CAF to MOV Converter
Processing entirely on your device — large files may take a moment.
MOV keeps high production quality, which makes it a favourite intermediate format for video editing before final export. If your files are still in CAF format, this page is the shortcut: 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.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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 MOV format
MOV is Apple's QuickTime container, and technically the elder sibling of MP4 — same ISO base media format, same codec freedom. What sets it apart is professional video: ProRes intermediate codecs, timecode tracks and alpha channels live in MOV, which is why Final Cut, Premiere and every camera that shoots Apple ProRes hand you MOV files.
For everyday sharing it behaves exactly like MP4 (an H.264 MOV is interchangeable in practice). Where it hurts is size: ProRes and other editing codecs run hundreds of gigabytes per hour by design — they prioritize frame-accurate editing over compactness.
+ Strengths
- ✓Native to macOS, iOS and pro editing suites
- ✓Carries ProRes, alpha and timecode tracks
- ✓MP4-compatible for standard codecs
! Limitations
- −Editing codecs produce enormous files
- −ProRes playback needs capable hardware/players

Frequently asked questions
Is this CAF to MOV 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 MOV?
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.
Can I convert a whole folder of CAF files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
