rif to jpg conversion represents export between two graphics format, thus it is certainly doable. In case of RIF/RIFF format and all its variants, it would be best to use Corel software, considering this is the main source of .rif files in first place.
If you do not have access to Corel software, you might try some of the dedicated graphics converters, but these might not support every variant of RIFF format.
