The compression ratio is defined as the output (zipped file) size divided by the input file(original) file size. The goal of any compression algorithm is to achieve high compressionratio. There are different implementations of the LZW algorithm. The compression ratio of the LZW algorithm may have to do with the implementation and the input data file.
