WebM to MP3 Converter
Runs in your browser — your files are never uploaded.
Pull the audio out of a WebM file and save it as MP3. WebM downloaded from the web frequently holds Opus or Vorbis audio, which most players and car stereos will not touch — MP3 goes everywhere. Audio-only WebM files, which some sites serve for streams, work here too.

Frequently asked questions
Does this keep the video?+
No — this extracts the audio track only and discards the picture. That is the point: the result is an audio file you can play anywhere.
Will converting Opus to MP3 lose quality?+
Slightly, since both are lossy and re-encoding compounds their losses. It is not usually audible at the default bitrate. There is no way to avoid it — the formats are not compatible, so the audio has to be decoded and re-encoded.
My WebM has no audio track.+
Then there is nothing to extract, and the conversion fails. Some WebM files are video-only by design, particularly the separate streams sites use for adaptive playback.
