What changes in this conversion
- Converting to WAV stops any further quality loss, but it cannot restore audio detail already discarded by WMA. The file will usually get larger.
- WAV opens almost everywhere, so the converted file will work on devices and programs that refused the original WMA.
How to use
-
Add your WMA file
Drag the WMA file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
-
Confirm WAV as the output
WAV is already selected as the output format on this page. You can pick the bitrate — higher keeps more of the sound, lower makes a smaller file.
-
Run the conversion
Press the convert button. Audio decodes and re-encodes in your browser — a normal song finishes in a few seconds.
-
Download the WAV file
When it finishes, download the WAV file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions
Is converting WMA to WAV really free?
Yes. WMA to WAV conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
Are my WMA files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so the WMA file never leaves your device. That is also why it works without an internet connection once the page has loaded.
Is there a file size limit for WMA to WAV conversion?
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
