What is the fastest way to convert MKV to MP4?

The fastest way to convert MKV to MP4 is through an online converter. Some of the best ones include CloudConvert and Veed. You’ll just have to upload your MKV file to the site. And select the option to convert it to MP4. You may then download the converted file after the process finishes.

How to convert MKV to MP4? 7 easy ways

Just a heads up before we get started.

The first 4 ways here involve installing an app to your computer. While the last 3 are websites where you can upload and convert your MKV file.

Now, if you’re going to ask whether it’s better to use an app or a website…

The truth is, both methods are fine.

But one advantage of using an app is you won’t need to upload your MKV file. And then download it as soon as it’s converted to MP4.

The only thing you need to download and install is the app itself.

If you opt for the converter website, though…

You won’t need to install anything on your computer. And it’s an advantage if your device doesn’t have much app storage space.

But the actual conversion of MKV to MP4 is easy. And depending on the file size, it should take anywhere from a few seconds. To a few minutes.

So it’s really up to you whether to use an app. Or a website.

And with that, let’s get started.

#1: VLC Media Player

3.5 billion. That’s the estimated number of times the VLC media player app’s been downloaded.

It has been around for about 2 decades now. And it’s still among the best and most versatile media players available. Able to play a wide variety of file formats.

And it’s a great app to have on your computer. Especially since streaming services like HBO Max and Apple TV won’t always work on your device.

So with VLC, you can’t watch downloaded files offline without hassle.

However, it isn’t just a media player. Because you can also use it to convert files from one format to another.

How to convert an MKV file to MP4 using VLC

Step #1: Download and install VLC to your computer. It’s free. And available for Windows, Mac, and Linux.

Step #2: Launch the media player on your device after installation.

Step #3: Click Media. It’s on the top left of your screen.

Step #4: Select the Convert/Save option.

Step #5: A window called Open Media should pop up. From there, click the Add button.

Step #6: Look for the MK4 file on your computer. Then select it and click the Open button.

Step #7: Click the Convert/Save button.

Step #8: A new window called Convert should appear. Look for Profile. And click the dropdown menu. Then select Video – H.264 + MP3 (MP4).

Step #9: Still on that same window, look for Destination File. Then click the Browse button.

Step #10: Select the folder or drive where you want to save the converted file. Then create a file name and click Save. This will take you back to the Convert window.

Step #11: Click Start to begin the conversion process. And wait for it to finish. The progress bar should let you know when it’s done.

After it’s finished, you may access the converted file to where you saved it.
