About WebM files
Any WebM, with a picture or without one, converts to MP3 with Audo: up to 10 GB with no account, and up to 10 hours signed in, and the first hour of each file is free, 10 times a day. A 3-minute recording usually takes about 4 seconds.
WebM is an open format for the web, backed by Google. Its picture is VP8, VP9, or AV1, and its sound is Opus or Vorbis. Browsers such as Chrome and Firefox save recordings made on web pages as WebM: screen recordings, webcam clips, and voice notes from sites that record in the browser.
Many phones, editors, and players can't open WebM, while an MP3 plays almost anywhere. The MP3 keeps about the same bitrate as the WebM's sound, never less than 64 kbps. This page gives you the sound, not an MP4 video. If the recording is noisy, Remove noise and Audio enhancer take the WebM as it is.
Questions
Does a WebM video have sound?
Usually: a WebM's sound is Opus or Vorbis, and either converts here. A WebM can also hold sound with no picture, as voice recordings made in a browser do, and that works too. One with no sound at all has nothing to convert.
How do I extract the audio from a WebM?
Add the WebM at the top of this page and download the MP3: the picture is left out, and only the sound comes back. For WAV, M4A, FLAC, OGG, or Opus instead, pick it under Convert to.
Can I keep the sound exactly?
When the WebM's sound is Opus, pick Opus under Convert to: the sound is copied as it is, not converted again.
Is anything lost?
Opus to MP3 is one lossy format to another, so a little detail goes. Most people hear no difference. WAV or FLAC lose nothing more, but they're bigger.
Can I convert a YouTube video to MP3?
Yes, if it's your own: download it from YouTube Studio, then add the file here. Audo can't open a YouTube link.
Why is my screen recording a WebM?
Browsers such as Chrome and Firefox save recordings made on a web page as WebM, so a screen recorder that runs in the browser hands you a WebM.
Is it free?
Yes. Audo is free for the first hour of each file, 10 times a day, with no sign-up. Whole files are $0.01 a minute ($0.60 an hour), with no subscription — see pricing.
What happens to my files?
They stay private. Files are deleted after 24 hours, and free results after 1 hour.
