Frequently Asked Questions
What if I have fewer images than slots?
Empty slots are filled with a light gray placeholder. You can still generate and download the collage with empty slots.
Are images cropped?
Yes — images are center-cropped to fill the square cell. No stretching occurs. The crop follows a cover-fit algorithm.
What output format is used?
JPEG at 90% quality. The Canvas API produces the output — no third-party image library is needed.
