Image Splitter & Cropper
Split an image into a grid or crop a region, then download as ZIP. No upload, fully private.
Your image is processed in your browser and discarded after download — never uploaded.
What is Image Splitter & Cropper?
Image Splitter & Cropper splits an image online into a grid — like a 3×3 for Instagram — or into fixed-size pixel tiles, then downloads every piece as a ZIP. It's free and runs entirely in your browser, with a live preview overlay so you can check the grid before cutting.
Key features
- Grid mode: split evenly into any rows × columns
- Fixed tile mode cuts exact pixel sizes for sprites and tilemaps
- Live preview with the grid overlaid on your image
- Downloads all pieces as one ZIP
- Tiles named name_r01_c01.png so they stay in order
How to split or crop an image into tiles
The Image Splitter cuts one picture into many pieces and bundles them into a ZIP. There are two very different reasons to do that: laying out a photo across a social grid so it reassembles into one big image on a profile, or chopping a sprite sheet and tilemap into the exact pixel cells a game engine expects. The tool handles both with two modes. Everything runs on your device using the browser's Canvas API — the image is never uploaded.
Steps
- Choose an image. Click the drop zone and pick a file. A live preview appears immediately with the cut lines drawn over it, so you can see exactly where the tiles fall before committing.
- Choose a mode and set the numbers:
- Grid (rows × columns) — divides the image evenly into the rows and columns you set, each from 1 to 20. A 3×3 grid (the default) is the classic nine-square Instagram layout; 1 row × 3 columns makes a wide panorama into a swipeable carousel.
- Fixed tile size (px) — cuts tiles of an exact pixel size, each side from 8 to 4096 px. Use this for game assets where every cell must be, say, exactly 32×32. If the image doesn't divide evenly, the tiles in the last row and last column come out smaller rather than being padded.
- Split & download. The tile count updates live as you change the numbers, so you know you'll get 9 pieces before you click.
How the tiles are named
Tiles are exported as PNG and named in row-major order: name_r01_c01.png, name_r01_c02.png, and so on across each row before moving down. The zero-padded numbers keep them sorted correctly in any file browser, which matters when you re-upload a grid in posting order or feed frames back into an engine in sequence. On desktop everything arrives as one ZIP; on mobile the tiles are passed to the share sheet to save individually.
Grid vs. fixed: which to use
Reach for grid mode when the whole image should be divided into a set number of equal pieces regardless of their pixel size — social layouts, contact sheets, cutting a poster into printable sections. Reach for fixed-tile mode when the pixel dimensions of each piece are what's fixed and the piece count just falls out of the math — sprite sheets, tilemaps, texture atlases.
Privacy
Your image is processed locally and discarded right after the download — it never leaves your device, and the split tiles are cleared from memory once the ZIP is saved. Nothing is uploaded before, during, or after the split.
Frequently asked questions
- What is the difference between grid mode and fixed-tile mode?
- Grid mode divides the whole image into a set number of equal rows and columns (1 to 20 each), which suits social layouts and contact sheets. Fixed-tile mode cuts pieces of an exact pixel size (8 to 4096 px per side), which suits sprite sheets where every cell must be, say, exactly 32x32.
- How are the tiles named, and will they stay in order?
- Tiles are PNGs named in row-major order: name_r01_c01.png, name_r01_c02.png, and so on across each row before moving down. The zero-padded numbers keep them sorted correctly in any file browser, which matters when you re-upload a grid in posting order.
- What happens if my image does not divide evenly in fixed-tile mode?
- The tiles in the last row and last column come out smaller rather than being padded to full size. Grid mode is different: it always splits the image evenly into your chosen rows and columns.
- Can I make a 3x3 grid for an Instagram feed?
- Yes. 3x3 is the default grid and produces the nine-square feed layout. For a swipeable panorama carousel, set 1 row and 3 (or more) columns instead.
- How do I get all the pieces, and is my image uploaded?
- On desktop the tiles download together as a single ZIP; on mobile they are handed to the share sheet to save individually. Nothing is uploaded: the split runs on your device with the Canvas API, and the image is discarded after download.
Privacy
Your image is sliced and packaged into a ZIP entirely on your device using the browser's Canvas API — nothing is uploaded before or during the split.
