How to generate LUT files to use in Post Process?

Hello All,

Myself Rohan,
I am using UE4 from last 1 year. Have just one query. While working on post process for one of my shot, I came across LUT files. can someone tell me , from which software or the process to generate LUT file as .png to use in Unreal.
I went through lot of online stuff. There are few free LUT files for download. But its already generated. Is there any way to create these files as i want ?

Thanks & Regards
