WP Scripts & Styles Optimizer


Optimization of included JavaScript- and CSS-files can be a very important thing, if you want a faster site. Many WordPress plugins comes with multiple third-party and/or own JavaScript-files that are then often be included on every page of your site. In worst cases you have more than one of the same file included on your site. That slows down your site!

But also “Render blocking” can easily slow down a website. Every external JavaScript- or CSS-file, that is included in the head of your site, blocks the site from rendering, until all files are completely processed. It’s a common practice to move all these Scripts and Styles (except critical CSS) to the footer of your site, so the rendering is no longer blocked and your website loads faster.

This is where WP Script Optimizer helps you! It makes it possible to control the output of every registered JavaScript or CSS-file. You can easily create rules for it or deactivate files completely. You can also move files to the footer of your site or vice versa.

Check out the following lists for all currently avaiable and planned features. If you like this plugin, please upvote and comment. That would be really helpful.

What you can currently do with WP Script Optimizer

  • Get an overview of all frontend JavaScript and CSS files, that are included on your site (divided in categories)
  • Control scripts and styles for as many single pages as you want or simply globally
  • Change the positioning (Header/Footer) of specific JavaScripts / CSS or all at once
  • Deactivate specific Javascripts or CSS-files completely, if not needed
  • Easily create logical rules to control under which conditions a file is included or not (by use of wordpress’s conditional tags)

What you can do in future with WP Script Optimizer (planned, but not currently implemented)

  • Minify and/or encrypt JavaScript- and CSS-files
  • Include your own JavaScript/CSS files or JavaScript/CSS inline code, without do it manually through functions.php
  • Add extra code to any registered JavaScript or CSS-file
  • Concatenate two or more (or all) files of one type (JS or CSS) to speed up loading times
  • Better overview of dependents and its dependencys
  • … feel free to make suggestions 🙂

IMPORTANT – Please read:

This plugin can not decide if a file is needed or not needed in a specific situation. Your settings have the potential to break features and functions of your site. If that is the case, you can easily change or delete your settings via the admin panel, so everything will be like it was before.

tl;dr: you have to know what you’re doing 😉

This plugin is exactly what I needed to combat “standard practice” aka “i don’t care about user experience” coding. How can I donate to you or give you $ for helping me out so much?

After the Gutenberg update, My Enfold theme and LifterLMS scripts would cancel each other out. Once I installed WP S & S, I am able to manage which scripts fire off on what pages/posts. That is gold!! If you can, please develop it further, I would definitely throw money at such a robust tool. Thanks!

no doubt, this plugin is very goog plugin, it is simple and powerful. but from now on, this plugin already has been update and add more functions according to user feedback and youself developing plan. i think this is not fit. i think your plan is very good, and there are very many good idea here. even i suggest you sales this plugin, but you should do more thing for this. so your user can give better plugin, you can get corresponding reward, it is real fair. or you should give up this plugin if you have not enough time or other reasons.

What a great plugin…exactly what I needed! I would like to also suggest that an import/export settings feature would be very useful.

This plugin is great! I’ve been using it for the last several months and it has really helped to cut down the number of HTTP requests and also helps my pages load faster. The rules are easy to set up, and the global function along with sync with global make the job a lot faster. Lastly, the support is excellent and lightning fast!

Contributors & Developers

“WP Scripts & Styles Optimizer” is open source software. The following people have contributed to this plugin.




  • CHANGE: Remove cURL and use WP-HTTP API instead to improve compatibility.


  • FIX: Last update produces a bug that could potentially prevent scripts from being enqueued. This is now fixed.


  • FIX: Localized script data will now be used dynamically to make sure data like nonces, which are being created at runtime, work properly.


  • FIX: Add useragent to CURL requests to prevent HTTP error 403.


  • FIX: Handles without a src-value will be registered and enqueued correctly now.
  • CHANGE: The lists don’t show handles without a src-value anymore. These handles don’t represent real files and are only there to force other scripts or styles to be enqueued. (e.g. for backwards compatibility).


  • Required WordPress version raises to 4.4.0.
  • Changed the upper tabs to “Global” and “Single pages”.
  • Scripts and styles can now be controlled on one page. Header and footer can be switched via tabs.
  • Added the ability to control also single pages. They can be added and controlled via the “Single Pages” tab.
    • New pages can be added by pasting the url into the input field and click on “Get Scripts & Styles”.
    • Saved pages can be found in a list on the left. After clicking a list item, the scripts & styles associated with this page will be loaded.
    • The settings for single pages can be easily synchronized with the global settings, if needed.
    • All saved pages can be updated or deleted as once or separately.
  • Improved admin notices for better information about things that happen, e.g. adding/deleting entrys or theme/plugin changes.


  • Changed the name of the plugin to “WP Scripts & Styles Optimizer”.
  • Major improvements in the way how files are handled. Instead of simply deregister any deactivated or conditional file, it now deregisters all files and enqueue them back if not deactivated completely or conditions didn’t match. This means more control over the whole process and is a step forward with view on future features.
  • CSS-files can now moved into the footer! That was only possible due to the change above.
  • The WordPress JavaScript “wp-embed” can now be changed by the plugin.
  • The “jquery” handle has now an explanation text, that it’s only a placeholder for “jquery-core” and “jquery-migrate”.
  • Added plugin version to own javascript and css files to force a reload after update (caching).


  • Improve internal handling of default options
  • Fix a problem that prints a PHP Error in some cases.


  • Complete new UI that no longer use WordPress’s WP_List_Table class. Instead of one table list, it is now divided into lists for scripts and styles, which are itself separated in header and footer.
  • Including Font-Awesome Icon-Library for styling purposes.
  • Added a new option to reset every script or style to its original state. (Per item or as bulk-action)
  • Added a help page to explain the plugin’s functions.
  • Several code improvements


  • Fixed a bug, which triggers a PHP notice for some users


  • Fixed some bugs


  • Initial Release
