Optimize Scripts & Styles optimizes your site’s JavaScript and CSS files by combining, minifying and caching them. This will help your site’s overall performance and user experience by reducing the number of files served up and the overall size of these files.
For developers, this allows you to maintain uncompressed versions for development themes or plugins, while compressing them for a production environment.
For you SEO buffs, it cleans up the number of scripts that get included and downloaded to your site visitors, helping your overall PageSpeed score.
Header and footer script locations are maintained as well as any localized data used for the scripts and the minified files are stored in the /cache folder, making it friendly for plugins like WP Super Cache. Media attributes are also maintained for print stylesheets.
<h3>Features</h3>
<ul>
<li>Combine & minify all JavaScript & CSS that is enqueued</li>
<li>Stores the optimized files in the cache folder for faster page loads</li>
<li>Compatible with caching plugins like WP Super Cache and W3 Total Cache</li>
<li>Enable for logged in users (not recommended)</li>
<li>Available options to remove or ignore enqueued scripts and styles</li>
<li>Optional button in the admin bar to clear scripts and styles</li>
<li>Includes an option to remove script type attributes for HTML5 validation</li>
</ul>

AssetPilot helps you speed up WordPress by controlling which scripts and styles load on which pages — without guessing handle names in <code>functions.php</code>.
Scan a real page URL, see every enqueued asset (and many from the HTML), then create rules to disable, defer, async, preload, or set fetch priority — only where your conditions match (homepage, shop, mobile, logged-in users, specific URLs, and more).
Built for site owners who want measurable wins and for developers who want conditional dequeue with guardrails: validation warnings, dependency insight, scan history, and Safe Mode if something breaks.
<h4>Why AssetPilot instead of a simple “unload” plugin?</h4>
<ul>
<li>See before you change — scan a URL and browse assets with origin, size, and usage hints.</li>
<li>Rules, not one-off hacks — reusable conditions (page type, archive, WooCommerce views, device, auth, URL).</li>
<li>Bulk actions — one rule for many handles (e.g. a plugin’s scripts everywhere except checkout).</li>
<li>Safer changes — conflict checks, impact preview, optional verification, automatic runtime pause after repeated errors.</li>
<li>Stay in control — dependency graph, recommendations, debug logs, and Safe Mode.</li>
</ul>
<h4>What you can do</h4>
<ul>
<li>Disable scripts and styles you do not need on specific views</li>
<li>Defer or async JavaScript to reduce render-blocking work</li>
<li>Preload critical scripts, styles, fonts, and images</li>
<li>Set <code>fetchpriority</code> on images and preloads</li>
<li>Target by singular page, post type, archive, URL fragment, query string, device, login state, user role, WooCommerce page type, and scan URL</li>
<li>Create bulk rules from the asset list</li>
<li>Review optimization recommendations from scan data</li>
<li>Explore asset dependencies in a visual graph</li>
<li>Keep scan history and compare what changed over time</li>
</ul>
<h4>Typical use cases</h4>
<ul>
<li>Stop a plugin’s CSS/JS on pages where it is not used (blog posts, landing pages, archives)</li>
<li>Defer non-critical scripts on catalog pages while keeping checkout intact</li>
<li>Preload hero fonts or LCP images on key templates only</li>
<li>Audit what Elementor, WooCommerce, or form plugins actually enqueue before tightening rules</li>
</ul>
<h4>How it works</h4>
<ol>
<li>Open AssetPilot → Assets and scan a page (your homepage, a product page, a form page, etc.).</li>
<li>Pick an asset (or select several for a bulk rule).</li>
<li>Choose an action and conditions (where the rule applies).</li>
<li>Review validation and impact, then save.</li>
<li>Visit the front end — use Safe Mode anytime you need to disable all runtime rules instantly.</li>
</ol>
The block editor includes an AssetPilot sidebar on supported setups so you can jump from a post to asset management with context.
<h4>Requirements</h4>
<ul>
<li>WordPress 6.2+</li>
<li>PHP 8.1+</li>
<li>Administrator access to configure rules</li>
</ul>
Frontend runtime changes apply to public site views, not the WordPress admin dashboard.
<h3>Getting started</h3>
First rule in a few minutes
<ol>
<li>Assets → enter your site homepage URL → scan.</li>
<li>Find a script or style from a plugin you suspect is unnecessary on the homepage.</li>
<li>Click to create a rule → choose Disable (or Defer for scripts).</li>
<li>Set a condition such as “this scan URL only” or “non-WooCommerce pages” if you are testing carefully.</li>
<li>Save, open the homepage in a private window, and confirm the site still works.</li>
</ol>
Use Recommendations after a few scans for ideas (duplicate libraries, large files, low usage patterns).
Create Rule is opened from assets or recommendations — it is the guided wizard for actions, conditions, validation, and review.
<h3>Safe Mode</h3>
If the site looks wrong after applying rules, enable Safe Mode while logged in as an administrator:
<pre><code>/wp-admin/?assetpilot-safe-mode=1
</code></pre>
Safe Mode turns off all frontend runtime rule changes for the whole site. The admin UI, REST API, scanning, and rule editing still work. Clear any page cache after enabling if changes seem to stick.
If repeated frontend fatals occur, AssetPilot pauses runtime rules for 30 minutes automatically. Resume early from Settings or:
<pre><code>/wp-admin/admin.php?page=assetpilot-settings&assetpilot-resume-runtime=1<h3>Development</h3>
</code></pre>
