title: Do indexed PNG 8s use less memory when utilized by XNA
body: <p>I'm working on an XNA project and running into issues involving memory usage. I was curious if using indexed color PNG 8s vs PNG 24s or PNG 32s for certain textures would free up any memory. It definitely makes the app smaller, but I'm curious if when XNA's content manager loads them they somehow become uncompressed or act as loss-less images.</p>
