AIF to CAF Converter
Convert AIF files to CAF format online for free. No installation or registration required.
Quick Answer: How to Convert AIF to CAF
AIF is the common extension for AIFF audio on systems limited to three-letter extensions. CAF is Apple's Core Audio Format, a modern container without the 4 GB ceiling of older formats. Converting between them re-encodes the media with CAF's compression model, so output quality depends on the settings you pick in the converter. Run it free at practicalwebtools.com/convert/audio/aif-to-caf: drop in your AIF, adjust settings if you like, and download the CAF — no signup, no upload, everything stays on your device.
AIF vs CAF: Which One and Why
AIF is the common extension for AIFF audio on systems limited to three-letter extensions, same format as AIFF (Apple, 1988). CAF is Apple's Core Audio Format, a modern container without the 4 GB ceiling of older formats, introduced by Apple in 2005 with Core Audio. People reach for AIF mainly for interchange with older pro-audio tools, legacy sample libraries, while CAF is the usual choice for iOS/macOS system sounds, Logic Pro and Final Cut intermediates. AIF's headline strength: identical audio fidelity to .aiff files. CAF's: no practical file-size limit. On the other side of the ledger, AIF limitation: purely a naming convention — some software treats .aif differently for import filters — and CAF limitation: little support outside the Apple ecosystem.
How to Convert AIF to CAF Online
- 1
Add your AIF file: Drag and drop it into the converter, or click to browse. AIF files up to the size limit are accepted, and nothing is uploaded — processing runs locally in your browser.
- 2
Set CAF options: Pick your quality: the converter exposes the settings that matter for CAF. Higher bitrates preserve more of the AIF's detail at larger file sizes.
- 3
Download the CAF: Conversion runs on your device. When it completes, download the CAF file — repeat for as many files as you need, free and unlimited.
Key Facts
- AIF: same format as AIFF (Apple, 1988), uncompressed PCM, like AIFF.
- CAF: introduced by Apple in 2005 with Core Audio, container — holds PCM, AAC, ALAC, MP3, or any Core Audio codec.
- AIF strength: identical audio fidelity to .aiff files.
- CAF strength: no practical file-size limit.
- AIF limitation to know: purely a naming convention — some software treats .aif differently for import filters.
- CAF limitation to know: little support outside the Apple ecosystem.
- Under the hood: CAF is one of the few formats that can store audio chunks out of order — useful for editing apps that append data while recording

AIF
AIF — same format as AIFF (Apple, 1988). .aif and .aiff are the same format; the shorter spelling survives from Windows and old Mac OS file-name limits
CAF
CAF — introduced by Apple in 2005 with Core Audio. CAF is one of the few formats that can store audio chunks out of order — useful for editing apps that append data while recording
Frequently Asked Questions
Will converting AIF to CAF lose quality?
It depends on the formats: AIF is uncompressed PCM, like AIFF and CAF is container — holds PCM, AAC, ALAC, MP3, or any Core Audio codec. Any step from a lossless source into CAF keeps everything; any lossy step re-encodes and discards some data.
Are my files uploaded anywhere during AIF → CAF conversion?
No. This converter runs on WebAssembly inside your browser — your AIF file is read from disk, processed by your device's CPU, and the CAF is written back locally. There is no server upload at any point, which also means no size-based throttling or waiting in queue.
What devices and apps play CAF files?
macOS and iOS system-level; Logic Pro, Final Cut. Little support outside the Apple ecosystem — worth knowing before you standardize on it.
Can I convert several AIF files at once?
Yes — the converter processes a queue of files in one session, each entirely on your device. Batch mode is handy when moving a library into CAF; just remember each file re-encodes independently, so set your quality once and it applies to all.
