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.

Is there any limitation on MKV to MP4 online video converter? Well, it really depends.

  1. In most cases, free online video converter tools do have limitations on MKV file size (e.g. 100MB maximally), conversion minutes per day, conversion time per file, or concurrent conversion number, one or more of different degrees. Also, they might sacrifice the image quality due to their fixed settings on output video bitrate, aspect ratio and such. As to the converted MP4 file, you are confined to download within a certain of period, say, 24 hours from the time of upload. If you forget to download, the download link would become invalid and you need to do the same conversion again.
  2. Some free online MKV to MP4 video converters have pro-level products. If you wanna remove the limitation, you should pay for them by month or alike. But if you meet those who offer no solution for powering up productivity, you have to find an alternative.
