How to Make a Photo Collage
A collage does something a photo album cannot: it lets someone take in a whole set of images at a single glance. Six holiday photos in one frame tell a story faster than six separate files ever will. This tool arranges any number of photos into a grid, a row or a column, with control over the spacing, background and corners — and it adds no watermark, which is more than most free collage sites can say.
Add your photos
Drop in as many as you like. Reorder them by hovering over any photo in the preview and using the arrows.
Choose the layout
An automatic square grid, a fixed 2 or 3 column layout, a single row, or a single column - the preview updates instantly.
Style and download
Set the spacing, margin, corner radius and background colour, then download the finished collage at full resolution.
Choosing a Layout That Works
The grid is the default for a reason. Equal cells give every photo the same visual weight, which is exactly what you want when no single image is the hero — a set of holiday snaps, a product range, a team page. The automatic grid picks the squarest arrangement for the number of photos you have added.
A single row or column works differently. It implies sequence — before and after, step one through four, a timeline. It is also the right choice when the collage has to fit a specific shape: a wide banner, or a narrow column in a document.
On spacing: a small gap of ten to twenty pixels reads as intentional and lets each photo breathe. Zero gap creates a single dense mosaic, which can look striking but makes individual images harder to distinguish. And because each cell is square, photos are centre-cropped to fit — so crop them first with our crop tool if a subject sits near an edge.
Common Situations This Tool Solves
Sharing a set of photos as one image
Sending eight photos means eight attachments in an unpredictable order. One collage arrives as a single image, in the order you chose, viewable at a glance.
Before-and-after comparisons
A two-photo row places the before and after directly side by side, which is far more persuasive than asking someone to swipe between them.
Product ranges and mood boards
A grid gives every item equal weight, which is exactly right for a catalogue page, a design mood board or a range of colour options.
Social posts with multiple images
Some platforms crop or reorder multi-image posts unpredictably. A single collage image gives you complete control over what people see.
Frequently Asked Questions
How do I make a photo collage for free?
Drop in your photos, pick a layout, adjust the spacing and background, and download. Completely free, no signup, and no watermark is added.
Does it add a watermark?
No. Nothing is added to your collage at all - what you see in the preview is exactly what downloads, at full resolution.
How many photos can I add?
As many as you like. The grid expands automatically. Very large collages are limited only by your device's memory, not by any imposed cap.
Can I reorder the photos?
Yes. Hover over any photo in the preview and use the arrow buttons to move it earlier or later, or the bin icon to remove it.
Why are my photos cropped?
Each cell in the collage is square, so photos are centre-cropped to fit. If an important subject sits near an edge, crop the photo yourself first so the framing is what you want.
Are my photos uploaded to a server?
No. The collage is built entirely inside your browser using canvas - your photos are never uploaded, never stored, and never seen by anyone.
What spacing should I use?
Ten to twenty pixels reads as clean and intentional. Zero gap creates a dense mosaic, which can look striking but makes individual photos harder to pick out.
Can I have a transparent background?
Choose PNG as the format and the background colour will be preserved as set - PNG supports transparency, whereas JPG will always fill it with a solid colour.
What resolution is the collage?
Each cell is rendered at the quality setting you choose - up to 1000 pixels per cell, so a 3x3 collage at maximum quality is over 3000 pixels wide. Plenty for print.
Should I download JPG or PNG?
JPG for photo collages - the file is far smaller and the quality difference is invisible. PNG if you need lossless quality or a transparent background.
Does it work on my phone?
Yes. Open this page in Safari or Chrome, select photos from your gallery, and build the collage. Large collages will be slower on phone hardware.
Is this collage maker really free?
Completely free, with no limits, no watermark, no signup and no premium wall. Everything runs in your browser, so there are no server costs to pass on.
