Why Convert M4V to MP4?

M4V is Apple's own spin on MP4, near-identical inside but wrapped so some players balk at the extension alone. Renaming the file is unreliable; a clean remux to standard MP4 fixes the compatibility, keeping the H.264 video where it can.

One caveat worth stating plainly: M4V bought from the iTunes Store carries FairPlay DRM and cannot be converted.

Frequently Asked Questions

Can I convert DRM-protected iTunes movies?
No. Films and shows purchased or rented from the iTunes Store are protected with Apple's FairPlay DRM, which cannot be removed by any converter. Only your own DRM-free M4V files go through.
Can I convert M4V to MP4 in the browser?
No. This pair runs in the desktop app through FFmpeg, locally on your Mac. Nothing is uploaded.
Can't I just rename the file to .mp4?
Sometimes, but not reliably. Some players read the internal box structure, not the extension, so a proper remux is the safe way to get a file that opens everywhere.
Will the quality change?
M4V already holds H.264 video, so a DRM-free file keeps its picture quality through the conversion. There is no upscaling; the output matches the source.
Is my file still private in the desktop app?
Yes. The desktop app converts with native engines on your Mac and works offline after a one-time activation check. Nothing is uploaded, in the browser or on desktop.
