How to convert WAV to WMA
Add your WAV files
Drag and drop WAV files into the box or tap to choose them. The converter engine (about 31 MB) downloads once, the first time you convert.
Pick a bitrate
192 kbps suits music and 128 kbps or less suits speech. Sample rate and mono/stereo are under Advanced.
Convert and download
Click Convert, then download each WMA file or all of them as one ZIP.
Why convert WAV to WMA?
Some older Windows tools and phone systems expect WMA.
What happens when you convert WAV to WMA?
The WAV is encoded to WMA2 at 192 kbps, about 85% smaller.
How does Fylo convert WAV to WMA?
Fylo decodes the PCM audio in the WAV with ffmpeg compiled to WebAssembly and encodes it with Windows Media Audio 2 (wmav2) at 192 kbps in an ASF container. Going from lossless to lossy is where the big saving happens: a 3-minute song is ≈ 32 MB as WAV but ≈ 3.6 MB at 160 kbps as WMA. The original sample rate and channel layout are kept unless you change them under Advanced.
What's the difference between WAV and 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.
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.

Frequently asked questions
Is WMA widely supported?
Mostly on Windows. MP3 is more universal.
Does it keep stereo?
Yes, unless you choose mono under Advanced.
Is my WAV file uploaded to a server?
No. Fylo runs ffmpeg, the same engine used by professional video tools, compiled to WebAssembly inside your browser. Your WAV file is read directly from your device and never sent anywhere.
