WMA to OGG 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 OGG 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 OGG, 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 OGG.

Sizes are comparable: WMA and OGG both sit near 1.2–1.2 MB per stereo minute, so this conversion is about compatibility, not storage. You're stacking a second lossy generation. At a generous bitrate that's inaudible, but if you still have a lossless original, encode from that instead: one generation always beats two.

WMA to OGG 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 OGG 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-OGG conversion on-device means there is no server to trust in the first place.

Most people meet WMA through CDs ripped in Windows Media Player during the 2000s. It is a fine format there; the trouble is that WMA has been abandoned — macOS, iPhones, most Android apps, car stereos and smart speakers all skip it. OGG is the destination because it plays essentially everywhere — game assets and every ordinary phone, browser, and player. Disk usage barely moves — this conversion buys compatibility rather than space. Both WMA and OGG are lossy, so this pair stacks a second encode — at a generous bitrate it stays inaudible, but if a lossless original of the WMA exists, encode the OGG from that instead.
