Software that apply LZ77 and LZW dictionary based compression algorithm

Are there good applications (software) that perform dictionary based compression algorithm (LZ77 and LZW). And it is better if the application show: Compression ratio, Compression and decompression Time. I want to apply the compression in the text file and see the changes of file’s content after compressing.

Thanks

  • Probably the most widespread compression/decompression library is zlib, which uses LZ77. It is incredibly portable and runs on Linux and Windows. It also has a license with very few restrictions.

    Starting with Windows XP, Windows supports LZ compression natively (see related functions).
