MKV Video Compressor

MKV (Matroska Video) is an open-source container format that supports virtually any video and audio codec, along with multiple subtitle tracks. It's the preferred format for archiving movies, TV shows, and anime because it preserves everything in a single file. However, MKV files are often very large (1GB or more) and are not accepted by social media platforms, messaging apps, or most mobile devices. CompressYourVideo.com converts MKV to a compressed MP4 that you can share anywhere. During conversion, the tool selects the primary video and audio tracks and compresses them to your target size. Subtitle tracks are not preserved in the compressed output since social platforms don't support embedded subtitles.
