Resize is unpredictable
Not sure what’s happening here. I choose a resize option, and it seems to ignore it. My original file is 4288x2848. I chose 2048x1536 and although the file size was reduced drastically, there was no change in the dimentions of the image according to Finder. I tried again with 1600x1200, and it gave me a file that is 3200x2124 according to finder.
I give it two stars because it does indeed reduce the file size while preserving image quality. However, I can’t imagine using this program for reliable image resizing.
