How to use Image Splitter
An image splitter cuts a single picture into a neat grid of equal tiles you can use separately. The most popular reason is the Instagram grid or carousel, where one large image is sliced into 3, 6, or 9 squares that line up perfectly on a profile or swipe across a post. It is also handy for printing a poster across several sheets or breaking a large graphic into manageable pieces. This tool previews the cut lines over your image, lets you set the number of columns and rows, and exports every tile as a PNG bundled into one ZIP — all in your browser.
- Drop an image onto the upload area or click to browse.
- Set the number of columns and rows with the sliders.
- Check the grid preview shows the cut lines you want.
- Click Download to generate and save the ZIP of tiles.
- Post or print the tiles in row-and-column order.

Planning an Instagram grid
Instagram displays profile posts in a three-column grid, so grid murals are almost always built on multiples of three. A 3×1 split gives a single row that appears side by side; a 3×3 split makes a classic nine-square mural. The key is posting order: Instagram fills the grid from the top, newest first, so you upload the tiles in reverse — bottom-right last to appear top-left — or use the row-and-column names this tool assigns to keep track. Start from a square or 3:1 ratio source image so the tiles are not awkwardly tall or wide once they snap into the grid.
| Grid | Tiles | Use |
|---|---|---|
| 3 × 1 | 3 | Single carousel row |
| 3 × 3 | 9 | Profile mural |
| 2 × 2 | 4 | Simple quad split |
Keeping tiles aligned
For the pieces to reassemble perfectly, the splitter sizes tiles as evenly as the dimensions allow and lets the final column and row absorb any remainder pixels, so there are never gaps or overlaps. To avoid a thin mismatched strip, it helps to start from an image whose width and height divide cleanly by your chosen columns and rows — for a 3×3 grid, a size like 1080×1080 splits into nine exact 360×360 tiles. Each tile is exported losslessly as PNG to preserve sharp edges, and the ZIP keeps them together so you do not have to download nine files one at a time.
