) in the headless browser instance, navigate to the requested URL, and then save the screenshot into the `/captures` directory in the filesystem. We'll mount a [Docker volume](https://docs.docker.com/engine/storage/volumes) to this path in our container later on. Now you're ready to create the Docker image that'll run your service. ### 2. Creating the Dockerfile A [Dockerfile](https://docs.docker.com/reference/dockerfile) is a list of instructions that describe how to build a Docker image. It assembles the image's filesystem by copying files from your Docker host, running commands, and setting metadata. This article isn’t be an exhaustive guide to Dockerfile features, but you can find more detailed information [within Docker's documentation](https://docs.docker.com/reference/dockerfile). To continue, save the following Dockerfile as `Dockerfile` in your project's working directory—we'll explain each instruction below: ```dockerfile title="Dockerfile" FROM node:22 EXPOSE 3000 WORKDIR /app VOLUME /captures ENV PUPPETEER_SKIP_DOWNLOAD=true ENV PUPPETEER_EXECUTABLE_PATH=/usr/bin/chromium ENV XDG_CACHE_HOME=/tmp/.chromium ENV XDG_CONFIG_HOME=/tmp/.chromium RUN apt-get update &&\ apt-get install -y \ chromium \ libasound2 \ libatk-bridge2.0 \ libatk1.0 \ libcups2 \ libdbus-1-3 \ libgbm1 \ libjpeg62-turbo \ libnss3 \ libpng16-16 \ libxcomposite1 \ libxdamage1 \ libxkbcommon0 \ libxrandr2 COPY package.json . COPY package-lock.json . RUN npm ci COPY main.js . USER 1001 CMD ["main.js"] ``` Let's now walk through the Dockerfile line-by-line. #### `FROM node:22` This line sets the base image to the [official `node:22` image](https://hub.docker.com/_/node) available on Docker Hub. It includes the Node.js v22 LTS release and comes with npm already installed. #### `EXPOSE 3000` This metadata line indicates that the service in the container will listen on port 3000. This is the port we specified in our code. #### `WORKDIR /app` This line specifies the container working directory to be used for the following `COPY` instructions. #### `VOLUME /captures` The `/captures` path in the container is designated as a mount point so that generated screenshots will be automatically stored outside the container, on your Docker host. We'll discuss volume mounts in more detail below. #### `ENV PUPPETEER_SKIP_DOWNLOAD` and `ENV PUPPETEER_EXECUTABLE_PATH` Setting the `PUPPETEER_SKIP_DOWNLOAD` environment variable disables Puppeteer's built-in Chrome installation process that normally runs when you `npm install` or `npm ci`. Manually installing Chromium instead simplifies filesystem permission management and lets you manage your Chromium and Puppeteer versions independently. The `PUPPETEER_EXECUTABLE_PATH` environment variable tells Puppeteer where to find the Chromium binary when this method is used. #### `ENV XDG_CACHE_HOME` and `ENV XDG_CONFIG_HOME` Overriding these environment variables sets the directories where Chromium will store user data. These are changed from their defaults to avoid directory permission conflicts that can occur when running the process as a non-root user. #### `RUN apt-get update` and `apt-get install` This instruction uses Debian's apt package manager to install Chromium and its key dependencies. The list of libraries is the minimum required to successfully launch Chromium and generate screenshots with Puppeteer. It includes key X11 display libraries, the D-Bus message bus system, and JPEG and PNG handling libraries. #### `COPY package.json` and `npm ci` This step copies your npm package files from your working directory, then uses `npm ci` to install your dependencies in the container. The step comes after the apt dependencies are installed because the npm dependencies are smaller and faster to download. This order ensures Docker's layer cache is used efficiently. #### Copying Source Code The remaining steps copy the app's source code, specify a non-root user for the container to run as (we'll discuss this in more detail below), and instruct Docker to run `main.js` as the container's foreground process. ### 3. Creating a Docker Compose File This step is optional, but it makes it easier to build and run your container image consistently. Save the following file as `docker-compose.yml`: ```yaml title="docker-compose.yml" services: screenshotter: image: urlbox-docker-screenshot-demo:latest build: context: . dockerfile: Dockerfile ports: - 3000:3000 cap_add: - SYS_ADMIN volumes: - ./captures:/captures ``` This Docker Compose file defines our image's name and specifies it should be built from `Dockerfile`. The `ports` section sets up a port binding from port 3000 on your host to the container's port 3000, allowing you to access the Express API on `localhost:3000`. The `cap_add` section grants the `SYS_ADMIN` capability to the container. This allows Chromium to successfully run as a non-root user with sandboxing enabled (we'll explain this in more detail below). Under the `volumes` section, a bind mount is configured between the `captures` folder in your working directory and `/captures` in the container. It enables the screenshots saved by the API to be viewed on your host under `captures`. Because the Chromium process in the container runs as the non-root user `1001`, you must set appropriate permissions on the directory that allow other users to write to it. ```shell $ mkdir -p captures $ chmod 777 captures ``` ### 4. Build the Container Image Now we're ready to use Docker Compose to build and tag the container image: ```shell $ docker compose build ``` The build output will be displayed in your terminal window. Wait until you see that the image has been built successfully before continuing. The build may take several minutes to complete while the Chromium and Puppeteer dependencies are installed. ### 5. Start a Container and Test Your Screenshot Service It's now time to test the service! Use `docker compose up -d` to start your service as a background process on your Docker host. This will use the config in your `docker-compose.yml` file to create a container, assign the `SYS_ADMIN` capability, bind mount the `captures` directory, and set up a port binding on port 3000. ```text $ docker compose up -d [+] Running 2/2 ✔ Network url001_default Created 0.0s ✔ Container url001-screenshotter-1 Started 0.3s ``` Once the container has started, try using curl to request `localhost:3000/capture?url=https://www.google.com`. You should see that the screenshot is saved to your `captures` directory after a few seconds. ```shell curl 'localhost:3000/capture?url=https://www.google.com' ``` We've now successfully created a Docker container for this simple screenshot service! You can proceed to manage the container using standard Docker or Docker Compose commands, such as `docker compose logs` to check the container's output: ```text $ docker compose logs screenshotter-1 | Service is listening on port 3000... ``` ## Best Practices for Website Screenshot Service Docker Containers The Docker image we created above is an effective starting point to containerize Puppeteer-based screenshot services. However, you should also note the following best practices to improve your service's performance, security, and scalability. ### Run the Container as a Non-Root User Docker defaults to running containers as the `root` user. If an attacker successfully compromises the process running in the container, they may also be able to gain control of your Docker host. This is particularly important for Puppeteer applications because browsers require many capabilities and have a large attack surface. Use the Dockerfile `USER` instruction—as shown in the image we created above—to mitigate this risk by ensuring your container processes run as a non-root user. ### Keep Chrome's Linux Sandbox Enabled It's crucial to keep Chrome's sandboxing protections enabled when you're running Puppeteer in a Docker container. Chrome uses Linux sandboxes to isolate web content, preventing malicious JavaScript from breaking out of the process. The sandbox requires your containers to run with the `SYS_ADMIN` capability enabled, as shown above. Many Docker and Puppeteer tutorials advise using the `--no-sandbox` Puppeteer launch option. When this option is used, the container doesn't need extra capabilities and Chrome will successfully run as Docker's default `root` user. However, the option completely disables sandboxing protections so it shouldn't be used in production. It's safer to use a non-root container user, assign the `SYS_ADMIN` container capability, and keep sandboxing enabled. ### Ensure Efficient Docker Image Layer Caching Running the build for a Puppeteer Docker image can take several minutes. There's many large dependencies to download and install. To reduce waiting times, you should optimize the order of instructions in your Dockerfile to improve layer caching efficiency. Docker creates a new layer for each instruction in your Dockerfile; those layers will be reused on the next build if none of the layers above them have changed. Content that infrequently produces changes—such as installing `apt` and `npm` dependencies—should therefore come before operations like copying in your source code. In the following example, the copy operation will invalidate the layer cache each time your source code changes: ```dockerfile title="Dockerfile" COPY package.json . COPY src/ . RUN npm ci ``` This causes `npm ci` to run on every build, even though only your source code might have changed. Restructuring the Dockerfile as follows produces a more efficient build sequence: ```dockerfile title="Dockerfile" COPY package.json . RUN npm ci COPY src/ . ``` Now Docker only has to run `npm ci` if your `package.json` file has changed. ### Optimize Image Size Using Multi-Stage Builds Docker images for Puppeteer-based screenshot services can quickly grow large. The image created in this article is roughly 1.9 GB, for instance. The Chromium binary and dependencies carry unavoidable weight, but taking advantage of Docker's [multi-stage build features](https://docs.docker.com/build/building/multi-stage) can help optimize your final output size. Running code compilation processes in a separate stage lets you discard any development tools that don't need to be retained in the final image, for example: ```dockerfile title="Dockerfile" FROM node:22 AS build COPY src/ . COPY *.json . RUN npm ci RUN npm build --output-dir /build/app FROM node:22 # (install Puppeteer + dependencies here) COPY --from=build /build/app . CMD ["app"] ``` This image will only include the Puppeteer dependencies and the compiled `/build/app` output. The dependencies downloaded by the `build` stage’s `npm ci` command won’t be present in the final image. ### Include Common Font Packages so Screenshots Render Correctly The screenshots produced by a Dockerized Puppeteer instance may show incorrect fonts compared with what you see when you visit the website. Many websites rely on common system fonts, but these won't automatically be present inside your container. Adding key font packages like `fonts-freefont-ttf` and `ttf-mscorefonts-installer` to your Dockerfile will ensure common fonts or close alternatives are available. ```dockerfile RUN apt-get update && apt-get install -y fonts-freefont-ttf ``` ### Run Puppeteer as a Separate Microservice Alongside Your App Puppeteer and the code that controls it is best operated as a standalone microservice alongside your app. This ensures you can scale the two components independently to improve high availability and performance. Our demo image is a good example of what a standalone Puppeteer microservice could look like. It provides a simple API that your other microservices can call to capture a screenshot. Decoupling Puppeteer in this way also makes it easier to change between screenshot capture services if you need to. For instance, you could replace your custom Puppeteer solution with [Urlbox’s](https://urlbox.com) ready-to-use capture API by updating the endpoint that your application code calls. ## Summary Website screenshot services provide a convenient interface to programmatically capture webpage images. They can help you archive user-generated content, scrape information, or analyze a page's visual changes over time. Browser automation tools like Puppeteer provide the technical foundation for building a website screenshot service, but their complex dependencies mean it's often challenging to configure new environments. Creating a Docker image lets you operate your service reliably, whether in development, CI/CD, or production, without risking missing dependencies or conflicting versions. You can also use your Docker image to scale your service by deploying multiple replicas using a container orchestrator like Kubernetes. The screenshot service and container image we've created in this guide is still a simplified example. A real service will usually need many more features to ensure quality results, such as: - Full page screenshot support - Proxying to circumvent regional content blocks - Evasions to deal with captchas, scroll jacking, infinite scroll, and cookie banners - GPU access to ensure WebGL and WebGPU sites render correctly - Support for other output formats such as PDF, scrolling video, or direct S3 image uploads (typically requiring additional dependencies) This list is just a starting point of what you might want to include. If it all seems too complicated—and we think it is—then check out [Urlbox](https://urlbox.com) instead. Urlbox is a simple screenshot API that you can call from your code. We make it easy to generate high-quality website captures without having to manually configure or operate Puppeteer. Urlbox supports all the capabilities listed above and many more, ensuring your captures always render as expected.

Source: https://urlbox.com/golang-website-screenshots Last updated: 2025-03-21 --- As a Go developer, the need for programmatically taking screenshots of websites may arise in different scenarios. It may be part of an important feature of an application you're building, such as a website monitor, or even for documentation or compliance purposes. Unfortunately, there are more use cases than there are complete Go-based solutions that adequately tackle this functionality without having to resort to other languages, such as JavaScript. In this article, you will learn about the options you have as a Go developer and some of the flaws they present, as well as how you can fix all that with Urlbox, a fast, accurate, and reliable [screenshot API](https://urlbox.com/screenshot-api.md). You can find all the code used in this article in this [GitHub repo](https://github.com/rexfordnyrk/golang-web-screenshot-demos). ## gowitness [gowitness](https://github.com/sensepost/gowitness) is an easy-to-use command-line program that is used to take screenshots of web pages. It is built with Golang, and is available on Linux and Mac, with some support for Windows. It uses headless Chrome to navigate web pages and take screenshots. It also captures the metadata of the target sites. ### Features gowitness offers a number of useful features. The following is a non-exhaustive list of features it offers: - It is a command-line tool with a single, easily installed binary. - Taking a screenshot of a single URL from the command-line without writing code. - Specifying dimensions/resolution for a screenshot. - Running a web service that takes screenshots. - Batch taking screenshot URLs sourced from a file. This allows you to make a list of URLs, and then have them all captured in a single run. ### Using gowitness to Capture Screenshots In order to start using it, you need to install gowitness directly using the `go install` command: ```bash $ go install github.com/sensepost/gowitness@latest ``` With gowitness installed, you can start exploring its functionalities by taking a screenshot of a single URL using the command below: ```bash $ gowitness single https://www.itsfoss.com/install-docker-fedora ``` This will create a screenshot with the name of the URL and place it into a `screenshot` folder in the directory from which the command is executed. The screenshot captured is seen below. ![gowitness single screenshot](/content/golang-website-screenshots/6ktxnGp.png) Screenshots taken are 1440 x 900 (width x height) by default, but you can also take a full-page screenshot by including the `--fullpage` flag with the command, or by including the required dimensions, such as. `-X 390 -Y 844`, which is good for simulating mobile views. You can take one of each by running the following commands: ```bash # creating a full page screenshot $ gowitness --fullpage single https://www.itsfoss.com/install-docker-fedora # creating a mobile view screenshot with width 390 and a height of 844 $ gowitness -X 390 -Y 844 single https://www.itsfoss.com/install-docker-fedora ``` ![gowitness full-page screenshot](/content/golang-website-screenshots/gc9WA2d.png) ![gowitness 390 x 844 mobile view screenshot](/content/golang-website-screenshots/NowEXIR.png) You can make HTTP calls to grab screenshots directly from your application's codebase by running the executable as a service by using the command `gowitness server`, as seen below. The screenshot has the same size parameters as before, and can be modified the same way. ```bash $ gowitness --fullpage server 16 May 2022 03:23:40 INF server listening address=localhost:7171 ``` This response tells you that the server is running and accessible locally via the URL localhost:7171. Now create the Go program to capture the screenshots from the gowitness web service. Create a new file, `gowitness_api.go,` add and save the following code to it: ```go package main import ( "fmt" "io/ioutil" "log" "net/http" "net/url" "time" ) func main() { //calling the function to fetch the screenshot of the URL we want getImage("www.itsfoss.com/install-docker-fedora") } func getImage(site string){ //concatenating the url string to make the request. screenShotService := fmt.Sprintf("http://localhost:7171?url=%s%s","https://", url.QueryEscape(site)) log.Printf("................making request for screenshot using %s", screenShotService) //making the get request to the gowitness screenshot service resp, err := http.Get(screenShotService) //checking if there are any errors and logging them if err != nil { log.Fatalln(err) } //We read the response body (the image) on the line below. body, err := ioutil.ReadAll(resp.Body) if err != nil { log.Fatalln(err) } // You have to manually close the body //but defer closing till the method is done executing and is about to exit defer resp.Body.Close() //naming file using provided URL without "/"s and current unix datetime filename := fmt.Sprintf("%s-%d.png",strings.Replace(site,"/","-",-1), time.Now().UTC().Unix()) // You can now save it to disk... errs := ioutil.WriteFile(filename, body, 0666) if errs != nil { log.Fatalln(errs.Error()) } log.Printf("..............saved screenshot to file %s", filename) } ``` The program makes an HTTP request to the gowitness service with the URL you want to capture as a query parameter in the format `?url=domain.com`. This captures a screenshot, which is saved as a PNG image file with the URL captured and the Unix time of capture as its name. As before, it's saved to the directory from which the program was run. You can run the program by using the `go run` command in your terminal, as seen below with its output: ```bash $ go run gowitness_api.go 2022/05/16 13:51:11 ................making request for screenshot using http://localhost:7171?url=https://www.itsfoss.com/install-docker-fedora 2022/05/16 13:54:50 ..............saved screenshot to file www.itsfoss.com-install-docker-fedora-1653054890.png ``` From the logs above, you can see that this process took almost four minutes. This is the screenshot from the program: ![gowitness server full-page screencapture](/content/golang-website-screenshots/x5CKE0r.png) ### Cons of Using Gowitness While gowitness can seem like an appealing solution, its shortcomings become apparent quickly. Screenshots are sometimes taken before the page has fully loaded, resulting in blank spaces where images are expected to be. In such situations, gowitness provides the command line flag `–delay <number_of_seconds>` to specify a wait period for the page to load as much as possible before taking the screenshot. Additionally, screenshots of pages with ads include the ads, only some of which have fully loaded, resulting in not just ads, but also odd gaps and places where out-of-position ads are overlapping the content. gowitness can't be integrated with an existing codebase unless you choose to run it as a service and make HTTP calls to the service to take screenshots, forcing you to run and maintain a service. The web service can take several minutes to finish, and hangs sometimes, dropping the HTTP requests. Additionally, the web service isn't secure, and doesn't allow you to specify the resolution. ## chromedp Built from the ground up in Go with no third-party dependencies, [chromedp](https://github.com/chromedp/chromedp) is a high-level client for the [Chrome DevTools Protocol](https://chromedevtools.github.io/devtools-protocol). It enables developers to programmatically interact or automate browser-based actions with web pages and applications. Web scraping, application unit testing, and web page profiling are some of the main use cases for chromedp. This tool allows you to use code to do almost anything you would do in the browser. ### Features chromedp provides many features. The ones most relevant to this article are as follows: - Taking a standard screenshot of a web page with the dimensions of your choice. - Taking a full-page screenshot of a web page. - Taking a screenshot of a specific element on a web page. - Exporting a web page to PDF. - Performing various navigation and interactive activities, such as clicking a button, programmatically. ### Using chromedp to Capture Screenshots chromedp version 0.8.1, the current version as of this writing, works with a minimum of Go version 1.7. You may have to use version 0.8.0 of chromedp if you are running an older version of Go. You can get the package by running the command below: ```bash $ go get -u github.com/chromedp/chromedp@v0.8.0 ``` Once you have the chromedp package and dependencies, it's time to take some screenshots with it. First, you'll take a standard screenshot with a specified resolution of 1440 by 900, then you'll take a full-page screenshot of the same page. To get started with the code, create a new file called chromedp.go, then add the following code and save the file: ```go package main import ( "context" "fmt" "github.com/chromedp/chromedp" "io/ioutil" "log" "strings" "time" ) func main() { getChromedpScreenShot("www.itsfoss.com/install-docker-fedora",100) } func getChromedpScreenShot(site string, quality int) { //forming url to be captured screenShotUrl := fmt.Sprintf("https://%s/", site) //byte slice to hold captured image in bytes var buf []byte //setting image file extension to png but var ext string = "png" //if image quality is less than 100 file extension is jpeg if quality < 100 { ext = "jpeg" } log.Printf("................making request for screenshot using %s", screenShotUrl) //setting options for headless chrome to execute with var options []chromedp.ExecAllocatorOption options = append(options, chromedp.WindowSize(1400, 900)) options = append(options, chromedp.DefaultExecAllocatorOptions[:]...) //setup context with options actx, acancel := chromedp.NewExecAllocator(context.Background(), options...) defer acancel() // create context ctx, cancel := chromedp.NewContext( actx, ) defer cancel() //configuring a set of tasks to be run tasks:= chromedp.Tasks{ //loads page of the URL chromedp.Navigate(screenShotUrl), //waits for 5 secs chromedp.Sleep(5*time.Second), //Captures Screenshot with current window size chromedp.CaptureScreenshot(&buf), //captures full-page screenshot (uncomment to take fullpage screenshot) //chromedp.FullScreenshot(&buf,quality), } // running the tasks configured earlier and logging any errors if err := chromedp.Run(ctx, tasks); err != nil { log.Fatal(err) } //naming file using provided URL without "/"s and current unix datetime filename := fmt.Sprintf("%s-%d-standard.%s",strings.Replace(site,"/","-",-1), time.Now().UTC().Unix(), ext) //write byte slice data of standard screenshot to file if err := ioutil.WriteFile(filename, buf, 0644); err != nil { log.Fatal(err) } //log completion and file name to log.Printf("..............saved screenshot to file %s", filename) } ``` The code above first sets up various options by which chromedp is going to navigate our URL. For instance we are setting the window size to a width of 1400 and a height of 900. Then a context is created using the options. Next, a set of tasks for chromedp to run are configured: - Navigate to the target URL. - Wait five seconds to allow content to load or finish animating. - Capture a screenshot. You can now run the code by using the `go run` command, and it should return output similar to this: ```bash $ go run chromedp.go 2022/05/19 19:17:13 ................making request for screenshot using https://www.itsfoss.com/install-docker-fedora/ 2022/05/19 19:17:29 ..............saved screenshot to file www.itsfoss.com/install-docker-fedora-1652987849.png ``` To capture a full-page screenshot, comment out `chromedp.CaptureScreenshot(&buf)`, and uncomment `//chromedp.FullScreenshot(&buf,quality),`. Now run the code, and you'll see output similar to this: ```bash $ go run chromedp.go 2022/05/19 19:20:44 ................making request for screenshot using https://www.itsfoss.com/install-docker-fedora/ 2022/05/19 19:22:21 ..............saved screenshot to file www.itsfoss.com-install-docker-fedora-1652988141.png ``` These are the resultant screenshots: ![chromedp standard screenshot](/content/golang-website-screenshots/Kg3NFOL.png) ![chromedp full-page screenshot](/content/golang-website-screenshots/jUXCQW1.png) ### Cons of Using chromedp The full-page screenshot wasn't taken of a fully loaded page, which is evident from the blank spaces where there should be images. Additionally, since this solution doesn't do anything to minimize or eliminate ads, all the ads that have loaded are captured, as well, and the page ends up with a lot of blank space, and some out-of-position ads running through the content. You can also see from the output above that the full-page screenshot took a long time to complete, almost two minutes. ## Urlbox [Urlbox](https://urlbox.com/.md) is a screenshot API service that empowers businesses, developers and users to reliably capture clean screenshots of websites. ### Features Urlbox offers an assortment of unique features, some of which are highlighted below. - Supports saving or exporting to multiple, including PNG, JPEG, WebP, PDF, and SVG formats. - You can specify the dimensions or resolution for screenshots, including full-page captures. - Allows you to block ads, hide cookie banners, and dismiss pop-ups before taking a screenshot. You can even bypass CAPTCHAs. - Enables you to hide elements using selectors, and prevent other URLs from loading on the page. - Taking 'retina', or high-definition, screenshots. - Exporting to PDF has the flexibility of page sizes, and supports setting options for margins, scaling, orientation, background, and many others. ### Using Urlbox To Capture Screenshots Urlbox doesn't offer a Golang package, but they offer a straightforward, [well-documented API](https://urlbox.com/docs.md) that can be used to make requests to their APIs using the HTTP client from the Go standard library. To get started using Urlbox, you'll need to register for a trial account. That provides you with API key and secret, which you'll need to use their APIs. Then, you can create a simple Go program to capture screenshots of websites or web pages. Create a new file called `urlbox.go`, and paste in the following code, then save the file: ```go package main import ( "fmt" "io/ioutil" "log" "net/http" "net/url" "strings" "time" ) func main() { getUrlBoxImage("www.itsfoss.com/install-docker-fedora", "YOUR-API-KEY") } func getUrlBoxImage(site string, apiKey string){ //concatenating the api key and document format to make the request screenShotService := fmt.Sprintf("https://api.urlbox.com/v1/%s/png?", apiKey) //creating a map of key-value pairs of Urlbox API options params := url.Values{ "url": {site}, "width": {"1400"}, "height": {"900"}, } //Configuring the request with the method, URL, and body req, err := http.NewRequest("GET", screenShotService, nil) if err != nil { log.Fatalln(err) } //encode values into URL encoded form/query parameters req.URL.RawQuery = params.Encode() //printing out to console the entire request url with params. You can comment this out fmt.Println(req.URL.String()) //Create a default HTTP client to make the request client := &http.Client{} //making the get request to the Urlbox screenshot API resp, err := client.Do(req) if err != nil { log.Fatalln(err) } //defer closing of body till the method is done executing and about it exit defer resp.Body.Close() //We read the response body (the image) on the line below. body, err := ioutil.ReadAll(resp.Body) if err != nil { log.Fatalln(err) } //naming file using provided URL without "/"s and current unix datetime filename := fmt.Sprintf("%s-%d.png",strings.Replace(site,"/","-",-1), time.Now().UTC().Unix()) // You can now save it to disk... errs := ioutil.WriteFile(filename, body, 0666) if errs != nil { log.Fatalln(errs.Error()) } log.Printf("..............saved screenshot to file %s", filename) } ``` As you can see, the code above is very simple. - You create a function called `getUrlboxImage`. This function accepts two strings as arguments: the target URL, and the API key to authenticate the request. - Next, you initialize map values of the various options to define how the screenshots should look. In this example, only options for height and width are specified. A detailed reference to the options and what they do can be found [in the documentation](https://urlbox.com/docs/options.md). - An HTTP GET request with the URL and encoded query parameters is configured and made to the API endpoint. This request is checked for errors, and any errors are logged. - Finally, the body of the response, which is expected to be a PNG file as specified in the request URL, is read and written to a file using the URL and the current timestamp as the file name. Additionally, a log message is created with the filename. Run the program: ```bash $ go run urlbox.go ``` This is the screenshot obtained: ![Urlbox 1400x900 screenshot](/content/golang-website-screenshots/AdQAfxP.png) To see what Urlbox brings to the table, you'll take two screenshots: one with the ads, and one in which the ads and other intrusive elements have been blocked. First, modify the map of options as below to capture a full-page screenshot with ads. Run the program to take your first capture. ```go //creating a map of key-value pairs of Urlbox API options for full page with ads params := url.Values{ "url": {site}, "width": {"1440"}, "full_page": {"true"}, ///for full page screenshot } ``` Now, it's time to apply some of Urlbox's magic to the screenshot. Modify the options as shown and commented in the code block below, and run the program to capture the full page without ads or banners. ```go //creating a map of key-value pairs of Urlbox API options for full page without adds params := url.Values{ "url": {site}, "width": {"1400"}, "full_page": {"true"}, //for full page screenshot "block_ads": {"true"}, //remove ads from page "hide_cookie_banners": {"true"}, //remove cookie banners if any "click_accept": {"true"}, //click accept buttons to dismiss pop-ups } ``` Below are the two images captured. You can see how easy it is to get a great screenshot without any hassle. Unlike the other screenshots you've taken in this tutorial, all images show fully in both versions, and the content is where it should be. It's also significantly faster than the other options. ![Full-page Urlbox screenshot with ads](/content/golang-website-screenshots/Vh76tB1.png) ![Full-page Urlbox screenshot with the ads removed](/content/golang-website-screenshots/XhUvRXF.png) ## Conclusion As a Go developer, you don't have many options to automate website screenshots. As you've seen in this article, common options have some serious drawbacks, including slow response times and cluttered, half-loaded screenshots with out-of-place ads obscuring the content. This article also introduced you to [Urlbox](https://urlbox.com/.md), a better way to take screenshots. It produces perfect, ad-free, visually clear screenshots, and it doesn't require that you build and maintain your own screenshot service. --- # How to Screenshot Facebook > A working configuration for screenshotting Facebook programmatically using the Urlbox Screenshot API.

Source: https://urlbox.com/how-to-take-website-screenshots-elixir Last updated: 2022-06-09 --- Web scraping is a handy tool for gathering information from a website that most developers will use at some point in their life. Web scrapers usually load, parse, and extract useful data from a website's HTML code. However, there are times when this isn't enough, and you might need to take screenshots of a website. For example: - **Debugging:** As part of a web crawler or some version of end-to-end testing, you might need to take screenshots of a website to help debug a problem and understand what is being rendered. - **Automating:** Automate the routine work of reviewing dashboards or sites for changes and distributing that to other channels like Slack. - **Sharing:** Sharing data behind logins with users that don't have access. - **Legal or compliance documentation:** Taking screenshots of the contents of a URL as a way of documenting content to provide evidence to legal teams or auditors. - **Tracking changes:** Tracking changes to a website and sending out notifications to users. Elixir is a functional, concurrent, general-purpose programming language mostly used to build scalable and maintainable web applications. In this article, you'll learn several different ways of taking screenshots programmatically with the Elixir programming language, as well as the limitations of each method. You'll also get a better understanding of what is happening behind the scenes when those screenshots are generated. ## Prerequisites For this article, you'll be using [Elixir](https://elixir-lang.org/) and [Node.js](https://nodejs.org/en/) for one of the example dependencies. Before we get started, make sure you have the following installed: - Elixir 11.x or greater - NPM 8.x or greater - Node.js 16.x or greater Please note that it's highly recommended that you use a tool like [asdf](https://www.pluralsight.com/guides/installing-elixir-erlang-with-asdf) to install these dependencies. ## Taking Screenshots Programmatically According to [Stack Overflow](https://insights.stackoverflow.com/survey/2019#most-loved-dreaded-and-wanted), Elixir has quickly become one of the most-loved languages, and not without reason—it combines powerful language features with Ruby-like syntax. In the context of web scraping, Elixir is a great language to use because of its concurrency and functional features. However, one important thing to keep in mind is that in order to take screenshots of a website, you need to be able to render the website just like any browser would. The following examples will showcase different libraries and tools that can be used, and the limitations of each. ### Using PuppeteerImg Our first example will be using [PuppeteerImg](https://github.com/RobotsAndPencils/ex-puppeteer-img), a library that allows you to take screenshots of websites, to take the screenshots. PuppeteerImg is a wrapper of a Node.js package called [puppeteer-img](https://www.npmjs.com/package/puppeteer-img), which is a simple library used to generate screenshots of websites. The code for this example can be found in [this GitHub repo](https://github.com/amacgregor/puppeteer_example). #### Setting Up the Project Start by creating a new project in your Elixir workspace: ```elixir mix new puppeteer_example --sup ``` On success, you'll see the following output: ```bash * creating README.md * creating .formatter.exs * creating .gitignore * creating mix.exs * creating lib * creating lib/puppeteer_example.ex * creating lib/puppeteer_example/application.ex * creating test * creating test/test_helper.exs * creating test/puppeteer_example_test.exs Your Mix project was created successfully. You can use "mix" to compile it, test it, and more: cd puppeteer_example mix test Run "mix help" for more commands. ``` #### Dependencies and Configuration Next, you'll set up the dependencies and configuration for your project. Go into the `puppeteer_example` directory, and add the following to the `mix.exs` file: ```elixir defp deps do [ {:puppeteer_img, "~> 0.1.3"} ] end ``` Proceed to install the dependencies by running the following command: ```elixir mix deps.get ``` You'll also need to install `puppeteer-img` globally, using the following command: ```bash npm i puppeteer-img -g ``` #### Taking Screenshots The next step is to add the main function to your project. Go into the `puppeteer_example` directory, and add the following to the `lib/puppeteer_example.ex` file: ```elixir defmodule PuppeteerExample do def take_screenshot(url, filename) do options = [ type: "jpeg", path: "./" <> filename ] case PuppeteerImg.generate_image(url, options) do {:ok, path} -> IO.puts(path) # where "path" == final path where generated image is stored. {:error, error} -> IO.puts(error) # where "error" == some error message. end end end ``` Open up the interactive REPL by running `iex -S mix`, then run the following command to take a screenshot of the website: ```elixir PuppeteerExample.take_screenshot("http://techcrunch.com", "techcrunch.jpeg") ``` If everything worked correctly, you should see the following output: ```bash ./techcrunch.jpeg :ok ``` And a new screenshot should be generated in the `puppeteer_example` directory. ![Screenshot with Puppeteer](/content/how-to-take-website-screenshots-elixir/L7pxlUh.jpeg) #### Drawbacks and Things to Consider With very little code, you were able to create an Elixir application that can take screenshots of a website. However, there are a few things to consider with this approach: - **Manual Configuration:** We need to configure the library to take screenshots of a website manually. - **Relies on Node.js libraries:** PuppeteerImg is a wrapper of a Node.js package, and as such, it requires that Node.js and Puppeteer be installed on the system. This makes deployment and maintenance of the application much more complex, as it requires that you keep track of an additional technology stack. **Lack of Automation:** PuppeteerImg will work well for instances where you don't need to automate any user action or login to a website, but won't be enough for more complex scenarios. **Poor rendering**: This approach will also fail to handle and dismiss visual distractions such as popups and cookie banners, and can potentially falter when rendering JavaScript heavy pages. ### Using Hound For more complex scenarios, you can use [Hound](https://github.com/HashNuke/hound) to take screenshots of a website. Hound is an Elixir library meant for browser automation and writing integration tests. Behind the scenes, Hound supports multiple headless browsers. Notable features include: - Can support multiple browsers simultaneously. - Support for Selenium WebDriver, ChromeDriver, and PhantomJS. - Support for JavaScript-heavy applications, and retry logic. - Compliant with the [WebDriver Wire Protocol](https://www.w3.org/TR/webdriver/). The code for this example can be found in [this GitHub repo](https://github.com/amacgregor/hound_example). #### Setting Up the Project Start by creating a new project in your Elixir workspace: ```elixir mix new hound_example --sup ``` On success, you will see the following output: ```bash * creating README.md * creating .formatter.exs * creating .gitignore * creating mix.exs * creating lib * creating lib/hound_example.ex * creating lib/hound_example/application.ex * creating test * creating test/test_helper.exs * creating test/hound_example_test.exs Your Mix project was created successfully. You can use "mix" to compile it, test it, and more: cd hound_example mix test Run "mix help" for more commands. ``` #### Dependencies and Configuration Start by adding the dependencies to the `mix.exs` file: ```elixir defp deps do [ {:hound, "~> 1.0"} ] end ``` Proceed to install the dependencies by running the following command: ```elixir mix deps.get ``` Unlike PuppeteerImg, which took care of setting up and launching a headless browser behind the scenes, Hound requires that you do this manually. By default, Hound will use PhantomJS, but you can avoid using another Node.js package by instead using the [Selenium WebDriver](https://www.seleniumhq.org/projects/webdriver/). Start by [downloading](https://selenium-release.storage.googleapis.com/3.9/selenium-server-standalone-3.9.1.jar) the [Selenium standalone server](https://www.selenium.dev/). Start the server with: ```bash java -jar selenium-server-standalone-3.9.1.jar ``` Alternatively, if you are using macOS with Homebrew, you can install the Selenium standalone server with: ```bash brew install selenium-server-standalone selenium-server standalone ``` In either case, you can confirm that the server is running correctly by visiting localhost:4444/wd/hub to see if you can see the following output: ![Selenium standalone server installed](/content/how-to-take-website-screenshots-elixir/5JhG1Ft.png) Finally, you'll need to configure Hound to use the Selenium server. Go into the `hound_example` directory, and create a new configuration file called `config/config.exs`: ```bash mkdir config touch config/config.exs ``` Add the following to the `config/config.exs` file: ```elixir import Config config :hound, driver: "selenium", port: 4444 ``` #### Taking Screenshots With your initial configuration complete, you can now work on the main logic. Go into the `hound_example` directory, and add the following to the `lib/hound_example.ex` file: ```elixir defmodule HoundExample do require Logger use Hound.Helpers def take_screenshot(url, filename) do Logger.info "Taking screenshot of #{url} and saving to #{filename}" Hound.start_session navigate_to url take_screenshot("./#{filename}") Hound.end_session Logger.info "Screenshot saved to #{filename}" {:ok, filename} end end ``` Open up the interactive REPL by running `iex -S mix`, then run the following command to take a screenshot of the website: ```elixir HoundExample.take_screenshot("https://techcrunch.com/", "techcrunch_hound.jpeg") ``` If things worked correctly, you should see the following output: ```bash Interactive Elixir (1.13.3) - press Ctrl+C to exit (type h() ENTER for help) iex(1)> HoundExample.take_screenshot("https://techcrunch.com/", "techcrunch_hound.jpeg") 12:40:00.790 [info] Taking screenshot of https://techcrunch.com/ and saving to amgr_hound.jpeg 12:40:05.423 [info] Screenshot saved to techcrunch_hound.jpeg {:ok, "techcrunch_hound.jpeg"} ``` And should have a screenshot generated in the `hound_example` directory that looks like this: ![Screenshot with Hound](/content/how-to-take-website-screenshots-elixir/XgVhRGa.png) You might have noticed that unlike the previous example, where the screenshot happened without opening a new browser window, in this instance, Hound will open a new browser window for you. The Selenium WebDriver defaults to this when taking a screenshot, although headless mode can be achieved by further tweaking the configuration. Further configuration options can be found in the [Hound documentation](https://github.com/HashNuke/hound/blob/master/notes/configuring-hound.md). #### Drawbacks and Things to Consider One of the main advantages of using Hound as opposed to PuppeteerImg is that everything happens as part of a session, and you can interact with the page programmatically. This means it can support more complex scenarios, such as: - Logging in to a website and taking screenshots of a dashboard. - Interacting with modals and dialogs. - Following the navigation and taking screenshots of the next page. However, there are still some drawbacks to this approach: - Hound is meant to be used for automated testing, so special care must be taken to ensure that errors when trying to access a page are handled gracefully. - The `take_screenshot` method is not configurable, and lacks useful options like quality and full-page support. - An application following this approach still depends on a third-party package, though with Selenium, the actual server could be deployed separately from the application. ### Using Urlbox For the final example, you'll leverage [Urlbox](), a website screenshot service with a simple API. Specifically, this tutorial will use [ExURLBox](https://github.com/amineo/ex_urlbox) a light wrapper around the [Urlbox API](https://urlbox.com/docs.md). The code used in this tutorial can be found in this [GitHub repo](https://github.com/amacgregor/urlbox_example). #### Setting Up the Project Start by creating a new project in your Elixir workspace: ```elixir mix new urlbox_example --sup ``` On success, you will see the following output: ```bash * creating README.md * creating .formatter.exs * creating .gitignore * creating mix.exs * creating lib * creating lib/urlbox_example.ex * creating lib/urlbox_example/application.ex * creating test * creating test/test_helper.exs * creating test/urlbox_example_test.exs Your Mix project was created successfully. You can use "mix" to compile it, test it, and more: cd urlbox_example mix test Run "mix help" for more commands. ``` #### Dependencies and Configuration Start by adding the dependencies to the `mix.exs` file: ```elixir defp deps do [ {:ex_urlbox, "~> 0.2.0"} ] end ``` Proceed to install the dependencies by running the following command: ```elixir mix deps.get ``` To use Urlbox, you'll need to create an account and get a pair of API credentials. The registration process is straightforward, only asking for an email and password. Once registered, you can retrieve your API credentials directly from the dashboard. ![Urlbox credentials](/content/how-to-take-website-screenshots-elixir/HkXfsaO.png) Grab the credentials from the dashboard and add them to the `.env` file: ``` URLBOX_API_KEY="YoUrApIKeY" URLBOX_API_SECRET="YoUrApISeCreT" ``` Next, you'll have to configure the project to pull the credentials from the `.env` file. Go into the `urlbox_example` directory, and create a new configuration file called `config/config.exs`: ```bash mkdir config touch config/config.exs ``` Add the following to the `config/config.exs` file: ```elixir import Config config :ex_urlbox, api_key: {:system, "URLBOX_API_KEY"}, api_secret: {:system, "URLBOX_API_SECRET"} ``` This will automatically pull the credentials from the environment variables. #### Taking Screenshots Next, you'll add the main logic to the `lib/urlbox_example.ex` file: ```elixir defmodule UrlboxExample do @moduledoc """ Documentation for `UrlboxExample`. """ def take_screenshot(url, options \\ [format: "png"]) do {:ok, screenshot} = ExUrlbox.get(url, options) screenshot.url end end ``` Then you can open your REPL and run the following command to take a screenshot of the website: ```elixir UrlboxExample.take_screenshot("https://techcrunch.com/") ``` Unlike previous examples, this time around, we go add a Urlbox url to our screenshot, like `https://api.urlbox.com/v1/S6vqoSXoPaKZCVjd/0d1a4c912dc683784022d993a5fc45c1c73a2062/png?url=https%3A%2F%2Ftechcrunch.com%2F` ![Screenshot with Urlbox](/content/how-to-take-website-screenshots-elixir/0fslEkZ.png) Urlbox is doing all the heavy lifting for us, even storing the resulting screenshot. But this is not all we can do with Urlbox, as it provides some [advanced features](https://urlbox.com/docs/options.md) that go beyond just taking a screenshot. Let's try some of them out by running the following command: ```elixir UrlboxExample.take_screenshot("https://www.geeksforgeeks.org/", [format: "pdf", full_page: true, timeout: 100000]) ``` For this request, we added a few additional options: - **format:** Instead of saving our screenshot as a JPEG or PNG, we are saving the results of the scrapper as a PDF. - **full\_page:** This instructs Urlbox to render the full page from header to footer. - **timeout:** This increases the time that Urlbox will wait for the page to finish rendering before timing out. This results in a full-page PDF generated with the contents of the page. ![Full PDF capture](/content/how-to-take-website-screenshots-elixir/iJUBPI7.png) This kind of flexibility and power opens many different use cases, from the ones covered at the beginning of the article to potential uses in ad-tech to generate advertising assets by converting websites and spreadsheets to sharable PDFs. ## Conclusion In this article, you've learned about three distinct ways of taking screenshots with Elixir, from PuppeteerImg, the most limited approach, to a much more flexible approach using [Urlbox](https://urlbox.com/.md). You've also covered the drawbacks and considerations for the main approaches, and how relying on tools like Puppeteer and Selenium will require special care when deploying your application to production. --- # How to Take Website Screenshots With Java > In this tutorial, you'll learn how to take screenshots in Java using different methods. Source: https://urlbox.com/website-screenshots-java Last updated: 2025-03-21 --- As a Java programmer, there are many times that you may want to take a screenshot programmatically. For example, when writing automation tests, you may want to take screenshots to store and evaluate the test results. Other use cases could include saving an image of dynamic, user-generated web pages, or monitoring pages that have used your own brand’s assets to showcase a product. In this tutorial, you'll learn how to take screenshots in Java using different methods. You’ll learn how to create a Java project, and set up an application that can be used to take screenshots of websites programmatically. ## Taking Screenshots With Java You'll need a few things to follow along with this tutorial. Sign up for a [Urlbox](https://urlbox.com/.md) account—the free trial is fine. Once you've registered your account, go to your Urlbox [user dashboard](https://urlbox.com/dashboard.md), and make a note of your API key and API secret, as shown below. ![Urlbox dashboard](/content/how-to-take-website-screenshots-with-java/3drysTV.png) You'll also need an IDE for Java. The examples here use the [IntelliJ IDEA](https://www.jetbrains.com/idea/) community version, but you can use any IDE you want. Finally, you'll need the URL of the website you'd like a screenshot of. You can find the code used in this article in this [GitHub repository](https://github.com/See4Devs/screenshot-java). ### Setting Up the Demo Project For this tutorial we are using Java version 12, so make sure you have a JRE installed on your machine [JRE Installation Guide](https://docs.oracle.com/goldengate/1212/gg-winux/GDRAD/java.htm#BGBFJHAB). Open IntelliJ, then click on a **New Project**, then select **Maven**. ![Java new Maven project](/content/how-to-take-website-screenshots-with-java/RlUB9z9.png) - Click **Next**, then add the GroupId and the ArtifactId, then click on **Finish**. ![Adding the GroupId and ArtifactId](/content/how-to-take-website-screenshots-with-java/SBEQn5M.png) Once you've done that, you should have a basic project structure with default settings. ![Default project structure](/content/how-to-take-website-screenshots-with-java/ZbkmTm1.png) In the Java project you've just created, create new packages named `services’ and `main’. The package will be used to create a group of related classes. To create a package, right-click on the **java** folder, go to **New**, and then **Package**. ![Adding new package](/content/how-to-take-website-screenshots-with-java/rZY3G7H.png) This completes the basic project setup. ![Basic project setup completed](/content/how-to-take-website-screenshots-with-java/iXjddV6.png) ### Taking a Screenshot Using Selenium With the Chrome Driver [Selenium](https://www.selenium.dev/) is an open source project for a range of tools. It helps you create robust, browser-based automation tests. It’s commonly used by quality assurance engineers, who write scripts for automating application tests rather than doing the work manually. We will be using Selenium with the Chrome driver to open a website URL in a browser programmatically, take a screenshot, then close the browser. To start using Selenium, add the following maven dependencies to your `pom.xml`: ```java <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-io</artifactId> <version>1.3.2</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>2.42.2</version> <scope>compile</scope> </dependency> ``` Once added, the dependencies should start to download automatically. In order to open the browser programmatically and use Selenium library to interact with it, you'll need to install the following: - The [Chrome Browser](https://www.google.com/chrome/) - The [Chrome driver](https://chromedriver.chromium.org/downloads), which we'll use with the Selenium library to be able to communicate with Google Chrome. Choose a Chrome driver version that is compatible with your Chrome browser version. To make things easier for this tutorial, you can put your Chrome driver at the root of your project directory under ‘screenshot-java’. Create the class `UrlSelenium` under the package services, and copy-paste the code below. This class will contain the methods that will be used to take a screenshot using Selenium and the Chrome driver. ```java package services; import java.io.File; import java.io.IOException; import org.apache.commons.io.FileUtils; import org.openqa.selenium.OutputType; import org.openqa.selenium.Point; import org.openqa.selenium.TakesScreenshot; import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; public class UrlSelenium { private int screenshotNum=0; private WebDriver driver=null; public UrlSelenium(int screenshotNum, WebDriver driver) { this.driver = driver; this.screenshotNum = screenshotNum; } public void initDriver() { System.setProperty("webdriver.chrome.driver", "chromedriver"); this.driver=new ChromeDriver(); this.driver.manage().window().setPosition(new Point(-2000, 0)); } public void capture(String site) throws IOException { this.screenshotNum++; this.driver.get(site); File scrFile = ((TakesScreenshot)this.driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(scrFile, new File("selenium-"+screenshotNum+".png")); System.out.println("Took Screenshot for "+site+" and saved as "+"site"+screenshotNum+".png"); } public void destroy() { this.driver.quit(); } } ``` In the above code, we have the following methods: - **`initDriver()`**: A function that will initiate the Chrome driver by creating a new instance of ChromeDriver() and setting its position. - **`capture(String site)`:** A function that takes the site URL as input, then generates a screenshot image of the selected site and saves it into the root directory of the project. - **`destroy()`:** A function that stops the Chrome driver from running. Create the class `ScreenShotCaptureSelenium` under the package main, and copy-paste the code below. This class contains the main method that will take the screenshot using Selenium. ```java package main; import java.io.IOException; import services.UrlSelenium; import org.openqa.selenium.WebDriver; public class ScreenShotCaptureSelenium { static int screenshotNum=0; static WebDriver driver=null; public static void main(String[] args) throws IOException { UrlSelenium selenium = new UrlSelenium(0, null); selenium.initDriver(); selenium.capture("https://www.google.com"); selenium.capture("https://facebook.com"); selenium.destroy(); } } ``` The code above does the following : - Creates a new instance of our class `UrlSelenium`. - Initiates the chrome driver. - Take two screenshots, one of [Google](http://www.google.com) and one of [Facebook](http://www.facebook.com). - Stop the Chrome driver. Now, run the above main class by right-clicking and selecting **Run**. You will notice that after IntelliJ compiles the code, screenshot images of Google and Facebook get generated under your project directory. The screenshots look like this: ![Screenshot of Google](/content/how-to-take-website-screenshots-with-java/Ceu0K0c.png) ![Screenshot of Facebook](/content/how-to-take-website-screenshots-with-java/th6RnQC.png) While these screenshots look fine, taking a screenshot of a scrollable page might be tricky using Selenium, as would getting an effective screenshot of a page that had popups or cookie banners. Selenium isn't an out-of-the-box solution, and while you could customize the output, it would require significantly more resources and development to do so. ### Taking a Screenshot Using GrabzIt [GrabzIt](https://grabz.it/) is a tool that enables companies to capture screenshots from URLs and convert them into images, PDFs, .docx files, CSV files, and more. The tool features an API that you can use in your application to generate screenshots. To start using GrabzIt, add the following maven dependencies to your `pom.xml`: ```java <dependency> <groupId>it.grabz.grabzit</groupId> <artifactId>grabzit</artifactId> <version>3.5.2</version> </dependency> <dependency> <groupId>com.sun.xml.bind</groupId> <artifactId>jaxb-core</artifactId> <version>2.3.0.1</version> </dependency> <dependency> <groupId>javax.xml.bind</groupId> <artifactId>jaxb-api</artifactId> <version>2.3.1</version> </dependency> <dependency> <groupId>com.sun.xml.bind</groupId> <artifactId>jaxb-impl</artifactId> <version>2.3.1</version> </dependency> <dependency> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> <version>3.25.0-GA</version> </dependency> ``` Once added, the dependencies should start to download automatically. Go to the GrabzIt website and [create a new account](https://grabz.it/login/create), then sign in to your account. Navigate to **Documentation**, and scroll down to get your API key and API secret. ![GrabzIt credentials](/content/how-to-take-website-screenshots-with-java/b79PHbp.png) Create the class `ScreenShotGrabzIt` under the package main, and copy-paste the code below. This class contains the main method that will take the screenshot using GrabzIt. Run the above main class by right-clicking it, then selecting **Run**. You will notice that after IntelliJ compiles the code, a screenshot of Tesla's website will appear in your project directory. ![GrabzIt image result](/content/how-to-take-website-screenshots-with-java/ppe54LT.jpeg) As you can see, this probably isn't quite what you'd hoped to capture. The location selection list is foregrounded, and the rest of the page is unreadable. Additionally, if you want to take a full-page screenshot using GrabzIt, you'll find that it's fairly tricky—you can’t do it dynamically without knowing the dimensions of the page you're trying to screenshot, as shown below: ```java package main; import it.grabz.grabzit.GrabzItClient; import it.grabz.grabzit.parameters.ImageOptions; public class ScreenShotGrabzIt { // main method demos Example Usage of GrabzIt public static void main(String[] args) throws Exception { GrabzItClient grabzIt = new GrabzItClient("Your Application Key", "Your Application Secret"); ImageOptions options = new ImageOptions(); options.setBrowserHeight(1200); options.setBrowserWidth(1200); grabzIt.URLToImage("https://www.tesla.com", options); //Then call the Save or SaveTo method grabzIt.SaveTo("tesla-grabzIt.jpg"); } } ``` ### Taking a Screenshot Using Urlbox Urlbox is a simple and focused [website screenshot API](https://urlbox.com/screenshot-api.md). It supports full-page screenshots as a single image, and responsive screenshots that allow you to simulate different screen sizes—it even allows you to pass a user-agent string to take a screenshot of mobile-optimized sites. You can fine tune the look of your screenshots by blocking specific sections, dismissing cookie banners, and blocking popups and ads. When using the Urlbox API, there's no need to write a single line of JavaScript, or to deploy and maintain a Node application. Create the Java class `ScreenShotUrlBox` under the main package that will contain the main method. Under the services package, create the `Urlbox` class, where you'll define the utility methods that generate the URL. Copy and paste the below code inside the `Urlbox` class: ```java package services; import javax.crypto.Mac; import javax.crypto.spec.SecretKeySpec; import java.io.UnsupportedEncodingException; import java.net.URLEncoder; import java.security.InvalidKeyException; import java.security.NoSuchAlgorithmException; import java.util.HashMap; import java.util.Map; public class UrlBox { private String urlboxKey; private String urlboxSecret; public UrlBox(String urlboxKey, String urlboxSecret) { this.urlboxKey = urlboxKey; this.urlboxSecret = urlboxSecret; } public String generateUrl(String url, Map<String, Object> options) throws UnsupportedEncodingException { String encodedUrl = URLEncoder.encode(url, "UTF-8"); String queryString = String.format("url=%s", encodedUrl); for (Map.Entry<String, Object> entry : options.entrySet()) { String queryParam = "&" + entry.getKey() + "=" + entry.getValue(); queryString += queryParam; } String token = generateToken(queryString, this.urlboxSecret); String result = String.format("https://api.urlbox.com/v1/%s/%s/png?