The bulk of my game's startup time is spent decoding PNGs via libpng. There are some alternatives to libpng like fpng[1], or alternate image formats like QOI[2]

These both exist because png is slow and/or complicated.

Most games ship textures in a GPU-friendly format such as DXT to avoid problems like this.
