Converting WAV to FLAC changes the container or codec while preserving full audio quality. This is useful when your target device or application requires a specific audio format.
WAV (Waveform Audio File Format, introduced in 1991) uses None (raw PCM) or optional IEEE float compression. FLAC (Free Lossless Audio Codec, introduced in 2001) uses Lossless (linear prediction + Rice coding) compression. WAV browser support: Universal. FLAC browser support: All modern browsers (Chrome, Firefox, Edge; Safari 11+).
Both WAV and FLAC use lossless compression. The conversion preserves 100% of the original data — the output file is pixel-for-pixel (or sample-for-sample) identical to the input. No quality is lost during this conversion.
Typical WAV file size: A 4-minute song at 44.1 kHz/16-bit stereo: ~40 MB. Typical FLAC file size: A 4-minute song at 44.1 kHz/16-bit: ~20-30 MB. Expect a dramatic file size reduction — often 5-20x smaller — when converting from uncompressed WAV to FLAC.
FLAC compression level (0-8) only affects encoding speed and file size, not audio quality — all levels produce bit-identical audio. Level 5 is a good default balance. Levels 6-8 save marginal space at significantly slower encoding speeds.
