Convert WebM to MP3

WebM audio is usually Opus, so this genuinely re-encodes rather than repackages. MP3 is the target when the result needs to play on something that has never heard of Opus.

What is WebM?

Google's royalty-free video container, built for the web and carrying VP8, VP9 or AV1 video with Opus audio. Every modern browser plays it without a plugin or a licence, which is why it's the sensible choice for video you host yourself and a poor one for video you send to someone's phone.

What is MP3?

The format that made digital music portable, and thirty years on it's still the safest bet that a file will simply play - any device, any car, any decade-old bit of hardware. It's lossy, its patents expired in 2017, and no browser has ever been able to write one, which is why encoding it here needs LAME.
