Extract Audio from Video — Free MP4 to Audio Tool
Need just the sound from a video — a lecture’s narration, a song from a clip, interview audio for editing? This tool decodes the audio track locally and hands you an audio file. No upload, no waiting on a server, no sketchy converter sites.
Extract Audio from Video
Pull the soundtrack out of any video — save it as WAV or WebM audio, instantly.

3 Extract & download
✅ Done — your audio file
ℹ️ Honest note: browsers can decode most common audio, but a few exotic codecs won't decode — if that happens you'll get a clear message, not a broken file.
How it works
- Drop in a video — only the audio track is read, nothing is uploaded.
- Choose WAV for full uncompressed quality or WebM audio for a much smaller file, plus stereo or mono.
- Hit Extract Audio: the tool decodes the soundtrack locally and gives you a downloadable audio file in seconds.
Your files never leave your browser — extraction happens entirely on your device.
Everyday uses
- Students — pull lecture audio to listen to on the go without the video.
- Editors — grab interview or podcast audio from a video file for editing.
- Musicians — isolate a song or riff from a video clip for practice.
- Creators — reuse a video’s narration as a voiceover track elsewhere.
- Note-takers — extract meeting audio to transcribe or archive.
Rule of thumb: WAV is the safe choice for editing (every editor opens it); WebM audio is the smart choice for sharing and archiving. Use mono for speech — you won’t hear the difference, but the file will be half the size.
