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 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 Python bindings to the Zstandard (zstd) compression library. The API is similar to Python's bz2/lzma/zlib module.

Blosc 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.

Blosc works well for compressing numerical arrays that contains data with relatively low entropy, like sparse data, time series, grids with regular-spaced values, etc.

This Python package wraps the Blosc 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.

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

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

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

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

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

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.

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.

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.

Lz-string is a string compressor library for Python.

This package provides utilities to handle AR files in Python.

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 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 modern and easy to use streamable zip file generator

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

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

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

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

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.
