  • Supports optional transparent-border trimming and 90-degree rotation
  • Exports plist, JSON, or CSV metadata and indexed multiple atlases

• Where it doesn't

Our verdict on PyTexturePacker

PyTexturePacker is an open-source Python package for turning image files into sprite sheets or texture atlases. It is aimed at developers, particularly solo developers and small teams, who want atlas generation to fit into a programmatic workflow. The package is installed with pip and uses the MaxRectsBinPack algorithm. Its documented scope is a subset of TexturePacker’s features, so it is better suited to configurable packing tasks than to users seeking a broader authoring environment.

Packing controls are a central strength. Maximum texture width and height are configurable, with documented defaults of 4096 pixels each. Users can enable 90-degree sprite rotation and trim transparent borders, and set border, shape, and inner padding. Output image format is configurable, with PNG as the default. These options give developers control over how images are packed and presented in the atlas without changing the package’s focused, code-oriented nature.

The output can include metadata in plist, JSON, or CSV formats, and the package can create indexed multiple-atlas output using a filename placeholder. That makes it relevant when a project needs atlas data in one of those formats or needs packing split across multiple atlases. Support is offered by email. Choose PyTexturePacker if a Python-based, open-source MaxRects workflow and its documented packing and export options fit your needs; consider another tool if you need features beyond its stated subset or prefer a visual-first workflow.
