Pretty good but…
For my usage, I only work with the compression and file type conversion features. I’m extremely happy with the compression functionality. The output size preview is a nice touch. The only thing keeping this from being 5 stars is the problems I have with file type conversion. There is no way to specify the output dimensions when changing the file type. I’ve found that these conversations also greatly reduce picture quality. I assume the app is using lossy conversion. I would like the ability to control the output dimensions when changing file type and the retained quality. It would also be nice when compressing images to choose the output file type. I also noticed that in one instance, the app overwrote the original photo. I think the top and bottom save buttons act differently here. If a future update fixed these issues, I would gladly increase my rating.
