What is a FLAC File?

A FLAC file is a digital audio file format that uses lossless compression to reduce file size while preserving the original audio quality. FLAC stands for Free Lossless Audio Codec, meaning the audio can be compressed and later restored to exactly the same quality as the original recording.

Unlike lossy formats such as MP3, which remove some audio data to reduce file size, FLAC compresses audio without permanently discarding information. When a FLAC file is decoded, the audio is identical to the original source.

FLAC files typically take up less storage space than uncompressed formats such as WAV, while still maintaining full sound quality. Because of this, FLAC is commonly used for high-quality music archives, audiophile playback, and digital music libraries.

FLAC is an open-source format and is widely supported across many audio players and production tools. Audio engineers and producers can work with FLAC files in digital audio workstations such as Ableton Live, FL Studio, and Logic Pro when storing or distributing high-quality audio recordings.
