python-python-snappy provides bindings to the Snappy library and can be used to compress and decompress files and streams. It can also be used directly from the command line.

This package provides utilities to handle AR files in Python.

This package provides a Python interface to the brotli package, an implementation of the Brotli lossless compression algorithm.

This package contains a very thin Python wrapper for libdeflate.

This package provides a Python interface to the brotli package, an implementation of the Brotli lossless compression algorithm.

This package provide a Python wrapper to EWAH compression bitarray method.

This package implement a pure Python module for uncompressing LZW files (.Z), such as the ones created by Unix's shell tool compress.

This package provides a pathlib-compatible Zipfile object wrapper. It provides a backport of the Path object.

Bitshuffle is an algorithm that rearranges typed, binary data for improving compression, as well as a python/C package that implements this algorithm within the Numpy framework.

This package aims to provide faster zlib and gzip compatible compression and decompression by implementing Python bindings for the ISA-L library.

This module provides an xopen function that works like Python's built-in open function, but can also deal with compressed files. Supported compression formats are gzip, bzip2 and, xz, and are automatically recognized by their file extensions. The focus is on being as efficient as possible on all supported Python versions.

pylsqpack is a wrapper around the ls-qpack library. It provides Python Decoder and Encoder objects to read or write HTTP/3 headers compressed with QPACK.

This package provides a modern and easy to use streamable zip file generator

In data compression, BCJ, short for Branch-Call-Jump, refers to a technique that improves the compression of machine code of executable binaries by replacing relative branch addresses with absolute ones. This allows a LZMA compressor to identify duplicate targets and archive higher compression rate. BCJ is used in the 7-zip compression utility as the default filter for executable binaries.

pybcj provides Python bindings to a BCJ implementation in C.

This package provides an implementation of the Branch / Call / Jump conversion filter by CFFI for Python.

PPMd is a compression algorithm library using the Prediction by Partial Matching statistical technique. It is used in RAR and 7-Zip as one of several possible methods.

pyzopfli is a straight forward wrapper around the ZlibCompress method of the the zopfli library.

This project provides Python bindings for interfacing with the Zstandard compression library. A C extension and CFFI interface are provided.

Pyppmd provides classes and functions for compressing and decompressing text data, using the Prediction by partial matching (PPM) compression algorithm variation H and I.2. It provides an API similar to Python's zlib/bz2/lzma modules.

The inflate64 package provides Deflater and Inflater classes to compress and decompress with the Enhanced Deflate compression algorithm.

This package provides python bindings for the lz4 compression library by Yann Collet. The project contains bindings for the LZ4 block format and the LZ4 frame format.

Blosc2 is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() system call.

Python-Blosc2 wraps the C-Blosc2 library, and it aims to leverage its new API so as to support super-chunks, multi-dimensional arrays, serialization and other features introduced in C-Blosc2.

Python-Blosc2 also reproduces the API of Python-Blosc and is meant to be able to access its data, so it can be used as a drop-in replacement.

Lz-string is a string compressor library for Python.
