MKV Compressor – Online & Free

MKV, the Matroska Video format, is an open multimedia container that can hold practically unlimited video, audio, and subtitle tracks in a single file, along with chapters and metadata. That flexibility made it a favorite for high-definition movies and feature-rich releases. The catch is that all those tracks and high-quality streams add up, so MKV files are often among the largest on a drive.

When an MKV file is too big to store or share, Movavi compressor online lets you compress MKV online without installing anything. It’s free, the entire process runs in your current browser tab, and it takes three steps: upload your video, choose your settings, and download. You can reduce MKV file size for media servers, cloud storage, uploads, or freeing up disk space. This free MKV compressor keeps the image sharp while cutting the size significantly, and it manages long, high-resolution films with ease. With control over resolution and bitrate, Movavi is a dependable MKV size reducer online that lets you shrink an MKV file without sacrificing the detail you want to keep.
