    WAV for editing, M4A for a small file that plays everywhere, OGG for web projects.

    The audio track is saved on your device in seconds. Extract from as many videos as you want.

Frequently asked questions

What audio formats can I get?
WAV, M4A, or OGG. Browsers cannot encode MP3, so this tool does not offer it. M4A plays everywhere MP3 does, including phones, editors, and every social platform.
Does extracting change the audio quality?
WAV keeps the full decoded signal with no compression. M4A and OGG re-encode the audio, and for most recordings the difference is not audible.
What video formats can I upload?
MP4, MOV, WebM, and MKV. The video track is discarded and only the audio is kept.
Does my video get uploaded anywhere?
No. The audio is extracted entirely in your browser. Nothing leaves your computer.
Is this really free?
Yes. No signup, no watermarks, no limits. Use it as much as you want.
