The audio inside a video file is already a complete, finished recording — an interview, a lecture, a song, a podcast take. Pulling it out is not a conversion so much as a separation, and it does not require the video to be decoded at all.

What Extract Audio does

Discards the video stream and writes the audio to its own file. MP3 uses LAME at quality level 2, a variable bitrate that averages roughly 190 kbps — transparent for speech and close to it for music, at about a tenth of the size of the lossless option.

WAV writes uncompressed 16-bit PCM. Nothing is thrown away, which matters if the audio is going into an editor for further work, but the file is large: roughly 10 MB per minute of stereo.

Detailed steps

  1. Drop the video in.
  2. Choose MP3 for listening, sharing or transcription; WAV if the audio is going into an editor.
  3. Extract, then download.

Worth knowing

Choose WAV whenever the audio has more work ahead of it — noise reduction, levelling, mixing. Every MP3 encode is lossy, so editing an MP3 and re-saving it applies that loss twice. If the file is only ever going to be listened to, MP3 is the sensible default and a tenth of the size.

Frequently Asked Questions

Which should I pick, MP3 or WAV?

MP3 for anything you will listen to, upload or send — at quality 2 most people cannot distinguish it from the source. WAV if it is going into audio software, because further editing compounds the loss from a lossy format.

Is the MP3 a fixed bitrate?

No. It uses variable bitrate at quality level 2, which spends more data on complex passages and less on quiet ones. That gives better quality per megabyte than a fixed rate, so the average lands near 190 kbps rather than being pinned there.

Can this be better than the original audio?

No, and nothing can. If the video already contained a heavily compressed 64 kbps track, extracting it to WAV produces a large file that sounds exactly like a 64 kbps track. Extraction preserves; it cannot restore.

Why is this fast when compressing a video is slow?

The video is never decoded — it is discarded with a single flag. Only the audio is processed, and audio is a fraction of the data in a video file.

Is Extract Audio free?

Yes. The Vootkit free plan includes 5 tool runs a day. Upgrade to Vootkit Pro for unlimited daily use, an ad-free workspace and saved workflows.

Are my files uploaded?

No. Extract Audio runs entirely in your browser — your file is processed on your own device and never sent to a server. There is nothing for us to store or delete.

Do I need to install anything?

No. Extract Audio works in any modern browser on desktop, tablet or phone. Open the page and start.

How often can I use it? Is there a daily limit?

On the free plan you get 5 tool runs a day. When you reach the limit you'll see a prompt to upgrade, and it resets the next day. Vootkit Pro removes the cap entirely for unlimited daily use.

Your video is processed entirely in your browser. The video engine downloads once from a CDN the first time you run a tool, then works from cache. Large files are memory-bound, so keep clips reasonable.
