Why convert FLAC to AAC?
FLAC is lossless and large; AAC is lossy and small. Converting from FLAC gives AAC the best possible source, so at a high bitrate the result is transparent while taking a fraction of the space — perfect for phones and streaming. Many people keep a FLAC archive and sync AAC to their devices.
Does converting lose quality?
AAC is lossy, so it isn't a bit-perfect copy of the FLAC. But because you start from a lossless source, a 256–320 kbps AAC is transparent for almost all listeners. Keep the FLAC as your master. See AAC vs FLAC.
