[enlarging photos and increasing pixels]

I need a very uncomplicated way to increase my picture size and increase pixels. Will Affinity be a simple program to use for this? I need to post good quality pictures (the ones I have are too small) and it must be super easy or I might fling my computer out of the window :wacko: I am new to mac and it is as much of a challenge as I can endure :rolleyes:

Hi, I have a 2012 mac pro and all I want is to enlarge pictures and increase pixels for my eBay photos. It has to be simple. Can infinity program do this for me. I have a note on my email page that says I need to update my browser but the response when I try is that the file is corrupted. It's a new laptop and just want to make certain that it won't affect the program.  So, again, I just need a size and pixel increase. Nothing fancy. Many Thanks, Debby
