Convert CAF to FLAC — Free Online Converter

CAF (Core Audio Format) is Apple's professional container with unlimited codec support, no file size cap, and rich production metadata. FLAC (Free Lossless Audio Codec) is the universal open-source lossless standard, supported on Android, Linux, Windows 10+, and every major music platform.

Converting CAF to FLAC extracts the audio, decodes to PCM, and encodes losslessly. From PCM or ALAC in CAF, this is a perfectly lossless operation. FLAC provides cross-platform lossless compatibility that CAF lacks.

CAF is macOS-specific with virtually no support outside Apple's Core Audio framework. FLAC is supported everywhere — Android, Linux, Windows, Plex, Roon, Jellyfin, Bandcamp, Tidal, and Qobuz. Converting CAF to FLAC makes professional macOS recordings accessible on all platforms.

FLAC's Vorbis comment metadata system supports unlimited tagging, ReplayGain, embedded album art, and cue sheets. For distributing professional recordings outside the Apple ecosystem, FLAC is the universal lossless choice.
