wish formatting of paragraphs work as this will be convuluted all mashed together. The file i looked at has it's resolution reduced from 2084 x 2700 to 1313 x 1700. Alos, the dpi went up from 72 to 96, both are 24bit depth. So, they are reducing reso but then increasing dpi which doens't make sense. the file is 1/3rd the size give or take. A good thing: it strips some meta data in the file that could be mildly identifying. the vertical and horizontalreso being 72 vs 96 is a bit weird and can't really be true, if the resolution is lower. If they were smart and want to save some space, color depth is a great way to go. You don't need billions of colors or high reso when most people are using tiny little phone screens. your eye can only see down to 1/10th of a mm on average from some specific distance to make a conclusion like that. once far enough away or if screen is small enough, you cant tell between 1080p and 4k, for example. they eyes simply cannot resolve the difference at some point.
