Extract Audio from a Video
Pick a video, choose MP3 or WAV — the audio track is extracted in your browser, nothing is uploaded.
Extract audio from a video in your browser
Pick a video, choose MP3 or WAV, and get just the audio track — no video. The extraction runs entirely in your browser with ffmpeg compiled to WebAssembly, so your video is never uploaded to a server.
Formats
- MP3 — lossy, small, and playable everywhere (libmp3lame). Pick a bitrate from 32 to 320 kbps; 192 kbps (the default) is a good balance of size and quality.
- WAV — lossless 16-bit PCM. Larger files, but a perfect copy of the decoded audio — ideal for editing or archiving. (The bitrate field is ignored for WAV.)
Tips
- Leave the format blank to default to MP3 at 192 kbps.
- The output keeps the original filename with the new audio extension.
- Works offline once the page has loaded — nothing leaves your device.
FAQ
Which video files can I extract audio from?
Anything the bundled ffmpeg build can decode — MP4, MOV, WebM, MKV, AVI, and most
other common containers. The video stream is simply dropped (-vn) and the audio
track is re-encoded to your chosen output format.
Should I choose MP3 or WAV?
MP3 (the default) is lossy but small and plays everywhere; pick a bitrate between 32 and 320 kbps — 192 kbps is a good balance. WAV is lossless 16-bit PCM: much larger, but a perfect copy of the decoded audio, which is what you want before editing in a DAW. The bitrate setting is ignored for WAV.
What if I enter a bitrate like 500 kbps?
Bitrates outside the libmp3lame-supported 32–320 kbps range are rejected with a clear error rather than silently changed, so the file you get always matches the settings you asked for.
Is my video uploaded to a server?
No. The extraction runs in your browser with ffmpeg compiled to WebAssembly. The video never leaves your device, and once the page has loaded the tool even works offline.
