About

ScrollStitch Screenshot Merge

Features
Read full description

Twelve screenshots to show one conversation. A receipt that won't fit. A thread you can't share without cropping. Record your screen while you scroll, hand the video to ScrollStitch, and get back one tall image with nothing missing. HOW IT WORKS 1. Record your screen while scrolling steadily through the content 2. Open ScrollStitch and pick that recording 3. Save the result to Photos, or export it as a PDF BUILT TO GET THE SEAM RIGHT Most stitching tools guess where two frames meet. ScrollStitch measures it. Every frame is compared against the one before it to find the exact overlap, so the join lands where the content genuinely lines up — not a few pixels off. • Sticky headers and floating toolbars are detected and removed, so they don't repeat down the length of the image • Duplicate frames from pauses are dropped automatically • Dark and low-contrast screens are handled rather than given up on • If a scroll jumped too fast to match, the gap is marked — never silently invented WHAT YOU GET • One long image, saved straight to Photos • A PDF for sharing or filing • Trim the top and bottom before you save • Put your phone down while it works — a notification tells you when it's ready GOOD FOR Chat threads, long receipts, articles, terms you need on file, order confirmations, code reviews — anything taller than your screen. SUBSCRIPTION ScrollStitch is a subscription app. The weekly plan starts with a 3-day free trial; an annual plan is also available.
