About Revo Optimizer plugin

The plugin provides the passage of Google Lighthouse tests on points:
- Preload key requests
- Ensure text remains visible during webfont load
- Image elements do not have explicit width and height

Improves performance on test point:
- Elimination of resources that block rendering

How it works

  • Clear theme fonts cache and adding `link preload` tags
  • For font styles, adds font-display: swap;  style

  • Adds the width and height attributes to the images (if they were specified in the element settings)

  • Adds the `decode="async"` attribute for images
  • Patch theme files to remove Bootstrap and IcoMoon styles
  • Inline connect or defer loading `theme.js` file

  • Move to the Footer and `defer` loading theme icons file

  • Move to the Footer theme analytics file

  • Move to the Footer theme newsletter file

  • DNS-prefetch/preconnect for Google Analytics script
  • Auto preload for all logo images

  • Auto preload for boxed theme background image

  • Disable loading JCE columns CSS styles
  • Inline include for language switcher styles
  • Inline include for theme.update styles [new]

If you do not use Bootstrap components on the site, you can patch the theme to disable Bootstrap styles, thereby reducing the size of the `template.css` style by almost 2 times.

You need to re-patch after each update of the theme version.


  • Joomla 3.9.x

How to use it:

  • Activate the plugin after installation
  • Open settings and apply a style patch (if necessary).

Important notes
  • Don't use DEFER mode for theme.js file if you use Transparent Header on your layouts!
  • The plugin uses modified theme classes, which can be changed in new versions. After each theme update, make a new patch of styles and recompile the theme styles. In case of problems, simply disable the plugin and reinstall the Yootheme Pro package.
