Are you ready to be compliant to Google Core Web Vitals? JSpeed is the professional solution to speed up your website performance and make Google happy increasing the PageSpeed Insights and GTMetrix rank in a snap!

Google rolled out the new "Speed" report within the Google Search Console to confirm that the speed factor is more and more important for the ranking of a website.
The Google PageSpeed score assigned to your pages is now crucial, a score of 90 or above is considered fast, and 50 to 90 is considered moderate. Below 50 is considered to be slow.

JSpeed increases performance of your website by applying automatically several improvements as suggested by Google PageSpeed best practices. By installing the plugin you can reach up to a doubled score during the Google PageSpeed and GTMetrix test.

JSpeed is the most powerful Joomla performance plugin that implements unique technologies such as Adaptive Contents™ that makes it possible to generate a lightweight version of the website to dramatically raise up the page speed score without losing website functionalities.

JSpeed functionalities include:
•Scripts minification: Javascript can be minified to reduce the total scripts size and save bandwidth

•Stylesheets minification: CSS can be minified to reduce the total CSS size, save bandwidth and extract the 'Above-the-fold' CSS

•HTML minification: The HTML source code can be minified to reduce the total page size and save bandwidth

•Auto configuration and integrated Google PageSpeed™: The plugin is capable to find the optimal configuration automatically and integrates the Google PageSpeed test

•Defer and preload of assets: CSS, JS and Web Fonts can be loaded in defer, async or preload mode

•Lazy-load images: Images and iframes that are out of view can be lazy-loaded only when the user scrolls down the page to display them

•Lazy-load HTML elements: Heavy HTML parts that slow down the LCP can be easily lazy-loaded

•Images optimization: Large images can be rescaled, resized and optimized on the fly to dramatically reduce the page size and bandwidth

•Assets removal: It's possible to remove CSS/JS files and Fonts to avoid the loading of unnecessary resources

•Htaccess optimization: A series of optimizations can be applied to the htaccess file in order to leverage the browser caching

•Combine images: It's possible to generate a single container image for multiple backgrounds applied through CSS

•HTTP/2 optimizations: JSpeed works with HTTP/2 compatible servers to enable server push

•CDN support: Links for all assets can be automatically rewritten to point to your CDN domain
