While converting WMA to FLAC will not recover audio data lost during the original compression, it creates a lossless container that prevents further degradation. This can be useful for archival or when your workflow requires lossless input files.
WMA (Windows Media Audio, introduced in 1999) uses Lossy (modified DCT) or Lossless compression. FLAC (Free Lossless Audio Codec, introduced in 2001) uses Lossless (linear prediction + Rice coding) compression. WMA browser support: Limited (Edge on Windows only). FLAC browser support: All modern browsers (Chrome, Firefox, Edge; Safari 11+).
The quality impact depends on the specific settings used during conversion. FLAC preserves full quality with lossless compression.
Typical WMA file size: A 4-minute song at 192 kbps: ~5.5 MB. Typical FLAC file size: A 4-minute song at 44.1 kHz/16-bit: ~20-30 MB. The FLAC output will be larger than the WMA input because lossless compression cannot match the compression ratios of lossy formats.
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.
