FAQ

What if my photos are different sizes?

Use Match sizes. "Same width" scales everything to one width (best for stitching screenshots into a long image), "Same height" is best for a horizontal strip, and "Crop to identical cells" centre-crops each photo into a square-ish cell for a tidy grid.

Is there a size limit?

Browsers cap canvas dimensions, so extremely tall stitches can fail. The Max output side setting scales the finished collage down to a safe size — lower it if a very long stitch comes out blank.

Do the images get uploaded?

No. Decoding, layout and encoding all happen in this tab; nothing is sent anywhere.
