Autoptimize is a multipurpose plugin. In most cases, we hate multipurpose plugins like Jetpack or Yoast SEO. They’re bloated, slow, and heavy. We especially dislike including features that concatenate JavaScript, CSS, or HTML files. These minification plugins often break sites.


Our preference is discrete plugins with one function and no settings. Why? You can selectively deactivate (bonus) – and they usually load in under 1 millisecond.

Note: Don’t use the recommended WebP images suggested by Autoptimize. They don’t help much and won’t work cross-browser. We aren’t fans of WebP format developed by Google zealots in 2010. Not cool. Really.

Autoptimize loads in 18 to 25 milliseconds. That’s the equal of installing 18 discrete plugins. But if you *need* Autoptimize, there’s an upside. Keep reading.

 It’s an odd plugin – but not obscure. Autoptimize is popular with over 1 million installs. Most often, it’s installed for minification benefits reducing requests. But many cool features go unused. Most people use the default settings and figure that’s good enough. And usually, it is. But there are bonuses if you want them for speed.

There’s an opportunity to remove 7-speed plugins when using Autoptimize plugin

  • a3 Lazy Load
  • Cache Enabler (or other caching plugins)
  • Disable Emojis
  • ShortPixel Optimizer
  • WP Remove Query Strings from Static Resource
  • Remove Google Fonts References
  • Any minification plugin like Better WordPress Minify plugin or others.

The Autoptimize plugin recommends using Cache Enabler plugin in tandem with it. Please test your speed without it first. We like Cache Enabler but it isn’t always necessary on a well-optimized site.

Dump ShortPixel plugin, too.

Autoptimize recommends ShortPixel Optimizer plugin. If you’re using ShortPixel, remove it. And then install free Imsanity plugin for image optimization. ShortPixel costs money. Oh? Didn’t they tell you that? Read the plugin fine print.
