# PageCDN - Easy Speedup

## Free CDN

[PageCDN](https://pagecdn.com)'s free CDN accelerates delivery of opensource content, thousands of WordPress themes and plugins, 
fonts and more. It takes each resource separately and intelligently optimizes it using the best information available.

Instead of just replacing hostname with CDN hostname, PageCDN WordPress Plugin serves your static assets such as images, fonts, CSS or 
javascript files in the best way possible. For this, it takes each resource separately and tries to get its most optimized version 
from PageCDN using its Public CDN API. The benefit of loading resources through Public CDN is that such resources are most of the 
times already available in your visitor's browser cache saving some bandwidth and loading time.

Please note that loading resources from Public CDN reduces your CDN bandwidth cost as Public CDN is available for free.


## Premium CDN

If a resource is not available on Public CDN then you will need to optimize it using Premium CDN feature. For resources like your 
website images and commercial theme/plugin files, etc this plugin simply links the resources through PageCDN using PageCDN Private API, 
and gets you brotli compression, geographic delivery, HTTP/2 and other benefits that PageCDN offers.

Also, with PageCDN Plugin, standard CDN **setup is 10X easier** compared to any other CDN Plugin.


## Which resources are available on PageCDN's Public CDN?

[PageCDN](https://pagecdn.com/)'s Public CDN hosts the following type of content for free. Bandwidth from Public CDN is not considered 
for your CDN bandwidth cost calculation.
* Opensource Libraries.
* Opensource WordPress Themes.
* Opensource HTML5 themes.
* [Easy Fonts](https://pagecdn.com/lib/easyfonts) - A replacement of Google fonts with better caching and easy to use CSS font classes.
* [Patterns](https://pagecdn.com/lib/subtlepatterns) from Subtlepatterns.
* Opensource WordPress Plugins.

in addition to the above, commercial theme developers may also host their theme files on PageCDN for better cache reuse and 
performance. However, such Commercial Content is not a part of Public CDN. To know more about whether a theme avails such performance 
benefits from PageCDN, please consult the theme developer.
