GoFullPage (Full Page Screen Capture) is a Chrome extension, also usable in other Chromium browsers, that captures an entire scrollable page in one shot with no manual scrolling or stitching.
It renders and captures everything below the fold automatically, including content that loads as you scroll, then exports as PNG, JPEG, or PDF with a built-in editor for cropping and annotation - a full-page capture devtools can only approximate with its own screenshot command and none of the editing.
Use it to archive a competitor's full landing page for a swipe file, hand a client a complete visual record of their live site before a redesign, or grab a full-length reference of a long-scroll page you're rebuilding.
To capture everything on a page it needs to read that page's content, so it carries the same broad site-access permission most capture tools require.
Capture a full-page screenshot of any website, no scrolling and stitching required.
