iResizer 3 4+

This app does remarkably well with modest adjustments, such as fitting an odd sided photo to the next largest standard dimensions. It has more trouble when you need to make a very large adjustment, and that sometimes results in some strange stretches of people and objectsl There is a simple tool which lets you select areas not to be stretched or compressed, and that often can result in a usable image, even when you need to make a big adjustment.

This worked perfectly to create square photos. I used it to take a book cover graphic that’s rectangular, and I needed a square one for ACX audio book format,so I thought—for the price—this is a way better deal than bothering my graphic designer (and paying them) and after one false try, I got what I needed! Oh wonderful!! There is an informative help file online, (and I’m sure I’m not using even half of the well thought out functionalities of this app) but all you do is click the green button to stroke over the parts of the file you don’t want all stretched or distorted. Leave the other background parts alone so the app has room to work, and use the preset sizes—and you are good to go! Awesome little app! Thanks for making it. :) #love Will tell all my author friends!

Not sure why I had so much trouble learning to use this. The UI isn't the most intuitive for me. But once I stumbled on the ins-and-outs, mostly by pushing buttons to see what happened, it is fast and easy to use. I can enlarge or reduce, and quickly.
