WHY USE THIS TOOL

Store decoded audio losslessly without carrying video frames

FLAC is useful when you want lossless audio storage but prefer a more space-efficient format than uncompressed PCM WAV.

Lossless encoding

FLAC preserves the decoded audio information instead of applying lossy compression.

Audio-only result

Video frames are discarded to create a dedicated audio file.

Practical archive format

FLAC is widely used for lossless music libraries and archival workflows.

Good to know

FLAC cannot restore quality that was already lost in a compressed source track; it only avoids additional lossy encoding in the new file.
