Zippy is a pure Nim implementation of DEFLATE, ZLIB, GZIP, and ZIP data compression formats, aiming to be small, performant, and dependency-free.

...Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression. The specification of the Brotli Compressed Data Format is defined in RFC 7932. Brotli is open-sourced under the MIT License. You can download and install brotli using the vcpkg dependency manager.

Zip-Ada is a library for .zip archives. Full sources are in Ada and are unconditionally portable. Input and output can be any stream (file, buffer,...) for archive creation as well as data extraction. Task safe and endian-neutral.

AZip is a free Zip Archive Manager with unique features such as: built-in content Search, smart archive Update, archive Recompression. The goal is to keep the user interface as simple as possible and bother the user the least possible with options or useless gadgets.

Crunch is an image compression tool for lossy PNG image file optimization. Using a combination of selective bit depth, color palette reduction and color type, as well as zopfli DEFLATE compression algorithm encoding that employs the pngquant and zopflipng PNG optimization tools, Crunch is effectively able to optimize and compress images with minimal decrease in image quality. While it may produce file size gains larger than those produced by lossless approaches, the impact on image quality is often imperceptible, and optimized file sizes are still significantly lower than the original.

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.

an implementation of the Inflate decompression algorithm corresponding to deflate compression as used by gzip and compatible with RFC 1951 Written in Z80 assembly language, with memory paging support for the Sam Coupe

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.

...This console application uses the SevenZipSharp library with unbuffered I/O which gives all the options of 7zip without the memory problem. The supported compression algorithms are: Deflate, Deflate64, BZip2, Lzma, Lzma2, and Ppmd The supported archive formats are: SevenZip, Zip, GZip, BZip2, Tar, and XZ

czip is a unix based utility written for the cell broadband engine. It allows its users to compress files in gzip format. It uses Jean-loup Gailly's deflate algorithm and is based in part on pigz, Mark Adlers parallel version of zlib.

Microsoft .NET Stream-derived objects that wrap ZLib inflate and deflate as well as Base-64 functions (C++ Mixed Mode implementation)
