Capture the whole story.
Zero seams.

Every seam is pixel-checked before it's stitched in — so your full-page screenshot looks exactly like the page did.

⚠️

You've seen this before: a screenshot with a header pasted in twice, or a sentence sliced clean in half.

Every "full page" tool scrolls, snaps, and hopes the pieces line up — and half the time they don't. SeamShot checks every overlap pixel-by-pixel and re-shoots it automatically if it's off, before it ever reaches your image. That's the Overlap Logic behind SeamShot.

Core Technology

Pixel-Perfect Overlap Stitching

SeamShot captures overlapping slices and cross-checks every pixel where they meet. If two slices don't line up, it recaptures automatically — so the seam disappears instead of showing up in your screenshot.

  • Sub-pixel alignment correction
  • Dynamic scroll delay handling
  • Sticky element auto-detection

The background watcher.

Register a URL to periodically auto-recapture and get notified when it changes. Track a price, a job listing, or any page you care about — even with the tab closed.

Compare Reports

Capture the same page at different times. We generate a visual diff highlighting changed regions and a text diff for content changes.

SHA-256 Hash Stamp

For legal and QA professionals. Every screenshot is stamped with a tamper-proof hash, timestamp, and URL metadata.

Change History Log

Every change a watch detects gets logged with a timestamp and a plain-text summary — a running record of when a page actually changed, not just a "last checked" time.

Text-Selectable PDF

Not just an image. Export your full-page capture as a vector PDF where every word remains searchable and selectable.

Why SeamShot

One extension, five things a plain screenshot tool doesn't do.
