Skip to main content
The screenshot tool captures a fully javascript-rendered screenshot of a given webpage using Chromium, without writing any automation code. Call POST /v1/tools/screenshot with the target url, and the API returns the captured image as a PNG. The tool can run standalone or against an existing browser session — pass an optional sessionId query parameter to execute it on a running session (for example, to capture a page behind authentication).
PDF URLs are not supported by the screenshot tool.

​
Request options

  • url: The URL of the webpage to capture.
  • width / height: Browser viewport dimensions in pixels.
  • image_quality: Quality of the output image, on the range 1-100. 100 will not perform any compression.
  • wait: Duration in milliseconds to wait after the page has loaded, mainly used for sites with JS animations.
  • scroll_all_content: If true, scrolls the page and captures all visible content.
  • capture_full_height: If true, captures the entire height of the page, ignoring the viewport height.
  • s3_target_address: Presigned S3 url target to upload the image to.
See the full API reference for details.
