What is an FLAC file?

FLAC files mostly belong to ffmpeg. FLAC files store audio in a lossless compression format. This means the sound data is preserved exactly as it was recorded, without any quality loss.
  • Function: They compress large audio files without discarding any details.
  • Playback: Use a FLAC-compatible media player, such as VLC, or a codec suite like ffmpeg.
  • Applications: Ideal for music collections and professional audio archiving.
  • FilExt.com tip: For more information, see the details available at ffmpeg.org.

If you cannot open your FLAC file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FLAC file directly in the browser:.
