What is the difference between M4V and MP4?

The containers are closely related, but M4V is commonly associated with Apple workflows and may contain copy protection. MP4 is recognized more broadly.

Can protected iTunes M4V files be converted?

No. The converter cannot decrypt DRM-protected purchases or rentals.

Will an unprotected M4V play after conversion?

Supported M4V video is encoded as H.264/AAC MP4 for broad playback compatibility.

No. The file is processed locally in your browser.

M4V is an Apple-associated container closely related to MP4. Unprotected M4V files can be converted to standard H.264/AAC MP4 for easier use outside Apple software. This preset re-encodes the primary streams for predictable playback. DRM-protected purchases cannot be opened or converted. Personal and unencrypted M4V files remain on your device because the conversion pipeline runs entirely inside the browser.
