Turn WebM audio into MP3
WebM is common for web and browser recordings, and its audio (usually Opus) is efficient — but not universally supported. Extracting the audio as an MP3 gives you a file that plays on every device, app and media player, ideal for saving music, a podcast-style listen, or a recording you captured in the browser.
Mynify extracts the audio entirely in your browser, with nothing uploaded — a real difference from converter sites that send your whole file to a server first.
How it works
- Drop your WebM.
- Mynify loads its engine once (~30MB, cached afterwards), then extracts the audio at 192 kbps.
- Download the MP3.
Free, unlimited, no signup, no watermark — your file never leaves your device.
