How to split an image into a grid

  1. Drop your image onto the tool or click to browse.
  2. Pick the number of rows and columns. The preview shows the cell grid overlaid on your image.

  4. Download selected cells individually, all together as a ZIP, or as a multi-size ICO.

Common use cases

  • Slicing a sprite sheet into individual icons at the exact grid dimensions the artwork was designed at.
  • Creating Instagram grid layouts where a single image is split into 3x3 or 3x4 for sequential posts.
  • Cutting a reference photo into study-friendly thumbnails for an art drill.
  • Exporting icon sheets as multi-size ICO files for Windows or web favicon use.

Frequently asked questions

What is the ICO export for?

It produces a Windows-compatible .ico containing multiple sizes of each selected cell (16, 32, 48, 64, 128, 256 px). Drop it into /favicon.ico for instant multi-resolution favicon support.

Can I grid up to very large sizes?

The tool supports grids from 1x1 up to 20x20. Larger grids are supported but become unwieldy to select; above 10x10 consider scripting.

What output formats are supported?

PNG, JPG, WebP, AVIF and ICO. PNG is the default and preserves transparency.

Is my image uploaded?

No. Splitting happens in your browser.

About grid splitting

Grid splitting is the process of cutting a single image into multiple smaller pieces laid out in rows and columns. This tool lets you choose any grid from 1×1 up to 20×20, preview it visually, select the exact cells you want to keep, and export them in bulk. The multi-size ICO output generates a Windows-compatible .ico containing 16, 32, 48, 64, 128, and 256 pixel versions of each selected cell.
