Beplus Performance Booster is a no-bloat performance plugin that gives you fine-grained 
control over your site’s front-end assets. All features can be toggled independently 
from a single settings page (Settings > Beplus Performance Booster).
All front-end optimisations are bypassed for logged-in administrators so you never 
accidentally break the admin panel or your own editing experience.
Feature summary:
<ul>
<li>JavaScript delay and defer with per-script exclude list</li>
<li>CSS file and inline minification with cache</li>
<li>Non-render-blocking stylesheet loading</li>
<li>Lazy load images with IntersectionObserver fallback</li>
<li>Remove emoji, wp-embed, Gutenberg CSS, WooCommerce assets on non-shop pages</li>
<li>HTML minification and comment stripping</li>
<li>Browser cache and gzip/brotli rules via .htaccess</li>
<li>Per-page option to disable the cache for specific posts/pages</li>
</ul>
<h3>Settings Reference</h3>
Navigate to Settings > Beplus Performance Booster to configure the plugin.
<h4>⚡ JavaScript Optimization</h4>
Delay JS Execution 
Default: off
Delays all non-excluded front-end scripts until the first user interaction (click, 
scroll, keydown, or touchstart). After 5 seconds without interaction the scripts 
load automatically as a safety fallback. Best for scripts that are not needed until 
the user actually engages with the page (e.g. chat widgets, marketing pixels).
Defer Non-Critical JS 
Default: off
Adds the <code>defer</code> attribute to every non-excluded <code><script></code> tag so scripts are 
fetched in parallel and executed after the HTML is parsed. jQuery and 
jquery-migrate are always protected from deferral.
Exclude JS Files 
Default: empty
One URL keyword per line. Any script whose <code>src</code> attribute contains a listed 
keyword is excluded from both Delay and Defer. Use this to protect scripts that 
must run immediately (e.g. analytics that need to capture the first page view).
Examples: <code>jquery</code>, <code>woocommerce</code>, <code>my-critical-script</code>
<h4>🎨 CSS Optimization</h4>
Minify Inline CSS 
Default: off
Strips block comments (<code>/* … */</code>), collapses redundant whitespace, and removes 
trailing semicolons from every inline <code><style></code> block in <code><head></code>. License 
comments (<code>/*! … */</code>) are preserved. Spaces around <code>+</code> are intentionally kept 
so <code>calc(100% + 20px)</code> expressions are never broken.
Minify CSS Files 
Default: off 
Requires: wp-content/uploads/bepluspb-cache/ directory to be writable
Minifies every enqueued external CSS file and serves the cached version from 
 wp-content/uploads/bepluspb-cache/. Already-minified <code>*.min.css</code> files and 
external CDN stylesheets are skipped automatically. Cache files are named using a 
12-character content MD5 hash so they self-invalidate whenever the source changes.
Non-Render-Blocking CSS 
Default: off
Converts <code><link rel="stylesheet"></code> tags to the preload + onload swap pattern:
<pre><code><link rel="preload" as="style" onload="this.onload=null;this.rel='stylesheet'">
<noscript><link rel="stylesheet" ...></noscript>
</code></pre>
This prevents stylesheets from blocking the initial render. A <code><noscript></code> fallback 
ensures CSS loads correctly even when JavaScript is disabled.
Tip: if you see a flash of unstyled content (FOUC), add your theme’s main stylesheet 
URL keyword to the Exclude CSS Files list.
Exclude CSS Files 
Default: empty
One URL keyword per line. Stylesheets whose <code>href</code> contains a listed keyword are 
left completely untouched by both the Non-Blocking and Minify CSS Files features.
<h4>🖼️ Lazy Load Images</h4>
Enable Lazy Loading 
Default: off
Adds <code>loading="lazy"</code> to qualifying <code><img></code> tags found in post content, featured 
images, widget text, and <code><picture></code> elements. For browsers that do not support the 
native <code>loading</code> attribute, a small IntersectionObserver polyfill is injected into 
 wp_footer (activates only when native support is absent).
Skip First N Images 
Default: 1
Images 1 through N are marked <code>loading="eager"</code> instead of <code>loading="lazy"</code>. 
Set this to at least 1 to protect the hero/LCP image from being lazy-loaded, which 
would hurt Core Web Vitals. Accepts 0–20.
Exclude by CSS Class 
Default: empty
Comma-separated CSS class names. Any <code><img></code> that has one of these classes loads 
eagerly (not lazily).
Example: <code>hero-image, no-lazy, skip-lazy</code>
Exclude by Element ID 
Default: empty
Comma-separated element IDs. Any <code><img></code> with a matching <code>id</code> attribute loads 
