Summary
Try browser-native WAV-to-Opus encoding, check your browser's support, and get a ready-to-run FFmpeg command as a reliable fallback.
How it works
- Drop or select a WAV file — the tool inspects its sample rate, channels, and duration instantly.
- Your browser is tested for MediaRecorder Opus support (audio/ogg; codecs=opus or audio/webm; codecs=opus).
- If your browser supports Opus encoding, the WAV is decoded with the Web Audio API and re-encoded live.
- Download the resulting Opus file with one click.
- If your browser does not support Opus encoding, a detailed explanation is shown along with a ready-to-copy FFmpeg command that will do the conversion offline.
- The FFmpeg command generator lets you customize bitrate and output container regardless of browser support.
Use cases
- Compress large WAV recordings for web streaming or podcast distribution.
- Prepare audio assets for WebRTC applications that require the Opus codec.
- Reduce voice memo file sizes without audible quality loss.
- Generate Opus audio tracks for HTML5 video in WebM containers.
- Convert game sound effects from WAV to Opus for smaller download bundles.
- Archive spoken-word recordings at low bitrates with excellent intelligibility.
- Encode audio for Discord bots, which use Opus natively.
- Batch-convert WAV files using the generated FFmpeg commands in a shell script.
