Best practices for FLAC
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.
- FLAC is lossless — ideal for editing or archiving. Expect files several times larger than an MP3 or AAC equivalent.
- Check that title, artist, album and cover art survived the conversion; some players cache old tags.
When NOT to convert to FLAC
Cases where a different format serves you better.
When the file must play on older devices
FLAC is not supported everywhere (Wide). For old phones, car stereos, or legacy software, MP3 or AAC is a safer choice than FLAC.
