Frequently Asked Questions

Common questions about Asset CleanUp: Page Speed Booster

No. Asset CleanUp controls which CSS, JavaScript, and other optimizations WordPress outputs. It works best alongside a page cache, server cache, or CDN.

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.

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.

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.

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.

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.

WordPress-enqueued assets are the easiest to detect and manage. Some files may be hardcoded, injected dynamically after the page loads, removed earlier by another plugin, or hidden by a cached response. Try another asset-retrieval method or the front-end manager. Advanced hardcoded asset management is available in Asset CleanUp Pro.

Yes. Asset CleanUp is commonly used with caching plugins and CDN services. Do not enable the same minify, combine, or related optimization in more than one tool, because overlapping transformations can cause conflicts or make troubleshooting difficult.

Yes. Each site can be configured independently.
