Collage Maker

Quick answer
Combine several photos into one image using a grid, a strip, or a mosaic with a large feature photo, with control over spacing, background color, and corner rounding.
What it does
What the collage maker does
Four layout modes cover the common collage shapes. Grid arranges photos into even rows and columns. Horizontal strip lines them up side by side in a single row, which suits a before-and-after sequence or a set of product angles. Vertical strip stacks them top to bottom instead. Mosaic gives the first photo a large 2 by 2 block in the top-left corner and fills the remaining cells around it, so one image leads and the rest support it. Every layout center-crops each photo to fill its cell, so nothing is stretched.
Beyond picking the layout, you control the gap between photos, the background color that shows through that gap, and a corner radius applied uniformly to every cell for a softer, rounded look instead of hard rectangular edges. All of this composites in real time in the preview, so you can see the finished layout before committing to an export.
The finished collage exports as either PNG, which keeps rounded corners and any transparency clean and lossless, or JPEG, which produces a smaller file for a collage made entirely of photographic content with no transparency to preserve.
Step by step
How to use it
- 01
Add your photos
Upload the images you want combined; order can usually be adjusted afterward.
- 02
Pick a layout
Choose grid, horizontal strip, vertical strip, or mosaic depending on how many photos you have and the shape you want.
- 03
Adjust spacing and style
Set the gap size, background color, and corner radius to taste.
- 04
Export
Choose PNG for a lossless result with clean rounded corners, or JPEG for a smaller file size.
Your images never leave your device
Real estate agents combining several room photos into one listing image, or someone assembling a private family photo collage as a gift before it has been shown to anyone, are both working with source photos they would rather not upload to a stranger service just to arrange them side by side. The compositing runs on a canvas in your browser, so the individual source photos never leave your device during layout.

Format and quality tips
- 01
Match aspect ratios within a grid layout
Grid mode looks most consistent when the source photos share a similar aspect ratio; mixing a tall portrait shot with a wide landscape shot in the same grid forces awkward cropping to fill each cell evenly. Every layout crops to fill its cells, so trim mixed shots to a similar shape first if a subject sits near an edge.
- 02
Keep gaps proportional to output size
A gap that looks right in a small preview can look oversized once exported at full resolution, or too thin to register at all. Check the gap at the actual export size, not just in the on-screen preview, before finalizing.

Frequently asked questions
01How many photos can I put in one collage?
There is no fixed cap in the tool itself; practical limits come from readability once a grid gets very dense and from your device memory when handling many large source files at once.
02What is the difference between grid and mosaic layout?
Grid gives every photo an equally sized cell in even rows and columns. Mosaic makes the first photo a large 2 by 2 feature block and fills the remaining cells around it. In both, each photo is center-cropped to fill its cell, so nothing is stretched.
03Should I export my collage as PNG or JPEG?
PNG keeps rounded corners and any transparent background pixel-perfect and lossless; JPEG produces a smaller file and suits a collage made entirely of photographic content with square corners and no transparency.
04Can I change the order of photos after adding them?
Yes, photos can be rearranged before export, which matters for strip layouts where the left-to-right or top-to-bottom order is visually meaningful.
05Why do my photos look cropped strangely in the grid layout?
Grid cells are a fixed shape, so a photo with a different aspect ratio than the cell gets cropped to fill it; mixing very tall and very wide photos in the same grid tends to produce the most noticeable cropping.
06Can I add a background color instead of leaving the gaps white?
Yes, the background color behind the gaps between photos is fully adjustable to any color you choose.
