info About this tool
Convert uncompressed WAV files to FLAC (Free Lossless Audio Codec) format. WAV is the gold standard for uncompressed audio: it contains every bit of audio information with zero quality loss, but files are enormous. FLAC applies lossless compression to the same audio, reducing file size by 40 to 60 percent while preserving every single audio sample. The resulting FLAC file sounds bit-for-bit identical to the original WAV. Audiophiles, archivists, and music producers use FLAC as their standard archive format.

File size: FLAC is typically 40 to 60 percent smaller than the equivalent WAV file.

Quality: Lossless compression. The FLAC output is bit-for-bit identical to the WAV source. Zero quality loss.

help FAQ

Is there any quality loss?

None. FLAC is a lossless format. Every single audio sample from the WAV is preserved exactly. The compression is mathematically reversible, like a ZIP file for audio.

How much smaller will the FLAC be?

Typically 40 to 60 percent smaller than the source WAV. A 30 MB WAV of a CD track usually becomes 12 to 18 MB as FLAC.

Which players support FLAC?

FLAC is supported by VLC, Foobar2000, most Android players, and all major music software. iPhone requires third-party apps.
