Why convert FLAC to AAC?
AAC uses lossy compression, so expect a noticeably smaller file than the lossless FLAC original, at some cost to quality. The main reason to convert FLAC to AAC is compatibility: AAC plays on virtually any device or app without an extra codec, while FLAC doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, AAC is usually the safer target.
