GNU Gzip provides data compression and decompression utilities; the typical extension is ".gz". Unlike the "zip" format, it compresses a single file; as a result, it is often used in conjunction with "tar", resulting in ".tar.gz" or ".tgz", etc.

innoextract allows extracting Inno Setup installers under non-Windows systems without running the actual installer using wine.

LZFSE is a Lempel-Ziv style data compression algorithm using Finite State Entropy coding. It targets similar compression rates at higher compression and decompression speed compared to Deflate using Zlib.

XZ Utils is free general-purpose data compression software with high compression ratio. XZ Utils were written for POSIX-like systems, but also work on some not-so-POSIX systems. XZ Utils are the successor to LZMA Utils.

The core of the XZ Utils compression code is based on LZMA SDK, but it has been modified quite a lot to be suitable for XZ Utils. The primary compression algorithm is currently LZMA2, which is used inside the .xz container format. With typical files, XZ Utils create 30 % smaller output than gzip and 15 % smaller output than bzip2.

GNU sharutils is a package for creating and manipulating shell archives that can be readily emailed. A shell archive is a file that can be processed by a Bourne-type shell to unpack the original collection of files. This package is mostly for compatibility and historical interest.

ISA-L is a collection of optimized low-level functions targeting storage applications. ISA-L includes:

• Erasure codes: fast block Reed-Solomon type erasure codes for any encode/decode matrix;

• CRC: fast implementations of cyclic redundancy check. Six different polynomials supported: iscsi32, ieee32, t10dif, ecma64, iso64, jones64;

• Raid: calculate and operate on XOR and P+Q parity found in common RAID implementations;

• Compression: fast deflate-compatible data compression;

• De-compression: fast inflate-compatible data compression;

• igzip: command line application like gzip, accelerated with ISA-L.

LZO is a data compression library which is suitable for data de-/compression in real-time. This means it favours speed over compression ratio.

LZO is written in ANSI C. Both the source code and the compressed data format are designed to be portable across platforms.

This package provides a simple zip library based on miniz.

Clzip is a compressor and decompressor for files in the lzip compression format (.lz), written as a single small C tool with no dependencies. This makes it well-suited to embedded and other systems without a C++ compiler, or for use in other applications like package managers. Clzip is intended to be fully compatible with the regular lzip package.

FastJar is an attempt to create a much faster replacement for Sun's jar utility. Instead of being written in Java, FastJar is written in C.

This package provides the reference implementation of Brotli, a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.

The specification of the Brotli Compressed Data Format is defined in RFC 7932.

UnZip is an extraction utility for archives compressed in .zip format, also called "zipfiles".

UnZip lists, tests, or extracts files from a .zip archive. The default behaviour (with no options) is to extract into the current directory, and subdirectories below it, all files from the specified zipfile. UnZip recreates the stored directory structure by default.

SfArk extractor converts SoundFonts in the compressed legacy sfArk file format to the uncompressed sf2 format.

minizip-ng is a zip manipulation library written in C, forked from the zip manipulation library found in the zlib distribution.

xdelta encodes only the differences between two binary files using the VCDIFF algorithm and patch file format described in RFC 3284. It can also be used to apply such patches. xdelta is similar to diff and patch, but is not limited to plain text and does not generate human-readable output.

CBOR is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation. These design goals make it different from earlier binary serializations such as ASN.1 and MessagePack.

Extracts files out of Microsoft Cabinet (.cab) archives

Plzip is a massively parallel (multi-threaded) lossless data compressor and decompressor that uses the lzip file format (.lz). Files produced by plzip are fully compatible with lzip and can be rescued with lziprecover. On multiprocessor machines, plzip can compress and decompress large files much faster than lzip, at the cost of a slightly reduced compression ratio (0.4% to 2%). The number of usable threads is limited by file size: on files of only a few MiB, plzip is no faster than lzip. Files that were compressed with regular lzip will also not be decompressed faster by plzip, unless the -b option was used: lzip usually produces single-member files which can't be decompressed in parallel.

Archive huge numbers of files, or split massive tar archives into smaller chunks.

lbzip2 is a multi-threaded compression utility with support for the bzip2 compressed file format. lbzip2 can process standard bz2 files in parallel. It uses POSIX threading model (pthreads), which allows it to take full advantage of symmetric multiprocessing (SMP) systems. It has been proven to scale linearly, even to over one hundred processor cores. lbzip2 is fully compatible with bzip2 – both at file format and command line level.

This package provides a parallel implementation of gzip that exploits multiple processors and multiple cores when compressing data.

Pbzip2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 v1.0.2 (i.e. anything compressed with pbzip2 can be decompressed with bzip2).

Libzip is a C library for reading, creating, and modifying zip archives. Files can be added from data buffers, files, or compressed data copied directly from other zip archives. Changes made without closing the archive can be reverted.

unrar-free is a free software version of the non-free unrar utility. This program is a simple command-line front-end to libarchive, and can list and extract not only RAR archives but also other formats supported by libarchive. It does not rival the non-free unrar in terms of features, but special care has been taken to ensure it meets most user's needs.
