MetaFox is an application for Windows that allows converting video files to MKV format in an extremely simple way.
To do the conversion just drag the file, or even a folder to the program's interface and it will perform the conversion. Converted videos can be found in the same place where MetaFox was run.
Currently, the software supports HEVC, AVI, MOV, MP4, MPG, FLV, RMVB formats, among others.
