About WebM to MP3
Screen recorders, browser-based tools and many websites save recordings as WebM. Some phones, cars and audio apps can't play them. MP3 works almost everywhere.
The WebM's sound, usually Opus or Vorbis, is decoded by your browser and encoded to MP3 on your device. Your recording isn't uploaded.
Pick the quality: 128 kbps is enough for speech and screen recordings with narration, 192 kbps suits most music, and 320 kbps is the best MP3 can do. Because the WebM's sound is already compressed, converting it again loses a little detail, which you won't usually hear at 192 kbps or more.
WebM files with sound only, such as recordings from web-based voice tools, work too. You can convert several files at once and download them together as a ZIP. If you want to keep the picture, use WebM to MP4 instead.
The MP3 lasts exactly as long as the recording. If the WebM has no sound at all, for example a silent screen capture, you get a clear message rather than a silent MP3.

Yes. Audio-only WebM files, such as browser voice recordings, convert the same way.

Yes, with WebM to MP4, which keeps both picture and sound.
