CAF to AIF Converter
Processing entirely on your device — large files may take a moment.
Core Audio Format and Audio Interchange File (AIF) exist for different jobs: CAF is Apple's Core Audio container — Logic Pro projects and macOS system sounds live in it, with support for huge files and any codec. Convert AIF exactly as you would AIFF: to WAV for Windows tools, or to MP3/FLAC for sharing.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the CAF format
CAF (Core Audio Format) is Apple's container for pro audio: 64-bit file offsets for recordings of any length, any codec as payload (PCM, ALAC, AAC), and time-stamped MIDI-style event chunks. Logic Pro exports it and macOS system sounds ship in it.
ffmpeg decodes the common PCM/ALAC payload variants, converting CAF to WAV or MP3 for use in any non-Apple DAW, player or web player.
+ Strengths
- ✓64-bit offsets — no size ceilings
- ✓Native to Logic Pro pipelines
- ✓Flexible codec payload
! Limitations
- −Apple-centric — rare outside macOS
- −Some CAF variants (UUID chunks) unsupported
- −Tag metadata Apple-specific
About the AIF format
AIFF is Apple's counterpart to WAV: uncompressed PCM in an IFF container, born with the classic Mac in 1988. It stores the same bit-perfect audio as WAV but carries metadata far better — iTunes-era tags, cover art and loop points all fit natively, which made it the default of Logic Pro and Mac-based audio production.
Functionally the WAV-versus-AIFF choice is platform history: same quality, same sizes, AIFF friendlier on Mac, WAV friendlier everywhere else. Converting between them is a lossless retagging exercise, nothing more.
+ Strengths
- ✓Bit-perfect uncompressed audio
- ✓Better metadata support than WAV
- ✓Native to macOS and Logic Pro
! Limitations
- −Same bulk as WAV (~10 MB/minute)
- −Windows tooling historically prefers WAV
Why convert CAF to AIF?
There is a concrete reason this conversion exists: Apple-centric — rare outside macOS AIF sidesteps that — Bit-perfect uncompressed audio If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this CAF to AIF converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for CAF to AIF?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
Will converting CAF to AIF reduce audio quality?
If AIF is lossless, the output contains everything the CAF file contains — no further loss is added. If AIF is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
