## Description

Turn 2–10 overlapping screenshots into one continuous PNG.<br><br>ScrollJoin is a focused screenshot stitcher for long chats, articles, receipts, instructions, social posts, notes, and other content that does not fit on one screen. Select same-width, upright screenshots in reading order, then review the result before exporting it.<br><br>AUTOMATIC OVERLAP MATCHING<br><br>ScrollJoin compares neighboring screenshots using color-aware overlap analysis. When it finds a reliable shared area, it removes the repeated content and creates a clean join.<br><br>SAFE WHEN A MATCH IS UNCERTAIN<br><br>An uncertain match never causes content to be silently removed. ScrollJoin keeps the complete screenshots in a safe unresolved stack and marks the join for review.<br><br>MANUAL LIVE JOIN EDITOR<br><br>Open any join to inspect both screenshots together. Adjust the join manually while the combined result updates live, then confirm it when the transition looks right.<br><br>ORIGINAL-SIZE PNG OUTPUT<br><br>Export one RGBA PNG at the original screenshot width. ScrollJoin does not scale the screenshots to make them fit.<br><br>PRIVATE BY DESIGN<br><br>• Works offline<br>• Processes screenshots on your device<br>• No account<br>• No ads<br>• No analytics<br>• No permission to browse your full photo library<br>• Access only to the images you choose<br><br>HOW TO USE SCROLLJOIN<br><br>1. Choose 2–10 same-width, upright screenshots in reading order.<br>2. Let ScrollJoin analyze the overlap between each neighboring pair.<br>3. Review any unresolved or uncertain join.<br>4. Fine-tune a join in the live manual editor when needed.<br>5. Export the result as one original-size PNG.<br><br>FOR BEST RESULTS<br><br>Leave some repeated content between neighboring screenshots. Use screenshots with the same width and keep them upright. Moving content, animations, different zoom levels, or screenshots without a shared area may require manual adjustment.<br><br>ScrollJoin does one job: it helps you stitch screenshots into a long image while keeping every uncertain join under your control.
