4K is horizontal display resolution in the order of 4,000 pixels. There are several different 4K resolutions but the dominant 4K standard is 3840 x 2160 which is also known as 4K UHD. With so many pixels, no doubt 4K videos are very large in size.
Now, to reduce the size of a 4K video, you can compress it and save some space on your disk. There are several methods to compress the 4K videos. One method is to convert the video to the x265 format which is a High-Efficiency Video Coding video compression format that takes significantly lesser storage space as compared to x264 format. Another method is to tweak the video properties (bitrate, resolution, profile, level, encoding, etc.) in order to reduce its size.
When it comes 4K compressor software, there are not many options and most of those software are paid. But, still, here I managed to cover 5 free video software which you can use to reduce the size of a 4K video using various tactics.
