Video converter is probably the most popular software in the market. You will find hundreds of such free video converting tools by just typing the keywords on Google. It is easy to find a converter that works well for you.
One thing you need to know is that not all MKV converters are created the same. There are some reliable media converters which will keep original high quality while some may reduce the quality significantly. What is even worse is that some freewares come with adwares or any extra plugins. Your computer maybe filled with pop-up ads time from time and runs slowly after installing them.
So you should learn the programs carefully before you installing them. As a software technician, I constantly download all kinds programs to test from my computer.
