What changes
- FLAC is lossless, but it can only preserve what is already in the OPUS file. Detail removed when the OPUS was first encoded does not come back — you get a bigger file of the same audio, not a better one.
- Cover art, lyrics, and most tags are not carried across — the output keeps the audio, not the metadata around it.
