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 }...
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...

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, ...
