How to Convert MKV to 3GP (Offline & Online)

The ubiquitous MKV format is favored for a reason - it's versatile, has multiple audio and subtitle tracks which is ideal for storing movies and DVDs, and is high quality.

You may have downloaded some MKV files from the internet, however, only to find them unplayable on your mobile devices. The truth is, although MKV is increasingly popular, it’s not suitable for watching over devices where the storage is limited and the playback support is weak, such as mobile phones. Therefore, in cases like this, it’s best to convert the format to a native mobile video format such as 3GP. This will result in a small file size and low quality, but it's just right for the small screen of a mobile device.

Next, I’ll show you easy-to-use MKV to 3GP converters to help you handle the conversion with ease. Read on.
