MOV to CAF Converter
Processing entirely on your device — large files may take a moment.
MOV is Apple QuickTime’s native video container. iPhones and DSLRs record to it, but Windows and Android apps often struggle with it. Convert CAF files to WAV or MP3 for use outside the Apple ecosystem.
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 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
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
Why convert MOV to CAF?
Converting makes sense where the strengths of CAF meet what MOV cannot give you. 64-bit offsets — no size ceilings Meanwhile Editing codecs produce enormous files One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MOV to CAF 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 MOV to CAF?
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.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
Does converting MOV to CAF re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
