Why FLAC files are used
Free Lossless Audio Codec files store digital audio using the .flac extension.
Audio formats differ in compression, quality, metadata, channel support and compatibility with players and editing software.
What to know about FLAC
Audio encoding
FLAC uses format-specific rules to store or compress sound.
Quality and size
Bit rate, sample rate, bit depth and compression influence both fidelity and file size.
Metadata
Track titles, artists, artwork and other tags may be supported depending on the format.
Compatibility
Support for FLAC varies across browsers, devices, editors and media players.
How FLAC conversion works
Converting FLAC decodes the source audio and encodes it with the destination format's codec and selected quality settings.
Lossy conversion cannot restore detail already removed from the source, so keep the original when quality matters.
mp3.now accepts FLAC as input and can also create FLAC output.
FLAC compatibility and software support
Check that the target player or editing application supports FLAC before choosing it for delivery.
MP3 remains a practical fallback when broad playback compatibility is the priority.
