Asset CleanUp Pro is a premium performance optimization plugin for WordPress that allows website owners to remove unnecessary loading of CSS and JavaScript files on each page. It is designed for those who suffer from slow sites due to the accumulation of scripts and styles that load globally even though they are not used on all pages. It is especially useful for websites with many installed plugins, marketing landing pages, online stores, and any project where loading speed directly impacts conversions and user experience.
The plugin offers granular control over each resource loaded on your site. You can unload unused CSS and JavaScript files on specific pages, posts, custom post types, category pages, tags, author archives, search pages, 404 pages, and date archives. It also allows you to apply defer and async attributes to JavaScript files without writing code, preventing the browser from blocking during the initial page load.
One of its most notable features is the ability to move CSS and JS files from the HEAD to the BODY to prevent render-blocking, or vice versa if you need early activation of certain scripts. It can also unload CSS/JS that are hardcoded directly in PHP code, widgets, or post content, even those added by plugins like Insert Headers and Footers.
The Test Mode feature is ideal for those who fear breaking their site when making changes: it allows you to apply all optimizations only for the logged-in administrator, so you can visually verify that everything works correctly before publishing the changes for all visitors. Once satisfied, you deactivate test mode and the changes are applied live.
The plugin integrates naturally with WooCommerce, allowing you to optimize product pages and store categories, as well as with the main page builders in the WordPress ecosystem. Its interface is intuitive and does not require technical programming knowledge, making it an accessible tool for both developers and site owners who want to improve their Core Web Vitals metrics and search engine rankings.
