Convert OGG to MP3
Turn OGG and Opus files into MP3s that play everywhere.

Runs in your browser. Nothing is uploaded.
OGG files turn up from messaging apps, game assets, open-source music and anything recorded in a browser — WhatsApp voice notes are Opus in an OGG container. The audio inside is usually excellent and the format is usually the problem: plenty of players and upload forms have never heard of it.
MP3 is the answer to that, and only to that. Opus at a given size beats MP3 comfortably, so this conversion trades quality for compatibility rather than gaining anything. Keep the quality high, since a second lossy pass over already-compressed audio is where artefacts show up.
Both Vorbis and Opus are read, which covers essentially every OGG in circulation. Decoding is the browser’s own, encoding is LAME on your machine, and nothing is sent anywhere — which matters more than usual for voice notes.

Questions
What is inside an OGG file?
Usually Opus these days, sometimes Vorbis. Both are read here, and both convert the same way.
Are WhatsApp voice notes OGG?
Yes, Opus in an OGG container. They convert fine, and nothing is uploaded in the process.
Is MP3 better than Opus?
No, the opposite — Opus sounds better at the same size. Convert for compatibility, not for quality.
