Collage Maker
Arranges photos into a grid or mosaic layout with adjustable gutters, corners and background.
Photos into a grid, with the cell shape and the fit as the two decisions that matter. “Fill the cell” crops the wider photos to make every cell full; “fit inside” keeps every photo whole and leaves background showing. There is no third answer that does both.

How to use it
Drop the photos in the order you want them
The list is the layout order, and it is reorderable — not alphabetical, which would put photo 10 between 1 and 2.
Set the columns and the cell size
A square cell with “fill” is the social grid; a taller cell with “fit inside” suits mixed portrait and landscape.
Add gap, padding and a background
The gap and the outer padding are drawn in the background colour, so a white background and a generous gap gives the album-page look.
Common questions
Why is the last row not stretched to fill?
Because stretching it would change the size of exactly those photos and no others. Five photos in three columns would become three normal cells and two enormous ones — and with “fill”, a different crop on two of the five.
Can I put the photos in different-sized cells?
Not here — this is a uniform grid. A mosaic with a feature cell is a layout decision rather than a setting, and it is faster to make in a design tool than to describe with sliders.
The output file is very large.
Nine 600px cells is a 1900px canvas of PNG. That is deliberate — the collage is composed at full quality — so run it through the resizer or the JPEG converter afterwards if it is going somewhere with a size limit.
