Free MKV to MP4 Converter is a simple application that lets you convert MKV files into MP4, MOV, and M4V video files. In addition, the program provides basic editing features that allow you to customize the original video and obtain the results you are looking for.

The utility opens with a clearly defined, modern, and easy-to-use interface. You will see what the program is capable of at a glance, since all functions are viewable and accessible from the main window. The only hidden option, selectable from the drop-down menu, refers to the selection of the output video folder, the image format of the snapshots you may take, and the destination folder of your shots.

The conversion process requires you to take a few simple and intuitive steps. First, you need to import the MKV files you want to optimize – the procedure supports both the convenient drag-and-drop method and the classic browsing for files from within the application. You can add either one video at a time or entire folders of files, so that your batch importing and conversion needs are fully supported. Once the list of files to convert has been defined, you can fine-tune the source video files by adjusting sensitive video and audio parameters, as well as apply a series of ordinary yet handy video edits. Therefore, you can merge multiple files into one larger video, trim scenes, crop the displayed image to custom sizes, add watermarks, as well as tailor the image contrast, brightness, saturation, and hue. The volume can also be adjusted in terms of loudness, yet the sound can't be replaced with a different audio track.

Once all settings are done, you just need to enable the conversion. The process can be followed while in progress, as the app provides you with a real-time preview of the conversion process and gives you information regarding both the elapsed and the remaining times in relation to the converted section of the current file.

In short, the program offers a free and straightforward solution to optimize MKV files for playback on portable devices. The conversion runs well and the editing features make the program a perfect choice for home users.
