Image Splitter

No — the image splitter runs entirely in your browser using the Canvas API. Your image is loaded, sliced and downloaded on your own device — it is never sent to a server, logged or stored. That makes it safe for private photos, and it keeps working offline once the page has loaded. Closing the tab clears everything.

Each tile is floor(width ÷ columns) by floor(height ÷ rows) pixels, and the last column and last row absorb any leftover pixels from the division. That means the tiles are as equal as the image size allows, no pixels are cropped away, and re-joining the tiles left-to-right, top-to-bottom rebuilds the original image exactly.

Yes — pick the 3×3 preset (or set 3 columns and 3 rows) to cut a square photo into the nine tiles of an Instagram carousel grid. Tiles are named by their position, TILE_r1_c1 through TILE_r3_c3, so you post them in the right order: upload row 3 first, then row 2, then row 1, so they line up top-to-bottom on your profile.

After you split, each tile has its own Download link, and there is a Download all (ZIP) button that packs every tile into a single ZIP archive. Each file inside is a PNG named TILE_r{row}_c{col}.png, so the grid position is clear. The ZIP is built in your browser, so it never touches a server.

JPG, PNG, WebP, GIF and BMP are all accepted as input. Every tile is exported as a PNG, which is lossless and keeps transparency, so the pieces stay pixel-for-pixel faithful to the original. Animated GIFs are flattened to their first frame, like any canvas-based tool.
