Koala-guided local collage maker
Build fast photo collages and mosaics in your browser. TileKoala keeps every image on your device while Koa helps shape clean grids, random mosaics, and geometric layouts.
Scaled to fit on screen, exported at the full canvas size.
Load a few images, adjust the layout options, and Koa will auto-render a fresh collage preview after a short pause.
Publish-ready overview
TileKoala helps creators turn a folder of photos into a polished grid collage, random mosaic, or shaped image composition in under a minute. Everything happens locally in the browser, so your images never leave your machine.
Create uniform grid collages, randomized mosaic walls, or shaped layouts built from hexagons, triangles, circles, and diamonds.
TileKoala is a local-only web app with no sign-up, no uploads, no dependencies, and no tracking. It works as a single HTML file opened directly in a browser.
Set your own canvas size up to 10000 by 10000 pixels, preview the result on screen, then download a PNG or JPEG collage ready for sharing, printing, or further editing.
