Why convert WMA to FLAC?

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 vs FLAC: technical comparison

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+).

What happens to quality?

The quality impact depends on the specific settings used during conversion. FLAC preserves full quality with lossless compression.

File size impact

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.

Common use cases

  • Archiving audio in lossless FLAC format for long-term preservation
  • Converting WMA files to FLAC for compatibility with specific applications or workflows
  • Converting WMA files to FLAC for compatibility with specific applications or workflows
Pro tip

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.
