Instagram Grid Maker - Free 9, 6, 3 Grid Splitter
Turn one photo into a 3x3 grid post for your Instagram feed. Free browser tool. No upload.
Pi7 turns one photo into a 3x3 Instagram grid post in your browser. Pick 9, 6, or 3 cells, hit Make Grid, and download every slice as a ZIP. Free, no signup, no upload. Use it for theme reveals, profile banners, product launches, and event recap posts.
The default 3x3 setting gives you the classic 9-cell feed grid. Switch to 3 rows by 1 column for a panorama strip. Switch to 3 rows by 2 columns for a 6-cell theme that fills two full rows of your profile.
How to Make an Instagram Grid Post in 4 Steps
- Upload your photo. Drop the file or click Select Images.
- Pick your grid size. Default is 3x3. Switch to 3x1 for a panorama or 3x2 for a 6-cell theme.
- Hit Make Grid. The tool slices the image in your browser in under a second.
- Download and post in reverse order. Save the ZIP. Post bottom-right first, then move left, then up.

Three Grid Sizes That Work on Instagram
- 3x3 (9 cells). The classic feed grid. Locks 9 photos into your profile as one visual block. Best for a theme reveal or a portfolio drop.
- 3x2 (6 cells). Two full rows of your profile. Lighter commitment than 9 cells but still reads as one image. Good for a product launch or event recap.
- 3x1 (3 cells, vertical panorama). One horizontal photo split into three feed posts. Great for landscape shots and storefront photos.
In our testing, a 3x3 grid comes out cleanest when your source is at least 3240x3240 pixels. That gives each cell 1080x1080 - the native Instagram square size.
Plan a Theme Across Multiple Grid Posts
A single 3x3 grid covers 9 feed slots. Two grids back to back cover 18 slots - your whole visible profile on most screens. Plan the colour palette and the photo subject before you split.
One pattern that works: alternate quote slides and photos so every other row breaks up the colour. Another pattern: build a content calendar where each grid post represents one theme (launch week, behind the scenes, customer story).
We tested a 3x3 split on a vertical food photo and the bottom row clipped half a plate. The fix was to use a square source (the Maintain Aspect Ratio toggle on this tool snaps your cropper to a square so this does not happen).
Puzzle, Checkerboard, or Rainbow Layouts
Pi7 splits the source image into equal cells. The layout you build with those cells depends on how you arrange them on your profile.
- Puzzle grid. One image cut into 9 cells. The grid only looks right after all 9 are posted in reverse order.
- Checkerboard. Alternate cells of the original image with solid-colour cells. Post 5 image cells and 4 colour cells.
- Rainbow. Tint each cell a different colour. Post the cells in colour-wheel order along the rows.
Pi7 handles the split. The choice of layout pattern is yours - keep it simple for your first grid post and try a checkerboard after you get the posting order right.
Your Photos Never Leave Your Browser
Your photos belong to you. We never see them. We never upload them. We never store them.
Most online grid makers send your photo to a server, slice it in the cloud, then hand back the cells. Pi7 does the opposite. The slicing runs locally through JavaScript and canvas. Your image stays on your device the whole time.
That means no signup, no email, no rate limit, no watermark. Open the page, make the grid, close the tab. Nothing stays behind.
Frequently Asked Questions
What grid sizes work best on Instagram?
A 3x3 grid is the standard 9-cell feed post. A 3x1 vertical strip works as a panorama. A 3x2 (6 cells) covers two full rows of your profile in one image.
Do I need to upload my photo to make a grid?
No. Pi7 slices the image in your browser. Your photo never leaves your device.
In what order should I post the grid cells?
Post bottom-right first, then move left along the row, then bottom-up. Instagram fills your feed grid in reverse upload order.
