Should you convert WMA to WAV?
An editor needs old Windows Media Audio as plain WAV.
Only when software insists on WAV. It stores the decoded WMA perfectly, but the detail the WMA discarded is already gone, so the WAV is bigger without sounding better.
WAV also plays in more places: every computer, audio editor and DAW, and most phones.
WMA is the Windows Media audio format from the Windows XP era; WAV is uncompressed, studio-quality audio. Use WAV while editing and for systems that demand it, such as phone systems, samplers and some broadcast tools.

What changes when WMA becomes WAV
Bigger, not better
WAV can’t restore what WMA compression removed. It does make editing easier and stops further loss, which is why editors and some broadcast systems ask for it.
A one-time engine download
WMA is decoded by FFmpeg compiled to WebAssembly, a 31 MB download the first time. After that it is cached, and the conversion never leaves your device.
Expect a much larger file
WAV is far bigger for the same content. Choose it because something needs WAV, not to send or store the file. WMA: Similar to MP3. WAV: About 10 MB a minute at CD quality.
This page is put together from our notes on each format, choosing only what is true of WMA and WAV, so every pairing states the same facts the same way. How these pages are made.
Why it doesn’t upload
Recordings are often private: interviews, voice notes, unreleased music. Your browser can decode and encode audio itself, so there is no reason to send it anywhere.
How to check for yourselfWorth knowing
- About the WMA. WMA files bought from old online stores are often DRM-protected; no converter can open those.
- About the WAV. A WAV made from an MP3 is ten times bigger but sounds exactly like the MP3; the lost detail doesn’t come back.
- MP3, WAV, M4A, OGG, Opus and FLAC are converted by your browser directly. WMA, AMR, APE, AC3 and the other specialist formats use the FFmpeg engine, a one-time 31 MB download.
