Why convert FLAC to AAC?

  • Get FLAC-sourced music into the Apple Music app and iTunes, which have never supported FLAC playback.
  • Carry four to five times more music on a phone — 256 kbps AAC runs about a quarter the size of typical FLAC.
  • Produce the cleanest possible AAC, with no stacked compression from earlier lossy steps.

Tip: 256 kbps AAC is effectively transparent for most listeners and gear; keep the FLAC files as masters so you can re-encode to any future format without loss.
