astc-encoder-py
a python wrapper for astc-encoder
Decision gist · record as of 2026-08-14
Yes, if you need ASTC texture compression in Python. The package installs cleanly with prebuilt wheels across most platforms, has no known vulnerabilities, and carries an unrestrictive MIT license. However, the project is aging (last release 342 days ago) with low adoption (3 GitHub stars), so evaluate whether you need active maintenance or community support before committing to it for production use.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.7 or later; archspec is a runtime dependency.
- Medium install friction due to compiled wheels; prebuilt wheels cover most platforms including x86_64, ARM, PowerPC, and s390x on Linux, macOS, and Windows.
- Last release was 342 days ago; repository is active but aging.

What it is and what it does
astc-encoder-py is a Python wrapper around the ARM ASTC encoder library, exposing both low-level compression and decompression APIs. It lets you convert images to ASTC texture format (used in graphics pipelines) and back, with support for different color profiles, block dimensions, and quality settings.
The package supports Python 3.7 through 3.13 with prebuilt wheels for most architectures. It depends only on archspec. The binding is relatively new (first release October 2024) and sees infrequent updates, with the last release 342 days ago.
Use it for
- Compress game textures to ASTC format for mobile or console deployment.
- Convert ASTC-compressed textures back to standard formats for inspection or re-encoding.
- Experiment with different ASTC block sizes and quality settings to optimize texture memory usage.
- Automate texture asset preparation in graphics pipelines.
- Integrate ASTC encoding into batch image processing workflows.
