Lz-string is a string compressor library for Python.

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

Zipfile2 is a backward compatible replacement to ZipFile. It provides handling of symlinks, and exception management.

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

This package provides a backport of the compression.zstd module for Python versions below 3.14.

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.

This package provides a pure Python decompression module for .Z files compressed using Unix compress utility. It's a maintained fork of https://github.com/umeat/unlzw.

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

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.

MultiVolumefile is a Python library that provides a file-object abstraction, making it possible to use multiple files as if they were a single file.

This package provides py7zr, which implements 7-zip archive compression, decompression, encryption and decryption in Python.

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 includes a set of generators for dynamically loading gzip data. It is geared towards dealing with data streams.

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.

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.

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

This package contains a very thin Python wrapper for libdeflate.

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 thin Python bindings to compression and decomporession algorithms implemented in Rust. This allows for using algorithms such as Snappy without additional system dependencies. The following algorithms are available:

• Snappy

• Brotli

• Bzip2

• LZ4

• Gzip

• Deflate

• Zstd

Python-LZO provides Python bindings for LZO, i.e. you can access the LZO library from your Python scripts thereby compressing ordinary Python strings.

This package provides utilities to handle AR files in Python.

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

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