Levels 30.39 (fastLZ4 + Huffman) adds Huffman coding to fastLZ4.

Levels 20.29 (LIZv1) are designed to give better ratio than LZ4 keeping 75% decompression speed.

Levels 10.19 (fastLZ4) are designed to give about 10% better decompression speed than LZ4.It achieves compression ratio that is comparable to zip/zlib and zstd/brotli (at low and medium compression levels) at decompression speed of 1000 MB/s and faster. Lizard v1.0 is an efficient compressor with fast decompression. LZ5 v1.5 is a modification of LZ4 which was meant for a better ratio at cost of slower compression and decompression.

A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. It features an extremely fast decoder, with speed in multiple GB/s per core (0.71 Bytes/cycle). LZ4 v1.9.4 is lossless compression algorithm, providing compression speed at 400 MB/s per core (0.16 Bytes/cycle). It is similar in speed with deflate but offers more dense compression. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder.īrotli v.1.0.9 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. Zstandard v1.5.4 is a real-time compression algorithm, providing high compression ratios. only the codec plugin that goes to your existing 7-Zip installation (no GUI changes and no additional Hashers).complete setup with additions within the GUI and a modified Explorer context menu.The library used therefore is located here: Multithreading Library This is the Github Page of 7-Zip ZS with support of additional Codecs.
