Quick answer: To convert WMA to WAV, add the WMA file to the iHateFiles WMA to WAV converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. A lossless target, so nothing is thrown away in this step.
Should you convert WMA to WAV?
Do this when an editor, DAW or device needs WAV. It will not make the WMA sound any better, and the file grows several times over.
WAV will not restore what WMA removed
WAV stores every sample exactly, including the damage WMA compression already did. Expect about 10 MB per minute instead of 1 MB or so, for audio that sounds identical. Do it because an editor or device needs WAV, not to improve the sound.
Track details may not follow
WMA carries artist, album and cover art tags well. WAV has little or no room for them, so a music library that relies on tags may show the WAV as an untitled file.
Where the WAV will play
WAV plays on every editor, DAW and operating system.

What usually goes wrong
About the WMA. A WMA bought from an early music store may be DRM-locked, and no conversion can lawfully unlock it. A WMA you ripped yourself converts without any trouble.
About the WAV. Converting an MP3 to WAV makes the file ten times larger without recovering anything. The detail the MP3 discarded is gone.
How to convert WMA to WAV

Questions
How do I convert WMA to WAV?
Open this page, add your WMA file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this WMA to WAV converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to WAV lose quality?
WAV is lossless, so this step throws nothing away. If the original was already a lossy format, the damage it did cannot be undone, but nothing further is lost.
Can I convert several WMA files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
