Your audio stays in your browser

OpusMP3 is a static browser-based converter. The selected audio file is processed locally by your browser and is not uploaded to a backend server by this site.

Files

Files you choose are used only for the current conversion session. Reloading or closing the page clears the selected file and generated download URL.

Analytics

This MVP does not include analytics scripts. If analytics are added later, keep them privacy-friendly and avoid collecting file names or audio contents.

Encoder script

The page includes a local copy of the lamejs MP3 encoder. The audio file itself remains in the browser during conversion.
