Quick Answer: How to Convert CAF to ALAC

CAF is Apple's Core Audio Format, a modern container without the 4 GB ceiling of older formats. ALAC is Apple Lossless — FLAC's counterpart inside the MP4/M4A container. Converting between them re-encodes the media with ALAC's compression model, so output quality depends on the settings you pick in the converter. Run it free at practicalwebtools.com/convert/audio/caf-to-alac: drop in your CAF, adjust settings if you like, and download the ALAC — no signup, no upload, everything stays on your device.

CAF vs ALAC: Which One and Why

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. ALAC is Apple Lossless — FLAC's counterpart inside the MP4/M4A container, released by Apple in 2004; open-sourced under Apache 2.0 in 2011. People reach for CAF mainly for iOS/macOS system sounds, Logic Pro and Final Cut intermediates, while ALAC is the usual choice for Apple Music lossless streaming, ripping CDs for the Apple ecosystem, iPhone/local-library audiophile setups. CAF's headline strength: no practical file-size limit. ALAC's: perfect fidelity inside the iTunes/Apple Music pipeline. On the other side of the ledger, CAF limitation: little support outside the Apple ecosystem — and ALAC limitation: no advantage over FLAC outside the Apple world.

Key Facts

  • CAF: introduced by Apple in 2005 with Core Audio, container — holds PCM, AAC, ALAC, MP3, or any Core Audio codec.
  • ALAC: released by Apple in 2004; open-sourced under Apache 2.0 in 2011, lossless — roughly 40–60% of original size, comparable to FLAC.
  • CAF strength: no practical file-size limit.
  • ALAC strength: perfect fidelity inside the iTunes/Apple Music pipeline.
  • CAF limitation to know: little support outside the Apple ecosystem.
  • ALAC limitation to know: no advantage over FLAC outside the Apple world.
  • Fun fact: Apple Music streams ALAC up to 24-bit/192 kHz — but AirPods re-compress it to AAC over Bluetooth, so lossless is only audible on wired or Wi-Fi playback

Format Background

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

ALAC

ALAC — released by Apple in 2004; open-sourced under Apache 2.0 in 2011. Apple Music streams ALAC up to 24-bit/192 kHz — but AirPods re-compress it to AAC over Bluetooth, so lossless is only audible on wired or Wi-Fi playback

Frequently Asked Questions

Will converting CAF to ALAC lose quality?

It depends on the formats: CAF is container — holds PCM, AAC, ALAC, MP3, or any Core Audio codec and ALAC is lossless — roughly 40–60% of original size, comparable to FLAC. Any step from a lossless source into ALAC keeps everything; any lossy step re-encodes and discards some data.

Are my files uploaded anywhere during CAF → ALAC conversion?

No. This converter runs on WebAssembly inside your browser — your CAF file is read from disk, processed by your device's CPU, and the ALAC is written back locally. There is no server upload at any point, which also means no size-based throttling or waiting in queue.

Does the converter keep metadata (title, artist, cover art)?

Where the ALAC container supports it, standard tags are carried across. Apple Music streams ALAC up to 24-bit/192 kHz — but AirPods re-compress it to AAC over Bluetooth, so lossless is only audible on wired or Wi-Fi playback

What ALAC settings should I choose?

For Apple Music lossless streaming, start with the converter's default preset — it's tuned for the common case. If you need smaller files, step quality down gradually and listen or look at the result before batch-converting everything.