%s", this.urlboxKey, token, queryString); //System.out.println(result); return result; } private String generateToken(String input, String key) { StringBuilder lSignature = new StringBuilder(); try { final Mac lMac = Mac.getInstance("HmacSHA256"); final SecretKeySpec lSecret = new SecretKeySpec(key.getBytes(), "HmacSHA256"); lMac.init(lSecret); final byte[] lDigest = lMac.doFinal(input.getBytes()); // final StringBuilder lSignatureBuilder = new StringBuilder(); for (byte b : lDigest) { lSignature.append(String.format("%02x", b)); } return lSignature.toString().toLowerCase(); } catch (NoSuchAlgorithmException lEx) { throw new RuntimeException("Problems calculating HMAC", lEx); } catch (InvalidKeyException lEx) { throw new RuntimeException("Problems calculating HMAC", lEx); } } }; ``` Urlbox's API accepts different [options](https://urlbox.com/docs/options.md) to customize the screenshot. Some of the options are width, height, thumb\_width, full\_page, block\_ads, and block\_cookie\_banners. These options are passed in a map with a key-value pair. You can use the URL that you’d like a screenshot of and the options map to generate the API URL. Below are the details about the steps involved in the `generateURL()` method To make sure the website URL contains valid characters, we need to encode it into UTF-8 format. Some URLs, especially when they're search results, include special characters in the URL. By encoding the URL, you'll convert these special strings into a valid URL format that the browser can resolve. After encoding, we need to prepend the key `url=` to the encoded URL. Use a `for` loop to iterate through the options map and create a query parameter string for our options. For example, `thumb_width=240&full_page=true&width=1280 &force=false&height=1024`. These parameters will be injected to the URL so that when we make the API call to the Urlbox provider, it will be able to identify what we have selected. Once the query string is available, you need to generate a unique token using the query string and the API secret key. The utility method `generateToken()` generates the token to authenticate the request to the Urlbox API using the utility methods available in the `javax.crypto` package. This is done to check the integrity of information transmitted over an unreliable medium based on a secret key. To generate the full API URL, you need the following information: - The Urlbox base URL, which is `https://api.urlbox.com/v1/` - Api Key - Token - Desired screenshot format, such as PNG or JPG - Query string A URL can be generated in this format using `String.format("https://api.urlbox.com/v1/%s/%s/png?%s", this.urlboxKey, token, queryString);`. Now you have a valid URL that can be assigned to sources where the screenshot image needs to be stored. The class `ScreenShotUrlBox` is where the screenshot taking process lives. Copy and paste the below code inside the `ScreenShotUrlBox` class under the main package: ```java package main; import services.UrlBox; import java.io.IOException; import java.io.InputStream; import java.io.UnsupportedEncodingException; import java.net.MalformedURLException; import java.net.URL; import java.nio.file.Files; import java.nio.file.Paths; import java.util.HashMap; import java.util.Map; public class ScreenShotUrlBox { // main method demos Example Usage public static void main(String[] args) { String urlboxKey = "Add You Key Here"; String urlboxSecret = "Add Your Secret Here"; // Set request options Map<String, Object> options = new HashMap<String, Object>(); options.put("width", 1280); options.put("height", 1024); options.put("thumb_width", 240); options.put("full_page", "true"); options.put("force", "false"); // Create URL box object with API key and secret UrlBox urlbox = new UrlBox(urlboxKey, urlboxSecret); try { // Call generateUrl function of urlbox object String urlboxUrl = urlbox.generateUrl("https://draft.dev", options); // Now do something with urlboxUrl.. put in an img tag, etc.. System.out.println(urlboxUrl); //save image locally try (InputStream in = new URL(urlboxUrl).openStream()) { Files.copy(in, Paths.get("draft-urlBox.png")); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } catch (UnsupportedEncodingException ex) { throw new RuntimeException("Problem with url encoding", ex); } } } ``` The above code goes through the following steps to take a screenshot: - Defines the Urlbox API key and the API secret key. - Sets request options in a map as a key-value format. - Creates an instance of type `Urlbox`, then invokes the `generateURL()` method with the desired URL and options map. The resultant URL will contain a valid API URL. - Stores the screenshot locally, which will be stored by default under your main project directory. Now, run the above main class by right-clicking and selecting **Run**. You'll notice that after IntelliJ compiles the code, a screenshot of the full webpage will be saved in your project directory. ![Urlbox image result](/content/how-to-take-website-screenshots-with-java/geLX8nk.png) ## Conclusion In this tutorial, you've created several simple Java programs using tools like Selenium, GrabzIt, and Urlbox to take screenshots programmatically. UrlBox stands out from tools like Selenium and GrabzIt because it also offers out-of-the-box features such as high-DPI images that look great on retina screens, popup blocking, automatic dismissal of cookie banners to prevent them spoiling your screenshots, ad blocking, and automatic CAPTCHA bypass. Handling issues like this with other tools is time-consuming and costly, and requires writing extensive custom code—if it's possible at all. [Urlbox](https://urlbox.com/.md) is a fast and accurate screenshot rendering service at scale. It offers many options, such as blocking ads and popups, or even changing the appearance of a page with custom CSS or JavaScript. If you need a seamless screenshot solution that integrates into your workflow, give Urlbox a try. --- # How to Convert HTML to PDF in Python > There are lots of tools on the market that make it relatively easy to convert your HTML documents and web pages to PDF. Source: https://urlbox.com/html-to-pdf-python Last updated: 2022-12-14 --- Converting an HTML document to PDF allows you to, at minimum, view the document offline, but some advanced PDF readers allow you to edit, highlight, strikethrough, and comment in the PDF as well. PDFs are superior to HTML documents when it comes to sharing (not to mention printing, should the need for a hard copy arise) because their formatting stays consistent regardless of the device you use to view them. There are lots of tools on the market that make it relatively easy to convert your HTML documents and web pages to PDF—some are free to use, some are open source, and some have good community support. Let’s take a look at a few, so you can come to your own conclusions about which methods would best serve your needs. ## pdfkit [pdfkit](https://pypi.org/project/pdfkit/) is a Python wrapper library for [wkhtmltopdf\`](https://wkhtmltopdf.org/). This library has a relatively simple-to-use API; you can integrate it into a much bigger software project or as part of an automation script to generate PDFs from HTML documents or web pages. ### Installation Since pdfkit relies on wkhtmltopdf under the hood, you need to install wkhtmltopdf first. For Debian/Ubuntu users: ```bash sudo apt-get install wkhtmltopdf ``` For macOS users: ```bash brew install homebrew/cask/wkhtmltopdf ``` Windows users can download the [installer from wkhtmltopdf](https://wkhtmltopdf.org/downloads.html). After a successful installation, you can go ahead and install pdfkit via pip or pip3 (for Python3 users). ```bash pip3 install pdfkit ``` ### Usage After you’ve successfully installed pdfkit, you can write the script for converting HTML to PDF. pdfkit gives you the option of three HTML sources: - For HTML text or string source: `pdfkit.from_string` - For HTML file source: `pdfkit.from_file` - For a URL source: `pdfkit.from_url` Here’s a sample script to illustrate how pdfkit works; just for the fun of it, let’s assume that I’m researching some of the world's biggest entrepreneurs. ```py import pdfkit pdfkit.from_url("https://en.wikipedia.org/wiki/Elon_Musk", "elon1.pdf") ``` And here's an image of the resulting PDF: ![Image of generated Elon's PDF using pdfkit](/content/html-to-pdf-python/QHkYOE4.png) ## pyhtml2pdf [pyhtml2pdf](https://pypi.org/project/pyhtml2pdf/) is a simple python wrapper to convert HTML to PDF with headless Chrome via Selenium. ### Installation pyhtml2pdf depends on an installation of the Chrome browser or [ChromeDriver](https://chromedriver.chromium.org/downloads). After making sure that either is installed, proceed to install the pyhtml2pdf Python package. ```bash pip3 install pyhtml2pdf ``` ### Usage After a successful installation of pyhtml2pdf, go ahead and write a Python script to convert an HTML document to PDF. Let’s continue with the Wikipedia example in the previous example and create a file called `script.py`. ```py from pyhtml2pdf import converter converter.convert("https://en.wikipedia.org/wiki/Elon_Musk", "elon2.pdf") ``` ```bash python3 script.py ``` After running the script, I got this output: ![Image of generated Elon's PDF using pyhtml2pdf](/content/html-to-pdf-python/QrhHZVs.png) ## DocRaptor Unlike the previous tools we’ve covered, [DocRaptor](https://docraptor.com/) is a cloud-based service. Thanks to a robust infrastructure, it should be able to handle a large number of requests and conversions. Docraptor also gives you the ability to add headers, footers, page breaks, page numbers, and a table of contents to your final PDF. > DocRaptor is not an entirely free service, although it does have a free tier in its subscription plan. However, note that the free tier allows only five conversions per month. To get started with DocRaptor, [create an account](https://app.docraptor.com/signup) with the free tier subscription plan. DocRaptor also provides an SDK for popular platforms and programming languages such as PHP, Python, Node, Ruby, Java, .Net, and JQuery. ### Installation After creating your DocRaptor account, you’ll need to install the SDK; this example uses the Python SDK. ```sh pip3 install --upgrade docraptor ``` After running the above successfully, DocRaptor should be installed. ### Usage Now that you have DocRaptor installed, the next step is to write the script that will interact with DocRaptor’s web service through their API. ```py import docraptor doc_api = docraptor.DocApi() doc_api.api_client.configuration.username = "<API_KEY>" response = doc_api.create_doc({ "test": False, "document_url": "https://en.wikipedia.org/wiki/Elon_Musk", "name": "elon3.pdf", "document_type": "pdf" }) ``` After writing and running this sample script, you should see your conversion history on your document history page. ```sh python3 script.py ``` ![Docraptor document history](/content/html-to-pdf-python/5Rh08FS.png) Click **Details** to see more about a particular conversion. ![Docraptor converted document details](/content/html-to-pdf-python/UiOS5HW.png) From the conversion timeline on the right side of the page, click the download link to download your converted PDF. ![A DocRaptor converted document](/content/html-to-pdf-python/oXoDt2E.png) ## Urlbox [Urlbox](https://urlbox.com/.md) is a service that handles a lot of edge cases inherent to complex web pages and HTML documents, so it offers a lot of customization to achieve your desired result. It not only allows you to convert HTML and URLs to PDFs, but images as well. First, [create a free account](https://urlbox.com/pricing.md) and get your API key. Next, log into your new Urlbox account and navigate to the dashboard. ![Urlbox dashboard](/content/html-to-pdf-python/sCUMPdk.png) In your dashboard, you will see your publishable and secret API keys for making requests to the Urlbox API. ### Installation The next step is to install Urlbox SDK via an HTTP library with a `GET` request. ### Usage To start converting an HTML doc to a PDF, you first need to understand the URL structure for making requests to the Urlbox API: `https://api.urlbox.com/v1/api-key/format?options`. So let’s break that down: - `api-key` is the publishable key on your dashboard. - `format`can be any of `png`, `pdf`, `jpg`, `jpeg`, `avif`, `webp`, `svg`, `html`. - `options` refers to a query string that contains all the options that you want to set. When you send the HTTP `GET` request, the Urlbox API responds with the binary data of the converted PDF—or any format of your choosing with an HTTP header that has `Content-Type`—to a type corresponding to the `format` in your request. This makes the Urlbox API very flexible. You can enter your URL in your browser and get your converted PDF rendered right in your browser, ready to download. ![Urlbox converted Google.com page](/content/html-to-pdf-python/HsKoqA1.png) You can also write a Python script to utilize the Urlbox API. I’ll be illustrating with [the script provided in Urlbox’s documentation](https://urlbox.com/docs/examplecode/python.md). ![Urlbox sample code](/content/html-to-pdf-python/VN6wlxX.png) The code in the documentation illustrates how to build a query string to make a request to the Urlbox API. You’ll have to introduce the code to actually make the HTTP request. ```py import hmac from hashlib import sha256 from urllib.parse import urlencode import urllib.request def urlbox(args): apiKey = "<YOUR PUBLISHER KEY>" apiSecret = "YOUR SECRET KEY" queryString = urlencode(args, True) hmacToken = hmac.new(str.encode(apiSecret), str.encode(queryString), sha256) token = hmacToken.hexdigest().rstrip('\n') return "https://api.urlbox.com/v1/%s/%s/pdf?%s" % (apiKey, token, queryString) argsDict = {'url' : "https://en.wikipedia.org/wiki/Elon_Musk", 'thumb_width': 400} print(urlbox (argsDict)) response = urllib.request.urlopen(urlbox(argsDict)).read() ``` In the above script, `urllib` is part of Python's standard library for parsing URLs and making HTTP requests. ```sh python3 urlbox.py ``` After running the script, click the **Usage** tab in the dashboard. You should see a page like this: ![Urlbox usage dashboard](/content/html-to-pdf-python/a3c9e2s.png) Under the **Usage Logs** section, click the preview of the first log; it should be the last converted PDF. ![Urlbox converted PDF](/content/html-to-pdf-python/XOYxQMQ.png) You can take a look at the [converted PDF shown in the previous image here](https://api.urlbox.com/v1/ca482d7e-9417-4569-90fe-80f7c5e1c781/1ba7538a05de019cfcddbac1c722aa14c0cec826/pdf?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FElon_Musk\&thumb_width=400). ### Options Now that you’ve seen the basics of Urlbox, let’s take a quick look at some of the [customizations](https://urlbox.com/docs/options.md) you can explore. Buckle up—there’s a lot here, and we don’t get to everything! **Basic Options** The basic options that are available are: - `width`. Sets the browser's viewport width in pixels. - `height`. Refers to the browser's viewport height used to render the HTML that is to be converted to a PDF. - `full_page`. Tells the Urlbox API to cram all the HTML content into a single-page PDF. \**Blocking Options* - `block_ads`. Stops ads from popular advertising networks from loading on the web page to be converted. - `block_urls`. Stops requests from the specified URLs from loading. - `hide_cookie_banner`. Automatically hides cookie banners from most websites. - `click_accept`. Automatically clicks accept buttons in order to dismiss popups. - `hide_selector`. Hides elements by passing a comma-delimited string of CSS element selectors. **Customize Options** You can use these options to customize the look of the web page before rendering a screenshot: - `js`. Injects and executes custom JavaScript on the web page before rendering. - `css`. Injects custom CSS into the web page. - `dark_mode`. Emulates dark mode on most websites by setting `prefers-color-scheme: dark`. - `reduced_motion`. Sets the preference of the website's animation to `prefers-reduced-motion: reduced`. **Image Options** These options customize the output of PNG, JPEG, or WebP files: - `retina`. Takes a high-definition screenshot, equivalent to setting a device pixel ratio of 2.0. Note that the processing time will be longer than usual. - `thumb_height`. Sets the height of the generated thumbnail in pixels it can be omitted for a full-sized screenshot. - `thumb_width`. Sets the width of the generated thumbnail in pixels it can also be omitted for a full-sized screenshot. - `quality`. Sets the image quality of the resulting screenshot for JPEG and WebP only. - `transparent`. Renders the resulting screenshot with a transparent background, if the web page has no background color set. - `max_height`. Useful for extremely lengthy websites. However, you might want to consider limiting the screenshot to a maximum height to prevent Urlbox from scrolling a long time just to generate an enormous screenshot. - `download`. Makes the resulting Urlbox link downloadable you’ll be prompted to save the file with the filename passed with the `download` query parameter. **PDF Options** These are options relating to PDF generation: - `pdf_page_size`. Sets the PDF page size available options include `A0`–`A6`, `Legal`, `Letter`, `Ledger`, and `Tabloid`. Note that setting `pdf_page_size` takes precedence over `pdf_page_width` and `pdf_page_height`. - `pdf_page_width` and `pdf_page_height`. Set the width and height of the PDF in pixels respectively. - `pdf_margin`. Sets the margin of the PDF with three available options: `none`, `default`, and `minimum`. - `pdf_margin_top`, `pdf_margin_right`, `pdf_margin_bottom`, `pdf_margin_left`. Set custom margins in pixels on the PDF. - `pdf_scale`. Sets the scale factor on the website content on the PDF valid values are numbers between 0.1 and 2. - `pdf_orientation`. Sets the orientation of the generated PDF to either `portrait` or `landscape`. - `pdf_background`. Sets background images to print in the generated PDF. By default, when generating a PDF, the `print` CSS media query is used. To generate a PDF using the `screen` CSS, set this option to `screen`. **Cache Options** These options determine how Urlbox caches your screenshots or PDFs: - `force` - `unique` - `ttl` **Request Options** These configure the browser before navigating to the URL: - `proxy` - `header` - `accept_lang` - `authorization` - `user_agent` - `cookie` **Wait Options** These give you the ability to control the length of the wait before carrying out certain actions: - `delay` - `timeout` - `wait_until` - `wait_for` - `wait_to_leave` - `wait_timeout` **Page Options** These modify the page state before taking a screenshot: - `scroll_to` - `click` - `click_all` - `hover` - `bg_color` - `disable_js` **Full Page Options** These advanced options control how Urlbox takes full-page screenshots, when `full_page=true`. Available options are: - `allow_infinite` - `full_width` - `skip_scroll` - `detect_full_height` - `max_section_height` - `scroll_increment` - `scroll_delay` - `turbo` **Highlighting Options** These options highlight a given string on the page. - `highlight`. Selects the string to highlight before capturing the PDF. - `highlightfg`. Specifies the text color of the highlighted word. - `highlightbg`. Specifies the background color of the highlighted word. **Geolocation Options** These options emulate the Geolocation API: - `latitude` - `longitude` - `accuracy` **Storage Options** These options relate to storing the screenshot in Amazon S3: - `use_s3` - `s3_path` - `s3_bucket` - `s3_storagelass` **Request Behavior Options** These dictate how Urlbox handles certain incidents: - `fail_if_selector_missing` - `fail_if_selector_present` - `fail_on_4xx` - `fail_on_5xx` ## Conclusion Obviously, there’s a lot you can do to customize HTML-to-PDF conversion, and there are a lot of tools on the market ready to help you with whatever task you have at hand. No matter what tool you choose, keep in mind that generating PDFs is a job best done by a third-party service. The infrastructure required to generate PDFs at scale can quickly become an undesirable maintenance burden for an engineering team. [Urlbox](https://urlbox.com/.md) in particular has a robust and secure API to help you convert, customize, and manage HTML-to-PDF conversions securely at scale so you’re not distracted from your core product work. --- # How to Convert HTML to PNG Images with Python > If you want to create website screenshots using Python here are some popular options. Source: https://urlbox.com/html-to-png-with-python Last updated: 2023-01-09 --- If you want to create website screenshots using Python here are some popular options: - [Playwright](https://playwright.dev/python/docs/intro) - 2020 release - [Puppeteer](https://pptr.dev/) - 2017 release - not discussed - [Selenium Webdriver](https://www.selenium.dev/documentation/webdriver/) - 2002 release - [Urlbox]() - since 2012 [Sample Code on GitHub](https://github.com/djhmateer/code-python-urlbox-article) showing all the examples in this article ## TL;DR For new projects I will always try [Urlbox](https://urlbox.com/.md) as rendering is difficult for many websites. Their sandbox mode is great to get good feedback and proxying support for testing. For new complex projects I favour [Playwright](https://playwright.dev/python/docs/intro) over [Puppeteer](https://pptr.dev/) as it has official support for Python. [Good discussion](https://www.zenrows.com/blog/playwright-vs-puppeteer#web-scraping-with-playwright) For legacy projects I still support [Selenium]() which is the oldest and most complex to setup. [Good discussion](https://brightdata.com/blog/proxy-101/puppeteer-vs-selenium) ## 1. Playwright [Playwright](https://playwright.dev/python/docs/introsywrightimple) is about testing and it's screenshotting is excellent. > .. the needs of end-to-end testing. Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox. Test on Windows, Linux, and macOS, locally or on CI, headless or headed 7.8k stars on [GitHub - Python release](https://github.com/microsoft/playwright-python) and last release was on the 4th Jan 2023 ie it is an active project. Interestingly the parent [Javascript / Typescript/ Node Project](https://github.com/microsoft/playwright) project as 46k stars and there are [.NET]() and [Java]() implementations too To install follow [the docs](https://playwright.dev/docs/intro) ```bash # I'm using Python 3.8.10 on Ubuntu 20.04 on Windows WSL for dev, Ubuntu 20.04 for production # 22.3.1 pip install --upgrade pip # 1.28.0 is the package version from pip - 1.29.1 is latest on gh repo pip install pytest-playwright # installs required browsers playwright install ``` Let's do the simplest possible thing: ```py from playwright.sync_api import sync_playwright with sync_playwright() as p: browser = p.chromium.launch() page = browser.new_page() page.goto("http://playwright.dev") print(page.title()) browser.close() ``` The output is shown below (VSCode) ![alt text](/content/html-to-png-with-python/vscode.jpg "Title") It got the page title and we're running the 3.8.10 Python interpreter. [Screenshots](https://playwright.dev/python/docs/screenshots) can be done using the `page.screenshot` function: ```py from playwright.sync_api import sync_playwright with sync_playwright() as p: browser = p.chromium.launch() page = browser.new_page() page.goto("http://playwright.dev") # print(page.title()) page.screenshot(path="screenshot.png") browser.close() ``` and the output: ![alt text](/content/html-to-png-with-python/screenshot.jpg "Title") It worked! Notice the default screenshot size is 1280 wide x 720 height [playwright.dev](https://playwright.dev/) is a much longer page ### Fullpage ```py # this time gives 1280x3364 page.screenshot(path="screenshot.png", full_page=True) ``` Sometimes this doesn't work as intended. For the rest of this section I'm showing the most relevant parts of Playwright which have helped me: ```py from playwright.sync_api import sync_playwright with sync_playwright() as p: browser = p.chromium.launch() ua = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.87 Safari/537.36" context = browser.new_context( # Passing a different user agent user_agent=ua, # Forcing a larger viewport to make facebook play well # https://playwright.dev/docs/next/emulation#viewport viewport={"width":1200, "height":2000} ) page = context.new_page() # A public facebook post url="https://www.facebook.com/djhmateer/posts/pfbid0WK2FACHyfyBi1Lg9intnH3SmLHNRYDTfzmGZgjFqSoQAnitAz8ZVdRF1nqmx9JX1l" page.goto(url) page.screenshot(path="screenshot.png") browser.close() ``` The result is as expected. ![alt text](/content/html-to-png-with-python/1200.jpg "Title") A 1200x2000 page showing everying we want. ### Proxy We use [https://brightdata.com/](https://brightdata.com/) for proxying when we want to appear to come from different IP addresses on each request. ```py from playwright.sync_api import sync_playwright from pathlib import Path with sync_playwright() as p: # browser = p.chromium.launch() # read secrets from a directory which isn't checked into git # you will need to create this directory and files username = Path('secrets/proxy-username.txt').read_text() password = Path('secrets/proxy-password.txt').read_text() browser = p.chromium.launch( # Use a proxy to appear as if we're coming from a different IP address each time proxy={ "server": 'http://zproxy.lum-superproxy.io:22225', "username": username, "password": password } ) ua = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.87 Safari/537.36" context = browser.new_context( user_agent=ua, viewport={"width":1200, "height":2000} ) page = context.new_page() # shows user agent and IP address url = "http://whatsmyuseragent.org/" page.goto(url) page.screenshot(path="screenshot.png") browser.close() ``` Resulting screenshot is: ![alt text](/content/html-to-png-with-python/ip.jpg "Title") This IP address is in Israel, and I'm in the UK so the proxy has worked. ### Headed mode Sometimes websites (Facebook!) don't like headless browsers connecting to them, so lets do a Headed (or Headful) connection. We'll need to install an `X Virtual Frame Buffer` as there is no screen for Chrome to render to (especially on the server when we go to production) ```bash # install the virtual frame buffer sudo apt install xvfb # run screenshotter in headed mode xvfb-run python3 6playwright_screenshot_proxy_headed.py ``` then ```py # 6playwright_screenshot_proxy_headed.py from playwright.sync_api import sync_playwright from pathlib import Path with sync_playwright() as p: username = Path('secrets/proxy-username.txt').read_text() password = Path('secrets/proxy-password.txt').read_text() browser = p.chromium.launch( # Playwright runs in headless mode by default # some sites eg Facebook, may not like this # https://playwright.dev/docs/next/debug#headed-mode # we need to run using a virtual xserver headless=False, # Lets use a proxy to appear as if we're coming from a different IP address # each time proxy={ "server": 'http://zproxy.lum-superproxy.io:22225', "username": username, "password": password }, # Start the headed browser window Maximised so that we can get a 1200x2000 viewport args=['--start-maximized'] ) ua = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.87 Safari/537.36" context = browser.new_context( user_agent=ua, viewport={"width":1200, "height":2000} ) page = context.new_page() # a public facebook post # url = "https://www.facebook.com/djhmateer/posts/pfbid0WK2FACHyfyBi1Lg9intnH3SmLHNRYDTfzmGZgjFqSoQAnitAz8ZVdRF1nqmx9JX1l" # shows user agent and IP address url = "http://whatsmyuseragent.org/" page.goto(url) page.screenshot(path="screenshot.png") browser.close() ``` result: ![alt text](/content/html-to-png-with-python/buffer.jpg "Title") The Headed mode worked. ### Clicking Having a popup banner to accept cookies may not be ideal when doing a screenshot, so lets accept then do the screenshot: ```py from playwright.sync_api import sync_playwright from pathlib import Path import time # run using this command # xvfb-run python3 7playwright_screenshot_proxy_headed_click.py with sync_playwright() as p: username = Path('secrets/proxy-username.txt').read_text() password = Path('secrets/proxy-password.txt').read_text() browser = p.chromium.launch( headless=False, proxy={ "server": 'http://zproxy.lum-superproxy.io:22225', "username": username, "password": password }, args=['--start-maximized'] ) ua = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.87 Safari/537.36" context = browser.new_context( user_agent=ua, viewport={"width":1200, "height":2000} ) page = context.new_page() # maybe there will be a cookie popup # so click accept cookies on facebook.com to try to alleviate try: response = page.goto("http://www.facebook.com", wait_until='networkidle') time.sleep(5) foo = page.locator("//button[@data-cookiebanner='accept_only_essential_button']") foo.click() print(f'click done - fb click worked') # linux server needs a sleep otherwise facebook cookie won't have worked and we'll get a popup on next page time.sleep(5) except Exception as e: print(f'Failed on fb accept cookies with {e=}') # a public facebook post url = "https://www.facebook.com/djhmateer/posts/pfbid0WK2FACHyfyBi1Lg9intnH3SmLHNRYDTfzmGZgjFqSoQAnitAz8ZVdRF1nqmx9JX1l" # https://github.com/microsoft/playwright/issues/12182 # sometimes a timeout # wait until all network traffic is done (or enough is done for a good screenshot) response = page.goto(url, timeout=60000, wait_until='networkidle') # detect if there is a 30x redirect # which means that the screenshot would show a login page instead of the intended page if response.request.redirected_from is None: print("all good - no redirect") page.screenshot(path="screenshot.png") browser.close() else: print(f'normal control flow. redirect to login problem! This happens on /permalink and /user/photo direct call {response.request.redirected_from.url}') browser.close() ``` ![alt text](/content/html-to-png-with-python/click.jpg "Title") The accept cookies click worked, we've got a nice big page of 1200x2000, and we've screenshotted the public Facebook page. ## 2. Selenium Webdriver (Firefox) All major legacy browsers are supported (Firefox, Chrome, Internet Explorer). I'm including this as I [support code](https://github.com/bellingcat/auto-archiver) which uses this. [pypy Selenium](https://pypi.org/project/selenium/) [Mozilla Geckodriver](https://github.com/mozilla/geckodriver/releases) - 0.32.0 - 2022-10-13 ```bash # Python Language Bindings - selenium-4.7.2-py3 - 2nd Dec 2022 pip3 install selenium # Install browser sudo apt install firefox -y # Selenium requires a driver to interface with Firefox # Gecko driver # check version numbers for new ones cd ~ wget https://github.com/mozilla/geckodriver/releases/download/v0.31.0/geckodriver-v0.31.0-linux64.tar.gz tar -xvzf geckodriver* chmod +x geckodriver sudo mv geckodriver /usr/local/bin/ # unicode font support eg Burmese characters sudo apt install fonts-noto -y ``` [Unicode fonts on Stackoverflow](https://stackoverflow.com/questions/36490461/selenium-firefoxdriver-gettext-utf-8-encoding) then ```py from selenium import webdriver options = webdriver.FirefoxOptions() options.headless = True driver = webdriver.Firefox(options=options) driver.set_window_size(1400, 2000) # Navigate to Facebook driver.get("http://www.facebook.com") # save a screenshot driver.save_screenshot("screenshot.png") ``` ![alt text](/content/html-to-png-with-python/sel.jpg "Title") So this works in a similar way to Playwright ### Clicking ```py from selenium import webdriver import time from selenium.webdriver.common.by import By options = webdriver.FirefoxOptions() options.headless = True driver = webdriver.Firefox(options=options) driver.set_window_size(1400, 2000) # Navigate to Facebook driver.get("http://www.facebook.com") # click the button: Allow Essential and Optioanl Cookies foo = driver.find_element(By.XPATH,"//button[@data-cookiebanner='accept_only_essential_button']") foo.click() # now am logged in, go to original page driver.get("https://www.facebook.com/watch/?v=343188674422293") time.sleep(6) # save a screenshot driver.save_screenshot("screenshot.png") ``` ![alt text](/content/html-to-png-with-python/sel2.jpg "Title") Correct screen size, correct rendering of UTF-8 fonts. However I've done a simple sleep for 6 seconds instead of waiting for all network requests to end. Playwright provides greater control. We have found that doing many renders can cause memory leaks, so it is a good idea to destroy and recreate on each render. ## 3. Urlbox Screenshot as a Service API [urlbox](https://urlbox.com/.md) makes it much easier to render website screenshots without having to worry about low level infrastructure `<notetoself>` which I do love, however sometimes you need to get things done, make money, and hit deadlines.. not mess around `</notetoself>` Signup to urlbox is free and fast. ![alt text](/content/html-to-png-with-python/sand.jpg "Title") The sandbox is a perfect place to explore what urlbox can do. [https://time.is/](https://time.is/) is a good test as it is a long page (which is chopped above), shows the location of the caller - in this case Oregon. This is where urlbox initiated this request. ### API [Urlbox docs](https://urlbox.com/docs/getting-started.md) is a good starting place. There is a handy [PyPi Urlbox package](https://pypi.org/project/urlbox/) and [GitHub source](https://github.com/urlbox/urlbox-python). I've got an [Open Issue](https://github.com/urlbox/urlbox-python/issues/51) about a conflict as it uses requests 2:26.0. I worked around it, but if you have any issues, leave a message on the issue and I'll try to help. ```bash # 1.0.6 - Dec 2021 pip install urlbox ``` then ```py from urlbox import UrlboxClient from pathlib import Path # create a secrets directory and text files with your details in api_key = Path('secrets/urlbox-api-key.txt').read_text() api_secret = Path('secrets/urlbox-api-secret.txt').read_text() urlbox_client = UrlboxClient(api_key=api_key, api_secret=api_secret) # Make a request to the Urlbox API url = "https://time.is/" # notice options in screenshot above # easy to copy and paste from sandbox to code! options = { "format": "png", "url": url, } response = urlbox_client.get(options) # save screenshot image to screenshot.png: with open("screenshot.png", "wb") as f: f.write(response.content) ``` [https://urlbox.com/docs/examplecode/python](https://urlbox.com/docs/examplecode/python.md) - shows a lower level way of calling API via http. ### Options ![alt text](/content/html-to-png-with-python/cache.jpg "Title") Usage shows what you've done via the sandbox or API. Interestingly I've done multiple calls to the API while testing but it only shows 1. Caching is turned on by default on the API. ```py from urlbox import UrlboxClient import sys from pathlib import Path api_key = Path('secrets/urlbox-api-key.txt').read_text() api_secret = Path('secrets/urlbox-api-secret.txt').read_text() urlbox_client = UrlboxClient(api_key=api_key, api_secret=api_secret) url = "https://time.is/" options = { "format": "png", "full_page": True, "force": True, # no cache "url": url } response = urlbox_client.get(options) data = response.content try: # if we can decode the response.content then it is an error # as the screenshot we are expecting is binary json_error = str(data, "utf-8") print(json_error) sys.exit() except (UnicodeDecodeError, AttributeError): # can't decode the response.content so it is the screenshot as binary data pass # save screenshot image to screenshot.png: with open("screenshot.png", "wb") as f: f.write(response.content) ``` ![alt text](/content/html-to-png-with-python/cache2.jpg "Title") API worked giving me back a full screen image, not cached. ### Proxy Lets use [https://brightdata.com/](https://brightdata.com/) as a proxy [Urlbox proxy docs](https://urlbox.com/docs/options.md#proxy) shows the format we need to pass: `[user]:[password]@[address]:[port]` ```py from urlbox import UrlboxClient import sys from pathlib import Path api_key = Path('secrets/urlbox-api-key.txt').read_text() api_secret = Path('secrets/urlbox-api-secret.txt').read_text() urlbox_client = UrlboxClient(api_key=api_key, api_secret=api_secret) proxy_username = Path('secrets/proxy-username.txt').read_text() proxy_password = Path('secrets/proxy-password.txt').read_text() url = "https://time.is/" proxy = f"{proxy_username}:{proxy_password}@zproxy.lum-superproxy.io:22225" options = { "format": "png", "url": url, "force": True, # no cache "full_page": True, "proxy": proxy } response = urlbox_client.get(options) data = response.content try: # if we can decode the response.content then it is an error # as the screenshot we are expecting is binary json_error = str(data, "utf-8") print(json_error) sys.exit() except (UnicodeDecodeError, AttributeError): # can't decode the response.content so it is the screenshot as binary data pass # save screenshot image to screenshot.png: with open("screenshot.png", "wb") as f: f.write(response.content) ``` result: ![alt text](/content/html-to-png-with-python/sing.jpg "Title") The proxying worked as we're now coming from Singapore. ### Pushing the limits Urlbox has a plethora of advanced features (scroll explore in the sandbox!) including ```json { "format": "png", "url": "https://www.facebook.com/photo/?fbid=1329142910787472&set=a.132433247125117", "force": true, "fail_on_4xx": true, "fail_on_5xx": true } ``` Fail on 4xx and 5xx is very useful. My use case got a bit trickier with detecting a redirect (showing in playwright above), so ultimately I had to resort to that. ## Conclusion I've been screenshotting websites professionally for 5 years. My last foray into Facebook with Playwright took 2 months to get right. In this article we looked at 1. Playwright - the newest of the screenshotting libraries and would recommend for new projects 2. Selenium Webdriver - I support this but wouldn't recommend unless legacy 3. Urlbox - a screenshot as a service API. I would recommend exploring [Urlbox](https://urlbox.com/.md) first to avoid technical headaches.

Tour some key Kubernetes scalability features and their benefits for Puppeteer-powered screenshot APIs. Source: https://urlbox.com/guides/kubernetes-website-screenshots Last updated: 2025-06-09 --- Puppeteer is a popular browser automation tool for remote controlling Chrome and Firefox instances. It lets you build website screenshot APIs by using code to launch a headless browser, navigate to a target page, and capture an image. Puppeteer-based services can be challenging to scale because they're usually resource-intensive. The presence of a full browser install means they also have heavy dependencies. Kubernetes helps make screenshot APIs more scalable by simplifying key tasks such as resource management, network security, and auto-scaling based on actual service usage. It lets you run your [Puppeteer](https://pptr.dev) screenshot solution as containers you can replicate across multiple physical compute nodes. In this article, we're going to tour some key Kubernetes scalability features and explain their benefits for Puppeteer-powered screenshot APIs. We'll develop the container image from our [How to Build a Docker Image for a Website Screenshot Service](https://urlbox.com/guides/docker-website-screenshots.md) article to demonstrate a simple Kubernetes deployment in action. ## Why Use Kubernetes for Puppeteer APIs? [Kubernetes](https://kubernetes.io) is a container orchestration system. It automates the process of deploying, scaling, and managing containers within cloud infrastructure environments. It's an ideal fit for microservices architectures where all your components must be highly available, but also need to be scaled individually. Kubernetes helps solve many of the issues you might encounter when running Puppeteer at scale. Key advantages include: - **Easy Puppeteer operations as a microservice:** The Kubernetes architecture lets you more easily run your Puppeteer API as a standalone microservice alongside your application code. This improves ease of management by allowing components to be scaled, changed, and deployed individually. - **Scale up automatically, based on user activity:** Kubernetes has built-in [autoscaling capabilities](https://kubernetes.io/docs/concepts/workloads/autoscaling). It can start extra replicas of your service as they're required, letting you seamlessly handle spikes in demand. This is particularly important for screenshot services where each request can take several seconds to fulfill. - **Simple scheduled job management:** Kubernetes includes its own [cron job mechanism](https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs) to run containers on a schedule. This lets you easily take website screenshots periodically or process a capture queue, for instance. Projects such as [Kueue](https://kueue.sigs.k8s.io) expand on this functionality. - **Precisely set resource utilization constraints:** Kubernetes has a sophisticated resource management model that lets you control exactly how much CPU and memory your Puppeteer containers can consume. - **Maintain performance for concurrent captures:** The Kubernetes networking layer includes automatic load-balancing to distribute capture requests between your service's replicas. This helps keep overall load low to ensure stable performance at scale. - **Achieve high availability:** Kubernetes makes it easy to deploy multiple replicas of your Puppeteer screenshot API, ensuring there's no service disruption if an instance or a compute node fails. Now let's take a look at the main options available for scaling Puppeteer with Kubernetes. ## Techniques for Scaling Puppeteer on Kubernetes You can use Kubernetes to scale Puppeteer and your Chrome (or Firefox) instances in two key ways: 1. **One browser instance per Puppeteer container:** Under this model, each Puppeteer container runs exactly one browser instance. Containers can still serve multiple requests concurrently by opening new browser pages. 2. **Separate pool of shared browser instances:** With this model, the containers that run Puppeteer code don't host browser instances. Instead, Puppeteer's configured to connect to a browser instance running as a separate service in your cluster. This approach lets you scale your Puppeteer code independently of your browser pool. We're focusing on the first approach in this guide. It's easy to configure and scales well for most use cases. By keeping your Puppeteer code as a tightly scoped microservice, you can minimize any overheads that could affect performance. But if your code is complex, or does more than just call Puppeteer, then you may benefit from decoupling your browser and Puppeteer containers using the second approach. When scaling Puppeteer, it's also important to plan how you’ll manage browser state. Different browser instances operate independently of each other, so cookies, sessions, and local storage created by a browser running in one container won't be available if a second request lands with another container. This won't typically be an issue if your service simply takes a URL, then captures a screenshot as the public sees it. However, you'll need to enable Kubernetes [sticky sessions](https://kubernetes.io/docs/concepts/services-networking/service/#session-stickiness) for your service if users are allowed to login to websites before requesting a series of captures. ## Guide: Scaling Puppeteer With a Kubernetes Deployment and Service Let's look at a simple demo of how to start a scalable Puppeteer deployment in a Kubernetes cluster. These steps are no different to running any typical web service in Kubernetes, but we'll discuss some Puppeteer-specific best practices in the next section. This guide offers a starting point for new Kubernetes users to understand how to deploy a container image, whether it uses Puppeteer or not. We're using [Minikube](https://minikube.sigs.k8s.io/docs/start) and the sample Puppeteer app and container image available in this article's [GitHub repository](https://github.com/jamesheronwalker/urlbox-puppeteer-kubernetes-demo). You should have Minikube, Docker, and Git installed before you continue. Clone the GitHub repository to get started: `$ git clone https://github.com/jamesheronwalker/urlbox-puppeteer-kubernetes-demo.git` The app within the repository uses Node.js and [Express](https://expressjs.com) to provide a simple HTTP API. Calling the `/capture?url=<url>` endpoint uses Puppeteer to generate a screenshot of the requested URL. The screenshot is provided in the API's HTTP response. You can learn more about the Puppeteer code and Dockerfile in our *How to Build a Docker Image for a Website Screenshot Service* article. Use Docker Compose to build the project's container image: `$ docker compose build` This will build the image and tag it as `urlbox-puppeteer-kubernetes-demo:latest` on your machine. Next, use the `minikube image load` command to make the image available to your Minikube cluster. Minikube can't automatically access the images on your host machine, so the image must be manually loaded unless you've already pushed it to a public container registry. `$ minikube image load urlbox-puppeteer-kubernetes-demo:latest` The image is now ready to use as `urlbox-puppeteer-kubernetes-demo:latest` in your Kubernetes deployments. ### Prepare Your Kubernetes Manifests To run Puppeteer in Kubernetes, you need to create two main resources: 1. **Deployment:** The Deployment object manages a set of Pods to ensure a specified number of replicas is available. 2. **Service:** Kubernetes Services route network traffic to Pods. They provide load balancing between the available replicas. You can find Kubernetes YAML manifest files for the Deployment and Service objects within the `k8s` folder in the sample repository. Here's what the two files look like. #### 1. Deployment ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: puppeteer spec: replicas: 1 selector: matchLabels: app: puppeteer template: metadata: labels: app: puppeteer spec: containers: - name: puppeteer image: urlbox-puppeteer-kubernetes-demo:latest imagePullPolicy: IfNotPresent ports: - containerPort: 3000 ``` This manifest specifies that a single Pod replica (`replicas: 1`) will be deployed initially. We’ll scale this up later on. The Pods run a container called `puppeteer` that uses the image we pushed into the cluster in the step above. Setting `imagePullPolicy` to `IfNotPresent` ensures Kubernetes uses this existing image, rather than trying to pull an update from a non-existing public source. The Deployment manifest specifies a container port of `3000`. This is the port that our Express API service listens on within the container. #### 2. Service ```yaml apiVersion: v1 kind: Service metadata: name: puppeteer spec: type: LoadBalancer selector: app: puppeteer ports: - port: 80 targetPort: 3000 ``` The Service object specifies how traffic reaches the Puppeteer Pods. In this example, we're creating a [`LoadBalancer` service](https://kubernetes.io/docs/concepts/services-networking/service) that can be reached outside the cluster for testing purposes, but other types of Service are available for different use cases. The Service is configured to route traffic to Pods with an `app: puppeteer` label assigned. This label matches that assigned to the Puppeteer Pods by the `template.metadata.labels` field in our Deployment manifest above. The Service's port 80 is then configured to route traffic to port 3000 within the Pods. ### Apply (Deploy) Your Kubernetes Manifests Use the `kubectl apply` command to create the Deployment and Service in your Kubernetes cluster: `$ kubectl apply -f k8s` `deployment.apps/puppeteer created` `service/puppeteer created` You can then use `kubectl get deployment puppeteer` to check that the Pods created by the Deployment are ready: `$ kubectl get deployment puppeteer` `NAME READY UP-TO-DATE AVAILABLE AGE` `puppeteer 1/1 1 1 1m` ### Test Your Service Now you can test the Puppeteer service running in your cluster! First, use `minikube tunnel` to open a network route to your cluster. This emulates having an external load balancer in front of your Kubernetes services. Run the command in a new terminal window, then keep the session open until you’re done testing. `$ minikube tunnel` Next, use the `kubectl get services` command to find the external IP address assigned to your `puppeteer` service: `$ kubectl get services` `NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE` `kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 13m` `puppeteer LoadBalancer 10.100.130.191 10.100.130.191 80:32106/TCP 1m59s` We can see the service has an external IP address of `10.100.130.191`. Visiting `http://10.100.130.191/capture?url=https://www.google.com` in your browser should display a screenshot of the Google homepage, as captured by your Puppeteer API: ![Image showing the successful capture in a browser](/content/kubernetes-website-screenshots/image1.png) ### Scale Your Deployment Finally, you can now scale your Kubernetes Deployment to start additional Puppeteer replicas. Try using the `kubectl scale` command to resize to three replicas: `$ kubectl scale deployment/puppeteer --replicas 3` `deployment.apps/puppeteer scaled` Kubernetes will start new Pods to run your service, improving capacity and redundancy. Use the `kubectl get deployments` command to check the rollout's progress: `$ kubectl get deployments` `NAME READY UP-TO-DATE AVAILABLE AGE` `puppeteer 3/3 3 3 4m` You can then try requesting a new screenshot capture using the same URL as before. The Kubernetes Service model will ensure your requests are transparently load balanced between the three running Pods. ## Best Practices and Strategies for Scaling Puppeteer on Kubernetes The steps above are a simple guide to getting started operating scalable services with Kubernetes. But scalability is much more than manually adjusting replica counts, particularly when it comes to resource-intensive processes like capturing website screenshots with Puppeteer. The following best practices and advanced strategies ensure performant, secure, and maintainable operations for Puppeteer and Kubernetes at scale. ### 1. Use a GitOps-Powered Deployment Model Having developers run `kubectl apply` and `kubectl scale` commands isn't scalable. It’s more efficient to use tools such as [Argo CD](https://argoproj.github.io/cd) and [Flux CD](https://fluxcd.io) to manage your deployments. These tools implement GitOps strategies to automatically update your Kubernetes deployments after you commit changes to your manifest files. Packaging your manifests as a [Helm chart](https://helm.sh) also makes it easier to reuse them across different environments. ### 2. Consider Using a Capture Job Queue Instead of Load Balancing The demo solution shown above scales Puppeteer capacity by load balancing screenshot capture requests across multiple replicas of your app. This isn't always the best way to scale: each replica in our example runs its own browser instance, causing increased resource consumption and higher cluster costs. Modelling your system as a job queue can help make performance more consistent at scale. Instead of having each request capture a screenshot synchronously, add new captures to a queue that your Puppeteer code can pull new jobs from. [Kueue](https://github.com/kubernetes-sigs/kueue) is a popular Kubernetes-native job queuing system that lets you precisely control when jobs start and stop. ### 3. Run Chrome Independently of Your Puppeteer App We discussed this above, but it's worth mentioning again: large-scale systems may be easier to maintain if you host Chrome containers independently of your Puppeteer code. You can then use Kubernetes to separately scale your browser pool and Puppeteer instances. Your browser pool should sit behind a Kubernetes service that your Puppeteer code can connect to using [`connect()`](https://pptr.dev/api/puppeteer.puppeteer.connect). The Service must have [sticky sessions](https://kubernetes.io/docs/reference/networking/virtual-ips/#session-affinity) enabled for this to work (set `spec.sessionAffinity` to `ClientIP` in the Service's manifest). ### 4. Use Kubernetes Network Policies to Restrict Puppeteer API Access Kubernetes Pods can exchange network traffic with any other Pod in your cluster by default. This is a potential security risk—if one Pod is compromised, then it could start sending requests to your Puppeteer service. If you're running your browser instances in separate Pods, then the risk is even higher: a compromised Pod could let attackers directly open a Puppeteer connection to the browser. To mitigate this risk, you must correctly configure [Network Policies](https://kubernetes.io/docs/concepts/services-networking/network-policies) for each Pod you deploy. A Network Policy is a Kubernetes object that specifies which Pods are allowed to communicate with a target Pod. The following basic example restricts Pods labelled `app-component=chrome` so that they can only be reached by other Pods labelled `app-component=puppeteer`. ```yaml apiVersion: networking.k8s.io/v1 kind: NetworkPolicy metadata: name: demo-policy spec: podSelector: matchLabels: app-component: chrome policyTypes: - Ingress - Egress ingress: - from: - podSelector: matchLabels: app-component: puppeteer egress: - to: - podSelector: matchLabels: app-component: puppeteer ``` ### 5. Configure Horizontal Pod Autoscaling to Auto-Scale Puppeteer Based on Load Kubernetes supports automatic horizontal auto-scaling via its [HorizontalPodAutoscaler (HPA) component](https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale). It adjusts your Deployment's replica counts based on actual CPU and memory utilization, ensuring more replicas are created as load increases. HPA will then remove replicas when the load subsides, avoiding excess costs. The following `HorizontalPodAutoscaler` resource will dynamically change the replica count of the `puppeteer` Deployment to maintain an average CPU utilization of 50%. The `minReplicas` and `maxReplicas` fields cap the replica count to ensure there's always at least three, but no more than nine, replicas running. ```yaml apiVersion: autoscaling/v2 kind: HorizontalPodAutoscaler metadata: name: demo-autoscaler spec: scaleTargetRef: apiVersion: apps/v1 kind: Deployment name: puppeteer minReplicas: 3 maxReplicas: 9 metrics: - type: Resource resource: name: cpu target: type: Utilization averageUtilization: 50 ``` HPA is easy to configure using different metrics sources, but other options offer even more precision for advanced use cases. For instance, [Keda](https://keda.sh) allows simple event-driven autoscaling, a concept that's highly applicable to Puppeteer screenshot APIs. You can use it to autoscale your service based on the current number of capture requests or job queue entries, for example. ### 6. Set Correct Resource Requests and Limits for Your Puppeteer and Browser Instances Kubernetes [resource requests and limits](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers) set Pod CPU and memory consumption constraints. It's important to set correct requests and limits so your browser instances have enough resources to capture screenshots performantly, without negatively impacting other workloads in your cluster. Constraints are configured within the `spec.containers[].resources` section of container manifests, such as in the following adaptation of our Deployment resource from above: ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: puppeteer spec: # ... template: metadata: labels: app: puppeteer spec: containers: - name: puppeteer image: urlbox-puppeteer-kubernetes-demo imagePullPolicy: IfNotPresent resources: requests: cpu: 100m memory: 1Gi limits: cpu: 1000m memory: 2Gi ``` This example specifies that the Puppeteer Pods will only schedule onto cluster Nodes that can provide 100 millicores of CPU capacity (0.1 of a logical core) and 1Gi of memory. The Pods can actually consume up to 1000 CPU millicores and 2Gi of memory. If the CPU limit is exceeded, then the Pod will be throttled; if the memory limit is exceeded, then the Pod becomes eligible for termination. Constraints that are too high cause resources to be wasted, but going too low leads to CPU throttling or unexpected Pod out-of-memory events. It's therefore important to analyze your service's actual resource utilization, then refine your requests and limits accordingly. You can also use the optional Kubernetes [vertical pod autoscaler](https://kubernetes.io/docs/concepts/workloads/autoscaling/#scaling-workloads-vertically) component to dynamically change your Pod's requests and limits based on observed conditions in your cluster. ### 7. Use Liveness and Readiness Probes to Prevent Sending Traffic to Non-Ready Containers Puppeteer screenshot capture APIs can take time to become ready to use. You’ll need to wait while the browser launches and Puppeteer acquires a connection, for example. During this time, your service won't be able to successfully handle a capture request. To prevent errors, the Kubernetes Pod shouldn't receive any traffic until it's fully operational. Kubernetes [liveness and readiness](https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes) probes are a mechanism for implementing this functionality. Readiness probes tell Kubernetes when a Pod is ready to begin receiving traffic from Services, while liveness probes enable failures to be detected. To enable these probes for a Puppeteer API, you should provide an API endpoint that Kubernetes can periodically call. The endpoint should indicate whether your Puppeteer service is healthy. For instance, if the browser is running and connected, then you would return a successful response code (2xx). If the browser's not connected, then sending a 4xx or 5xx error status code informs Kubernetes either not to send traffic yet (for readiness probes) or to restart the failed container (for liveness probes). Here's a simple example of a readiness probe configured for the Pods in a Deployment: ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: puppeteer spec: # ... template: metadata: labels: app: puppeteer spec: containers: - name: puppeteer image: urlbox-puppeteer-kubernetes-demo:latest imagePullPolicy: IfNotPresent readinessProbe: httpGet: path: /healthy port: 3000 initialDelaySeconds: 10 periodSeconds: 5 ``` The probe's configuration instructs Kubernetes to make an HTTP GET request to the `/healthy` endpoint served on port 3000 in the container. The `initialDelaySeconds` option defers the first check until 10 seconds after container creation, while the `periodSeconds` option specifies a 5-second delay between subsequent checks until a healthy status is returned. Kubernetes will then start sending traffic to the Pod via Services. ### 8. Implement Robust Monitoring and Alerting As with any service running at scale, continuous monitoring is key to the success of Puppeteer operations. Kubernetes doesn't come configured for observability by default, but it's easy to enable using popular solutions like [kube-prometheus-stack](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack). This runs a Prometheus and Grafana stack inside your cluster. It automates the process of collecting metrics and logs from your Pods and other cluster components. Beyond resource utilization stats, you also need visibility into what's going on within your service. For instance, metrics such as the number of screenshots being generated, success and error rates, and average capture times all help you make more informed scaling decisions. You can instrument your Puppeteer code to [provide these values as Prometheus metrics](https://prometheus.io/docs/instrumenting/clientlibs), ready to scrape alongside your cluster-level monitoring. ## Security Considerations of Scaling Puppeteer on Kubernetes Beyond the best practices discussed above, it's crucial to keep security in mind when running Puppeteer in Kubernetes. Browsers like Chrome and Firefox have a large attack surface. Successfully compromising a zero-day vulnerability could let attackers escape the browser's sandbox to affect your container or surrounding cluster. You can mitigate these risks by applying Kubernetes security protections such as [Pod security contexts](https://kubernetes.io/docs/tasks/configure-pod-container/security-context): ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: puppeteer spec: replicas: 1 selector: matchLabels: app: puppeteer template: metadata: labels: app: puppeteer spec: securityContext: runAsUser: 1001 runAsGroup: 1001 containers: - name: puppeteer image: urlbox-puppeteer-kubernetes-demo:latest imagePullPolicy: IfNotPresent ports: - containerPort: 3000 securityContext: allowPrivilegeEscalation: false ``` Setting a security context lets you ensure your Puppeteer containers run as a non-root user with privilege escalation disabled, even if you forget to specify a non-root user in your Dockerfile. If an attacker escapes the browser, then their ability to cause more damage in the container or cluster will be limited. Similarly, it's important to keep browser sandboxing technologies enabled. Chrome and Firefox isolate web content using sandboxed processes when running as a non-root user. These protections are disabled if you use Puppeteer's `--no-sandbox` launch option, a flag that's commonly found in Puppeteer containerization tutorials. Disabling sandboxing makes it easier to build a functioning Puppeteer Docker image by letting you run the container as the default `root` user, but this effectively eliminates all security protections. When operating a Puppeteer screenshot API, you should also consider the general security implications of letting users capture web content. For instance, users may abuse [SSRF attacks](https://owasp.org/www-community/attacks/Server_Side_Request_Forgery) to try to capture internal services hosted in your cluster, perhaps in combination with DNS rebinding techniques. Improper session isolation could also be exploited to capture content belonging to other users, if your service lets users login and start persistent sessions. ## Summary Puppeteer-based screenshot APIs must be scalable so you can maintain consistent capture performance even during times of high demand. In this article, we've seen how Kubernetes provides a platform for deploying and scaling your Puppeteer services as containers. It lets you use autoscaling, load balancing, and resource requests and limits to ensure stable Puppeteer operations. Even so, there's still significant complexity involved in preparing a Puppeteer container image and then correctly deploying it to Kubernetes. It takes even more work to configure vital capture features such as full-page screenshots, infinite scroll workarounds, and captcha defeats. For an easier option, check out [Urlbox](https://urlbox.com). Our high-performance [website screenshot API](https://urlbox.com/screenshot-api.md) is built to give beautiful results every time. You don't need to maintain your own Puppeteer service or master any scaling settings. Urlbox provides predictable captures with over 100 customization options and built-in ad, popup, captcha, and cookie banner blockers. We even screenshot the challenging elements that don't always work with standard Puppeteer, including canvas elements, videos, and WebGL content.

