DevConverter converts your archives online. Amongst many others, we support ZIP, RAR, TAR.GZ and 7Z. No need to download any software like WinRAR or 7ZIP.
GZ is an archive file format that uses gzip algorithm to compress data. It is frequently used in Unix based Operating Systems. It works similar to ZIP files but it is much compact than ZIP files. It uses the DEFLATE algorithm and combines the LZ77 and Huffman coding to compress files.
