Convert WEBM to MP3 online
Convert a WEBM file to MP3 directly in your browser — the file is never uploaded to a server.
or click to select it
Extract the audio from a WEBM video — the web's native container, produced by browser screen recorders, downloaded clips and Discord recordings — and save it as an MP3 that any player, app or car stereo can open.
WEBM is an open, royalty-free container built for the web — it's what you get from most browser-based screen recorders, and it's a common format for clips saved from streaming sites or shared in Discord. The tool strips out the video stream and re-encodes the audio track as MP3.
Use cases
- Turn a browser screen recording into an MP3 to keep just the narration.
- Convert a WEBM clip saved from Discord or a streaming site into audio you can play anywhere.
- Get the soundtrack out of a WEBM video without needing a video-capable app.
How it works
- 1
Upload your WEBM file
Drop in a screen recording, downloaded clip or any other WEBM video.
- 2
Adjust the bitrate if you want
A high automatic quality is used by default; set a specific bitrate in the options if you need a smaller file.
- 3
Download the MP3
Once it's done, download the resulting audio file.
Technical details
Runs ffmpeg.wasm in your browser. WEBM almost always carries its audio as Opus (occasionally the older Vorbis) — a codec built for the web that's more efficient than MP3 at the same bitrate, but far less universally supported. Converting to MP3 trades some of that efficiency for playback compatibility with essentially any device.
Frequently asked questions
Why do screen recordings so often end up as WEBM?
Most browsers can record and encode WEBM natively without extra software, which is why built-in screen recorders and many browser extensions default to it.
Is there a file size limit?
Videos up to 300 MB work reliably on most devices; larger files may exhaust the browser's available memory.
