Frequently asked questions
Are my files uploaded?
No. All processing runs in your browser via Canvas API.
Can I combine chat screenshots?
Yes. Vertical mode + gap 0px gives a seamless single image. Stitching messenger captures is a core use case.
What if my photos have different sizes?
Horizontal: scaled to first photo's height. Vertical: scaled to first photo's width. Grid: contain-fit to cell size.
Can I reorder photos?
Yes. Use ↑↓ in the file list. Preview updates immediately.
How many photos can I combine?
No hard limit. Result canvas must stay under browser limit (~16k×16k). Generally 20-30 works fine.
