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.

•    Javascript

compact zlib, deflate, inflate, zip library in JavaScript

XZ for Java

•    Java

This aims to be a complete implementation of XZ data compression in pure Java. Single-threaded streamed compression and decompression and random access decompression have been fully implemented. Threading is planned but it is unknown when it will be implemented.

zlib - A Massively Spiffy Yet Delicately Unobtrusive Compression Library

•    C

zlib is a general purpose data compression library. All the code is thread safe. It is ported to different programming languages like Java, CSharp, Python and Perl.

lz4-java - LZ4 compression for Java

•    C

LZ4 compression for Java, based on Yann Collet's work available at http://code.google.com/p/lz4/. 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.

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.

Zopfli - Compression library from Google

•    C++

Zopfli Compression Algorithm is a compression library programmed in C to perform very good, but slow, deflate or zlib compression. The basic function to compress data is ZopfliCompress in zopfli.h. Use the ZopfliOptions object to set parameters that affect the speed and compression. Use the ZopfliInitOptions function to place the default values in the ZopfliOptions first.

flate2-rs - DEFLATE, gzip, and zlib bindings for Rust

•    C

A streaming compression/decompression library DEFLATE-based streams in Rust. This crate by default uses the miniz_oxide crate, a port of miniz.c to pure Rust. This crate also supports other backends, such as the widely available zlib library or the high-performance zlib-ng library.

lzfse - LZFSE compression library and command line tool

•    C

This is a reference C implementation of the LZFSE compressor introduced in the Compression library with OS X 10.11 and iOS 9. LZFSE is a Lempel-Ziv style data compression algorithm using Finite State Entropy coding. It targets similar compression rates at higher compression and decompression speed compared to deflate using zlib.

Redisson - Redis based In-Memory Data Grid for Java

•    Java

Redisson - distributed Java objects and services (Set, Multimap, SortedSet, Map, List, Queue, BlockingQueue, Deque, BlockingDeque, Semaphore, Lock, AtomicLong, Map Reduce, Publish / Subscribe, Bloom filter, Spring Cache, Executor service, Tomcat Session Manager, Scheduler service, JCache API) on top of Redis server. Rich Redis client.

pako - high speed zlib port to javascript, works in browser & node.js

•    Javascript

zlib's test is partially affected by marshalling (that make sense for inflate only). You can change deflate level to 0 in benchmark source, to investigate details. For deflate level 6 results can be considered as correct.

Info ZIP - Compressor Archiver Utilities

•    C

Info-ZIP's purpose is to provide free, portable, high-quality versions of the Zip and UnZip compressor-archiver utilities that are compatible with the DOS-based PKZIP.

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.

HU01 Decompression

Hotmail's DeltaSync protocol uses custom compression scheme known as hm-compression or HU01. It is very similar to DEFLATE encoding, which is standardized as RFC 1951, but the bit stream format is different. Earlier work on decompressing these streams was published by Daniel P...
