Compress 4K UHD Videos on Windows 10 without Losing Quality

4K resolution, also known as 4K, is one of the new trendy tags coming into people’s sight in recent years. It’s a newly-emerging resolution standard for Ultra HD, which provides with the ultimate visual experience. However, when we try to play, edit or share online downloaded or camera/camcorder captured 4K video, we find that it is not less easily accessible and compatible than 1080p video. This enforces users to reduce and compress video size to make the video smaller for different reasons. For example, to allow the videos to be uploaded to web like YouTube or sent via email to family or friends, you have to make video size smaller than 2GB for YouTube and 25MB for most email system. Another simple example, you will need to pay extra $100 to get an iPhone 7 or iPhone 6s with larger storage. So, in the final analysis, is there any video size compressor or way to compress and reduce video file size from 4K UHD MP4, MKV, AVI, MOV etc on Windows 10?

Windows Movie Maker is a professional compressor claiming that they can reduce video file size. However, with the release of Windows 10, Windows Movie Maker is no longer available. Here is an alternative that works equally well to make large files smaller on Windows 10, UFUSoft Video Converter. This file compressor can significantly downscale 4K video to 1080p, 4K video to 720p, 1080p to 720p, shrink the file size without losing any quality on Windows 10 by converting the video to smaller formats like FLV, WMV, AVI, RMVB etc, adjusting various video audio settings, cutting unwanted parts etc. I have used it to compress a MP4 video which is 108MB. After compression the size is 30.1MB only while I can’t identify any quality loss. It can reduce up to 70% of the file size from 4K UHD. Mac users please turn to UFUSoft Video Converter for Mac.
