I'm intrigued. How would you accomplish this?
Any JPG outputting software I use asks me for a quality setting when I save as JPG. As such, it automatically re-calculates the JPG compression when you save, regardless of whether you changed anything or not.
I'm not being argumentative, I'm just curious
