Built for voice notes
Discord, WhatsApp, Telegram and many web apps record in OPUS. Turn those .opus files into MP3s that open in any player, on any phone or computer.
Plays everywhere
MP3 is the most universally supported audio format — car stereos, old phones, editing software and messaging apps all accept it where OPUS often won't.
Private & secure
Audio is uploaded over HTTPS, processed in the EU, never shared, and permanently deleted within 1 hour. Nothing is used for AI training.

Common questions

How do I get the .opus file from a voice message?

On WhatsApp, open the chat, tap the voice message's menu and choose "Share" or "Save" — the file is usually an .opus (or .ogg) you can upload here. On Discord, right-click the voice message and "Save"; desktop exports come as .opus. Then drop it into the converter above.

Will the audio quality drop?

We export MP3 at a high bitrate, so for speech and voice notes the difference is inaudible. Both OPUS and MP3 are lossy formats, so re-encoding can't add detail — but it won't noticeably degrade a voice recording either.

What's the difference between OPUS and OGG?

OPUS is an audio codec that's usually carried inside an Ogg container, which is why some files are labelled .ogg and some .opus. Our converter accepts both — just upload whatever you have and pick MP3.

Is there a file size limit?

Free users can convert files up to 25 MB without an account, or up to 10 conversions per day with a free account — more than enough for voice notes. Pro users get 500 MB per file, with higher limits on Business and Enterprise.
