WMA to WAV on iPhone

Safari on iOS 15.4 and newer runs the converter completely, on the phone itself. There is no App Store download — and no converter app quietly uploading your recordings to its own servers. WMA files convert to WAV here the same way — nothing to install.

If the file is in Voice Memos or Photos, tap the share icon and choose 'Save to Files' first — that makes it visible to Safari's file picker. The converted file lands in Files (Downloads by default), from where you can share it into Messages, Mail, or any app. Your WMA comes out as WAV, ready to use straight away.

The WMA files people convert on an iPhone almost always originate from CDs ripped in Windows Media Player during the 2000s, when it was the Windows default, and WMA has been abandoned — macOS, iPhones, most Android apps, car stereos and smart speakers all skip it — which is precisely why they're stuck on the phone until you convert them to WAV.

WAV runs about 10 MB per minute against WMA's 1.2, so the file grows roughly 8×. Irrelevant for a session file; keep the original for archiving. No "HD upscaling" is possible from a lossy source. The audio is identical — WAV just stops it degrading further.

WMA to WAV is a common iPhone snag specifically because WMA has been abandoned — macOS, iPhones, most Android apps, car stereos and smart speakers all skip it, and WAV is what your other apps and devices expect. Apple gives you no built-in way to convert audio at all, so the App Store is full of converter apps — many upload your recording to their own servers, show ads against it, and want a subscription. Doing it in Safari means the WMA file is processed on the phone itself and stays there, which matters when it is a voice memo, an interview, or a recording of your own family.

Your WMA file never leaves the handset. For iPhone that is the whole argument: CDs ripped in Windows Media Player during the 2000s are usually personal, and the App Store alternative frequently ships them to a company's servers as the price of a free conversion. Processing the WMA-to-WAV conversion on-device means there is no server to trust in the first place.

Where does a WMA file even come from? Usually CDs ripped in Windows Media Player during the 2000s, when it was the Windows default. The catch is that WMA has been abandoned — macOS, iPhones, most Android apps, car stereos and smart speakers all skip it. WAV is the destination when you need uncompressed, edit-ready audio that every DAW and editor accepts. Expect growth, not shrinkage: about 10 MB per minute versus 1.2. That's the price of an uncompressed or lossless container, and it buys you an editing chain that costs nothing further. One honest note on this exact pair: WMA is already lossy, so moving to WAV cannot restore detail the WMA encoder discarded — it hands you an uncompressed container, not better audio, and the value is a loss-free chain from here on.
