Photo collage maker

What this tool does

Choose two to nine photos and they are arranged into a collage at once. Pick a layout: an even grid, a mosaic where one photo is large and the others frame it, or a strip of photos side by side or stacked. Set the shape (square, 4:5, 9:16 story, 16:9, 3:2 or A4), the size, the gap between photos, the outer border, the corner radius and the background colour. Each photo fills its cell; drag inside a cell to choose which part shows, zoom in with the slider, and swap photos by dragging the ⇄ handle onto another cell. Save the result as JPG or PNG. The photos are never uploaded.

Layouts and how many photos they suit

• Grids are the calmest: equal cells, nothing competes. Four photos make a 2 × 2, six a 2 × 3, nine a 3 × 3. Counts that do not make a full grid (5, 7, 8) are arranged in rows of nearly equal length, the fuller rows first.
• Mosaics give one photo the lead: a large picture on the left or on top with the others beside it, or, for nine, a large centre framed by eight.
• Strips read as a sequence, like a film strip or a photo booth: good for steps, before and after, or a moment in several frames.

Shapes and sizes

Choose the shape for where the collage will go:

For printing, choose A4 and 3508 px: that is 2480 × 3508 pixels, A4 at 300 DPI. The article on collage layouts explains how shapes, gaps and cropping interact.

Gaps and borders that look even

The gaps between photos and the border around them are computed in pixels of the saved file, and every cell edge is placed from the exact fractions of the layout and rounded once. That means two neighbouring photos always share an exact gap: a 12 px gap is 12 px everywhere, and the outer border is the same on all four sides. When gaps and borders are the same width the collage looks evenly spaced; a border larger than the gaps reads as a frame.

Steps

1. Choose or drop up to nine photos.
2. Pick a layout from the thumbnails, then the shape and size.
3. Adjust gap, border, corner radius and background.
4. Click a photo to select it: drag inside it to reframe, use the zoom slider, swap it with the buttons or by dragging the ⇄ handle onto another cell.
5. Download JPG (smaller, photos) or PNG (lossless).

Tips

• Photos are held at up to 2,560 pixels on their longest side, which is more than any cell needs at 4096 px; very large photos are reduced when they are added, so nine 48-megapixel photos do not exhaust the browser's memory.
• Faces near a cell edge get cut: drag the photo inside its cell to bring them back in.
• To crop or straighten a photo first, use the image crop tool; to split one large picture into a grid instead, the image splitter.
