7-Zip Zstandard: High Compression and Fast Decompression for Files and Archives

Are you tired of dealing with large file sizes and slow compression speeds? Look no further than 7-Zip Zstandard. This open-source compression tool offers high compression ratios and lightning-fast decompression, making it a game-changer for file management and archiving tasks.

Features and Functionalities

Zstandard: With the latest version 1.5.5, 7-Zip Zstandard leverages the real-time compression algorithm Zstandard, which provides excellent compression ratios. It offers a wide range of compression and speed trade-offs, while boasting an incredibly fast decoder. You can choose from 22 different compression levels to achieve the desired balance between size and speed.
Brotli: 7-Zip Zstandard incorporates Brotli version 1.0.9, a versatile lossless compression algorithm. Brotli combines LZ77, Huffman coding, and 2nd order context modeling to deliver compression ratios comparable to the best general-purpose compression methods. It excels in speed and density and is an excellent choice for various file types.
LZ4 and LZ5: With LZ4 version 1.9.4 and LZ5 version 1.5, 7-Zip Zstandard offers lightning-fast compression and decompression for your files. LZ4 achieves compression speeds of up to 400 MB/s per core and features an extremely fast decoder, making it ideal for scenarios that require high-speed operations. LZ5 is a modification of LZ4, designed to trade compression speed for improved compression ratios.
Lizard: 7-Zip Zstandard leverages Lizard version 1.0, an efficient compressor with lightning-fast decompression. Lizard achieves compression ratios comparable to popular compression methods like zip/zlib and zstd/brotli, while maintaining a decompression speed of 1000 MB/s and faster. It offers various compression levels optimized for different scenarios, ensuring optimal performance for your specific use case.
Fast LZMA2: Fast LZMA2 version 1.0.1 is an optimized LZMA2 compression algorithm. It is up to 100% faster than the standard LZMA2 at higher compression levels, while still offering a slightly lower compression ratio. Fast LZMA2 uses parallel buffered radix match finding and optimizations from Zstandard, resulting in significantly reduced memory usage per thread.
