With Flash Optimizer you can:
Reduce SWF file size without FLA source
Flash Optimizer optimizes 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. Your SWF files will weigh less, load faster and won't lose their quality!
Choose the best SWF compression options
Flash Optimizer provides the simplest user interface with two tabs: "Compress one file" and "Compress many files" for better optimization process management. Flash Optimizer offers several compression settings so you can achieve better results even if you don't know a thing about Flash!
Preview and compare
SWF Info dialog box to the right of the file preview shows all the detailed information on the structure of the movie: size of shapes, images, morphs, sounds, fonts and other elements. You can compare the size of the movie and its elements before and after compression by clicking "Preview Compression" button. Optimize Flash files in seconds!
