Frequently asked questions
Will the FLAC lose quality?
No. Both formats are lossless, so every pixel or sample in your AIFF is kept exactly.
Will the FLAC be smaller than the AIFF?
Usually yes: a minute of audio takes about 10.6 MB as AIFF and about 6.4 MB as FLAC. FLAC is lossless, so its size depends on the audio rather than a bitrate setting.
