Convert OGG to Opus Online Free
Convert OGG Vorbis audio to Opus — the modern successor that outperforms Vorbis at low bitrates. Both use the Ogg container, but Opus delivers superior efficiency for streaming and communication.
ChangeThisFile converts your OGG Vorbis to Opus using FFmpeg on secure servers. Opus is the modern evolution of the Ogg ecosystem from Xiph.Org, delivering superior quality at lower bitrates than OGG Vorbis and adding support for real-time voice. Both are royalty-free open standards. Files are auto-deleted after conversion, free with no signup.

When to Convert
Common scenarios where this conversion is useful
Upgrading legacy OGG Vorbis libraries to modern Opus
Convert older OGG Vorbis music libraries to Opus for better streaming efficiency. At equivalent quality, Opus files are typically 30-50% smaller than OGG Vorbis, reducing storage and bandwidth.
Web audio streaming optimization
Convert OGG Vorbis tracks to Opus for web streaming. Opus has better browser support (including Safari 14.1+) and lower bitrate requirements, improving web audio performance.
Discord and WebRTC audio integration
WebRTC and Discord use Opus exclusively. Convert OGG Vorbis audio files and sound effects to Opus for use in WebRTC applications and Discord bots.
Game engine modernization
Newer game engines (Godot 4, modern Unity) are adding Opus support alongside OGG Vorbis. Convert OGG assets to Opus for games targeting smaller asset sizes and better streaming performance.
How to Convert OGG to Opus
-
1
Upload your OGG file
Click the upload area or drag and drop your OGG Vorbis file. Files up to 50MB are supported and transferred over HTTPS encryption.
-
2
Convert to Opus
Click Convert. FFmpeg decodes the OGG Vorbis audio and re-encodes it using the libopus encoder, producing a modern Opus audio file in an Ogg container.

3
Download your Opus file
Download the Opus file. It will typically be smaller than the OGG source at comparable quality. The file is auto-deleted from our servers after download.
Frequently Asked Questions
Yes, in most technical metrics. Opus delivers better audio quality than OGG Vorbis at equivalent bitrates, especially at low bitrates (below 96 kbps). Opus also supports speech, has lower latency, and has better browser/platform support.
Yes. Both OGG Vorbis and Opus are fully open and royalty-free standards. Opus is standardized by the IETF (RFC 6716) while OGG Vorbis is from the Xiph.Org Foundation. Either can be used commercially without licensing fees.
Yes. OGG Vorbis is a lossy codec, and Opus is also lossy. Transcoding between them involves generation loss. At high Opus bitrates (128+ kbps), the quality remains very good.
Not natively in the Music app. iOS Safari (14.1+) supports Opus in web pages. For file playback, you need VLC for iOS. For Apple device library compatibility, AAC or MP3 are better choices.
Godot 4 added native Opus support. Unity supports Opus in some configurations. OGG Vorbis still has broader legacy support in game engines, but Opus adoption is growing for newer projects.
Both .ogg and .opus use the Ogg container format. The .ogg extension typically contains OGG Vorbis audio. The .opus extension specifically indicates Opus audio in an Ogg container. Some players differentiate them; using the correct extension matters.
Yes. Chrome, Firefox, Edge, and Opera support Opus natively. Safari added Opus support in Safari 14.1 (2021). Modern Opus support is nearly universal across desktop browsers.
Yes. Files are uploaded over HTTPS, processed by FFmpeg on our server, and automatically deleted after download. We do not retain or share your audio files.
