Why convert AAC to OGG?
Both AAC and OGG use lossy compression, so the conversion mainly changes compatibility, not quality. The main reason to convert AAC to OGG is compatibility: OGG plays on virtually any device or app without an extra codec, while AAC 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, OGG is usually the safer target.