There are a few different ways we can achieve this with Urlbox Source: https://urlbox.com/screenshot-behind-login Last updated: 2024-07-26 --- # How to Take Automatic, High-Quality Screenshots of Login Protected Sites Urlbox makes it easy to take high quality website screenshots automatically, but have you ever wanted it to be logged in for them? Maybe you want to accumulate some internal dashboards or gather your paywalled articles? There are a few different ways we can achieve this with Urlbox. In this article we'll cover how to: - Copy cookies from a browser session and use them with Urlbox - Include a token as a URL parameter - Use Basic HTTP Authentication - Use authentication headers. You can also log Urlbox in by [injecting custom JavaScript](https://urlbox.com/docs/options#js) or you can fetch the HTML yourself on your server and have [Urlbox render it](https://urlbox.com/docs/options#html), although both are beyond the scope of this article. ## Tokens as a URL Parameter :::note **Warning**: If a site officially supports this method of authentication, you *should* be able to assume it's been safely implemented on the backend. However, if you're considering implementing this for your own site, I'd generally recommend using an `Authorization` header instead; see the next section. ::: One of the simplest ways to authorise Urlbox is with a [URL parameter](https://developer.mozilla.org/en-US/docs/Learn/Common_questions/Web_mechanics/What_is_a_URL#parameters). Just add a question mark, followed by the keys and values to the end of the [`url`](https://urlbox.com/docs/options#url) option as normal. Here's an example: ```bash curl -X POST \ https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer eb31005e820b40b2b34461a698b2b34d' \ -H 'Content-Type: application/json' \ -d ' { "url": "https://non-existent-email-details-page.example.com/email/4568?unrelated_value=bar&email_token=PKsh4mmR9HS9qOfA", "full_page": true, "block_ads": true } ' ``` :::note **Tip**: If you're using Node.js, `URL` objects are a good way to work with URL parameters. For example, here's how you can dynamically set the `email_token`: ```js const urlObjToRender = new URL( "https://non-existent-email-details-page.example.com/email/4568?unrelated_value=bar" ); urlObjToRender.searchParams.set("email_token", generateEmailToken()); const urlToRender = urlObjToRender.toString(); // Use urlToRender in a Urlbox request... ``` ::: ## The Authorization Header and Authorising Urlbox on Your Own Site With the exception of the built in HTTP authentication schemes which I'll get to in a minute, browsers don't send `Authorization` headers when requesting a webpage. So the probably few websites that support this kind of authentication likely do so to enable automatic services like Urlbox, and if it's officially supported, should have API documentation for it. If the site does support it, you can set the `Authorization` header Urlbox uses with the [`header`](https://urlbox.com/docs/options#header) option. If the site supports using a JWT for example, you normally use the `Bearer` scheme like this: ```bash curl -X POST \ https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer eb31005e820b40b2b34461a698b2b34d' \ -H 'Content-Type: application/json' \ -d ' { "url": "https://non-existent-authorization-header-demo.example.com", "full_page": true, "block_ads": true, "header": "Authorization=Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6IlRlc3QiLCJlbWFpbCI6ImRlbW8yQGV4YW1wbGUuY29tIiwiaWF0IjoxNzIxMTM4Mjk0LCJleHAiOjE3MjExMzkxOTR9.19ErlqIDiEtlh_Mbx5JGBNB2_KDFk84kfx8fBGKS0bA" } ' ``` If you're able to change what credentials the site accepts, I'd advise authorising Urlbox using a rotating temporary token in an `Authorization` header. If this isn't possible or you judge the risk of the token being leaked to be minimal, you can also use a static token. This approach is generally more secure than using a URL parameter as it's more likely to be treated as sensitive by your server (and so shouldn't be logged for example). As always, make sure you follow security best practices. ### Built in HTTP Authentication As mentioned earlier, there *is* a situation where browsers send an `Authorization` header in a webpage request and that's when a site uses built in HTTP Authentication. I couldn't find any stats on its use but it causes the browser itself to display a username and password popup which I rarely see. But if the site you want to screenshot uses it (or possibly supports it without telling the browser), here's how it works… There are two main schemes for built in HTTP Authentication: `Basic` and `Digest`, and since `Basic` is simpler and seems to be more popular, I'll focus on that. To authorise Urlbox, all we do is add an `Authorization` header with this format: ``` Basic <username>:<password> ``` Where the username, password and separating colon are [base64 encoded](https://developer.mozilla.org/en-US/docs/Web/API/btoa). :::note If you're wondering how this works in the browser, it's because I've skipped a stage here. Normally the user would first try to access a page without an `Authorization` header, resulting in a 401 and a `WWW-Authenticate` response header. This header contains at least one combination of a scheme name and its options (a challenge), which in this case is `Basic` and a `realm` option which describes to the user the part of the site they're signing into. Although the `realm` is now largely a historical artefact due to its phishing potential. Anyway, this challenge in the header results in the username and password prompt, which the browser uses to set the `Authorization` header on future requests. And since we can easily encode a username and password into an `Authorization` header ourselves, it's much easier to bypass this stage of the authorisation flow. ::: So if our username is `foo` and our password is `bar`, the `Authorization` header would be this without the base64 encoding: ``` Basic foo:bar ``` Then we base64 encode the `foo:bar` to get the final header value of: ``` Basic Zm9vOmJhcg== ``` Then we can have Urlbox include this header with its request like so: ```bash curl -X POST \ https://api.urlbox.com/v1/render/sync \ -H 'Authorization: Bearer eb31005e820b40b2b34461a698b2b34d' \ -H 'Content-Type: application/json' \ -d ' { "url": "https://httpbin.org/basic-auth/foo/bar", "full_page": true, "block_ads": true, "header": "Authorization=Basic Zm9vOmJhcg==" } ' ``` If you're interested, MDN has an article on the [other authentication schemes](https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication#authentication_schemes). ## Session Token Cookies Unfortunately for us in this case, most sites don't use the previous approaches for their authentication, except maybe on specific pages. This is to increase security and because supporting automatic tools like Urlbox isn't a priority. Instead, most sites use something a bit more custom where the user submits a login form to the server and it returns a session token as a cookie if the details are valid. The browser then sends the cookie with each request instead of the username and password. Here's a diagram to illustrate how it works with traditional random value session tokens, but the newer approach of JWTs is similar as fundamentally they are just a secret clients store and send instead of a username and password: ![Diagram where user sends POST request to server. If valid, server sends session ID as cookie as well as storing in database. Future requests from client contain the cookie. Server looks up session ID from cookie in database to verify their identity. If verified, server returns content for that user.](/content/screenshot-behind-login/session-diagram.png) Image credit: [AnuragT](https://commons.wikimedia.org/wiki/File:Cookies_Explainied.png) under CC BY-SA 3.0 Since the session token cookie is what actually authorises a request then, we can just log in manually, get its value and give it to Urlbox. This way we don't need to have Urlbox go through the login process or any other shenanigans. For some sites you might only need to copy one or two of their cookies but I'd recommend copying them all anyway to maximise the chances of this approach working. You *can* do this in DevTools and there's a section below explaining how to do this, but it's quite tedious. Instead, I'll use the open source extension [Cookie Editor](https://github.com/moustachauve/cookie-editor) for this guide and assume you're using Chrome. Once you've installed the extension, find it in `chrome://extensions/` and click on Details. ![Screenshot of the page with "cookie" in search bar](/content/screenshot-behind-login/find-extension.png) Then enable Allow in Incognito. ![Screenshot highlighting the Allow in Incognito option halfway through the options](/content/screenshot-behind-login/allow-incognito.png) Then open an Incognito tab and log into the site you want to take screenshots of. By using an Incognito tab, the browser will keep the storage separate to your normal tabs, allowing us to log into the site again. It also stops us from accidentally using Urlbox's session once we're done. Once you're logged in, click on the Cookie Editor extension, allow access if prompted, click Export then JSON. Next, create a .json file somewhere safe, paste what was copied to the clipboard and close the browser tab as it can cause our session to expire. ![Screenshot highlighting the leftmost button in the submenu opened from the button in the bottom right](/content/screenshot-behind-login/export-cookie-json.png) :::note **Warning**: Don't share the cookie files or values with anyone unless you want them to be able to access the account. ::: If you have a look at the file in a text editor, you'll see that each cookie is an object in a single array and each has a `name` and `value`. You should also see some other attributes that might need attention. Since only the names and values are sent to the site we're rendering, these other attributes generally don't matter too much. However, because Urlbox runs a browser and they *do* use these attributes, it's a good idea to handle them. Here's example of a file with one cookie: ```json [ { "domain": "localhost", "hostOnly": true, "httpOnly": false, "name": "sessionID", "path": "/", "sameSite": null, "secure": false, "session": true, "storeId": null, "value": "password" } ] ``` In order to set the cookies Urlbox sends with its requests, we can use the [`cookie`](https://urlbox.com/docs/options#cookie) option. But since that uses a different format (the same as the `Set-Cookie` response header) to a cookies.json file, we'll need some code to convert it. Download and extract [this starter](https://github.com/NicoClack-Experiments/Urlbox-Cookies-Starter), then run `npm install` in the directory. Have a look at the code to see how it works, then set the constants at the top of `index.js`. If you want to check if it's generating the cookie option correctly without sending a Urlbox request, leave `DEBUG_REQUEST` set to `true` and run. Once you're ready to take a screenshot, set `DEBUG_REQUEST` to `false` and run with `node index.js`. :::note **Troubleshooting**: If you're doing this in combination with a tunnel, you'll either need to use the tunnel when you originally capture the cookies or update the `domain` attributes to match the tunnel's domain. If you want to check what cookies are being received, you can change `SITE_URL` to an echo service like "[https://echo-http-requests.appspot.com/echo](https://echo-http-requests.appspot.com/echo)". Keep in mind that this is also a different domain to what your cookies use. I'd also advise replacing the sensitive cookie values before using the service. ::: :::note **Warning**: You should use environment variables instead of hardcoding secrets so you can share your code without leaking them. I'd suggest using [dotenv](https://www.npmjs.com/package/dotenv) for this and make sure to gitignore the `.env` file. ::: ### Caveats Unfortunately for us, some sites seem to have more advanced security that can cause some issues. In my testing, some sites displayed a login overlay (over the signed in content) or an entirely logged out view. Since logging in, clearing all of the site's storage and then restoring just the cookies worked in a local browser, I suspect some sort of fingerprinting is being used. Additionally, the session will usually expire after some time, especially since the `Set-Cookie` headers the site sends to Urlbox won't change the cookies used for future requests. If the headers are set by the site on the initial request, it isn't *too* complicated to store and reuse these cookie updates by fetching the initial HTML yourself before your Urlbox request. The [starter](https://github.com/NicoClack-Experiments/Urlbox-Cookies-Starter) has an example for this called `fetchWithPersistentCookies.js`. However, most sites will still log the user out eventually even if their browser is saving cookies correctly, so your mileage may vary. ### Manual Approach Using Chrome DevTools If you can't or don't want to install an extension, you can also get the cookies manually through Chrome DevTools, but it can be quite tedious. To do this, log into the site, press Shift + Ctrl/Command + J to open DevTools, go to the Application tab and expand the Cookies dropdown in the Storage section. Then go through the cookies for each origin (the example has all its cookies stored in the origin `http://localhost:8000`) and copy and paste the names, values and attributes you need. I'd suggest you store this data using the cookies.json template below so you can use the starter. ![Screenshot highlighting Application as the rightmost tab at the top. Localhost is highlighted in the Cookies dropdown on the left upper middle](/content/screenshot-behind-login/manual-devtools-save-cookies.png) Here's a cookie.json template. Copy and paste the object to add another cookie: ```json [ { "domain": "", "hostOnly": false, "httpOnly": false, "name": "", "path": "/", "sameSite": null, // If it's "None" in DevTools use "no_restriction" here "secure": false, "session": true, "storeId": null, "value": "" } ] ``` ## Conclusion There are a number of different ways to authorise Urlbox on a site. If it's your own site, use a temporary token in an `Authorization` header. If it's an existing site, specific pages might support using a token in a URL parameter, otherwise manually log in and clone your cookies. And some sites support the less secure Basic HTTP Authentication, making things even easier. --- # How to take screenshots of Social Media with Urlbox > Starting point options for screenshotting Instagram, X/Twitter, Facebook, and TikTok with the Urlbox Screenshot API. Source: https://urlbox.com/how-to-screenshot-social-media Last updated: 2026-02-25 --- :::note\[Quick Reference] | Platform | Needs POV? | Key Options | | --------- | ---------- | -------------------------------------------------------------------------- | | Instagram | Yes | `pov`, `min_size_bytes`, `retry_on`, `delay`, `scroll_delay`, `wait_until` | | X/Twitter | No | `min_size_bytes`, `retry_on`, `delay`, `scroll_delay`, `wait_until` | | Facebook | Yes | `pov`, `min_size_bytes`, `retry_on`, `delay`, `scroll_delay` | | TikTok | No | `min_size_bytes`, `retry_on`, `delay`, `scroll_delay` | Looking for a no-code solution? [CaptureDeck](https://capturedeck.com) lets you screenshot social media at scale without writing any code. ::: Social media platforms are notoriously challenging to screenshot programmatically. They use aggressive bot detection, dynamic JS loading, login walls, and constantly changing markup. Here we have put together some configurations that should give you a reasonable starting template. **Important:** These configurations work as of February 2026. Screenshotting social media platforms is a game of whack-a-turnstile. There are regular updates to bot detection methods, so you may need to tweak these over time, and we might do too. If something stops working, get in touch, and we will help you through it. ## Why Social Media Screenshots Are Tricky ![Instagram screenshot comparison - login wall on the left, successful capture on the right](/content/social-media-screenshot-presets/instagram-comparison.png) You've probably already discovered some of these issues: - **Bot detection**: Platforms like Instagram detect headless browsers and block aggressively, giving you bot detection turnstiles, captcha, or similar undesirable results when screenshotting. - **Dynamic content**: Infinite scroll, lazy loading, and client-side rendering can make screenshots look blank, not visually settled, or have missing page assets like images/videos. - **Login walls**: Some content requires authentication to view, so you get redirected to a login page or get obstructive modals popping up. The configurations below try to work around these issues using Point of View, delays, and retry logic. They are not bulletproof, but they work, and expose you to some useful options you may not have tried before. :::note\[Early Access Pricing] Point of View is a Urlbox feature that makes your requests appear as if from a regular user, helping bypass bot detection on platforms like Instagram and Facebook. The `pov` and `retry_on` options used in these examples are currently in early access. These features will incur significant additional costs once fully launched. Using `pov: "hidden"` will incur a 10x multiplier on the number of renders used by a request and is available from our [HiFi](https://urlbox.com/pricing) plan and above. Contact us for current pricing details. ::: ## How to Screenshot Instagram Instagram aggressively blocks datacenter IPs and headless browsers, so this configuration uses Point of View (`pov: "hidden"`) combined with delays, retry logic, and a minimum file size check to ensure you get real content rather than a login wall. Point of View makes your request appear as if from a regular doom-scroller rather than a datacenter. ```json { "url": "https://www.instagram.com/p/DUYpWx4jm0I/", "full_page": true, "pov": "hidden", "pov_country": "us", "user_agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/122.0.0.0 Safari/537.36", "delay": 4000, "wait_until": "mostrequestsfinished", "scroll_delay": 1000, "retry_on": "small_size,timeout,5xx,4xx", "max_retries": 3, "min_size_bytes": 1500000, "retry_delay_ms": 5000, "press_escape": true, "click_accept": true, "hide_cookie_banners": true } ``` **Some Context on the options used:** | Option | Description | | ---------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `pov: "hidden"` | Uses a Point of View to bypass bot detection. Makes your request appear as if from a regular doom-scroller! | | `pov_country: "us"` | Specifies which country to use for the Point of View. | | `delay: 4000` | Gives time for Javascript on the page to settle after requests finish | | `min_size_bytes: 1500000` | Checks the minimum file size to catch blank or error pages (\~1.5MB for Instagram) | | `retry_on: "small_size,timeout,5xx,4xx"` | Retries the render when it's smaller than `min_size_bytes`, the request times out, or returns an error | | `max_retries: 3` | Maximum number of retry attempts when retry\_on is applied. | | `retry_delay_ms: 5000` | The time to wait between retries in milliseconds when retry\_on is applied. | | `wait_until: "mostrequestsfinished"` | Allows page assets to load by waiting for most network requests to finish | | `scroll_delay: 1000` | When scrolling the page in steps, this delays each scroll to allow lazy-loaded content to appear | | `user_agent` | This tells our browser who to act as. It's often better to let us handle this, but if you're finding yourself blocked then mixing this up could help with bot fingerprinting | | `click_accept: true` | Accepts cookie consent banners | | `hide_cookie_banners: true` | Removes cookie and other bothersome banners using common heuristics | | `press_escape: true` | Presses the ESC key to help dismiss modals | For more information on the options used, consult our [docs](https://urlbox.com/docs/options) or contact us, and we'll do our best to help. ![Successful Instagram post screenshot](/content/social-media-screenshot-presets/instagram-success.png) ## How to Screenshot X (Twitter) X is more forgiving than Instagram - no Point of View needed for most public profiles and tweets. This configuration uses delays, `wait_until`, and retry logic to handle dynamic content loading. ```json { "url": "https://x.com/karpathy/status/1617979122625712128", "full_page": true, "user_agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/122.0.0.0 Safari/537.36", "wait_until": "mostrequestsfinished", "delay": 4000, "scroll_delay": 1000, "retry_on": "small_size,timeout,5xx,4xx", "retry_delay_ms": 5000, "max_retries": 3, "min_size_bytes": 10000, "press_escape": true, "click_accept": true, "hide_cookie_banners": true } ``` **Tip:** For individual tweets, consider using [Twitter's oEmbed](https://publish.x.com/) to get clean embed HTML, then screenshot that with Urlbox's HTML rendering mode. ![Successful X/Twitter post screenshot](/content/social-media-screenshot-presets/x-success.png) ## How to Screenshot Facebook Facebook requires Point of View (`pov: "hidden"`) for reliable results, combined with cookie banner handling to dismiss consent dialogs. Public pages and posts can usually be captured with this configuration. ```json { "url": "https://www.facebook.com/AnthropicAI/", "pov": "hidden", "full_page": true, "delay": 2000, "scroll_delay": 800, "retry_on": "small_size,timeout,5xx,4xx", "max_retries": 3, "retry_delay_ms": 2000, "min_size_bytes": 50000, "click_accept": true, "press_escape": true, "hide_cookie_banners": true } ``` ![Successful Facebook page screenshot](/content/social-media-screenshot-presets/facebook-success.png) ## How to Screenshot TikTok TikTok is surprisingly cooperative for public content and works without Point of View. This configuration uses delays, scroll handling, and retry logic to capture content reliably. ```json { "url": "https://www.tiktok.com/@theprimeagen/video/7251695355211926826", "full_page": true, "delay": 2000, "scroll_delay": 800, "retry_on": "small_size,timeout,5xx,4xx", "max_retries": 3, "min_size_bytes": 50000, "retry_delay_ms": 2000, "click_accept": true, "press_escape": true, "hide_cookie_banners": true } ``` ![Successful TikTok video screenshot](/content/social-media-screenshot-presets/tiktok-success.png) ## General Tips ### Use retries Social platforms can be flaky, they often don't load page assets, block requests, or redirect to login pages. Using `retry_on` and Setting `max_retries` to at least 3 helps catch transient failures: ```json { "max_retries": 3, "retry_on": "small_size,timeout,5xx,4xx", "retry_delay_ms": 5000 // time to wait before retrying, which helps with rate limit caused blocking } ``` Do also use `min_size_bytes`. Login and blank pages are typically much smaller than real content pages, and can sometimes be fixed by just trying again, so its always worth retrying if your screenshot is suspiciously small. **Note:** Using `retry_on` can significantly increase response times. Each retry adds the base render time plus `retry_delay_ms`, so a request with 3 retries and a 5 second delay could take considerably longer than a single render. For time-sensitive use cases, consider using [webhooks or the async endpoint](https://urlbox.com/docs/async-requests) for asynchronous delivery instead. ### Handle cookie banners These options help by clicking accept on cookie banners, finding and removing banners by common heuristics, and pressing the ESC key: ```json { "click_accept": true, "hide_cookie_banners": true, "press_escape": true } ``` ## Troubleshooting Common Errors ### Turnstiles and bot detection If you're seeing captchas, "prove you're human" challenges, or login walls, use `pov: "hidden"` to use Point of View. This makes your request appear as if from a regular user rather than a datacenter. ### Page assets not loading If your screenshots have blank images, missing content, or unsettled layouts, adjust your timing options: - Increase `delay` to give JavaScript more time to settle after requests finish - Increase `scroll_delay` to let lazy-loaded images appear as the page scrolls - Use `wait_until: "mostrequestsfinished"` or `requestsfinished` to wait for network requests to complete before capturing ## Limitations These configurations are designed for **public content**. Results may vary for: - Private accounts or posts - Age-restricted content - Content that requires login to view ## Getting Help If you're still having trouble after trying these configurations, contact us at [support@urlbox.com](mailto:support@urlbox.com) or click the chat button on our site.

Source: https://urlbox.com/website-screenshots-python Last updated: 2022-05-06 --- There are many reasons why developers might want to capture screenshots of web pages. You might want to capture an image generated from dynamic code that you've written, collect screenshots of web pages mentioned in a dataset that you're working with, or keep software documentation up to date by automating screenshots using a CI/CD tool. It can be surprisingly tricky to take screenshots using Python, especially when JavaScript is involved. In this tutorial, you’ll learn to take screenshots of web pages using different approaches and packages in Python. You'll also see how a tailor-made solution like Urlbox can help you to easily capture screenshots of websites. ## Taking Screenshots With Python To follow along with this tutorial, you’ll need to have [Python 3](https://www.python.org/downloads/) installed. This tutorial uses Python v3.9.12. All of the code used in this tutorial is available in this [GitHub repository](https://github.com/ravgeetdhillon/python-web-screenshots). ### Setting Up the Project Open up your terminal, navigate to a path of your choice, and run the following commands to create the project’s directory: ```bash mkdir python-web-screenshots cd python-web-screenshots ``` Create a virtual environment for the Python project by running the following command in your terminal: ```bash python3 -m venv venv ``` Activate the virtual environment by running the following command in your terminal: ```bash source venv/bin/activate ``` That’s it—the project directory is set up and ready to go. Next, you’ll learn to take screenshots of web pages using different Python packages. ### Using Selenium Install [Selenium](https://www.selenium.dev/) and a [web driver manager](https://pypi.org/project/webdriver-manager/) by running the following command in your terminal: ```bash pip install selenium webdriver-manager ``` Create a `main.py` file and add the following code to it: ```python # 1 from selenium import webdriver from webdriver_manager.chrome import ChromeDriverManager # 2 driver = webdriver.Chrome(ChromeDriverManager().install()) # 3 driver.get('https://urlbox.com') # 4 driver.save_screenshot('screenshot.png') # 5 driver.quit() ``` The steps in the above code do the following: - **One:** Imports the required packages. For this tutorial, you'll import the Chrome driver (`ChromeDriverManager`), but you can use the [driver of your choice](https://pypi.org/project/webdriver-manager/). - **Two:** Creates a driver instance (`driver`) for the Chrome web browser. - **Three:** Fetches (`driver.get`) the page specified in the URL so you can take a screenshot of it. - **Four:** Saves the fetched response as the screenshot (`driver.save_screenshot`). - **Five:** Closes (`driver.quit`) the driver and exits the program. You can execute the Python script above by running the following command in your terminal: ```bash python main.py ``` Here’s what a screenshot of a blog looks like with this method: ![Selenium GUI screenshot](/content/using-python-scripts-to-take-screenshots/5WAiN0F.png) You can see that the screenshot was taken while the page was still loading—the empty space on the right side is supposed to contain a block of content. You can go to the [original page](https://www.geeksforgeeks.org/why-reading-code-is-more-important-than-writing/) to see for yourself what it should have looked like. In addition to the possibility that the screenshot will be captured before the website is ready, you need to manually configure the width and height of the screenshot window to capture the full window. In most cases, this will result in odd scroll bars in screenshots taken with this method. Also, the cookies banner at the bottom of the page is blocking some content. #### Using Selenium Headlessly The approach above is only possible when you have access to a GUI. In some cases, like when you're using CI/CD tools, that approach won't work. To get around this limitation, you can use the [headless](https://en.wikipedia.org/wiki/Headless_software) approach to take screenshots of websites. To do so, update the `main.py` file by adding the following code to it: ```python # 1 from selenium import webdriver from selenium.webdriver.chrome.options import Options from webdriver_manager.chrome import ChromeDriverManager # 2 options = Options() options.headless = True # 3 driver = webdriver.Chrome(ChromeDriverManager().install(), options=options) # 4 driver.get('https://urlbox.com') driver.save_screenshot('screenshot.png') # 5 driver.quit() ``` Again, looking at the code step by step, it does the following: - **One:** Imports the required packages. - **Two:** Creates an `Options` instance and set the `headless` parameter to `True`. - **Three:** Creates a driver instance (`driver`) for the Chrome Web browser. - \*Four:\*\* Fetches (`driver.get`) the webpage you want to take the screenshot off of by providing its URL and save the fetched response as the screenshot (`driver.save_screenshot`). - **Five:** Closes (`driver.quit`) the driver and exits the program. Execute the above Python script by running the following command in your terminal: ```bash python main.py ``` Here’s how a screenshot of the same page from earlier looks: ![Selenium headless screenshot](/content/using-python-scripts-to-take-screenshots/0hbUgGf.png) This method automatically captured the webpage in mobile view, and doesn't do anything about the cookies banner at the bottom. However, it doesn't require spinning up a Chromium instance just for taking screenshots, and the result is better than the previous method. ### Using IMGKit [IMGKit](https://pypi.org/project/imgkit/) is a Python wrapper for the [wkhtmltoimage](https://wkhtmltopdf.org/) utility, which is used to convert HTML to IMG using Webkit. Install IMGKit and wkhtmltoimage by running the following commands in your terminal: ```bash pip install imgkit brew install wkhtmltoimage ``` Update the `main.py` file by adding the following code to it: ```python # 1 import imgkit # 2 imgkit.from_url('https://youtube.com', 'youtube.png') ``` In the above code: - **One:** Imports the `imgkit` package. - **Two:** Downloads the specified URL, and saves the images using the `from_url` method from `imgkit`. Execute the above Python script by running the following command in your terminal: ```bash python main.py ``` Here’s what a screenshot taken using this method looks like: ![IMGKit screenshot](/content/using-python-scripts-to-take-screenshots/IDVYURj.jpg) This method takes a full-page screenshot of the blog by default, though for simplicity, only the top part of it is shown here. This method was clearly unable to render the header and other elements at the top of the page nicely. There's also no official support for installing the wkhtmltoimage package on Apple Silicon Macs, which means you need to resort to workarounds such as using Rosetta or installing wkhtmltopdf, which installs wkhtmltoimage internally. ### Using Shot-Scraper [Shot-scraper](https://github.com/simonw/shot-scraper) is a Python-based CLI tool built by Simon Willison. It allows you to take screenshots of the viewable portion of a page, full-page screenshots, and screenshots of specific sections. To work with it, begin by installing [shot-scraper](https://pypi.org/project/shot-scraper/) by running the following command in your terminal: ```bash pip install shot-scraper ``` Shot-scraper is built on [Playwright](https://playwright.dev/), you'll also need to install Playwright by running the following command in your terminal: ```bash shot-scraper install ``` To take a screenshot of a website, run the following command in your terminal: ```bash shot-scraper <URL> ``` You can also take advantage of CSS selectors to take screenshots of particular sections of a website by running the following command in your terminal: ```bash shot-scraper https://simonwillison.net/ -s '#<SELECTOR-NAME>' ``` This will take a screenshot of the designated element. Here’s what the screenshot looks like: ![shot-scraper screenshot](/content/using-python-scripts-to-take-screenshots/pXRjTOC.jpg) So far, this has been the best screenshot we’ve seen out of the box. It defaults to a full-page layout, but still fails to account for the cookies banner, and the content block on the top right is still empty. Let’s see how Urlbox fixes this. ### Using Urlbox [Urlbox](https://urlbox.com/.md) is a screenshot API that allows you to take screenshots of webpages without having to write a single line of JavaScript. It allows you to block pop-ups, ads, and other interstitial elements that would detract from your screenshots. You're able to select specific elements to capture, block elements, take high-definition screenshots, emulate a dark mode, specify a user agent, and many other options with ease. It also offers a user-friendly GUI where you can preview all of the API options. To get started with Urlbox, visit [Urlbox](https://urlbox.com/.md) and create a free new account. When sign-up is complete, you’ll be given your API key and API secret, which will allow you to access Urlbox’s service: ![API key and secret](/content/using-python-scripts-to-take-screenshots/LBIfZdh.png) Create a `.env` file at the root of your project, next to the `main.py` file, and add the `API_KEY` and `API_SECRET` as environment variables to it: ``` API_KEY=<your-api-key> API_SECRET=<your-api-secret> ``` Install the [Urlbox](https://pypi.org/project/urlbox/) and [python-dotenv](https://pypi.org/project/python-dotenv/) packages by running the following command in your terminal: ```bash pip install urlbox python-dotenv ``` Update the `main.py` file by adding the following code to it: ```python # 1 from urlbox import UrlboxClient from dotenv import load_dotenv import os # 2 load_dotenv() API_KEY = os.getenv('API_KEY') API_SECRET = os.getenv('API_SECRET') # 3 urlbox_client = UrlboxClient(api_key=API_KEY, api_secret=API_SECRET) # 4 response = urlbox_client.get({ "url": "<URL>" }) # 5 with open("screenshot.png", "wb") as f: f.write(response.content) ``` In the above code: - **One:** Imports the required packages: `urlbox`, `dotenv`, and `os`. - **Two:** Reads the `API_KEY` and `API_SECRET` environment variables. - **Three:** Creates an Urlbox client instance (`urlbox_client`) and provides it with the `API_KEY` and `API_SECRET`. - **Four:** Fetches the webpage (`urlbox_client.get`) you want to take the screenshot of from the provided URL (`url`). - **Five:** Saves the fetched response as a screenshot. Execute the above Python script by running the following command in your terminal: ```bash python main.py ``` Here’s what the screenshot looks like: ![Urlbox basic screenshot](/content/using-python-scripts-to-take-screenshots/xxNKqox.png) Without tweaking any options, you can see that all of the content visible at the top of the page is visible, including the content block on the right. Now let’s take it up a notch by going for a full page screenshot with a set width: ```python response = urlbox_client.get({ "url": "https://urlbox.com/", "full_page": True, "width": 1200 }) ``` Here’s how it looks now: ![Urlbox full page screenshot](/content/using-python-scripts-to-take-screenshots/Cgj4VPG.png) The image above is a cropped version of the full-length screenshot of the page. You can see that since this is a full-page screenshot, the cookies banner and other elements that are supposed to be anchored at the bottom of the view frame aren't dangling in the middle of the screenshot. Also, the page has been loaded completely and all sections are clearly visible. There are a multitude of other options available to help you maintain full control over the final appearance of your screenshots. For instance, you can block advertisements with `block_ads`, or hide cookie banners with `hide_cookie_banners`. You can also specify the image formats in which to save screenshots with the `format` option. You can implement all of those as follows: ```python response = urlbox_client.get({ "url": "https://urlbox.com/", "format": "jpg", "full_page": False, "hide_cookie_banners": True, "block_ads": True }) ``` Here’s how the screenshot looks now: ![Urlbox no ads/banner screenshot](/content/using-python-scripts-to-take-screenshots/b5xMLtJ.jpg) This is not a full-page screenshot, but with the use of `hide_cookie_banners` and `block_ads` options, the cookie ribbon from the bottom and the ad block on the right of the page have been automatically removed! These are just a handful of the features that Urlbox offers. You can read more about the [available options](https://urlbox.com/docs/options.md). Urlbox also allows you to take screenshots and preview the effect of all options through the Urlbox dashboard. ![Urlbox dashboard](/content/using-python-scripts-to-take-screenshots/6c2qAkg.png) ## Conclusion In this tutorial, you learned to take screenshots of web pages using several different approaches and packages in Python. You also saw how [Urlbox](https://urlbox.com/.md) can give you more control over the final appearance of your image, while also providing you with an easier, more robust way to capture screenshots of your web applications. --- # Capturing a Screenshot of a Webpage in ASP.NET Core > This article will show you how to take screenshots of webpages in an ASP.NET Core application without JavaScript. Source: https://urlbox.com/website-screenshots-aspnetcore Last updated: 2025-02-06 --- There are many reasons you, as a developer, might want to screenshot a webpage. For example, you may want to take regular screenshots of a website for monitoring or compliance purposes, generate images from dynamic HTML, CSS, and SVG, or create image previews of URLs for social media or your own directory of links. When you deal with webpage screenshots, it's common to think you need to use JavaScript to interact with a web page to screenshot it. For example, you might think of writing a Node.js service that will accept REST requests for screenshots, process them, and return the screenshot. Granted, this is a possible solution, but it isn't straightforward! This article will show you how to take screenshots of webpages in an ASP.NET Core application without JavaScript. First, you'll set up a Reading List Web API. Then, you'll see how you can use different NuGet packages to take screenshots of webpages from an ASP.NET Core application. You'll also learn to use the [Urlbox library](https://github.com/urlbox-io/urlbox-dotnet) to take screenshots asynchronously. ## Prerequisites The code samples in this article are compatible with .NET 6. .NET 6 is the latest LTS version of .NET from Microsoft, which lets you write performant, cross-platform applications using a single codebase. Please download the [.NET 6 SDK](https://dotnet.microsoft.com/en-us/download/dotnet/6.0) to follow along with the code samples. Many code samples use [Google Chrome](https://www.google.com/chrome/) to render and screenshot the web pages. While most libraries automatically download Chrome, it's best to manually install it before starting so that you have all the necessary dependencies to run the browser from code. This tutorial also requires [PowerShell 7.2](https://docs.microsoft.com/en-us/powershell/scripting/overview?view=powershell-7.2) for some of the NuGet package setup scripts. PowerShell is a cross-platform task automation solution developed by Microsoft. You can download the latest version of PowerShell for your platform [here](https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell?view=powershell-7.2). You can find all the completed projects from this tutorial in [this GitHub repository](https://github.com/ivankahl/UrlboxDotnetDemoProjects). ## Setting Up the Project To demonstrate taking screenshots in an ASP.NET Core application, you'll build a basic Reading List Web API. The API will let you save and retrieve URLs in your reading list. You'll also see how you can take screenshots of those URLs for link previews on your user interface. You can download the starter code from this [GitHub repository](https://github.com/ivankahl/UrlboxDotnetStarterProject) if you want to skip to taking screenshots in ASP.NET Core. ### Create the Project Open a new terminal window and navigate to the folder where you want to store your code. Next, run the following command to create a new ASP.NET Core Web API using the .NET CLI. ```bash dotnet new webapi -o ReadingListApi ``` ### Write the IScreenshotService Interface Interfaces make it easy to describe method headers without implementing them. You'll write an IScreenshotService interface to define the methods available to screenshot a web page. This interface will make it easy to update the application to use the different screenshot service implementations presented in this article. Create a **Services** folder in the project directory. Then, create a **Screenshot** subdirectory in that folder. Next, create the file `IScreenshotService.cs` and paste in the code below: **IScreenshotService.cs** ```csharp namespace ReadingListApi.Services.Screenshot { public interface IScreenshotService { Task<byte[]> ScreenshotUrlAsync(string url); } } ``` ### Create the IReadingListService Interface and Implement It It's best practice to keep controller methods lightweight. To do this, you'll implement the Reading List API's logic in a service. In the **Services** folder, create a **ReadingList** folder. Next, you'll make the model classes and service interface and class. Create **Models** and **DTO** (Data Transfer Object) folders inside the **ReadingList** folder. Inside the **Models** folder, create a `ReadingItemModel` class, which will store the URL in the database. Create the file `ReadingItemModel.cs` with the following content: ```csharp namespace ReadingListApi.Services.ReadingList.Models { public class ReadingItemModel { public Guid Id { get; set; } public string Title { get; set; } public DateTime Reminder { get; set; } public string Url { get; set; } public bool ScreenshotTaken { get; set; } } } ``` Next, you'll create data transfer objects that you'll use for requests and responses in the REST API. First, create a `ReadingItemDTO.cs` file in the **DTO** folder. This DTO will return the details for an item in the database. Then, copy the following code into the new file named `ReadingItemDTO.cs`: ```csharp namespace ReadingListApi.Services.ReadingList.DTO { public class ReadingItemDTO { public Guid Id { get; set; } public string Title { get; set; } public DateTime Reminder { get; set; } public string Url { get; set; } public bool ScreenshotTaken { get; set; } } } ``` Make a new file in the **DTO** folder and call it `ReadingItemCreateDTO.cs`. This DTO will be the request object for creating a new item in the database. You can paste the following code into the file: ```csharp namespace ReadingListApi.Services.ReadingList.DTO { public class ReadingItemCreateDTO { public string Title { get; set; } public DateTime Reminder { get; set; } public string Url { get; set; } } } ``` Once you've created the necessary model and DTO objects, you'll need to write the service interface and implement it. To do this, create the file `IReadingListService.cs` in the **ReadingList** folder and copy the following code into it: ```csharp using ReadingListApi.Services.ReadingList.DTO; namespace ReadingListApi.Services.ReadingList { public interface IReadingListService { Task<Guid> CreateReadingItemAsync(ReadingItemCreateDTO readingItem); Task<byte[]?> GetReadingItemScreenshotAsync(Guid id); Task<IEnumerable<ReadingItemDTO>> ListReadingItemsAsync(); } } ``` Once you've created the interface, implement it by creating a `ReadingListService.cs` file and copying the following class code into it: ```csharp using ReadingListApi.Services.ReadingList.DTO; using ReadingListApi.Services.ReadingList.Models; using ReadingListApi.Services.Screenshot; namespace ReadingListApi.Services.ReadingList { public class ReadingListService : IReadingListService { private readonly List<ReadingItemModel> _readingItems = new(); private readonly IScreenshotService _screenshotService; private readonly IConfiguration _configuration; public ReadingListService(IScreenshotService screenshotService, IConfiguration configuration) { _screenshotService = screenshotService; _configuration = configuration; } public async Task<Guid> CreateReadingItemAsync(ReadingItemCreateDTO readingItem) { // Create a new model for the reading item var model = new ReadingItemModel() { Id = Guid.NewGuid(), Reminder = readingItem.Reminder, Title = readingItem.Title, Url = readingItem.Url }; // Determine where to save the screenshot var fileName = $"{model.Id}.png"; var fullFilePath = Path.Combine(_configuration["ScreenshotsFolder"], fileName); // Take the screenshot var screenshotBytes = await _screenshotService.ScreenshotUrlAsync(readingItem.Url); await File.WriteAllBytesAsync(fullFilePath, screenshotBytes); // Update our model with the file name model.ScreenshotTaken = true; // Add the model to our "database" _readingItems.Add(model); return model.Id; } public async Task<byte[]?> GetReadingItemScreenshotAsync(Guid id) { // Try to get the item from the database var item = _readingItems.FirstOrDefault(x => x.Id == id); // Make sure we have selected a reading item record and that // a screenshot was taken. If no item was found or the screenshot // has not been taken, return null. if (item == null || item.ScreenshotTaken == false) return null; // Retrieve the screenshot and return it as a byte array. var fullFilePath = Path.Combine(_configuration["ScreenshotsFolder"], $"{item.Id}.png"); return await File.ReadAllBytesAsync(fullFilePath); } public Task<IEnumerable<ReadingItemDTO>> ListReadingItemsAsync() { // Return all the reading items in the database return Task.FromResult(_readingItems.Select(x => new ReadingItemDTO() { Id = x.Id, Reminder = x.Reminder, Title = x.Title, Url = x.Url, ScreenshotTaken = x.ScreenshotTaken })); } } } ``` Finally, register the ReadingListService implementation in the `Program.cs` file by adding this line after creating the `builder` variable. Further down in the same file, add code to create the screenshots folder if it doesn't already exist: ```csharp // ... // Using our reading list service using ReadingListApi.Services.ReadingList; var builder = WebApplication.CreateBuilder(args); // Add services to the container builder.Services.AddSingleton<IReadingListService, ReadingListService>(); // ... app.UseHttpsRedirection(); Directory.CreateDirectory(app.Configuration["ScreenshotsFolder"]); // ... ``` Make sure you configure the ScreenshotsFolder in the `appsettings.json` file: ```json { // .. "ScreenshotsFolder": "<PATH TO SCREENSHOTS DIRECTORY>" } ``` ### Set Up the ReadingListController The last scaffolding step is to set up the `ReadingListController` class. This class will expose the actual endpoints in the REST API. In the **Controllers** folder, create a `ReadingListController.cs` file and paste in the following code: ```csharp using Microsoft.AspNetCore.Mvc; using ReadingListApi.Services.ReadingList; using ReadingListApi.Services.ReadingList.DTO; namespace ReadingListApi.Controllers { [ApiController] [Route("[controller]")] public class ReadingListController : ControllerBase { private readonly ILogger<ReadingListController> _logger; private readonly IReadingListService _readingListService; public ReadingListController(ILogger<ReadingListController> logger, IReadingListService readingListService) { _logger = logger; _readingListService = readingListService; } [HttpPost] public async Task<IActionResult> CreateReadingItemAsync(ReadingItemCreateDTO readingItem) { try { return Ok(await _readingListService.CreateReadingItemAsync(readingItem)); } catch (Exception ex) { _logger.LogError("An error occurred while creating a reading item: {Exception}", new { Exception = ex }); return StatusCode(StatusCodes.Status500InternalServerError, "An error occurred while creating a reading item"); } } [HttpGet] public async Task<IActionResult> ListReadingItemsAsync() { try { return Ok(await _readingListService.ListReadingItemsAsync()); } catch (Exception ex) { _logger.LogError("An error occurred while listing all the reading items: {Exception}", new { Exception = ex }); return StatusCode(StatusCodes.Status500InternalServerError, "An error occurred while listing all the reading items"); } } [HttpGet("{id}/screenshot")] public async Task<IActionResult> GetScreenshotAsync(Guid id) { try { var file = await _readingListService.GetReadingItemScreenshotAsync(id); if (file == null) return NotFound(); return File(file, "image/png"); } catch (Exception ex) { _logger.LogError("An error occurred while retrieving the screenshot file: {Exception}", new { Exception = ex }); return StatusCode(StatusCodes.Status500InternalServerError, "An error occurred while retrieving the screenshot file"); } } } } ``` Ensure that your controllers are registered in your program.cs by calling the builder service: ```csharp // Ensure this method is called builder.Services.AddControllers(); builder.Services.AddEndpointsApiExplorer(); builder.Services.AddSwaggerGen(); var app = builder.Build(); ``` Also ensure that your controllers are mapped before running the app: ```csharp Directory.CreateDirectory(app.Configuration["ScreenshotsFolder"]); // Ensure this method is called app.MapControllers(); app.Run(); ``` You are now ready to start implementing screenshot functionality in your application. ## Using PuppeteerSharp The [PuppeteerSharp](https://www.puppeteersharp.com/) [NuGet package](https://www.nuget.org/packages/PuppeteerSharp) is a .NET port of the popular Node.js Puppeteer API. The package lets you use Google Chrome programmatically for various automation tasks, such as taking screenshots. With a terminal open in the project folder, run the following command to install the package: ```bash dotnet add package PuppeteerSharp --version 7.1.0 ``` You'll now implement the IScreenshotService interface using the PuppeteerSharp package. First, create a file called `PuppeteerSharpScreenshotService.cs` in the **Services > Screenshot** folder. Then, copy and paste the following code into the file: ```csharp using PuppeteerSharp; namespace ReadingListApi.Services.Screenshot { public class PuppeteerSharpScreenshotService : IScreenshotService { public async Task<byte[]> ScreenshotUrlAsync(string url) { // First download the browser (this will only happen once) await DownloadBrowserAsync(); // Start a new instance of Google Chrome in headless mode var browser = await Puppeteer.LaunchAsync(new LaunchOptions() { Headless = true, DefaultViewport = new ViewPortOptions() { Width = 1920, Height = 1080 } }); // Create a new tab/page in the browser and navigate to the URL var page = await browser.NewPageAsync(); await page.GoToAsync(url); // Screenshot the page and return the byte stream var bytes = await page.ScreenshotDataAsync(); await browser.CloseAsync(); return bytes; } private async Task DownloadBrowserAsync() { using var browserFetcher = new BrowserFetcher(); await browserFetcher.DownloadAsync(BrowserFetcher.DefaultChromiumRevision); } } } ``` The method above first downloads Google Chrome if it hasn't already been downloaded. It then creates a new browser instance with some launch options. Once the browser runs, the method creates a new page and navigates to the specified URL; when the page has loaded, the code takes a screenshot and closes the browser. Finally, the method returns the screenshot's raw bytes. In the `Program.cs` file, register the PuppeteerSharpScreenshotService class so you can use it in the ReadingListService. Do this by adding the following line before the line that registers the `ReadingListService` class: ```csharp // ... var builder = WebApplication.CreateBuilder(args); // Add services to the container. builder.Services.AddSingleton<IScreenshotService, PuppeteerSharpScreenshotService>(); builder.Services.AddSingleton<IReadingListService, ReadingListService>(); // ... ``` Start the application by running the following command in the terminal: ```bash dotnet run ``` You can now run a POST request to `/ReadingList`. What we want to extract is the Unique ID (UUID) from the response, as we'll need that in the next step. After running a request to the below endpoint, you should see a screenshot saved in the folder you setup in your `appsettings.json`. Here's a basic curl request (change the port as needed) or you can run this in Postman: ```bash curl --location 'http://localhost:5021/ReadingList' \ --header 'Content-Type: application/json' \ --data '{ "title": "TechCrunch", "reminder": "2025-02-05T19:00:00.000Z", "url": "https://www.techcrunch.com/" }' ``` To Use swagger, open the Swagger page in a browser by going to `https://localhost:<PORT>/swagger/index.html`. Add a new URL to your reading list on the Swagger page using the `POST /ReadingList` endpoint. The endpoint will save the object to the database, take a screenshot of the URL, and return the ID of the new reading item in the response. ![Use the POST /ReadingList endpoint to add a new URL to your reading list](/content/website-screenshots-aspnetcore/CvcSwCA.png) Copy the ID from the response object and use it in the `GET /ReadingList/{id}/screenshot` endpoint. This endpoint will retrieve the screenshot for the saved URL. ![Use the GET /ReadingList/url/screenshot endpoint to retrieve the screenshot for the reading item](/content/website-screenshots-aspnetcore/GI1x5Mi.png) Below is a screenshot of the TechCrunch homepage taken with PuppeteerSharp: ![The screenshot PuppeteerSharp took of the TechCrunch homepage](/content/website-screenshots-aspnetcore/3c9dcf71-71e5-481f-b1ff-05ebc7140828.png) The screenshot is appropriately sized and portrays the web page accurately. However, one immediate eyesore is the advertisements on the page's top. There is also a banner at the bottom of the web page, which looks unappealing. ## Using Selenium [Selenium](https://www.selenium.dev/) is a browser automation tool similar to PuppeteerSharp. However, unlike PuppeteerSharp, Selenium is compatible with several browser vendors, meaning you're not limited to using Chromium-based browsers. The [Selenium WebDriver API](https://www.selenium.dev/documentation/webdriver/) enables the library to communicate with different browsers. Run the following commands in the terminal. The first command installs the [Selenium NuGet package](https://www.nuget.org/packages/Selenium.WebDriver). The second command installs a [NuGet package](https://www.nuget.org/packages/WebDriverManager) that will assist in downloading the correct WebDriver to use with Chrome: ```bash dotnet add package Selenium.WebDriver dotnet add package WebDriverManager ``` Once you've installed the packages, create another class called `SeleniumScreenshotService` in the **Services > Screenshot** directory, and paste in the following code: ```csharp using OpenQA.Selenium.Chrome; using OpenQA.Selenium; using WebDriverManager; using WebDriverManager.DriverConfigs.Impl; using System.Drawing; namespace ReadingListApi.Services.Screenshot { public class SeleniumScreenshotService : IScreenshotService { public Task<byte[]> ScreenshotUrlAsync(string url) { // We need to download the correct driver for Chrome new DriverManager().SetUpDriver(new ChromeConfig()); var options = new ChromeOptions(); options.AddArgument("headless"); // Use the driver to start a new instance of Google // Chrome var driver = new ChromeDriver(options); // Set the window size appropriately driver.Manage().Window.Size = new Size(1920, 1080); // Navigate to the specified URL driver.Navigate().GoToUrl(url); // Take a screenshot of the web page and return the // image's raw bytes var screenshot = (driver as ITakesScreenshot).GetScreenshot(); var bytes = screenshot.AsByteArray; driver.Close(); driver.Quit(); return Task.FromResult(bytes); } } } ``` The code first downloads the correct WebDriver for Chrome using the WebDriverManager package. It then creates a new window in Chrome and navigates to the specified URL. Once the website has loaded, the method takes a screenshot and receives the image's raw bytes. Finally, the browser is closed, and the raw bytes are returned. In the `Program.cs` file, replace the line that registered the PuppeteerSharpScreenshotService with the following: ```csharp // ... var builder = WebApplication.CreateBuilder(args); // Add services to the container. builder.Services.AddSingleton<IScreenshotService, SeleniumScreenshotService>(); builder.Services.AddSingleton<IReadingListService, ReadingListService>(); // ... ``` Rerun