Extract audio from video without changing it
Extract the audio track from a video and save it as a standalone file. If the video has several language tracks, choose which one you want.
This keeps the sound exactly as it was recorded — same format, nothing re-encoded. If what you need is an MP3 you can play on anything, use the Video to MP3 tool instead.
How it works
Choose your media file
Any video or audio file is opened locally.
Pick the track
If several audio tracks exist, you choose which one to keep.
Choose an output format
MP3 for sharing, WAV or FLAC for editing.
The track is opened, not sent
Editing audio normally means uploading the file and hoping the service is trustworthy. Here your browser opens the track from your disk, works on it in place, and saves the result back. The audio never crosses the network.
- Opened from your disk by your browser — not sent anywhere first.
- Held in the tab while the tool works, then dropped.
- Saved to your device by your browser, not by a link to a server.
- Closing the tab clears the working copy completely.
- No account, so nothing is ever attached to an identity.
- No tracking of what you worked on or what was inside the file.
There is no queue, no render farm and no waiting room. The track is worked on in front of you and released the moment the tab closes. The how it works page covers what actually happens inside the tab, and our DevTools guide shows how to confirm 0 bytes are uploaded.
What people use it for
Keeping the sound, dropping the picture
Interviews and lectures are often recorded as video. Keeping just the audio makes the file far smaller.
Sending a voice note that is too long
A ten-minute recording is a lot to ask someone to play. Trim it to the useful minute and it actually gets heard.
Fitting an episode inside a feed limit
Podcast hosts set a maximum size. Checking the result here saves a failed upload later.
Keeping a copy that will still open in ten years
A widely supported format is a safer long-term bet than a container only one app understands.

When something goes wrong
Corrupt files, and formats outside the list above, stop with a plain message rather than a spinner that never finishes. If a track plays in your music app it will normally open here.
The audio container is not one the browser can read. Convert it to MP3 or WAV first, then run it through again.
Why not an upload site
An upload-based audio editor sends your recording to a server and sends the result back. Removing that round trip removes the waiting, the caps and the copy of your file.

Questions
Can I extract audio from a file with several language tracks?
Yes. If more than one audio track is found, a list appears and you can pick the one you want before extracting.
Is the extracted audio identical to the original?
When the source audio is already in a compatible format, it can be copied without re-encoding, so it is identical. Otherwise it is re-encoded into your chosen format.
Why does my extracted file sound quieter than expected?
Some videos store multi-channel audio such as 5.1. When that is reduced to stereo, the overall level can drop. Choosing a higher bitrate helps preserve the detail.
Is there a file size limit?
No fixed limit is imposed by the tool. The practical ceiling is how much memory your device has free, because the whole job runs inside this browser tab.
Does it work without an internet connection?
Yes, once the page has loaded. Nothing is fetched while you work, so a dropped connection does not interrupt a run.
Do I need an account or an email address?
No. There is nothing to sign up for, and nothing is ever attached to an identity because no file leaves your device.
