Why extract audio
Pulling just the audio out of a video is useful for saving a podcast or lecture recording, turning a music video into an MP3, or grabbing a voice memo without keeping the much larger video file around.
Good to know
Extraction runs on the same browser-based FFmpeg engine as the Audio Converter, loading once per session and staying cached afterward. The video stream is dropped entirely — only the audio track is kept and re-encoded to the format you chose.
Extract Audio from Video FAQ
Is my video uploaded anywhere?
No. Your file is processed entirely in your browser — nothing is sent to a server.
Which video formats can I use?
MP4, MOV, MKV, AVI, WEBM, M4V, FLV, MPEG, MPG, TS, and 3GP.
Does extracting re-encode the audio?
Yes — the audio track is re-encoded to whichever format you pick, at a high bitrate. The video stream itself is simply dropped, not re-encoded.
Why does the first extraction take longer?
The first time you extract audio, your browser downloads a one-time conversion engine (a build of FFmpeg compiled for the browser). It's cached after that, so every extraction afterward in the same session starts instantly.
What if my video doesn't have an audio track?
You'll get a clear message explaining there's no audio track to extract, instead of a broken file.
Is it free?
Yes, extracting audio with this tool is free.
