Instagram Grid Splitter — Cut One Photo Into a 3×3 Grid
Split a picture into 3, 6, 9 or 12 tiles that reassemble on your profile — numbered in the order to post them.
🔒 Runs in your browser — files never uploaded ⚡ No signup 💯 Free
Simplified layout on small screens — the full version is on desktop.
Turn one image into a grid of Instagram tiles: a 3×3 mosaic, a 3×1 banner across the top of your profile, or any layout up to 4 columns by 6 rows. The tool crops the image to the grid's shape, cuts it into equal tiles at Instagram's 1080-pixel upload width, and labels every tile with the order you need to post it in — because the grid fills from the top-left with your newest post, the tiles go up bottom-right first.
Square tiles for the classic grid, or portrait tiles for the rectangular grid Instagram introduced in 2025. All in your browser.
How to use Instagram Grid Splitter
- Drop the image. Wide panoramas suit a 3×1 banner; anything roughly square suits 3×3.
- Pick columns and rows and the tile shape. Move the position sliders if the automatic centre crop cuts the wrong part.
- Split — the preview shows the cut lines and the posting order on every tile.
- Download the ZIP and post the tiles in order: post 1st is the bottom-right tile, and the top-left tile goes last.
Posting order — the part everyone gets wrong
Instagram lays out your profile newest-first, left to right, top to bottom. So the tile that belongs top-left has to be your most recent upload, and the bottom-right tile your oldest. Post in reading order and the picture comes out mirrored and scrambled. Every tile here is named post-01, post-02… in upload order, and the ZIP lists them the same way, so you just work down the list. Post them in one sitting, without other posts in between, or the mosaic breaks.
Square or portrait tiles?
For years the profile grid showed square thumbnails, so a 3×3 mosaic was cut from squares. In 2025 Instagram switched the grid to portrait rectangles (3:4), which means square tiles now get their top and bottom trimmed on the profile. If your grid shows rectangles, choose the Portrait 3:4 tile shape so the mosaic lines up. The 4:5 option matches the feed's tallest post size, for people who care more about how each tile looks on its own.
Getting a clean result
- Start with a large image — a 3×3 grid needs at least 3240 pixels across to avoid upscaling.
- Faces on a cut line look odd. Nudge the position sliders so features fall inside tiles.
- Instagram adds a small gap between tiles; lines and text crossing tiles will break slightly. Designs with organic shapes hide this best.
- Post from the ZIP in order, and only the mosaic tiles — a story or reel in between does not matter, but another feed post does.
Need each tile at a different size, or a single cropped post? See the social media resizer and the crop tool.
Frequently asked questions
In what order do I post the tiles?
Bottom-right first, top-left last. Instagram shows the newest post top-left, so the tile that belongs there must be the final upload. Each file is named post-01, post-02… in upload order — just follow the numbers.
Square or portrait tiles?
If your profile grid shows square thumbnails, use square. Instagram moved the grid to portrait 3:4 rectangles in 2025 for most accounts; if yours shows rectangles, choose Portrait 3:4 so the tiles line up without being trimmed.
How big should the source image be?
At least the grid's total width: 3240 pixels for three 1080-pixel columns. Smaller images are enlarged, which looks soft. Panoramas work well for 3×1 banners; anything else, crop to roughly the grid's shape first.
Will there be gaps between the tiles?
Instagram draws a small gutter between posts, so straight lines crossing tile edges shift slightly. Images with natural shapes, gradients and textures hide it; fine text across a cut line does not.
Can I use this for a carousel or a banner?
For a seamless carousel, set rows to 1 and columns to the number of slides, and post them as one multi-image post in normal order (left to right). For a profile banner, 3 columns × 1 row, posted bottom-right first as usual.
