What is a FLAC file?

Free Lossless Audio Codec (.flac)

FLAC (Free Lossless Audio Codec) is an open-source audio format that provides lossless compression — reducing file sizes by 50-70% compared to WAV while preserving 100% of the original audio data. FLAC was created by Josh Coalson in 2001 and has become the gold standard for lossless music archiving. It supports sample rates up to 655,350 Hz, bit depths up to 32-bit, and up to 8 channels. FLAC includes extensive metadata support (Vorbis comments), embedded album art, and CUE sheet integration. The format is supported by most music players, streaming services (Tidal, Qobuz, Amazon Music HD), and audiophile hardware. FLAC decoding is computationally lightweight, making it suitable for portable devices. For audiophiles, FLAC represents the optimal balance between file size and perfect audio quality — significantly smaller than WAV but with zero compromise in sound reproduction.
