TileKoala review
A free web tool for geometric mosaics and very large photo collages.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
TileKoala is a free, browser-based collage maker for creators building photo grids, randomized mosaics, and geometric image compositions. It is particularly suited to users who want direct control over tile-based layouts without installing software or creating an account. Photos are selected from the device, arranged on a customizable canvas, previewed in the browser, and exported as PNG or JPEG files.
Its main strength is layout control. TileKoala offers uniform grid collages, randomized tiled mosaics, and geometric arrangements built from hexagons, triangles, circles, and diamonds. Users can adjust canvas width and height, columns, gaps, tile size, shape, and background color. Support for canvases up to 10,000 by 10,000 pixels makes it a fit for unusually large web mosaics as well as standard collage work. The local browser workflow also keeps image selection and processing on the user's device, with no uploads or sign-up required.
TileKoala is more focused than a full photo editor. It does not provide text tools or broader editing features, so users looking for typography, image correction, or a wider composition toolkit should choose another product. Export is limited to PNG and JPEG, and downloaded files include a TileKoala credit in EXIF/XMP metadata. Choose TileKoala when geometric shapes, adjustable tile structure, large canvases, and local processing matter most; look elsewhere when a collage needs text, general photo editing, or a broader export workflow.
