Split an image into an Instagram grid

How an Instagram grid post works

A profile feed shows three posts per row. A 3 × 3 grid splits your image into nine tiles that reassemble into one large picture once all nine are posted, a striking way to introduce a profile or break up a feed. The splitter cuts the image evenly and labels each tile by row and column so the order is unambiguous.

Posting order matters and runs backwards: Instagram puts the newest post first, so to keep the picture intact you upload the bottom-right tile first and the top-left tile last. Post all nine in one session so the grid never sits half-finished.

Square the photo first for clean tiles

Profile thumbnails are square, so for tiles that line up perfectly, start from a square image. Crop the photo to 1:1 before splitting and every one of the nine tiles comes out square too, with no part of the picture trimmed by Instagram afterward.

Prefer a panorama you swipe through in a single post? Switch the grid to 1 row and 3 columns to get three wide tiles, or open split into a grid to pick any layout.

Keep the tiles sharp

Upload each tile at a good size so Instagram does not over-compress it. A 1080-pixel-wide tile is plenty; if your tiles come out larger, that is fine. If a tile is heavier than you like, run the set through the bulk compressor to trim them in one pass before posting.

The whole split happens on your device, so the photo is never uploaded to a third party, and it stays private until you post it yourself.
