How it works
Free layout
Add images by opening files, dropping them or pasting. Choose which side of the target the next images go on, then drag a tile onto another: dropping in the middle swaps the two, dropping at an edge places it beside.
Each tile has a fit. Crop to match fills the base image’s shape, Own shape keeps the whole image, and Matte fits it inside a white mat.
Grid mode
Grid mode lays every image in a near-square grid, or in the number of columns you pick. Each cell takes the size of the first image and the others are cropped to fill it. Drag tiles to reorder, or sort by name.
Output
Save as PNG, JPEG or WebP, or copy the picture to the clipboard. JPEG has no transparency, so empty areas are filled white. A very large composite is scaled down to at most 16,384 px a side and 64 megapixels.
