A collage is easiest to build when the layout is already sized for the right number of photos. These pages are grouped by photo count: two photos side by side, four in a 2×2 grid, six or nine shots on a single sheet. Pick a count and you'll see ready-made templates, each of which opens in the editor with a single tap.
Every layout comes from the MyCollages editor and runs right in your browser, on phone and desktop. Just drop your photos into the cells, tweak the background, spacing and proportions if you like, and download the result as PNG, JPG or PDF. No signup, no watermarks, and no limit on how many times you save.
