| Data type | Multimedia container (usually audio) |
| MIME type | audio/ogg |
| Developer | Xiph.Org Foundation |
| Primary use cases | Web audio, open-source media distribution, game audio assets, streaming-friendly audio files (Vorbis/Opus), podcasts/voice (often Opus) |
OGG is an open multimedia container format (Ogg bitstream) commonly used for audio like Vorbis or Opus and designed for streaming-friendly delivery.
| Data type | Multimedia container (usually audio) |
| MIME type | audio/ogg |
| Compression | Container has no intrinsic compression; compression is provided by the embedded codec |
| Audio codec | Varies; commonly Vorbis or Opus; also possible: FLAC, Speex and others |
| Metadata | Vorbis comments (VorbisComment) are commonly used; Opus in Ogg uses an OpusTags comment header |
| Container format | Ogg bitstream (pages with capture pattern "OggS"), may multiplex multiple logical streams |
| Standard / Specification | RFC 3533 (Ogg Encapsulation Format v0); RFC 5334 (Ogg media types); codec mappings (e.g., Opus in Ogg: RFC 7845) |
| Typical file size | Varies widely by codec/bitrate (e.g., ~0.5–2.5 MB per minute is common across typical streaming bitrates) |
| Performance impact | Generally low decoding overhead; depends mainly on the embedded codec (Vorbis/Opus/FLAC) and bitrate |
| Year introduced | 2003 |
The OGG file format offers several advantages that make it suitable for common use cases.
The OGG file format has certain limitations that may affect its use in specific scenarios.
OGG is widely supported and plays on most devices by default.
As a binary container, it can carry arbitrary payloads; decoders must handle malformed streams safely—keep playback/conversion software updated
