With the popularization of 4K, users can now enjoy videos and movies with staggering vivid details. While 4K is relatively new, users inevitably find that devices supporting 4K are rather limited and sometimes a special 4K video player is a must but which may cause platform incompatibility issue.

Here we introduce you top three 4k converter software to help you convert 4K to 1080p, 720p and other more commonly-used formats or upconvert HD videos to UHD for higher image quality and better enjoyment on 4K TVs or so.

Warm prompt: The internet is rife with many so-called 4k 2160p video converters. Some can only downscale 4k to HD 1080p videos for wider compatibility with HD TVs, smart phones, tablets, etc. But hardly can they cope with HEVC codec in 4K UHD videos, let along handling the HD to 4K upscaling. It's also disappointing when you find some tools perform a lengthy 4k video conversion because upconverting 4K UHD videos is much CPU consuming. Given speed, HEVC compatibility, and quality into full consideration, here we introduce the best 4K 2160p video converter software.