eagerly.
Example: <code>hero-banner, site-logo</code>
Exclude by Filename 
Default: empty
Comma-separated partial filename strings. Any <code><img></code> whose <code>src</code> URL contains one 
of these strings loads eagerly.
Example: <code>logo, hero, banner</code>
<h4>🗑️ Remove Unused Assets</h4>
Remove Emoji Scripts 
Default: off
Removes the WordPress emoji detection script, its inline stylesheet, and the 
 s.w.org DNS prefetch hint. Safe to enable if you use real Unicode emoji in your 
content — browsers display them natively without the WordPress helper.
Remove oEmbed / wp-embed 
Default: off
Removes the <code>wp-embed.js</code> script and the oEmbed discovery links added to <code><head></code>. 
Also unregisters the oEmbed REST API endpoint. Disable only if you rely on 
embedding your WordPress posts inside other websites.
Remove Block / Gutenberg CSS 
Default: off
Dequeues <code>wp-block-library</code>, <code>wp-block-library-theme</code>, and <code>global-styles</code> 
stylesheets on the front-end. Disable if your theme or content depends on 
Gutenberg block styles.
Disable WooCommerce Assets on Non-Shop Pages 
Default: off 
Requires: WooCommerce active
Dequeues WooCommerce scripts and styles on pages that are unrelated to the shop, 
cart, checkout, or account. WooCommerce assets are always kept on those pages.
<h4>📄 HTML Optimization</h4>
Minify HTML Output 
Default: off
Collapses redundant whitespace between HTML tags in the full page output. Content 
inside <code><pre></code>, <code><textarea></code>, <code><script></code>, and <code><style></code> tags is always preserved 
exactly as-is.
Remove HTML Comments 
Default: off
Strips HTML comments (e.g. theme generator tags, plugin banners) from the page 
output. Conditional IE comments are also removed.
Remove Inline JS Comments 
Default: off
Removes <code>//</code> single-line and <code>/* … */</code> block comments from inline <code><script></code> 
blocks in the HTML output. String literals and template literals are never 
modified. License comments (<code>/*! … */</code>) are preserved.
Remove Inline CSS Comments 
Default: off
Removes <code>/* … */</code> block comments from inline <code><style></code> blocks in the HTML output.
<h4>🚀 Browser Cache Headers (.htaccess)</h4>
Enable Browser Caching 
Default: off 
Requires: Apache with mod_expires, mod_headers, mod_deflate. .htaccess writable.
Injects the following directives into the root <code>.htaccess</code> file inside a clearly 
labelled block that is never duplicated:
<ul>
<li>Gzip compression (mod_deflate) for HTML, CSS, JS, JSON, SVG, and fonts.</li>
<li>Brotli compression (mod_brotli, Apache 2.4.26+) for the same types.</li>
<li>Expires headers (mod_expires): 1-year cache for static assets; no-cache 
for HTML and API responses.</li>
<li>Cache-Control headers (mod_headers): <code>max-age=31536000, public, immutable</code> 
for CSS, JS, images, and fonts.</li>
</ul>
Disabling this option or deactivating the plugin removes the injected block cleanly.
<h4>📦 JS File Minification & Cache</h4>
Minify JS Files 
Default: off 
Requires: wp-content/uploads/bepluspb-cache/ directory to be writable
Minifies every enqueued JavaScript file using a safe character-by-character comment 
stripper that correctly handles string literals, template literals, and URL protocol 
slashes (<code>https://</code>). Already-minified <code>*.min.js</code> files and external CDN scripts are 
skipped. Cache files use a 12-character content MD5 hash for automatic cache busting.
Lines are never joined to avoid breaking JavaScript’s Automatic Semicolon Insertion 
(ASI) rules.
Cache Status
Shows how many CSS and JS files are currently stored in the cache directory 
(<code>wp-content/uploads/bepluspb-cache/</code>). Use the “Clear CSS/JS Cache” button to delete 
all cached files; they are regenerated on the next page load.
The “Beplus Performance Booster” item in the WordPress admin bar (visible to administrators on 
both the front-end and back-end) shows cache size and file count in a dropdown panel 
and provides a one-click button to clear the cache.
<h4>Per-Page Cache Disable (Meta Box)</h4>
Every post and page edit screen includes a “Beplus Performance Booster” meta box in the sidebar. 
Checking Disable CSS/JS cache optimizations for this page/post stores the 
 _bepluspb_disable_cache flag in post meta. When set, the Minify CSS Files and Minify 
JS Files features are bypassed for that specific URL and the original (unminified) 
files are served instead. Useful for debugging or resolving conflicts on a specific 
page without disabling minification site-wide.

