ImageOptim

in a previous post I discussed using ImageOptim to reduce file sizes for websites. I also tried it on some apps. Our apps use lots of images and sounds so they are quite large. The table shows the reduction in size when I used ImageOptim and turned off PNG compression in Xcode. You need to turn off PNG compression because Apple uses their own compression method that is supposed to optimize display time but has a side effect of making file sizes larger. I don’t see any difference in display time, so I’ve opted for smaller file sizes.
