lz4-java - LZ4 compression for Java

  •    C

LZ4 compression for Java, based on Yann Collet's work available at This library provides access to two compression methods that both generate a valid LZ4 stream fast scan (LZ4) and high compression (LZ4 HC). The streams produced by those 2 compression algorithms use the same compression format, are very fast to decompress and can be decompressed by the same decompressor instance.

SharpZipLib - Compression Library in CSharp

  •    CSharp

#ziplib (SharpZipLib, formerly NZipLib) is a Zip, GZip, Tar and BZip2 library written entirely in C# for the .NET platform. It is implemented as an assembly (installable in the GAC), and thus can easily be incorporated into other projects (in any .NET language).

Zstandard - Fast real-time compression algorithm

  •    C

Zstandard is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder. It also offers a special mode for small data, called dictionary compression, and can create dictionaries from any sample set.

miniz - miniz: Single C source file zlib-replacement library, originally from code

  •    C

Miniz is a lossless, high performance data compression library in a single source file that implements the zlib (RFC 1950) and Deflate (RFC 1951) compressed data format specification standards. It supports the most commonly used functions exported by the zlib library, but is a completely independent implementation so zlib's licensing requirements do not apply. Miniz also contains simple to use functions for writing .PNG format image files and reading/writing/appending .ZIP format archives. Miniz's compression speed has been tuned to be comparable to zlib's, and it also has a specialized real-time compressor function designed to compare well against fastlz/minilzo. Please use the files from the releases page in your projects. Do not use the git checkout directly! The different source and header files are amalgamated into one miniz.c/miniz.h pair in a build step ( Include miniz.c and miniz.h in your project to use Miniz.

ZIPFoundation - Effortless ZIP Handling in Swift

  •    Swift

ZIP Foundation is a library to create, read and modify ZIP archive files. It is written in Swift and based on Apple's libcompression for high performance and energy efficiency. To learn more about the performance characteristics of the framework, you can read this blog post. Swift Package Manager is a dependency manager currently under active development. To learn how to use the Swift Package Manager for your project, please read the official documentation. The ZIP Foundation package uses the V4 Package Description API. To add ZIP Foundation as a dependency, you have to add it to the dependencies of your Package.swift file and refer to that dependency in your target.

7-Zip-zstd - 7-Zip with support for Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard

  •    C

Zstandard v1.3.7 is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder. Brotli v.1.0.7 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.

LZF Compressor- High-performance, streaming/chunking Java LZF codec, compatible with standard C LZF package

  •    Java

LZF-compress is a Java library for encoding and decoding data in LZF format, written by Tatu Saloranta. LZF alfgorithm itself is optimized for speed, with somewhat more modest compression. Compared to the standard Deflate (algorithm gzip uses) LZF can be 5-6 times as fast to compress, and twice as fast to decompress. Compression rate is lower since no Huffman-encoding is used after lempel-ziv substring elimintation.
