Some, such as Online Video Converter and CloudConvert, are web-based tools that you can use if you have an internet connection. With others, such as Freemake Video Converter, MPEG Streamclip, and Any Video Converter, you'll need to download software on your device.

If you want to play MKV files on your iPhone, you'll need to download an external media player such as VLC for iOS as the built-in media player in Apple devices does not support MKV files.