the application using the following command: ```bash dotnet run ``` Navigate to the Swagger page and follow the same process as before to save a new URL to the reading list and retrieve its screenshot. You should see an image similar to the one below if you saved the TechCrunch homepage: ![The screenshot Selenium took of the TechCrunch homepage](/content/website-screenshots-aspnetcore/3c9dcf71-71e5-481f-b1ff-05ebc7140828.png) The screenshot looks remarkably similar to the one taken with PuppeteerSharp. You'll notice that advertisements are still appearing on the page. The ugly bottom banner is also still visible. ## Using Playwright [Playwright](https://playwright.dev/dotnet/) is a modern browser automation library developed by Microsoft. While it's designed primarily for end-to-end testing of web apps, you can also use it for browser automation tasks. Like Selenium, it supports multiple browser vendors with a single API. In the terminal, run the following command to install the [Playwright NuGet package](https://www.nuget.org/packages/Microsoft.Playwright): ```bash dotnet add package Microsoft.Playwright ``` After adding the package to the project, Playwright must complete its setup with a PowerShell script. To do this, build the project. Once built, run the PowerShell script and wait for it to finish: ```bash dotnet build pwsh bin\Debug\net6.0\playwright.ps1 install ``` In the **Services > Screenshot** folder, create a file called `PlaywrightScreenshotService.cs` and paste the following code in there: ```csharp using Microsoft.Playwright; namespace ReadingListApi.Services.Screenshot { public class PlaywrightScreenshotService : IScreenshotService { public async Task<byte[]> ScreenshotUrlAsync(string url) { // Create a new instance of Playwright using var playwright = await Playwright.CreateAsync(); // Open a new instance of the Google Chrome browser in headless mode await using var browser = await playwright.Chromium.LaunchAsync(new() { Headless = true }); // Create a new page in the browser var page = await browser.NewPageAsync(new() { ViewportSize = new() { Width = 1920, Height = 1080 } }); await page.GotoAsync(url); // Screenshot the page and return the raw bytes return await page.ScreenshotAsync(); } } } ``` The Playwright implementation is the most straightforward code so far! The code first instantiates a new instance of Playwright. Next, the Playwright instance launches Chrome. Once the browser runs, a new page is created with the desired viewport dimensions and used to navigate to the specified URL. Finally, the method takes a screenshot and returns the raw bytes. Update the `Program.cs` file to use the PlaywrightScreenshotService implementation of the IScreenshotService interface: ```csharp // ... var builder = WebApplication.CreateBuilder(args); // Add services to the container. builder.Services.AddSingleton<IScreenshotService, PlaywrightScreenshotService>(); builder.Services.AddSingleton<IReadingListService, ReadingListService>(); // ... ``` Rerun the application: ```bash dotnet run ``` Open Swagger and use the REST endpoints to save a URL and retrieve its screenshot. Below is an example of a screenshot of the TechCrunch homepage taken with Playwright. ![The TechCrunch homepage screenshotted using Playwright](/content/website-screenshots-aspnetcore/3c9dcf71-71e5-481f-b1ff-05ebc7140828.png) Once again, the screenshot looks similar to the previous screenshots. The advertisements are still visible and the banner on the bottom also still blocks portions of the page. While this is easier to implement, the final screenshot has the same flaws as the previous screenshots. ## Using Urlbox [Urlbox](https://urlbox.com/.md) is a service that specializes in taking web page screenshots. The service exposes a REST API that's simple yet incredibly flexible. Their service offering includes advanced functionality such as [retina screenshots](https://urlbox.com/docs/options.md#retina), [web font](https://urlbox.com/webfonts.md), and [emoji support](https://urlbox.com/emoji.md), SVG support, [ad blocking](https://urlbox.com/docs/options.md#block_ads), and [webhooks](https://urlbox.com/docs/webhooks.md). They offer a [seven-day free trial](https://urlbox.com/pricing.md) to try all their features, after which you can upgrade to one of their [paid plans](https://urlbox.com/pricing.md). Sign up for a [seven-day free trial](https://urlbox.com/pricing.md). You can log in after confirming your email address. When you log in, you'll be taken to the Dashboard page, where you'll find your API Key and Secret. You'll need these later, so be sure to take note of them. To interact with Urlbox, we can utilise the Urlbox .NET SDK. The Nuget page is [here](https://www.nuget.org/packages/Urlbox.sdk.dotnet). Add the SDK to your project: ```bash dotnet add package Urlbox.sdk.dotnet --version 2.0.1 ``` You'll now want to create a screenshot service implementation that uses Urlbox. To do this, create a `UrlboxScreenshotService.cs` file in the **Services > Screenshot** folder and paste in the following code: ```csharp using UrlboxSDK; using UrlboxSDK.Options.Resource; namespace ReadingListApi.Services.Screenshot { public class UrlboxScreenshotService : IScreenshotService { private readonly IUrlbox _urlbox; public UrlboxScreenshotService(IUrlbox urlbox) { _urlbox = urlbox; } public async Task<byte[]> ScreenshotUrlAsync(string url) { UrlboxOptions options = Urlbox.Options(url) .Format(Format.Png) .Width(1920) .Height(1080) .BlockAds() .HideCookieBanners() .Retina() .ClickAccept() .HideSelector(".pn-ribbon") .Build(); string image = await _urlbox.DownloadAsBase64(options); // The default Base64 string includes the content type // which .NET doesn't want // e.g. image/png;base64,XXXXXXXXXXXXXXX image = image.Substring(image.IndexOf(",") + 1); return Convert.FromBase64String(image); } } } ``` The SDK uses the fluent builder pattern to make it easier to configure your options, where calling `.Build()` builds the final options object. Feel free to update this with any of the options the SDK provides. You can read more about these in the readme of the [GitHub repository](https://github.com/urlbox/urlbox-dotnet). Update the `Program.cs` file to register the UrlboxScreenshotService. ```csharp // ... var builder = WebApplication.CreateBuilder(args); // Add Urlbox to the DI container builder.Services.AddUrlbox(options => { options.Key = "YOUR_PUBLISHABLE_API_KEY"; options.Secret = "YOUR_SECRET"; // options.WebhookSecret = "your-webhook-secret"; // Optional }); builder.Services.AddSingleton<IScreenshotService, UrlboxScreenshotService>(); builder.Services.AddSingleton<IReadingListService, ReadingListService>(); // ... ``` Make sure to replace the placeholders with your publishable API key and secret, and optionally the webhook secret. `.AddUrlbox()` allows you to define how your Urlbox instance is created in one place across your whole app. We highly recommend you don't hardcode your API keys, and instead use environment variables. Lastly, run the application: ```bash dotnet run ``` Use the Postman Collection or Open Swagger in your browser and save a URL. Then, retrieve the screenshot and see the result. To demonstrate, if you took a screenshot of the TechCrunch homepage, you should see something similar to the image below: ![The TechCrunch homepage screenshot taken by Urlbox](/content/website-screenshots-aspnetcore/0c4b241e-0be1-4b9f-9469-a470c5e6ce32.png) The screenshot looks much better! You'll first notice that the ads are gone. The screenshot is also retina quality, resulting in superior image quality compared to the earlier screenshots. The banner at the page's bottom is also gone, thanks to the custom selector used in the code. Overall, this screenshot looks much better than the previous ones. ## Using Urlbox with Webhooks As a bonus exercise, you'll see how you can use webhooks with Urlbox to make API calls asynchronously. In other words, you can send a request for a screenshot without needing to wait for a response. Instead, Urlbox will send a JSON message to your specified webhook URL once the screenshot is complete. This one is a bit more tricky, but you know what you're doing! We'll need to expose 2 new POST endpoints, `/withWebhook` to send our request to and `/webhook` for Urlbox to send the JSON render response to. Our flow will be that we send a request via postman/curl/swagger, just as we did before, but to the `/withWebhook` endpoint. This will make a request to Urlbox asynchronously, with an Url for Urlbox to send the response to. Urlbox returns a unique Render ID as part of its asynchronous call, so we will use that as our reading list item ID, to keep our 'database' in sync with the render result. How do we expose this if we are working locally you ask? Sign up for [Ngrok](https://ngrok.com/), which with a CLI command exposes a port on your localhost. Once you've signed up and configured Ngrok, we can run the following, Exposing the port that your ASP NET server is running on, which you can find logged in your console when you run `dotnet run`. ```bash ngrok http <YOUR_PORT> ``` This should give you an endpoint like this: ![](/content/website-screenshots-aspnetcore/ngrok.png) Take that long URL on the left hand side which ends in `ngrok-free.app` so that we paste it in the code sample below, as that's where we'll want Urlbox to send the final render to. Leave ngrok running for now, as each time you rerun ngrok, it generates a new Url. Let's implement the screenshotting method. Head over to the `UrlboxScreenshotService.cs`. In there we'll mimic our previous method of rendering a screenshot, but now calling the async method in the SDK and adding in our new ngrok endpoint to the options, making sure to keep the appended `/ReadingList/webhook`: ```csharp public async Task<AsyncUrlboxResponse> ScreenshotUrlWebhook(string url) { UrlboxOptions options = Urlbox.Options(url) .WebhookUrl("https://3709-2a00-23c6-1a7f-c600-893e-193a-6b5c-f803.ngrok-free.app/ReadingList/webhook") .Format(Format.Png) .Width(1920) .Height(1080) .BlockAds() .HideCookieBanners() .Retina() .ClickAccept() .HideSelector(".pn-ribbon") .Build(); AsyncUrlboxResponse response = await _urlbox.RenderAsync(options); return response; } ``` This isn't DRY, but you're welcome to refactor as you wish! It will start a render, but not wait for the render to finish before responding. Checkout the [documentation](https://urlbox.com/docs/guides/sync-vs-async#synchronous-requests) for more information on the different request types you can make to Urlbox. Now we'll implement methods in our `ReadingListService.cs` to handle the incoming request from us, and the incoming webhook from Urlbox. In the `IReadingListService.cs` lets add the interfaces required for these methods: ```csharp using ReadingListApi.Services.ReadingList.DTO; using UrlboxSDK.Webhook.Resource; namespace ReadingListApi.Services.ReadingList { public interface IReadingListService { Task<Guid> CreateReadingItemAsync(ReadingItemCreateDTO readingItem); Task<byte[]?> GetReadingItemScreenshotAsync(Guid id); Task<IEnumerable<ReadingItemDTO>> ListReadingItemsAsync(); // Add in these methods Task<Guid> CreateReadingItemAsyncWithWebhook(ReadingItemCreateDTO readingItem); Task<Guid> ProcessWebhook(UrlboxWebhookResponse response); } } ``` Next, lets implement the two methods above. Head into the `ReadingListService.cs` and add this code: ```csharp public async Task<Guid> CreateReadingItemAsyncWithWebhook(ReadingItemCreateDTO readingItem) { if (_screenshotService is UrlboxScreenshotService urlboxScreenshotService) { // Take the screenshot AsyncUrlboxResponse response = await urlboxScreenshotService.ScreenshotUrlWebhook(readingItem.Url); // Create a new model for the reading item var model = new ReadingItemModel() { // Set the ID to the Urlbox render ID so we can match it later Id = Guid.Parse(response.RenderId), Reminder = readingItem.Reminder, Title = readingItem.Title, Url = readingItem.Url }; // Add the model to our "database" _readingItems.Add(model); return model.Id; } throw new Exception("Webhook processing not supported for this screenshot service."); } public async Task<Guid> ProcessWebhook(UrlboxWebhookResponse response) { // Get the item from our 'database' var item = _readingItems.FirstOrDefault(x => x.Id == Guid.Parse(response.RenderId)); if (item != null) { item.ScreenshotTaken = true; var fileName = $"{item.Id}.png"; var fullFilePath = Path.Combine(_configuration["ScreenshotsFolder"], fileName); // Get the Screenshot and save it to our 'database' HttpClient client = new(); Console.WriteLine("Found item under renderID, downloading image and saving..."); HttpResponseMessage image = await client.GetAsync(response.Result.RenderUrl); if (image.StatusCode == System.Net.HttpStatusCode.OK) { await File.WriteAllBytesAsync(fullFilePath, await image.Content.ReadAsByteArrayAsync()); Console.WriteLine("Image Saved."); } return item.Id; } else { Console.WriteLine("Item not found"); } throw new Exception("Could not get reading list item."); } ``` `CreateReadingItemAsyncWithWebhook()` takes our reading item from our POST request, just as before. We call the UrlboxScreenshotService method `ScreenshotUrlWebhook()` which returns an `AsyncUrlboxResponse`. This is an object the [SDK](https://github.com/urlbox/urlbox-dotnet?tab=readme-ov-file#asyncurlboxresponse) provides, which has a `RenderId` on it as well as some other useful things. It's this render ID we will use to store the model for retrieval later. `ProcessWebhook()` is the method that handles requests from Urlbox. It's going to be called by the controller's method triggered by the `/webhook` endpoint. It takes the finalised `UrlboxWebhookResponse`, and finds the item by the same Render ID Urlbox generated for us. It then takes the `RenderUrl`, which is the location in cloud storage where you can find your image, opens it and stores it in our 'database'. This location might be your S3 cloud storage location if you have it [setup](https://urlbox.com/docs/storage/configure-s3) with Urlbox. If you're also saving side renders like html, metadata or markdown through use of the methods like `.SaveMarkdown`, the Url's for them will also be here, and you could refactor this code to store them too. All the options and objects the SDK implements is in their [API reference](https://github.com/urlbox/urlbox-dotnet?tab=readme-ov-file#api-reference). Let's finally add the two endpoint methods to the `ReadingListController.cs`: ```csharp // ... previous endpoints [HttpPost("/withWebhook")] public async Task<IActionResult> CreateReadingItemAsyncWithWebhook(ReadingItemCreateDTO readingItem) { try { return Ok(await _readingListService.CreateReadingItemAsyncWithWebhook(readingItem)); } catch (Exception ex) { _logger.LogError("An error occurred while creating a reading item: {Exception}", new { Exception = ex }); return StatusCode(StatusCodes.Status500InternalServerError, "An error occurred while creating a reading item"); } } [HttpPost("webhook")] public async Task<IActionResult> ProcessWebhook([FromServices] IUrlbox urlbox) { StreamReader stream = new(Request.Body, leaveOpen: true); try { UrlboxWebhookResponse verifiedResponse = urlbox.VerifyWebhookSignature( Request.Headers["x-urlbox-signature"], await stream.ReadToEndAsync() ); Console.WriteLine("RESPONSE VERIFIED"); Guid processedId = await _readingListService.ProcessWebhook(verifiedResponse); } catch (Exception ex) { Console.WriteLine($"Error verifying response: {ex.Message}"); } return Ok(); } ``` Our new `/withWebhook` endpoint is practically the same as our previous create method, but just calls a different service method. This isn't DRY, and if you're using this code feel free to refactor this! It's just an example, not a prescription. The method attached to `/webhook` does something more jazzy. It injects the urlbox instance we have (arguably not SOLID, but again, this is just an example) in the service layer, and validates that the content being sent is indeed from Urlbox. This can be quite a tedious process to implement manually, so the SDK takes out most of that thinking with a simple method. Checkout the [documentation](https://urlbox.com/docs/webhooks#verify-webhook) on webhooks or the [source code](https://github.com/urlbox/urlbox-dotnet/blob/master/UrlboxSDK/Webhook/Validator/UrlboxWebhookValidator.cs) for an in-depth understanding of what's going on under the hood. Now for the pièce de résistance, we just need to add our webhook secret into the Urlbox instance. Head back into the `Program.cs` and add that bad boy in. You can find it on your dashboard's project settings underneath your publishable key and secret key under `Webhook Secret`: ```csharp // Add Urlbox to the DI container builder.Services.AddUrlbox(options => { options.Key = "YOUR_PUBLISHABLE_API_KEY"; options.Secret = "YOUR_SECRET"; // This one! options.WebhookSecret = "NEQG6yO7kYgiMiO3"; }); ``` Now that all of this is done, you should be able to run `dotnet run` again, hit the `/withWebhook` endpoint with the same JSON body as before, and get an ID. ```bash curl --location 'http://localhost:5021/withWebhook' \ --header 'Content-Type: application/json' \ --data '{ "title": "Urlbox", "reminder": "2026-02-05T19:00:00.000Z", "url": "https://www.urlbox.com/blog" }' ``` Use that ID in the GET screenshot method we implemented beforehand, and you'll see the generated screenshot. This is a great way to render screenshots on a larger scale, particularly if you're worried about tying up processing threads and keeping network requests open for a long time. There are many ways you could improve this, run these in cron jobs to batch requests during off-peak times. You could extend the /withWebhook method to accept a list of options you could pass yourself, including the webhook Url itself. ## Conclusion You might want to incorporate screenshots into your ASP.NET Core application for many reasons. In this article, you've seen how you can use different NuGet packages to take screenshots of a website locally. You also saw the benefit of using a screenshot service like Urlbox. With it, you can take ad-free, high-quality screenshots with minimal effort in an ASP.NET Core application. Finally, you learned how to use the webhook feature provided by Urlbox to take screenshots asynchronously. If you're looking for an easy, quick, and reliable way to create high-quality screenshots that stand out, look no further than [Urlbox](https://urlbox.com/.md). --- # Capturing Screenshots of Websites From URLs in C# > If you're a seasoned C# backend developer with limited JavaScript skills, chances are you don't want to maintain a Node.js application. Source: https://urlbox.com/website-screenshots-c-sharp Last updated: 2025-03-21 --- For many people, if you want to illustrate your blog post with a screenshot or two, it's no big deal. You take these screenshots manually, make a few quick edits, integrate them in your post, make it live, and forget about it. But what if you capture screenshots for a living? There are plenty of reasons that a C# developer might need to capture screenshots: - Using screenshots of your application in automated UI testing workflows that run several times a day. - Generating PDF documents with curated web content for your application's users. - Generating PDF invoices from a URL. - Monitoring websites for IP infringement and evidence collection. In scenarios like these, taking screenshots manually just doesn't cut it. You need to integrate some sort of automation library or [screenshot API](https://urlbox.com/screenshot-api.md). When you start to explore available options, you'll quickly realize that most of the libraries that automate capturing screenshots require a certain level of JavaScript mastery. If you're a seasoned C# backend developer with limited JavaScript skills, chances are you don't want to maintain a Node.js application. Learning a new language is all well and good, but you've got schedules and deadlines. You would probably prefer a library that lets you get the job done while using C#, a programming language you're already comfortable writing in. In this tutorial, you'll learn how to take screenshots in C# using different methods. You’ll learn how to create a C# project and set up an application that can be used to take screenshots of websites programmatically. You can find the code used in this article in this [GitHub repository](https://github.com/See4Devs/urlCapturing). ## Setting Up the Demo Project For this tutorial, you'll be using the [Visual Studio 2022 Community Version](https://visualstudio.microsoft.com/downloads). If you don't already have it installed, you'll want to do that before going any further. Open Visual Studio, then click on **New Project**, then select **Console Application**. ![C# console application](/content/website-screenshots-c-sharp/hdEYLb8.png) Next, On the “Target framework” select **.Net 6**. ![C# target framework](/content/website-screenshots-c-sharp/MRUk1ag.png) Configure your console application by naming your application "urlCapturing", and select the directory where you want to save your project. ![C# configure application](/content/website-screenshots-c-sharp/aj89sXD.png) Click **Create**, and your project will be created with default presets. ![C# defaut project](/content/website-screenshots-c-sharp/4k3ZuCX.png) To create a new folder, right-click on the “urlCapturing” project, and then click **Add**, then **New Folder**. Name the folder “services”. You'll be putting all of your service classes for the different screenshot-capturing methods in this folder. ![C# add new folder](/content/website-screenshots-c-sharp/d6KrSnO.png) Go to `Program.cs`, delete all the content, and paste in the following default class: ```csharp namespace urlCapturing { class Program { static void Main(string[] args) { } } } ``` This completes the basic project setup, and you can move on to taking screenshots. ![C# basic project setup](/content/website-screenshots-c-sharp/81cgJUA.png) ### Taking a Screenshot Using Selenium With ChromeDriver [Selenium](https://www.selenium.dev/) is an open source project for a range of tools. It helps you create robust, browser-based automation tests. It’s commonly used by quality assurance engineers, who write scripts for automating application tests rather than doing the work manually. You'll be using Selenium with ChromeDriver to programmatically open a website URL in the browser, take a screenshot, then close the browser. To start using Selenium, add the "Selenium.WebDriver" and "Selenium.WebDriver.ChromeDriver" NuGet packages to your project. To follow this tutorial, you'll also need to make sure you have the latest [Chrome browser](https://www.google.com/chrome/). ![C# NuGet packages](/content/website-screenshots-c-sharp/V1uGOkf.png) Next, create a new class called `SeleniumService` under the `services` folder, and add the following code: ```csharp using System; using OpenQA.Selenium; using OpenQA.Selenium.Chrome; namespace urlCapturing.services { public class SeleniumService { static IWebDriver driver; public void seleniumScreenShot() { driver = new ChromeDriver(); var weburl = "https://bbc.com"; driver.Navigate().GoToUrl(weburl); try { System.Threading.Thread.Sleep(4000); Screenshot TakeScreenshot = ((ITakesScreenshot)driver).GetScreenshot(); string imagePath = "./../../../selenium-screenshot.png"; TakeScreenshot.SaveAsFile(imagePath); } catch (Exception e) { Console.WriteLine(e.StackTrace); } driver.Quit(); } } } ``` The code above does the following : - Initiates ChromeDriver, so you can use Chrome. - Uses ChromeDriver to open the [BBC's website](http://bbc.com) on your machine. - Pauses the program for four seconds to ensure that the website has loaded. - Takes a screenshot of the targeted URL. - Saves the screenshot under the project directory. - Quits Chrome. To run the Selenium Service, update the `Program` class as follows: ```csharp using urlCapturing.services; namespace urlCapturing { class Program { static void Main(string[] args) { // Taking screenshots with Selenium var seleniumShot = new SeleniumService(); seleniumShot.seleniumScreenShot(); //end } } } ``` The code above does the following: - Creates a new instance of SeleniumService. - Calls the seleniumScreenShot() method, which is the function that takes a screenshot programmatically. Now run the program. This will result in a screenshot saved under your project directory. ![Screenshot with Selenium](/content/website-screenshots-c-sharp/GiPNhb4.png) This is a decent screenshot of the BBC website, but you can see that an ad was captured as well. While this screenshot looks fine, taking a screenshot of a scrollable page would be tricky using Selenium, as would getting an effective screenshot of a page that had pop-ups, cookie banners, or ads that obscured some of the content. Selenium isn't an out-of-the-box solution, and while you could customize the output, it would require significantly more resources and development to do so. ### Taking a Screenshot Using GrabzIt [GrabzIt](https://grabz.it/) is a tool that enables companies to capture screenshots from URLs and convert them into images, PDFs, .docx files, CSV files, as well as others. The tool features an API that you can use in your application to generate screenshots. To start using GrabzIt, add the "GrabzIt" NuGet package to your project. ![C# GrabzIt NuGet package](/content/website-screenshots-c-sharp/ZBE2baL.png) Once added, the NuGet package should start to download automatically. Go to the GrabzIt website and [create an account](https://grabz.it/login/create), then sign in to your account. Navigate to **API Documentation**, and scroll down to get your API key and API secret. ![GrabzIt credentials](/content/website-screenshots-c-sharp/b79PHbp.png) Create a new file called `settings.json` and add the following code with the API key and API secret into it: ```json { "GrabzItConfig": { "ApiKey": "Your API Key", "ApiSecret": "Your API Secret" } } ``` While you could provide your API key and secret as string literals, this is usually considered a bad practice because when using source control like Git, doing so leads to a leak of credentials. Instead, you'll create a JSON file to store your API key and secret, then build a configuration object to read their values. Configure the build system to copy `settings.json` to your project's output directory. To achieve this, do one of the following: - In your code editor, right-click the `settings.json` file, and select **Properties**. In the file property editor UI that appears, set "Copy to output directory" to "Copy if newer". - If the property editor UI is not available, open the `ScreenshotsWithUrlbox.csproj` file and paste the following code just before the closing `</Project>` tag: ```xml <ItemGroup> <None Update="settings.json"> <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> </None> </ItemGroup> ``` To be able to read the keys from the JSON file, you need to add “Microsoft.Extensions.Configuration.Binder” and “Microsoft.Extensions.Configuration.Json”, two NuGet packages. ![Configuration NuGet Packages](/content/website-screenshots-c-sharp/YrE8Bdr.png) Next, create a new class called `GrabzItService` under the `services` folder, and add the following code: ```csharp using GrabzIt; using Microsoft.Extensions.Configuration; namespace urlCapturing.services { public class GrabzItService { public void grabzItShot() { var grabzItConfig = new ConfigurationBuilder() .SetBasePath(AppDomain.CurrentDomain.BaseDirectory) .AddJsonFile("settings.json").Build(); string apiKey = grabzItConfig.GetSection("GrabzItConfig:ApiKey").Value; string apiSecret = grabzItConfig .GetSection("GrabzItConfig:ApiSecret") .Value; var weburl = "https://bbc.com"; //Create the GrabzItClient class GrabzItClient grabzIt = new GrabzItClient(apiKey, apiSecret); // To take a image screenshot grabzIt.URLToImage(weburl); string imagePath = "./../../../grabzIt-bbc.jpg"; grabzIt.SaveTo(imagePath); } } } ``` The above code does the following: - Creates a configuration object, which grabs the keys from the JSON file using the ConfigurationBuilder() method. - Saves the GrabzIt keys into string variables. - Creates an instance of the GrabzIt client. - Calls URLToImage(), the method that will take the screenshot of a web URL. - Saves the screenshot image under the project directory. To run the GrabzIt Service, update the "Program" class by pasting the following code in at the end of the existing code: ```csharp // Taking screenshots with GrabzIt var grabzItShot = new GrabzItService(); grabzItShot.grabzItShot(); //end ``` Now run the program, and you should get a screenshot saved under your project directory. ![Screenshot with GrabzIt](/content/website-screenshots-c-sharp/PCMIvan.png) As you can see, if you want to take a full-page screenshot using GrabzIt, you'll find that it's fairly tricky—you can’t do it dynamically without knowing the dimensions of the page you're trying to capture. Additionally, the cookie pop-up banner is appearing at the top of the page, and it's not feasible to bypass this using GrabzIt. ### Taking a Screenshot Using Urlbox Urlbox is a simple and focused website screenshot API. It supports full-page screenshots as a single image, and responsive screenshots that allow you to simulate different screen sizes—it even allows you to pass a user-agent string to take a screenshot of mobile-optimized sites. You can fine tune the look of your screenshots by blocking specific sections, dismissing cookie banners, and blocking pop-ups and ads. First, create a Urlbox account. To create an account, go to the [Urlbox website](https://urlbox.com/screenshot-api.md) and click **Sign up for free**, which will give you a free seven-day trial of Urlbox. Fill in your details, set a password, and click **Let's get started**. Confirm your email, then click **New Screenshot** to experiment with Urlbox's features in a visual environment. Keep in mind that your trial gives you a hundred unique screenshot captures, so be sure not to run out of them before you have a chance to write any C# code. In order to use Urlbox in our C# code we'll need a project's API key, secret, and webhook secret if we want to set that up. To get this, navigate to the **settings** tab using the sidebar. This will bring up a list of your projects. On a new account you'll only have one project `default`. Open that project up and you should see the below. Take note of your API key and API secret, as shown below. You'll need to pass these with your Urlbox API calls. ![Urlbox dashboard](/content/website-screenshots-c-sharp/dashboard.png) To start using Urlbox, add the "Urlbox" NuGet package to your project. You can do this via nuget packages, or in the cli: ```bash dotnet add package Urlbox.sdk.dotnet --version 2.0.1 ``` Before you can take screenshots with Urlbox, you'll need to integrate your API key and secret into your .NET application. In `settings.json`, add the following snippet to the existing code, replacing the placeholder text with your key and secret: ```JSON "UrlBoxConfig": { "ApiKey": "Your API Key", "ApiSecret": "Your API Secret", "WebhookSecret": "Your Webhook Secret" } ``` Under the "services" folder, create a new class called "UrlboxService" and add the following code: ```csharp using Microsoft.Extensions.Configuration; using UrlBox; namespace urlCapturing.services { public class UrlBoxService { public async void urlBoxScreenShots() { var urlBoxConfig = new ConfigurationBuilder() .SetBasePath(AppDomain.CurrentDomain.BaseDirectory) .AddJsonFile("settings.json").Build(); string apiKey = urlBoxConfig.GetSection("UrlBoxConfig:ApiKey").Value; string apiSecret = urlBoxConfig.GetSection("UrlBoxConfig:ApiSecret").Value; string webhookSecret = urlBoxConfig.GetSection("UrlBoxConfig:WebhookSecret").Value; Urlbox urlbox = Urlbox.FromCredentials(apiKey, apiSecret, webhookSecret); string url = "https://bbc.com"; // Simple screenshot UrlboxOptions options = Urlbox.Options(url).Build(); string outputSimple = urlbox.GenerateSignedRenderLink(options); Console.WriteLine(outputSimple); // Fullscreen without Ads and cookie banners UrlboxOptions optionsFullPageNoAds = Urlbox.Options(url).FullPage().BlockAds().Build(); string outputFullNoAds = await urlbox.GenerateSignedRenderLink(optionsFullPageNoAds); Console.WriteLine(outputFullNoAds); // Retina quality, based on subset of a page UrlboxOptions optionsRetina = Urlbox.Options(url) .Width(768) .UserAgent("mobile") .Retina() .BlockAds() .HideCookieBanners() .Selector(".module--editors-picks") .Delay(10) .FailIfSelectorMissing() .FailOn4xx() .FailOn5xx() .Build(); string outputRetina = await urlbox.GenerateSignedRenderLink(optionsRetina); Console.WriteLine(outputRetina); // PDF UrlboxOptions optionsPdf = Urlbox.Options(url) .Format(Format.Pdf) .FullPage() .BlockAds() .HideCookieBanners() .Highlight("bbc") .Highlightbg("red") .Highlightfg("white") .Build(); string outputPdf = await urlbox.GenerateSignedRenderLink(optionsPdf); Console.WriteLine(outputPdf); } } } ``` The above code does the following: - Creates a configuration object that users the ConfigurationBuilder() method to grab the keys from the JSON file. - Saves the Urlbox keys as string variables. - Creates an instance of the Urlbox client. - Generates links which when you run a GET request to them render screenshots, including simple, fullscreen, retina, and pdf. To run the Urlbox Service, update the "Program" class by adding the following code at the end of the existing code: ```csharp // Taking screenshots with UrlBox var urlBox = new UrlBoxService(); urlBox.urlBoxScreenShots(); //end ``` Run your program, and it will return console output of URLs for different screenshot options. ![Console output](/content/website-screenshots-c-sharp/69eMUmJ.png) Go to your browser and visit these urls. ## Simple Screenshot When you call the `GenerateSignedRenderLink()` method, the Urlbox SDK puts together an url using your credentials and options given. When you run a GET request to these render links, the Urlbox API generates a screenshot and returns it to you syncronously. This is really handy for image embedding. ![Screenshot using Urlbox with default settings](/content/website-screenshots-c-sharp/simplerender.png) ## Clean, Full-Page Screenshots This screenshot is significantly larger than the first one, and you'll notice it takes a little longer to render too. If you look closely at the top part of the screenshot, you'll see that the iframe with ads, usually displayed between the navigation bar and the main content, is nowhere to be found. ## A Retina-Quality PNG Screenshot Based on a Subset of a Page What if you're only interested in capturing a specific part of a page? Maybe you want to emulate a mobile device and max out on pixel ratio. To do so, you used the following options in your code for the request: ```csharp UrlboxOptions optionsRetina = Urlbox.Options(url) .Width(768) .UserAgent("mobile") .Retina() .BlockAds() .HideCookieBanners() .Selector(".header-content") .Delay(10) .FailIfSelectorMissing() .FailOn4xx() .FailOn5xx() .Build(); ``` - `Width` sets the viewport width of the browser used to capture a screenshot. 768 pixels is the width of an iPad Air Mini in portrait orientation. - `UserAgent` instructs Urlbox to use a mobile-like user agent setting. - `Retina` requests a high-definition screenshot with a device pixel ratio of @2x. - `BlockAds` and `HideCookieBanners` strip out ads and cookie banners, respectively. - `Selector` tells Urlbox to focus on a specific element using the [CSS selector syntax](https://www.w3schools.com/cssref/css_selectors.asp). - `Delay` is the amount of time Urlbox waits before taking a screenshot. If the target page is especially large or image heavy, it can be useful to give it a little extra time to load completely before capturing the screenshot. - `FailIfSelectorMissing` tells Urlbox to return an error if it doesn't find the selector specified above. If this property is not set, Urlbox defaults to taking the full page screenshot, which may not be the intended behavior. - `FailOn4xx` and `FailOn5xx` ensure that instead of capturing whatever the browser renders, UrlBox returns an error if requesting the target page results in an HTTP error in the 4xx and 5xx range, respectively. This results in a retina-quality PNG screenshot that emulates a mobile device and only shows a section of the target page. Because the `Retina` property was set to true, the width of the resulting screenshot is 1536 pixels, which is exactly double the requested 768-pixel width. ## A Full-Page PDF Document With Highlights Urlbox API isn't limited to capturing screenshots in the PNG format. You can use a whole host of formats including PDF. To do so, the following options were included in your code for the request: ```csharp UrlboxOptions optionsPdf = Urlbox.Options(url) .Format(Format.Pdf) .FullPage() .BlockAds() .HideCookieBanners() .Highlight("bbc") .Highlightbg("red") .Highlightfg("white") .Build(); string outputPdf = await urlbox.GenerateSignedRenderLink(optionsPdf); Console.WriteLine(outputPdf); ``` - `Format` changes the format of the outputted screenshot. - `FullPage` takes a screenshot of the whole page. - `BlockAds` blocks any advertisements from showing up on the page. - `PdfBackground` excludes any background images that the target HTML page uses from the capture. - `Highlight` is a string that Urlbox searches for in the target page. If found, all occurrences will be highlighted. Although introducing text highlights arguably makes more sense in PDFs, note that this property isn't PDF-specific—you can use it with PNG screenshots, too. - `HighlightBg` and `HighlightFg` define the text highlight's background and foreground colors. This results in a long PDF document that includes the entire content of the target page, strips out ads, and highlights any occurrence of "BBC". ![Partial view of PDF with highlights](/content/website-screenshots-c-sharp/pdf.png) For the full list of available options that the Urlbox API provides, see the [Urlbox Options reference](https://urlbox.com/docs/options.md). ## Conclusion In this tutorial, you've created several simple C# programs using tools like Selenium, GrabzIt, and Urlbox to take screenshots programmatically. Urlbox stands out from tools like Selenium and GrabzIt because it also offers out-of-the-box features such as high-DPI images that look great on retina screens, pop-up blocking, automatic dismissal of cookie banners to prevent them spoiling your screenshots, ad blocking, and automatic CAPTCHA bypass. Handling issues like this with other tools is time-consuming and costly, and requires writing extensive custom code—possible but inefficient. [Urlbox](https://urlbox.com/.md) is a fast and accurate screenshot rendering service at scale. It offers many options, such as blocking ads and pop-ups, or even changing the appearance of a page with custom CSS or JavaScript. If you need a seamless screenshot solution that integrates into your workflow, give Urlbox a try. --- # How to Take a Screenshot of a Web Page with Clojure > This article will show you how to take screenshots of webpages in an ASP.NET Core application without JavaScript. Source: https://urlbox.com/website-screenshots-clojure Last updated: 2025-03-21 --- As programmers, the need for taking screenshots of web pages programmatically occurs in many situations. For example, when you write automation tests, you may want to take screenshots to compare the rendered web pages with the expected web pages. Or you might want to generate an image preview of the content of the dynamic web pages served by your application to post to social media. Another use case is web scraping, where you want to take screenshots of web pages from various websites. In this tutorial, you'll learn how to take screenshots of web pages in Clojure using different methods: - A Clojure WebDriver called Etaoin - A Headless ChromeDriver called Puppeteer, wrapped by ClojureScript - A service called Urlbox ## Taking Screenshots with Etaoin [Etaoin](https://github.com/clj-commons/etaoin) implements the WebDriver protocol in pure Clojure. WebDriver is a remote control interface that enables introspection and control of browsers. Etaoin controls web browsers via their WebDrivers, and each browser has its own WebDriver implementation that must be installed and launched. For this tutorial, you'll be using Chrome. You'll need to install [ChromeDriver](https://sites.google.com/chromium.org/driver/downloads) with the following command: [ChromeDriver](https://sites.google.com/chromium.org/driver/): - macOS: `brew install chromedriver` - Windows: `scoop install chromedriver` You launch the ChromeDriver, by executing the following command in your terminal: ``` chromedriver ``` Now, you create a Clojure project and add Etaoin to your project dependency list by putting the following into the `:dependencies` vector in your `project.clj` file: ```clojure [etaoin "0.4.6"] ``` Or the following under `:deps` in your `deps.edn` file: ```clojure etaoin/etaoin {:mvn/version "0.4.6"} ``` The code for taking a screenshot is straightforward. Here is how to take a screenshot of an article on TechCrunch: ```clojure (ns screenshots.demo (:require [etaoin.api :as e])) (def driver (e/chrome)) (e/go driver "https://techcrunch.com/2022/08/04/the-5-biggest-takeaways-from-teslas-cyber-roundup/") (e/screenshot driver "etaoin-techcrunch.png") ``` The screenshot looks like this: ![Etaoin screenshot](/content/website-screenshots-clojure/qAhnecu.png) Etaoin provides many features to control the browser, such as waiting for an element to be present on the page, or controlling the viewport size. You can learn more about it in [Etaoin user guide](https://github.com/clj-commons/etaoin/blob/master/doc/01-user-guide.adoc). Taking full-page screenshots with Etaoin is possible, but because taking a full-page screenshot is not part of the [WebDriver W3C screen capture standard](https://www.w3.org/TR/webdriver/#screen-capture), it requires browser-dependent custom code that is also browser dependent. For example, here is the code for taking a full-page screenshot with the Chrome browser: ```clojure (let [resp (e/execute {:driver driver :method :get :path [:session (:session driver) "screenshot" "full"]}) b64str (some-> resp :value)] (with-open [out (io/output-stream "etaoin-techcrunch-full-page.png")] (.write out ^bytes (-> (Base64/getDecoder) (.decode b64str))))) ``` The benefits of Etaoin are that it is written in pure Clojure and that, while this example uses Chrome, Etaoin works with multiple browsers. This ability is particularly important in the context of automation tests, where you need to check how your application behaves with various browsers. The main challenge with Etaoin is that you need to install and launch the browser manually. It is particularly challenging if you want to take screenshots in production or as part of your continuous integration flow. Moreover, as you may have noticed in the TechCrunch homepage screenshot above, there's no ad-blocking ability, so advertisements appear in the screenshot. In the next section, you'll explore a solution that avoids the need to launch the browser manually. ## Taking Screenshots with Puppeteer [Puppeteer](https://github.com/puppeteer/puppeteer) is a [Node.js](https://nodejs.org/en/) library that provides a high-level API to control Chrome over the [DevTools Protocol](https://chromedevtools.github.io/devtools-protocol/), a protocol that allows for tools to instrument, inspect, debug, and profile Chrome. You can easily use Puppeteer inside a ClojureScript program by using [shadow-cljs](https://shadow-cljs.github.io/docs/UsersGuide.html) as your build tool. With shadow-cljs, using npm modules works like a charm. The only thing you need to do is to create a ClojureScript project and add `puppeteer` to your dependencies in `package.json`, by executing: ``` npm add puppeteer ``` And here is the ClojureScript code for taking a screenshot of another article from TechCrunch: ```clojure (ns screenshot-demo.core (:require ["puppeteer" :as p])) (-> (p/launch) (.then (fn [browser] (.newPage browser))) (.then (fn [page] (-> (.goto page "https://techcrunch.com/2022/08/04/hbo-hbo-max-and-discovery-report-a-combined-total-of-92-1m-subscribers-plans-for-major-restructuring/") (.then (fn [_] (.screenshot page #js {:path "/tmp/puppeteer.png"}))) (.then #(println "Done!")))))) ``` Puppeteer, being a JavaScript library, deals with promises, which is why the code is made of several `(.then ...)` expressions. If you're not already familiar with JavaScript, you may find it frustrating. Here is the result: ![Puppeteer screenshot](/content/website-screenshots-clojure/iD2CXfd.png) With Puppeteer, taking a full-page screenshot is much simpler than with Etaoin. You need to add`:fullPage true` to the option map passed to `(.screenshot ...)`: ```clojure (.screenshot page #js {:path "/tmp/puppeteer.png" :fullPage true}) ``` Like Etaoin, Puppeteer provides many ways to control the browser, such as waiting for an element to be present on the page, or controlling the browser viewport. You can learn more about it in [Puppeteer API reference](https://pptr.dev/api/). The main benefit of Puppeteer is that it doesn't require installing and launching the browser manually. Puppeteer takes care of everything. However, one of the major drawbacks of Puppeteer is that it offers limited ability to control the browser. There's no way to dismiss a cookies warning or bypass a CAPTCHA, for example. Like Etaoin, Puppeteer requires managing a server. It is not as easy as it might sound. For example, a Puppeteer-based server on Heroku wasn't able to handle multiple requests in parallel and crashed, probably due to the process memory limitation on Heroku. In the next section, you'll look at a solution that doesn't require managing a server. ## Taking Screenshots with Urlbox So far, you've seen how to take screenshots by using third-party libraries that allow you to control a web browser. The main challenge with this approach is that you have to run a headless web browser as part of your production system. A simpler approach is to use an external service like [Urlbox](https://urlbox.com/.md). Urlbox is a service that provides a simple and flexible [screenshot API](https://urlbox.com/screenshot-api.md)I, and lets you avoid the need to manage and maintain your own server for taking screenshots. Moreover, Urlbox can block ads out of the box. In order to use Urlbox, you need to create an account at [Urlbox](https://urlbox.com/.md) and retrieve your API token from [it](https://urlbox.com/dashboard.md). Once you have an API token, taking a screenshot is as simple as accessing a URL. The URL is made of: - Urlbox API endpoint: `https://api.urlbox.com/v1/` - API token - Desired image format (PNG, JPG, JPEG, AVIF, WebP, PDF, SVG, HTML) - Query parameters with the encoded URL of the web page that you want to take a screenshot of For instance, you can take a PNG screenshot of `https://techcrunch.com/2022/08/04/hbo-hbo-max-and-discovery-report-a-combined-total-of-92-1m-subscribers-plans-for-major-restructuring/` by accessing `https://api.urlbox.com/v1/api-token/png?url=https%3A%2F%2Ftechcrunch.com%2F2022%2F08%2F04%2Fhbo-hbo-max-and-discovery-report-a-combined-total-of-92-1m-subscribers-plans-for-major-restructuring%2F`. Here is the result: ![Urlbox screenshot](/content/website-screenshots-clojure/Sl1nmhQ.png) In addition, the Urlbox API provides several options to configure the screenshot. For instance, in order to take a full-page screenshot, you can pass `full_page=true` as an additional query parameter. The full list of options is available at [Urlbox options reference](https://urlbox.com/docs/options.md). You can interact and experiment with the various options at [Urlbox online dashboard](https://urlbox.com/dashboard/screenshot.md). The dashboard looks like this: ![Urlbox dashboard](/content/website-screenshots-clojure/2VROxlj.png) Now, let's write a piece of Clojure code that: - receives a map of options - converts it to a Urlbox URL - accesses the URL - saves a file with the image You can use Clojure libraries to save you time writing low-level code: - `lambdaisland.uri` to convert maps to encoded URL parameters - `http-client` to access Urlbox endpoint ```clojure (ns screenshot-demo.urlbox (:require [clj-http.client :as http] [lambdaisland.uri :refer [map->query-string]] [clojure.java.io :as io])) ``` This is a function that receives a token, an image format, and an options map, and returns the corresponding Urlbox URL: ```clojure (defn urlbox-url [token image-format options] (str "https://api.urlbox.com/v1/" token "/" image-format "?" (map->query-string options))) ``` And here is a little utility function to save binary files: ```clojure (defn save-binary! [path content] (with-open [w (io/output-stream path)] (.write w content))) ``` Now, let's take a screenshot of the article "Screenshot" on Wikipedia: ```clojure (def url "https://en.wikipedia.org/wiki/Screenshot") (def token "<your-token>") (->> (http/get (urlbox-url token "jpg" {:url url :height 200}) {:as :byte-array :throw-exceptions false}) :body (save-binary! "/tmp/screnshot.jpg")) ``` Notice how easy it is to control the height of the browser viewport by setting `:height 200` in the option map. Here's the result: ![Wikipedia screenshot](/content/website-screenshots-clojure/UsYGnQ8.jpg) The main benefit of Urlbox is that you don't have to deal at all with the management of a web service that runs the browser. Everything is taken care of by Urlbox. Urlbox can also block ads, bypass CAPTCHAs, simulate user interaction, and offers a [wide array of options](https://urlbox.com/docs/options.md) when it comes to controlling the look of the finished screenshot. ## Wrapping Up In this article, you've looked at multiple approaches to taking screenshots of web pages in Clojure and ClojureScript. Solutions like [Etaoin](https://github.com/clj-commons/etaoin) and [Puppeteer](https://github.com/puppeteer/puppeteer) give you full control of the underlying web browser, but they require you to manage a web server, and offer limited control over what the final screenshot looks like. A solution like [Urlbox](https://urlbox.com/.md) spares you from needing to manage a server and a browser in production. The only thing that you have to deal with is the generation of the URL programmatically, which is straightforward in a language like Clojure. All the complexity of the browser and server management in production is taken care of by the service, freeing you up to spend your time on your core business functions. --- # Scripts to Take Website Screenshots from the Command Line (Linux and macOS) > This article will show you how to take screenshots of webpages from the command line. Source: https://urlbox.com/website-screenshots-command-line Last updated: 2025-03-21 --- Screenshots are useful for just about any aspect of your developer workflow. From grabbing a quick image of each page from a list of URLs in a database, to capturing the current state of your web app, screenshots can provide context for data in your SQL database or simply be used to guide design decisions at your organization. You might even want to use screenshots to dynamically generate images from HTML and CSS for use on social media. There is almost no limit to how you can use screenshots in your day-to-day work. In this article, you will learn methods for taking screenshots that can be used on both the Linux and macOS command line. You will also learn about [Urlbox](https://urlbox.com/.md), a tool to capture screenshots of websites at scale. If you'd like to see all the code from this tutorial in one place, you can do so in [this GitHub repository](https://github.com/unforswearing/scripts_to_take_website_screenshots). ## Puppeteer Many of the tools in this article take advantage of "headless" Chrome. Headless, in this case, means that Google Chrome can be run and managed without directly interacting with a browser window. The "headless" option for Google Chrome was released with version 59. However, since Google released [Puppeteer](https://pptr.dev/), taking screenshots with Chrome has become much easier. To get started capturing screenshots with Puppeteer, be sure you have [Node.js](https://nodejs.org/en/) and [npm](https://www.npmjs.com/) installed on your machine. To install Puppeteer, start by creating a folder for your project. Navigate to this folder in your terminal and install Puppeteer with the following command: `npm install puppeteer` Press "Enter", and you should see the Puppeteer library download and install. Once Puppeteer is installed, create a new file called `index.js` in the project folder you created above. Your code will run from this file to capture the screenshot, which will be saved in the same directory. In this example, the screenshot will be 500 x 1000. ```javascript // load Puppeteer const pt = require("puppeteer"); // this script accepts a url as an argument let url = new URL(process.argv[2]); // the filename will be extracted from the hostname of the url let filename = `${url.hostname}.png`; const delay = (ms) => new Promise((resolve) => setTimeout(resolve, ms)); // launch Puppeteer and add image parameters pt.launch().then(async (browser) => { const p = await browser.newPage(); // capture an image that is 1000 x 500 pixels await p.setViewport({ width: 1900, height: 1200 }); // navigate to the site you would like to capture await p.goto(url, { waitUntil: "domcontentloaded" }); delay(5000).then(async () => { // take the screenshot of the site and save it to the current folder await p.screenshot({ path: filename }); // close the Puppeteer browser when you are finished. await browser.close(); console.log("done"); }); }); ``` To run the above script, enter `node index.js https://www.geeksforgeeks.org/category/guestblogs/` in your terminal. The script will take a few moments to navigate and capture the screenshot, and it will print "done" when it is complete. ![Screenshot captured with Puppeteer](/content/website-screenshots-command-line/rXJgb0v.png) With Puppeteer you have a fully featured JavaScript library that can do a lot more than take screenshots, including interacting with the Document Object Model (DOM) of a website, responding to events, and accessing the virtual keyboard via API. These features make Puppeteer a dream if you are looking to interact with websites from the command line. One major negative is that Puppeteer requires knowledge of JavaScript or TypeScript to use more advanced features, which may be difficult if you are not familiar with one of the languages. Puppeteer requires you develop your own screen capture delay or request option functions, making development much more complicated. Another issue is that Puppeteer can't block ads or pop-ups from appearing in your screenshots, which means that any image you capture will potentially have these unneeded elements obstructing part of the image. While Puppeteer is a great option if you like the JavaScript ecosystem, it may be a bit much for your needs. ## Playwright Another useful library for capturing screenshots is [Playwright](https://playwright.dev/). Playwright is similar to Puppeteer in that it allows you to easily capture screenshots with a few lines of code. However, Playwright also allows you to capture screenshots from other browser engines, such as WebKit (Safari) and Firefox. As with the Puppeteer example, the code below will navigate to a web page of your choosing, take a screenshot, and save the screenshot PNG file to the same folder as the code. To get started, create a project folder and navigate to that folder in your terminal. Next, install Playwright using npm: ``` npm init playwright@latest ``` Note that the install process for Playwright is a bit different than Puppeteer. Playwright will guide you through the process of setting up your default language—JavaScript or Typescript, or you can choose to write a script with Python, .Net, or Java. For this tutorial, you'll be using JavaScript, the default language. After you select your options, npm will download the Chrome, WebKit, and Firefox browser engines to your project folder. After you have completed the Playwright setup, copy the code below and save it in the project folder as `index.js`: ```javascript // this example uses chromium. you may also use 'webkit' or 'firefox' const chromium = require("playwright").chromium; let url = new URL(process.argv[2]); let filename = `${url.hostname}.png`; (async () => { // launch a chromium instance const browser = await chromium.launch(); // create and load a new page 'context' const context = await browser.newContext(); const page = await context.newPage(); // navigate to your url await page.goto(url.href.toString()); await page.waitForEvent("requestfinished").then(async () => { // take the screenshot await page.screenshot({ path: filename }); // close the chromium instance await browser.close(); }); })(); ``` Now you can run the code to take a screenshot of your desired URL by entering the following command in your terminal: ``` node index.js https://www.geeksforgeeks.org/category/guestblogs/ ``` Your script will pause briefly while Playwright navigates to the URL specified in the code. When the script is complete, your screenshot will be saved to the current project folder. ![Screenshot captured with Playwright](/content/website-screenshots-command-line/YDuoeVr.png) Playwright is very similar to Puppeteer and using Playwright will provide you with several advantages. Playwright allows you to manipulate websites using the Webkit and Firefox browser engines as well as Google Chrome, which could provide flexibility depending on your use case. Playwright also allows you to use TypeScript, Python, .Net, or Java in addition to JavaScript, so you are not limited to a single language and development environment to create your scripts. Unfortunately, like Puppeteer, Playwright requires knowledge of several specific programming languages to develop, and some of the options may be a bit difficult to understand. Additionally, as you can see, it doesn't offer an easy way to block ads or banners on the site you're screenshotting. It is possible to remove elements using Playwright, however, it requires your script to find and hide the specific element showing the advertisement. ## Python JavaScript isn't the only language you can use to take screenshots of websites. [Selenium](https://selenium-python.readthedocs.io/) is a popular Python library that allows you to interact with websites and collect information from the comfort of your terminal. Using Python 3, Selenium, and [webdriver-manager](https://github.com/SergeyPirogov/webdriver_manager) you can quickly start taking screenshots of any site you desire. Before you get started, be sure you have Python 3 installed in your system by running the following command in your terminal: ``` python -version ``` If the output of this command shows the currently installed Python version you are good to go. If not, head over to the [Python releases page](https://www.python.org/download/releases/) and download the latest Python version for your system. Once you've verified that you have Python 3 installed, create a folder for this project, and navigate to this folder in your terminal. In your project directory, you can install Selenium and webdriver-manager using pip: ``` pip3 install selenium webdriver-manager ``` Next, create a file in your project directory called `main.py` and paste the following code into it: ``` import sys from selenium import webdriver from webdriver_manager.chrome import ChromeDriverManager # note: Selenium does not provide a way to resize the screenshot # this script accepts a url as the first argument url = sys.argv[1] # pass a filename to the script as the second argument filename = sys.argv[2] # set up webdriver chromedriver = webdriver.Chrome(ChromeDriverManager().install()) # navigate to the url chromedriver.get(url) # save the screenshot to `filename` chromedriver.save_screenshot(filename) # quit the Chrome webdriver chromedriver.quit() print("done") ``` Finally, run the script in your terminal using the following command: ``` python3 main.py https://www.geeksforgeeks.org/category/guestblogs/ geeksforgeeks.png ``` Your script will show a progress bar as it attempts to open the website. Unlike with Playwright and Puppeteer, the above script does not run headless, meaning you'll see a Chrome window open briefly while the screenshot is captured, but no interaction is needed from you. The screenshot will save to your current project directory. ![Screenshot captured with Selenium and Python](/content/website-screenshots-command-line/RsZY8pR.png) Selenium and webdriver-manager offer a simpler way of taking screenshots than the previous Puppeteer and Playwright examples, and like Playwright, Selenium allows you to use your choice of browser engine to interact with websites. Selenium is a fantastic tool if Python is your preferred programming language, and requires minimal setup to get started. However, while Selenium and webdriver-manager are a bit easier to use than the previous examples, the screenshot produced is decidedly subpar. The image captured with this script is low in quality, containing fuzzy text, which may limit the usability of this image in your project. Another snag is that Selenium has few customization options. You're not able to specify an image size for your captures, and while this image doesn't show any ads, Selenium doesn't actually offer ad blocking or banner dismissal. The lack of ads is actually indicative of another drawback with Selenium: the site didn't fully load before the screenshot was captured, which will require more scripting to work around. ## shot-scraper [shot-scraper](https://shot-scraper.datasette.io/) is a command line tool built on top of Playwright, developed by Simon Willison. Having Playwright as the underlying process means that shot-scraper is easier and faster than developing your own script, and doesn't require you to set up a programming environment or write much code. shot-scraper is available through pip, and can be installed using the following command: ``` pip install shot-scraper ``` Once installed, you will need to run an additional command to install the browser engine: ``` shot-scraper install ``` And that's it—you're ready to capture screenshots with shot-scraper. Since shot-scraper is a standalone command rather than a library, you can use it directly from the command line: ``` shot-scraper https://www.geeksforgeeks.org/category/guestblogs/ ``` You may also set up a simple `bash` script for `shot-scraper`. The code below accepts a URL as an argument, and will save the screenshot to your current directory: ``` #!