Image Tiler
Tile an image into a grid with adjustable gaps and mirror repeat to hide seams, then export as PNG or JPG. Runs entirely in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
How it works
- Upload an image, or use the sample.
- Set the number of columns, rows, and the tile width.
- Optionally add a gap with a background colour, or turn on Mirror repeat to hide seams on non-seamless images.
- Download the tiled grid as a PNG or JPG, or copy it straight to your clipboard.
FAQ
What is this useful for?
Turning a small image, icon, or pattern into a repeated grid for a background texture, a print layout preview, or a seamless-pattern test.
Does the image need to be seamless to tile well?
No, but a seamless (edge-matching) image will tile without visible seams between tiles — a non-seamless image will show a repeating grid with visible tile boundaries, which is sometimes exactly the effect you want.
What determines the final image size?
Columns × tile width and rows × tile height (tile height is scaled automatically to match your image's aspect ratio) — the canvas grows to fit exactly that grid.
Is my image uploaded anywhere?
No — the tiling happens entirely in your browser using the Canvas API. Nothing is sent to a server.
Can I add spacing between the tiles?
Yes — the Gap slider adds space between tiles (up to 20% of the tile size) and the Background colour picker sets what shows through the gap, and behind any transparent parts of your image.
What does Mirror repeat do?
It flips every second column and row of tiles, so each tile edge meets a mirrored copy of itself instead of a repeated one — this hides visible seams on images that were not designed to tile seamlessly on their own.
Can I export as JPG or copy the result instead of downloading?
Yes — pick JPG from the Format dropdown before downloading, or use Copy image to put the tiled PNG straight on your clipboard for pasting elsewhere.
