Instagram grid splitter. One photo. Nine posts.

Upload one big photo and we'll slice it into a 3×3 grid (or 3×2, 3×4, 3×5 — whatever you need) so it tiles seamlessly across your Instagram profile. Posts download in reverse order (last to first) so you can post them in the right sequence.

Drop a photo to split for Instagram
3240×3240 or higher works best — that's 1080 per tile. We'll suggest the best grid.
Your photos never leave this page. Conversion runs in your browser — no upload, no account, no watermark.
How it works

Three simple steps.

  1. 01

    Drop a photo (the bigger the better)

    We recommend 3240×3240 (or higher) for a 3×3 grid — that's 1080×1080 per tile. Lower-res photos work but look soft on profile.

  2. 02

    Pick a grid size

    3×3 is the classic. Use 3×2 or 3×4 if the photo isn't square. We auto-detect the best fit based on your aspect ratio.

  3. 03

    Download numbered tiles

    Numbered in reverse order (9 to 1) so the first one you post lands in the bottom-right corner of your profile, building up to a seamless image.

Questions about this tool

Good — here are the answers.

Why are the tiles numbered backward?

Instagram fills your profile grid bottom-up-and-leftward. To end up with the photo reading naturally (top-left to bottom-right), you have to post the bottom-right tile first. We number 9 → 1 so you just post in numeric order.

What size photo should I use for a 3×3 grid?

3240×3240 (or higher, square). That's 1080 per tile, which is Instagram's recommended post size. Lower resolution will look slightly soft on a high-res phone screen.

Can I split a non-square photo?

Yes — for a 3×2 grid use 3240×2160, for 3×4 use 3240×4320. We'll suggest the optimal grid when you drop the photo.

Will it work for Instagram Reels / Stories?

This tool is for the static grid (your profile page). Reels and Stories are full-screen, so use the resizer to crop to 1080×1920 instead.
