Decision gist · record as of 2026-08-14
Yes, if you need to work with Microsoft-compressed RTF data. The package is stable, has no dependencies, and carries permissive licensing. However, maintenance is aging with no recent updates; verify that it meets your RTF variant requirements before relying on it for new projects.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
compressed_rtf is a Python implementation of the LZFu compression algorithm used by Microsoft for Rich Text Format data. It provides two functions—compress() and decompress()—to encode and decode RTF streams according to the Microsoft RTF Compression Algorithm specification. The package has no runtime dependencies and works on both Windows and POSIX systems.
The library is useful when working with RTF data that has been compressed using the Microsoft format, such as email attachments or Office document streams. It implements both the compressed (LZFu) and raw (MELA) encoding variants, allowing round-trip conversion between compressed and decompressed RTF representations.
Use it for
- Decompress RTF data embedded in Microsoft Exchange or Outlook email messages
- Convert between compressed and uncompressed RTF formats for document processing
- Extract readable RTF content from binary streams that use LZFu compression
- Integrate RTF compression/decompression into document conversion pipelines