/usr/bin/env bash url="${1}" shot-scraper "${url}" ``` ![Screenshot captured with shot-scraper](/content/website-screenshots-command-line/SPp5aQx.png) shot-scraper has [many options available](https://shot-scraper.datasette.io/en/stable/), and doesn't require that you write any additional Python or JavaScript. Using Playwright as the underlying architecture allows shot-scraper to be a robust and full-featured tool that is very easy to use. While shot-scraper is easy to get started with, adding additional options to your command may require you to create a bash or Python script. Additionally, advanced options such as hiding selectors or highlighting keywords will require you to write additional code. More complex workflows with shot-scraper can quickly grow to meet or exceed the size of a Playwright or Puppeteer script. Finally, while this screenshot doesn't have ads, shot-scraper doesn't offer ad blocking, so their absence is again likely because the page didn't fully load before the screenshot was taken. ## gowitness Unlike the JavaScript and Python examples above, [gowitness](https://github.com/sensepost/gowitness) is a standalone command that can be run directly in your terminal. The benefit to using gowitness over the other options is that you don't need to know or learn a new programming language to use it—if you're familiar with the command line environment, running gowitness is a smooth process. Before you get started, be sure you have [Go](https://go.dev/) installed and that the Go binary is in your path. Once Go is set up on your machine, you can download gowitness by running the following command in your terminal: ``` go install github.com/sensepost/gowitness@latest ``` Once gowitness has been installed, create a project folder, and navigate to that folder in your terminal. To create the run script for gowitness, copy the code below and save it as `screenshot.bash` in your project folder: ``` #!/usr/bin/env bash # make sure gowitness is installed and in your path command -v gowitness && { # if your terminal can find the gowitness tool, create the screenshot gowitness single -o ./ "https://www.geeksforgeeks.org/category/guestblogs/" } || { print "gowitness is not found." } ``` As mentioned above, creating a script isn't required to use gowitness. However, the command's options are a bit verbose, so you may want to save more complicated screenshot scripts to a standalone file, such as the `screenshot.bash` script mentioned above. Use the following command to capture a single screenshot of a webpage with `gowitness`: ``` #!/usr/bin/env bash # make sure gowitness is installed # if gowitness is found, capture the image command -v gowitness && { gowitness single –resolution-x 800 –resolution-y 1200 -o ./ "https://www.geeksforgeeks.org/category/guestblogs/" } || { print "gowitness is not found." } ``` On your first run of the program, it creates a "screenshots" directory, which will store all screenshots, as well as a SQlite database file that will store logs, request headers, TLS certificates, and requested URLs. This may be excessive for some use cases, and unnecessary if you are using gowitness as a part of a larger program or process. gowitness has a wealth of options available, including options to source URLs from a file or standard input, using screenshot services from `nmap` XML files, creating reports, and creating a web service that can take screenshots on your behalf. These options make `gowitness` a fairly robust tool, however there are no options to block ads. Additionally, the process of saving a screenshot with gowitness is also very slow, which means that any script using gowitness may take much longer to execute than other options listed. ![Screenshot captured with gowitness](/content/website-screenshots-command-line/9WTJRM4.png) gowitness has the benefit of simplicity—it is easy to install and use immediately, without any set up beyond installing the command from GitHub or by using `go get…` in your terminal. This is a great option if you want to get started quickly, or if you're a Golang enthusiast and want to contribute to the codebase. Despite the ease of use, gowitness shares a number of issues presented by previous solutions. It does not have the ability to block ads, so these will show up in any image captured using this tool. Additionally, gowitness does not provide a command to wait until the page is fully loaded before capturing the screenshot, which limits the usability of the tool for slow-loading websites. You can see both of these issues in the screenshot above. ## rustywitness [rustywitness](https://github.com/swanandx/rustywitness) is a slimmed-down version of gowitness, offering fewer options in exchange for increased ease of use. Both gowitness and rustywitness use headless Chrome to interact with URLs, and both programs will allow you to capture screenshots from URLs listed in a text file. You can install rustywitness from the [GitHub project releases](https://github.com/swanandx/rustywitness/releases/tag/v0.1.0). If you already have the [Cargo package manager](https://doc.rust-lang.org/cargo/) installed on your machine, you can install rustywitness by using the following command: ``` cargo install rustywitness ``` To capture a screenshot with rustywitness, you can use the following command in your terminal: ``` rustywitness "https://www.geeksforgeeks.org/category/guestblogs/" ``` The command will save the screenshot to a folder titled "screenshots". You may also save the screenshot to a specific location by specifying the output directory using the `-o` option: ``` rustywitness -o ./screenshots "https://www.geeksforgeeks.org/category/guestblogs/" ``` ![Screenshot captured with rustywitness](/content/website-screenshots-command-line/pU2VySx.png) rustywitness is simple to use, but has far fewer options than the other examples in this article. This makes rustywitness easier to incorporate into your workflow, since there are no libraries to load or programming environments to manage. rustywitness worked very well during testing for this article, with no issues gathering screenshots from the example code above. However, rustywitness is a young project, so you may encounter the occasional bug. Additionally, many options provided by tools like gowitness are not available in rustywitness, despite the similar names. For example, rustywitness doesn't allow you to specify dimensions for your captured image, focus on specific selectors, or add a delay before capturing the screenshot. It also doesn't offer the ability to dismiss banners or pop-ups. This means that if you need more control over the screenshots, rustywitness may not be flexible enough for your workflow. ## Taking Screenshots with Urlbox [Urlbox](https://urlbox.com/.md) is a tool that allows you to capture perfect screenshots and PDF documents from any URL or HTML. Urlbox has options for capturing full-page screenshots using the [screenshot API](https://urlbox.com/screenshot-api.md), and captures responsive screenshots by allowing you to change the viewport dimensions. Additionally, Urlbox has web font and emoji support, ensuring that the images you capture will appear exactly as they would if you were to visit the page directly. Best of all, Urlbox works at scale, providing you with the ability to capture accurate screenshots on sites using the most recent JavaScript, HTML, and CSS features. Getting started is nearly instant—just sign up and you are ready to capture screenshots of any URL. If you just want to see how your HTML is rendered, you can also use Urlbox to render images from arbitrary HTML with a unified, easy-to-use dashboard. Urlbox provides many useful options that allow you to capture just the viewport of the loaded URL, capture a specific element, and select the output format from a range of supported formats, including JPG, PNG, and PDF. Urlbox saves you headaches by allowing you to capture images without writing a single line of code, but if you want to flex your programming chops, you have the option to add custom JavaScript or CSS to manipulate the rendered image. You can even incorporate Urlbox into your Node or Python project if your screenshots are a part of a larger application or process. For more information about options, use cases, and integrating Urlbox into your project, visit the [Urlbox docs](https://urlbox.com/docs/.md). ### Urlbox Examples Urlbox offers a fully featured dashboard, and you can access the Urlbox API using simple `curl` commands. Before you can make any requests to the Urlbox API, you need to create an account and retrieve your API key from the Urlbox dashboard. After grabbing your key from the dashboard, create a project folder and navigate to this folder in your terminal . Finally, copy the code below and paste it into a file called `urlbox.bash`. The examples below will use this script. The examples below will all use the following script: ```bash #!/usr/bin/env bash api_key=<YOUR_API_KEY_HERE> api="https://api.urlbox.com/v1/${api_key}/png" url="$1" filename="$2" composed_url="${api}?url=${url}" curl --silent "${composed_url}" --output "${filename}" ``` Capturing a basic screenshot using curl and Urlbox can be done using the following command: ``` bash urlbox.bash "https://www.geeksforgeeks.org/category/guestblogs/" "guestblogs.png" ``` The command above produces the following image: ![Basic screenshot with Urlbox](/content/website-screenshots-command-line/aDO2wzT.png) Unlike some options, the site is fully loaded, which is a good start. The down side of this is that there's an ad at the top of the page, and a banner at the bottom. Urlbox offers the ability to easily remove both of these elements with the `block_ads` and `hide_cookie_banners` options: ``` bash urlbox.bash "https://www.geeksforgeeks.org/category/guestblogs/&block_ads=true&hide_cookie_banners=true" "guestblogsclean.png" ``` ![Urlbox screenshot blocking ads and dismissing cookie banners](/content/website-screenshots-command-line/aybHnBc.png) Urlbox also allows you to quickly and easily make much more extensive customizations to your screenshots. You can specify the size of the viewport to simulate a larger or smaller screen, capture specific selectors, highlight a word or words, or scroll to a specified point on the page before capturing the image. You can also customize the output of the screenshot, such as requesting a retina-quality image, or saving to different formats, such as PDF, HTML, SVG, and JPG. Urlbox is a complete, highly customizable solution for capturing images from URLS or raw HTML, resolving all of the issues that arise when using other tools. You also don't have to write a single line of code with Urlbox, which lets you get started immediately—without the overhead of setting up a Python or Node project, or installing anything else on your machine. ## Conclusion In this article you learned about several methods for capturing images from URLs on the command line. You've also seen how Urlbox can solve some common issues with these solutions by providing an all-in-one platform where you can get started capturing images quickly. Finally, you learned that Urlbox can grow with your project, letting you use the request URL and JSON options in your own projects, either on the command line or alongside other automation tools. [Start capturing screenshots](https://urlbox.com/.md) now with Urlbox. --- # How to Take Screenshots in Django > In this article, you will explore several ways of automating screenshot capturing using Django, along with code implementation for each method. Source: https://urlbox.com/website-screenshots-django Last updated: 2022-10-31 --- There are many reasons why you would want to take screenshots. Suppose you want to demonstrate how to use a specific application to your users; rather than writing a lengthy document that might be prone to being misunderstood, you can take screenshots and highlight each step using text on the screenshots. You can also take screenshots of your application at different stages during development. This process can be automated to make it more efficient. You can also take screenshots of page content and make it shareable as opposed to sending links. This tutorial will demonstrate how to take screenshots with Urlbox in a django application using the urlbox django package available [here](https://pypi.org/project/urlbox/). We will also explore other alternative packages available for taking screenshots with Django Urlbox is an API that allows you to render screenshots from URLs and HTML and manipulate them as best suited. Screenshots are rendered as PNG or PDF documents. Urlbox does this through a simple GET synchronous API GET request which would look like this : ```python import requests response = requests.get("https://api.urlbox.com/v1/api-key/format?options") ``` Where options will be the url and any other customization you would want, for example, to get a full-page screenshot of [https://youtube.com](https://youtube.com)with a width of 800, the resulting request would look like this: ```python import requests response = requests.get("https://api.urlbox.com/v1/api_key/png?url=youtube.com&thumb_width=800") with open("image.png", "wb") as f: f.write(response.content) ``` The resulting screenshot will look like this: ![image9](/content/website-screenshots-django/image9.png) We will create a simple application that allows users to supply a url, and by clicking a button, the user will get a perfect screenshot captured by the [Urlbox API](https://urlbox.com/.md). The application will look like this: ![image11](/content/website-screenshots-django/image11.png) ## Project Setup We will start by creating a root folder that will house all our project files. Create a folder called `Screenshots` in your preferred location. ```sh mkdir Screenshots ``` Ensure you have a virtual environment setup and django installed. Next, create a new Django project named `django_screenshot`. ```sh django-admin startproject django_screenshot ``` ### Create a django app Create a django app called `screenshot` in the root `django_screenshots` directory. ```sh python manage.py startapp screenshot ``` Next, add the app screenshot to the list of installed\_apps in the `settings.py` file. ```python INSTALLED_APPS = [ 'screenshot', # add here ] ``` Create a new file `urls.py` in the screenshot directory and add the code below. ```python from django.urls import path urlpatterns = [ ] ``` Open the root urls.py file and modify it to include the screenshot app url configurations ```python from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path(' ', include('screenshot.urls')), ] ``` When a user submits a url, urlbox will generate a screenshot of the submitted url. Since we will deal with media files, we will use the default [FileSystemStorage](https://docs.djangoproject.com/en/4.0/ref/files/storage/#django.core.files.storage.FileSystemStorage) provided by Django. Add the necessary configurations for FileSystemStorage in the settings.py file. ```python MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') ``` MEDIA\_ROOT Is the file system path where media files are stored, while MEDIA\_URL is the url for serving files stored in MEDIA\_ROOT. By default, during development, Django does not serve media files; to ensure we can serve the files from MEDIA\_ROOT in development, add the following to the project `urls.py` file. ```python urlpatterns = [ path('admin/', admin.site.urls), path(' ', include('screenshot.urls')), ]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) # new ``` Open the `models.py` file and define the following database fields. ```python class Screenshot(models.Model): url = models.CharField(max_length = 100 , blank = False,null = False) photo = models.ImageField( upload_to='images' ) ``` The `ImageField` requires the [Pillow](https://pillow.readthedocs.io/en/stable/) library ,to install Pillow; issue the following command. ```sh pip install Pillow ``` Create and apply migrations ```sh python manage.py makemigrations python manage.py migrate ``` ## Urlbox API To use the urlbox API, register for a free trial account with Urlbox [here](https://urlbox.com/pricing.md). ![image8](/content/website-screenshots-django/image8.png) After you register an account, you will get a confirmation email. Once you confirm your email, login to your urlbox account to obtain the api key and Api secret key. ![image5](/content/website-screenshots-django/image5.png) Please take note of your API keys, as we will use them to grant access when taking screenshots. Next, install the urlbox [package](https://pypi.org/project/urlbox/) with pip. ```sh pip install urlbox ``` Next, go to the `settings.py` file and add the urlbox API\_KEY and API\_SECRET keys. ```python API_KEY='your_urlbox_API_KEY' API_SECRET='your_urlbox__API_SECRET_KEY' ``` ### Take Screenshots UI Page The first step is to create the view that will render the browser's screenshots page. Open views.py and create a function view that renders the template page. ```python from django.shortcuts import render # Create your views here. def index(request): return render(request, 'screenshot/index.html') ``` By default, django will look for templates in the template directory of the django app. Let's go ahead and create the ` index.html file`. In the screenshot folder, create a folder called `templates`; inside the templates folder, create another folder with the same name as the django app, i.e., `screenshot`. Inside the inner screenshot folder, create a file called `index.html`. The directory structure should look like this: ``` screenshot/ templates/ screenshot/ -index.html ``` Inside the `index.html` file, we will add a form that accepts a POST method, and inside the form, we will have an input field that will pass data to the view. Add the following code to index.html. ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <title>Take Screenshots
{% csrf_token %}
``` Next, hook the view to a url, Open `screenshot/urls.py` file and add the route for serving the index view. ```python from django.urls import path from .views import index urlpatterns = [ path('', index, name = 'index'), ] ``` Start the development server again and navigate to the index page. You should see something like this. ![image11](/content/website-screenshots-django/image11.png) Our UI is complete; let's proceed to add the logic for taking a screenshot with the Urlbox API. Open views.py and start by adding the necessary imports ```python from urlbox import UrlboxClient from .models import Screenshot from django.core.files.base import ContentFile from django.conf import settings ``` Next update the index view as follows. ```python def index(request): if request.method == 'POST': user_url = request.POST['url'] urlbox_client = UrlboxClient(api_key=settings. API_KEY, api_secret= settings.API_SECRET) response = urlbox_client.get({"url": user_url}) myfile = ContentFile(response.content) screenshot_instance = Screenshot(url = user_url) screenshot_instance.photo.save('image.png',myfile ) return render(request, 'screenshot/index.html', {'img':screenshot_instance}) return render(request, 'screenshot/index.html') ``` In the index function above, if the request method is `POST`, we do the following: - `user_url = request.POST['url']` - fetches the url submitted by the user - `urlbox_client = UrlboxClient(api_key=settings. API_KEY, api_secret= settings.API_SECRET)` - initialises the UrlboxClient - `response = urlbox_client.get({"url": user_url})` - makes a request to the Urlbox API with a url as a parameter - `myfile = ContentFile(response.content)` - saves the content of the response(binary screenshot data) to a ContentFile object - `screenshot_instance = Screenshot(url = user_url)` - creates a Screenshot model instance with a url attribute - `screenshot_instance.photo.save('image.png',myfile )` - saves the screenshot\_instance to the database as a file - `return render(request, 'screenshot/index.html', {'img':screenshot_instance})` - serves the index page and passes the saved screenshot\_instance to the template. **The Urlbox API might take some time to return the screenshot; therefore, in production, it's advisable to perform the API call in the background and display a waiting message to the user.** Once the user submits the url, we also return a response containing the captured screenshot. Update the `index.html` page and pass the `screenshot_instance` variable as follows. ```html
``` Here is a screenshot captured. ![image13](/content/website-screenshots-django/image13.png) Urlbox also gives you more options to customize your screenshots; for example, you can customize the image format and size of the image by adding additional options to the API. For example, if you need to get a full-page screenshot in the webp format, your API will look like this: ```python response = urlbox_client.get({"url": user_url,"full_page": True,"format":"webp"}) ``` Here is a full-page screenshot in jpg format ![image6](/content/website-screenshots-django/image6.jpg) ### Blocking ads and banners Suppose you need to take a screenshot from a url that contains ads or banners. Urlbox allows you to add an Adblock filter. For example, here is a screenshot of a url that has a lot of ads. ![image12](/content/website-screenshots-django/image12.png) Let's test the same url with Urlbox,Update the API call as follows: ```python response = urlbox_client.get({"url": user_url,"block_ads": True}) ``` Below is the output of the same page with ads blocked using Urlbox API ![image1](/content/website-screenshots-django/image1.png) As you can see, Urlbox automatically block ads from appearing in your screenshots and hides any cookie banners as well ### How to save media files on Amazon S3 Urlbox also provides the option to save your media files on Amazon Simple Storage Service . To do that, you need to have an [Amazon S3](https://aws.amazon.com) account, sign up for S3 storage and create an Amazon S3 bucket. Once you create an Amazon S3 bucket, assign a user and you should obtain an Access Key ID and a secret Access key. Next, login to your Urlbox account and setup S3 configurations as shown below ![image10](/content/website-screenshots-django/image10.png) Once that is setup, Urlbox will automatically render your files directly to an S3 bucket. ### Advantages of using Urlbox Urlbox is easy to set up and doesn't require a lot of configurations. The API is straightforward and gives you many options for customizing your screenshots. Urlbox also offers good-quality screenshots and the ability to automate website screenshots on a schedule. You can also set the image quality and produce images with transparent and dark mode backgrounds, among other excellent [features](https://urlbox.com/docs/options.md#). ## Alternatives to Urlbox Urlbox offers alot of features , however there are still other alternatives for taking screenshots with Django such as: - Pyautogui - HTML2Image - Pillow ### pyautoguimodule [pyautogui](https://pyautogui.readthedocs.io/en/latest/) is a Python automation module that allows you to perform certain functions such as taking screenshots, locating an application window, displaying alert and message boxes, e.t.c Using the screenshot app we created above, we will demonstrate how to take screenshots with the pyautoguimodule To use the pyautogui module, we first need to install it using pip. ```sh pip install pyautogui ``` You will aslo need to have the Pillow library installed. If you are using linux, install the `crot` command as well. ```sh sudo apt-get install scrot ``` Next, create a take\_screenshot view function in `views.py` and add the code below. ```python import io import pyautogui from django.core.files.base import ContentFile def take_page_screenshot(request): screenshot = pyautogui.screenshot() image_byte_obj = io.BytesIO() screenshot.save(image_byte_obj, 'PNG') byte_img = image_byte_obj.getvalue() image_instance = Screenshot() image_instance.photo.save('img.png', ContentFile(byte_img) ) return redirect("/") ``` The code above does the following: - `screenshot = pyautogui.screenshot()` - takes a screenshot of the current screen and returns an image in Pillow `PngImageFile` format . - `image_byte_obj = io.BytesIO()` - creates a `BytesIO` object. - `screenshot.save(image_byte_obj, 'PNG')` - Saves the Pillow image in memory as a bytes-like object. - `byte_img = image_byte_obj.getvalue()` - gets the value of the image bytes object. - `image_instance = Screenshot()` - Creates a Screenshot model instance. - `image_instance.photo.save('img.png', ContentFile(byte_img) )` - converts the bytes image object to File format and saves it to the file directory specified in settings.py file. Hook the view to the urls.py file. ```python from .views import take_page_screenshot urlpatterns = [ path(page, take_page_screenshot, name = page), ] ``` If you run the endpoint, (at http\://127.0.0.1:8000/page) it will generate the screenshot below. ![image2](/content/website-screenshots-django/image2.jpg) A major drawback of taking screenshots with pyautogui is that it doesn't allow you to specify a particular width or height.It does not block any ads or banners, and you will also be required to perform other tasks, such as cropping out the intended image. Pyautogui is also limited to the current screen and will not take screenshots of a particular Url. It also doesn't give you the option to customize your screenshots. For example, if you need to take a full-page screenshot of the app you are building to showcase its features, pyautogui can't do that since it's restricted to the current page. Another drawback of using pyautogui is that it relies on a GUI to take screenshots and therefore is not a reliable way to take screenshots in a production environment. ### HTML2Image [html2image](https://pypi.org/project/html2image/) is a lightweight python package that provides a wrapper around the [headless mode](https://developer.chrome.com/blog/headless-chrome/) of most browsers by converting urls to screenshots. Issue the following command to install html2image. ```sh pip install html2image ``` Next, open views.py file and add the following code. ```python from html2image import Html2Image from django.core.files.base import File def html_to_image(request): hti = Html2Image(size = ( ) img =hti.screenshot(url='https://urlbox.com/', save_as='img.png') image_instance = Screenshot() image_instance.photo.save('image.png', File(open(img[0], 'rb')) ) return redirect("/") ``` The code above does the following: - `from html2image import Html2Image` - imports the html2image module - `hti = Html2Image()` - creates an instance of the html2image module - ` img =hti.screenshot(url='https://urlbox.com/', save_as='img.png')` - use the `screenshot` method of the html2image module to take a screenshot of the specified url and returns the path to the screenshot. - ` image_instance = Screenshot()` creates a Screenshot model instance - ` image_instance.photo.save('image.png', File(open(img[0], 'rb')) )` - saves the captured screenshot as an image file to the media folder specified in `settings.py` file Here is the resulting screenshot. ![image3](/content/website-screenshots-django/image3.png) HTML2Image also allows you to set the size of the screenshot, for example, if you need a custom size, you would specify it as follows, ```python hti = Html2Image(size = (850,400)) ``` **HTML2Image only supports the chrome browser at the moment** ### Pillow [Pillow](https://pillow.readthedocs.io/en/stable/) is an imaging library that adds image-processing capabilities to your Python interpreter. Pillow provides the ImageGrab module, which grabs the contents of a screen and saves it in `PngImageFile` format. Ensure you have Pillow installed Update views.py as follows: ```python from PIL import ImageGrab def take_screenshot(request): screenshot = ImageGrab.grab(bbox = None) image_byte_obj = io.BytesIO() screenshot.save(image_byte_obj, 'PNG') byte_img = image_byte_obj.getvalue() image_instance = Screenshot() image_instance.photo.save('image.png', ContentFile(byte_img) ) return redirect("/") ``` The code above does the following: We first import the `ImageGrab` module from Pillow, then use the `grab()` method to take a screenshot of the current screen. The resulting PIL image is then converted to a bytes-like object and saved to the file directory specified in the settings.py file. Here is the captured screenshot. ![image4](/content/website-screenshots-django/image4.png) If you need to grab a certain part of the screen, you can specify as follows: ```python screenshot = ImageGrab.grab(bbox = (0, 0, 1200, 1000)) ``` Here is the customized sized screenshot. ![image7](/content/website-screenshots-django/image7.png) If you have multiple screens, you can capture them as follows: ```python screenshot = ImageGrab.grab(all_screens=True) ``` **Multiple screens option is, however, only supported in windows.** ## Conclusion This tutorial covered how to take screenshots with the Urlbox API and explored other options such as Pillow, pyautogui, and HTML2Image. Now you have great options for taking screenshots of your Django application. --- # How to Add Website Screenshots to a Laravel Application > In this article, you will explore several ways of automating screenshot capturing using Laravel, along with code implementation for each method. Source: https://urlbox.com/website-screenshots-laravel Last updated: 2022-09-22 --- There are many reasons that you might need to capture screenshots programmatically in a Laravel application, but as a Laravel developer, your options can be limited, especially if you'd prefer not to rely on extensive JavaScript. The most common way of programmatically capturing screenshots is using JavaScript code to control a web browser instance in the background, but using JavaScript to capture website screenshots in your Laravel application comes with its drawbacks. For many developers, there will be a learning curve. It also requires that you code and maintain a Node.js package. There are Laravel alternatives that you can use in your application to help you code faster and cut the development and maintenance time. In this article, you will explore several ways of automating screenshot capturing using Laravel, along with code implementation for each method. You'll look at screenshots taken using each of these methods to get a better idea of their pros and cons. ## Use Cases There are a number of use cases in which you might need to automate screenshot capturing within your Laravel application. The whole application can be wrapped around this feature or it can be one of the many features that your application offers. Examples of common use cases include: - Allowing users of a social network to share links with on-demand, automated thumbnail capturing. - Developing features that allows users to take screenshots of their app activity to share on social media. - Building an online directory or archive that requires the availability of constantly updated website homepage images. - Taking screenshots in a web-based staff management system for reporting purposes. - Generating screenshots for testing. ## Setup To follow up with the following examples, you need to have PHP 8.0+ and [Composer](https://getcomposer.org/download/) installed on your testing machine. With these installed, navigate in your terminal window to the folder in which you would like to create a project. Create the project using the following command: ```bash composer create-project laravel/laravel screenshots-with-laravel ``` Wait a few seconds for the project to be created, then navigate to the newly created project folder and you will be ready to follow up with the tutorial. ## Taking Screenshots Using a Node.js Package Wrapper Coding and maintaining a wrapper package to cover all the features of a Node.js package is a time-consuming task. To avoid having to write JavaScript code, this example will use the [Browsershot PHP](https://spatie.be/docs/browsershot/v2/introduction) package. Browsershot is a PHP wrapper package for the commonly used Node.js package [Puppeteer](https://pptr.dev/). Puppeteer provides a JavaScript API that controls a Chrome browser in headless mode. Install the Browsershot package with the following command: ```bash composer require spatie/browsershot ``` Since Browsershot uses Puppeteer behind the scenes, you need to have [Node.js](https://nodejs.org/en/download/) and [NPM](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) installed on your machine. You also need to install Puppeteer by running the following command: ```bash npm i puppeteer --save ``` Next, you'll create the controller: ``` php artisan make:controller BrowsershotController ``` The controller will be created inside your project folder at the path `app/Http/Controllers//BrowsershotController.php`. Open the controller file and add the following code at the top to import the Browsershot package: ``` use Spatie\Browsershot\Browsershot; ``` After adding the previous code, create a method in the controller class to include the logic of taking screenshots using Browsershot: ``` function screenshotTest() { Browsershot::url('https://www.nytimes.com/') ->setOption('landscape', true) ->windowSize(1600, 1024) ->waitUntilNetworkIdle() ->save(storage_path() . '/laravel_screenshot_browsershot.png'); } ``` Browsershot offers a number of options, of which five are being used to take the screenshot: - `Browsershot::url('https://www.nytimes.com/')` is used to set the URL to be screenshotted. - `->setOption('landscape', true)` sets the page orientation as landscape. - `->windowSize(3840, 2160` sets the window size. - `->waitUntilNetworkIdle()->waitUntilNetworkIdle()` waits for the network activity to stop so you ensure that all the resources are loaded. - `->save(storage_path() . '/laravel_screenshot_browsershot.png')` sets the path where the image will be saved on your server. In whole, the controller will look like this: ``` setOption('landscape', true) ->windowSize(3840, 2160) ->waitUntilNetworkIdle() ->save(storage_path() . '/demo_laravel_screenshot2.png'); } } ``` Add a new route to the `routes/web.php` file: ``` Route::get('/test-screenshot-with-browsershot', 'App\Http\Controllers\BrowsershotController@screenshotTest'); ``` Now, run the local development server with Laravel CLI: ```bash php artisan serve ``` Finally, open the page on your browser to test the function: ``` http://127.0.0.1:8000/test-screenshot-with-browsershot ``` ![A screenshot captured using Browsershot in Laravel](/content/website-screenshots-laravel/0Z0MUip.png) The quality of the image is acceptable. However, you can see that though the ad itself hadn't yet loaded when the capture was taken, the top ad banner covers a large area of the image. Browsershot relies on the Puppeteer Node.js package as a dependency. This adds a new layer of maintenance, since your Node.js version and the Puppeteer package need to be always up to date. One major drawback of this method is that the screenshot capturing code runs on your server. This may not be a big deal if the screenshot feature isn't used often, or is only used for testing purposes. However, if your application relies heavily on this feature, using Browsershot as a dependency can take up a lot of your machine resources. In many cases, developers end up creating a microservice to handle the image capturing operations. ## Taking Screenshots Using PHP-Chrome PHP-Chrome is a PHP package that allows you to programmatically control a Chrome/Chromium instance in headless mode. This eliminates the need to rely on a Node.js dependency. You can build on the same project that was created earlier, in the setup section. Navigate to the project folder in your terminal window, and run this command: ```bash composer require chrome-php/chrome ``` Create a new controller to execute the screenshot capturing using Chrome-PHP: ``` php artisan make:controller PHPChromeController ``` The controller will be created at the path `app/Http/Controllers//PHPChromeController.php`. Open this file and add the following code to import the PHP-Chrome package: ``` use HeadlessChromium\BrowserFactory; ``` Open the controller file at `app/Http/Controllers//PhpChromeController.php` and add the following code before the controller class to import the PHP-Chrome package: ``` use HeadlessChromium\BrowserFactory; ``` Create a method in the PhpChromeController class that includes the logic to take a screenshot using PHP-Chrome: ``` function ScreenshotTest() { $browserFactory = new BrowserFactory(); $browser = $browserFactory->createBrowser(['windowSize' => [1920, 1000]]); try { $page = $browser->createPage(); $page->navigate('https://www.bbc.co.uk/')->waitForNavigation(); $page->screenshot()->saveToFile(storage_path() . '/php_chrome_screenshot.png'); } finally { $browser->close(); } } ``` The function uses the following steps to capture a screenshot: - `$browserFactory = new BrowserFactory()` creates an instance of the Chrome browser. This might not work on a production server which adds the requirement of installing a Chromium browser. - \`$browser = $browserFactory->createBrowser(\['windowSize' => \[1920, 1000]]) creates the browser and sets the window size. - `$page->navigate('https://www.bbc.co.uk/')->waitForNavigation()` navigates to the requested page and waits for the network activity to stop. - `$page->screenshot()->saveToFile(storage_path() . '/php_chrome_screenshot.png')` takes the screenshot and sets the path to save the image. When you're done, the controller should look like this: ``` createBrowser(['windowSize' => [1920, 1000]]); try { $page = $browser->createPage(); $page->navigate('https://www.bbc.co.uk/')->waitForNavigation(); $page->screenshot()->saveToFile(storage_path() . '/php_chrome_screenshot.png'); } finally { $browser->close(); } } } ``` Add the following route to the `routes/web.php` file: ``` Route::get('/test-screenshot-with-php-chrome', 'App\Http\Controllers\PhpChromeController@ScreenshotTest'); ``` Now you can run the local development server with Laravel CLI: ```bash php artisan serve ``` Open `http://127.0.0.1:8000/test-screenshot-with-php-chrome` in your browser to test the function. ![A screenshot captured using PHP-Chrome in Laravel](/content/website-screenshots-laravel/VvpDO5I.png) Using Chrome-PHP eliminated the need to rely on Node.js dependencies for screenshot capturing. However, you will still run the image capturing process on your server by controlling a browser. As before, there are ads taking up a substantial portion of the screen real estate, and if you'd like to dismiss banners or pop-ups, you'll need to learn how to programmatically control a Chrome/Chromium browser, which may have a steep learning curve. ## Taking Screenshots With Laravel Dusk [Laravel Dusk](https://laravel.com/docs/9.x/dusk) is an official browser automation testing package developed and maintained by Laravel. It is a powerful testing tool that can be used to take screenshots by controlling a headless version of the Chrome browser. Run the following command to add the Laravel Dusk package as a dependency: ```bash composer require --dev laravel/dusk ``` Once the dependency is added, you can install Laravel Dusk to your project by running this Artisan command: ```bash php artisan dusk:install ``` This command creates a folder called Browser in your tests directory. Inside the Browser folder, you'll find the screenshots folder, where the screenshots taken by Laravel Dusk are saved, and an example class created by the dusk:install command. Open the file `ExampleTest.php` inside the `tests/Browser` folder. An example test named `testBasicExample()` is already created inside the exampleTest class. Edit this method to look like this: ``` public function testBasicExample() { $this->browse(function (Browser $browser) { $browser->visit('https://www.howtogeek.com/') ->screenshot('home-page-screen-test'); }); } ``` When you're done, the class will look like this: ``` browse(function (Browser $browser) { $browser->visit('https://www.howtogeek.com/') ->screenshot('home-page-screen-test'); }); } } ``` In this function, you've used two of the [many options](https://laravel.com/docs/9.x/dusk) that Laravel Dusk offers: - `$browser->visit('https://www.howtogeek.com/')` sets the URL you’ll take a screenshot of. - `->screenshot('home-page-screen-test')` sets the image file name. Run the local development server with Laravel CLI: ```bash php artisan serve ``` Run the Laravel Dusk test command: ``` php artisan dusk ``` ![A screenshot captured using Laravel Dusk](/content/website-screenshots-laravel/1tVnlQm.png) Laravel Dusk provides a great way to take screenshots for browser automation testing. It can automatically create tests for your application routes, create multiple browsers, interact with forms, test authentication and, of course, take screenshots. However, because capturing screenshots of external websites isn’t the use case it was created for, Dusk won’t help with ad blocking or pop-up blocking, as you can see in the screenshot captured. It is not recommended to use Laravel Dusk for any purpose other than testing. Using Dusk in production environments can compromise your application's security, because it will allow anyone to log in through the routes created for the authentication testing. This explains why the package was installed as a "--dev" dependency earlier in this example. ## Taking Screenshots with Urlbox Urlbox provides a powerful API to take screenshots on both testing and production servers. In addition to the regular screenshot capturing feature, Urlbox provides a [webhook](https://urlbox.com/docs/webhooks.md) feature that allows your application to capture a large number of screenshots asynchronously, then receive a notification a screenshot is rendered. To get started, [sign up](https://urlbox.com/pricing/.md) for a free trial to obtain an API key and API secret. After logging in, you will find the API and Secret keys that you will use in your account dashboard. ![Urlbox dashboard](/content/website-screenshots-laravel/hSOCcwS.png) Install the package with the following command: ```bash composer require urlbox/screenshots ``` Add your Urlbox API key and API secret key to the `.env` file: ``` URLBOX_API_KEY=ADD-YOUR-API-KEY-HERE URLBOX_API_SECRET=ADD-YOUR-API-SECRET-HERE ``` Replace ADD-YOUR-API-KEY-HERE with your API key and ADD-YOUR-API-SECRET-HERE with your API secret. Create the controller: ``` php artisan make:controller UrlBoxController ``` Open the controller file that you've just created at the path `app/Http/Controllers//UrlBoxController.php` and add the following code before the class. ``` use Urlbox\Screenshots\Urlbox use Illuminate\Support\Facades\Storage; ``` The first line of this code imports the Urlbox package, and the second line imports the Laravel storage driver so you can save the image to the local storage. Create the function that will contain the logic of taking a screenshot using Urlbox: ``` function ScreenshotTest() { $urlbox = Urlbox::fromCredentials(env('URLBOX_API_KEY'), env('URLBOX_API_SECRET')); $options['url'] = 'https://www.bbc.co.uk/'; $options['width'] = 1920; $options['block_ads'] = true; $options['hide_cookie_banners'] = true; $urlboxUrl = $urlbox->generateSignedUrl($options); echo 'Test screenshot generated by Urlbox'; $image_file = file_get_contents($urlboxUrl); Storage::disk('local')->put('screenshot_with_urlbox.png', $image_file); } ``` The function uses the following steps to capture a screenshot: - `$urlbox = Urlbox::fromCredentials(env('URLBOX_API_KEY'), env('URLBOX_API_SECRET'))` adds the API key and secret credentials that you previously added to the `.env` file for API authentication. - ` $options['url'] = 'https://www.bbc.co.uk/'` sets the URL that you would like to capture. The URL option is the only required parameter for the API request to work. If you ignore the following options, the API request will still run. - `$options['width'] = 1920` sets the screen width to 320 pixels. - `$options['block_ads'] = true` blocks the ads displayed on the page to capture. - `$options['hide_cookie_banners'] = true` hides the cookie banners. - `$urlboxUrl = $urlbox->generateSignedUrl($options)` generates the API request URL. - `echo 'Test screenshot generated by Urlbox'` wraps the image captured by Urlbox in an HTML `` tag and displays it. - `$image_file = file_get_contents($urlboxUrl) Storage::disk('local')->put('screenshot_with_urlbox.png', $image_file)` gets the image file and saves it to your storage. The controller should look like this: ``` generateSignedUrl($options); echo 'Test screenshot generated by Urlbox'; $image_file = file_get_contents($urlboxUrl); Storage::disk('local')->put('screenshot_with_urlbox.png', $image_file); } } ``` Add a new route to the routes/web.php file: ``` Route::get('/test-screenshot-with-urlbox', 'App\Http\Controllers\UrlBoxController@ScreenshotTest'); ``` Run the local development server with Laravel CLI: ```bash php artisan serve ``` Open a browser window and open `http://127.0.0.1:8000/test-screenshot-with-urlbox` to test the function: Once the image is rendered, you will have an image file saved on your server, and another image saved in the cloud by Urlbox. The locally saved screenshot image file will be at the `storage/app` folder, and the URL generated by Urlbox will be in this format: ``` https://api.urlbox.com/v1/API_KEY/TOKEN/png?url=website-url.com ``` ![A screenshot captured using Urlbox in Laravel](/content/website-screenshots-laravel/0oB7kDA.png) As you can see, this example is a clean, uncluttered screenshot. In this example, you've used relatively minimal options to generate the screenshot, but there are many other [Urlbox options](https://urlbox.com/docs/options.md) available. These include capturing high-DPI retina images, capturing a full page, hiding cookie banners, and automatically clicking buttons to dismiss pop-ups. By using Urlbox in the previous example, you didn’t have to install a Node.js package or configure and control a browser to handle the operation of capturing the screenshot. This saves much of the precious development and maintenance time. It also saves the infrastructure cost that comes with the heavy use of the screenshot capturing function you are developing. ## Conclusion Adding automated screenshot capturing to a Laravel application can be done in many ways, mostly by using Node.js code or using a PHP package that acts as a wrapper for a Node.js package. The most commonly used Node.js package is Puppeteer. Another way is to use a PHP library that provides an API to control a Chromium browser. Finally, using Urlbox API provides the most straightforward way to take screenshots with no need to maintain dependencies or control a browser instance. [Urlbox API](https://urlbox.com/screenshot-api/php.md) is the most efficient way to automate screenshot capturing. It eliminates the need to code in JavaScript, rely on a long list of dependencies, or control any Chrome browser installations. It provides a simple API loaded with features like ad-blocking, pop-up blocking, and cookie banner blocking. By using Urlbox, screenshot capturing can be scaled and run asynchronously. The options for storing images are also expanded. You can either use the images immediately, save them to your local server, or configure S3 storage to store images captured by asynchronous requests and use webhooks to get your application notified once a screenshot is rendered. --- # How to Take a Screenshot of a Website Using PHP > We'll look at four different ways in which you can produce high-quality captures, including methods which require no JavaScript knowledge Source: https://urlbox.com/website-screenshots-php Last updated: 2022-06-17 --- Programmatic screenshot captures are often used to automate social media campaigns and produce directories of website content. Using a screenshot is more reliable than downloading a copy of the website's HTML, CSS, and JavaScript. You get to see the page's visuals as they were at the time of the capture, without being dependent on third-party embeds remaining live on the internet. There are many different ways to generate screenshot captures yourself. Most techniques rely on some knowledge of JavaScript. Web browsers execute JavaScript code, and their remote control mechanisms rely on JavaScript interfaces. This complicates matters for backend developers who may be inexperienced with directly controlling a browser. In this article, we're focusing on capturing screenshots from the perspective of a [PHP developer](https://www.toptal.com/php). We'll look at four different ways in which you can produce high-quality captures, including methods which require no JavaScript knowledge. All the sample code shown below is available in this article’s [GitHub repository](https://github.com/ilmiont/urlbox-php-demo). ## Use Cases Screenshot generation that's initiated by a PHP application can have several roles in an application. It's most common to find the process integrated into automated workflows that need to store web content for the future. Screenshot captures can take several seconds to complete. You might have a requirement that new URLs added to your database are captured in a background task. Having your PHP backend initiate the capture lets users continue their work elsewhere while the screenshot is queued, produced, and uploaded to your storage provider. Alternatively, you might need to integrate screenshots with an existing PHP application. When you're using a content management system [such as WordPress](https://github.com/urlbox/wordpress-screenshots), sticking with PHP to capture screenshots can flatten the learning curve and create a simpler management experience. ## Taking Screenshots Using a Separate Node.js Application The canonical approach is arguably to rely on a separate Node.js application that uses a project like [Puppeteer](https://github.com/puppeteer/puppeteer) to remotely control a Chrome web browser installation. You can interface between PHP and Node.js using PHP’s [`exec()`](https://www.php.net/manual/en/function.exec.php) or [`shell_exec()`](https://www.php.net/manual/en/function.shell-exec.php) functions. Make sure you've got [Chrome](https://www.google.com/chrome/), [Node.js](https://nodejs.org/en/), and [PHP](https://www.php.net/) installed on your host machine before you continue. You'll begin by creating the Node.js application that will be used to launch Chrome and initiate new captures. Save the following code as `screenshotWithPuppeteer.js`: ```javascript const puppeteer = require("puppeteer"); (async () => { const browser = await puppeteer.launch({ defaultViewport: { width: 1280, height: 720, }, }); const page = await browser.newPage(); await page.goto(process.argv[2]); await page.waitForTimeout(10); await page.screenshot({ path: process.argv[3] }); await browser.close(); })(); ``` This simple script starts Chrome, opens a new tab, and navigates to a URL. It then waits for ten seconds before capturing a screenshot. The delay helps ensure the page's content will have loaded completely. Use npm to install the `puppeteer` package before you run the program: ``` $ npm install puppeteer ``` Now you can capture a screenshot by supplying a URL and an output path to which the image will be saved: ``` $ node screenshotWithPuppeteer.js https://developers.google.com/web/tools/puppeteer puppeteer.png ``` Next you can write a PHP wrapper around your Node.js code: ```php ``` Now you can run your PHP script to capture your screenshot: ``` $ php screenshotWithPuppeteer.php ``` ![Screenshot of the Puppeteer website taken with a separate Node.js application](/content/website-screenshots-php/ol78i8f.png) This process works, but it's time-consuming to set up and maintain. It also bloats your environment with extra dependencies: you need Node.js and Puppeteer available before you can capture screenshots. Screenshot generation is only loosely integrated with your PHP application; it's dependent on `screenshot.js` being available, and your PHP code can’t directly influence the capturing behavior. Any future development will require modification of your Node.js code. The advantage of this option is the relative ease with which you can build advanced custom tooling around your solution. Puppeteer is one of the most complete browser automation solutions, giving you full control over your Chrome browser instance. Community extensions are available to add frequently used functionality such as [ad blocking](https://www.npmjs.com/package/puppeteer-extra-plugin-adblocker) and [tracker evasion](https://www.npmjs.com/package/puppeteer-extra-plugin-stealth). ## Taking Screenshots by Automating Chrome With Chrome-PHP [Chrome-PHP](https://packagist.org/packages/chrome-php/chrome) is a PHP package that provides Puppeteer-like control of Chromium browsers. Using this solution reduces your external dependencies to just Chrome or another compatible browser. Use Composer to add the package to your PHP project: ``` $ composer require chrome-php/chrome ``` Now you can write code that's similar to the Node.js example above, but without leaving PHP: ```php createBrowser(); $urlToCapture = "https://packagist.org/packages/chrome-php/chrome"; try { $page = $browser -> createPage(); $page -> setViewport(1280, 720); $page -> navigate($urlToCapture) -> waitForNavigation(); $screenshot = $page -> screenshot(); $screenshot -> saveToFile("captureWIthChrome.png"); } catch (\Exception $ex) { // Something went wrong } finally { $browser -> close(); } ?