About the OGG to Opus Converter
Convert OGG to Opus online for free, with no account and no watermark. IPhones and many car stereos do not play OGG, so switching to Opus is the quickest way to get tiny, great-sounding Opus audio for voice notes, podcasts, VoIP and the smallest good-sounding audio files.
Audio and video are processed by FFmpeg compiled to WebAssembly, the same open-source engine behind VLC and HandBrake, running inside your browser tab. Because everything happens on your own device, your audio files are never uploaded, stored or seen by anyone else, which makes it safe for voice recordings, interviews and unreleased music.
What to expect: the sample rate and channels are kept, and you can pick the bitrate; the processing engine (about 30 MB) is downloaded once and then cached by your browser.
How to use the OGG to Opus Converter
- Click "Choose files" or drag your OGG audio files onto the box. You can add several at once.

- Press "Convert to Opus". The conversion runs on your device and shows its progress.
