Conversion of zip files to 7z file format

You can easily re-pack various compressed archives from one format to another, by extracting the original file (in this case ZIP) and compressing it again to a 7Z format, which is what zip to 7z conversion pretty much represents. The difference is usually in the compression ratio and thus resulting file size.
