M2V to M4B 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. Converting M4B to MP3 frees audiobooks to play on car stereos, dumb players and anything without chapter support.
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 M4B format
M4B is M4A wearing an audiobook badge: the same AAC audio in an MP4 container, plus chapter markers that Apple Books and Audible apps render as a scrubbing timeline. Buy an audiobook outside Audible and it likely arrives as M4B.
The format is deliberately chained to Apple's book ecosystem. Converting M4B to MP3 sets the book free: car stereos, gym players, old iPods and every app without chapter support will play it — though the chapter marks themselves are flattened away.
+ Strengths
- ✓Chapter markers survive on Apple platforms
- ✓Efficient AAC audio
! Limitations
- −Chapters vanish in MP3 conversion
- −Non-Apple support is patchy
Why convert M2V to M4B?
Think of it as moving your file to the container that fits the job. No audio inside — pair it before muxing M4B works differently: Chapter markers survive on Apple platforms 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 M4B 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 M4B?
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.
Does converting M2V to M4B 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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of M4B, staying in sync with the video. If your M2V file has multiple audio tracks, the first one is used.
