I like how it works. I've tested many different formats, and it works great! I like how it also will not compress something if the size is going to be larger than the original. I also tested from internal and external drives and it seems to work great! It puts processed images in the original directory that they came from which is nice. I think it would be cool to have an option to have a directory of choice that all processed images go to and I would like the option to add them to the program but then to process them when i want instead of having it do it automatically. (the automatic part it nice, but it would be nice to have a manual option to convert it too). Otherwise great app!

The program works. But I cannot open any images from my external hard drive, nor drag and drop them into the program. I first have to copy the image to my internal home drive and only then can I drag and drop it. With "Browse files" you will only find pictures on the internal drive. Now for compression: With the "Lossless" setting, the file size stays pretty much the same. Only when I switch the switch to "Lossy" does the program compress the image file for me. In my case from 13.2 MB to 2.8 MB by a good 79%! When I then compare the two images, I see no difference on my screen.
