About Spritefold
Spritefold rearranges character sprites into the sheet layout RPG Maker MV and MZ use: three frames by four directions per character, up to eight characters per sheet.
It starts from a common layout (4-frame walk strips, LPC walk rows or RPG Maker order) or a custom grid where you pick which cell plays each frame, and previews the walk at RPG Maker's default speed. 32 px art can be padded to 48 x 48 or scaled 2x. The right-facing row can be the left row flipped. It reads PNG, GIF and WebP and exports PNG with transparency.
It runs in the browser. The free version on its itch.io page exports one character at a time; the paid version, an HTML file that also works offline, adds batch export of a whole pack, eight-character sheets, saved mappings and object sheets.
