Photo collage maker: combine photos into one
A few photos you want to post as one — a 2×2 to sum up a day, a side-by-side before/after, a 3×3 photo wall. lume cat composes your images into a single picture right in the browser, with adjustable layout, cell ratio, gap, corners and background. Each photo is auto-cropped to fill its cell without distortion. It all runs locally — nothing uploaded, no watermark, no limits.

Why use lume cat's Collage?
- Auto-crop to fill, no distortion: each photo is center-cropped (cover) to fill its cell, so mixed portrait/landscape shots still line up — never stretched.
- Style it your way: gap, rounded corners and background (white / cream / pink / black / transparent) combine freely for a magazine, IG or comparison look.
- Nothing uploaded, no watermark, no limits: it composes entirely in your browser, so private photos never touch a server and exports come out clean.
Frequently asked questions
The current layout holds rows × columns photos (a 3×3 fits 9), filled left-to-right, top-to-bottom in the order you add them. To rearrange, change the add order and re-select.
No. Each image is center-cropped (cover) to fill its cell while keeping its aspect ratio — the overflow is trimmed, never stretched. To crop less, pick a cell ratio closer to your photos.
Yes. Choosing the “transparent” background exports a PNG with see-through gaps, handy for layering into other designs; the other backgrounds export a smaller JPG.
