When developing or maintaining a WordPress (or any) website, it’s important to rein in the amount of JavaScript and CSS files that are included in your site and delivered to the end user. Too many files, poorly optimized files or improper load order will slow down your site and negatively affect your Search Engine Optimization efforts.

Optimize Scripts & Styles is a free WordPress plugin developed by Seismic Pixels that optimizes your site’s JavaScript and CSS files by combining, minifying and caching them in your site’s content folder. In conjunction with a site caching plugin, this will ensure your pages load fast and your customers are more likely to stay engaged.

FEATURES

  • Combine & minify all JavaScript & CSS that is enqueued
  • Stores the optimized files in the cache folder for faster page loads
  • Compatible with caching plugins like WP Super Cache and W3 Total Cache
  • Enable for logged in users (not recommended)
  • Available options to remove or ignore enqueued scripts and styles
  • Optional button in the admin bar to clear scripts and styles
  • Includes an option to remove script type attributes for HTML5 validation

CHANGELOG

1.8.9

  • Fixed an unset variable error for remove_script_type and remove_style_type

  • Added location (header or footer) to the cached files description

  • [New Feature] Added an option to remove type=’text/javscript’ from script tags so that HTML5 sites can be W3C compliant (other optimizations may be needed)
  • [New Feature] Added an option to remove type=’text/css’ from style tags so that HTML5 sites can be W3C compliant (other optimizations may be needed)
