The Matroska Multimedia Container (MKV) is a free, open multimedia format for video, audio, images, and subtitles suited for streaming. It was released in 2002, and its filename extension is .mkv.


The MPEG-4 Part 14 format, better known as MP4, is a multimedia container used to store digital audio and video. It can store other kinds of data, like still images and subtitles.

Frequently Answered Questions

Are MKV files bigger than MP4 files?

Yes, MKV files are usually larger than MP4 files.

The reason for that is that even though they are both containers, MKV files encapsulate larger amounts of data than MP4 videos.

MKV counts with other features that MP4 lacks, and it can contain multiple video, audio, and subtitles tracks. But MP4 videos only store a single track of each type of media supported by the format, which makes the files smaller than MKV.

Does renaming MKV to MP4 work?

No, it is not. You can't convert MKV to MP4 just by renaming the files. You can't convert any file to another format by changing its name. It doesn't work, and it's a loss of your time.

If you want to convert any file to other formats, you have to install conversion software on your device or use an online converter. It's not possible otherwise.

Does converting MKV to MP4 makes the file lose quality?

No, it doesn't. Since MKV and MP4 use the same video codec in most cases, the only thing that needs to be converted is the "wrapper." Thus, one container (MP4) replaces the original (MKV), and the data remains intact.

That way, both the video and the audio maintain the same quality. But if the MKV video uses a codec with higher quality than MP4, in that case, the video will lose quality during the conversion.

Other things you will lose are the multiple video, audio, and subtitle tracks if any. MP4 only stores a single track of each, and the extra ones will disappear during the conversion.

Can you convert MKV to MP4 on Mac?

Yes, you can, but you must install a conversion program to convert MKV to MP4 using a Mac. Mac OS doesn't perform file conversions natively, and for that reason, the software is necessary.

But you can't avoid looking and installing new software using online converters like Convertr. Our platform is reliable, fast, and easy to use. It's free, and you can start using our tool once you enter the site!
