What WebM to MP3 does
WebM files — screen recordings, browser downloads, web video — often hold audio you want on its own. Upload your WebM file, pick an MP3 bitrate, and download just the soundtrack as a standard MP3. The conversion happens in your browser — your file is never uploaded.
How to use it
- Upload a WebM file.
- Choose a bitrate (128–192 kbps suits most music, 64–96 kbps is fine for speech) and optionally mix down to mono.
- Click Convert to MP3, preview the result, then download it.
Good to know
The audio track is decoded by your browser's built-in decoder, so if your browser can play the file's sound (WebM audio is usually Opus or Vorbis), it can convert it. Long videos are decoded fully in memory, so very large files may be slow on low-memory devices.
Privacy
Decoding and MP3 encoding both run on your device. Nothing is sent to a server.
