Frequently asked questions
Is FLAC completely lossless?+
Yes — FLAC is a lossless codec. The compression algorithm is reversible, meaning decompression produces the exact original PCM samples with no modification. This is mathematically verifiable with MD5 checksums, which FLAC stores internally for verification.
What FLAC compression level should I use?+
FLAC compression level (0–8) only affects encoding speed and file size, not audio quality. Level 5 is the default and provides a good balance. Level 8 produces the smallest file but takes longer to encode. Level 0 encodes fastest. All levels decode to identical audio.
Does FLAC work on iPhones and Android devices?+
Android supports FLAC natively since Android 3.1. iOS supports FLAC natively since iOS 11. Most modern music apps (VLC, Plex, foobar2000, Poweramp) play FLAC on both platforms. Apple Music and Spotify do not serve FLAC, but local FLAC files play in the native Music app on iOS.
