A lot of video or movie resources on the internet are saved in the MKV format. As a popular video format, MKV can not only keep a good video quality in the media file, but also save multiple kinds of data like audio tracks and subtitles in one single file. However, the MKV video format is not compatible on all platforms. For a lot of cell phone models, 3GP is the format that has the best compatibility. In order to play your MKV movies on these cellphone models, you need an MKV to 3GP converter to convert your MKV movies to the 3GP format and then transfer the files to your phone. So, in today’s article, we will take a look at some of the best MKV to 3GP converters, and see how to convert MKV movies to 3GP efficiently with these programs.

Part 1: Basic Knowledge About MKV and 3GP

Getting to know the two formats helps us to better understand why and when we need to convert the MKV videos to 3GP. So, before we get to the point of how to convert MKV to 3GP, let’s have some basic knowledge of the two media formats.

MKV, also known as The Matroska Multimedia Container, is a free, open-standard container format for multimedia files. As mentioned above, the format can hold an unlimited number of media contents like video, audio, picture, or subtitle tracks in one file. It is also a universal format for storing common multimedia content like movies or TV shows. However, the MKV video format usually doesn’t have a great compatibility for mobile phones.


When it comes to the most appropriate format for mobile phones, 3GP is no doubt the No.1 choice. As a multimedia container format defined by the Third Generation Partnership Project for 3G UMTS multimedia services, 3GP is supported by nearly all mobile phones. So converting MKV to 3GP can make sure that your video can be played on almost any smartphone model. Now let’s take a look at how to do the MKV to 3GP conversion.
