What is MKV?

MKV (Matroska Multimedia Container) is a universal video file format that holds an unlimited number of video, audio, picture, or subtitle tracks in a single file. It’s often used for movies and TV shows because it provides lossless compression — which means better quality.

One downside to MKV files is that they’re usually pretty big, which makes it harder to send them or store them on your device. MKV video files also aren’t compatible with as many players as MP4; the most common players that accept MKV are Windows Media Player, VLC and DivX Player.

What is MP4?

MP4 is one of the most widely used video file formats. You can upload MP4 videos to popular social media sites like YouTube, Instagram, TikTok, Twitter and Facebook. Media players like Windows Media Player, VLC, QuickTime, iPhone, iPad and Android are also compatible with MP4 video files.

MP4s are popular not only for their compatibility with most devices but also for their ability to hold high-resolution videos without taking up much storage space. MP4 stands for MPEG4, and an MP4 file can contain video, audio, images and subtitles.
