MKV is a well-educated container format that can incorporate video, video and subtitles into a single file, so people love to backup DVD/Blu-ray movies and TV series to MKV themselves with MakeMKV or HandBrake, to prolong the life of original discs or digitize disc contents to build home theater. As is expected, there're a broad range of MKV sources online that moviegoers can free download with ease.
MKV, a nice container to hold movie data indeed. However, its bad compatibility for mobiles and TVs gives rise to converting MKV to MP4. Online video converters scatter here and there in browsers. With no third-party software downloaded and installed, those freebies enable MKV owner to convert MKV to MP4 on the web simply in clicks by:
Visiting free converting service online -> selecting .mkv file -> defining .mp4 as target format -> choosing quality or resolution if it's available -> doing .mkv uploading & converting -> downloading .mp4.

Step 1 - Open and Choose Right Module
Launch VideoProc. Click the first "Video" button from left to right to enter into "Video Processing" control.
Step 2 - Add MKV at Any Size and Amount
There's no limit to the MKV file size, video length and number of loads. You are free to input MKV (HEVC/H.264) video, one or more in a folder, into the software by clicking "Video (Folder)" button on the top menu or directly dragging & dropping.
Step 3 - Choose an MP4 Output Format
Just like MKV, MP4 is also a container format, which may hold different codec combination of video and video. Here VideoProc provides three MP4 options to select under Video profile list at the bottom: 1). H264 MP4; 2). HEVC MP4; 3). MPEG4 MP4.
By putting the mouse on the MP4 option, you will see a mini-window showing some video audio information and whether it supports hardware acceleration (HWAccel). Obviously, they three MP4 outputs keep the same audio codec, sample rate and bitrate while varying from each other by defining different video codec and frame rate. Also, they maintain the same resolution and aspect ratio as original. If you want to custom either of them, double click the MP4 option to do so.
Note: As a video converter and editor, VideoProc also features cutting, cropping, rotating, subtitling, splitting video and merging unlimited number of MKV videos into one MP4. You can do those edits after choosing output format.
Step 4 - Start the Conversion
With hardware acceleration engine checked and enabled automatically by VideoProc, you can begin the MKV to MP4 processing by tapping "RUN" button. Then a progress dialog will show up to represent you the speed and time. You can stop the conversion at any time or order the software to shut down computer when conversion is completed.
