Why compress MKV file

MKV is an open multimedia container format also known as Matroska Multimedia Container. It can store audio, video, and text in one file.

You probably need to compress your MKV video to share it to social media like Facebook, Twitter, or Instagram. It'd be also useful if you want to send it through email as all such services have a size limit, for example, Gmail allows only 25 MB for all the files in one email message.
