What is CAF?
Core Audio Format — Apple's audio container, used by GarageBand, Logic Pro, macOS/iOS voice recordings, and system sounds. It can hold PCM, ALAC, or AAC audio and supports very large files, but it's poorly supported outside the Apple ecosystem.
What is MP3?
The most widely used audio format. Great compatibility, small file size. Ideal for music, podcasts, and general use.
Why Convert CAF to MP3?
CAF (Core Audio Format) is Apple's own audio container, used by GarageBand, Logic Pro, macOS and iOS voice recordings, and macOS system sounds. Inside the Apple ecosystem it's convenient — it can hold huge files and multiple codecs — but the moment you step outside macOS and iOS, CAF becomes a problem. Windows doesn't recognize it, most Android apps can't open it, Google Drive and web players often refuse to preview it, and sending a .caf file to someone on a PC usually leaves them stuck. Converting to MP3 removes every one of those barriers, because MP3 plays on literally everything: Windows, Android, browsers, car stereos, DAWs, and every messaging and email client. This is especially useful when you export or capture audio on a Mac and need to hand it to someone who isn't on Apple hardware, or when you want to upload a recording to a platform that only accepts common formats. The converter decodes whatever audio the CAF contains — PCM, ALAC, or AAC — using FFmpeg compiled to WebAssembly, then re-encodes it to a standard MP3, all inside your browser. Nothing is uploaded, which matters when the recording is a private voice memo, an unreleased music idea, or client work. If your CAF holds lossless PCM or ALAC, you're moving to a smaller lossy MP3, which is the right trade for sharing and playback; keep the original CAF if you need the lossless master for editing.

Open Mac voice recordings anywhere
macOS and iOS recordings saved as CAF play instantly on Apple devices but not elsewhere. MP3 makes them universal.

Drop your .caf file into the converter above and download the MP3 it produces. The whole process runs in your browser — no upload, no signup, nothing sent to a server.
What is a CAF file?
CAF (Core Audio Format) is Apple's audio container, used by GarageBand, Logic Pro, and macOS/iOS recordings and system sounds. It can hold PCM, ALAC, or AAC audio, but it's poorly supported outside Apple devices — which is why converting to MP3 is so useful.
Why won't my CAF file play on Windows or Android?
CAF is an Apple format, and Windows Media Player, most Android apps, and many web players don't include support for it. MP3 is supported virtually everywhere, so converting removes the compatibility problem entirely.
Will I lose quality converting CAF to MP3?
If your CAF contains lossless PCM or ALAC audio, converting to MP3 is a lossy step, though at a good bitrate the difference is inaudible for most listening. If the CAF already holds AAC, you're moving between two lossy formats. Keep the original CAF if you need a lossless master for editing.
Is my audio uploaded when I convert?
No. Conversion runs entirely in your browser with FFmpeg WebAssembly, so your CAF file never leaves your device. That makes it safe for private recordings and unreleased music.
Is this CAF to MP3 converter free?
Yes. Free users get 5 conversions per month. The output is limited to the first 10 seconds as a preview, with a 20MB input file size limit. Upgrade to Pro for unlimited, full-length conversions.
