Complete Guide: How to Convert MKV to MP4

MKV files are a great way to store your videos, but what if you want to watch these videos on a device that doesn’t support MKV? Well then you’re in luck because this blog post will teach you how to convert MKV files into MP4 for easy viewing.

Before we begin, let’s look at the various benefits of converting MKV to MP4 in further detail.

Why Convert MKV to MP4?

There are two main advantages to switching the format.

The first and probably most important reason you would convert MKV to MP4 is for compatibility. There are some devices or programs that don’t support the MKV container. Converting MKV to MP4 makes watching and editing your videos on a wide variety of devices much easier.

Other formats like WMV, AVI, MOV and 3GP also have this function but none work quite as well as MP4. If you convert your video from MKV to MP4 before transferring it to your device then you can be sure that it will work perfectly rather than having compatibility issues.

Secondly, converting MKV to MP4 just makes sense. An MKV file might take up a lot more storage space than an MP4 file. MKVs are usually uncompressed and typically contain the best quality, while MP4s are compressed to save storage space. If you convert your MKV file to MP4 then you might not only save yourself a lot of storage space but also might avoid experiencing lag.

Now that you know why it’s a good idea to convert MKV videos into MP4, let’s get down to the nitty gritty and talk about how you can actually go about doing this yourself.

Q: When I’m going to edit the MKV video, why can’t I click certain options under “Edit”?

Q: The MP4 file cannot play on my device after conversion.

Q: I convert MKV to MP4, but there is no audio on the new MP4 file. What went wrong?
