Image Splitter & Grid Slicer

No. Canvas decoding, slicing and ZIP creation run in the browser. Image history is not stored. Website ads and analytics follow the privacy information.

With zero overlap, integer cut boundaries partition the entire source exactly. Cell sizes can differ by one pixel when dimensions do not divide evenly. No resizing is applied to exported tiles.

The largest centered rectangle with equal whole-pixel square cells is used for the chosen rows and columns. Pixels outside that crop are removed. The preview shows the crop.

It extends each tile by up to 50 source pixels around internal cuts, bounded by the chosen crop. Outer tiles can have different sizes. Use zero for a seamless grid with no duplicated pixels.

The sequence portion of filenames counts from bottom-right toward top-left. Row/column labels and actual cut positions stay unchanged. It does not publish to a social service or guarantee its upload order.

PNG tiles preserve transparency. JPG tiles flatten transparent pixels onto white and use the selected quality. The overview grid and labels are not included in tile images.

Original dimensions, crop position, rows/columns/overlap, output format, ordering and each tile’s exact rectangle and filename. It helps reassemble or use the tiles in another project.
