YUI Compressor

YUI Compressor is a tool used by web developers to optimize website files, specifically JavaScript and CSS. It reduces the size of these files by removing unnecessary spaces, comments, and other non-essential code, which helps your website load faster and perform better. By making files smaller, YUI Compressor improves user experience and can also reduce bandwidth costs. It is typically used during the website development process to ensure that the final site runs efficiently without altering its core functionality or appearance.
