How to split an image into a grid of tiles

Steps

1. Open the Split into a grid tool and drop in your picture.
2. Choose the number of rows and columns, up to 10 by 10.
3. Press the split button.
4. Download the tiles, or all of them in one ZIP.

Grid posts and puzzles

For a social media grid, post the tiles in the right order so they join up on a profile. A 3 by 1 split gives a wide panorama in three posts, and 3 by 3 gives nine squares.

Tiles are named by row and column, for example photo-r1-c2.jpg, so you can tell which piece goes where.

No pixels lost

Every pixel of the picture lands in exactly one tile, so the pieces fit back together with nothing missing or doubled. If the size does not divide evenly, tiles differ by at most one pixel.

Tiles keep the picture format. Make the picture the shape you want first, because a tall picture gives tall tiles.

Tips

Crop the picture to the right shape first. A 3 by 3 grid looks best from a square picture, and a 3 by 1 panorama from a wide one with three times the width of its height.

Upload the tiles in reverse order if the site shows the newest post first, so they join up correctly on the profile. Check the layout on your phone before you share it.
