MKV (Matroska) is the most common video container on the web. But is it possible to play MKV on iPhone without converting? Oh yes! This guide will show you the shortest way.

Watching movies on your iPhone has its own charm. Whether you are traveling or killing time in the waiting room at your doctors, your iPhone is always on you. You can always choose the most comfortable spot to cozy up and enjoy your favorite movie.

What video format does iPhone use?

iPhone supports MP4, M4V and MOV formats. This could be a bummer because when browsing internet, you will definitely stumble upon a format that isn’t one of the mentioned three. MKV is one of them.

Can iPhone play MKV or AVI?

iPhone supports neither MKV nor AVI files.

The most widespread solution is to find a third-party app on the AppStore that will play or convert the file. The problem with that solution is that these apps don’t stay up on the AppStore for too long and they are full of ads. Annoying.

There needs to be a simpler way to watch MKV on iPhone, and there is. WALTR 2, a macOS and Windows app, is the most reliable and time-efficient way to put MKV on iPhone.

Check out this screencast tutorial to see WALTR 2 in action:

Step 2. Drop your .mkv file into WALTR 2.

The movie is now on your device and you will be able to find it either in Videos or TV app on your iPhone.

MKV vs MP4 & MKV vs M4V

If you are curious about the differences between MKV, MP4, and M4V, I’ll lay down some basic foundations.

 It’s very important to clarify that the formats mentioned above ARE NOT file compression formats, but containers that include things like audio and video codecs, subtitles, and so on.

M4V is very similar to MP4, except the first one was developed by Apple to accommodate its products. When it comes to the MKV or MP4 battle, MP4 is certainly more popular and will be supported by more products without the need for conversion, but both support the high-quality H.264 video.

Bottom Line

I sincerely hope that our solution for how to play MKV files on iPhone will come in-handy. It’s an incredibly simple process that allows you to fully immerse in the iOS word without having to fear the file transfer process.

In addition, WALTR 2 is a truly universal app. The simplicity that you will experience when transferring MKV to iPhone is shared by other formats and devices as well. WALTR 2 is your transfer buddy. Use it. Enjoy it.
