rarfile
RAR archive reader for Python
Decision gist · record as of 2026-08-14
Yes. rarfile is actively maintained, has no Python dependencies, carries a permissive ISC license, and fills a clear need for RAR archive support in Python. The requirement for an external decompression tool is a known and documented constraint, not a deficiency. Suitable for production use when the external tool dependency is acceptable.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- An external decompression tool (unrar, 7zip, unar, or bsdtar) must be installed on the system; archive parsing and non-compressed file reading work in pure Python, but compressed files require the external tool.
- Low install friction with no runtime dependencies.
- Actively maintained as of 2026-08-13 with recent releases.

What it is and what it does
rarfile is a Python module that reads RAR archive files following the interface style of the standard zipfile library. It handles both RAR3 and RAR5 formats, multi-volume archives, password-protected files, and Unicode filenames. Archive parsing and non-compressed file access are implemented in pure Python, while compressed file extraction delegates to an external tool such as unrar, 7zip, unar, or bsdtar.
The module is designed for developers who need to programmatically work with RAR archives in Python. It requires an external decompression tool to be installed on the system for extracting compressed content, but provides a straightforward API for reading archive metadata and accessing file contents without requiring additional Python dependencies.
Use it for
- Extract files from RAR archives in a Python application without calling command-line tools directly.
- Read metadata and list contents of multi-volume RAR archives.
- Access password-protected RAR files programmatically with password support.
- Process RAR archives with Unicode filenames across different operating systems.
- Migrate legacy code that works with zip files to also handle RAR format archives.
