Best Video Compression Software to Reduce File Size by up to 90%

What's video compression? Generally speaking, it's a process of encoding a video file in such a way that it consumes less space than the original file and is easier to transmit over the network/Internet. With the advent of a new era of oversized 4K videos and the increasing demands for uploading 4K videos to online, sending by email or instant messagers, playing on mobiles, storing in limited space and so on, video compression has become an inevitable topic. For that, users are starved for a piece of decent video shrinking software to reduce file size without losing quality.
