MJPEG to CAF Converter
Processing entirely on your device — large files may take a moment.
Convert CAF files to WAV or MP3 for use outside the Apple ecosystem. If your files are still in MJPEG format, this page is the shortcut: MJPEG packs each video frame as its own JPEG — the format of IP cameras, capture cards and old edit decks. Huge files, zero inter-frame artifacts.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the MJPEG format
MJPEG records every video frame as its own complete JPEG — no inter-frame prediction at all. IP cameras, capture cards, older edit decks and even some aviation recorders output it. The result is huge files with legendary robustness: cut the file anywhere and every frame still decodes.
Converting MJPEG to H.264 MP4 typically shrinks files by 10-20x while keeping every frame's detail — the intra-only format wastes bits on static backgrounds that H.264 simply skips.
+ Strengths
- ✓Frame-accurate seeking and robustness
- ✓Every frame is a valid JPEG
- ✓No inter-frame corruption propagation
! Limitations
- −Enormous file sizes
- −No adaptive quality per scene
- −Baseline JPEG only in most hardware
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 MJPEG to CAF?
Converting makes sense where the strengths of CAF meet what MJPEG cannot give you. 64-bit offsets — no size ceilings Meanwhile Enormous file sizes One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MJPEG 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 MJPEG 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 MJPEG 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.
