Image Grid Splitter

About this tool

Posting one large image across a nine-tile social grid - every tile a piece of the whole - beats nine random photos every time. This tool slices any picture into a 3×3 grid (2×2 and 4×4 also available), numbers the tiles and outputs them in order so the grid reassembles the original. Non-square images are center-cropped to a square first (a no-crop even-split mode keeps the full frame for images that are already square).

Output as JPG (small) or PNG (lossless); the tiles download as one ZIP or individually. Everything happens on the browser canvas - the photo never leaves your device.

Common uses: profile-grid posts, microblog photo walls, slicing a banner for a shop header, poster tiles for physical posting, puzzle material.

Frequently asked questions

Why were the sides of my image cropped away?

Every tile is square, so a non-square image must be center-cropped to a square first to avoid distorted tiles. If you would rather keep the whole frame (tiles become rectangles and grids show padding), switch to the no-crop even-split mode.

In what order should I post the tiles?

The ZIP names tiles in row-major order (1 top-left, 9 bottom-right). Pick them in numeric order when posting; batch pickers that sort by filename line up automatically.

What are 2×2 and 4×4 for?

2×2 suits four-tile microblog layouts; 4×4 slices a poster into 16 pieces for physical tiling or finer web layouts. The tool is grid-agnostic - any even-split slicing task works.
