About this option

Sometimes you want only the sound of a video: a lecture, a podcast recorded on camera, a song from a concert clip. This page opens the converter on MP3 and accepts video files, discarding the picture and keeping the audio track.

  • Saving the audio of a recorded lecture or interview
  • Making a podcast from a video recording
  • Getting a song or voice track from a clip you own

How to use it

  1. 1Drop your MP4, MOV, WebM or other video file
  2. 2Keep MP3 selected and click Convert
  3. 3Download the audio-only MP3

Frequently asked questions

Is the video uploaded?

No. The video stays on your device and only the audio is extracted by your browser.

Which video formats work?

Most common ones, including MP4, MOV, WebM and MKV, as long as your browser can read the file.

Why does a big video take longer?

The whole file has to be read before the audio can be extracted, and browser-based conversion is slower than desktop software for very large files.
