Why convert PPTX to ODP?
Both PPTX and ODP use no compression scheme of its own, so the conversion mainly changes compatibility, not quality. The main reason to convert PPTX to ODP is compatibility: ODP opens in standard presentation software without a compatibility warning, while PPTX doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, ODP is usually the safer target.
