Why use Ogg?

Choose Free Software!

RealPlayer, Windows Media Player, iTunes, and other popular players require people to use non-free software: controlled by companies, not by the users. The companies that control the software design it to restrict the users and spy on them. If you choose Ogg Vorbis and Ogg Theora, you can listen to audio and stream video using many different media players, including free software that respects your freedom.

Nothing to Lose!

You don't lose any technical quality with Ogg Vorbis. It can compress down to a smaller size than MP3 while still sounding good. Best of all, it is designed to be completely free of patents and does not require the use of proprietary software.
