Duplicate a PNG into a Grid
Repeat an image into a grid of copies — set how many columns and rows and the tool tiles the image into a single larger PNG. Handy for contact sheets, repeating patterns, sticker sheets, and mock-ups. Runs in your browser; nothing uploads.

Grid size and output dimensions
The output is the source image's width times the number of columns, and its height times the number of rows — so a 200×200 image at 3×3 becomes 600×600. Copies are placed edge-to-edge; if the source has transparent margins, they carry through and the tiles will appear spaced.
FAQ
How do I make a repeating pattern from one image?
Set the columns and rows and click Duplicate — the image is tiled into a single combined PNG. It runs in your browser.
I want a seamless repeating tile.
This repeats the image as-is. For packing several different images into a sheet, see Sprite sheet.
