AIFF 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. AIFF 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 AIFF comes out as OGG, ready to use straight away.

The AIFF files people convert on an iPhone almost always originate from Logic Pro and GarageBand bounces, old iTunes rips, and Mac sample libraries, and AIFF is uncompressed like WAV, so a four-minute song is 40 MB+ and won't attach to an email — which is precisely why they're stuck on the phone until you convert them to OGG.

AIFF costs you around 10 MB for every minute; OGG asks for about 1.2. Over a long recording that gap is the whole reason to convert. Starting from AIFF means the encoder isn't working around someone else's compression. That's why this produces a better OGG than converting from an already-lossy file would.

AIFF to OGG is a common iPhone snag specifically because AIFF is uncompressed like WAV, so a four-minute song is 40 MB+ and won't attach to an email, 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 AIFF 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 AIFF file never leaves the handset. For iPhone that is the whole argument: Logic Pro and GarageBand bounces 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 AIFF-to-OGG conversion on-device means there is no server to trust in the first place.

The AIFF on your drive almost certainly started life in Logic Pro and GarageBand bounces, and AIFF is uncompressed like WAV, so a four-minute song is 40 MB+ and won't attach to an email. OGG is the destination because it plays essentially everywhere — game assets and every ordinary phone, browser, and player. A minute of AIFF is about 10 MB; the same minute as OGG is roughly 1.2. Across an album or a long recording that difference decides whether it fits on a phone. Because AIFF is uncompressed, encoding to OGG here is the clean, single-generation case — the encoder sees the whole original signal, so this OGG is as good as the format gets.