> ``` Save the file as `screenshotWithChrome.php`, then run it using PHP: ``` $ php screenshotWithChrome.php ``` ![Screenshot of the chrome-php/chrome Packagist page, captured with Chrome-PHP](/content/website-screenshots-php/wsjMtpd.png) Now the code is contained within your PHP application, making it accessible to developers without JavaScript experience. The Chrome-PHP API is fairly approachable and self-documenting, making it clear what each step achieves. The example above starts a Chrome instance on the host machine, then navigates to a URL, waits for it to load, and finally generates the screenshot. There's still significant complexity here, though. You need to understand the fundamentals of how Chromium remote control works, as Chrome-PHP is an abstract library that's not specifically focused on screenshots. You're responsible for establishing the correct procedure to produce the output that you need. Achieving common tasks like blocking ads and pop-ups is taxing, as you have to implement code from scratch. Identifying ad server domains to blacklist is notoriously time-consuming, requiring constant maintenance as distribution formats change. ## Taking Screenshots With Browsershot Spatie's [Browsershot](https://packagist.org/packages/spatie/browsershot) package has risen to prominence as one of the most popular methods of PHP screenshot generation. It's racked up over five million Packagist downloads. Browsershot relies on Puppeteer, so you must have Node.js and the Puppeteer package already available in your environment. Follow the instructions on the [Node.js website](https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions) to download the correct distribution for your platform, then use npm to globally install Puppeteer: ``` $ npm install -g puppeteer ``` This will make it accessible to Browsershot. Next, add the Browsershot package to your PHP project using Composer: ``` $ composer require spatie/browsershot ``` Browsershot is purpose-built to simplify screenshot generation. You can start capturing images using simple PHP code like this: ```php windowSize(1280, 720); $screenshot -> save("captureWIthBrowsershot.png"); ?> ``` Save the file as `screenshotWithBrowsershot.php`, then run your code to generate a screenshot: ``` $ php screenshotWithBrowsershot.php ``` ![Screenshot of the Browsershot homepage, captured with Browsershot](/content/website-screenshots-php/mqnEHdm.png) The Browsershot library wraps Puppeteer to automate the browser startup, navigation, and capture procedure that was implemented manually in the first two approaches. There are [several options](https://spatie.be/docs/browsershot/v2/introduction) that provide a degree of control over your screenshots. Here's a snippet that sets a larger viewport size, dismisses any pop-up JavaScript alerts, and adds a delay before the screenshot is taken: ```php windowSize(1920, 1080) -> dismissDialogs() -> setDelay(100) -> save("captureWIthBrowsershot.png"); ?> ``` The fluent API and clear focus on screenshots makes Browsershot easy to work with and maintain. However, the initial set up process is still rather convoluted. Browsershot relies on Node.js and Puppeteer, and makes you install both of them yourself. These dependencies will bloat your environment and demand regular upgrading as new releases arrive. ## Taking a Screenshot With Urlbox Urlbox is a different approach to any of the three options we've seen above. Urlbox operates a remote screenshot capturing service that you can access via an API. It offers retina-quality images with an extensive selection of options, including seamless ad blocking and full-page capturing. The service provides the capture infrastructure for you, drastically reducing the set up and maintenance overheads in your own environment. Urlbox is a paid service that offers a seven-day free trial. You'll need to [create an account](https://urlbox.com/pricing.md) before continuing with this section. Once you're logged in, you'll see your API key and API secret displayed in your account dashboard. These values will be needed below. ![Screenshot of the Urlbox dashboard showing API keys](/content/website-screenshots-php/aAEg17W.png) Begin your integration by adding Urlbox's official PHP SDK to your project. This abstracts interactions with the API, making it even easier to create screenshots from your project's code: ``` $ composer require urlbox/screenshots ``` You're now ready to add Urlbox to your PHP application. The following sample code will produce a URL that can be used to load a screenshot of a specific webpage: ```php generateSignedUrl([ "url" => $urlToCapture, "width" => 1280, "height" => 720 ]); echo "Screenshot of $urlToCapture" ?> ``` Save the file as `screenshotWithUrlBox.php`, then run it using PHP: ``` $ php screenshotWithUrlBox.php ``` Replace the `API_KEY` and `API_SECRET` placeholders with the values displayed in your Urlbox dashboard. The URLs returned by Urlbox's `generateSignedUrl()` method will look similar to this: ``` https://api.urlbox.com/v1/API_KEY/TOKEN/png?url=urlbox.com' ``` When you visit the URL, Urlbox provides the requested screenshot as an inline image that'll render within the `` tag. You can save the image to a file by requesting the URL via an HTTP library such as Guzzle. Add Guzzle to your project using Composer: ``` $ composer require guzzlehttp/guzzle ``` Then you can run the following code: ```php // $urlboxUrl = $urlbox -> generateSignedUrl(["url" => $urlToCapture]); (new \GuzzleHttp\Client()) -> request("GET", $urlboxUrl, ["sink" => "captureWithUrlBox.png"]); ``` Running the example will save a screenshot of the `$urlToCapture` URL to `captureWithUrlBox.png` in your working directory. ![Screenshot of the Urlbox website, captured using Urlbox](/content/website-screenshots-php/ixYRXjL.png) This approach solves the problems that cropped up repeatedly in the other solutions. Urlbox doesn't require JavaScript or a Chrome browser instance in your environment. This frees you up to keep writing PHP code without maintaining a companion Node.js application and Chrome installation. Urlbox also simplifies customized screenshot captures by providing several built-in options. As an example, here's how you can produce a retina-quality, full-page screenshot: ```php $urlboxUrl = $urlbox -> generateSignedUrl([ "url" => $urlToCapture, "width" => 1920, "height" => 1080, "retina" => true, "full_page" => true ]); ``` Urlbox's full-page screenshots are typically more accurate than those produced by a standard Puppeteer installation. The API incorporates unique measures to avoid common issues such as early cut-off, mid-page seams, and repeating sticky elements and scrollbars. Urlbox can take screenshots of specific elements within a page, too. Use the `selector` option to supply a [DOM selector](https://developer.mozilla.org/en-US/docs/Web/API/Document_object_model/Locating_DOM_elements_using_selectors) identifying the specific node you want to capture: ```php $urlboxUrl = $urlbox -> generateSignedUrl([ "url" => $urlToCapture, "selector" => "body > article section:first-child" ]); ``` You can view a complete list of supported options in the PHP SDK's [documentation](https://packagist.org/packages/urlbox/screenshots). Urlbox is also capable of blocking pop-ups, bypassing captchas, dismissing cookie banners, and loading webpages via a custom proxy server. These settings are configurable in your account dashboard, making them much easier to implement than with any of the other approaches shown above. Comprehensive ad blocking is only a few clicks away. In addition to direct integration with PHP applications, Urlbox provides its own [WordPress plug-in](https://github.com/urlbox/wordpress-screenshots). This lets you embed screenshots in your PHP websites using WordPress shortcodes. SDKs are available for Node.js, Ruby, Python, Java, and C#, as well. ## Conclusion Applications often rely on automated screenshot captures to archive, index, and share web-based content. However coding a programmatic capture system from scratch is often laborious and time-consuming, especially when you're integrating with a system that’s not already written in JavaScript. In this article, we've looked at four different ways in which PHP developers can handle screenshot captures. Out of these, maintaining your own Puppeteer installation is the most flexible, giving you complete control over the browser process. This is also the most complicated mechanism to set up and maintain. [Urlbox's PHP SDK](https://urlbox.com/screenshot-api/php.md) maximizes ease of use, letting you work entirely in PHP without learning JavaScript or Puppeteer's API. This provides a scalable way to generate screenshots on demand. It has clear [documentation](https://urlbox.com/docs.md) and a robust set of image capture options. --- # How to Take Screenshots with Ruby on Rails > We’ll show you 4 different ways to take website screenshots using Rails. Puppeteer & Goover, Cloudinary + URL2png, html2canvas and Urlbox. Source: https://urlbox.com/website-screenshots-rails Last updated: 2022-07-06 --- Rails developers often need to take screenshots within their programs for a variety of reasons. If you're a Rails developer, you may find yourself taking screenshots to: - Show a bug that's occurring during automated testing - Programmatically grab screenshots from a URL instead of asking your users to upload potentially inconsistent files - Track changes on your competitor’s pricing and landing pages - Ensure your i18n translations look great when accessed from their respective countries - And more... Fortunately, there are a few gems and tools to make this very easy in Rails applications. In this blog post, we’ll show you 4 different ways to take website screenshots using Rails. So whether you're a beginner or an experienced developer looking to integrate screenshots into your next app, read on for some tips and tricks! ## 4 Ways to Take Screenshots Programmatically with Rails In this article, we'll cover 4 of the most popular ways to take screenshots programmatically. In our examples, we'll create a simple app that lets a user fill out a text box with a URL of their choice and click a button to retrieve and view the screenshot. We'll be using Rails 7 throughout this article. However, these examples should work for older versions of Rails as well. We'll cover the following options: 1. Puppeteer & Grover 2. Cloudinary + URL2png 3. html2canvas 4. Urlbox First up, Puppeteer & Grover... ### Puppeteer & Grover Puppeteer is an API that allows a user to control Chrome or Chromium in either headless or full (non-headless) mode. It’s a versatile package with many features and is commonly used to take screenshots. To best use Puppeteer with Rails, there’s a handy gem built on top of Puppeteer called Grover. Grover makes it easy to call a `.to_pdf` type method to create a screenshot in the format of your choosing. #### Basic set-up and configuration Let’s set up the project by firing up a new Rails app and moving into our new app. In the terminal, we'll add the following command: `rails new puppeteer && cd puppeteer` Next, we’ll need to install Puppeteer and Grover to take screenshots. In your gemfile, add the following line: `gem grover` Then go ahead and run `bundle install`. We'll also want to get Puppeteer installed, so type `yarn add puppeteer` into your terminal to set up your project with Puppeteer. #### Adding a route and creating our view That's it for the configuration work. Our next step is to create a basic view where we'll be able to see our text field and button. First up, we'll add a default route so we can see our form as soon as we fire up our server. In your `routes.rb` file, add `root "screenshot#show"` before the last end tag. Before we load our page, we'll want to make sure that we have something to show our visitors. In the `app/views/` folder, screen a folder called `screenshot` and inside it, add a file called `show.html.erb`. Inside this show view, we'll add a form to capture a URL. ```erb <%= form_with(url: root_path, method: :get) do |form| %> <%= form.text_field :screenshot_url %> <%= form.submit %> <% end %> <% if @image %> <%= image_tag "data:image/png;base64,#{Base64.strict_encode64(@image)}" %> <% end %> ``` This form will submit to the show method in our soon to be created screenshot\_controller file. Then, if Puppeteer comes back with an image, we'll display it in an image tag. #### Setting up the controller Now that we have a show view, we'll need a controller action for it. In `app/controllers/` create a file called `screenshot_controller.rb`. Inside that file, drop the following code: ```ruby class ScreenshotController < ApplicationController def show if params[:screenshot_url] url = ActionController::Base.helpers.sanitize(params[:screenshot_url]) @image = Grover.new(url).to_png end end end ``` This code will take the URL the user entered in the form (if it exists) and convert it into a .png with Grover. `@image` will give us a PNG data file that we'll then take and display in the view. Go ahead and start your `rails server`, enter in the URL of a site you want to screenshot, click the button, and watch as it appears in the view. Pretty cool, huh? If you want to customize your [configuration](https://github.com/Studiosity/grover#configuration) further, you can update an initializer file with the options you prefer. To produce the image above, ours is set to the following: ```ruby # config/initializers/grover.rb Grover.configure do |config| config.options = { user_agent: 'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0', emulate_media: 'screen', bypass_csp: true, media_features: [{ name: 'prefers-color-scheme', value: 'dark' }], vision_deficiency: 'deuteranopia', extra_http_headers: { 'Accept-Language': 'en-US' }, cache: false, timeout: 0, # Timeout in ms. A value of `0` means 'no timeout' launch_args: ['--font-render-hinting=medium'], wait_until: 'domcontentloaded' } end ``` ![screenshot taken with Puppeteer with vision deficiency preview](/content/website-screenshots-rails/theguardian.png) #### Benefits and Drawbacks of Using Puppeteer for Screenshots The advantage of Puppeteer is that it is well maintained and has plenty of options to customize your screenshots with - for example, color blindness simulation, PDF support, setting locations, and disabling javascript. However, because it is so versatile, it’s easy to get lost in the amount of features and options you can choose from. Plus, If you’re going to be taking lots of screenshots, you may need to maintain your own cluster which can increase the number of systems you’ll need to spin up and maintain. *** ### Cloudinary + URL2png Cloudinary is a fantastic service for storing and serving media files. They also integrate with a screenshot service called URL2png to make taking screenshots easy. For this example, we'll need to do a bit more setup than Puppeteer. 1. You'll first need to [sign up for a Cloudinary account](https://cloudinary.com/users/register/free). 2. Once you have your account set up, you'll need to [register for the URL2png add-on](https://cloudinary.com/console/c-43604748b31d9da163fc12b3f86da0/addons#url2png) through their website. One important thing to note is that URL2png does not offer free versions on their homepage, but with a Cloudinary account, you can get up to 50 free screenshots. #### Basic set up and confirmation Before we get into installing the gem, let's first get a fresh Rails app started by typing the following into the terminal: `rails new cloudinary && cd cloudinary` In your gemfile, add the following line: `gem cloudinary` Once it's in your gem file, run `bundle install`. In order to access Cloudinary through its API, you'll also need a way to send Cloudinary your API key and secret. When you're logged in to the Cloudinary application, you can download your cloudinary.yml file at [https://cloudinary.com/console/cloudinary.yml](https://cloudinary.com/console/cloudinary.yml) & add it to your config folder. Beware! This file contains secrets so if you’re following these steps for a production app, please replace your keys with a reference to the credential file where you’ll keep them safe! #### Views, controllers, and route Similar to Puppeteer above, we'll now set up a basic route, view, and controller action. We'll create a root route in `routes.rb` file by adding `root "screenshot#show"` before the last end tag. Then, in the `app/views/` folder, screen a folder called `screenshot` and inside it, add a file called `show.html.erb` and add the following code to it: ```erb <%= form_with(url: root_path, method: :get) do |form| %> <%= form.text_field :screenshot_url %> <%= form.submit %> <% end %> <% if @screenshot_url %> <%= cl_image_tag(@screenshot_url.to_s , :sign_url => true, :type => "url2png") %> <% end %> ``` That's it for the view. To be able to access that view with the route we've created, we'll need to go to `app/controllers/` and create a file called `screenshot_controller.rb`. Inside that file, drop the following code: ```ruby class ScreenshotController < ApplicationController def show if params[:screenshot_url] @screenshot_url = params[:screenshot_url] end end end ``` Start your Rails server with `rails s` and you should be able to enter a url and get a screenshot of it. #### Benefits and Drawbacks of Using Cloudinary & URL2png for Screenshots We'd recommend the Cloudinary + URL2png option if you already use Cloudinary and need a handful of screenshots or want to take advantage of the many image transformations Cloudinary offers. However, you'll need to manage multiple accounts and, if you want to take more than 50 screenshots, will need to sign up for a plan with URL2png and depending on your usage, potentially a plan with Cloudinary as well. *** ### html2canvas While not a gem, html2canvas is easy to integrate into a Rails app with a little sprinkling of javascript with help from StimulusJS. However, html2canvas only lets you take screenshots of your own app. So we'll modify our screenshot button app a little here. Let's get set up. Just like the previous options, we'll create a new app, set up our app, create our view/route/controller and try it out. #### Setup Because html2canvas is a JavaScript library, we're going to use StimulusJS to make integrating all of the JavaScript-related pieces really easy for ourselves. In the terminal, run: `rails new htm2canvas && cd html2canvas` Then, inside your gemfile, add `gem 'stimulus-rails'` then `bundle install`. This will create a few files for you, including `hello_controller.rb` which we'll use in just a few steps. We'll then add html2canvas by installing it via npm with the following command: `npm install html2canvas` Because we're using Rails 7, we can pin html2canvas to our import map by running: `./bin/importmap pin html2canvas` #### Adding a route and creating our view and controller files Similar to the examples above, we'll add a basic route, view, and controller action. First up, create a root route in `routes.rb` file by adding `root "screenshot#show"` before the last end tag. Then, create a new file called `show.html.erb` in `app/views/screenshot`. We'll update show\.html.erb to look like this: ```html
``` The `data-controller` tells StimulusJS we want to use the controller named "hello" that's located at `app/javascript/controllers/hello_controller.js`. Inside that file, we will have a method called `capture` that will use html2canvas to take a screenshot of our site. Remember, html2canvas can not take screenshots of external URLs. Inside `hello_controller.js` we'll add the following: ```javascript import { Controller } from "@hotwired/stimulus"; import html2canvas from "html2canvas"; export default class extends Controller { capture() { html2canvas(document.body).then(function (canvas) { var screenshot = canvas.toDataURL("image/jpg"); window.open(screenshot, "_blank"); }); } } ``` Now, when you run your Rails server, you should see a button that can take a screenshot of your application and display it in a new window. #### Benefits and Drawbacks of Using html2canvas for Screenshots Again, the use case for html2canvas is rather narrow and does not offer many customizations. However, for simple screenshots of your own application, html2canvas may be just what you're looking for. *** ### Urlbox Next up is Urlbox. Setup for Urlbox is easier than others for this example. They're also working on a [gem](https://github.com/urlbox/urlbox-ruby) that'll help speed this process up even faster. Let's spin up a new app and call it urlbox `rails new urlbox && cd urlbox` #### Adding a route and creating our view and controller files Similar to the examples above, we'll add a basic route, view, and controller action. First up, create a root route in `routes.rb` file by adding `root "screenshot#show"` before the last end tag. Then, create a new file called `show.html.erb` in `app/views/screenshot`. We'll update show\.html.erb to look like this: ```erb <%= form_with(url: root_path, method: :get) do |form| %> <%= form.text_field :screenshot_url %> <%= form.submit %> <% end %> <%= image_tag @image if @image %> ``` This will create a button that submits the user entered URL address to Urlbox and then displays it if it exists. In the `app/controlls/screenshot_controller.rb`, we'll add the code below. While we'll put this in the controller for this example, you could extract this into a concern or as a module in you `/lib` folder. ```ruby class ScreenshotController < ApplicationController require 'openssl' require 'open-uri' def show if params[:screenshot_url] url = ActionController::Base.helpers.sanitize(params[:screenshot_url]) @image = urlbox(url, width: 1920, height: 1080, block_ads: true, hide_cookie_banners: true, retina: true) end end private def encodeURIComponent(val) ERB::Util.url_encode(val) end def urlbox(url, options={}, format='png') urlbox_apikey = 'pasteyourAPIkeyhere' urlbox_secret = 'yoursecretkeygoeshere' query = { :url => url, # required - the url you want to screenshot :force => options[:force], # optional - boolean - whether you want to generate a new screenshot rather than receive a previously cached one - this also overwrites the previously cached image :full_page => options[:full_page], # optional - boolean - return a screenshot of the full screen :thumb_width => options[:thumb_width], # optional - number - thumbnail the resulting screenshot using this width in pixels :width => options[:width], # optional - number - set viewport width to use (in pixels) :height => options[:height], # optional - number - set viewport height to use (in pixels) :quality => options[:quality], # optional - number (0-100) - set quality of the screenshot :block_ads => options[:block_ads], # optional - boolean - block ads from loading :hide_cookie_banners => options[:hide_cookie_banners], # optional - boolean - hide cookie banners :retina => options[:retina], # optional - boolean - return a retina screenshot # add more options here as you wish } query_string = query. sort_by {|s| s[0].to_s }. select {|s| s[1] }. map {|s| s.map {|v| encodeURIComponent(v.to_s) }.join('=') }. join('&') token = OpenSSL::HMAC.hexdigest('sha256', urlbox_secret, query_string) "https://api.urlbox.com/v1/#{urlbox_apikey}/#{token}/#{format}?#{query_string}" end end ``` Don't forget to swap your own API key in for the fillers in the `def urlbox` method! Once you have this in your controller, fire up your server by running `rails server` in your terminal. Enter a URL (ex. [https://wsj.com](https://wsj.com)) and a full-size, retina-quality screenshot of the site will appear - without ads and any cookie banners you would usually get. Heads up, because the image quality is so high, it can take a couple of seconds to load! ![screenshot taken of the NYT sans ads with Urlbox](/content/website-screenshots-rails/urlbox-no-ads-nytscreenshot.png) #### Using Webhooks to Render Screenshots Asynchronously with Urlbox Urlbox offers a webhook option to make rendering screenshots asynchronously incredibly easy. Simply pass your webhook URL in as an option and Urlbox will send a POST request back to that url with data about the screenshot in JSON format once it has completed rendering. 🤯 Let's add it to our sample app. First up, in your `routes.rb` file, add the following line: `post 'screenshot/urlbox_webhook', to: 'screenshot#urlbox_webhook'` This will create a route that Urlbox will be able to POST the screenshot data to. We'll do more with this route shortly. In order to test out our webhook, we'll use ngrok. If you haven't installed it yet, there are great instructions on how to do so [here](https://ngrok.com/download). Let's fire ngrok up with the following command: `ngrok http 3000` Once we have ngrok up and running, we can start with making some modifications to our options and call to Urlbox in with the following lines in `screenshot_controller.rb`: In the `def urlbox` method inside the `query` definition where we have our existing options, we'll add the following option: `:webhook_url => options[:webhook_url]` We'll then update our call to Urlbox to include information for our new option: `@image = urlbox(url, width: 1920, height: 1080, block_ads: true, hide_cookie_banners: true, retina: false, dark_mode: true, webhook_url: "https://12a3-45-67-89-000.ngrok.io/screenshot/urlbox_webhook")` Note: you'll want to replace the numbers & letters part of ngrok URL with the ones visible in your ngrok terminal. Next up, we'll create a controller action for our new webhook route. This will allow us to take the data Urlbox gives us and do things with it. In `screenshot_controller.rb` we'll add the following under our show action: ```ruby def urlbox_webhook data = JSON.parse(request.body.read) # Do something cool with our asynchronously rendered screenshot end ``` That's it! Now, when we ask Urlbox for our screenshot, we'll also get a POST request. If you visit your web interface's inspect page (typically at http\://127.0.0.1:4040/inspect/http), you should be able to see the following: ```json { "event": "render.succeeded", "renderId": "19a59ab6-a5aa-4cde-86cb-d2b23302fd84", "result": { "renderUrl": "https://renders.urlbox.com/urlbox1/renders/6215a3df94d7588f7d910513/2022/7/6/19a59ab6-a5aa-4cde-86cb-d2b23302fd84.png", "size": 34097, "renderTime": 6609, "queueTime": 127, "bandwidth": 9429299 }, "meta": { "startTime": "2022-07-06T17:49:18.593Z", "endTime": "2022-07-06T17:49:21.103Z" } } ``` Urlbox's webhook option is a great way to process screenshots in the background so that you and your users can continue to perform tasks while waiting for your Urlbox renderings to come back. #### Benefits and Drawbacks of Using Urlbox for Screenshots You may notice the different options where we define `query` above. Urlbox has a large amount of options to choose from including retina-quality images, ad blocking, selector targeting, and more. You can check out the long list of options [here](https://urlbox.com/docs/options.md). Plus, if you don't want to store your screenshots locally or in ActiveStorage, Urlbox lets you set an S3 bucket [(docs here)](https://urlbox.com/docs/options.md#storage-options) that you've configured in your account so that you can send all your screenshots there *automatically*. Once you have Urlbox set up, you can also connect it to Zapier so non-engineering staff can create workflows around the screenshots you're capturing. *** ### Now go take some screenshots in Rails! As you can see, there are multiple ways to generate screenshots in your Ruby on Rails apps. Some approaches like URL2png are good for simple, straightforward use cases while others, like Urlbox, allow for multiple options like S3 integration, webhooks, target selection, retina-quality captures, and more. If you're looking for an easy way to take website screenshots or PDFs and add them to your Rails project, give Urlbox a try. It’s free to get started, and as you can see in the example above, setup is super easy. Just sign up for an account, generate a token, and start taking screenshots! --- # Generating Website Screenshots With Ruby > I will explore different approaches to generating website screenshots with Ruby using Selenium, Grover, Playwright and Urlbox Source: https://urlbox.com/website-screenshots-ruby Last updated: 2022-06-29 --- Providing a great user experience is probably one of the best ways to build a loyal customer base that's why whenever I have to deal with external websites I like to provide previews of those URLs inside the interface. There are of course numerous other reasons why our applications would require generating screenshots In this blog post, I will explore different approaches to generating website screenshots with Ruby Let's create a folder first ```bash mkdir screenshot-ruby cd screenshot-ruby ``` ## Selenium Webdriver [Selenium](https://github.com/SeleniumHQ/selenium) provides [official ruby bindings](https://github.com/SeleniumHQ/selenium/wiki/Ruby-Bindings) using which we can navigate to websites and generate screenshots. First, we will need to download and set up an appropriate web driver to work with selenium, follow the instructions mentioned [here](https://www.selenium.dev/documentation/webdriver/getting_started/install_drivers/) to install the required driver as per your operating system and browser version. Once done, we will install the gem to get started ```bash gem install selenium-webdriver ``` Now let's write the script to generate a screenshot and save it as `selenium.rb` ```ruby require "selenium-webdriver" driver = Selenium::WebDriver.for :chrome driver.navigate.to "https://google.com" driver.save_screenshot("selenium.png") driver.quit ``` we will run this with ```bash ruby selenium.rb ``` we will now see the script has generated a screenshot as `selenium.png` ![Selenium Webdriver](/content/website-screenshots-ruby/selenium.png) Using Selenium we can control every aspect of the browser and mimic user behaviour. Let's take a screenshot of a specific element ```ruby require "selenium-webdriver" driver = Selenium::WebDriver.for :chrome driver.navigate.to "https://urlbox.com" element = driver.find_element(tag_name: "main") element.save_screenshot("selenium2.png") driver.quit ``` This will capture only the contents of `main` element. Although Selenium provides a low-level API on top of browsers, it comes with a learning curve and a lot of dependencies on browsers and their drivers. Moreover, running this approach on a server could be very expensive. ## Grover [Grover](https://github.com/Studiosity/grover) is a wrapper on top of the [puppeteer](https://github.com/puppeteer/puppeteer) to automate the browser for converting web pages to images Let's install the required dependencies ```bash gem install grover npm init -y npm install puppeteer touch grover.rb ``` open `grover.rb` in your favorite code editor ```ruby require "grover" grover = Grover.new('https://urlbox.com') # Pick your perferred format png = grover.to_png jpeg = grover.to_jpeg File.write("grover.png", png) File.write("grover.jpeg", jpeg) ``` now when we run the following script with \`ruby grover.rb\`\` it should generate a screenshot of the specified URL. ![Grover Screenshot](/content/website-screenshots-ruby/grover.png) When we open the image file we can see it has only captured the hero part of the website. Let's change that to capture the entire website ```ruby //.. grover = Grover.new('https://urlbox.com', { full_page: true }) //.. ``` when we run this script again we should see generated an image with the entire website. Grover can be [configured](https://github.com/Studiosity/grover#configuration) based on our requirements. While this approach works it has its own limitations and challenges. First and foremost, it is a resource-hungry approach, as soon as we start generating more screenshots it will start occupying a larger chunk of our server memory leaving less room for any other process, It may become a bottleneck to scale. Secondly, this approach introduces multiple dependencies i.e Nodejs & Chromium in our application, which would require separate efforts to maintain in future. ## Playwright [Playwright](https://playwright.dev/) is a cross-browser automation engine developed by Microsoft team. There is [playwright ruby gem](https://github.com/YusukeIwaki/playwright-ruby-client) available which can be used to generate website screenshots. Again, we will install dependencies before we start writing code ```ruby gem install playwright-ruby-client npm install playwright ``` Let's get down to writing code ```ruby require 'playwright' Playwright.create(playwright_cli_executable_path: './node_modules/.bin/playwright') do |playwright| playwright.chromium.launch(headless: true) do |browser| page = browser.new_page page.goto('https://playwright.dev') page.screenshot(path: './playwright.png') end end ``` We will save this as `playwright.rb` and run it `ruby playwright.rb`. Now we should see it generate a screenshot of the url ![Playwright Screenshot](/content/website-screenshots-ruby/playwright.png) Playwright can be useful if there is a requirement of generating screenshots from different browsers, however, it does create the same set of challenges as puppeteer regarding dependencies maintenance. ## Urlbox [Urlbox]() is a [website screenshot API](https://urlbox.com/screenshot-api.md) which reduces the efforts required to generate website screenshots drastically. Let's take a look at how We will first grab credentials to use for their API ![Urlbox Credentials](/content/website-screenshots-ruby/urlbox-creds.png) Now let's install their [official website screenshot gem](https://github.com/urlbox/urlbox-ruby) then we will create a file called `urlbox.rb` and use their official gem to generate a screenshot ```ruby require 'urlbox/client' urlbox_client = Urlbox::Client.new(api_key: '', api_secret: '') screenshot_url = urlbox_client.generate_url({url: 'https://urlbox.com/'}) # This can be used for image url <%= image_tag screenshot_url %> response = urlbox_client.get({ url: "https://urlbox.com/", format: "jpeg" }) File.write('urlbox.jpeg', response.body) ``` above script will generate the following image ![Urlbox screenshot](/content/website-screenshots-ruby/urlbox.jpeg) now we have generated screenshots of the website without introducing any javascript dependency using an approach which can be scaled as we grow. Moreover, Urlbox supports a [wide range of options](https://urlbox.com/docs/options.md) such as "retina", "dark\_mode", "block\_ads" etc. which can improve the end result drastically. Let's update our above script to try out some options ```ruby response = urlbox_client.get({ url: "https://urlbox.com/", format: "jpeg", retina: true, full_page: true, wait_until: "domloaded" }) ``` This will generate a full page screenshot of the page ## What have we learned so far? Generating website screenshots is an expensive memory operation and comes with a bunch of dependencies to maintain. Whereas, options like Urlbox are easier to get started and come with so many useful options to give us a high-quality final product. --- # How to Take a Screenshot of a Web Page with Rust > In this article, you'll learn how to take screenshots in Rust using several Rust crates. Source: https://urlbox.com/website-screenshots-rust Last updated: 2022-07-29 --- As a developer, you might have come across a situation where you need to take screenshots of web pages. For example, you might want to take regular screenshots of a website for compliance or monitoring purposes, generate a PDF invoice from an invoice on a web page, or create image assets from dynamic HTML, CSS, and SVG. When taking screenshots of websites, many solutions include some form of JavaScript. You might think you need to write a Node.js app to capture screenshots you can use in Rust. However, this isn't the case! In this article, you'll learn how to take screenshots in Rust using several Rust crates. You'll also see how you can use a screenshot service like Urlbox to make taking screenshots in Rust easier. ## Prerequisites To follow along with the code samples in this article, you must [install Rust and Cargo](https://doc.rust-lang.org/cargo/getting-started/installation.html). The code samples in this article are written to run in Rust 1.62. You will also need to [download Google Chrome](https://support.google.com/chrome/answer/95346) as some code samples use Google Chrome in headless mode. Finally, depending on your development environment, you may need to install a C compiler, which Rust will use to build some dependencies. One such compiler is the [GCC compiler](https://gcc.gnu.org/install/). You can also find all the code in this article in the associated [GitHub repository](https://github.com/ivankahl/rust-website-screenshot-code-samples). ## Getting Started You will first create a new Rust project using Cargo. Open a terminal and type the following Cargo command: ```bash cargo new rust-screenshots ``` The command will create a new Rust project in the `rust-screenshots` folder. Then, you can open the folder in your favorite code editor and follow the code samples below. ## Using the headless\_chrome Crate The [headless\_chrome crate](https://crates.io/crates/headless_chrome) is the Rust equivalent of [Puppeteer](https://pptr.dev/), a JavaScript library that lets you control Chrome or Chromium from a Node.js application. The crate lacks some of the functionality found in Puppeteer, but it does support screenshotting webpages. To install headless\_chrome, open your `Cargo.toml` file and add the following line in the dependencies section: ```toml headless_chrome = "0.9.0" ``` You can now open the `main.rs` and add the following code: ```rs use std::fs; use headless_chrome::{Browser, protocol::page::ScreenshotFormat}; fn main() -> Result<(), Box> { // Open a new instance of Chrome let browser = Browser::default()?; // Chrome always opens with one tab open, so // you just get that initial tab. let tab = browser.wait_for_initial_tab()?; // Navigate to the website and wait for it to // finish loading tab.navigate_to("https://www.howtogeek.com/")?; tab.wait_until_navigated()?; // Screenshot the page to a PNG file and return // the bytes for that PNG let png_data = tab.capture_screenshot( ScreenshotFormat::PNG, None, true)?; // Save the bytes to a screenshot.png file fs::write("screenshot.png", png_data)?; Ok(()) } ``` You'll see that you first create a new Chrome browser instance. You'll not pass in any configuration options, so you can use the default method to start it. You'll notice that you don't have to create a tab—when Chrome opens, it always has one tab open so you can get a reference to the initial tab. Once you have a reference to the tab, you can use it to navigate to the URL you would like to screenshot. You use the`.wait_until_navigated()` method to wait for most of the page to load before continuing with code execution. You then take a screenshot of the webpage once it's finished loading. The `capture_screenshot` method returns the raw PNG bytes, which you can save to a file. You can build and run the code using the following Cargo command: ```rs cargo run ``` When the program has finished executing, you should see a `screenshot.png` file that looks something like this: ![The screenshot generated using headless\_chrome's default options](/content/website-screenshots-rust/3MhyNDB.png) It's not very impressive. The page doesn't look like it finished loading, and the browser's window size is too small. There is also an unappealing sidebar on the right side of the screenshot. The headless\_chrome crate does offer features that might fix some of these issues. You can enter the code sample below into your `main.rs` file: ```rs use std::fs; use std::thread::sleep; use std::time::Duration; use headless_chrome::{LaunchOptionsBuilder, Browser, protocol::page::ScreenshotFormat}; fn main() -> Result<(), Box> { // Configure the launch options for Chrome before // starting the browser. let options = LaunchOptionsBuilder::default() // Make the window bigger .window_size(Some((1920, 1080))) .build()?; // Open a new instance of Chrome with the specified // options let browser = Browser::new(options)?; let tab = browser.wait_for_initial_tab()?; tab.navigate_to("https://www.howtogeek.com/")?; tab.wait_until_navigated()?; // Sleep for some more seconds to make sure everything // has loaded sleep(Duration::from_secs(5)); let png_data = tab.capture_screenshot( ScreenshotFormat::PNG, None, true)?; fs::write("screenshot.png", png_data)?; Ok(()) } ``` You'll notice a few differences in the code sample above. First, instead of using the default configuration to start Chrome, you're now going to create a `LaunchOptions` object using the `LaunchOptionsBuilder`. This object will let you configure browser settings, such as the window size, allowing you to take a better screenshot. Once you've configured the `LaunchOptions` object, you can pass it to the `Browser` constructor. The code also calls the `sleep` method, which gives the page more time to load in the browser before taking a screenshot. The remaining code is like the first code example. You can rerun the code and should see the following screenshot: ![The screenshot generated using headless\_chrome with the LaunchOptions](/content/website-screenshots-rust/jaiUET1.png) The screenshot looks better than the first attempt. The viewport is bigger, so more of the actual website is visible in the screenshot. The page was also able to load before taking the screenshot. The disadvantage is that ads appear on the web page's top and right. The unappealing scrollbar is also still there, though it's less prominent. ## Using the webscreenshot Crate The [webscreenshot crate](https://lib.rs/crates/webscreenshot) is another library that lets you take website screenshots. The library aims to minimize the code needed to take a website screenshot. It has a method to screenshot a given URL and another to save that screenshot to a file. The library uses the headless\_chrome crate you saw in the previous code sample. To add the crate, remove all your existing dependencies in your `Cargo.toml` file and add the following code: ```rs webscreenshot = "0.2.2" ``` You can then replace the code in your `main.rs` file with the following: ```rs use webscreenshotlib::{screenshot_tab, write_screenshot, OutputFormat}; fn main() -> Result<(), Box> { // Take a screenshot and save the image to a variable let image_data = screenshot_tab( // The URL you would like to screenshot "https://www.howtogeek.com/", // The output format for the screenshot OutputFormat::PNG, // Quality - ignored for PNG 100, // Whether to screenshot visible only or not true, // The width of the browser 1920, // The height of the browser 1080, // The element that should be screenshotted. // We leave it blank to screenshot everything. "")?; // Write the screenshot you took earlier to a file write_screenshot("screenshot.png", image_data)?; Ok(()) } ``` Run the code using the following Cargo command: ```rs cargo run ``` You should see a screenshot like the one below: ![The screenshot file generated using the webscreenshot crate](/content/website-screenshots-rust/xcG8i21.png) The screenshot looks very similar to the screenshot taken with headless\_chrome, but one difference is that there are no advertisements in this screenshot. The missing advertisements aren't due to ad blocking, but rather because [the library does not appear to wait long enough for the advertisements to load](https://docs.rs/webscreenshot/latest/src/webscreenshotlib/lib.rs.html#31-70). If ads had loaded with the page, they would have been included in the screenshot. You can also see that the unappealing scrollbars on the right are still present in the screenshot. ## Using the wkhtmltopdf Utility and Crate [wkhtmltopdf](https://wkhtmltopdf.org/index.html) is an open source, command-line utility that converts HTML to PDF and several image formats. Libraries exist for several programming languages that let you use wkhtmltopdf from those languages. Rust is one such language. You can use the [wkhtmltopdf crate](https://crates.io/crates/wkhtmltopdf) to call the wkhtmltopdf utility from Rust. Before using this crate, you must install wkhtmltopdf on your computer. The utility is cross-platform, and you can find installation instructions for your particular platform on their [download page](https://wkhtmltopdf.org/downloads.html). Once you've installed the utility and confirmed that it works, you can add the [wkhtmltopdf crate](https://crates.io/crates/wkhtmltopdf) to your `Cargo.toml` file: ```toml wkhtmltopdf = "0.4.0" ``` You can now replace the code in your `main.rs` file with the code sample below: ```rs use wkhtmltopdf::{ImageApplication, ImageFormat}; fn main() -> Result<(), Box> { // Create a new image application that you will use let image_app = ImageApplication::new()?; // Use the image application above to take a PNG screenshot // of the specified URL let mut image_out = image_app.builder() .format(ImageFormat::Png) .screen_width(1920) .build_from_url(&"https://www.howtogeek.com/".parse().unwrap())?; // Save the new screenshot to a file image_out.save("screenshot.png")?; Ok(()) } ``` The code sample above is brief and offers little in the way of customization options. First, it creates an instance of `ImageApplication`, letting you interact with the wkhtmltopdf utility. Then the `builder()` method is used on the `ImageApplication` to build a screenshot of the specified URL. Before taking the screenshot, you can configure some options, such as the screen width and format of the screenshot. When configuring the screenshot, you call the `.build_from_url()` method to screenshot a specific URL. After you've captured the screenshot, you save the output to a file. You can rerun the code using Cargo: ```bash cargo run ``` You should see a `screenshot.png` file in your project folder. If you open it, you should see a screenshot that looks something like the screenshot below: ![The screenshot generated using wkhtmltopdf](/content/website-screenshots-rust/zSz17AN.png) It's important to note that this image had to be significantly compressed in order to be uploaded—the original file size was twenty-six MB. You can change this behavior, but it will require some [additional configuration to get it right](https://stackoverflow.com/questions/33528780/any-way-to-reduce-file-size-using-wkhtmltopdf). You will also notice that wkhtmltopdf took a full-page screenshot, which may not suit your needs. Unfortunately, the wkhtmltopdf crate does not appear to offer an easy way to change this functionality without diving into the [low-level module](https://anowell.github.io/wkhtmltopdf-rs/wkhtmltopdf/lowlevel/index.html). In addition, while most of the page renders accurately in the screenshot, you might notice that some parts of the page, especially towards the bottom, didn't finish loading before wkhtmltopdf took the screenshot. In addition to being compressed, this screenshot has been cropped to make viewing it more convenient: it was originally twice as long, and the lower half of the image was nothing but white space. Finally, there are also no ads in the screenshot, but this is due to the page being captured before it was fully loaded, as wkhtmltopdf does not have any ad blocking features. ## Using the Urlbox Screenshot API [Urlbox](https://urlbox.com/.md) is a [screenshot API](https://urlbox.com/screenshot-api.md) for generating screenshots from URLs. You can capture screenshots of websites in a variety of formats, such as [PNG](https://urlbox.com/url-to-png.md), JPG, WebP, [PDF](https://urlbox.com/url-to-pdf.md), and even SVG. Urlbox also has support for [Google Fonts](https://urlbox.com/webfonts.md) and [emojis](https://urlbox.com/emoji.md), which ensures that your automated screenshots are accurate representations of how the web page should look. You use your own [proxy](https://urlbox.com/docs/options.md#proxy) to avoid having your automation blocked by websites. Urlbox also gives you full control over the quality and dimensions of your screenshots, including partial-page screenshots, and lets you create retina-quality screenshots. You can block ads and hide cookie banners so that nonessential elements don't clutter your screenshot—you can even specify a specific part of the site to capture. And the screenshots taken with Urlbox won't have any unappealing scrollbars! Urlbox has [reasonable pricing options](https://urlbox.com/pricing.md) that start at $19/month and offer a seven-day free trial that you can use to test their service. They also offer an intuitive dashboard that you can use to test different screenshot options. All the dashboard options are available through a REST API, which you can effortlessly consume in Rust. Before using Urlbox, you must [sign up](https://urlbox.com/pricing.md) and retrieve an API key to use in Rust. You will see an API Key and API secret on the dashboard page as soon as you log in. The code sample below will only be using the API key, but it is [recommended](https://urlbox.com/docs/authenticated-requests.md) that you also use the API secret once you become familiar with the Urlbox API and its features. ![You'll see your API Key as soon as the dashboard page loads](/content/website-screenshots-rust/lFJoFVx.png) Once you have your API Key, you can add it to your Rust project as an environment variable. You can do this by creating a file called `.cargo/config.toml` in your project directory and pasting the following content into the file: ```toml [env] URLBOX_API_KEY = ``` Since you will be using the REST API provided by Urlbox, you will need to add an HTTP client library to your Rust project. The code sample below uses the popular [reqwest HTTP client crate](https://crates.io/crates/reqwest) as well as the [tokio crate](https://crates.io/crates/tokio) to help with asynchronous operations. You will also need to add the [futures-util crate](https://crates.io/crates/futures-util) so that you can save the screenshot to a file. Replace the dependencies in your `Cargo.toml` file with the following: ```rs reqwest = { version = "0.11.11", features = ["stream"] } tokio = { version = "1.19.2", features = ["full"] } futures-util = "0.3.21" ``` You can now replace the code in your `main.rs` file with the following: ```rs use futures_util::StreamExt; use tokio::{fs::File, io::AsyncWriteExt}; use reqwest::Client; #[tokio::main()] async fn main() -> Result<(), Box> { // Create a new reqwest client which you will use for our REST // calls to the Urlbox API let client = Client::new(); // Retrieve your API Key from the environment variables let api_key = env!("URLBOX_API_KEY"); // Format your REST API URL with the API Key let api_url = format!("https://api.urlbox.com/v1/{api_key}/png"); // Use the reqwest client to call the REST API URL above // and return the response as a byte stream which you can // save to a file. let mut stream = client.get(api_url) .query(&[ // The URL you want to screenshot ("url", "https://www.howtogeek.com/"), // Specify the screen width to use ("width", "1920"), // Screenshot the entire page ("full_page", "true"), // Click accept on any popups ("click_accept", "true"), // Block any ads that might appear on the page ("block_ads", "true"), // Hide any cookie banners that might appear ("hide_cookie_banners", "true"), // Screenshot the webpage in retina quality ("retina", "true"), // Hide a notification dialog that appears ("hide_selector", "#notificationAllowPrompt") ]) .send() .await? .bytes_stream(); // Create a new file that you can write the response bytes to let mut file = File::create("screenshot.png").await?; // Write the bytes for the screenshot image to a file while let Some(item) = stream.next().await { file.write_all_buf(&mut item?).await?; } Ok(()) } ``` In the code above, you first create a new instance of the request `Client` object. Next, you'll use this client to call the Urlbox REST API. Once you have your client, you can construct your REST API call. First, you retrieve the Urlbox API Key stored in your environment variables using the `env!()` macro, then create a REST API call to the URL using the API Key and `format!()` macro. The actual HTTP request is then made using `.get()`. You can see how you can \[pass query parameters to configure Urlbox's [features](https://urlbox.com/docs/options.md). In this example, you're [blocking ads](https://urlbox.com/docs/options.md#block_ads), [taking a retina quality screenshot](https://urlbox.com/docs/options.md#retina), and [hiding some elements on the page](https://urlbox.com/docs/options.md#hide_selector) before taking a screenshot. Once you've received a response, you must convert it to a byte stream which you can then write to the `screenshot.png` file. You can run the code sample using Cargo: ```rs cargo run ``` You should see a `screenshot.png` file created. When you open it, it should look like this: ![The screenshot generated using Urlbox](/content/website-screenshots-rust/8MhczWq.jpeg) The screenshot is retina quality, yet the file size is significantly smaller than when generating a full-page screenshot using wkhtmltopdf. Also, unlike wkhtmltopdf, Urlbox renders the page perfectly from header to footer. In addition, Urlbox's support for modern CSS has ensured that the page layout in the screenshot is the same as if you were to navigate the website yourself. Finally, you'll also notice that there are no advertisements on the web page, but they haven't left gaps of space, either. You have a beautiful, automated screenshot of a web page that you can now use. ## Conclusion There are many reasons why you might need to take screenshots of web pages programmatically. In this article, you've seen different website screenshot solutions you can use in Rust. If you want to take screenshots of websites manually, you can make use of the [headless\_chrome crate](https://crates.io/crates/headless_chrome), [webscreenshot crate](https://lib.rs/crates/webscreenshot), or [wkhtmltopdf utility and crate](https://wkhtmltopdf.org/index.html). While these solutions generate adequate screenshots, there are many edge cases such as advertisements and cookie banners that you must consider. You'll be able to set up your screenshot service relatively quickly, but spend significantly more time trying to perfect and maintain it. If you want to quickly generate screenshots or PDFs of websites with minimal maintenance or overhead, [Urlbox](https://urlbox.com/.md) is an excellent solution. Its REST API makes it easy to integrate Urlbox into your Rust application. It's also easy to block ads, hide certain elements, and take retina-quality screenshots. You also have the choice to take a screenshot of the viewport, full page, or even a specific element on a web page when using Urlbox. With Urlbox you can: - [Convert HTML to Image](https://urlbox.com/html-to-image.md) - [Generate PDFs from HTML](https://urlbox.com/html-to-pdf.md) - [Turn URLs into images](https://urlbox.com/url-to-image.md) - [Handle Webfonts, emoji and more](https://urlbox.com/features.md) Discover the power of the Urlbox in our [API docs](https://urlbox.com/docs.md).

