Convert, compress, edit & download 4K videos at the fastest possible speeds.

Since 4K televisions became more common in 2014 more and more videos have been shot in 4K natively. This higher resolution has become more popular in the past few years and with that, more people are converting 4K videos into more manageable formats for use on devices like iPhones. Native 4K video takes up too much space on mobile devices and hard drives and many 4K videos are not even compatible with video editors due to format conflicts. The only options for this type of problem are to compress video sizes & video formats, edit the video clips down or adjust video parameters accordingly. This can be a very time-consuming job as many converters do not function the way that MacX Video Converter Pro 6.3 does.

User Experience

Using MacX Video Converter Pro is very easy to use. There is no set-up to complete when you start up the app. You simply drag media files that you want to convert into the dashboard and then you select the output profile you want to use. MacX Video Converter has many different profiles preset, but you can also customize the settings to suit your video needs. Once you make your selection about output, you click on ‘Run’ and then wait for the file to finish. To test it out, I converted a 2-hour and 25-minute long movie file to MP4. The file took approximately 10 minutes to convert. Max Video Converter Pro adopts high-quality deinterlacing technology and auto copy mode to ensure the original output video quality is maintained.
