Split image
Split an image into a grid or strips, with an explicit edge policy and local PNG and ZIP downloads.
How to use
Choose the image and wait for its validated preview. Select grid or strips, counts, ordering and edge policy, then export. Review each piece’s dimensions and cropped-pixel counts when cropping is selected. Download a PNG or the complete ZIP; preview shows four images per page.
A 5×3 image in a 2×2 grid with all pixels retained produces, row by row: 2×1, 3×1, 2×2 and 3×2. Cropping produces four 2×1 pieces and removes one rightmost column and one bottom row. Transparent padding produces four 3×2 pieces, preserving original pixels and filling the remainder with transparency.
Support & limits
No resizing or intentional color adjustment occurs. Keeping all pixels uses floor(position×size/count) boundaries, so dimensions differ by at most one pixel. Cropping leaves the remainder at right and bottom; padding uses ceil per cell and may produce fully transparent cells that remain in the ZIP within the budget. Without padding, row or column counts cannot exceed the available pixels along that side. Column-by-column order changes file numbering and ZIP order only. Names include piece, row and column numbers. Piece count, total pixels and conservative PNG reservation are checked before drawing surfaces are allocated; actual size is checked after each encode, without claiming a memory cap inside the browser encoder. ZIP stores PNGs without compression using a fixed archive date and does not preserve original metadata.
Common questions
Does splitting remove image pixels?
Only when you choose to crop the right/bottom remainder; the amount is shown explicitly. Choose varying sizes to retain every pixel without added borders, or transparent padding for equal cells within the total limit.
