TextureAtlas Toolbox is an all-in-one solution for working with texture atlases and sprite sheets.
Extract sprites into organized frame collections and GIF/WebP/APNG animations, generate optimized atlases from individual frames, or convert between 15+ atlas formats.
Perfect for game developers, modders, and anyone creating showcases of game sprites.
Formerly known as TextureAtlas to GIFs and Frames
