Conversion of pdf files to rar file format

Alas, we do not know about any useful pdf to rar conversion at this time or why it should be done in the first place. But of course you can compress .pdf document using WinRAR (or other tool that supports RAR format) and create a .rar file from it, but that's hardly a conversion, just the usual file archiving business.
