JCH Optimize automatically applies several front end optimizations for faster download speeds for your Joomla!
JCH Optimize PRO is one of the most popular plugins to speed up Joomla latest versions. Compresses and combines .css and .js files, as well as some types of images, turning them into fast-loading sprites. The full version also provides asynchronous loading of java scripts and additional features to compress and speed up the loading of pages.
