Instagram grid splitter & photo splitter
Image Splitter is a free online tool that splits a single photo into lossless pieces for Instagram. Pick the columns and the rows: a single row of 2, 3 or 4 pieces for a swipeable carousel, or a 3x3 grid of 9 pieces (2x3 for 6) for a profile mosaic; the pieces come out in Instagram ratios like 4:5, 1:1 and 9:16. Drag the frame to center the subject, or "Crop" to zoom in. Everything runs in your browser; your photo is never uploaded and the pieces download as lossless PNG.
What are carousel and grid posts?
A carousel is multiple images swiped through in a single post; split a wide photo into pieces and upload them in order, and a viewer's swipe reveals one large image. A grid effect instead lines the pieces up side by side on your profile grid for a panoramic look. Image Splitter cuts your photo into the right ratio and order for either format, so the pieces line up perfectly when reassembled.
3x3 grid splitter — 9 pieces for a profile mosaic
Set columns to 3 and rows to 3 and the photo is cut into 9 equal pieces, each in the Instagram ratio you picked — the classic profile mosaic. 2x3 gives 6 pieces, 4x4 gives 16, and any combination up to 4 x 4 works. One thing trips everyone up: a profile grid fills newest-first from the top left, so the pieces have to be posted backwards — bottom-right first, top-left last. Image Splitter numbers the cells and names the downloaded files in that upload order (01, 02, 03…), so you post them in the order they come off the page. The grid split is offered on 4:5 only, because that is the shape of a profile tile: the pieces land in the grid uncropped.
What size should the photo be for a 3x3 grid?
Nine 4:5 pieces together make one 4:5 picture, so start from a portrait photo. Instagram's best size for a 4:5 post is 1080 x 1350 px, which means a source of about 3240 x 4050 px gives every piece full size. A typical 12 MP phone photo cropped to 4:5 gives pieces of roughly 1000 x 1250 px — close enough that nobody will notice. Smaller photos still work; the pieces are just smaller and Instagram scales them up.
How to post the grid so it lines up
- Post the pieces in the order of the file names (01 first). That is bottom-right to top-left.
- Check your post count first. A profile grid has three tiles per row, so the mosaic only lines up when the posts already on your profile are a multiple of 3. Pinned posts sit in front of the grid and shift it too.
- Do not re-crop the pieces in Instagram's uploader; keep each one at the 4:5 frame it already has.
- Open your profile and compare it with the phone preview in the tool — they should match.
Grid, carousel or panorama?
- Carousel: one post, 2–4 pieces in a row, people swipe through. Pick columns 2–4 with one row.
- Grid mosaic: nine separate posts that form one picture on your profile. Pick 3 columns and 3 rows on 4:5.
- Panorama: a wide scene cut into a row, either as a carousel or across the top of your profile grid. The posting-order trap is explained in the panorama and carousel guide.
How to use it
- Add your photo (JPG, PNG, WEBP or iPhone HEIC).
- Pick an Instagram ratio: 4:5 portrait, 1:1 square, 9:16 story, 1.91:1 landscape.
- Pick the columns and rows: 2–4 columns for a carousel, or 3 x 3 for a nine-piece profile grid.
- Drag the frame to center the subject; zoom in with "Crop" if needed.
- Check the result in the phone preview, then download the pieces.
- Upload them to Instagram in order.
Tips
4:5 is usually the ratio that fills the most screen space for a carousel. Center the subject before splitting so a piece boundary doesn't cut through a face or the main object; in a 3x3 grid the cut lines sit at one third and two thirds, so keep faces away from them. Since the pieces stay lossless PNG, not a single pixel degrades. The cut is exact, so the seam between two pieces disappears when a viewer swipes — that is what makes a carousel look seamless rather than stitched. Every Instagram ratio is listed in Instagram photo sizes.

Frequently asked questions
How do I split a photo for Instagram?
Upload the photo, pick a ratio and piece count, drag the frame to center the subject, and download the pieces. Upload them to Instagram as a carousel, in order.
How do I make a carousel from one photo?
Split a wide photo into 2–4 pieces and upload them to the same post in order. As people swipe, one large image reveals itself smoothly.
How many pieces can I split into?
Pick any columns x rows up to 4 x 4. A single row of 2, 3 or 4 is the classic carousel; 3x3 gives the 9 pieces of a profile grid, 2x3 gives 6.
Can I split a photo into 9 for a 3x3 grid?
Yes. Set columns to 3 and rows to 3 and you get 9 pieces, each in the Instagram ratio you picked. The preview shows the mosaic as it will sit on your profile.
What order do I post a 3x3 grid in?
Backwards. A profile grid fills newest-first from the top left, so the BOTTOM-RIGHT piece has to be posted first and the top-left one last. The tool numbers the cells and the downloaded files in exactly that upload order, so you can just post them 1, 2, 3...
Which ratio should I use for a grid?
4:5 — it is the only ratio the row picker appears on. The Instagram profile grid shows portrait 4:5 tiles, so a 4:5 piece fills a tile exactly; a square one would be zoomed into it and the mosaic would drift. Other ratios keep the carousel split; only 4:5 offers rows.
Is this an image slicer / photo divider / post cutter?
Yes — slicer, splitter, divider and cutter all describe the same job, and this tool does it: one photo in, several correctly sized Instagram pieces out, with the cut lines lining back up seamlessly.
Does it reduce quality?
No. The pieces download as lossless PNG; not a single pixel is degraded.
Is it free and does it work on phones?
Completely free, no install. It runs in the browser on phone and desktop.
Are iPhone (HEIC) photos supported?
Yes, HEIC photos are converted and opened automatically.
How do I split a photo into 3 parts for Instagram?
Set columns to 3 and leave rows at 1. You get three pieces in a row for a swipeable carousel. Upload them to one post in order, and the picture continues as people swipe.
How do I split a photo into 6 pieces?
On the 4:5 ratio set 2 columns and 3 rows (or 3 columns and 2 rows). You get 6 pieces; the downloaded files are numbered in the order to post them.
What size should my photo be for a 3x3 grid?
Nine 4:5 pieces together make one 4:5 picture, and Instagram's best size for a 4:5 post is 1080 x 1350 px. A source of about 3240 x 4050 px gives every piece full size; a smaller photo works too, the pieces are just smaller. A typical 12 MP phone photo cropped to 4:5 gives pieces of roughly 1000 x 1250 px.
Why does my 3x3 grid look shifted on my profile?
A profile grid has three tiles per row, so a nine-piece grid only lines up when the number of posts already on the profile is a multiple of 3. Pinned posts also sit in front of the grid and push it. Count your posts (and pins) first, or post a few filler posts before the first piece.
