In kde4 there was the option to compress files to rar format directly with the contextual menu. This option disappeared in plasma 5 (I think because rar is non free?)
This Service menu adds the options to compress to rar and 7zip formats. Is based on the kde4 Service menu and uses ark.
It will create a second "compress" submenu on your contextual menu. I couldn't find the way to fuse them together.
