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 a 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.
The Online MKV Compressor by Clideo will help you do that with one click and completely online. You can compress any amount of videos a day.
How to compress MKV files without losing quality
Add an MKV video
Choose a video from Mac, Windows, Android or iPhone. You can also select it from Google Drive or Dropbox by clicking the blue downward arrow. If you want to convert your video from YouTube — you can do that too! Just paste the URL to the box in the dropdown menu. You can add a file up to 500 MB.
Wait a little
Wait a few seconds or minutes while the tool is compressing your video. It depends on the file size. We will compress it as much as possible to remain the quality.
Download your video
Your video is ready to be saved! The tool shows you the initial size and the compressed one so you could compare. Download it back to your device or to cloud storage.
