What is an Opus file?
Opus audio
Opus is a modern, open audio codec that sounds better than MP3 and AAC at low bitrates, which is why WhatsApp voice messages, Discord, and many video calls use it. An .opus file is an Ogg file with Opus audio inside.
What opens Opus files
Chrome, Firefox, Edge, Android, WhatsApp, VLC, and foobar2000. Many Apple apps, older Windows players, and car stereos can't play it.
FAQ
Questions, answered
Is the Opus converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. Everything runs inside your browser with Mediabunny and your browser's WebCodecs video encoders, so your files never leave your device. Once the page has loaded, it even works offline.
Does it work on iPhone, Android, Mac, and Windows?
Yes. It works in current versions of Chrome, Edge, Safari, and Firefox. Phones handle short clips well, and long or 4K videos convert best on a computer.
