LZO 2.01 by Markus F.X.J. Oberhumer

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.

Here are some key features… 

Long Range ZIP 0.18 by Con Kolivas

Long Range ZIP is a compression program that can achieve very high compression ratios and speed when used with large files. It uses the combined compression algorithms of lzma for maximum compression, lzo for maximum speed, and the long range redundancy reduction of rzip.

It is designed to scale… 

rzip 2.1 by Andrew Tridgell

rzip is a compression program, similar in functionality to bzip2 or gzip, but able to take advantage long distance redundencies in files, which can sometimes allow rzip to produce much better compression ratios than other programs.

The original idea behind rzip is described in my PhD thesis (see… 

PNG Plug-In 1.1.6 by Michael Sweet

PNG plug-in provides Portable Network Graphics (PNG) file load & save modules for The GIMP. The plug-in supports all color modes and supports saving of interlaced images and setting the level of compression.

Using the PNG Plug-In:
Figure 1 shows the PNG save options window.
The Interlace toggle… 

mod_gzip 1.3.26.1a by Kevin Kiley

mod_gzip is an external extension module for the WWW's most popular web server arrowApache, created in autumn, 2000.

Its implementation allows for using the compression method arrowgzip for a significant reduction of the volume of web page content served over the arrowHTTP protocol.

Currently… 

La 0.4b by Michael Bevin

La is a Lossless Audio compression program. That is, in contrast to formats such as mp3, La program reduces the size of music without affecting the quality, as the uncompressed signal is exactly identical to the original.

However, the compression ratio is thus far lower than that for .mp3 files -… 

LibLZF 1.51 by Marc Lehmann

LibLZF is a very small data compression library. LibLZF library consists of only two .c and two .h files and is very easy to incorporate into your own programs. The compression algorithm is very, very fast, yet still written in portable C.

Last not least, it is freely usable, unlike most other comp… 

Flux 0.10.0 by Hans Petter Jansson

Flux is an easy-to-use crypto, compression, I/O, and memory management library.

Flux consists of utility APIs that apply compression and strong cryptography to I/O channels (file or network), do strong hashing, and exchange C structs in an architecture-independent fashion.

It also provides n-ary t… 

Bonk 0.6 by Paul Harrison

Bonk is a an audio compression program that operates in both lossy and lossless modes. The compression method Bonk uses is quite simple compared to other lossy formats (such as MP3), and is based on speech compression techniques. It is nevertheless capable of producing a high compression ratio while… 

RPM Delta Compression Virtual Update Repository 0.2.0 by Joe Desbonnet

RPM Delta Compression Virtual Update Repository is an experiment to explore the possibility of significantly reducing the bandwidth required to apply updates to a Fedora installation.

This software includes a server which provides a virtual update repository to clients such as yum, up2date, or ot… 

zlib 1.2.3 by Jean-loup Gailly

zlib is designed to be a free, general-purpose, legally unencumbered, lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is portable across platforms.

Unlike the LZW compression method used in Unix compress, the compression meth… 

cpp xstream 0.0.3 by Claudio Valente

cpp xstream is a C++ flexible stream library.

cpp xstream is a collection of several streambuf and iostream classes that allow a programmer to compress and decompress data transparently with gzip or bzip2, to serialize composite types to xdr, to encode or decode with base64, and to tee output from… 

SGI RGB Image File Plug-In 1.1.1 by Michael Sweet

SGI plug-in provides SGI image file load & save modules for The GIMP. The plug-in supports GRAY, GRAYA, RGB, and RGBA color modes.

Using the SGI Plug-In:
The Parameter Settings buttons control how much compression is applied to the image:
No Compression stores the image raw or verbatim.

RLE… 

Ext2 compression extension 0.4.45 by Paul Whittaker

E2compr is a small patch against the ext2 filesystem that allows on-the-fly compression and decompression. It compresses only regular files; the administrative data (superblock, inodes, directory files etc.) are not compressed (mainly for safety reasons).

Access to compressed blocks is provided f… 

UPX 2.90 by UPX Team

UPX is a versatile executable packer.

Here are some key features of "UPX":
excellent compression ratio: typically compresses better than WinZip/zip/gzip, use UPX to decrease the size of your distribution !
very fast decompression: ~10 MB/sec on an ancient Pentium 133, ~200 MB/sec on an Athlon… 

VTun 3.0.0 by Maxim Krasnyansky

VTun is the easiest way to create Virtual Tunnels over TCP/IP networks with traffic shaping, compression, and encryption.

In order to compile VTun you need some software packages.

Here are some key features of "VTun":
Encryption
Compression
Traffic shaping
VPN
Mobile IP
IP tunnel… 

JZlib 1.0.7 by Atsuhiko Yamanaka

JZlib is a re-implementation of zlib in pure Java. The first and final aim for hacking this was to add packet compression support to pure Java SSH systems.

Here are some key features of "JZlib":
Needless to say, JZlib can inflate data, which is deflated by zlib and JZlib can generate deflated d… 

RAR 3.60 Final by RARLAB

RAR software is a powerful tool allowing you to manage and control archive files. Console RAR supports archives only in RAR format, the names of which usually have a ".rar" extension. ZIP and other formats are not supported. Windows users may install GUI RAR version - WinRAR, which is able to proces… 

SCZ 1.6 by Carl Kindman

SCZ application is a simple set of compression routines for compressing and decompressing arbitrary data. The initial set of routines implement new lossless compression algorithms. Restoration (decompression) is perfect. It is called SCZ, for simple compression format. SCZ is intended as a subroutin… 

minihuff 1.0 by Jay Miller

minihuff is a data compression library with a simple new twist on Huffman coding. Instead of storing the frequency analysis for some set of data with the data itself, minihuff enables the creation of a static frequency table to be stored at both ends of a connection.

minihuff allows effective compr…
