Convert Opus to MP3

Opus is what voice notes and calls are recorded in — WhatsApp, Telegram, Discord — but a .opus file will not open in a lot of everyday players. This re-encodes Opus to MP3 with WebCodecs in your browser, so a voice note becomes a file that plays anywhere, without ever being uploaded.

Runs entirely in your browser — your file is never uploaded.

Frequently asked questions

Can I convert a WhatsApp or Telegram voice note?

Yes — save the voice note as .opus (or .ogg) and drop it in. It is re-encoded to MP3 on your device, ready to play or share anywhere MP3 is accepted.

Is the file uploaded?

No. The conversion runs with WebCodecs in your browser, so the audio never leaves your device — no account, no quota, no size limit. Chrome, Edge and Firefox work best.
