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 to skip

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.
