Why won't my OPUS file play on my device?

OPUS support is built into web browsers and some apps, but many media players, car stereos, and older devices don't include an OPUS decoder. Converting to MP3 solves the compatibility problem.

Does converting OPUS to MP3 reduce quality?

MP3 is a lossy format, so some audio information is discarded. At 192 kbps or higher, most people can't hear the difference compared to the OPUS original on typical listening setups.

Are my files uploaded to a server?

No. All conversion runs in your browser using WebAssembly. Your files never leave your device.

Yes, completely free with no account or software download required.
