Guides
Step-by-step Urlbox guides for bulk screenshots, proxies, avoiding blocks, logged-in pages, local URLs, saving to S3, thumbnails and side renders.
These guides walk through real-world rendering tasks from start to finish, with the exact options to set and working examples. If something has gone wrong with a render, start with Common Problems. For a single option, look it up in Render Options.
Capturing the page you want
Avoiding being blocked
Detect block pages and CAPTCHAs, retry blocked renders automatically, and use stealth and proxies to capture the real content.
Using proxies
Route renders through your own proxy, choose a location, and fix ERR_TUNNEL_CONNECTION_FAILED.
Setting the user agent
Override the user agent string per render.
Rendering behind a login
Screenshot pages that need you to be signed in, using session cookies or auth headers.
Rendering local URLs
Render sites on localhost or a private network by exposing them through a tunnel.
Rendering at scale
Taking screenshots of all pages on a website
Pull every URL from a sitemap and screenshot each page.
Sync vs async
When to wait for a render and when to get the result by webhook or polling.
Saving to S3
Save renders straight to your own S3-compatible bucket.
