Why convert WMA to WAV?
Editors and CD-burning tools often need WAV.
What happens when you convert WMA to WAV?
The WMA is decoded to 16-bit PCM WAV.
How does Fylo convert WMA to WAV?
Fylo decodes the WMA audio in the WMA with ffmpeg compiled to WebAssembly and encodes it with 16-bit little-endian PCM with no compression. Nothing is added back: the WAV is an exact but larger copy of the decoded WMA (≈ 32 MB for a 3-minute song versus ≈ 3.6 MB at 160 kbps). The original sample rate and channel layout are kept unless you change them under Advanced.
What's the difference between WMA and WAV?
WMA (Windows Media Audio) was released by Microsoft in 1999 to compete with MP3 and is stored in the ASF container. Windows Media Player ripped CDs to WMA by default for years, so many older music collections are WMA.
WAV was introduced by Microsoft and IBM in 1991 and, like AVI, uses the RIFF container. Most WAVs hold uncompressed PCM audio: CD quality (44.1 kHz, 16-bit, stereo) runs at 1,411 kbps, or about 10.6 MB per minute.

Frequently asked questions
Does converting WMA to WAV improve quality?
No. WMA is lossy, so detail removed during its compression can't be restored. The WAV is a lossless copy of what the WMA sounds like — bigger, but not better.
Can I burn the WAV to CD?
Yes, 44.1 kHz 16-bit stereo WAV is CD-ready.
Is my WMA file uploaded to a server?
No. Fylo runs ffmpeg, the same engine used by professional video tools, compiled to WebAssembly inside your browser. Your WMA file is read directly from your device and never sent anywhere.
