Split an image into a grid

How to use it

1. Open an image.
2. Set the number of rows and columns. The dashed lines show where the cuts go.
3. Download the tiles as a zip.

Common uses

Carousel and grid posts. A wide panorama split into three 1:1 tiles (1 row, 3 columns) makes a swipeable carousel where each slide continues the last. Crop the panorama to exactly 3:1 first so each tile is square.

Printing large. A poster can be printed on ordinary A4 or Letter paper by splitting it into a grid and taping the sheets together. Work out the print size first: at 150 DPI, a single A4 sheet holds about 1240 × 1754 pixels.

Puzzles and teaching. Tiles make simple jigsaw or sequencing activities.

File names

Tiles are named by row and column, such as photo-r1-c2.png, so they sort correctly and you can always tell where a tile belongs.

If the image does not divide evenly, the tiles differ by a single pixel at most. Nothing is cut off.

Plan the shape before you split

Decide the tile shape first and work backwards. For three square tiles side by side, the image must be exactly three times as wide as it is tall. For a 3 × 3 grid of squares, it must be square itself. If the proportions are off, each tile comes out as a slightly squashed rectangle, and platforms may crop them again when they display the grid. Crop to the right shape first with the crop tool and the tiles will line up cleanly.