Here are 5 of the best website screenshot APIs and what makes them stand out from the crowd. Source: https://urlbox.com/screenshot-api/for-business Last updated: 2025-03-21 --- Website screenshots can be a great way to track website changes or understand how your website performs for your users. But there’s a problem: many websites are too complex to be fully captured in a screenshot. Many businesses who turn to screenshot APIs struggle with: 1. Building their website screenshot solution in-house 2. Taking website screenshots at scale 3. Scaling, monitoring, and maintaining their in-house screenshot service. For example, some website screenshots capture only the visible part of a web page. This may suffice for some use cases, but it’s not always enough. And some website screenshot APIs take up to 20 seconds to render a single screenshot. This makes it impractical to use them at scale. There are several website [screenshot APIs](https://urlbox.com/screenshot-api.md) that solve those problems. They help you generate full-page website screenshots at scale, change viewport dimensions to simulate different screen sizes, and provide fast and accurate website rendering. They save you money and time by making website screenshots more accurate. And they do it all in a user-friendly way. Because website screenshots have become very useful for some businesses, several tools have been developed to enable you to generate PDFs, JPGs, or PNGs from a URL or HTML file. Moreover, these tools have allowed developers to use their API to use their features without building their screenshot software from scratch. In this article, we will review 5 of the best website screenshot APIs that you can use to streamline your processes: 1. Urlbox 2. URL2PNG 3. Screenshotlayer 4. ApiFlash 5. ScreenshotAPI We’ll cover the best website screenshot APIs available today, how they work, and why they’re helpful. We also explain why it’s crucial to have a high-quality website screenshot API to ensure your users always get the right information. Let’s dive right into it! Note: Urlbox is our product. We’re proud to be a premium provider of website screenshots,and we take pride in our excellent customer support. Transform the way you generate website screenshots and try Urlbox [here](https://urlbox.com/pricing.md). ## What is a screenshot API? A [screenshot API](https://urlbox.com/screenshot-api.md) is a web service that allows developers to capture pixel-perfect screenshots of websites. Out of the box, screenshot APIs can be used to: - Embed website screenshots into blog posts, documentation, or marketing materials - Capture screenshots at scale for testing or analysis purposes - Create alerts when a webpage changes - Generate Excel files with screenshots on a scheduled basis. To use a screenshot API, you will first need to sign up for an account with your chosen API provider. Depending on your needs, you may need to upgrade your plan to enable all of the features you need. An API key is usually provided when signing up for an account and allows the API to identify who is making the request. The API key allows the service provider to track usage and allocate resources accordingly. It works like this: an API receives a URL as an input and then returns a generated screenshot of that website. The returned image can be saved in PNG or JPEG format. Many providers offer screenshot APIs. Some of them return full-page screenshots, while others – only visible parts of websites. Some support high-resolution screens; others don't. The difference between mobile and desktop versions of websites is also a no-brainer, as some screenshot APIs allow you to specify the screen size and browser user agent. ## What are the advantages of using a website screenshot API? Website screenshot APIs are a great way to add value to your product without building and maintaining the infrastructure yourself. Here are some advantages of using an API: 1. Not writing your microservice This can take months or even years. If you're building a startup, it's more important to focus on making your product awesome and not get distracted by infrastructure. A screenshot API can give you the functionality you need while saving you time and money. 2. Ensure that fonts and emojis are rendered accurately The web has come a long way, but the technology behind browsers is still relatively new. Websites often use non-standard fonts or have custom emojis, which must be rendered correctly for the image to make sense. A screenshot API lets you ensure that these things are displayed accurately in the browser before taking the screenshot. 3. Prevent ads from taking all the attention in your screenshots Website screenshots can often contain ads or distracting elements you don't want to be included in your image. Using a website screenshot API can help you block ads when you convert the HTML files into PNGs. ## Top 5 website screenshot APIs ## 1. [Urlbox](https://urlbox.com/.md) The [Urlbox API](https://urlbox.com/docs.md) provides an easy way to capture screenshots of websites automatically. The tool provides a REST API that generates screenshots using various programming languages from any website. You send us the URL, and we send you the image in your preferred format. We give you full control over the size of images, allowing you to select from a wide range of mobile and desktop screenshots. The API also allows for customization by allowing you to inject javascript, CSS, or HTML into the DOM before taking a screen capture. All requests are made using simple HTTP GET requests with your actions defined by query string parameters. The Urlbox API is blazing fast and can handle hundreds of thousands of requests per day without breaking a sweat. ### Main features 1. #### Retina images Urlbox supports high-quality, high-DPI images for you to generate beautiful, crisp, and pixel-perfect images that look great on [retina](https://urlbox.com/docs/options.md#retina) screens. All you need to do is pass in an additional URL parameter when generating your screenshots to enable this feature. ![](/content/5-website-screenshot-apis-for-your-business/image4.png) 2. #### Block ads or pop-ups We've added a new option to our API and dashboard for taking website screenshots, which allows you to block pop-up windows when generating screenshots. Our screenshot API has always supported advanced features like custom user agent strings and cookies; however, some websites rely on pop-up windows to display content (usually ads), which can get in the way of capturing good screenshots. As a result, we've had several requests for a feature that could help generate clean screenshots by blocking pop-ups. If you'd like to try out this new feature, just tick the ["block ads"](https://urlbox.com/docs/options.md#block_ads) checkbox in your Urlbox dashboard or set "block\_ads=true” in your API request payload when making an API call. ![](/content/5-website-screenshot-apis-for-your-business/image1.png) 3. #### Dismiss cookie banners Cookie banners are a new class of banners that have become increasingly common. Because they're not traditional ads, they don't get dismissed by our ad blocker, which means, in many cases, they'll spoil your screenshots. We've added a new feature to Urlbox called [“hide\_cookie\_banners”](https://urlbox.com/docs/options.md#hide_cookie_banners) which automatically dismisses cookie banners whenever your screenshot is taken. To use it: 1. Scroll down to the 'Blocking' section and check the box labeled "Hide Cookie Banners" 2. Take your screenshot as usual 3. View your screenshot, and you should see that the cookie banner has been removed! ![](/content/5-website-screenshot-apis-for-your-business/image2.png) 4. #### Bring your own proxy We want to make Urlbox as flexible as possible, so we've added the ability to use your [proxy](https://urlbox.com/docs/options.md#proxy) server when taking screenshots. This means that you can use any of our supported screenshot types behind your own proxy server, which will prevent websites from blocking our IP address. We have also introduced proxy support to all Urlbox plans. You can choose a different proxy for each screenshot you generate. ![](/content/5-website-screenshot-apis-for-your-business/image6.png) 5. #### Enable geolocation Urlbox supports enabling geolocation which allows you to emulate the Geolocation API built into modern web browsers. This is useful for testing your website and ensuring that your site looks as expected for users in different parts of the world. To emulate the Geolocation API, you can use Urlbox to specify the latitude, longitude, or accuracy. To do this, simply add one of the “latitude=”, “longitude=”, or “accuracy=” parameters, respectively. ![](/content/5-website-screenshot-apis-for-your-business/image3.png) ### Additional features - Bypass captchas - automatically attempt to solve and bypass any captchas shown. - Choose your render mode - preview all available API options and check API usage on our modern dashboard. - A variety of output formats - screenshot rendering as PNG, JPEG, WEBP, AVIF, SVG, PDF, and even HTML - Delay settings - ensure a screenshot is only taken when a specific element is either in the DOM or has left the DOM. ### Urlbox website screenshots use cases Our simple API is designed to be easy to use and integrate with any existing application. Most of our users can integrate with the Urlbox API within a few minutes. Several customers use Urlbox to generate screenshots and PDFs from their websites. Some of the [use cases](https://urlbox.com/docs.md) include: 1. Designers/developers who want to make sure that the site is rendering correctly before releasing it to production 2. Customer support teams who want to generate invoices for their clients 3. Marketing agencies who need to create assets for ad networks 4. Sales teams that wish to send beautiful-looking emails to their leads by attaching a screenshot or PDF of their website. ### How to capture screenshots of any website with Urlbox The quickest way to get started with Urlbox is to use the [synchronous GET API](https://urlbox.com/docs/getting-started.md). Synchronous GET calls are designed for one-off requests where you need an image immediately. With these calls, we picture the request as a box that you're willing to wait for before you continue (your script won't do anything else until it's processed). If you are making a large number of synchronous requests, you should consider using the asynchronous API to avoid timeouts. ### Pricing Urlbox comes at a fraction of the cost of building and maintaining your own website screenshots microservice. Urlbox has three plans which which each grow as you scale. The prices start at $19 per month. For instance, if you send us 20,000 requests per month on the Lo-Fi plan, we’ll charge you $90. If you send us up to 1,000,000 requests per month, Urlbox charges $3,200. You can also get started with our free 7-day trial. ### Why customers love Urlbox If you are looking for a simple way to capture a screenshot of your website, Urlbox is the perfect solution for your screenshot needs.

[URL2PNG](https://www.url2png.com/) URL2PNG is a service that lets you take high-resolution screenshots of web pages. It is a hosted solution, so there is nothing to install on your server. You just make a GET/POST request to their API, and you get back a screenshot as an image or PDF file. URL2PNG can be used in many ways: - A simple way of publishing live web page screenshots in your blog posts or website - Automatically creating mockups of a website or application - Include thumbnail previews of web pages in search results for your site (similar to the way Google does it). ### Main features With URL2PNG, you can: - generate thumbnails by constraining screenshots based on width. This means that if you have a website that is 1000px wide and you need a thumbnail that is 200px wide, URL2PNG will automatically resize the screenshot to fit your needs - inject your CSS into any page. Just pass the CSS parameter with your custom styles, and they'll take care of the rest - use delayed screenshots. This is great for pages using flash or javascript animations. You can delay the screenshot for up to 10 seconds past document ready and up to 30 seconds total.​ ### Pricing URL2PNG offers three pricing plans. Paid plans are billed monthly and include a 10-day money-back guarantee. They all start at $29 per month and support 5,000 generated screenshots. The plans can go up to $1000 per month for 50,000 generated screenshots, and you can also upgrade to an Enterprise plan for custom pricing. ## 3. [Screenshotlayer](https://screenshotlayer.com/) The Screenshotlayer API is a lightning-fast, highly scalable, and extensible REST API for generating website screenshots. It allows for instant delivery of high-resolution images through a simple API interface that is easy to integrate within any application, framework, or programming language. Their API provides the ability to build custom applications and generate website screenshots on-demand. Whether you're looking to integrate screenshot generation into a current workflow or create a new website screenshot service, Screenshotlayer gives you the flexibility to implement your idea with minimal effort and maximum results. ### Main features With Screenshotlayer, you can: - create snapshots of websites or provide an API endpoint to your users and clients to generate screenshots with custom sizes - have the API directly upload your screenshots to your AWS S3 Bucket.

They can generate images extremely quickly and are scalable to millions of captures per day. ### Main Features ApiFlash offers: - support for user scripts to apply custom CSS changes to the page this allows you to override the default styles of any website with your own - support for arbitrary screen resolutions, allowing you to retrieve a screenshot in any size (e.g., 400x300 or 1024x768) - the possibility to automatically detect fully loaded pages before screenshot capture. ### Pricing Users can expect a free plan for their first 100 screenshots and upgrade to a pay-per-month pricing model, starting at $7 per month for 1,000 screenshots. ApiFlash also offers a Large plan, which includes up to 100,000 screenshots (with JS injection and CSS injection) for up to $180 per month. ## 5. [ScreenshotAPI](https://www.screenshotapi.net/) ScreenshotAPI is a platform that allows you to take full-length screenshots of any website. It works by fetching your requested URL and returning it as an image. ScreenshotAPI can take screenshots of websites that use parallax, lazy loading, infinite scroll, and even those pesky sites that love to hide when you scroll down. ### Main features With ScreenshotAPI, you can: - automatically scale up screenshots taken from a website. This means that you no longer have to worry about exporting separate images for different device resolutions - effortlessly handle those tricky features that are so difficult to capture, such as HTML5 videos, Single Page Apps, Web Fonts, and more - delay loading of your screenshots. ### Pricing With ScreenshotAPI, you can generate 100 free screenshots per month; no credit card required. Once you're ready to scale, the ScreenshotAPI plans start at $9 per month and can go up to $175 per month. ## Other website screenshot APIs to consider The world of website screenshot APIs is huge. There are a lot of website screenshot APIs on the market, and it can be challenging to find the right one. The list above was not exhaustive, so here are some other website screenshot APIs you might want to consider: - Browshot - Scraping Bee - HTML/CSS to Image - Bannerbear. ## How to choose the right website screenshot API The following criteria should be taken into account when choosing the right screenshot API: 1. Format: A good API will provide a variety of output formats so that you can use the one that suits your needs best. For instance, some users will prefer JPEG because it is more flexible, and others will prefer PNG as it offers a better quality/size ratio. 2. Screenshot size: It is also vital to select an API that gives you the ability to crop and resize the screenshots according to your needs. For example, if you want to create a thumbnail image of a website, then use an API with this feature 3. Price: Some APIs require payment while others are free there are pros and cons for both options but make sure that whatever option you choose meets all of your needs before anything else! 4. Reliability: Make sure that your chosen API provider has robust customer support and is ready to help when needed (whenever the website is down, or in case the screenshots don't return on time) 5. Quality: Does the screenshot look pixel-perfect? Is the image cropped correctly? 6. Speed: How long does it take to generate a screenshot? What if you need to generate thousands of them at once? ## See if Urlbox is the right website screenshot service for you Great software takes care of all these points.

Use puppeteer, playwright, electron, nightmare, selenium, phantomjs and urlbox to take website screenshots with javascript Source: https://urlbox.com/7-ways-website-screenshots-nodejs-javascript Last updated: 2025-03-21 --- Using node.js and need to a way to capture website screenshots for your product? This article explores some of the most popular tools and libraries that enable you to easily take website screenshots with javascript and node.js. ## Website screenshots with Puppeteer [Puppeteer](https://github.com/puppeteer/puppeteer) is a node.js library that automates headless chromium and chrome. This allows us to browse to a url and take a website screenshot. It is maintained by the chrome devtools protocol team. -> Check out our article on [using puppeteer to take website screenshots](https://urlbox.com/website-screenshots-puppeteer.md), for a more in-depth look. To get started using puppeteer, first we need to install it using npm: ```zsh npm install puppeteer ``` Next, we need to import the puppeteer module and write our first puppeteer script: ```js screenshot.js const puppeteer = require("puppeteer"); puppeteer .launch({ defaultViewport: { width: 1280, height: 2000, }, }) .then(async (browser) => { const page = await browser.newPage(); await page.goto("https://nytimes.com"); await page.screenshot({ path: "nyt-puppeteer.png" }); await browser.close(); }); ``` Copy the code into a file called `puppeteer-screenshot.js` and run the script. ```zsh node puppeteer-screenshot.js ``` The screenshot generated is named `nyt-puppeteer.png` and looks like this: ![puppeteer screenshot of nytimes](/content/screenshots-javascript/nyt-puppeteer.png) As you can see, most of the screenshot is taken up by an ad on the top, and a cookie banner on the bottom. This is a common issue with taking website screenshots, and can be time consuming to fix. If you're looking for a solution that automatically [blocks ads from screenshots](https://urlbox.com/docs/options/.md#block_ads) and [hides cookie banners](https://urlbox.com/docs/options/.md#hide_cookie_banners) for you, we have built [urlbox](https://urlbox.com/.md) to solve these problems and more. ## Use Playwright to capture website screenshots [Playwright](https://github.com/microsoft/playwright) is the new kid on the block of headless browser automation libraries. Playwright is maintained by microsoft. The API is very similar to puppeteer, in fact some of the original developers of puppeteer are now working on developing and maintaining playwright. The great thing about playwright is that it can be used to automate chromium, firefox and webkit using the same API. This means it could easily be used for cross-browser screenshot testing. First let's install playwright using npm: ```zsh npm install playwright ``` Now we can create our first playwright browser automation script: ```js const { chromium } = require("playwright"); (async () => { let browser = await chromium.launch(); let page = await browser.newPage(); await page.setViewportSize({ width: 1280, height: 1080 }); await page.goto("http://nytimes.com"); await page.screenshot({ path: `nyt-playwright-chromium.png` }); await browser.close(); })(); ``` The script launches the chromium browser, sets the viewport to `1280x1080`, navigates to [http://nytimes.com](http://nytimes.com), and captures a screenshot. Save the following code to `playwright-screenshot.js` and run the script: ```zsh node playwright-screenshot.js ``` Here is the resulting screenshot: ![screenshot of nytimes generated by playwright in chromium](/content/screenshots-javascript/nyt-playwright-chromium.png) Once again, the default out-of-the-box screenshot is obscured by ads and cookie banners. ## Selenium web driver website screenshots [Selenium](https://www.selenium.dev/) is a web automation toolkit that enables cross-browser automation. For each browser we want to automate, we need to install a driver that implements the [W3C's webdriver specification](https://www.w3.org/TR/webdriver/). In order to drive chrome from selenium we will use the `chromedriver` project. Conveniently there is an npm package which installs the chromedriver binary and makes it available to our selenium script. We also need to install the `selenium-webdriver` npm package that works with the browser-specific driver in order to automate them using a high-level API. ```zsh npm install selenium-webdriver chromedriver ``` Now create the selenium screenshot capture script. Save the following code to `selenium-screenshot.js`: ```js const { Builder } = require("selenium-webdriver"); require("chromedriver"); let fs = require("fs"); async function takeScreenshot(url) { //Wait for browser to build and launch properly let driver = await new Builder().forBrowser("chrome").build(); //Navigate to the url passed in await driver.get(url); //Capture the screenshot let image = await driver.takeScreenshot(); await fs.writeFileSync("./nyt-selenium.png", image, "base64"); await driver.quit(); } takeScreenshot("https://nytimes.com"); ``` and run the script: ```zsh node selenium-screenshot.js ``` The script boots up an instance of chrome, then navigates to the URL, takes a screenshot and saves it to the local filesystem as `nyt-selenium.png`. Here is the resulting screenshot: ![nytimes-selenium](/content/screenshots-javascript/nyt-selenium.png) ## Using Electron for website screenshots [Electron](https://www.electronjs.org/) is well known as a platform for building cross-platform desktop apps using the holy trinity of HTML, CSS and JavaScript web technologies. It is the foundation of several desktop apps such as VS-Code, Spotify and Microsoft Teams. Since it uses an instance of chromium to render the app, it can also be used to automate a headless browser and even generate website screenshots. In order to use electron, we need to install it using npm: ```zsh npm install electron ``` Now, let's first create our `main.js` electron entrypoint: ```js const { app, BrowserWindow, ipcMain } = require("electron"); const path = require("path"); const fs = require("fs"); const screenshot = require("./screenshot"); let window; function createWindow() { window = new BrowserWindow({ width: 1280, height: 1024, webPreferences: { nodeIntegration: true, contextIsolation: false, }, }); window.loadFile("./index.html"); window.webContents.openDevTools(); } app.whenReady().then(createWindow); app.on("window-all-closed", () => { if (process.platform !== "darwin") { app.quit(); } }); ipcMain.on("start::screenshot", (event, arg, filename) => { console.log("Starting"); screenshot(arg, filename, (reply) => { console.log("Done", reply); }); }); ``` The `main.js` entrypoint manages the lifecycle of an electron app. It requires `screenshot.js`, which contains the necessary code to navigate to the URL, capture the page content and convert it into PNG format: ```js const { BrowserWindow } = require("electron"); const fs = require("fs"); const path = require("path"); // Offscreen BrowserWindow let offscreenWindow; let nativeImage; // Exported readItem function module.exports = (url, filename, callback) => { // Create offscreen window offscreenWindow = new BrowserWindow({ width: 1280, height: 1080, show: false, webPreferences: { offscreen: true, }, }); // Load item url offscreenWindow.loadURL(url); // Wait for content to finish loading offscreenWindow.webContents.on("did-stop-loading", async () => { // Get screenshot (thumbnail) nativeImage = await offscreenWindow.webContents .capturePage() .then((image) => { fs.writeFileSync(filename, image.toPNG(), (err) => { if (err) throw err; }); return image.toDataURL(); }); let obj = { title: title, url: url, filename }; callback(obj); offscreenWindow.close(); offscreenWindow = null; }); }; ``` Screenshot.js exports a function that takes a url, filename and a callback function. This function is called from main.js and navigates to the passed in URL, then calls `capturePage()` on the BrowserWindow's `webContents` object. The `capturePage` function returns a promise that resolves to a `nativeImage` object, which is the raw image data of the web page's screenshot. The screenshot is then saved to a PNG file. The image data can also be passed back to the main process as a base64 data URL string. Here's the resulting screenshot: ![screenshot of nytimes generated by electron](/content/screenshots-javascript/nyt-electron.png) It is quite inconvenient to use electron for purely generating screenshots as it's main purpose is for writing cross-platform desktop applications. It can sometimes be confusing which code belongs in which context. However, the next library on our list attempts to abstract electron and make it more of a web-automation tool. Urlbox was previously using electron to generate website screenshots, before puppeteer was released. Another downside about electron is that the version of chromium it is reliant on is not updated as frequently as for puppeteer and playwright. This means newer features are slower to support, and security vulnerabilities are more likely to remain unpatched. ## URL to image with Nightmare.js [Nightmare.js](https://github.com/segmentio/nightmare) is a node.js library developed by the team at segment. It is built on top of Electron, but has a higher level API which makes it easier to work with for simple tasks, such as capturing screenshots of websites. Install nightmare via npm: ```zsh npm install nightmare ``` Now create the file `nightmare-screenshot.js` that uses nightmare to render a website screenshot: ```js const Nightmare = require("nightmare"); const nightmare = Nightmare({ show: true, gotoTimeout: 10000 }); nightmare .goto("https://nytimes.com") .screenshot("nyt-nightmare.png") .end() .then(console.log) .catch((error) => { console.error("screenshot failed:", error); }); ``` Run the script: ```zsh node nightmare-screenshot.js ``` You should see the browser open and load the nytimes.com page. Unfortunately, when I tried running this script, the nytimes.com site initially loaded, but then disappeared, and I was left with a blank screenshot. When checking the devtools console, I could see a couple of JavaScript errors: ![image of devtools errors when running nightmare](/content/screenshots-javascript/nightmare-errors.png) I assume that nightmare is using an old version of electron which in turn is using an out of date version of chromium that fails to load the nytimes.com site fully. Let's try again with a different url: ```js const Nightmare = require("nightmare"); const nightmare = Nightmare({ show: true, gotoTimeout: 10000 }); nightmare .goto("https://bbc.com") .screenshot("bbc-nightmare.png") .end() .then(console.log) .catch((error) => { console.error("screenshot failed:", error); }); ``` Running this script I was also having trouble, this time nightmare was emitting `navigation error`: ```zsh screenshot failed: Error: navigation error at unserializeError (/node_modules/nightmare/lib/ipc.js:162:13) at EventEmitter. (/node_modules/nightmare/lib/ipc.js:89:13) at Object.onceWrapper (node:events:510:26) at EventEmitter.emit (node:events:390:28) at ChildProcess. (/node_modules/nightmare/lib/ipc.js:49:10) at ChildProcess.emit (node:events:390:28) at emit (node:internal/child_process:917:12) at processTicksAndRejections (node:internal/process/task_queues:84:21) { code: -3, url: 'https://www.bbc.com/' } ``` Looking at the [github repo](https://github.com/segmentio/nightmare) for nightmare, it looks like the last commit was in 2019. If you're using nightmare to render website screenshots, I would encourage you to move to either puppeteer or playwright, in order to automate the most recent browsers. Of course, you can also try Urlbox's [screenshot API](https://urlbox.com/screenshot-api.md) out too if you don't want the hassle of maintaining your own microservice. ## Website screenshots with Phantom.js [Phantom.js](https://github.com/ariya/phantomjs) was the original headless web browser that could be automated with JavaScript. It uses QtWebkit as the rendering engine. Development on the project has been suspended and it is recommended to upgrade any microservice that uses phantom.js to either puppeteer or playwright. Let's see if the nytimes.com screenshot can be generated with phantom.js: First we need to install phantom.js: ```zsh npm install phantomjs-prebuilt ``` Since phantomjs is a standalone binary and not a node specific package, it cannot be run directly from node. Instead you either run the binary directly, or use node's child process API's to spawn a new process and run phantomjs that way. For ease of use, we will run the phantomjs binary directly. We just need to pass it a script to run. Here is our phantom.js script: ```js var page = require("webpage").create(); page.open("http://nytimes.com/", function () { page.viewportSize = { width: 1280, height: 1024 }; page.clipRect = { top: 0, left: 0, width: 1280, height: 1024 }; page.render("nyt-phantom.png"); phantom.exit(); }); ``` By default, phantom.js will try to take a full page screenshot, whereas we just want the visible viewport portion of the page. This is why we've explicitly defined the page's `viewportSize` and `clipRect` properties in the above script. Save the above code to a file called `phantom-screenshot.js` and run it: ```zsh ./node_modules/phantomjs-prebuilt/bin/phantomjs phantom-screenshot.js ``` It should capture the screenshot to the file `nyt-phantom.png`: ![screenshot of nytimes generated by phantom](/content/screenshots-javascript/nyt-phantom.png) It seems like we've been able to successfully generate a screenshot of nytimes.com with phantom.js. It looks asthough the version of nytimes.com that we have rendered is one with no javascript enabled, and therefore no ads or cookie banners! This must be because it detected the QTWebkit-based phantomjs browser as being out of date, and chose to serve us a simplified version of their page. ## Urlbox website screenshot API [Urlbox](https://urlbox.com/.md) is a [screenshot API](https://urlbox.com/screenshot-api.md) that can be used to generate website screenshots and PDFs from URLs. It is built on top of puppeteer and there is an [npm package for taking screenshots](https://www.npmjs.com/package/urlbox) available for node.js. You may want to try out urlbox if you are getting frustrated spending a lot of time maintaining your own screenshot or URL to PDF rendering microservice. There is a 7-day free trial and prices start at $19 per month. We render millions of screenshots and PDFs every month and handle 100's of headless chrome instances in parallel at scale. There are plenty of options to allow you to render [full page screenshots](https://urlbox.com/docs/options.md#full_page), hide cookie banners and block ads from screenshots or use a [proxy](https://urlbox.com/docs/options.md#proxy) to prevent being blocked by sites. The documentation for the API can be found at [urlbox.com/docs](https://urlbox.com/docs/.md). First let's install the urlbox package from npm. So that we can download the screenshot from urlbox we will also install the http request library, `got`: ```zsh npm install urlbox got ``` To authenticate with the Urlbox API, we'll need to signup and retrieve our API key and secret, then pass them to the `urlbox` package: ```js const got = require("got"); const fs = require("fs"); const Urlbox = require("urlbox"); const urlbox = Urlbox(YOUR_API_KEY, YOUR_API_SECRET_KEY); // generate the https://api.urlbox.com/v1/key/png?url=... url const imgUrl = urlbox.generateRenderLink({ url: "nytimes.com" }); // request the urlbox url and save the response to nyt-urlbox.png got(imgUrl) .buffer() .then((response) => { fs.writeFileSync("nyt-urlbox.png", response, "binary"); }); ``` Let's run this script and wait for the screenshot to be downloaded: ```zsh node urlbox-screenshot.js ``` Here is the resulting screenshot, `nyt-urlbox.png`: ![screenshot of nytimes generated by urlbox](/content/screenshots-javascript/nyt-urlbox.png) Immediately we can see that the ad is showing at the top. In order to get rid of this we can enable the ad-blocker by passing in the `block_ads` option to urlbox: ```js {8} const got = require("got"); const fs = require("fs"); const Urlbox = require("urlbox"); const urlbox = Urlbox(YOUR_API_KEY, YOUR_API_SECRET_KEY); const imgUrl = urlbox.generateRenderLink({ url: "nytimes.com", block_ads: true, }); got(imgUrl) .buffer() .then((response) => { fs.writeFileSync("nyt-urlbox-noads.png", response, "binary"); }); ``` Running the script with the [`block_ads`](https://urlbox.com/docs/options.md#block_ads) option set to true should result in a screenshot without the ad showing: ![screenshot of nytimes generated by urlbox with no ads](/content/screenshots-javascript/nyt-urlbox-noads.png) We can see that the ad is no longer loading, as it is now being blocked by Urlbox, but the container is still showing which is taking up a significant portion of our screenshot with blank space. In order to get rid of this we can tell urlbox to scroll down to the first element below the ad. We can pass in the [`scroll_to`](https://urlbox.com/docs/options.md#scroll_to) option with a value of `#app > div:nth-child(2)`. This tells urlbox to scroll to the second div in the page underneath the #app div before taking a screenshot, effectively scrolling the top ad container out of view. ```js {9} const got = require("got"); const fs = require("fs"); const Urlbox = require("urlbox"); const urlbox = Urlbox("NFNjOcVieiP3dXx5", "7d85bd59e48f49e0b50029e1797cf1a8"); const imgUrl = urlbox.generateRenderLink({ url: "nytimes.com", block_ads: true, scroll_to: "#app > div:nth-child(2)", }); got(imgUrl) .buffer() .then((response) => { fs.writeFileSync("nyt-urlbox-noads-scrolled.png", response, "binary"); }); ``` Now if we inspect the resulting screenshot, we see the ad container is no longer showing: ![screenshot of nytimes generated by urlbox with no ads and scrolled](/content/screenshots-javascript/nyt-urlbox-noads-scrolled.png) This just demonstrates how easy it is to get the perfect screenshot using the urlbox API and it's many [options](https://urlbox.com/docs/options.md). ## Conclusion In this article we have seen how to generate website screenshots in node.js using a variety of different tools. We would recommend using puppeteer or playwright to capture website screenshots as they are both well supported and give you the ability to use the most recent browsers. Electron could be used but it is primarily a development platform for building cross-platform desktop applications and so using it to take screenshots can feel quite clunky and is not a primary use-case. Nightmare.js and Phantom.js are no longer being maintained and therefore not recommended. If you want to quickly add website screenshots or PDFs to your project without all the hassle of maintaining your own screenshot service, and having to deal with all of the edge-cases that go along with that, we recommend using a screenshot API such as urlbox. Perhaps you already spend many frustrated hours maintaining a screenshot microservice that is constantly breaking - running out of memory, or generating inaccurate screenshots?

We've been rendering for more than 10 years, and so have a wealth of experience ironing out interesting edge cases, often with E-Commerce sites. Recently I found that when trying to render a particular site with our `full_page` option, our renderer couldn't find an element at the top of the page. I thought I understood the DOM–until I found its Shadow. *** ## The Issue One challenge when capturing a screenshot in full-page mode is simulating a natural scrolling experience while avoiding the inclusion of sticky elements that should move with the page. Our approach ensures that elements fixed to the top (e.g., menu banners) remain at the top, while those positioned at the bottom (e.g., chatbot buttons, back-to-top buttons) stay anchored at the bottom. We do this by taking many screenshots, then 'stitching' them together. Here's more information on our full-page 'modes'. The site that caused us an issue showed the following during a 'stitch' style full page render: As we approach our second shot which we intend to stitch to the first, the sticky banner is still visible, resulting in a strange looking screenshot with a duplicated banner! ## Investigating Like any good developer, I opened Chrome DevTools and started inspecting the HTML. After replicating the issue locally, I noticed that the list of fixed elements we find and perform business logic on did not include the culprit. I found some strangely named HTML elements, I had never heard of a `` before... I realised it was a custom element, with a shadow DOM inside of it. In short, the Shadow DOM is like a hidden layer of the DOM where elements can exist separately from the main document while still being attached to it. The shadow root serves as the entry point to this hidden layer and is attached to a shadow host—the visible element in the main DOM that contains the shadow root. The Shadow DOM can be created in either open or closed mode: - Open: The shadow root can be accessed using `shadowHostElement.shadowRoot` from JavaScript. - Closed: The shadow root is inaccessible from outside the component. In this case our host is ``, our shadow root lives inside of it `#shadow-root (open)`, and our culprit is a fixed position div inside of it. For a deeper understanding which includes what `` elements are, check out MDN's explanation. ## Solution Fortunately, this banner’s Shadow DOM is open, as indicated by `#shadow-root (open)` in the screenshot above. This means we can access its elements using JavaScript. Now, let’s say you’re filtering elements to find those with position: fixed, but you also need to account for elements inside an open Shadow DOM—like in this example. You can do that by simply retrieving all shadow DOM elements before applying your filter: ```ts let shadowDomElements: Element[] = []; allElements .filter((element) => element.shadowRoot) .forEach((element) => { shadowDomElements = [ ...shadowDomElements, ...(element.shadowRoot?.querySelectorAll("*") || []), ]; }); ``` This collects all elements within shadow roots across the page. Including these in our list of fixed elements solved the issue immediately. ## Conclusions The Shadow DOM really isn’t as mystical as it seems—it’s just another tool for building reusable components while abstracting logic. However, when working with automation tools like Puppeteer, it introduces an extra layer of complexity that can lead to unexpected rendering issues if not accounted for. In cases like this, where elements are hidden inside an open shadow root, simply expanding your element selection to include shadow DOM children can resolve the issue. However, if the shadow root is closed, things get trickier, as there’s no direct way to access its contents through JavaScript. This experience reinforced a valuable lesson: even when you think you fully understand the DOM, there’s always something new lurking in the shadows. ## Taking Screenshots the easier and more reliable way At Urlbox, we've already worked through the headaches you might be facing when trying to take screenshots of websites, HTML and PDFs.

This can help speed up the page load time and reduce the amount of data that needs to be downloaded. This is especially useful when using a proxy server to scrape pages, as it can reduce the amount of bandwidth used, and therefore reduce the overall cost of your proxy per page scraped. ## Using request interception naïvely The easiest way to block images with puppeteer is using the built in request interception feature. Once request interception is turned on, every request will stall unless it's continued, responded or aborted. Here's a naïve example of blocking image requests with puppeteer (don't use this in production!): ```js title="puppeteer-block-images.js" import puppeteer from "puppeteer"; const browser = await puppeteer.launch({ headless: false, }); const page = await browser.newPage(); await page.setRequestInterception(true); page.on("request", (request) => { if (request.resourceType() === "image") { console.log("Blocking image request: " + request.url()); request.abort(); } else { request.continue(); } }); await page.goto("https://urlbox.com"); await page.setViewport({ width: 1280, height: 3000 }); await page.screenshot({ path: "./urlbox.png" }); await browser.close(); ``` When this script is run, the output on the command line will look similar to: ```bash $ bun puppeteer-block-images.js Blocking image request: data:image/svg+xml;charset=utf-8,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 800 600'%3E%3Cfilter id='b' color-interpolation-filters='sRGB'%3E%3CfeGaussianBlur stdDeviation='20'/%3E%3CfeColorMatrix values='1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 100 -1' result='s'/%3E%3CfeFlood x='0' y='0' width='100%25' height='100%25'/%3E%3CfeComposite operator='out' in='s'/%3E%3CfeComposite in2='SourceGraphic'/%3E%3CfeGaussianBlur stdDeviation='20'/%3E%3C/filter%3E%3Cimage width='100%25' height='100%25' x='0' y='0' preserveAspectRatio='none' style='filter: url(#b);' href='/images/screenshots/stripe-desktop.jpg'/%3E%3C/svg%3E Blocking image request: data:image/svg+xml;charset=utf-8,%3Csvg xmlns='http://www.w3.org/2000/svg' %3E%3Cfilter id='b' color-interpolation-filters='sRGB'%3E%3CfeGaussianBlur stdDeviation='20'/%3E%3CfeColorMatrix values='1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 100 -1' result='s'/%3E%3CfeFlood x='0' y='0' width='100%25' height='100%25'/%3E%3CfeComposite operator='out' in='s'/%3E%3CfeComposite in2='SourceGraphic'/%3E%3CfeGaussianBlur stdDeviation='20'/%3E%3C/filter%3E%3Cimage width='100%25' height='100%25' x='0' y='0' preserveAspectRatio='xMidYMid slice' style='filter: url(#b);' href='https://pbs.twimg.com/profile_images/1478327435041153034/gfkjGjQF_400x400.jpg'/%3E%3C/svg%3E Blocking image request: https://urlbox.com/_next/image?url=https%3A%2F%2Fpbs.twimg.com%2Fprofile_images%2F1883092999%2FScreen_Shot_2012-03-09_at_1.12.00_PM_400x400.png&w=1920&q=75 ... ``` This puppeteer script is blocking all image requests, including `data:image/svg+xml` images that are loaded via CSS. This will lead to a great saving in bandwidth. Let's see the resulting screenshot to show the images that were blocked: ![Screenshot of urlbox.com with images blocked](/content/puppeteer-block-images/urlbox-images-blocked.png) You'll notice that the images look broken because of the image requests being blocked. However, the brand logos and some icons are still visible in the screenshot. This is because the brand logos are inline SVG embedded inside the HTML document, and not loaded via an image request. ## The trouble with request interception If you are using puppeteer to do web scraping, it is likely that you're also going to be using a third party package that also wants to intercept requests. Examples of third party packages that hook into puppeteer to intercept requests are: - adblockers, such as [@cliqz/adblocker](https://github.com/ghostery/adblocker) - resource blockers, such as [puppeteer-extra-plugin-block-resources](https://github.com/berstend/puppeteer-extra/tree/master/packages/puppeteer-extra-plugin-block-resources) If you naïvely handle request interceptions like above whilst using third party libraries that also want to intercept requests, you will likely run into problems. The main problem will be that puppeteer will raise a `Request is already handled!` exception if you try to `continue`, `abort` or `respond` to a request that has already been handled by another library. Further problems could result in certain requests getting stalled, causing timeouts when navigating to certain URL's. ### Being aware of multiple request interception handlers These problems can be guarded against by always assuming that you are not the only one intercepting requests. Let's rewrite the request interception handler above to be more robust: ```js title="puppeteer-block-images-defensive.js" page.on("request", (request) => { if (request.isInterceptResolutionHandled()) { return; } if (request.resourceType() === "image") { console.log("Blocking image request: " + request.url()); request.abort(); } else { request.continue(); } }); ``` We added the `request.isInterceptResolutionHandled()` check to ensure that the request hasn't already been handled by another handler before we handle it. This prevents us from receiving the `Request is already handled!` exception and shields us from other bugs. ### Multiple *async* request interception handlers Handlers can also be async, and the value of `request.isInterceptResolutionHandled()` is only safe to use in the same synchronous code block as where you call `request.continue/abort/respond`. If you are awaiting an asyncronous operation as part of your request interception handler, you need to ensure that you always call `request.isInterceptResolutionHandled()` in the same synchronous context before going on to call `abort/continue/respond`. Let's see an example of this: ```js title="multiple-async-interception-handlers" page.setRequestInterception(true); // first async handler page.on('request', async (request) => { // request hasn't been handled here so will continue.. if (request.isInterceptResolutionHandled()) return; await sleep(5000); // we need to check again here because the request // might have been handled by the handler below while we were awaiting the sleep if (request.isInterceptResolutionHandled()) return; await request.continue(); }); // second async handler (this could be somewhere in a third party library) page.on('request', async (request) => { if (request.isInterceptResolutionHandled()) return; await sleep(3000); // once again we check here because the request // may have been handled while we were awaiting the sleep if (request.isInterceptResolutionHandled()) return; await request.continue(); }) ``` ### Using co-operative request intercept mode [Co-operative request interception](https://pptr.dev/guides/request-interception/#cooperative-intercept-mode) is a way for multiple libraries to intercept requests in a way where they do not compete with each other and with your own puppeteer script. Using co-operative request interception requires passing a `priority` into the `request.abort`, `request.continue` or `request.respond` methods as the second argument. The default priority is `0`, and the method that gets called with the highest priority wins. However, if any one handler does not pass a priority into the `abort/continue/respond` methods, then it will prevail, so it's important to check the source code of any third party packages that are doing request interception to ensure they have been updated to use co-operative request interception before relying on it. Here's an example of how co-operative request interception works: ```js title="puppeteer-cooperative-request-interception.js" page.setRequestInterception(true); // first handler page.on('request', (request) => { if (request.isInterceptResolutionHandled()) return; await request.continue({},1); }); // second handler (this could be somewhere in a third party library) page.on('request', (request) => { if (request.isInterceptResolutionHandled()) return; await request.abort({},2); }) ``` In the above example, the second handler will always win, and the request will be aborted because `abort`'s priority of 2 is greater than `continue`'s priority of 1. ## Using the chrome devtools protocol directly to block images with puppeteer It's also possible to drop down a level of abstraction and use the underlying chrome devtools protocol (CDP) in order to start intercepting requests. First, we need to get a handle to a CDP session and enable the `Fetch` domain. The fetch domain allows us to substitute the browser's network layer with our own custom code. When enabling the fetch domain, we pass in a `urlPattern` which filters the requests that we want to intercept based on their URL. In our example, we want to intercept all requests, so we use the wildcard `*` as the `urlPattern`. ```js title="puppeteer-block-images-cdp.js" const client = await page.target().createCDPSession(); await client.send("Fetch.enable", { //see: https://chromedevtools.github.io/devtools-protocol/tot/Fetch#type-RequestPattern // handleAuthRequests: true, patterns: [ { urlPattern: "*", requestStage: "Request", }, ], }); ``` Next we need to setup an event handler for the `Fetch.requestPaused` event. This event gets fired when a request matching the `urlPattern` is received. Within this event handler function, we run custom code to decide what to do with each individual request. As this post is about blocking image requests, we'll check the `resourceType` of the request and if it's an `Image`, we can abort the request. ```js //see: https://chromedevtools.github.io/devtools-protocol/tot/Fetch#event-requestPaused client.on("Fetch.requestPaused", async (event: any) => { const { request, resourceType } = event; const { url, method } = request; if(resourceType === "Image") { console.log("Blocking image request: " + url); await client.send("Fetch.failRequest", { requestId, errorReason: "BlockedByClient", }); return; } await client.send("Fetch.continueRequest", { requestId, }); }); ``` Running this will give us the same behaviour as the request interception examples above. We could also check for other resource types here, such as fonts, scripts and stylesheets and decide to block those too, as this will save us extra bandwidth. --- # Execution context was destroyed, most likely because of a navigation - Puppeteer > Encountering the “Execution context was destroyed, most likely because of a navigation.” error in Puppeteer? This guide explains why it happens and how to fix it. Source: https://urlbox.com/puppeteer/execution-context-destroyed Last updated: 2025-03-14 --- ## **TL;DR** ### **Why does the error happen?** - .click() fires but **does not wait for navigation**. - If a navigation occurs, the execution context is **destroyed**. - Puppeteer **tries to execute evaluate() too soon**, causing an error. ### **How do we fix it?** - Use **await page.waitForNavigation()** to ensure Puppeteer waits until the new page loads. - If navigation isn’t certain, use **await page.waitForSelector()** instead. *** ## Why Does This Happen? If you've used Puppeteer to interact with a webpage, you've probably encountered this error at some stage: `Error: Execution context was destroyed, most likely because of a navigation.` This typically happens when Puppeteer tries to execute JavaScript on a page that is no longer available—usually because the page navigated away (and so the execution context for it is destroyed). Let’s break down why this occurs and how to fix it. Consider the following Puppeteer script: ```javascript await page.click('a#navigate-away'); await page.evaluate(() => document.title); ``` Here’s what’s happening: 1. **`page.click()` fires immediately**, telling the browser to interact with the element. 2. If the clicked link **triggers a page navigation**, the old page starts unloading. 3. **Before the new page fully loads, Puppeteer tries to execute `evaluate()`**. 4. But by then, the old execution context is gone, causing the error. It's very easy to assume that the most trivial calls with Puppeteer are exempt from this issue. You'll find that the most 'harmless' calls can cause the most harmful failures. Some 'harmless' examples which still require a stable execution context include: - `page.url()` - `page.title()` - `page.content()` Notice that these are merely read only actions. Just imagine that every time you call Puppeteer to do something, you’re making a `fetch()` request that could fail unpredictably. Just like you’d wrap a network request in try/catch to handle timeouts or errors, you should assume that any Puppeteer call—no matter how harmless it looks—might fail due to navigation, execution context loss, or frame detachment. ## How to Fix It Ensure Puppeteer waits for the navigation to complete before executing further JavaScript. ### Solution 1 : Use `waitForNavigation()` Instead of running `.click()` and immediately continuing, we can use Puppeteer's `.waitForNavigation()` method: ```javascript await Promise.all([ page.waitForNavigation({ waitUntil: ['domcontentloaded', 'networkidle2'] }), page.click('a#navigate-away') ]); await page.evaluate(() => document.title); // Now safe to execute ``` Check this out in the Puppeteer docs. The `page.waitForNavigation` method takes (optional) options, which allow you to `waitUntil` certain life-cycle events occur on the page, add a timeout, or a signal to cancel the call. Take a look at the different lifecycle events here. ### Solution 2: Wait for an Element Instead If you're not sure whether navigation will happen or not, you can wait for an element unique to the new page to exist in the DOM: ```javascript await page.click('a#navigate-away'); await page.waitForSelector('h1'); // Ensures new content is loaded await page.evaluate(() => document.title); ``` Check this out in the Puppeteer docs This is more useful for sites that A/B test, where clicking or scrolling may cause a navigation sometimes but not every time. It's also handy for single page applications or modals that may change the DOM but not navigate away. ## Taking Screenshots the easier and more reliable way At Urlbox, we've already worked through the headaches you might be facing when trying to take screenshots of websites, HTML and PDF's.

