How to convert MP4 to M4V
Add your MP4 videos
Drop MP4 files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
M4V is already chosen
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab and can take a while for large files.
Download
Save the M4V, or download everything as one ZIP if you converted several files.
Why ToAny
Private by construction
The MP4 to M4V converter is part of this page and runs inside your browser. Your videos are never sent to ToAny or to anyone else.
No upload, no queue
Nothing has to travel to a server and back, so work starts the moment you press Convert. How long it takes depends on your device and the size of the file.
Free, without an account
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
MP4 to M4V: what to expect
MP4 is a delivery format: other tools sometimes need audio only, a GIF, or a different container. M4V is recognised by Apple devices and by iTunes as video. MP4 is at home in sharing and uploading video anywhere; M4V is the usual choice for videos for Apple devices and iTunes.
The defaults suit most files. Under Options you can lower the resolution, trade quality against file size, remove the sound and trim the start and end. This is demanding work for a browser: a long or high-resolution file can take several minutes, and your device does all of it, so keep the tab open.
The conversion uses your browser's own video and audio codecs (WebCodecs), with hardware acceleration where the device has it; the file is read from disk as it goes and can be up to 2 GB. Where the browser lacks a codec, the page falls back to the compatibility engine. A video over 500 MB cannot be kept at full quality in browser memory; choosing a lower resolution or quality under Options lets it fit.
MP4 vs M4V
M4V
M4V video
M4V is Apple's name for an MP4 file, used for movies and TV shows sold through iTunes and for video prepared for iPod, iPhone and Apple TV. Files from the iTunes Store can be copy-protected, which only Apple's software plays. Unprotected M4V files are MP4 files and open nearly everywhere.
Opens in iPhone, Mac, Apple TV, QuickTime and VLC; most players accept it as MP4

Questions
Are my videos uploaded anywhere?
No. The MP4 to M4V conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Does converting MP4 to M4V reduce quality?
It depends on what is inside the MP4. When its video and audio are already in a form M4V can hold, they can be carried over without being compressed again. Otherwise they are re-encoded, which costs a little quality. Under Options you can favour quality or a smaller file.
Can I convert several MP4 files at once?
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
How do I convert MP4 to M4V on Windows, Mac, iPhone or Android?
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the MP4 file, press Convert and save the M4V. There is nothing to install.
Is there a file size limit?
Yes. Files up to 2 GB are accepted, and a video over 500 MB needs a lower resolution or quality chosen under Options so the result fits in memory. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
