7 zip compression ratio

7-Zip is a file archiver with a high compression ratio. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. High compression ratio in new 7z format with LZMA compression. Supported formats – Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR. Unpacking only: 7z, ZIP, RAR, GZIP, GZ, BZIP2, BZ2, TAR, CAB, ISO, ARJ, LZH, LHA, CHM, MSI, WIM, Z, CPIO, RPM, DEB, CPIO, DMG, FAT, HFS, LZMA, NTFS, SPLIT, SWM, TAZ, TBZ, TBZ2, TGZ, TPZ, VHD, XAR, XZ, Z and NSIS. For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip. Self-extracting capability for 7z format. Integration with Windows Shell. Powerful File Manager. Localizations for 70 languages.With today’s fast broadband rates, sending large files, or a large number of smaller files, via the Internet is easier than ever. Windows includes a compression program that allows you to zip files together and compress them into a single package. The problem is that it isn’t particularly good.7-Zip is a superior alternative. Here are five reasons why you should be 7z-ing your files rather than zipping them up…1. A dedicated file compression tool allows you to have more control over how you archive your files, the compression ratio, the container format, and whether or not you apply security layers. (7-Zip, for example, enables 256-bit AES encryption at the bank level).2. The widely used ZIP format is inefficient in comparison to newer formats.While 7-Zip supports ZIP files, the software’s native 7z format, which combines powerful LZMA and LZMA2 compression algorithms for enhanced file-squashing, yields better results. According to the creators of 7-Zip, 7z is often 30 percent to 70 percent more efficient than the original ZIP format.3. That isn’t to state that 7-Zip is just compatible with 7z and ZIP files. It can also compress files using the XZ, BZIP2, GZIP, TAR, and WIM formats.4. While 7-Zip’s archiving abilities are amazing, it can inflate far more file types than it can deflate, so you should be able to open the vast majority of archive files you get. ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR, and Z are among the formats supported.5. Have you noticed that RAR is supported? 7-Zip also supports the WinRAR file format, which is one of its main competitors.That’s all there is to ZIP and RAR. There’s no need to download additional software to extract data from those two file types.The main features of 7-Zip:High compression ratio in 7z format with LZMA and LZMA2 compressionSupported formats:Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIMUnpacking only: AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM, SquashFS, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR and Z.For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by

READMEThis is the Github Page of 7-Zip ZS with support of additional Codecs. The library used therefore is located here: Multithreading LibraryYou can install it in two ways:complete setup with additions within the GUI and a modified Explorer context menuonly the codec plugin that goes to your existing 7-Zip installation (no GUI changes and no additional Hashers)StatusCodec overviewZstandard v1.4.9 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.Levels: 1..22Brotli 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. It is similar in speed with deflate but offers more dense compression.Levels: 0..11LZ4 v1.9.3 is lossless compression algorithm, providing compression speed at 400 MB/s per core (0.16 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (0.71 Bytes/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio.Levels: 1..12LZ5 v1.5 is a modification of LZ4 which gives a better ratio at cost of slower compression and decompression.Levels: 1..15Lizard v1.0 is an efficient compressor with very fast decompression. 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.Levels 10..19 (fastLZ4) are designed to give about 10% better decompression speed than LZ4Levels 20..29 (LIZv1) are designed to give better ratio than LZ4 keeping 75% decompression speedLevels 30..39 (fastLZ4 + Huffman) adds Huffman coding to fastLZ4Levels 40..49 (LIZv1 + Huffman) give the best ratio, comparable to zlib and low levels of zstd/brotli, but with a faster decompression speedFast LZMA2
