How do I split an image into a 3x3 grid?

Load the image, tap the 3 × 3 preset and download. You get nine tiles named by row and column, each one third of the width and height, with any leftover pixels distributed so the pieces still join seamlessly.

How do I post a grid to Instagram in the right order?

Upload the bottom-right tile first and work backwards to the top-left, because the feed fills newest-first. Switch on reverse numbering here and the preview shows the upload order directly.

What size should each tile be?

For a social grid, aim for at least 1080 pixels on the short side per tile, which means starting from a 3240 pixel wide image for a 3 × 3. Smaller tiles get upscaled by the platform and look soft.

Does splitting reduce image quality?

Not with PNG or WebP, which are pixel-exact. JPEG tiles are re-encoded at high quality, so there is one generation of loss — negligible in practice but worth knowing if the source was already heavily compressed.

Can I split an image that is not evenly divisible?

Yes. The remainder is spread one pixel at a time across the first tiles, so a 1001 pixel width split three ways gives 334, 334 and 333 — every pixel accounted for, no visible seam.

Image Splitter

Slice an image into an even grid of tiles and download them as a ZIP, with every source pixel kept.

The Image Splitter runs entirely in your browser. Your picture is cut and zipped on your device, never uploaded.

À propos de Image Splitter

Cutting a picture into a grid is integer division with a remainder that has to go somewhere. Dropping it leaves a hairline of missing pixels down the right edge and along the bottom; this splitter spreads it one pixel at a time across the first tiles, so every source pixel survives and no tile differs from its neighbour by more than a pixel. That is what makes the pieces line up again when the grid is reassembled on a profile page. Presets cover the layouts people actually ask for — the nine-square Instagram grid, a panorama cut into three, a simple half-and-half — and the tiles come back as a ZIP named by row and column.

Exemple

Entrée

A 1080 × 1080 photo split 3 × 3

Sortie

Nine 360 × 360 tiles, named photo-r1-c1.png through photo-r3-c3.png

An odd width like 1081 gives tiles of 361, 360 and 360 — nothing is lost.

Erreurs courantes et dépannage

The tiles do not line up on a profile grid. — The feed cropped them. Instagram shows grid thumbnails square, so start from a square source and use a grid whose tiles are square too — a 3 × 3 of a 1080 × 1080 image works, a 3 × 3 of a landscape photo does not.
The uploaded grid appears in the wrong order. — Feeds fill from the bottom right, so tiles have to be posted in reverse reading order. Turn on reverse numbering and upload them in the order shown.
JPEG tiles have black corners where the image was transparent. — JPEG has no alpha channel. The tool fills transparent areas with white for JPEG output — choose PNG or WebP if you need the transparency preserved.
