Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder (see benchmarks below). Zstandard library is provided as open source software using a BSD license. Its format is stable and published as IETF RFC 8478. The negative compression levels, specified with --fast=#, offer faster compression and decompression speed in exchange for some loss in compression ratio compared to level 1, as seen in the table above. ...

Version 1.0.9 contains a fix to "integer overflow" problem. This happens when "one-shot" decoding API is used (or input chunk for streaming API is not limited), input size (chunk size) is larger than 2GiB, and input contains uncompressed blocks. After the overflow happens, memcpy is invoked with a gigantic num value, that will likely cause the crash. Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm,...

...It features an extremely fast decoder, with speed in multiple GB/s per core (~1 Byte/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. LZ4 library is provided as open-source software using a BSD license. This benchmark simulates simple "static content transfer" scenario such as OS Kernel compression or video game's static assets (text/images/tables/scripts/etc) which loading from Flash Memory / HDD / SSD. In this case, compression time is completely ignored. Because only content developers compress the data at once and usually they don't care about its computational cost. ...

Library and command line tools for XZ and LZMA compressed files

LAME is an educational tool to be used for learning about MP3 encoding. The goal of the LAME project is to improve the psycho acoustics, quality and speed of MP3 encoding. Note: we provide source code only!

7-Zip is a file archiver with a high compression ratio. 7-Zip works in Windows 11 / 10 / 8 / 7 / Vista / XP / 2022 / 2019 / 2016 / 2012 / 2008 / 2003 / 2000. You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip. And there is command line version for Linux and macOS. Most of the source code is under the GNU LGPL license. The unRAR code is under a mixed license with GNU LGPL + unRAR restrictions. Check the license...

Win32 and Win64 DLL to compress files in the standard Gzip format and also the new Gzip2, this format can compress files as large as 9.223.372.036 gigabytes and has also MD5 the integrity check, now also SHA512 too, now with support to multi-threads

Major looseless compression algorithms library and documentation. First project: Arithmetic, Huffman, LZ77, LZ78, LZW, RLE. Second project reimplements Deflate. Documentation explains major Entropy Compression Methods.

Moved to GitHub.com/gdraheim/zziplib/ The ZZIPlib provides read access on ZIP-archives. The library uses only the patent-free compression-algorithms supported by Zlib. It provides functions that transparently access files being either real files or zipped files, both with the same filepath

pngcrush and other tools for manipulating PNG (Portable Network Graphics) and MNG (Multiple-image Network Graphics) files.

FLAC is a free lossless compressed audio format which supports streaming and archival. The FLAC project maintains the format and provides a reference encoder/decoder and input plugins for several popular audio players.

Lossless compressor for multichannel 8,16 and 24 bits audio data, with the ability of password data protection. Being 'lossless' means that no data/quality is lost in the compression - when uncompressed, the data will be identical to the original.

liblzg is a minimal implementation of an LZ77 class compression library. The main characteristic of the library is that the decoding routine is very simple, fast and requires no memory.

gzx is a C library and a command line tool for fully GZIP-compliant file compression with fast random access read support. gzx includes a FUSE (filesystem in userspace) client that allows to access the compressed files with arbitrary applications.

Rar Expander is a MacOSX program which extracts the files contained in single or multi-volume RAR archives. It uses the official unRAR library internally so it is fully compatible with archives produced by WinRAR.

TclTrf is an extension library to the script language tcl, as created by John Ousterhout. It extends the language at the C-and Tcl-with ``transformer''-commands to encode and compress data. Based on the stacked channels of the tcl core (ability inter

Simple light-weight file compression and decompression utilities. Written in C and portable to all platforms. Simple compress and decompress subroutines can be linked and called within applications to compact or unpack data on the fly or stand-alone.

Flake is an open-source FLAC audio encoder.

NuFX or "ShrinkIt" archives are the de-facto standard in the Apple II (and A2 emulator) world. NufxLib is a full-featured library of functions that manipulate NuFX archives (.SHK, .SDK, .BXY). NuLib2 is a command-line utility built on top of NufxLib. THIS PROJECT HAS MOVED TO GITHUB https://github.com/fadden/nulib2

Basic Compression Library is a portable library of well known compression algorithms, such as Huffman coding, written in standard ANSI C. It is intended to serve as a set of building blocks for specialized compression algorithms.

The development of an open source Prince Of Persia Level editor for PC, a new game engine and complementary tools.

minihuff is a data compression library that enables the creation of a static frequency table to be stored at both ends of a connection. This allows effective compression even for very small pieces of data that maintain similar entropy characteristics.
