Where your WebM came from
WebM is what a browser writes when it records, and what a lot of the web serves. Inside is usually Opus or Vorbis audio.

Why you are converting it
Almost everything outside a browser. A WebM is excellent on a page and unwelcome on a desktop, in a car, or in anything with a timeline. MP3 is the format nothing refuses. That is its entire remaining argument and it is a good one.

What it costs
MP3 is lossy, so a little goes at any bitrate. 192 kbps is transparent for speech and close to it for music; 320 is the ceiling and is only worth it when the source was better than the target.
