The formats

OGG and Opus at a glance

  • What is an OGG file?

    OGG is an open audio container that usually holds Vorbis or Opus audio. It sounds better than MP3 at the same size and is common in games, Linux apps, and Android notification sounds. Apple's apps have limited support for it. It opens in Chrome, Firefox, Edge, Android, VLC, Audacity, and most game engines. Many Apple apps and car stereos can't play it.

  • What is an Opus file?

    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. It opens in 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 this OGG to 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. The conversion 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 converting OGG to Opus lose quality?

Opus is a lossy format, so the audio is compressed. At the default bitrate most people can't hear a difference. Choose 256 or 320 kbps for music you care about.

Can I convert several OGG files at once?

Yes. Add as many as you like. They're converted one after another, and you can download each Opus file as soon as it's ready or all of them in one ZIP file.

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.

What can open an Opus file?

Chrome, Firefox, Edge, Android, WhatsApp, VLC, and foobar2000. Many Apple apps, older Windows players, and car stereos can't play it.

Is there a file size limit?

There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and a computer can usually handle recordings several hours long.
