Grid cutter: slice one photo into a 3×3 for your feed
You want that seamless feed look — one big image split across nine posts that line up into a single picture as you scroll. Cropping it by hand on your phone always drifts a few pixels and the seams don't match. Grid cutter splits the whole image into an exact 3×3 (or any rows × columns you choose), exporting each cell as its own file so it stitches together cleanly. It all runs locally in your browser — nothing uploaded, no watermark, no limits.
Grid Cutter Slice one image into a 3×3 grid so an Instagram or feed post lines up perfectly. It runs entirely in your browser — your photos are never uploaded — and it's free, watermark-free, with no limits.

Why use lume cat's Grid Cutter?
- Pixel-perfect alignment: it divides the real image dimensions exactly, so the seams meet — no hand-cropping drift.
- More than nine squares: 3×3, 2×2, or 1×3 strips all work — feed grids, collages and long-image segments in one tool.
- Nothing uploaded, no watermark, no limits: it cuts entirely in your browser, so private photos never touch a server and exports come out clean.
Frequently asked questions
On feed-style apps each photo in a multi-image post shows as its own square. To get the look where nine squares join into one picture as you scroll, you split the big image into an exact 3×3 and upload them in order. Cutting by hand rarely aligns — dividing by pixels does.
No. It just slices the original along a grid — no recompression, no resizing — so each cell keeps the original sharpness of its region. Want it crisper? Start from a higher-resolution image.
Yes. Set the grid to 3 rows × 1 column to split a tall image into top/middle/bottom thirds; use 1 row × N columns for a wide panorama.
Pick one photo, crop it to a 1:1 (or 3:4) square so the whole grid stays even, then run it through the grid cutter at 3×3. Download the nine cells, and in Instagram create a carousel post adding them in order — top-left first, then left to right, top to bottom. As people swipe, the squares line up into one seamless picture. Everything is cut in your browser, so the photo is never uploaded anywhere but Instagram.
