You need go to File > Add Video Files and to browse for your MPEG video. Add your video on Leawo Free 3 GP Converter. Usually the output file is selected to be 3GP by default and you must only press the conversion button from the right part. If the output is not selected by default into 3GP, down on the program overview are the output settings where you can select the output folder, video and audio quality and the output format.
