Turn WhatsApp voice notes and any .opus / .ogg recording into MP3 files that play everywhere.

About this OPUS to MP3 converter

WhatsApp, Telegram and other messengers send voice notes in the OPUS codec — usually wrapped in a .ogg or .opus container. OPUS is excellent quality at small sizes, but MP3 is what every other app expects when you want to share, edit or back up the recording.

This page converts any OPUS or OGG/OPUS file to MP3. Drop in the voice note saved from WhatsApp Web (or copied from your phone), pick the bitrate, and download the MP3.

OPUS to MP3 FAQ

Where do I find my WhatsApp voice notes?

On Android: /WhatsApp/Media/WhatsApp Voice Notes/ in your file manager. On iPhone: forward the message to email or save it via the share sheet, then drop the saved file here.

Will the audio quality drop?

OPUS is already a lossy codec — converting to MP3 is lossy-to-lossy, so there's a tiny generational loss. At 192k it's inaudible for voice notes.

Can I convert multiple files at once?

One at a time on this page — but it's fast. For batch jobs we'd need a Pro tier; let us know if you want one.

Is my file kept private?

Yes. We don't analyse or index your voice note.
