PNG sheet: 20 MiB per-file ceiling · 16 MiB total with companion JSON

Up to 4096 px per side, 1,048,576 pixels per frame and 4,194,304 combined frame pixels. Sheets: 4,194,304 pixels. Up to 256 frames or grid cells.

Optional ForgeSprite frame JSON, up to 512 KiB. Adding it selects metadata mode; replacing the PNG clears it. Older versions may not read tight, trim, extrusion or omitted-edge metadata.

Set exact frame boundaries, then preview. Incomplete edge cells are rejected by default; choose Omit with warning to discard right/bottom remainders.

Changing settings clears previous downloads. Export again to update them.

How to use this tool

Choose a PNG sheet
Add a sheet and optional frame JSON. Use metadata for irregular or trimmed atlases rather than guessing a grid.

Preview the selected geometry. Check the grid overlay and individual crops before choosing frames.
Name and download
Set a filename prefix and slice selected frames into a PNG ZIP with a sheet PNG and JSON. ZIP paths are normalized and numbered; incomplete edge cells are rejected or omitted according to your setting.
