.ogg — Ogg Container
An open media container often used with Vorbis, Opus, Theora, and other Xiph codecs.
About this format
Ogg is a container. Audio files with .ogg often contain Vorbis or Opus, but the extension alone does not fully describe the codec.
Use Ogg for open media workflows. Use Opus inside Ogg for modern speech and music compression.
