About this converter

WebM is the web's open video format, and its audio is usually stored as Opus or Vorbis. WebM to MP3 extracts that audio and re-encodes it to MP3 - the format that plays on every phone, car stereo, and music app.

It is handy for saving the audio from screen recordings, web clips, and other WebM files as a portable sound file. The video is discarded; only the audio remains.
