Critical Path CSS Generator is a Free Online tool that automatically generates the Critical Path CSS for websites and builds a solitary minified CSS file by analyzing all the CSS files used by your website.

One of the most common reasons for slow loading of websites is the issue of Render-Blocking Resources or Code such as Scripts, HTML Imports, Stylesheets and more.

These Resources obstruct the browser from starting the page rendering process, delaying your First Paint that is the time duration between navigation and when the browser shows the first pixels on the screen.

Removing these render-blocking resources can cause your page to load significantly faster thereby improving your website experience and eventually your search engine ranking.

This can be achieved by optimizing Critical Rendering Path so that the display of content can be prioritized above everything else. In case of CSS, the process involves identifying the Critical Path CSS which is the actual CSS that is used for page rendering. The remaining non-Critical CSS can be loaded at a later stage as it is not concerned with the display of the page on the screen. Thus, you can speed up your website by placing the non-critical CSS at the end of the page and load it using some additional JavaScript.

This is precisely where Critical Path CSS Generator comes in handy. It not only identifies the Critical Path CSS for your website, but also places them into a separate file that you can download in minified or unminified form.

6. Download or Copy the Critical Path CSS file and Paste its contents in the ‘Head’ tag of your webpage. You must also move all the references to your CSS / JavaScript (JS) Files to a location just before closing the Body tag. In some webpages JS may be needed to render the fold content. If this is the case, you must ensure that only the references to CSS files are moved, whereas JS references are left in place.
