MKV2MP4 is a fast video converter software that can convert MKV files to MP4 format, enabling compatibility with more devices. The software works through a queue system, allowing the conversion of hundreds of files in one go.

One of the things that stands out about MKV2MP4 is that it gives users the ability to configure the output settings to either achieve perfect compatibility or the fastest conversion speeds possible, depending on your needs. Keep in mind that if you choose the faster setting, your resulting files won't be playable on all devices (although most will be fine).
One of the best things about this software is that it doesn't require video re-encoding, making for a much speedier conversion process. Additionally, the resulting videos will have the same high-quality as the original source file. It's worth noting, however, that while most subtitles are supported, some players may not display them properly. To learn more about this feature and others, be sure to check out the F.A.Q. section of the software documentation.