Source: https://urlbox.com/puppeteer/viewport-and-drawers Last updated: 2025-04-07 --- We are specialists at taking automated screenshots. We've been rendering for more than 10 years and have extensive experience ironing out tricky edge cases, often with E-Commerce sites. This time we found a visual quirk when rendering a website with Puppeteer that ended up displaying a shopping cart drawer element across the entire page. *** ## The Problem When trying to render this page, we got a strange side effect: The first thing I noticed when I visit the site using chrome, was that the shopping cart doesn't come up by default. Something in our rendering engine must have thought it an element which needed clicking or re-styling. I also noticed that the shopping cart opens to the right, but the screenshot shows it snapped to the left... The Urlbox rendering engine has a few mechanisms for clicking elements on the page. These are performed in order to hide modals, click on cookie banners, and, for full page screenshots, hide fixed elements or make them absolute on the page while scrolling. We use more heuristic logic to find these elements that have characteristics of the elements we look for. Here's the element in question: And it's computed style: We take some `position: fixed;` elements and make them `position:absolute;`. This allows those elements like a navbar/menu or chatbot to stay on the page but not scroll with the page as the screenshot is taken, causing them to appear duplicated rather than at the top/bottom of the page. This logic was finding this drawer element and accidentally including it in a list of elements that needed `position:absolute`, causing the element to stick to the left of the DOM. If it included this type of element in the list for this site, then it could possibly do the same for other sites! ## The Solution I noticed that when closing the shopping cart, the computed style would add an X transformation to the element to place it out of the viewport, so to fix this and sites like it, we added some simple logic as a filter, to identify when a fixed element is likely to be a drawer, and not position it differently. Here's an example: ```JS function isTransformedOutOfView(elem: HTMLElement): boolean { // Get the Element and viewport width const width = elem.clientWidth; const viewportWidth = window.innerWidth || document.documentElement.clientWidth; // Find out if there's a transform on the element const transform = getComputedStyle(elem).transform; // If there's no transform, or it's 'none', the element is not transformed out of view if (!transform || transform === "none") { return true; } // Check if the transform is a matrix transformation // The matrix CSS method is as such: matrix(scaleX(), skewY(), skewX(), scaleY(), translateX(), translateY()) const matrixMatch = transform.match(/matrix\(([^)]+)\)/); if (matrixMatch) { // Extract the matrix values and parse them as numbers const values = matrixMatch[1].split(",").map(Number); const transformX = values[4]; // Get the element's position relative to the viewport const rect = elem.getBoundingClientRect(); // Return false if the element is fully translated off-screen horizontally return !( (rect.right === 0 && width === transformX) || (rect.left === 0 && width === -transformX) || rect.left === viewportWidth || rect.right === -viewportWidth ); } return true; } ``` The purpose of this function is to check that the element has a transformation on it horizontally (X). If it does and the element is fixed to the right, it would likely be a closed drawer if it's been transformed by its width, or in other words if `width === transformX`. Positive transformations are to the right and negative to the left. This is why if the element is fixed to the left of the viewport, we invert the X transformation `width === -transformX`, because we need to turn a negative transformation number into a positive to compare the element's width to it. This is a good starting point for detecting fixed elements on the page, but there are a number of things one could do to improve this: 1. Add some room/play for rough pixel differences between the transformation and width instead of a direct `===` check. This would account for other attributes which unexpectedly affect the element's size (margin/border etc). 2. Check for vertical drawers too, like this. 3. Don't just check for a drawer made with transform, but also check the other ways that a developer could code in a slide-over/drawer, such as setting width or top/right/left/bottom on click. ## Taking Screenshots the easier and more reliable way By taking care to identify and filter out drawer-like elements from our list of candidates for `position: absolute`, we ensure a more accurate and visually correct rendering of full-page screenshots. This is just one of many niche quirks we come across every day to refine our engine, so it can continue to take the millions of reliable screenshots it already has.

Source: https://urlbox.com/puppeteer-wait-for-page-load Last updated: 2022-09-19 --- Knowing when a page has finished loading is a crucial first step to taking accurate website screenshots with puppeteer. Taking a screenshot before the page has fully loaded will result in a bad screenshot where images are not loaded and styles have not been parsed and applied. Waiting for too long after the page is loaded, means we are wasting unneccessary time and causing the screenshot request to take longer than is required. Striking the right balance between the page being fully loaded and getting a quick screenshot is quite a challenge when it is applied generally to any website. In general, there is no one size fits all solution, and usually different websites require different strategies. Below we describe a few different strategies to determine when a page has fully loaded. ![domcontentloadedvsload](/content/wait-for-pageload/domcontentloadedvsload.png) ## How to know when a Page is loaded in Puppeteer Puppeteer gives us four events we can wait on to detect when a page has loaded. We can access these options via the `waitUntil` option that we pass to [`page.goto`](https://pptr.dev/api/puppeteer.page.goto). We could also use a call to [`page.waitForNavigation`](https://pptr.dev/api/puppeteer.page.waitfornavigation) and wait for these events to fire. ### `waitUntil: domcontentloaded` The `domcontentloaded` option will fire the earliest, and is the equivalent of waiting for the [`DOMContentLoaded`](https://developer.mozilla.org/en-US/docs/Web/API/Document/DOMContentLoaded_event) event on the `document`: ```js document.addEventListener("DOMContentLoaded", (event) => { console.log("DOM fully loaded and parsed"); }); ``` It fires when the initial HTML document's DOM has been loaded and parsed. However, this does NOT wait for stylesheets, images, fonts and subframes to finish loading. This means for taking accurate screenshots, it is not a good choice as there is a high chance that a screenshot may be taken before images and styles have had a chance to load and be applied to the web page. Here's an example of using `domcontentloaded`: ```js const browser = await puppeteer.launch({ devtools: true, defaultViewport: { width: 1280, height: 1024, }, headless: false, }); const page = await browser.newPage(); console.time("goto"); await page .goto("https://twitter.com/jot", { waitUntil: "domcontentloaded", }) .catch((err) => console.log("error loading url", err)); console.timeEnd("goto"); await page.screenshot({ path: `twitter-domcontentloaded.png` }); await browser.close(); ``` When I ran this,the `goto` step took 764ms until the domcontentloaded event fired. The resulting screenshot is: As you can see, the page is just showing the twitter logo in the centre of the screen, so this screenshot has been taken too early. If we change the url to bbc.co.uk, we get the following screenshot: This took 1.9s for the `goto` step to complete. In this screenshot of bbc.co.uk, we have a bit more of the DOM structure, and the styles have (suprisingly) been applied, however because `domcontentloaded` doesn't wait for other resources, the images have yet to load in this screenshot. ### `waitUntil: load` The `load` option fires when the whole page has loaded, including all dependent resources such as stylesheets, fonts and images. It is equivalent to waiting for the `load` event on the window: ```js window.addEventListener("load", (event) => { console.log("page is fully loaded"); }); ``` Let's change the example above to wait for the `load` event: ```js ... console.time("goto"); await page .goto("https://twitter.com/jot", { waitUntil: "load", }) .catch((err) => console.log("error loading url", err)); console.timeEnd("goto"); await page.screenshot({path: `twitter-load.png` }); ... ``` This time, the `goto` step took 716ms, and the screenshot is identical: As you can see, there is little change in the screenshot of twitter. Why is that? It is most likely because the initial HTML that twitter sends does not include direct links to resources such as images, therefore the page load event just fires when the initial DOM has been parsed, which for twitter is really early on. Twitter relies on the browser to parse and load a big javascript bundle. Only once the browser has finished evaluating the javascript and constructed the DOM, will then be directed to load further resources such as images, videos, stylesheets and webfonts. Let us try `bbc.co.uk` again, and compare with the previous screenshot: bbc.co.uk - `domcontentloaded`, 1.9s, images not loaded bbc.co.uk - `load`, 4.36s, images are loaded This time, the `load` event took 4.36s to fire and has meant that bbc's images have all loaded. It also gave enough time for the site to render a cookie banner at the top - great 😝 ## When `load` is not enough You might think that using the `load` event would be fine and the problem is solved, and you'd be almost correct - for *traditional* websites the `load` event should be fine. However, there are of course a large and growing percentage of websites that act differently. These sites will continue to load parts or even the majority of the page, after the `load` event has fired. The classic example is a single page app (or SPA for short) that returns a slim initial HTML document, and relies on the browser to download and parse a load of javascript and then construct the completed webapp. This is exactly how the twitter.com site works. The initial body HTML for a single page app might be something as bare bones as: ```html Some title
``` This kind of lean initial document will cause the `domcontentloaded` and `load` events to fire very quickly. In this case, a screenshot taken after those events fire, will result in a screenshot of an incomplete loading page with images, styles and even part of the final DOM still not in place. Just like we have seen with our twitter.com screenshots above. This is where Puppeteers `networkidle0` and `networkidle2` can help. ### `waitUntil: networkidle0` When passing `networkidle0`, puppeteer will wait for there to be no network activity for at least 500ms. This works well for SPAs that load resources after parsing a javascript bundle or with `fetch` requests. When you first open a tweet on twitter.com, you can see the initial HTML document is tiny, and nothing like what the completed page looks like. You can see the initial HTML payload that gets sent from twitters server by viewing the page source in your browser. You'll also notice that there is a loading spinner which takes quite a while to load additional content such as the actual tweet content. Using `networkidle0` on a site like twitter, will ensure that the screenshot is not taken until there is at least 500ms between any network requests. This should usually be good enough to allow all of the additional requests that twitter.com makes to complete before the event fires. Let's change the example to wait until `networkidle0` is fired: ```js ... console.time("goto"); await page .goto("https://twitter.com/jot", { waitUntil: "networkidle0", }) .catch((err) => console.log("error loading url", err)); console.timeEnd("goto"); await page.screenshot({path: `twitter-networkidle0.png` }); ... ``` This time the `goto` step took 5.94s, and the screenshot looks like: ### `waitUntil: networkidle2` There is a chance that when using `networkidle0` the event may never fire, because the site is always busy with some network activity. This could be long polling, or high frequency analytics tracking over websockets. Another option is to use `networkidle2`, which allows no more than 2 active network requests for a window of 500ms. This means that if a site is constantly pinging a server, but there are only 2 network requests active, the event will still fire. Switching to `networkidle2` for our twitter example doesn't yield any difference in the screenshot, and the time taken was 5.99s, however for some websites, it may reduce the amount of time needed to wait compared with `networkidle0`. ## using `Page.waitForNetworkIdle()` to customise the idle timeout Whilst `networkidle0` and `networkidle2` options are hard coded to buffer for 500ms between network requests, Puppeteer does have an option that allows you to wait a custom amount of time for the network to be idle. The [`Page.waitForNetworkIdle()`](https://pptr.dev/api/puppeteer.page.waitfornetworkidle/) method takes an `idleTime` option which allows you to specify a custom amount of time in milliseconds to wait for the network to be completely idle. This is equivalent to setting `networkidle0` but instead of waiting for 500ms, we can now tell puppeteer to wait for `idleTime` ms. Since we need to make a separate call in order to use the `waitForNetworkIdle` method, we can set the initial `waitUntil` option of the `page.goto` to `domcontentloaded`, which should fire early, and then wait for network idle. We use `Promise.all` to wait for both promises to resolve. : ```js await Promise.all([ page.goto("https://twitter.com/jot", { waitUntil: "domcontentloaded", }), page.waitForNetworkIdle({ idleTime: 250 }), ]); ``` ## use `Page.waitForSelector()` to wait for an element to be present, visible, absent or hidden In some cases the previous options that rely on browser load events, and network activity will not work reliably. For example, if you're trying to take a screenshot of a chart in a dashboard that takes a while to load data from the server (looking at you [powerbi](https://powerbi.microsoft.com/en-gb/) 😜), and then render it to the screen, a good option is to wait for a specific element that you know will be present in the DOM when the chart or page has fully loaded. We can use `Page.waitForSelector()` like so, the `{visible: true}` option tells Puppeteer to wait for the element to be present in the DOM *and* not to have `display:none` or `visibility:hidden` css properties: ```js await Promise.all([ page.goto("https://twitter.com/jot", { waitUntil: "domcontentloaded", }), page.waitForSelector(".page-loaded", { visible: true }), ]); ``` We can also use this method to wait for an element to NOT be in the DOM, or to be hidden, by passing the `{ hidden: true }` option. This could be useful if you know that you don't want to take a screenshot until a certain element has left the DOM, for example waiting for a loading spinner to leave: ```js await Promise.all([ page.goto("https://twitter.com/jot", { waitUntil: "domcontentloaded", }), page.waitForSelector(".loading-spinner", { hidden: true }), ]); ``` Note that if your selector refers to multiple instances, for example, you want to wait for *all* loading spinners to be hidden in the DOM, then this method will only wait for the first element that it finds. Also, if your element happens to be inside a sub frame of the page, and not in the main frame, Puppeteer won't find it, and most likely the call will end up timing out. Urlbox's equivalent options do take these edge cases into account and will check in all iframes of the page for the selector, and also use `document.querySelectorAll(selector)` to query for the selector. Puppeteers [`waitForXPath`](https://pptr.dev/api/puppeteer.page.waitforxpath) is a similar function that takes an XPath expression instead of a css selector, to identify an element. ## Wait for frame / request / response If you know that a certain website will have fully loaded once it receives a specific request or response, you can use Puppeteers, [waitForRequest](https://pptr.dev/api/puppeteer.page.waitforrequest) and [waitForResponse](https://pptr.dev/api/puppeteer.page.waitforresponse) methods. These take either a url, or a function that takes an [HTTP Request](https://pptr.dev/api/puppeteer.httprequest) (or [HTTP Response](https://pptr.dev/api/puppeteer.httpresponse)) and allows you to run your own predicate function on it, such as matching a regex. ```js await Promise.all([ page.goto("https://example.com", { waitUntil: "domcontentloaded", }), page.waitForRequest("https://example.com/some/resource"), ]); ``` example using `waitForResponse` with predicate function: ```js await Promise.all([ page.goto("https://example.com", { waitUntil: "domcontentloaded", }), page.waitForResponse( (response) => response.url().match(/example.com/) && response.text().includes("") ), ]); ``` Similarly, if a page contains many frames, and you only care when a certain frame has loaded, you can use the [`page.waitForFrame`](https://pptr.dev/api/puppeteer.page.waitforframe) function which also takes either a url, or a predicate function with [Frame](https://pptr.dev/api/puppeteer.frame/) as argument: ```js await Promise.all([ page.goto("https://example.com", { waitUntil: "domcontentloaded", }), page.waitForFrame( (frame) => frame.url().match(/example.com/) || frame.name() == "myframe" ), ]); ``` ### Wait for a function You can use [`page.waitForFunction()`](https://pptr.dev/api/puppeteer.page.waitforfunction) to run a function in the context of the website that will determine whether or not the page has loaded. ```js await page.waitForFunction("renderingCompleted === true"); ``` ### Using MutationObserver to wait for the DOM to settle The trouble with a lot of the `waitFor*` functions are that they require specific knowledge about the site upfront. For example, you either need to identify an element on the page to wait for, or a particular request. What happens if you want a reliable way to know when *any* site has finished loading? Unfortunately, such a function does not exist that guarantees a site is loaded, for all sites on the web. If it did exist, then Puppeteer, and all other browsers, would provide it. However, one strategy that can give a good indication, without needing to know anything specific about the site, is to listen to changes to the DOM and, similarly to the `networkidle` events, fire an event when the DOM has been 'idle' for a certain amount of time. To do this, we can make use of puppeteers [`page.evaluate`](https://pptr.dev/api/puppeteer.page.evaluate) function, to run code inside the page context, and gain access to the DOM's native [`MutationObserver`](https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver). According to MDN, the `MutationObserver` *provides the ability to watch for changes being made to the DOM tree*. Sounds useful for our use case. When you setup a MutationObserver, you pass it a root element and a callback function, where any changes to the root elements subtree, such as insertion or deletion of DOM elements, or changing of attributes, will fire the observers callback function. We cannot assume that `document.body` will exist on every website, so we can use `document.body || document.documentElement` as the root element. Within the mutation observers callback function, we can use a debounced function that will only resolve our promise once it has *not* been called for a certain amount of time. Here is an example `waitForDOMToSettle` function that could be waited on alongside `page.goto` and other wait functions. The method will wait for the DOM to be idle for 1 second and timeout after 30 seconds. ```js const waitForDOMToSettle = (page, timeoutMs = 30000, debounceMs = 1000) => page.evaluate( (timeoutMs, debounceMs) => { let debounce = (func, ms = 1000) => { let timeout; return (...args) => { console.log("in debounce, clearing timeout again"); clearTimeout(timeout); timeout = setTimeout(() => { func.apply(this, args); }, ms); }; }; return new Promise((resolve, reject) => { let mainTimeout = setTimeout(() => { observer.disconnect(); reject(new Error("Timed out whilst waiting for DOM to settle")); }, timeoutMs); let debouncedResolve = debounce(async () => { observer.disconnect(); clearTimeout(mainTimeout); resolve(); }, debounceMs); const observer = new MutationObserver(() => { debouncedResolve(); }); const config = { attributes: true, childList: true, subtree: true, }; observer.observe(document.body, config); }); }, timeoutMs, debounceMs ); ``` Let's try it out with the twitter.com url from before. Note that we don't use `Promise.all` here to run both functions in parallel, because for the `waitForDOMToSettle` function to work properly, we need to have established that the DOM has loaded, hence we run this function *after* `page.goto` has resolved with the `waitUntil` option set to `domcontentloaded`: ```js ... console.time("goto"); await page.goto("https://twitter.com/jot", { waitUntil: "domcontentloaded", }); await waitForDOMToSettle(page); console.timeEnd("goto"); ... ``` Here, the goto step took 9.4seconds, and the resulting screenshot looks like: ## Conclusion Waiting for a page to load in order to get a clean screenshot is a lot more tricky than it first appears, depending on how that page is implemented. We've gone through all of the features that puppeteer provides that allow us to wait for a page to load: We can wait for certain events to fire, such as `load` and `domcontentloaded`. We can use puppeteer to wait for certain DOM elements to be hidden or visible. We also explored puppeteers methods that wait for the network to be idle for certain lengths of time before continuing. These can be useful for single page apps that are built with frameworks such as angular, react and vue. Finally, we wrote a custom function that waits for updates to the DOM to settle, which could be as close as we can come to making a generic page load function that works across all websites. --- # How to take website screenshots with Puppeteer > Learn how to capture website screenshots using headless chrome via the popular Puppeteer framework. Source: https://urlbox.com/website-screenshots-puppeteer Last updated: 2022-02-07 --- Looking to add a website screenshot feature to your product? Want to take full page web screenshots, screenshots of specific elements or screenshots from emulated devices? In this article we'll show you how you can use puppeteer to capture various kinds of screenshots from any url on the web. ## Why capture website screenshots? Here are just a few reasons why you might want to take website screenshots: - Capture screenshots of charts, dashboards and user-generated content to show on a user's profile page or send in an email: ![website screenshot of figma dashboard](/content/puppeteer/figma-dashboard-web-screenshots.png) - Capture screenshots on a schedule, hourly or daily for archiving or comparison: ![website screenshot of newscompare](/content/puppeteer/newscompare3.png) - At urlbox, we use website screenshots in our open-graph and twitter card metatags. When a link is shared to any page on urlbox.com, the link gets unfurled on slack, twitter or facebook, there will now be a nice screenshot of the page that is being shared. ![screenshot of slack unfurling url link](/content/puppeteer/slack-unfurl-urlbox.png) - Perhaps you just want to take a screenshot of a specific portion of a web page, such as a chart, the maps component on a google search results page, or of an individual tweet. ![screenshot of a chart](/content/puppeteer/chart-screenshot2.png) There are lots of use-cases for website screenshots, whichever use-case you have, capturing a screenshot of a website is made possible by using puppeteer. ## What kind of website screenshots can you capture? - #### Viewport screenshots This is where you set the viewport of the headless browser to a specific resolution and take a screenshot of the content that fills that viewport. This content is sometimes referred to as being 'above-the-fold'. - #### Full page screenshots Full page screenshots capture the entire webpage from the top of the page to the bottom of the footer. These are usually the most difficult kind of screenshot to capture accurately, due to how some sites are coded. - #### Screenshots of specific elements Element screenshots are useful for capturing a specific portion of a page, such as a specific tweet, the price of an item on an e-commerce page, or the comments section on an article. - #### Emulated device screenshots It's also possible to capture screenshots of a website by emulating a device. You can do this by altering the viewport, and setting a device specific user agent. - #### Geo-restricted website screenshots Sometimes a website will display different content to visitors in different countries. For example a news site based in the E.U. may not display certain articles to visitors from the U.S. To get around these scenarios, we can use a proxy server with puppeteer to make it appear to the website that we are based in the E.U. and allow us to access the geo restricted content. ## Prerequisites In order to get the most from the rest of this article, you should be comfortable with the following: - node.js, npm and JavaScript - Chrome devtools - CSS selectors, XPath expressions and DOM manipulation ## Introduction to puppeteer [Puppeteer](https://github.com/puppeteer/puppeteer) is a node.js library that allows you to automate headless browsers like [chromium](https://www.chromium.org/) and chrome. -> What is the difference between chrome and chromium? Chromium is the open-source project behind the proprietary Google Chrome browser. The main differences are that Google Chrome adds extra features such as the ability to login to a google account and sync browser settings.There are also differences in the support of proprietary codecs for various media formats, such as h264 video. This means that chromium sometimes will not load and display video's in your screenshots, whereas chrome would. Puppeteer is a nice abstraction on top of the [chrome devtools protocol](https://chromedevtools.github.io/devtools-protocol/). The devtools protocol could potentially be used directly, but the reason puppeteer is preferred is because it makes interfacing with the various methods and features of the devtools protocol much smoother. As an example, when you ask puppeteer to navigate to a website, it will call the devtool protocol's `Page.navigate` method described [here](https://chromedevtools.github.io/devtools-protocol/tot/Page/#method-navigate). All that said, in certain instances puppeteer gets in the way and it is necessary to use the devtools protocol directly in order to get around some of puppeteer's bugs. Let's try to capture a viewport screenshot of google.com... ## Using puppeteer to capture a website screenshot of google.com To get started using puppeteer, first we need to install it using npm: ```zsh npm install puppeteer ``` \~> As part of the install, puppeteer will download the latest compatible version of headless chromium. If you want to skip the download for some reason, you can pass the environment variable `PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true`. Next, we need to import the puppeteer module and write our first puppeteer script: ```js screenshot.js const puppeteer = require("puppeteer"); // using commonjs require syntax // import puppeteer from "puppeteer"; // if using es6/typescript import syntax puppeteer.launch().then(async (browser) => { const page = (await browser.pages())[0]; await page.goto("https://www.google.com"); await page.screenshot({ path: "google.png" }); await browser.close(); }); ``` This puppeteer script launches a new instance of headless chrome, navigates to the url "[https://google.com](https://google.com)" and captures a screenshot of the page. It saves the screenshot locally to a file named "google.png". \~> By default, puppeteer will always start chromium with a new, empty page (or tab) with the url `about:blank`. Instead of creating a new page we can just get a reference to this blank page by calling `browser.pages()` and getting the first item. To run the script, save the above code to a file named `screenshot.js` and run it using the command: ```zsh node screenshot.js ``` Here is the resulting website screenshot of google.com: ![website screenshot of google.com](/content/puppeteer/google.png) Oh dear - we were expecting to see the classic google.com homepage, with a simple search bar and the I'm Feeling Lucky button, but we seem to have taken a screenshot of a cookie popup instead! Also, it looks like our screenshot is quite small, by default the viewport on puppeteer is set to `800x600px` which defines the screenshot dimensions. Let's increase the viewport to something larger like `1280x1024` so we can see what's going on. Do this by calling `page.setViewport` and pass in our desired width and height: ```js {4} const puppeteer = require("puppeteer"); puppeteer.launch().then(async (browser) => { const page = (await browser.pages())[0]; await page.setViewport({ width: 1280, height: 1024 }); await page.goto("https://www.google.com"); await page.screenshot({ path: "google-1280x1024.png" }); await browser.close(); }); ``` Here's the resulting screenshot: ![website screenshot of google.com](/content/puppeteer/google-1280x1024.png) Now it's a bit clearer what's happening. The google.com site is showing us a cookie popup asking us to agree to their terms. That's annoying but part and parcel of the web in 2022! This is a common problem when using puppeteer to capture screenshots of websites. ### Removing the cookie popup from the screenshot In order to remove this popup, we have a few strategies - we can try to interact with the popup, like a regular human user would do, or we can forcefully hide the popup in order to reveal the actual content behind. \~> We can also get puppeteer to set a specific cookie, which google checks to see if a user that has previously agreed to the terms. Let's try to interact with the popup. We can do this by telling puppeteer to click the 'I agree' button for us. The easiest way is to use an XPath selector so that we can select the button element using it's actual text. The XPath expression `//button[contains(., 'I agree')]` should select all button elements with text that contains 'I agree'. We can test this in chrome devtools manually first, to ensure it is selecting the correct element. Start a new incognito session in your regular browser, browse to google.com and hopefully you should see the same cookie popup that we have screenshotted. If so, open the devtools console (option + command + J on a mac, control + shift + J on windows). Now in the chrome devtools console, you should be able to evaluate the expression using the code `$x("//button[contains(., 'I agree')]")`. ![devtools eval](/content/puppeteer/google-xpath-demo.png) Great, this is working, it is correctly selecting the button we want to click on. \~> Notice that the result from evaluating the XPath expression is an array, and the first item in the array is our button element. Now we can update our puppeteer script to run this same XPath expression and click on the button. ```js {6-9} const puppeteer = require("puppeteer"); puppeteer.launch().then(async (browser) => { const page = (await browser.pages())[0]; await page.setViewport({ width: 1280, height: 1024 }); await page.goto("https://www.google.com"); const xpathResult = await page.$x("//button[contains(., 'I agree')]"); // <- evaluate the xpath expression if (xpathResult.length > 0) { await xpathResult[0].click(); // <- clicking on the button } await page.screenshot({ path: "google-clicked.png" }); await browser.close(); }); ``` Here, we're using the [`page.$x(expression)`](https://github.com/puppeteer/puppeteer/blob/main/docs/api.md#pagexexpression) method to evaluate the XPath expression, and then using the `click()` method on the first element handle in the returned array to simulate clicking the button element. Run the script again, and here is the resulting screenshot: ![google-clicked](/content/puppeteer/google-clicked.png) That's better, the cookie popup has been clicked and we can finally see the search bar and the I'm Feeling Lucky button! ## Using puppeteer to capture full page website screenshots Now that we've taken a basic screenshot, let's take a screenshot of the entire page. Let's choose a different url to capture, as google.com is a bit too small for this. Something like apple.com would be better. Let's update our script to the following: ```js {8} const puppeteer = require("puppeteer"); puppeteer.launch().then(async (browser) => { const page = (await browser.pages())[0]; await page.setViewport({ width: 1280, height: 1024 }); await page.goto("https://apple.com"); await page.screenshot({ path: "apple-fullpage.png", fullPage: true, }); await browser.close(); }); ``` We simply pass `fullPage: true` in the options to the `page.screenshot` method. Let's see the resulting full page screenshot of apple.com: ![apple.com full page screenshot](/content/puppeteer/apple-fullpage.png) The issue with this full page screenshot is that there are some lazy loaded images at the bottom that have not loaded and so are blank in the screenshot. Let's fix that now. ### Scrolling to the bottom of the page to trigger lazy loaded images Lazy loaded image elements are designed to reduce the initial page load. They will only load when they enter or are about to enter the viewport. In order to get these images to load, we need to get puppeteer to scroll the page down, like a normal human user would do. We can use the `page.evaluate` method to simulate a human scrolling the page down. -> The `page.evaluate` method allows us to run arbitrary JavaScript code in the context of the website itself. It is equivalent to running code inside the devtools console. We could use this method for a whole variety of things - scraping particular information from the page like the title, clicking on certain elements or measuring the dimensions of the page. The fact that the code runs in the context of the page brings with it some problems, as it means we cannot be sure that any of our global objects such as `Array`, `Promise`, `JSON` and even `console` have not been tampered with by some code or plugin that the website has already loaded. This can be the source of some very strange and unexplained freezes when running puppeteer scripts on the wild web. The following method will scroll the page to the bottom, then back to the top: ```js const scrollPage = async (page) => { await page.evaluate(() => { return new Promise((resolve, reject) => { let interval; const reachedBottom = () => document.scrollingElement.scrollTop + window.innerHeight >= document.scrollingElement.scrollHeight; const scroll = async () => { document.scrollingElement.scrollTop += window.innerHeight / 2; if (reachedBottom()) { clearInterval(interval); document.scrollingElement.scrollTop = 0; resolve(); } }; interval = setInterval(scroll, 100); }); }); }; ``` The function above takes in the page object as an argument, then calls `evaluate` on it. The evaluate method takes an inner function which is evaluated inside the context of the website. If the inner function returns a promise, then `page.evaluate` will wait for the promise to resolve before returning. So, the first thing we do is return a new promise. Inside this promise, we create two functions, `reachedBottom` and `scroll`. `reachedBottom` is a function that checks if the page has scrolled to the bottom. `scroll` is a function that scrolls the page down by half the window height. It does this by setting the document's `scrollingElement`'s scrollTop property programatically. The `scroll` function is called on an interval of 100ms and if the `reachedBottom` function returns true, it clears the interval, sets the scrollTop back to 0 and resolves the promise. We await the `scrollPage` function from our script, after the page has loaded, but before we take the screenshot: ```js {6} const puppeteer = require("puppeteer"); puppeteer.launch().then(async (browser) => { const page = (await browser.pages())[0]; await page.setViewport({ width: 1280, height: 1024 }); await page.goto("https://apple.com"); await scrollPage(page); await page.screenshot({ path: "apple-fullpage-scrolled.png", fullPage: true, }); await browser.close(); }); ``` And here is the resulting screenshot now: ![screenshot of apple after scrolling the page](/content/puppeteer/apple-fullpage-scrolled.png) You can see that the images below the fold have now successfully loaded and the full page screenshot looks complete! ## Using puppeteer to take an element screenshot Now let's see how we can take an element screenshot using puppeteer. For this example we'll find a tweet, and try to grab a screenshot of just the tweet container rather than the whole page. Here's a random [example tweet](https://twitter.com/l__i_l__y/status/1487943103990403074) we can use. If we take a normal screenshot of this url we get the following image: ![viewport screenshot of tweet](/content/puppeteer/tweet-page.png) The screenshot above shows the tweet and all of the other elements that surround it on the page. But if we wanted to create a gallery of tweets, we'd want to focus on the tweet content and only capture a screenshot of this portion of the page. In order for puppeteer to capture an element screenshot, it needs to know how to find the specific element in the DOM. We can use CSS selectors or XPath expressions to find the element. In this example we'll use CSS selectors to target the element. ### Finding the element to screenshot Open a new incognito browser window, navigate to the tweet url and open the devtools. Once inside devtools, click on the 'elements' tab and hover over the elements in the DOM tree until you find the most appropriate element that contains the whole tweet and nothing but the whole tweet: ![selecting tweet element](/content/puppeteer/selecting-tweet-element.png) From here, you can right click on the element and choose the copy > copy selector option. ![copy selector](/content/puppeteer/copy-selector.png) This will copy the selector of the element to your clipboard. For me, the selector was: ``` #react-root > div > div > div.css-1dbjc4n.r-18u37iz.r-13qz1uu.r-417010 > main > div > div > div > div.css-1dbjc4n.r-14lw9ot.r-jxzhtn.r-1ljd8xs.r-13l2t4g.r-1phboty.r-1jgb5lz.r-11wrixw.r-61z16t.r-1ye8kvj.r-13qz1uu.r-184en5c > div > section > div > div > div:nth-child(1) > div > div:nth-child(1) > article ``` Which is kind of gnarly. It's also really brittle - if twitter updates it's DOM structure, it's likely to break this selector. If we just use our own eyes we can observe that there's only two `
` elements on the page, and running `document.querySelector('article')` will return the first one, which happens to be the element we'd like to screenshot. Therefore, the CSS selector we can use to target the tweet element is simply `article`. Now let's modify our first script to take a screenshot of the tweet element: ```js {6,7} const puppeteer = require("puppeteer"); puppeteer.launch({ headless: false }).then(async (browser) => { const page = (await browser.pages())[0]; await page.setViewport({ width: 1280, height: 1024 }); await page.goto("https://twitter.com/l__i_l__y/status/1487943103990403074"); const tweetElem = await page.$("article"); await tweetElem.screenshot({ path: "tweet-selector.png" }); await browser.close(); }); ``` -> Note I'm disabling `headless` mode here by passing `{ headless: false }{:js}` to the `launch` function. When you run puppeteer in headful mode, it will show the browser window and you can visualise what's happening. This makes debugging things a little easier :) Here we're using the `page.$` method to get a handle to the element we want to screenshot. This is equivalent to running `document.querySelector(selector)` in the devtools console. We're then calling the `screenshot` method on the element handle rather than on the page object, in order to get a screenshot of just the element. Here's the resulting screenshot: ![screenshot of a tweet element](/content/puppeteer/tweet-selector-broken.png) Hmm, that is not the element screenshot we wanted! Instead of taking a screenshot of the tweet element, we appear to have taken a tweet-sized screenshot but with the wrong offset, as demonstrated below: ![actual vs expected screenshot](/content/puppeteer/tweet-expected-actual.png) In order to figure out what's going on, we need to delve right into the puppeteer code for element screenshots. [This function](https://github.com/puppeteer/puppeteer/blob/v13.1.3/src/common/JSHandle.ts#L925-L981) in the puppeteer source code is responsible for taking an element screenshot. It: 1. scrolls the element into view (if needed) using [`element.scrollIntoView()`](https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView) 2. gets the `boundingBox` of the element using [`DOM.getBoxModel()`](https://chromedevtools.github.io/devtools-protocol/tot/DOM/#method-getBoxModel) from chrome devtools protocol. 3. offsets the `boundingBox` by adding `pageX` and `pageY` values from the `cssLayoutViewport` object returned from `Page.getLayoutMetrics`, and returns the offsetted `boundingBox`. 4. calls the `Page.screenshot` method, passing the `boundingBox` into the `clip` property, which clips the screenshot to the dimensions specified by the offset bounding box. Unfortunately, step 3 above is currently a bug in puppeteer, which has been reported a [few](https://github.com/puppeteer/puppeteer/issues/7533) [times](https://github.com/puppeteer/puppeteer/issues/7514) already. The `pageX` and `pageY` values returned from `cssLayoutViewport` are sometimes incorrect in headless mode, and should not be added as offsets to the clip object. ### Working around puppeteer's element screenshot bug To fix the bug with puppeteers default element screenshot implementation, we can write our own method to find the element, get the correct co-ordinates and dimensions for the element, and pass that as the `clip` object to the `page#screenshot` method. The method we'll write is called `getElementDimensions`: ```js const getElementDimensions = async (page, selector) => { return page.evaluate(async (innerSelector) => { let elem = document.querySelector(innerSelector); if (!elem) { throw new Error("element not found"); } elem.scrollIntoViewIfNeeded(); let boundingBox = elem.getBoundingClientRect(); return { width: Math.round(boundingBox.width), height: Math.round(boundingBox.height), x: Math.round(boundingBox.x), y: Math.round(boundingBox.y), }; }, selector); }; ``` This method takes in the page object, and a CSS selector. It then calls the `evaluate` method on the Page as we've seen before. But this time we want to pass our selector string as a parameter to our evaluate function, so that we can use it inside the inner function. -> How do we pass parameters to puppeteers evaluate function? The way we do this is to pass in the argument as the *second* parameter to evaluate (after our function argument). This becomes the *first* argument in our inner function. In the example above I've explicitly renamed the `selector` argument to `innerSelector` to make it clear that we're now accessing the variable inside a different context. The `getElementDimensions` function: 1. attempts to find the element in the DOM using [`document.querySelector(selector)`](https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector) with the passed-in selector argument 2. throws an error if the element is not found 3. scrolls the element into view using [`element.scrollIntoViewIfNeeded()`](https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoViewIfNeeded) 4. gets the `boundingBox` of the element using [`element.getBoundingClientRect()`](https://developer.mozilla.org/en-US/docs/Web/API/Element/getBoundingClientRect) 5. returns an object with the element dimensions with keys corresponding to the `clip` object that puppeteer's screenshot function expects -> Why do we need to round the dimensions? The `clip` object that we are passing to `Page.screenshot` expects whole numbers, whereas the values returned by `element.getBoundingClientRect` are decimal values. To convert them into whole numbers, we use `Math.round`, which should return the closest whole number Now let's update our original script to call our new `getElementDimensions` function: ```js {6,9} const puppeteer = require("puppeteer"); puppeteer.launch({ headless: true }).then(async (browser) => { const page = (await browser.pages())[0]; await page.setViewport({ width: 1280, height: 1024 }); await page.goto("https://twitter.com/l__i_l__y/status/1487943103990403074"); let elementClip = await getElementDimensions(page, "article"); await page.screenshot({ path: "tweet-selector.png", clip: elementClip, }); await browser.close(); }); ``` Run the updated script, and then the output should be: ![fixed element screenshot of tweet](/content/puppeteer/tweet-selector.png) Ok, finally.. that looks better :) ## Conclusion In this article we attempted to take three different types of screenshots, on three of the most prominent websites on the internet: 1. A viewport screenshot of google.com 2. A full-page screenshot of apple.com 3. An element screenshot of a tweet on twitter.com **In each case, we ran into issues that had to be worked around:** 1. Google showed us a cookie banner which we had to manually target and remove. 2. Apple's use of lazy-loaded images meant that our initial full page screenshot had empty images, so we had to write some code to scroll the page to the bottom before taking the screenshot. 3. The initial tweet screenshot was off, due to a bug in puppeteers element screenshot algorithm. So we had to write some code to get the correct co-ordinates of the tweet element. These kind of issues can make it time consuming to maintain your own screenshot service. They are just the tip of the iceberg when trying to screenshot the wild web.

It's a fairly common requirement for all sorts of sites, but it can be complex to get started. In this article, we're going to explore the main ways of doing it. Table of Contents ## The options There are essentially two main methods of generating screenshots and displaying them on your WordPress website: - You can implement them yourself with some code - You can use a plugin We're going to look at both methods. We'll start with the code option: ## Implement screenshots yourself with code This is the more involved of the methods. You'll need: - A WordPress website which you own (we'll need to use an administrator account) - A text editor, like TextEdit on macOS or Notepad on Windows, or a code editor. My preference is for [VS Code](https://code.visualstudio.com/) \~> Note: Many WordPress tutorials which show you some code to use on your site will tell you to put that code into your theme's `functions.php` file. This is not a good idea, as that file is specific to the theme you're using. Firstly, it can get overridden by a theme update - which will destroy your work. Secondly, if you decide to use a different theme on your site, that code will then be ignored by WordPress (because that theme is no longer active). What we're going to do is create our own simple plugin for this task. That way, it will be independent of our site theme - and we can enable or disable it as necessary. We're going to use this plugin to implement [shortcodes](https://developer.wordpress.org/plugins/shortcodes/) for our site, which will allow us to generate screenshots in any page or post by adding a shortcode in the WordPress editor. This is a nice way of achieving our goal, as we only need to write the code once - we can change the screenshotted site address, etc. in the editor. \~> We'll be using the [mshots](https://github.com/Automattic/mShots) API service to generate our screenshots. This is a basic service provided by Automattic, the company behind WordPress.com - it's free for limited, non-commercial use. ### Setting things up Let's get started! We need to create a folder somewhere on our computer (the desktop is fine for now) for our plugin's files (this plugin will only have one file). The name should reflect what the plugin does, and words should be separated by dashes. I've called mine `my-screenshots-plugin`. Inside that folder, we need to create the actual plugin file - this needs to have a `.php` extension (and again, words separated by dashes) - I've kept our naming convention and called mine `my-screenshots-plugin.php`. ### Adding code to our plugin Let's open this file in our editor and paste in the following code: ```php 'http://s.wordpress.com/mshots/v1/', "url" => '', "alt_text" => 'a screenshot', // Default alt-text "width" => '', // Default width, if set "height" => '' // Default height, if set ), $atts)); // Create an HTML string from the parameters $screenshot = '' . $alt_text . ''; // Return the assembled HTML to the page or post return $screenshot; } ``` What we're doing here is: - Preventing browsers from accessing this file directly (which is a security risk) - Declaring our function, `generate_screenshot` - Giving it the parameters we want it to use: - The mshots service API 'endpoint' it needs to talk to, in order to generate the screenshot - Some placeholders/default values for the HTML it will produce, which can be overridden with our shortcode - Stitching everything together into an HTML `` element (an image) for it to display in our page or post, in place of the shortcode Now let's *register* our shortcode function against the shortcode, so that the function runs when we use our shortcode in a page or post: ```php // Register the shortcode add_shortcode('screenshot', 'generate_screenshot'); ``` And finally, we need to close our PHP file: ```php ?> ``` That should be everything we need for our very simple shortcode plugin. Here's the whole thing: ```php 'http://s.wordpress.com/mshots/v1/', "url" => '', "alt_text" => 'a screenshot', // Default alt-text "width" => '', // Default width, if set "height" => '' // Default height, if set ), $atts)); // Create an HTML string from the parameters $screenshot = '' . $alt_text . ''; // Return the assembled HTML to the page or post return $screenshot; } // Register the shortcode add_shortcode('screenshot', 'generate_screenshot'); ?> ``` \~> Important: This is a very simple plugin implementation, and doesn't take into account any security requirements other than the very basic check under the plugin header. Theme and plugin security is a complex subject, and caution should always be used when adding PHP code to your WordPress site. ### Adding the plugin to our site Let's make sure that we have saved our PHP file. We're now going to upload it to our WordPress site. We could do this fia FTP, assuming we have access to the web server's filesystem. To keep things simple here, though, we're going to upload it via the WordPress admin area. In order for WordPress to accept the plugin, it needs to be compressed into a 'zip' file. This is simple - we just right-click or control-click the plugin folder and select 'Compress'. This varies slightly across operating systems, but the idea is the same. This will produce a zipped folder - in our case, `my-screenshots-plugin.zip`: ![Zipping up a file](/content/wordpress/zip-file.png) Now we can go to our WordPress admin area, and then to the Plugins page. We're going to click 'Add New' and then 'Upload Plugin', then select our zip file and upload it. Now, if we go back to the Plugins page, we should see our plugin there: ![Viewing our plugin in the WordPress admin](/content/wordpress/plugin-page-1.png) All we need to do is click 'Activate', and it's ready to use! ### Using the shortcode Now that we have implemented the `mshots` API in a plugin, and registered a shortcode to use the service, we can start adding screenshots to our site. let's create a new post or page (you could also edit an existing one, of course), and insert a [shortcode block](https://wordpress.com/support/wordpress-editor/blocks/shortcode-block/) - I'm assuming here that you're using a modern version of WordPress with the block editor. Inside that block, we can now add a shortcode. Here I'm adding the shortcode: `[screenshot url='bbc.com']` ![Inserting a shortcode](/content/wordpress/shortcode-1.png) And here's what our page looks like when we visit it: ![Viewing the results](/content/wordpress/render-1.png) Looking good! Let's add another screenshot. Let's stick to the 'news' theme - this time, I'll take a screenshot of the Guardian site with: `[screenshot url='theguardian.com']` ![Inserting another shortcode](/content/wordpress/shortcode-2.png) Let's have a look at our page now: ![Viewing the results](/content/wordpress/render-2.png) Fantastic - we can add as many screenshots as we like to a post or page. We can even arrange them in different ways by putting the Shortcode blocks inside other blocks - perhaps we want a 2 column layout with 2 screenshots side-by side. Let's add: `[screenshot url='gizmodo.com']` and `[screenshot url='apple.com']` ![Adding more shortcodes in a columns block](/content/wordpress/shortcode-3.png) Which looks like this: ![Adding more shortcodes in a columns block](/content/wordpress/render-3.png) \~> The image alignment of the first screenshots now looks a little off, because we haven't wrapped them in any other blocks - and our simple plugin doesn't handle any HTML 'wrapping' for us. This suffices for our example, though. This is great - we can add a screenshot of any site, wherever we like. You've probably already spotted an issue here, though. Lots of sites have ads, cookie banners, etc. - and our screenshots show them. In many cases, there's not much actual content left between the various bits of cruft on a site. That's not ideal - and there's not really anything we can do about that. The `mshots` API loads a page, then takes a screenshot. Whatever appears on that page ends up in the screenshot. When we visit pages in our browser, we dismiss cookie notices - and many of us use ad blockers to make browsing less frustrating. But we can't do that when we're using a basic service like `mshots`. So how can we deal with this issue? Well - it turns out that programmatically dismissing cookie consent notices, removing ads, etc. is technically complex. Thankfully, Urlbox has put a lot of time and effort into solving these issues (and many more). Let's move on to the second method of adding screenshots to our WordPress site (this part of the article will be a lot shorter!): ## Use a professional screenshot service Urlbox does a lot of 'heavy lifting' for you when it comes to taking screenshots: - It gets rid of ads, cookie notices, and other pop-ups - It lets you take full-page screenshots - It makes sure that 'lazy loaded' images have loaded before taking the screenshot - It lets you specify the browser size and user agent, for truly responsive screenshots - It supports web fonts and emojis correctly It has a truly comprehensive API, with options for pretty much anything you can imagine. So how do we implement Urlbox in our WordPress site ...? You've guessed it - there's a plugin for that! It will allow us to use Urlbox in exactly the same way - by writing simple shortcodes. Let's head back to our WordPress admin area, go to the Plugins page, and hit 'Add New'. There we can search for Urlbox: ![Installing the Urlbox plugin](/content/wordpress/install-plugin.png) Let's install and activate it. It should show up next to our own plugin: ![Viewing the Urlbox plugin in the WordPress admin](/content/wordpress/plugin-page-2.png) We can visit the settings page from the link under its title, or from Settings > Urlbox. As you can see, there are quite a few options: ![Viewing the Urlbox options in the WordPress admin](/content/wordpress/urlbox-settings-1.png) In fact, while some frequently used options are provided here for convenience, any of the options on the [API Options page](https://urlbox.com/docs/options.md) can be used in our Urlbox shortcodes. \~> Note: The options above are defaults - only use these if you want them to apply to every screenshot on your site. We can set options for each shortcode individually, which is how I suggest you use them. Before we can use the plugin, we need to enter our API key and secret. If you don't already have a Urlbox account, head to the [Urlbox homepage](https://urlbox.com/.md) and sign up for a free trial. You don't need to put in any card details. Urlbox has plans for every type of user, starting at $19 per month for 2,000 screenshots. You'll find your API key and secret on your [dashboard](https://urlbox.com/dashboard.md) - enter them in the fields at the top of the plugin settings page (remember to hit 'Save Settings' at the bottom): ![Viewing the Urlbox options in the WordPress admin](/content/wordpress/urlbox-settings-2.png) Now, let's head back to our editor and swap out our `screenshot` shortcode for our new `urlbox` one. I've added `block_ads=true` and `hide_cookie_banners=true` to the Guardian site, and `block_ads=true` to the Gizmodo site: ![Changing the shortcodes](/content/wordpress/shortcode-4.png) \~> Note: With the Urlbox plugin, we can also leave off the single quotes around the options. This is what our page looks like now: ![Viewing results with the updated shortcodes](/content/wordpress/render-4.png) That's better - no more ads or cookie banners, and the images all line up nicely with no work from us. ## Conclusion As with most things, there's a hard way and an easy way. When it comes to screenshots, Urlbox does the heavy lifting - so you don't have to.
