M2V to CAF Converter
Processing entirely on your device — large files may take a moment.
M2V is a raw MPEG-2 video elementary stream — DVD and broadcast video stripped of its container, the export format of choice of many editors. Convert CAF files to WAV or MP3 for use outside the Apple ecosystem.
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 M2V format
M2V is the MPEG-2 video elementary stream — the video layer of DVDs and digital broadcast, exported bare by editors who want to mux it with audio separately. It is the professional half of a DVD's guts.
Muxing M2V with its audio into MP4 or MKV restores a playable file; the video often stream-copies without re-encoding since MPEG-2 data is already valid in modern containers.
+ Strengths
- ✓Broadcast/DVD grade MPEG-2 quality
- ✓Often stream-copyable without re-encode
- ✓Standard editor export format
! Limitations
- −No audio inside — pair it before muxing
- −Large for HD (MPEG-2 efficiency)
- −Interlaced flags need care
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 M2V to CAF?
Think of it as moving your file to the container that fits the job. No audio inside — pair it before muxing CAF works differently: 64-bit offsets — no size ceilings If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this M2V 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 M2V 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 M2V 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.
