How to use it
- Drop the image you want to split (the higher the resolution, the better).
- Choose the number of rows (1–4, with 3 columns) and the grid format.
- Adjust the horizontal and vertical position to frame the picture.
- Click Split and download (ZIP), then post the tiles starting with number 1.
How a grid post works
Your Instagram profile shows posts in a grid three columns wide. If you split one wide or tall image into tiles and post them in the right order, the profile shows them together as one big picture, often called a puzzle feed or grid post.
The tool shows a preview of exactly how your profile will look, with a number on each tile. Instagram always places the newest post at the top left, so you have to start with the bottom-right tile. The files in the ZIP are named in posting order: 01-post-first.jpg up to the last one, post-last.jpg.
Everything is processed in your browser; your image is not uploaded.
New 3:4 grid or classic squares
In 2025 Instagram switched profile grids from squares to taller 3:4 thumbnails, while posts themselves can be 4:5 portrait images (1080 × 1350 px). The tool supports both:
| Format | Each post | What the profile shows |
|---|---|---|
| New profile grid (default) | 1080 × 1350 px (4:5) | The middle 3:4 part of each post |
| Classic square grid | 1080 × 1080 px | The whole square |
In the new format, a narrow strip on the left and right of each 4:5 post is hidden in the grid but visible when someone opens the post. The tool fills those strips from the picture when possible, and you can pick the side strip color for any area beyond the image edge.
Planning a grid post
| Rows | Posts | Best for |
|---|---|---|
| 1 × 3 | 3 | Panoramas and banners |
| 2 × 3 | 6 | Wide photos, announcements |
| 3 × 3 | 9 | A full-screen statement image |
| 4 × 3 | 12 | Very tall images, big launches |
Tips:
- Use a large source image. A 3 × 3 grid in the new format needs about 3240 px width; smaller images are scaled up and look soft.
- Post all tiles in one session, so other posts do not land in between and break the picture.
- Remember new posts shift the grid. Every later post moves your tiles along. Posting in multiples of three keeps the rows aligned.
- Make each tile work alone if possible, because followers see them one at a time in their feeds.
- Avoid text crossing tile borders where the spacing between grid cells can cut letters.
Carousel alternative
Instead of a grid on your profile, you can share a swipeable panorama as a single carousel post. Split a wide image into one row (1 × 3). In a carousel, the first image is the leftmost one, so add the tiles in the order 3, 2, 1: tile 3 is the left third of the picture and tile 1 the right third. Followers then swipe from left to right across the panorama.
A carousel keeps your profile grid tidy, while a grid post makes a bigger visual statement on your profile page. Some creators do both: a carousel for the feed and a grid for the profile.

Frequently asked questions
How do I split a picture into a grid for Instagram?
Drop the image, choose the number of rows and the grid format, then click Split and download. Post the tiles starting with number 1.
Which tile do I post first?
The bottom-right tile, number 1. Instagram adds new posts at the top left, so the grid builds up correctly.
What size are the tiles?
1080 × 1350 px for the new 3:4 profile grid, or 1080 × 1080 px for the classic square grid.
Is my image uploaded?
No. It is split in your browser.
Why are there strips at the sides of my posts?
In the new format, 4:5 posts are wider than the 3:4 grid thumbnail. The side strips only show when a post is opened.
