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.

PeaZip is a free file archiver utility and rar extractor for Windows and Linux, work with 150+ archive types and variants (7z, ace, arc, bz2, cab, gz, iso, paq, pea, rar, tar, wim, zip, zipx...), handle spanned archives and support multiple archive encryption standards. The project aims to provide a cross-platform, portable, GUI frontend for multiple Open Source technologies (7-Zip, FreeArc, PAQ, PEA, UPX) focused on file and archive management, and security

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.

snappy-java is a Java port of the snappy, a fast C++ compresser/decompresser developed by Google. It does fast compression/decompression around 200~400MB/sec, Less memory usage. SnappyOutputStream uses only 32KB+ in default, Compression/decompression of Java primitive arrays (float[], double[], int[], short[], long[], etc.) and lot more.

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.

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.

This is a rewrite (port) of Snappy writen in pure Java. This compression code produces a byte-for-byte exact copy of the output created by the original C++ code, and extremely fast. 
 
The Snappy micro-benchmark has been ported, and can be used to measure the performance of this code against the excellent Snappy JNI wrapper from xerial. As you can see in the results below, the pure Java port is 20-30% faster for block compress, 0-10% slower for block uncompress, and 0-5% slower for round-trip block compression. These results were run with Java 7 on a Core i7, 64-bit Mac.

SHARC is an extremely fast lossless dictionary-based compression algorithm. It is capable of an unprecedented compression speed of more than 500 MB/s per core on modern Intel CPUs ! It is scalable on multi core/multi CPU, developed in pure C99, and easily portable on many platforms.

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.

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. 

XZ for Java

Pixz (pronounced pixie) is a parallel, indexing version of xz. The existing XZ Utils provide great compression in the .xz file format, but they produce just one big block of compressed data. Pixz instead produces a collection of smaller blocks which makes random access to the original data possible. This is especially useful for large tarballs.
