Video conversion
Convert WebM to M4V
WebM is a web video format used by browsers and Android apps, while M4V is Apple's own video format, used by Apple's media apps and devices. To convert, open the WebM file in a converter and export it as M4V. Doing this on your own computer means the video never has to leave your machine.
All 2,748 conversions verified on macOS, Windows, and Linux against the shipping release, this one included. Every conversion runs entirely on your own computer.

How to convert WebM to M4V

- Choose M4V as the output format.
- Convert. The M4V file is written next to your original, and nothing leaves your machine.
WebM vs M4V: what actually changes
| WebM | M4V | |
|---|---|---|
| Plays in web browsers | Yes, natively supported by most browsers | No, needs specific software or an Apple device |
| Plays on Apple devices (iPhone, iPad, and more) | No, not natively supported | Yes, built for Apple's media apps and ecosystem |
| File size | Smaller, efficient compression tuned for streaming | Similar, sometimes slightly larger for the same quality |
| Quality | Good, lossy compression | Good, lossy compression, comparable at similar bitrates |
| Metadata (title, chapters) | Minimal, not really designed for this | Yes, supports title and chapter metadata the way Apple's media apps expect |
When to convert, and when not to
Convert WebM to M4V when you want to watch a web video in Apple's own media apps, or keep it in a media library on a Mac or iPhone.
If the video only needs to play in a browser or on Android, keep it as WebM, since that's the format most web platforms already expect.
Why not just use an online converter?
Most WebM to M4V converters you find online ask you to upload your video first, process it on their server, and send it back, which means your footage sits on a stranger's machine for a while, even if it's just a home clip. Converting on your own computer with Morphjet skips that step: the file is read, converted, and saved locally, and it never touches the internet.
Questions
Does converting WebM to M4V lose quality?
There's a small lossy re-encode since both formats compress video, but at a reasonable bitrate it's hard to notice on a typical screen. If you still have the original source, convert from that rather than converting a WebM twice.
Will M4V play on Windows?
Yes, but it's less common there. Apple's own media software opens M4V fine on Windows too, but you'll likely need it installed since M4V isn't as universally supported as MP4.
Is M4V basically the same as MP4?
Very close. M4V is Apple's own variant of the MP4 container, mainly used for content bought through Apple's media store. Some M4V files include copy protection, though a video you convert yourself won't have that.
Can I convert WebM to M4V without uploading it anywhere?
Yes. A desktop app like Morphjet converts the file locally on your computer, so the video never leaves your machine or touches someone else's server.
Does the converted M4V keep the original audio and captions?
The audio track carries over. Captions depend on how they were stored in the WebM, so if they're a separate subtitle track, check that your converter carries it into the M4V rather than dropping it.
