FLAC provides a lossless container for archival. Convert AAC to FLAC if you need a lossless format for your workflow.
AAC is the successor to MP3, offering better sound quality at similar or lower bitrates. It's the default audio codec for YouTube, Apple Music, and most streaming platforms.
FLAC is an open-source lossless audio codec that compresses audio without any quality loss. Files are typically 50-60% of the original WAV size while maintaining bit-perfect reproduction.
AAC is lossy. FLAC is lossless. Converting won't improve quality but changes the container format.
