Free MP4 Video Converter 

Free MP4 Video Converter is an application which helps you convert video and audio files to MP4, AVI and WMV. The program supports popular media formats as source files.

This tool provides a simple interface; you are allowed to change the background choosing among predefined images. The converting process follows few main steps: you select one or multiple files and choose the target format. The app shows you the formats compatible to a great number of gadgets; this will help you in case you don't know which ones are supported by each multimedia device.

What's more, the output files’ properties can be adjusted taking into account customizable parameters: frame, layout size and bitrate for video files, and sample rate, format, mono or stereo channels for audio files. Additionally, you can create your own presets and add them to predefined profiles for later use. You can save the output files with supplementary information like Artist, Album, Title, etc.

However, this tool is not perfect. It doesn’t have a preview option and the main window can't be maximized. Regarding the Help section, this option is not available within the program; still, you can have a look at the small guide hosted on the developer’s official site.

To sum up, this program comes with many settings, which make it good for a free tool. I want to emphasize that I didn’t receive any error message while testing. Yet, you should pay attention when installing the app; you may get yourself with three additional programs without your will.
