1. Compression algorithm (deflate) The deflation algorithm used by gzip (also zip and zlib) is a variation of LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in the input data. The second occurrence of a string is replaced by a pointer to the previous string, in...

LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core, scalable with multi-cores CPU. It features an extremely fast decoder, with speed in multiple GB/s per core, typically reaching RAM speed limits on multi-core systems. ...
zlib algorithm usesDeflatemethod for compression andInflatemethod for decompression. Deflate method encodes the data into compressed data. Additionally, Inflate method decodes the inflate bits from the compressed data. zlib generates the original file without losing any bit of data: ...
Zstandard, orzstdas short version, is a fast lossless compression algorithm, targeting real-time compression scenarios at zlib-level and better compression ratios. It's backed by a very fast entropy stage, provided byHuff0 and FSE library. ...
deflate, zlib and gzip methods are aliases on compress without format argument.OptionsHere are the options with defaults values you can pass to zopfli:{ verbose: false, verbose_more: false, numiterations: 15, blocksplitting: true, blocksplittinglast: false, blocksplittingmax: 15 }...
This comparative study investigates three lossless compression algorithms: Zstandard, zlib, and LZ4. This study has a unique aim to provide insight into the performance of each algorithm to identify their strengths and weaknesses in different applications. Previous studies have been done; however, ...
