What this tool does
The collage builder combines multiple images into one file directly in the browser. It includes 28 base layouts: 2x2, 3x3, 4x4, 5x5, 2x3, 3x2, 4x5, and 5x4 grids plus asymmetric magazine-style layouts with large blocks, corner accents, frames, and mosaics. Cell proportion is selected separately: 1:1, 4:3, 3:4, 16:9, 9:16, 3:2, 2:3, 5:4, or 4:5. You can rotate the whole grid, swap photos, move photos inside cells, zoom and rotate individual photos, set gaps, padding, background color through a picker, per-photo corner radius, crop mode, output format, and final long-edge size at 1K, 2K, 4K, or 8K.
How to use
- Add photos through the upload area or drag them into the tool.
- Choose a base layout on the right: grid, hero block, corner accent, frame, or mosaic.
- Choose the cell proportion and rotate the whole grid if needed.
- Set output size, format, quality, background, photo corner radius, and spacing between images.
- To swap photos, click the first cell in the preview and then the second cell.
- Drag a photo inside its cell to reposition it, or hover it to open zoom, rotate, and reset controls.
- Download the finished collage as one file without uploading images to a server.
