Gzip is a file compression and decompression utility that is used to compress and decompress files, or group of files, in order to save disk space. Gzip is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding. It compresses files using the Lempel-Ziv coding (LZ77) algorithm and Huffman coding. Gzip is widely used in Unix-like operating systems and is the standard compression program on Linux systems. Gzip can usually compress files to within 10% to 15% of the original size. Gzip is also an open source software and is available for free.
xz -0 is faster than gzip -9 and also compresses better.
