WebM is a video format built for the web. Browser-based screen and meeting recorders, and many online tools, save recordings as .webm. The sound inside is typically Opus or Vorbis, which plenty of editors and phones can't open on its own.
Extracting the audio gives you a normal MP3 or WAV you can edit, share or transcribe. Recordings made in a browser often have a little background noise — run the result through noise reduction if needed.
