How to Split an Image for a Grid
- 1 Open the image on Windows or macOS and choose a grid - 3 columns for an Instagram feed, a 3x3 nine-post, or a custom row/column count.
- 2 Preview the cut lines and set overlap or margins so the tiles line up when published.
- 3 Export every tile in one go at full resolution, in the aspect your platform needs - no per-image compression.
Grids, Puzzle Posts and Carousels From One Photo
A wide panorama or a tall design looks best when it spans several feed posts. The splitter cuts it into perfectly-sized tiles:
Instagram 3-column grid
Split into equal slices so a single image spans your profile rows.
Nine-post puzzle
Cut a 3x3 layout for the classic grid-puzzle reveal.
TikTok / swipe carousels
Break a long design into slide-sized panels for a swipe post.
Custom rows and columns
Any MxN split, with margins and overlap to control alignment.
Why Split on the Desktop
Online splitters are quick but take liberties with your file.
Full-resolution tiles
No silent downscale - the slices keep the original pixel size.
No added watermark
Tiles come out clean, not stamped with the site's logo.
Batch & re-export
Set a preset and split many images, or re-cut later without re-uploading.
Works offline
Runs on your machine with no upload and no connection.

Frequently Asked Questions
How do I split an image into 9 for Instagram?
Choose the 3x3 nine-post layout, preview the cut lines, and export all nine tiles at once - each slice is sized so the posts line up into one image on your feed.
Can I make a seamless 3-column grid from a wide photo?
Yes. Split into three columns and add a little overlap so no detail is lost across the seams when the tiles publish side by side.
Does it keep the original resolution?
It does. Tiles export at the full pixel size of the source, unlike online splitters that quietly compress each slice.
Is my image uploaded anywhere?
No. The split runs on your Windows or macOS machine; nothing is sent to a server.
Is it free?
Free to download and try. Build a grid during the trial, and after it the app is a one-time purchase.
