About the Collage Maker
Collage Maker puts two to nine pictures into framed cells on one canvas. Choose a grid, a big picture on the left, or a big picture on top, then pick a canvas for a square post, portrait post, landscape picture or story. Set the spacing, round the corners, choose a background colour, and click a cell to zoom in or slide the picture so the right part shows. Pictures are cropped to fill their frames, and the finished collage is a single flat image, so you cannot edit the photos again inside it. It runs in your browser, and your photos are not uploaded.

Pick a layout that fits your photos
A grid gives every picture equal weight, which works for a set of similar shots. If one photo is the star, choose Big left or Big top so it gets about 60 percent of the space while the others share the rest.
The grid handles odd numbers by stretching the last row: with five pictures you get three on top and two wider ones below. Try a couple of layouts before settling, because the preview updates instantly.
Sizes for Instagram, stories and print
Match the canvas to where the collage will be used. Square is the safe default for social posts and profile galleries. Portrait uses more of the screen in a feed. Story is tall and thin for full-screen viewing on a phone.
All four sizes are fixed pixel dimensions, not print sizes. For a smaller file afterwards, use Compress Image, or set an exact size with Image Resizer.
Spacing, corners and background
Spacing of 10 to 20 pixels looks tidy on most canvases; set it to 0 for a tight mosaic. Rounded corners of 20 to 40 pixels give a soft, modern look. The background colour is what shows between frames, so a dark colour makes bright photos pop.
- White background: clean and neutral.
- Black background: dramatic, good for colourful shots.
- A colour taken from one of the photos: ties the collage together.
Choosing what shows in each frame
Every photo is cropped to fill its cell, so tall photos lose some of their top and bottom in wide cells. Click the frame, zoom in a little, and use the arrows to bring the face or subject into view.
If a photo will not open, convert it first: HEIC to JPG handles iPhone photos. To cut a finished picture into tiles instead, see Image Splitter, and to join pictures without cropping, try Combine Images.

Frequently asked questions
How do I make a photo collage on my phone?
Open this page in your phone's browser, tap Select images and choose your photos, then pick a layout and canvas. Tap a picture in the preview to adjust its frame, and tap Download to save the collage to your phone.
How many photos can I add?
Up to nine. Two photos use a side-by-side or stacked grid, and from three onwards you can also choose a layout with one big picture. If you pick more than nine, the extra ones are ignored and you are told.
What size should a collage be for Instagram?
Square 1080 by 1080 pixels suits a standard post, Portrait 1080 by 1350 takes more room in the feed, and Story 1080 by 1920 fits the full-screen story format. Landscape 1920 by 1080 suits screens and video thumbnails.
Can I change the spacing and background colour?
Yes. Spacing sets both the outer margin and the gap between pictures, from 0 to 60 pixels. The background colour shows through the gaps, and rounded corners soften each frame. Type a hex code or use the colour swatch.
How do I change which part of a photo shows?
Click the picture in the preview to select it, drag the Zoom slider above 100%, then use the arrow buttons to slide the visible part up, down, left or right. At 100% the whole height or width already shows, so there is nothing to slide in that direction.
Are my photos uploaded?
No. The pictures are drawn onto a canvas inside your browser and the collage is produced on your device. Nothing is sent to a server.
