Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger. Snappy is intended to be fast. On a single core of a Core i7 processor in 64-bit mode, it compresses at...

A differential compresor (or a binary diff) for huge files. Unlike other tools, e.g. xdelta3, it searches for matching data through the whole source file, even if it weights several gigabytes, while using much less memory (with default configuration approx 25x less than the size of the source file). Output files are not compressed, so you can use any compressor you like with great results. It is quite fast for very similar files (about the speed of hdd, however it reads input files twice) and not much worse on files with lots of differences.

This project has moved to GitHub https://github.com/Zipios/Zipios Zipios is a C++ library for reading and writing Zip archive files. Access to the data of individual entries is provided through standard C++ iostreams. A simple read-only virtual file system that mounts regular directories and zip files is also provided.

Slim is a data compression system for scientific data sets, a binary and a library with C linkage. Slim works with integer data from one or more channels in a file, which it can compress more effectively and more rapidly than general tools like gzip.

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.

...At Dropbox, the security and durability of your data are our highest priorities. As an added security layer, Lepton runs within seccomp to disable all system calls except read and write of already-open file descriptors. Lepton has gone through a rigorous automated testing process.

Multi-threaded HDF5 filter implementing the LPC-Rice codec. This lossless codec is intended to compress correlated signal data, such as image data, stored in HDF5 chunks. The codec/filter is optimized for both compression and decompression speed, but compression ratios are still comparable to JPEG-LS and CCSDS-123 codecs.

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.

This project has been moved to https://github.com/inikep/XWRT XWRT (XML-WRT) is a high-performance XML compressor (it also works with textual files). It transforms XML to more compressible form and uses zlib (default), LZMA, PPMd, or lpaq6 as back-end compressor. It is similar to XMill, but has many improvements.

KENS is a group of libraries that allow to compress and decompress data using the Kosinski, Enigma, Nemesis and Saxman formats. They are being programmed in C/C++ (VC++ for the Win32 version) and can be used by any application (even Win32 VB apps).

SEG-Y files need special compression because they don't compress well using gzip and the like. The code is cross-platform C++ using nothing else than standard system libraries. This is a spin-off from the OpendTect project (http://opendtect.org).

Tools for archiving, compressing and processing XML data.

PyramidWorkshop is an image-compression System based upon the scientific work of John Robinson (inventor of BTPC) about image-compression with adaptive linear predictors and is in average more efficient than PNG/JPEG2000.

StormRT is a real-time multi-resolution analysis and compression package for data compression and temporal feature detection over multiple timescales.

FreeArc combines best 7-zip and RAR features: auto-selected LZMA/PPMD/Multimedia compression, 1gb dictionary, exe/dict/delta data filters, updatable solid archives, SFXes, recovery record, AES+Twofish+Serpent encryption, Linux support and much more...

libarxx is a C++ archiver with advanced features, like data synchronization and merging of multiple archives. It provides an object-oriented view on a directory tree of data items and allows versioning, compressing and structuring in multiple ways.

DyConnect is a cross-platform networking library for C++. Features include: synchronized variables for rapid development of networked games, multi-threaded TCP/IP, low-level UDP sockets, support for IPv4 and IPv6, and data compression.
