Is Possible to Convert iPhone 4K Video to 1080P Online?

I don’t recommend you to use the online 4K to 1080P converters. At least for now, I haven't found any good free online tools that can work well. For example:

  • HDconvert.com- It offers the output option- Full HD 1080P, but the options that higher than 1080p are not free. You have to upgrade to the Premium version. Even if you select 720p, the output file will come with a watermark.
  • Zamzar.com- It lets you convert 4K video the preset for iPhone, but there are no options to change the video resolution. Moreover, the maximum file size of the input 4K video can’t exceed 150MB.


This post mainly discusses how to convert 4K to 1080P iPhone. If you want to convert 4K video to 1080P in a convenient and effective way, Cisdem Video Converter is the best choice for Mac users, which will bring you a fabulous experience as described in the above-mentioned steps. If you are more inclined to complete the task for free and faster, try the iMovie, Handbrake, or VLC.

    The efficiency of converting 4k files on a mobile phone is very low, and it even crashes when the processing reaches 80%. I prefer to do it on the computer first, and transfer the converted files to iPhone.
