This is expected behavior. All png files in the built app dir are optimized for running on the actual device, specifically, the red and blue components are swapped and the alpha channel is pre-multiplied (whatever that means). The output is non-standard PNG image that is LARGER than the original. See this article for more info: http://iphonedevelopment.blogspot.com/2008/10/iphone-optimized-pngs.html
