Image Slicer (Grid Split)

Features

• Six grids: 3×3 (nine tiles), 2×2, 3×1, 1×3, 2×3 and 3×2
• Per-tile padding of 0, 4, 8, 16 or 32 pixels, on white, black or off-white
• The last tile absorbs any remainder, so no edge is left with a gap
• Zero-padded file names (-01 … -09) that sort in posting order
• PNG, WebP and GIF sources stay PNG (they may have transparency); others become JPEG
• All tiles produced at once, each downloadable on its own or all together
• Nothing is uploaded — slicing happens in the browser

How to use

1. Drop an image in
2. Pick the grid (3×3 by default) and the padding
3. Nine (or four, or six) tiles appear immediately
4. Download them one by one, or use Download all

FAQ

The tiles do not line up when I put them back together. Why?

Two reasons. The image was sliced flush while the platform inserts gaps between tiles, so the gaps cut through the content and it reads as misalignment — a little padding (8–16 px) shrinks the content back into the middle of each tile and the reassembled picture looks right. Or the original is not square, and forcing square tiles would stretch it; this tool does not stretch — it divides the original proportionally, so the tiles are rectangles too.

What are the 01, 02 in the file names for?

Posting order. Phone galleries sort by name, and `-1` sorts after `-10` in a string comparison, so the tenth image jumps to the front. Zero-padding to `-01` makes name order the posting order.

Are pixels lost in the slicing?

No. The leftover pixels go into the last column and last row, so the nine tiles together cover exactly the original. Making every tile identically sized would necessarily drop pixels somewhere; this tool chooses not to.

Is the image uploaded?

No. Slicing uses the browser's own canvas, entirely in local memory. The image never leaves the machine, and it keeps working offline.
