Nine tiles, one picture
This page does one job: it cuts a photo into a 3 × 3 grid — nine separate image files that reassemble into the original once they are all on your profile. It is the layout behind almost every Instagram mosaic you have seen.
The split runs on a canvas inside your own browser. The photo is never uploaded, so an unposted grid stays yours until you publish it.
Post them backwards — the files tell you how
Instagram places your newest post in the top-left slot and pushes everything else right and down. That means a grid has to go up in reverse: the tile belonging in the bottom-right corner is posted first, and the top-left tile is posted last.
You do not have to work it out. The nine files come out named post-01 through
post-09 in posting order — post-01 is the bottom-right tile. Upload them in
numerical order and the mosaic assembles itself.
Getting this backwards is the single most common way a carefully planned grid ends up mirrored.
Only the top row is visible without scrolling
On most phones, a profile shows roughly the first three posts before the visitor has to scroll. In a nine-tile grid that is the top row — tiles post-07, post-08 and post-09, the last three you upload.
Design with that in mind. Whatever the picture is actually about — the face, the product, the headline — belongs in the top third, not the bottom. A grid with its payoff at the bottom is a grid most people never see.
Instagram's grid is 3:4 now, not square
Instagram changed profile thumbnails from square 1:1 to a taller 3:4 shape. A mosaic cut into nine perfect squares gets refitted into nine taller slots, and seams that lined up in your design may not line up on the profile.
Instagram lets you adjust the crop as you post, which is the moment to check each tile. And if you are planning a grid today, splitting with the Portrait 3:4 tile shape gives you tiles shaped like the slots they will land in.
Plenty of guides still say 1080 × 1080 squares. That was right for years. It describes the old profile.
Start from a big enough photo
Each tile is one ninth of the original. For tiles at Instagram's 1080 × 1080, the source needs to be at least 3240 × 3240 px; 4000 × 4000 or more gives you room to crop. Split a 1080 px photo into nine and each tile is 360 px — there is no fixing that after posting.
Keep faces, logos and text at least 80 px inside each tile. Instagram crops again on display, and anything near a seam is the first thing to go.
How fast to post
Nine tiles, three sensible paces:
- One a day — nine days. Each post gets a normal amount of reach, and the grid assembles gradually. The most common choice.
- Every two or three days — two to three weeks. Slower, but your feed does not look like one long upload session.
- All nine at once. The mosaic is up immediately. Individual tiles get almost no reach, and followers see nine notifications in a row.
Whichever you pick, do not stop mid-row. Post four tiles and the fourth sits alone with two empty slots beside it.
Plan the picture before you split
The tool cuts wherever the grid lines fall. It cannot move a face off a seam or rebalance a composition. Before splitting, open the photo and imagine two vertical and two horizontal lines through it — that is exactly where it will be cut. Anything important sitting on one of those lines will be divided across two posts.
Edit the whole photo first, too. Applying a filter to each tile separately produces nine slightly different images, and the difference shows most at the seams.

Questions people ask
Which tile do I post first?
The bottom-right one. Instagram puts each new post top-left and pushes the rest right and down, so a grid is built backwards. The files are numbered for you — post-01 is the bottom-right tile, post-09 is the top-left. Upload them in numerical order.
How big does my photo need to be?
At least 3240 × 3240 px, so each of the nine tiles comes out at 1080 × 1080. 4000 × 4000 or larger is better. A 1080 px photo split into nine gives 360 px tiles, which look soft on any modern phone.
Will Instagram's 3:4 profile grid ruin my nine-grid?
It changes how it looks. Instagram now shows profile thumbnails in a taller 3:4 shape instead of squares, so nine square tiles get refitted and the seams can shift. You can adjust the crop as you post each tile. If you are planning a grid now, choosing the Portrait 3:4 tile shape matches what the profile displays.
How long does a nine-tile grid take to post?
One tile a day takes nine days. Every second or third day takes two to three weeks. Posting all nine at once puts the picture up straight away, but each tile gets very little reach on its own.
What if I post something else halfway through?
Every remaining tile shifts one slot to the right and the picture breaks. Finish all nine before posting anything else, or pin the completed rows.
Can I use a photo that is not square?
Yes. Leave the tile shape on Square 1:1 and the tool centre-crops your photo before cutting, so all nine tiles are true squares. Check that nothing important sits near the edges before you split.
Is my photo uploaded to a server?
No. The split happens on a canvas inside your browser. The photo never leaves your device, and there is no account, no watermark and no server-imposed size limit.
I need a different number of tiles.
Use the full Image Splitter, which has presets for 3, 4, 6, 12 and 18 tiles as well as a custom grid up to 10 × 10.
