Photo Collage Maker

How many photos work, and what shape to use

Two to nine is the practical range. Fewer than two is not a collage, and more than nine makes each cell too small to be recognisable, which defeats the purpose. The shape of the grid should match the arrangement: two images suit a side by side pair, four suit a square grid, and five or more work better in a layout that gives the first image more space. Deciding that before you start makes the result look deliberate rather than crowded.

Spacing and the background colour

The gap between images is what separates a tidy collage from one that looks like an accident. Even spacing, roughly a few percent of the total width, gives a consistent grid, and a background colour that matches the gap makes the separation look intentional. A white or neutral background suits most photographs, while a colour chosen to match the images themselves ties the collage together. What looks wrong is inconsistent spacing, where one row has a wide gap and the next has almost none.

• Use even spacing throughout. Inconsistency is what looks accidental.
• Pick a background that suits the photographs. White suits most, a matching colour ties them together.
• Leave a slightly larger margin at the outer edge than between the cells.
• A thin border on each cell can work, but only if it is the same width everywhere.

NoteA background that clashes with the images is more noticeable than any spacing mistake. Check it against a light and a dark image together.

Framing: fit or fill matters more than it sounds

Each cell either shows the whole photograph or crops it to fill. Fit keeps everything and leaves a gap where the image does not reach the cell, which suits images that must stay complete such as screenshots or group photos where cutting a person out would be wrong. Fill covers the cell completely and crops the overflow, which is what makes a grid look even. Mixing the two without thinking produces cells with inconsistent white bars, which is the most common flaw in a home-made collage.

• Fill every cell for an even, tidy grid. Some of each photo is cropped.
• Fit when no image may be cropped, accepting a background colour in the gaps.
• Do not mix fit and fill across cells unless the difference is deliberate.
• Pay special attention to faces when filling. A centre crop can remove one.
• Use the crop tool yourself on a problematic image before adding it, if you need control.

Exporting for where the collage will be used

A collage is a single image, so the export rules are the ordinary ones, with one extra consideration: the cell size. If the collage is going to be displayed small, the total dimensions and the compression budget both matter more than usual, because each cell is already a small portion of the image. If it is being printed, the cell size determines the effective resolution of every photo in it, so a small collage printed large means every image inside it is soft.

• For social sharing, JPG at balanced quality is a sensible default.
• Check each cell at 100 percent. A collage is only as sharp as its smallest cell.
• For a large print, export larger, because every cell resolution depends on the total size.
• PNG or WebP lossless if the images include text or sharp graphic edges.
• Keep the individual originals. A collage is a derivative of them.
