What is Opus?
Modern open-source codec. Best quality-per-bit of any lossy format. Used by Discord, WebRTC, and modern browsers.
What is OGG?
Open-source compressed format. Better quality than MP3 at similar bitrates. Used in gaming and web applications.
Why Convert Opus to OGG?
Opus is a superb modern codec — it's what Discord, WhatsApp voice notes, and WebRTC use because it delivers great quality at low bitrates. But it's relatively new, and plenty of software still doesn't accept it. That's where OGG Vorbis comes in: it's the older, extremely well-established open format that game engines like Unity and Godot, many indie audio middleware tools, older media players, and a lot of Linux software support out of the box, often preferring it over Opus. If you have an Opus file — a voice message you saved, audio you exported, a clip you downloaded — and something won't take it, converting to OGG Vorbis usually solves the problem while staying in the open, royalty-free family of formats. This is a lossy-to-lossy conversion: Opus and Vorbis are both compressed, so you're not restoring detail, just moving into the container and codec the target actually supports. For game audio especially, OGG Vorbis is a safe default — it loops cleanly, streams well, and is a first-class citizen in most engines. This converter decodes the Opus and re-encodes to OGG Vorbis with FFmpeg compiled to WebAssembly, entirely inside your browser, so your file is never uploaded to a server. Keep the original Opus if the destination supports it — reach for OGG when compatibility is the goal.
Who Uses This Converter
Game audio for Unity & Godot
OGG Vorbis is natively supported in most game engines. Convert Opus clips so they import and loop cleanly.
Play Opus on older software
Media players and tools that don't support Opus usually handle OGG Vorbis. Convert for broad compatibility.
Save voice notes in an open format
Turn saved Opus voice messages into OGG Vorbis for players that accept it, staying royalty-free throughout.
Linux and open-source workflows
OGG Vorbis is a first-class citizen across Linux audio software. Convert Opus files to fit those pipelines.
Frequently Asked Questions
How do I convert Opus to OGG?
Drop your .opus file into the converter above and download the OGG (Vorbis) file it produces. Everything runs in your browser — no upload, no signup, nothing sent to a server.
Is OGG the same as Opus?
Not quite. Both are open formats, but this converter produces OGG Vorbis — the older, very widely supported codec. Opus is newer and more efficient but not accepted everywhere, which is why converting to OGG Vorbis improves compatibility.
Why convert Opus to OGG for game development?
Game engines like Unity and Godot, and much audio middleware, support OGG Vorbis natively and sometimes don't accept Opus. Converting to OGG Vorbis gives you an engine-friendly file that loops and streams well.
Will I lose quality converting Opus to OGG?
Both Opus and Vorbis are lossy, so this is a lossy-to-lossy conversion — it won't restore detail, and there's a small generational loss inherent in re-encoding. At a good bitrate the difference is inaudible for most listening.
Is my file uploaded when converting?
No. Conversion runs entirely in your browser using FFmpeg WebAssembly, so your Opus file never leaves your device.
Is this Opus to OGG converter free?
Yes. Free users get 5 conversions per month. The output is limited to the first 10 seconds as a preview, with a 20MB input file size limit. Upgrade to Pro for unlimited, full-length conversions.
