Image Grid Splitter

Slice a photo into numbered tiles without losing edge pixels.

How it works

Split one image into a row-and-column grid and download every tile as a PNG in one ZIP. Uneven dimensions are distributed across the tiles so the complete photo can be reconstructed.

The source is auto-oriented. Integer boundaries use floor(index × size / count), ensuring no gaps, overlaps or missing edge pixels.
At most 64 nonempty tiles; original decoded photo limited to 16 MP. ZIP names encode row and column.
Outputs are PNGs with original EXIF/GPS removed. The ZIP includes a JSON manifest with the exact tile coordinates.
