WinRAR can convert various archiving formats to RAR. But it has no support for reverse converting. So, you can only convert ISO to RAR, not vice verse.
But if you want to convert your archive to RAR format, you should launch WinRAR, choose your file and click on the Tools tab. Then select Convert archives from the drop-down list. Then choose a folder for converted archives and press OK. If you want to convert ISO to RAR, you should check ISO in the Archive types section.
