MkvToMp4 is a free portable multimedia conversion utility for Windows which allows you to convert a very large number of audio and video formats to MP4 audio and video formats (M4A, M4V). Batch conversion gives you the option of converting multiple files at once. Something that’s far more interesting about MkvToMp4 is that it can convert MKV videos into MP4 without encoding, presuming that the original video is using the H264 codec.

The fact that this free MKV to MP4 converter can convert MKV to MP4 videos without transcoding files is the reason for its name, despite of the fact that MKV isn’t the only format that can be converted. Video and audio tracks which are using different codecs will of course have to be encoded. All the way at the top we have a toolbar where for the most part we have options for managing files on the list down below.
