Frequently Asked Questions
Where do Opus files come from?
Opus is the voice codec of the modern internet: WhatsApp and Telegram voice notes, Discord and Zoom recordings, and most WebRTC calls. It's excellent for speech but poorly supported by players and editors — hence the need to convert.
Is this safe for private voice messages?
Yes — that's the point of this tool. A voice note is about as personal as a file gets, and traditional converters upload it to their servers. Here the conversion runs in your browser and the audio never leaves your device.
Is it safe to convert voice recordings online?
Yes. Unlike traditional online converters, this tool never uploads your files. The conversion runs entirely inside your browser using WebAssembly, so voice recordings never leave your device — you can even disconnect from the internet after the page loads and it still works.
Is this converter really free?
Yes — completely free, with no sign-up, no watermarks, and no file-per-day limits. Because conversion happens on your own device, there are no server costs to pass on to you.
