What is Image Grid Splitter?
An image grid splitter cuts a single photo into a grid of equally sized tiles. Content creators use it most for Instagram grid posts, where one image is spread across a 3×3 mosaic of individual uploads so the profile feed shows one seamless picture. This free tool renders your image on an HTML canvas, previews the cutting lines live, and exports every tile at full resolution as PNG — individually or bundled into a single ZIP. Everything happens locally in your browser, so photos never leave your device.
Key Benefits
- Live grid preview with cutting lines that update as you adjust rows and columns
- Full-resolution PNG tiles with zero quality loss from the original image
- Flexible grids from 1×1 up to 10×10 for feeds, collages, and contact sheets
- Single ZIP download with row-column filenames that sort in upload order
- Private by design — no uploads, no accounts, works offline after loading
Common Use Cases
- •Creating 3×3 or larger Instagram grid posts that display as one image
- •Cutting print sheets or contact sheets into equal photo tiles

- Upload your photo: Click the upload box or drag and drop any JPG, PNG, or WebP image. A live preview appears with the current grid overlay.

Frequently Asked Questions
What is an Instagram grid post and how does this tool help?
An Instagram grid post splits one large photo across multiple posts so the feed displays it as a single mosaic. This tool cuts your photo into an N×M grid of exact tiles — for example 3×3 — so each tile uploads cleanly and lines up in your feed.
Does splitting reduce the image quality?
No. Tiles are cut from the original image at full resolution using the canvas API and exported as lossless PNG. Nothing is recompressed unless your source image is already heavily compressed.
What size should my source image be for a 3×3 grid?
Use a square image for a uniform grid — for example 3240×3240 pixels gives 1080×1080 tiles, which matches Instagram recommended per-post size exactly.
Are my photos uploaded to a server?
Never. The tool reads your file locally, slices it with canvas in your browser, and generates the ZIP on your device. It even works offline once the page has loaded.
