Split an Image Into a Grid
Cut a single image into equal tiles — a 3×3 grid for an Instagram profile mosaic, a 1×3 strip for a swipeable carousel, or any rows × columns for tiling a big print across several sheets. Tiles are named by row and column so reassembling or posting them in order is not guesswork. Everything happens in your browser.

How to split an image
- Drop the image in.
- Pick a preset, or set rows and columns by hand.
- Tick the square option if the tiles need to be square (social grids); leave it off to keep the original proportions (tiled printing).
- Click Split into tiles, then take them one at a time or as a zip.
Posting a grid in the right order
Instagram builds a profile grid from the bottom-right backwards, so the posting order is the reverse of reading order. For a 3×3, post r3c3 first, then r3c2, r3c1, r2c3, and so on, finishing with r1c1. Post them in one sitting: anything you publish in between lands in the middle of the mosaic and shifts every tile. Start from a square source — Make square pads a rectangle to 1:1 without cropping — so the grid does not lose the edges of your image.
Tiling a large print
Work backwards from the paper. Four A4 sheets in a 2×2 arrangement give you roughly A2; nine give you A1. Turn the square option off, split into that many tiles, and print each borderless at the same scale. Do the resolution maths first: an A1 print at 150 DPI needs about 3500×4900 px in total, so each tile of a 3×3 needs to be around 1170×1640 px. The quality checker will tell you what you are starting with.
FAQ
How do I post a 3×3 grid on Instagram?
Split with the 3×3 preset and the square option ticked, then upload the nine tiles in reverse order — Instagram fills a profile grid right-to-left along each row from the bottom, so the last tile you post ends up top-left. Tiles are named -r1c1 through -r3c3 (row, column) so you can work out the order without guessing.
What does the square option do?
It centre-crops the source to the grid's own aspect ratio before cutting, so every tile comes out square. Without it, tiles inherit the shape of the original — a 3×3 split of a 4:3 photo gives you nine 4:3 tiles, which is right for tiled printing and wrong for a social grid.
What if the dimensions do not divide evenly?
Tile sizes are floored to whole pixels, so up to a couple of pixels along the right and bottom edges may be dropped. It is invisible in practice and it guarantees every tile is exactly the same size, which matters more — mismatched tiles show up as a visible seam when they are reassembled.
Can I use this for a large print across several sheets?
Yes — that is a good use for it. Split into as many rows and columns as you have sheets, leave the square option off, and print each tile borderless. Set the print resolution first with Change DPI so each tile lands at the intended physical size.
Is my image uploaded?
No. The tiles are cut on a canvas in this page and handed straight to your downloads folder.
