About TextureAtlas Toolbox
A free and open-source tool for working with sprite sheets and texture atlases.
About the Project
TextureAtlas Toolbox started as a small Python script to batch-extract Friday Night Funkin' sprites for a Funkipedia showcase gallery. At the time there weren't any good tools for extracting spritesheets in bulk — the few that existed were either clunky, too complex, or could only handle one file at a time.
It has since grown into a desktop application with a Qt-based interface covering four main workflows: extracting animations from atlases, generating new atlases from loose images, aligning sprites in a visual editor, and optimizing images with color quantization and GPU texture compression. The project supports 16+ atlas formats and runs on Windows, macOS, and Linux.
