This post will mainly talk about 4 4K video compressors, such as MiniTool Video Converter, HandBrake, FreeConvert, and VEED, to help you reduce the file size of 4K video, so you can easily upload it to social media platforms or send it to others. The general steps include importing the 4K video, adjusting compression levels, and starting compression.
What Is 4K Video
4K video refers to a video with 4K resolution. 4K refers to a horizontal display resolution of about 4000 pixels, which means excellent image quality and an immersive visual experience.
4K video is also known as Ultra high-definition (UHD) video, and the standard for 4K resolution in the video/movie projection industry is 4096 x 2160 pixels, whereas the dominant 4K standard for television and monitors is 3840x2160 pixels.
Why You Need to Compress 4K Video
- Large File Size: 4K video will take up a lot of your storage space. Some people even need to purchase a larger external hard drive to store 4K videos.
- Not perfect for sharing videos: 4K video files are typically large, making them prone to restrictions when uploaded to social media platforms or shared with others.

VEED is another online 4K video compression tool.
