Top Video Size Converter: Reduce Size of MP4 MKV 4K Video Up to 70%﹢

Posted by Estelle to convert video, Reduce Video Size | May 05, 2017

Usually, a video size converter is high-sounding so consumers believe that this application has powerful features that it clearly doesn't and most of the time isn't anything like they lead you to believe. Take Handbrake for instance. When you google "video size reducer" or "convert video to smaller size without losing quality", Google will show you the top results, among which two YouTube videos titled "How To Reduce a Video File Size By Over 90%! Without Losing Quality" will definitely draw you attention. You can't help wondering if this free video size converter can really shrink file size up to 90%.

I have the same feeling with you. Hence, I watch the 2013 uploaded YouTube video and get the operating steps. I use the method it tells to have a test in Handbrake 1.0.1 on my iMac (Yosemite). The result shows that I can only compress MKV (AVC) video to MP4 (H264) from 89.4 MB to 78.7MB with little quality loss. That's a big gap between propagation slogan and real test result. If Handbrake can really reduce video size up to 90%, my output file should be 8.94MB. So until now, do you still believe the advertisement?

In case you plan to change a video compressor, here recommends you a genuine application, which is 100% exactly what it claims or better.
