Convert WebM to MP3.
Pull the soundtrack out of a WebM video, such as a browser screen recording, as an MP3 that plays anywhere.
From a recording to a podcast file
Recorded a call, a lecture or a talk in the browser? The MP3 is the part you can listen to on a commute or send for transcription.
Quality
The MP3 is encoded at 128 kbps at the original sample rate, usually 48 kHz for WebM. That is clear for speech and fine for music.
Size change
At 128 kbps the MP3 takes about 1 MB a minute.

Common questions
Is it free?+
Yes. Convert WebM to MP3 free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Your file is uploaded to a private bucket, converted on our own engine, and auto-deleted after 1 hour. It is never sent to a third-party converter.
Where do WebM files come from?+
Browser screen recorders, web meeting tools and many sites save video as WebM. The audio inside is usually Opus, which many players, car stereos and editors cannot open. MP3 they all can.
Is the video kept?+
No. Only the audio goes into the MP3. To keep the picture, use WebM to MP4.
