SeamShot – Full Page Screenshot & Auto Capture

Seam-verified full-page screenshots. Overlapping regions are pixel-checked before stitching.

SeamShot captures the entire page — not just what fits on your screen — and verifies every stitch point before handing you the image, so you never end up with a duplicated header, a missing line, or a torn image where two scrolls met. HOW IT WORKS Most full-page screenshot tools scroll and stitch blind, hoping the seams line up. SeamShot checks each overlapping region pixel-by-pixel as it captures. If a seam doesn't match, it retries automatically before moving on — so what you get is a full, continuous page image you can actually trust. FEATURES Full-page capture • One click captures the entire page, including content that only loads as you scroll • Save as PNG, copy straight to your clipboard, or export a PDF with selectable text • Works on pages with scrollable inner containers (not just the whole document), including feeds and embedded iframes Compare to a previous capture • Automatically keeps your last capture of a page so you can see what changed • Word-level text diff highlights additions and removals in context • Side-by-side before/after view with image-change detection Watch a page for changes • Point SeamShot at a whole page or a single element and it checks back on a schedule you set • Runs in the background — no need to keep the tab, or even the browser window, open • Get a desktop notification the moment something changes, with a running history log of what changed and when • Auto-pauses after repeated failures instead of silently dying Tamper-evident by design • Every capture is stamped with a SHA-256 hash, so you can prove later that an image hasn't been altered PRIVACY SeamShot captures and processes pages entirely on your device. Nothing is uploaded to any server — captures, comparisons, and watch history all stay in your browser's local storage. Built for anyone who needs a screenshot that's actually the whole page: researchers archiving web content, support teams documenting bugs, and anyone who's been burned by a "full page" capture that wasn't.
