# Image Splitter

Split an image into an even grid of rows and columns and download every piece in one ZIP archive. Pick up to 20 rows and 20 columns; the tool distributes the pixels evenly, names each part by its row and column and saves it as a lossless PNG. It is popular for Instagram grid posts, puzzles, printing large posters on several sheets and slicing sprite sheets.

## Frequently asked questions

### How do I split an image into a grid?

Upload your image and enter the number of rows and columns, each from 1 to 20. The tool cuts the image into that many equal parts and returns them as PNG files in a single ZIP archive.

### How are the parts named?

Each file is named after your upload with its row and column, for example photo-r1-c2.png for the first row and second column. Numbers are zero-padded when there are ten or more rows or columns, so the files sort in order.

### What happens if the size does not divide evenly?

The tool spreads the leftover pixels across the grid, so neighboring parts differ by at most one pixel and no pixel is lost or duplicated. Joining the parts recreates the original image exactly.

### How do I make an Instagram grid post?

Crop the image to the shape you need first, for example 3:1 for one row of three posts, then split it into 1 row and 3 columns. Post the parts starting from the last one so they line up in your profile grid.

### What is the maximum number of parts?

Up to 20 rows and 20 columns, which is 400 parts. The image must have at least one pixel per part in each direction, and the archive may be up to 25 MB.

### Is quality lost when splitting?

No. Every part is copied pixel for pixel from the original and saved as a lossless PNG, including any transparency.

### Can I split an image into a single row or column?

Yes. Set rows to 1 to cut vertical strips side by side, or columns to 1 to cut horizontal strips from top to bottom. This is handy for panoramas and long screenshots.

### Which file formats can I upload?

JPEG, PNG, GIF, WebP, TIFF and AVIF images up to 5 MB are supported. Animated files are split using their first frame. Images larger than 4000 pixels on a side are scaled to fit 4000 pixels first.

### Can I cut pieces of different sizes?

The splitter always cuts an even grid. To cut rectangles of any size and position, use the Image Extract Region tool, which takes a list of coordinates and returns each region as its own file.

### Can I print a large poster with the parts?

Yes. Split the poster into as many rows and columns as you have sheets, print each part at the same scale and tape them together. Each part keeps the original resolution, so the print stays sharp.
