CAF → MP3

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.

How it works

  1. 01

    Add your CAF

    Drop one or many .caf files, or click to browse. Private by default.

  2. 02

    Convert with a local engine

    CAF becomes MP3 with ffmpeg — no paid API in the loop.

  3. 03

    Download or transcribe

    Grab your MP3, or send it to TranscriptAI for a transcript.

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, with no signup. Paid plans add larger files and bigger batches.

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.
