Opus (.opus) · Max 20 MB
Re-encoding from one lossy format to another compounds compression artifacts. The second encoder discards data that the first encoder already altered.
To minimize damage, use the highest output bitrate AudioUtils offers. 320kbps is ideal. Avoid multiple round-trips between lossy formats.
If you have access to the original lossless source, convert from that instead. One lossy encode always beats two.
