Flash Optimizer is a powerful solution for anybody dealing with Flash, which reduces SWF files size up to 60-70% thanks to amazing algorithms of vectors, shapes, morphing, Z-buffer, fonts, sounds and other optimizations. Unlike any other similar software Flash Optimizer manages to optimize not only a separate part of your Flash movie, but the whole SWF, including curves, zero-objects, ZLib optimization and a whole lot more advanced techniques.
