Split an Image Into a Grid

Cut an image into an even grid of tiles. Pick the number of columns and rows (a 3x3 grid is popular for Instagram profile layouts), preview the cuts, and download every tile at full resolution. The tiles always cover the whole image with no gaps. Everything runs in your browser, so the image never leaves your device.

How to split an image into a grid

  1. Drop an image in, or click to browse.
  2. Set the number of columns and rows.
  3. Download the tiles individually or all at once.

Examples

Instagram 3x3 grid

A 1080x1080 image, 3 columns by 3 rows
Nine 360x360 tiles named by row and column

Frequently asked questions

Is my image uploaded anywhere?

No. The image is split entirely in your browser with the Canvas API and never leaves your device.

How do I post an Instagram grid?

Split into 3 columns, then upload the tiles in order from the top-left, posting the rightmost first within each row, so they line up on your profile grid.

What if the size does not divide evenly?

The tiles still cover the whole image. Each tile takes an equal whole-pixel size and the last column and row absorb any leftover pixels, so nothing is lost.

Are the tiles full quality?

Yes. Each tile is cropped from the original at full resolution. Export as PNG for lossless tiles, or JPEG/WebP for smaller files.

Can I download all the tiles at once?

Yes. Use Download all to save every tile, named by its row and column so they stay in order.
