How do I combine screenshots without duplicated rows?

Leave the automatic overlap detection on. It compares the bottom of one screenshot with the top of the next and removes the matching rows, so you get one long image instead of a stack with repeated blocks.

Are my screenshots uploaded anywhere?

No. The stitching runs in your browser and the images never leave your device — you can even go offline once the page has loaded.

Combine Screenshots Into One Long Image

Take your screenshots top to bottom, drop them here in order, and get one continuous image. The overlapping part of every pair is measured pixel by pixel and de-duplicated, so a three-shot capture does not repeat the same rows twice.

Pick the vertical layout, leave the gap at zero, and widen the overlap search range if your screenshots share less than a fifth of their height. When a pair cannot be matched, the page says so and you can nudge the offset by hand.
