Images are automatically resized and compressed (file size) on upload, but they shouldn't distort...

May be more a matter of the camera/phone. Used to get the same problem back in the days of real cameras, had to stand a bit further back and zoom in a bit to get rid of the slight distortion. Only really shows up on things that are round, you don't notice it on other stuff.
