Photo Collage Maker — Combine Images

Add two or more pictures and choose how to join them. Side by side scales every picture to the same height and lines them up in a row; Stacked scales them to the same width and puts them one under another; Grid gives every picture an equal cell of the shape you pick (square, 4:3, 3:4, 16:9 or 9:16). Spacing puts an even gap between pictures and around the edge, filled with the background colour, and the finished image downloads as PNG or JPG at the width you choose.

Side by side and Stacked never crop anything: the whole of every picture is kept, so pictures of different shapes give a row of equal height but different widths. Grid crops instead, because every cell has the same shape: each picture is scaled to fill its cell and the overflow is trimmed equally from both sides, the way a phone's photo grid shows thumbnails. Put the subject in the middle of the photo, or choose a cell shape close to your pictures, if nothing should be cut off. With Auto columns the grid is as square as the number of pictures allows (four pictures make 2×2, nine make 3×3); an incomplete last row is left-aligned.

Use the arrows under each thumbnail to change the order, which runs left to right and top to bottom. Up to 30 pictures can go into one collage. A very long stack is scaled down as a whole to stay under 16,000 pixels tall, a limit some browsers place on a canvas. Everything is drawn on a canvas in your browser; the photos never leave your device.
