Conversion of zip files to tar.gz file format

zip zo tar.gz conversion pretty much represents repacking between zip and tar.gz files. This can be done with plenty of file archivers. Some software might allow this directly, while  others you will need to first decompress the .zip file and then pack the data again to a .tar.gz file.
