Free 3GP Video Converter 

Free 3GP Video Converter is a modern and powerful video conversion tool that supports most video formats available. These formats include AVI, MPEG, WMV, MP4, MOV, and, of course, 3GP, among many others. The program can also be used to extract the audio from your video files and save it as an MP3 file in the bit rate of your choice.

The program's user interface is very simple and intuitive, and it includes several interchangeable and attractive skins. Besides, you can change the interface's language and choose among eighteen of the most popular languages worldwide. This tool supports batch processing, allowing you to add several source files for conversion and re-encode them in a single operation. You can customize the output file names by specifying a prefix, a suffix, and a separating character, and select whether to include the original file name and the current date or not in the new name. Unfortunately, Free 3GP Video Converter does not include a built-in media player for you to preview your source files, which is a common feature in this kind of applications.

As for the output format, you can set it very easily by selecting it from a list. The program includes a very good set of quality presets for each of the output formats supported. Those presets help you define your desired output quality, which you can also customize together with other output parameters, such as the video container, its codec, the bit rate, the frame rate, and the resolution, as well as the audio codec, the sampling and bit rates, and the number of channels. You can do this by opening a tool called "Preset Editor".

As you can see, Free 3GP Video Converter is a versatile video conversion tool which supports not only 3GP, but also a lot of popular video formats. It allows you to convert your video files - or extract their audio stream - in an easy, fast, and reliable way.
