Convert ALAC to FLAC — Free Online Converter

ALAC (Apple Lossless Audio Codec) and FLAC (Free Lossless Audio Codec) are both lossless audio codecs with similar compression ratios (40-60% vs raw PCM). ALAC is Apple's format, native to iOS, macOS, and Apple Music. FLAC is the open-source universal standard, native to Android, Linux, Windows 10+, and every major music platform (Bandcamp, Tidal, Qobuz, Amazon Music HD).

Converting ALAC to FLAC is a lossless-to-lossless transfer — the output is bit-for-bit identical to the original pre-compression audio. This is the standard migration path when moving from an Apple-centric music library to a cross-platform or open-source ecosystem.

FLAC has vastly broader device and platform support than ALAC. Android plays FLAC natively; it requires third-party apps for ALAC. Linux, Windows 10+, Bandcamp, Tidal, Qobuz, and virtually every music server (Plex, Roon, Jellyfin) support FLAC natively. ALAC is limited to Apple devices and software.

FLAC's metadata system (Vorbis comments) supports unlimited custom fields, embedded album art, ReplayGain values, and cue sheets. For organized music libraries on non-Apple platforms, FLAC is the superior format. The conversion preserves every audio sample perfectly — only the container and compression algorithm change.
