I would like to know if anyone can suggest a free app for iPhone or iMac that can take an old blurry jpg photo and make it more clear? I've tried downloading a couple, but then they insert watermarks and want you pay/subscribe to actually update your photo; so not technically free.
I have one photo of my son as a child that I'd like to make less blurry, as part of a collage, because he's about to graduate from college next month. Any help is appreciated!
