Open the Collage Maker
Go to the Collage Maker. It runs entirely in your browser — no download, no account.
Upload your photos
Drag and drop 2–6 photos onto the upload zone, or click to browse. JPG, PNG, and WebP are all supported. Photos appear as numbered thumbnails.
Choose a layout
Layout options appear automatically based on how many photos you uploaded. Choose from side-by-side, grid, featured (one large + smaller), and more.
Adjust spacing and background
Use the spacing slider to set the gap between photos. Choose a background colour — white is classic, black gives a dramatic bordered look.
Select output size
Choose landscape, square, portrait, or wide format. Square (1080×1080) is ideal for Instagram posts. Landscape (1200×900) works for most general uses.
