but you're changing the actual attributes of the file...I don't
consider that compression...compression to me would be taking the
same identical file and making it a smaller filesize without changing
it's physical size or quality. Optimizing is more what you are
describing and anytime (I'd hope) you decrease an image's physical
size or quality of course you'll get a smaller filesize, some
programs do it better than others. As you pointed out PS is great at
it...some other popular programs are not so great at it.
