How it works
- Drop the video.
- Choose the audio format and bitrate.
- Start, then download the audio file.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see are the tool’s own code and, once cached, none at all.
Frequently asked questions
Which format should I choose?
MP3 at 192 kbps for anything that will be listened to. WAV if it is going into editing software and you want no further loss. FLAC to archive it losslessly at about half the size of WAV.
Can I extract the audio without re-encoding it?
Not in this tool: the audio is decoded and re-encoded to the format you pick. For speech at 192 kbps the extra generation is inaudible.
Is my video uploaded?
No. FFmpeg itself is compiled to WebAssembly and runs inside this tab; the file is read from disk into memory and the result is written back out. Nothing is transmitted, which is why a two-hour film will not work here — your device is doing all of it.
