LONG IMAGE STITCHING / DUOCANVAS GUIDE

One long image. A complete story.

Stitch photos or overlapping screenshots into one long image on your iPhone. Review joins, crop individual images, and cover private details before sharing.

2–20 photos or screenshotsAutomatic & manual joinsJPEG or PNG export

  1. Select images in order

    Open Long Image from Home and choose 2–20 photos or screenshots in the order you want them to appear.

  2. Stack or stitch

    Stack images vertically, or check joins between overlapping screenshots. DuoCanvas removes repeated content when it finds a confident match; review uncertain joins and adjust them manually.

  3. Refine and cover details

    Reorder or crop individual images, adjust spacing and background color, and use Redact to cover private details with solid black or white. Your source files remain unchanged.

  4. Review and export

    Check the overview and any joins that still need attention. Export the finished long image as JPEG or PNG, then save it to Photos or share the exported file.
