Frequently asked questions

Why convert MP3 to OGG?

Opus compresses more efficiently than MP3 at equal quality, so files are smaller — useful for web apps and open-source workflows.

Will I notice a quality drop?

Re-encoding lossy to lossy always costs a little. Keep the original MP3 if you need maximum fidelity.

Is OGG compatible with my music player?

Modern browsers, VLC and most Linux/open-source players handle OGG natively; Apple Music and some car systems do not.
