Frequently asked questions
Will the MP3 lose quality?
Both formats are lossy, so converting re-encodes the data once more. Using a high quality setting keeps the generational loss very small. Avoid converting the same file back and forth repeatedly.
Will the MP3 be smaller than the Opus?
No, usually larger: a minute of audio takes about 1.0 MB as Opus and about 1.4 MB as MP3 at 192 kbps. Lower the bitrate to shrink it further; 128 kbps is plenty for speech.
