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...

LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core (>0.15 Bytes/cycle). 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...

Library and command line tools for XZ and LZMA compressed files

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.

Simple, fast implementation of LZW (Lempel–Ziv–Welch) data compression algorithm in C. - Console encoder/decoder tools - OS independent - Could be used in embedded projects - Works with raw code-stream LZW features: - Hardcoded dictionary size - Variable code size - Code search is performed by hash table and embedded in dictionary linked lists (encoder) - No dynamic memory allocation

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

This software zips and unzips a .txt file, using the Huffman encoding algorithm and the list and tree data structures. The result files are named zippedFile.txt and unzippedFile.txt and can be found at the same directory as the Text Zip executable file.

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.

Info-ZIP portable compression/archiver utilities (Zip, UnZip, WiZ, etc.)

Zip file alternative protection mechanism for passing zip files across public networks or to bypass scanning mechanisms of the contents.

Command-line tool for identifying and uncompressing a wide array of archive formats. It aims to unlock old and hard-to-find archive types.

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

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

Shoelacer generates C code to compress short strings based upon provided sample data. The resulting routines use small models with low memory overhead.

UPX Tool is a GUI for the popular UPX EXE Compressor. Windows Programs and Dlls, and DOS Programs can be compressed.

makeutil is a set of portable public domain programs designed to support C/C++ projects. It provides tools for build operations outside of the normal compile/link pipeline. It is designed to be unobtrusively included directly in your own project.

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

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 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

Help implement an industrial strength Burrows-Wheeler transform compressor! Initial release covers block-sort, MTF coding, RLE coding, Huffman coding
