TileKoala

What TileKoala is

TileKoala is a free browser-based tool for creating photo collages and mosaics while keeping image files on the user's device. It offers grid layouts with uniform, cover-cropped cells, as well as mosaics made from randomly sampled tiled crops. Shaped layouts include hexagons, triangles, circles, and diamonds. Users can add JPEG, PNG, WebP, GIF, or other formats supported by their browser, set canvas dimensions, and download a PNG or JPEG. The stated maximum canvas size is 10000 by 10000 pixels. TileKoala says it runs entirely in the browser, without uploads, external requests, sign-up, analytics, dependencies, or tracking. It can also be run as a single HTML file opened directly in a browser. Downloaded files contain an embedded EXIF/XMP credit linking to TileKoala; the page says no other additions are made. The maker is Small Red Flowers, based in Vancouver, British Columbia. The tool is intended for creators preparing collages to share, print, or edit further.
