Heads up before converting to MP3
What this specific conversion changes about your audio.
Re-encoding Opus to MP3 stacks compression
Both Opus and MP3 are lossy, so converting between them compresses already-compressed audio and can add artifacts. When possible, convert from the original lossless master instead of from another lossy file.
Best practices for MP3
Small choices that keep your output sounding right.
- Play the first converted file before batch-converting the rest, so you catch a wrong setting early.
- For MP3, choose a bitrate that fits the use: 192–256 kbps keeps most music transparent, 320 kbps for archival-grade lossy.
- Check that title, artist, album and cover art survived the conversion; some players cache old tags.
