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.
Choosing a grid and proportion
Start with the structure: regular grid, large block, frame, corner accent, or mosaic. Then choose the cell proportion separately. The same layout can become square, landscape, or portrait without rebuilding it manually in an editor.
For catalogs and product lists, regular grids with even spacing are usually easier to scan. For covers, collections, and stories, asymmetric layouts work better because one image can lead the composition while the others support it.
Export and quality
The final collage is rendered locally with Canvas. JPG usually creates smaller files for photos, PNG preserves graphics and clean edges better, and WebP is useful when you need a balance between quality and size on platforms that support it.
4K or 8K output is useful for print and large screens, but it needs more memory. If the device slows down, reduce the long edge or the number of photos and export again.
