About the WAV to Opus Converter
This WAV to Opus converter turns audio files from WAV into Opus without installing software or uploading anything. It solves a common problem: WAV files are huge, around 10 MB per minute of audio. Converting to Opus gives you tiny, great-sounding Opus audio, ideal 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 WAV to Opus Converter
- Click "Choose files" or drag your WAV audio files onto the box. You can add several at once.
- Choose the Opus bitrate: 128 kbps for speech, 192 kbps for music or 320 kbps for the best quality.
- Press "Convert to Opus". The conversion runs on your device and shows its progress.
- Download each Opus file, or use "Download all (ZIP)" when you converted several.
- Open the result in WhatsApp or Telegram to check it; your original WAV is never changed.
Tips & benchmarks
- Opus sounds great at low bitrates: 64 kbps for speech and 128 kbps for music.
- WAV is lossless and Opus is not, so keep your original WAV as the master copy and use the Opus for sharing.
- As a guide, one minute of audio at 128 kbps is about 1 MB, and at 320 kbps about 2.4 MB.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the Opus to a website or government portal.
