HTML Optimizer Pro saves up to 10 or 15% of space on your Web pages by removing useless characters and tags. Although that seems to be a small improvement, the time which is saved when downloading is much higher as your client browser analyzes the pages in a more effective way. Your original pages remain intact for a later update. The optimized pages are created with the same creator of the original ones and are saved in a file named "Optimizer Output". HTML Optimizer Pro can handle pages with script blocks for the Java or another code without script errors.
