Split image into a grid

How to split an image into a grid

1. Add your imageChoose a JPG, PNG, WebP, AVIF, GIF or BMP file, or drop it on the box. Phone photos open upright.
2. Set the gridTap a quick grid such as 3 x 3, or type rows and columns. Switch to Custom size to cut pieces of an exact width and height in pixels. Dashed lines on the preview show every cut.
3. Split and downloadPress Split image. Download one piece, or all of them in a single ZIP. Files are named photo-01-01.jpg, photo-01-02.jpg and so on.

What is an image splitter?

An image splitter cuts one picture into several smaller pictures along a grid. A 3 x 3 grid gives nine tiles, a 3 x 1 grid gives three tiles side by side. Each tile is a normal image file you can post, print or edit on its own.

People use it to build an Instagram grid or carousel, to print a poster across several sheets of paper, to turn a long screenshot into readable pages, or to cut a sprite sheet into single images.

The cuts are made on the full-size original, not on the screen preview, so no tile is blurry. Nothing is uploaded: the splitting and the ZIP are made in your browser.

Equal grid or custom size

Equal grid divides the picture into the number of rows and columns you choose, from 1 to 20 each, with at most 100 tiles in total. Custom size works the other way round: you type the width and height of one tile and the tool works out how many tiles fit.

When the size does not divide evenly, nothing is dropped. In an equal grid the last row and last column keep the leftover pixels, so they can be a little larger. With a custom size they are the smaller leftover pieces. The panel tells you the exact size of those tiles before you split.

• Quick grids: 3 x 1, 1 x 3, 2 x 2, 3 x 3 and 4 x 4 (columns x rows).
• Output format: same as the original, JPG, PNG or WebP, with a quality slider for JPG and WebP.
• Transparent PNG pieces keep their transparency. If you choose JPG, transparent areas become white.

Split an image for an Instagram grid or carousel

For a profile grid of three posts across, use 3 columns. A 3 x 3 grid gives nine square-ish tiles when your photo is square, and a 3 x 1 grid is the usual choice for a wide panorama. Post the tiles in reverse order, last tile first, so they line up on the profile.

For a swipeable carousel, split a wide image into columns with 1 row, then post the tiles in numbered order. The file names are zero padded, so they sort correctly on every system, even with 12 or more pieces.

Crop your photo to the right proportions first with the Crop image tool if you need the tiles to be exactly square.

Large images and your device

The picture is decoded once and each tile is cut and saved in turn, so memory use stays close to the size of the final ZIP. Phones handle images up to about 24 megapixels, desktop browsers up to about 64 megapixels.

If a split runs out of memory, choose fewer pieces or the JPG format, which makes smaller files than PNG. HEIC photos from an iPhone are not opened here; convert them to JPG first.
