How do I convert WMA to WAV?

Add your WMA file to the upload area above, then press Convert. The WAV file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to WAV reduce quality?

No. WAV is a lossless format, so the conversion preserves exactly what is in your WMA file. Note that it cannot recover detail that was already discarded when the WMA was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 300 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

WMA and WAV explained

WMA is Microsoft's audio format from the Windows Media era. It is functionally obsolete and some older files carry DRM that prevents conversion.

WAV stores uncompressed PCM audio — the raw samples, exactly as captured. A stereo CD-quality minute is roughly 10 MB, which is the price of having no compression whatsoever.

Where WMA files come from: Music ripped on Windows in the 2000s.
Where WAV is used: Recording sessions, sample libraries and audio editing.

WMA vs WAV

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

WMA compared with WAV
Property	Source	Target
Compression	Lossy	Uncompressed
Introduced	1999	1991
Browser support	Windows only. Convert for anything else.	Universal.

WMA is stronger at: Reasonable quality for its time.
WAV is stronger at: Perfect fidelity with zero compression artefacts. No decoding overhead, so editors scrub instantly. Universally supported.

Why convert WMA to WAV?

People make this switch when they run into the limits of WMA: always — convert to MP3 to keep the audio usable. WAV is the better fit when recording, editing, mastering, or handing audio to another tool.

Be aware of the size trade-off: WAV is uncompressed, so expect the converted file to be considerably larger than the WMA you started with.

WMA limitations that prompt the switch: Windows-only in practice. No browser or mobile support worth relying on. DRM-protected files cannot be converted at all.
What you give up: Very large files. No standard metadata support worth relying on.

Does converting WMA to WAV reduce quality?

Going from WMA to WAV moves already-compressed data into a format that stores it exactly. Nothing is lost from this point on, but nothing is recovered either — the detail WMA discarded when the file was first created is gone permanently. Expect a noticeably larger file for identical visual quality.
