What the author says it does
WordPress themes and plugins often load CSS and JavaScript on pages that do not use them. A contact form may load on the homepage, a slider may load on a plain article, or store-related files may load outside the shop.
Asset CleanUp shows you what each page loads and lets you unload what is not needed. This can reduce HTTP requests, page weight, and browser work while complementing your existing caching setup.
Use Test Mode to validate changes as an administrator before they affect visitors.
Asset CleanUp gives you precise, testable control over every optimization.
A safer workflow, without giving up control
The Dashboard keeps the technical detail experienced users need while guiding first-time users through Getting Started, Test Mode, and the central Overview page. Test changes before they affect visitors, then review and manage existing or leftover rules from one place.
CSS and JavaScript management
- View loaded stylesheets and scripts, organized by their source.
- Unload unnecessary CSS and JavaScript on the homepage and on individual posts, pages, and custom post types.
- Manage assets from the Dashboard, the post/page edit screen, or the front-end view.
- Review unload rules, exceptions, asset attributes, page options, and leftover entries from the Overview page.
- Minify and combine supported CSS and JavaScript, including supported inline code.

Questions the author answers
Is Asset CleanUp a caching plugin?
No. Asset CleanUp controls which CSS, JavaScript, and other optimizations WordPress outputs. It works best alongside a page cache, server cache, or CDN.
Does Asset CleanUp automatically remove unused CSS or generate Critical CSS?
No. You decide which assets to unload and provide any Critical CSS yourself. This keeps each optimization inspectable and under your control, but it also means that every change should be tested.
Can Asset CleanUp improve Core Web Vitals or PageSpeed scores?
It can help when unnecessary CSS or JavaScript contributes to transfer size, render blocking, or browser work. Results still depend on your theme, plugins, hosting, caching, media, third-party scripts, and configuration. No plugin can guarantee a particular score.
Can unloading a CSS or JavaScript file break the page?
Yes, if that file is required for the page’s layout or functionality. Use Test Mode, make one meaningful change at a time, and test desktop, mobile, forms, navigation, popups, and other interactive elements before publishing the rule to visitors.
I am not sure which assets to unload. Where should I start?
Start with obvious candidates:
- Contact-form assets on pages without a form.
- Slider or gallery assets on pages without a slider or gallery.
- Store-related assets on pages outside the shop flow.
Avoid unloading WordPress core files or dependency files unless you understand what relies on them.
Why are my changes not taking effect?
The most common cause is caching. Clear plugin, server, browser, and CDN caches, then test as a logged-out visitor. Also check whether Test Mode is still enabled and whether another optimization plugin is applying the same type of rule.
See the detailed troubleshooting guide.
Latest changelog entry
- New: Admin Bar transfer savings estimates for unloaded CSS/JS files and removed inline code, with AJAX-based measurements and Brotli/GZIP indicators.
- Improvement: Separate effective asset unloads from rules that had no effect on the current page, with inactive rules grouped by asset type.
- Improvement — Rule Management: “Overview” is now the recommended place to review and manage bulk rules, including dormant rules left behind by deleted pages or deactivated plugins. Removed “Bulk Changes” from the top navigation, WordPress sidebar, and Admin Bar.
Screenshots
CSS & JS Manager — inspect the assets loaded on a page and unload unneeded CSS or JavaScript by page or site-wide. 
Overview — review active unload rules, load exceptions, async/defer attributes, and stale entries in one place. 
Manual Critical CSS — add and manage your own Critical CSS for individual pages and other WordPress contexts. 
Getting Started — follow a guided, safety-first workflow from Test Mode to your first optimization.

Where this page's numbers come from
Read from the WordPress.org plugin API on , when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin.
