The JavaScript
Website Screenshot API

Urlbox is the website screenshot API for JavaScript that makes fast, accurate screenshots. Finally, a screenshot API you can depend on without writing your own microservice.

We’re profitable, privately owned, and in this for the long haul. Since 2012 we’ve generated hundreds of millions of screenshots for companies of all sizes.

Using Urlbox, we've scaled our volume to over 5 times what we were. We’re confident that Urlbox will continue to produce great results as we grow.

Urlbox's support of emojis was a big signal that it could replace our own service. It was a simple replacement - a real success story for us.

Check out our NPM package and GitHub repo

// 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: '',
    thumb_width: 600,
    format: 'jpg',
    quality: 80

const imgUrl = urlbox.generateRenderLink(options);

// Now set it as the src in an img tag to render the screenshot
<img src={imgUrl} />

If you're happy maintaining more JavaScript, DIY screenshot APIs are easier to get started with than they used to be.

Urlbox has been through a few iterations over the years. We started off in 2012 using Node.js v0.6. Today it is still mostly written in JavaScript and increasingly TypeScript.

For the rendering engine, we started off using PhantomJS, then moved through various projects - webkit2png, QtWebkit and Electron before settling down with headless Chrome/Chromium (via Puppeteer).

There are loads of website screenshot APIs.
Urlbox focused on being the best since 2012.

Urlbox's screenshots are considered the most accurate and high quality of any screenshot service.

The Urlbox team sweat the small stuff, ensuring that fonts and emoji's render correctly. We cringe with you at full page website screenshots with repeating scrollbars and ugly horizontal seams. Other APIs struggle to handle newer CSS features such as Flexbox, Grid and slower loading WebGL pages.

So what sets Urlbox apart from other APIs?

Here are six ways Urlbox outperforms other screen capture APIs.

A better way to take screenshots.

Retina Images

Render quality high-dpi images that look great on retina screens.

Block Popups

Block annoying pop-ups from getting in the way of your screenshots.

Click Accept

Dismiss cookie banners getting in the way of your screenshots.

Block Ads

Hide ads from taking all the attention in your screenshots.

Bypass Captchas

Automatically attempt to solve and bypass any captchas that are shown.

Bring Your Own Proxy

Use a proxy server to get around sites blocking your screenshots.

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.

Other APIs look and feel dated.

You'll find Urlbox's dashboard and documentation fresh and regularly updated.

Choose your render mode

With Urlbox you can preview all available API options and check API usage on our modern dashboard.

With other APIs you'll feel like you've stepped into a computer history museum.

Screenshot API render mode

More output formats

With Urlbox you can render screenshots as PNG, JPEG, WEBP, AVIF, SVG, PDF and even HTML.

With other APIs you can render in only one or two formats.

Output format

Delay settings

With Urlbox you can ensure a screenshot is only taken when a certain element is either in the DOM, or has left the DOM. Very useful if a web page has lazy loading and you want to make sure spinners are gone before generating a screenshot.

With other APIs the burden is on the page you're screenshotting which is often out of your control.

Delayed screenshot API

Request options

With Urlbox you have all the power you need to set headers, proxies and user agents. You can even fail an API request if certain elements are present or not-present in the DOM. That means they won't count against your monthly quota!

With other APIs you pay for just a handful of options... regardless of whether or not they actually work.

Output format

Exceptional support

Sadly, you'll hear many complaints about the level of support from other screenshot APIs.

You can see for yourself on various forums such as Twitter. Priority support really does mean priority support at Urlbox.

With Urlbox you'll rarely have to wait for a whole business day - usually we'll get back to you within the hour!

It's so evident that Urlbox really cares and pays attention. It's rare that I need customer support but, when I do, I know one of the team will get right back to me.

I love the support that Urlbox provides. Normally when I have a new feature request like WebP images or blocking cookie pop-ups, I email support and get a response saying it's already possible - within minutes.