Beplus Performance Booster

Lightweight WordPress optimizer with JS/CSS minification, lazy loading, asset cleanup, and browser cache headers. Zero dependencies.

Development for this plugin is now done on <a href="https://github.com/Launch-Interactive/Merge-Minify-Refresh" rel="nofollow ugc">GitHub</a>. Pull requests are welcome.
This plugin merges/concatenates Cascading Style Sheets & Javascript files into groups. It then minifies the generated files using Minify (for CSS) and Google Closure (for JS – fallback to Minify when not available). Minification is done via WP-Cron so that it doesn’t slow down the website. When JS or CSS changes files are re-processed. No need to empty cache!
Inspired by <a href="https://wordpress.org/plugins/minqueue/" rel="ugc">MinQueue</a> and <a href="https://wordpress.org/plugins/dependency-minification" rel="ugc">Dependency Minification</a> plugins.
Minification by <a href="https://github.com/matthiasmullie/minify" rel="nofollow ugc">Minify</a> and <a href="https://developers.google.com/closure/" rel="nofollow ugc">Google Closure</a>
In order to ensure fast loading times it’s recommended to set long expiry dates for CSS and JS as well as make sure gzip or deflate is on.
Version 1.10 added should_mmr filter which allows developers to disable MMR when needed. You could use this to disable MMR for certain WordPress roles or with some Page Builders. Three new plugins have been created that utilise this: 
<a href="https://wordpress.org/plugins/mmr-disable-for-divi" rel="ugc">Merge + Minify + Refresh Check DIVI</a>, <a href="https://wordpress.org/plugins/mmr-disable-for-visual-composer-editor" rel="ugc">Merge + Minify + Refresh Check Visual Composer</a> and <a href="https://wordpress.org/plugins/mmr-disable-for-beaver-builder-editor" rel="ugc">Merge + Minify + Refresh Check Beaver Builder</a>. Please install these when required.
Version 1.6 added support for HTTP2 Server Push to further speed up your requests (thanks to <a href="https://www.slightfuture.com" rel="nofollow ugc">Daniel Aleksandersen</a>).
Version 1.6.9 added the ability to specify the cache directory. Set MMR_CACHE_DIR & MMR_CACHE_URL constants in wp-config.php. MMR_CACHE_DIR must be full server path and MMR_CACHE_URL must be absolute URL for this to work correctly (thanks to <a href="https://www.slightfuture.com" rel="nofollow ugc">Daniel Aleksandersen</a>).
Version 1.6.11 added the ability to specify seperate cache urls for javascript and CSS. Use MMR_JS_CACHE_URL & MMR_CSS_CACHE_URL to replace MMR_CACHE_URL.
Version 1.7.0 added the ability to generate .css.gz & .js.gz files. Your webserver may need to be configured to use these files. Here is how to use these files in Apache (mod_rewrite, mod_deflate and mod_headers need to be enabled):
<pre><code><IfModule mod_rewrite.c>
 <IfModule mod_deflate.c>
 <IfModule mod_headers.c>
&#35;Serve gzip compressed CSS files if they exist and the client accepts gzip.
RewriteCond %{HTTP:Accept-encoding} gzip
RewriteCond %{REQUEST_FILENAME}\.gz -s
RewriteRule ^(.*)\.css $1\.css\.gz [QSA]

&#35;Serve gzip compressed JS files if they exist and the client accepts gzip.
RewriteCond %{HTTP:Accept-encoding} gzip
RewriteCond %{REQUEST_FILENAME}\.gz -s
RewriteRule ^(.*)\.js $1\.js\.gz [QSA]

&#35;Serve correct content types, and prevent mod_deflate double gzip.
RewriteRule \.css\.gz$ - [T=text/css,E=no-gzip:1,E=is_gzip:1]
RewriteRule \.js\.gz$ - [T=text/javascript,E=no-gzip:1,E=is_gzip:1]
Header set Content-Encoding "gzip" env=is_gzip
 </IfModule>
 </IfModule>
</IfModule>
</code></pre>
Version 1.8.8 added a “merge_minify_refresh_done” hook that fires when JS or CSS has changed.
Version 1.11 added two new constants: 
MMR_USE_CLOSURE – allows Google Closure Javascript minification to be disabled. 
MMR_REMOVE_EXPIRED – disables removing expired files.
Version 1.13 added two new filters which can be used to exclude specific files: 
mmr_ignored_css_sources 
mmr_ingnored_js_sources 
Version 1.13 also automatically moves the WordPress inline styles to a global stylesheet which it then enqueues.
Version 1.14.3 added two new filters which can be used to modify the output before it gets saved: 
modify_css_output_before_save 
modify_js_output_before_save
Note Installing this plugin on a server with the eAccellerator module installed has the potential to break as Minify uses anonymous functions which return NULL. <a href="https://github.com/eaccelerator/eaccelerator/issues/12" rel="nofollow ugc">View eAccellerator Issue Thread</a>

Merge + Minify + Refresh

I just tested this on localhost not on a production site but its seems like it works like a charm and does its jobs really well.

So far i can't see any script or style conflicts, so i guess on a good codebase (probably when all scripts and styles are integrated via WordPress enqueue API) this plugin just works.

Im gonna test the impact on a live website but i think this is gonna be quite relevant.

Seems really powerfull

Great plugin. Works as expected.
Thank you.

Great plugin.

Merges/Concatenates CSS & Javascript and then minifies using Minify (for CSS) and Google Closure (for JS with Minify as a fallback).
