How to perform Image Upscaling to very High Resolution


I searched in internet i did not find a easy or a best method to upscale image into high resolution. Can you please help to to simple upscale images without the data loss.

For example i want to upscale 1920 x 1080 image to 3840 x 2160 resolution image without data loss…

Thank you,

Why are you worried about data loss?

Have you tried – or considered – anything specific?
