Tiles
Tiles are cut on exact pixel boundaries, and any remainder from a size that does not divide evenly is added to the last column and row rather than dropped — so the tiles always reassemble into the original with nothing missing. The ZIP is built in your browser and stored uncompressed, because PNG and JPEG data is already compressed and packing it again only costs time.
