Frequently asked questions
Are my photos uploaded?
No. The collage is drawn on a canvas in your browser, so your photos stay on your device.
How do I stitch screenshots into one long image?
Choose Long image. Every picture is scaled to a Common width (Smallest, Largest or a custom pixel value) and stacked top to bottom with your spacing. Side by side does the same horizontally with a common height.
Why is one of my photos marked Not used?
Fixed templates have a set number of cells; 2×2, for example, holds four photos. Extra images are dimmed and left out. Pick Auto, which fits any number of photos, or Custom with your own rows and columns (up to 10 × 10).
Why are the edges of my photos cut off?
Fill (crop) fills each cell and trims the overflow; drag the photo in the preview to choose the visible part. Whole image shows the complete photo inside its cell, with background around it.
Is there a size limit?
In Grid you can set the output width up to 12,000 px. Collages beyond the browser's canvas limit (30,000 px per side or about 120 megapixels) are scaled down automatically, and a note tells you when that happens.
Can the background be transparent?
Yes. Turn on Transparent background and the format switches from JPG to PNG. WebP keeps transparency too.
