WEBM to MP3

Pull the audio track out of a WEBM video and save it as MP3. MP3 is the safe default: every player built in the last 25 years reads it. WebM carries Opus or Vorbis, neither of which older players reliably handle, which is usually the whole reason for pulling the audio into something else. Runs on your own Vistalyth Tools instance. Files never reach a third party.

Features

  • Audio extracted directly, with no needless video decode
  • Bitrate selectable, so you set the size-versus-fidelity point
  • Track selection on WEBM files carrying more than one audio stream
  • Your WEBM files are processed on your own server and never uploaded anywhere

What you can do

  • Get a podcast or interview out of a recorded WEBM for offline listening
  • Lift music or a voiceover from WEBM footage for reuse
  • Feed the audio to transcription or analysis that will not take video

Self-hosted. Your files never leave your network.

Vistalyth Tools runs entirely on your own infrastructure. Files processed with WEBM to MP3 are never uploaded to third-party servers. Deploy a single Docker container and process files with full privacy, no watermarks, and no usage limits. Open source under AGPL-3.0.

Frequently asked questions

Does extracting audio re-encode it?
Yes, unless the source track is already MP3, in which case it is copied out untouched. Going from one lossy format to another loses a little, so pick the highest bitrate you are willing to store.
My WEBM has several audio tracks. Which one do I get?
The default track unless you choose another. Multi-track files list what they contain so you can pick.
Why pick MP3 here?
Choose MP3 when the file has to simply work somewhere you do not control.
How big will the MP3 be?
Roughly bitrate times duration. At 192kbps that works out around 1.4MB per minute.
