An image splitter cuts one picture into equal tiles. Presets cover the common jobs: a 3 × 3 grid that rebuilds the picture across nine posts on an Instagram profile, a 3 × 1 panorama for a swipeable carousel, and four equal parts. Or set any number of rows and columns from 1 to 10.
You can keep the image's own proportions or crop it around the centre so every tile is square (1:1), 4:5 portrait or 3:4. The preview shades what will be cropped, draws the cut lines and numbers each tile. For a profile grid the numbers are posting order: Instagram puts the newest post first, so tile 1 is the bottom-right piece and the top-left piece goes up last. For carousels the numbers run left to right. Files are named the same way (for example photo-01-r3c3.jpg) and download one by one or together as a ZIP. Tiles wider than 1080 px can be resized to Instagram's 1080 px width.
Limits: one image per run, up to 10 × 10 tiles, and every tile must be at least 16 px. The crop is always centred. Splitting doesn't post anything for you, and the grid only lines up on your profile if the nine posts go up in order with nothing posted between them. Animated GIFs use their first frame.
