Convert CAF to MP3.
CAF is Apple's Core Audio container, common in iOS apps and GarageBand, and unfamiliar to almost everything else. Convert it to MP3 that plays on any device and app.

Apple's audio container
CAF was built by Apple to get around the size limits of older formats. It can hold enormous recordings and a wide range of codecs, which makes it handy inside apps and recording tools on iOS and macOS. The trade-off is reach: hand a .caf to a Windows PC, an Android phone or most web players and it simply won't open. MP3 is the universal fallback.
Out of the app, onto your devices
Convert when you want a recording out of an app's CAF export and into something you can play, share or send anywhere, and transcribe with TranscriptAI if it's speech.

CAF to MP3: re-encoded
MP3 is a compressed, lossy audio format, so this re-encodes the sound and the file gets smaller. Every lossy re-encode sheds a little quality, so convert from the best source you have rather than chaining conversions.

Common questions
What is a CAF file?+
CAF (Core Audio Format) is Apple's flexible audio container, used by iOS apps, GarageBand and macOS audio tools. It can hold very long or high-quality recordings, but outside Apple's ecosystem most players don't recognise it: MP3 does.
Is it free?+
Yes. Convert CAF to MP3 free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
What about quality?+
We re-encode at a high MP3 bitrate, so for music and speech the result stays faithful to the source.
