Convert Opus to OGG Online Free
Convert Opus audio to OGG Vorbis format for game engines, Linux players, and systems with better OGG than Opus support. Both are royalty-free open formats from the Ogg ecosystem.
ChangeThisFile converts your Opus to OGG Vorbis using FFmpeg on secure servers. OGG Vorbis has broader legacy compatibility in game engines (Unity, Godot 3) and some Linux audio tools compared to Opus. Both are royalty-free open standards using the Ogg container. Files are auto-deleted after conversion, free with no signup.

Opus vs OGG: Format Comparison
Key differences between the two formats
| Feature | Opus | OGG Vorbis |
|---|---|---|
| Codec Standard | IETF RFC 6716 (2012) | Xiph.Org Vorbis (2000) |
| Quality at Low Bitrate | Superior (better efficiency) | Good (less efficient) |
| Unity Support | Limited | Excellent (native) |
| Godot 3 Support | Limited | Excellent |
| Godot 4 Support | Native | Native |
| Legacy System Support | Newer (limited legacy) | Broader legacy support |
| WebRTC Support | Yes (mandated) | No |
| Container | .opus (Ogg container) | .ogg (Ogg container) |
When to Convert
Common scenarios where this conversion is useful
Unity game engine audio assets
Unity 2022 and earlier has better OGG Vorbis support than Opus for audio assets. Convert Opus audio to OGG Vorbis for reliable import into Unity projects, especially those targeting Unity 2022 or older.
Godot 3 game projects
Godot 3 supports OGG Vorbis natively for audio streams. Convert Opus sound files to OGG for use in Godot 3 projects that haven't yet migrated to Godot 4's expanded codec support.
Legacy Linux audio tool compatibility
Some older Linux media players and audio tools support OGG Vorbis but not Opus. Convert Opus files to OGG Vorbis for use with legacy Linux audio tools and desktop environments.
Open media project contributions
OGG Vorbis is widely recognized as the open-source audio format for projects like Wikipedia's audio files. Convert Opus to OGG Vorbis when contributing to open media projects with OGG requirements.

Frequently Asked Questions
Both are audio codecs from the Xiph.Org / IETF ecosystem stored in Ogg containers. Opus (2012) is the modern successor to Vorbis, with superior efficiency at low bitrates, WebRTC support, and ultra-low latency. OGG Vorbis (2000) has broader legacy compatibility.
Yes. Both Opus and OGG Vorbis are lossy codecs. Transcoding between them introduces generation loss. At high OGG Vorbis quality levels (q6+), the quality remains very good.
Yes. Unity supports OGG Vorbis natively for compressed audio streams. OGG is Unity's recommended format for music and long audio files due to its efficient streaming and broad platform support within Unity.
For legacy game engines and Unity 2022 or earlier, OGG Vorbis has broader support. Modern engines like Godot 4 support both. Opus offers better quality at equivalent bitrates, but OGG has more established game engine integration.
Both .ogg and .opus use the Ogg container. The .opus extension specifically identifies Opus audio content, while .ogg typically contains OGG Vorbis audio. Some older players don't recognize .opus and expect .ogg.
Godot 4 supports both OGG Vorbis and Opus natively. Godot 3 supports OGG Vorbis. If you're using Godot 3 or need maximum compatibility, OGG Vorbis is the safer choice.
Yes. Both Opus and OGG Vorbis use Vorbis comment tags for metadata. This makes the metadata transfer very clean — title, artist, album, track number all transfer directly.
Yes. Files are uploaded over HTTPS, processed by FFmpeg on our server, and automatically deleted after download. We do not retain or access your audio content.
