Video to Audio
Extract the audio track from a video file as a WAV or MP3.
How to use this tool
- Drop a video file.
- Choose WAV or MP3 output (and MP3 bitrate).
- Extract and download.
How it works
An OfflineAudioContext decodes the file's audio track; PCM samples are written to WAV or fed through lamejs for MP3.
Tips
- WAV for editing (lossless), MP3 at 192 kbps for sharing.
- MP4 with AAC audio converts fastest on most browsers.
Limitations
Browser codec support limits which videos can be decoded; DRM-protected content won't work.
Frequently asked questions
How does extraction work?
The video demuxes in the browser and its audio samples are decoded and exported as WAV, or encoded to MP3 with lamejs.
Is it true MP3?
Yes — MP3 output is encoded on-device; WAV is lossless if you prefer maximum quality.
Do container formats matter?
MP4, WebM and MOV files play if your browser supports the codec — which most modern browsers do.
