Why convert M4A to FLAC?
M4A is the audio-only counterpart of MP4, typically containing AAC-encoded audio. It's the default audio format for Apple's ecosystem — iTunes, Apple Music, and iPhones all use M4A by default. FLAC is an open-source lossless audio format that compresses files by 30–60% with zero quality loss. It's the favorite of audiophiles and music archivists who want CD-quality sound without the bulk of WAV. Converting from M4A to FLAC is useful when you need high-resolution music libraries or want to take advantage of truly lossless compression.
