Common ways to split an image
| Preset | Rows × columns | Pieces | Typical use |
|---|---|---|---|
| 2 side by side | 1 × 2 | 2 | A two-slide carousel, or a double-page scan cut into single pages |
| 2 stacked | 2 × 1 | 2 | A tall image or long screenshot cut in half |
| 2 × 2 | 2 × 2 | 4 | Quarters for printing big, or a simple puzzle |
| 3 × 3 | 3 × 3 | 9 | The classic Instagram profile grid |
| 1 × 3 | 1 × 3 | 3 | A panorama carousel people swipe through |
For anything else, set custom rows and columns from 1 to 10 each, for up to 100 pieces. That’s useful for printing a large image across several sheets of paper or cutting a sprite sheet into equal tiles.
Tips for Instagram carousels and grids
Carousels. A panorama split 1 × 3 becomes a carousel where each slide continues where the last one ended. To get pieces that match an Instagram post size exactly, start from an image with the right proportions: 3240 × 1080 pixels splits into three 1080 × 1080 squares, and 3240 × 1350 splits into three 1080 × 1350 portrait slides. Post the pieces in order, col1 first.
Profile grids. A 3 × 3 split makes nine posts that line up into one big picture on your profile. Because the newest post always shows first, post them in reverse: row3-col3, row3-col2, row3-col1, then row2-col3, and so on, finishing with row1-col1. Each later post shifts every piece along by one, so post new photos in sets of three to keep the picture lined up.
The profile grid shows each post as a 3:4 preview, which trims the sides of square pieces. For a grid that lines up cleanly, start from a 3:4 image: 3240 × 4320 pixels splits into nine 1080 × 1440 pieces, exactly the 3:4 post size.
For single photos, Resize for Instagram gets them to the standard post and story sizes.
How the pieces are cut
Every piece is cut straight from the original pixels with no resizing, so the pieces fit back together perfectly. Files are named by position, such as photo-row2-col1.png for the second row, first column, so the order stays clear after you unzip them. JPG and PNG images keep their format.
