SpriteMaster - Turn Videos into Game-Ready Sprite Sheets
SpriteMaster is a free, browser-based tool for game developers and pixel artists. Convert AI-generated animation videos into game-ready sprite sheets instantly, or merge and reorganize existing sprite sheets.
Video to Sprite Sheet
Upload any MP4, WebM, or MOV video. Extract frames at custom FPS, remove backgrounds with one-click chroma key, clean up edge halos, auto-crop and resize, then export as PNG sprite sheet, animated GIF, or ZIP of individual frames.
Sprite Sheet Manager
Upload multiple PNG sprite sheets. Automatically detect grid configurations, merge sheets together, reorganize frames with drag-and-drop, change layouts, and batch resize with multiple scaling modes (pixelated, smooth, multi-step).
