FLAC 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. FLAC 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 FLAC comes out as WAV, ready to use straight away.

The FLAC files people convert on an iPhone almost always originate from CD rips, hi-res download stores, and archival libraries, and FLAC is lossless but poorly supported outside audiophile software — Apple's Music app won't touch it — which is precisely why they're stuck on the phone until you convert them to WAV.

Expect a similar file size; the reason to convert is playback and workflow, not disk. This conversion costs you nothing in quality — it's compression in the ZIP sense, not the MP3 sense.

FLAC to WAV is a common iPhone snag specifically because FLAC is lossless but poorly supported outside audiophile software — Apple's Music app won't touch 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 FLAC 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 FLAC file never leaves the handset. For iPhone that is the whole argument: CD rips 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 FLAC-to-WAV conversion on-device means there is no server to trust in the first place.

Where does a FLAC file even come from? Usually CD rips, hi-res download stores, and archival libraries. The catch is that FLAC is lossless but poorly supported outside audiophile software — Apple's Music app won't touch it. WAV is the destination when you need uncompressed, edit-ready audio that every DAW and editor accepts. Sizes are comparable: FLAC and WAV both sit near 5–10 MB per stereo minute, so this conversion is about compatibility, not storage. Both FLAC and WAV are lossless, so this specific conversion is bit-perfect: every sample survives and you can go back to FLAC later without any loss.
