Fonts, lazy loading, CSS/JS


Optimise used fonts with FontSquirrel or Everything Fonts. Unused characters are removed from the font sets, thus reducing the size many times over. You can find more information on this topic in the Mightybites article about fonts.

Image Lazy Loading

Only load images outside the viewport when they are needed. Therefore add the Lazysizes script to your pages or use WordPress plugins like SmushAutoptimize or Hummingbird.

JavaScript and CSS

Optimize and compress JavaScript and CSS to significantly reduce data. Use either WordPress plugins like Autoptimize, Hummingbird, WP Rocket or your own scripts.


Caching temporarily saves your website as a static page and thus reduces a lot of data and CO2. Use for example W3 Total Cache or Hummingbird as WordPress caching plugin and achieve better results in performance and data load.
