Converting video files for free is extremely easy, especially in the world of open source software. While there are a lot of options out there, almost all of them are plagued with ads, downloads, and are generally very ... uncomfortable ... to use.
I use, and recommend others use, ffmpeg to accomplish this task (there are loads of other options out there, but ffmpeg is what I'm used to).
ffmpeg is very simple to use if you're just converting files from one format to another. Simply open a command console and use the following command:
ffmpeg -i yourfile.input youfile.output
Of course replacing "yourfile.input" for the file you want to convert, and "yourfile.output" for the file you want to convert to.
