The jbig2dec project is no longer hosted here. Please see: https://www.ghostscript.com JBIG2 is a compression format for lossless and lossy encoding of scanned monochrome documents at moderately high resolution. It is very efficient in that domain, claiming 100:1 compression. jbig2dec is a decoder-only implementation of the format.

gzzzzzz enlarges a given file 6 times and writes it as a gzip file. It therefor can be "decompressed" (which makes it 6 times smaller) with the standard gzip. This shows that gzip (and deflate and any compression tool that uses one of them) but also, as I expect, any other compression format can be used to augment data significantly.

A lossless data compressor. It is a proof of concept for some ideas I had.

Lectures on Huffman Code mostly focus on creating the Huffman Tree and converting the given data into the new bitmap. But what about the informations needed to create the Huffman Tree? They must be stored as well. With this project I want to test some possibilities to store these data. gmp,h is needed to compile. See: http://gmplib.org/

hufc is a utility to compress or expand files using Huffman coding. It can use a 16-bit CRC or the IP checksum for error detection.

Gemc lets you prepare CD image files (such as BIN, CDI, NRG, CCD, or similar) so that they'll compress far better in programs such as WinRAR. HERE`S HOW TO USE IT: Run the CD image file (i.e. filename.bin) through GEMC to create an ECM file (i.e. filename.bin.ecm). Compress the ECM file (i.e. filename.bin.ecm) using your favorite compression program (i.e. 7Z,RAR,ZIP..). Back up, transmit via Internet, or whatever you normally do with CD images! When you want to burn the CD again,...

The linux e2compr package consists of a set of patches and utilities to provide transparent compression and decompression in the second extended (ext2) filesystem.

fpsc is a Fast Parallel Stream Compressor. It can use multiple CPUs to compress (gzip or bzip2) a data stream. (from stdin to stdout) It is built to achieve maximum throughput, everything else (especially memory usage) can be sacrified.

minidjvu is a DjVu encoder for black-and-white images.

Calculates differences of executable files using a randomized algorithm for matching with mismatches.

Lossless compression program with various algorithms included. Intended for large XML files, but can compress any files. Best results with block compression (BWT+MTF+RLE) on large block over alphabet of words.

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

rpmdiff is a utility to create a binary patch from one version of an rpm to another. This binary patch can then be distributed to end-users of a distribution who have installed the first version of the rpm and they will be upgraded to the second version.

PKC (PacKageCommander) is a package manager utility with ncurses and GTK+ interface. You can install/uninstall Debian or RPM packages, or you can configure, build and install a program from a source, and you can make a Debian or an RPM package, and it ca

LICOM is a compression/de-compression tool that sits in-between the browser and content from the server. It aims to facilitate compression of ASCII text, RTF, DOC, PDF, HTML, GIF, JPG, BMP and similar filetypes.

Rsync friendly encryption that runs on the UNIX command line. Encrypt a file and backup the changes to an untrusted host.

Xinstaller is a program written in C for Linux. It will allow you to make an installer file for your programs. The user will have only to start the executable and to answer some easy questions(mostly "next" :)).

Tcl Channel drivers for gzip'd and bzip2'd files. Read and wirte compressed files directly from within TCL. This library allows you to use two new commands (openBzip and openGzip) in your tcl scripts. Since they take exactly the same Options as the st

Compression/decompression library, capable of operating on a stream and intended to be used on systems restricted in code and stack size.

Iterative Compression Algorithm: trying to prove Shannon was wrong.

A port of zlib 1.1.4 to the Palm OS as a SysLib. Facilitates decompression/compression of infozip and PK-ZIP 2.x (.zip) as well as gzip (.gz) compression formats on the Palm PDA.

A set of Unixish tools allowing encrypted and compressed backups be done on exchangible media.

A simple project for use with SDL that loads a zipfile into memory and automatically converts all known files (such as text, graphics, fonts, and sounds) into data that is ready to be used in a game or multimedia project. It is the SDL equivalent of an A

TNT Mocha Backup Platform Independent backup utility written in Java. Uses ZIP files for data storage. Now supports file permission backup for restore by standard utilities in linux such as unzip.
