About
Seamreel turns a messy pile of overlapping screenshots into one clean, seamless vertical image — the way you'd actually want to share a long Slack thread, a scrolling web article, or a stack of code review comments.
Drop your screenshots in any order. Seamreel scans each pair for pixel-level overlap, automatically sorts them into the right sequence, trims the duplicate bands, and stitches them into a single tall PNG — no manual cropping, no layer juggling, no guesswork.
WHAT MAKES IT DIFFERENT
- Auto-sort by overlap — drop the pile in any order and Seamreel figures out the sequence
- Live film-strip preview — watch the merged strip build in real time as each seam locks in
- Adjustable seam sensitivity — Fast, Balanced, or Precise matching for tricky captures
- Full stitch history — every export is saved so you can revisit, re-export, or delete it later
- One click to export — a single tall PNG, ready to share
Built entirely offline. No account, no cloud upload, no data collection — every screenshot and every stitch stays on your Mac.
Included: up to 10 lifetime stitches. Unlock Pro for unlimited stitching — a single one-time purchase, no subscription.
