Enable page caching, defer or delay JavaScript, lazy-load media, create and serve WebP images, minify HTML, rewrite assets to your own CDN, speed up wp-admin, and clean the database—all from one settings screen. Everything included in the plugin is free to use. There is no Pro edition, premium upgrade, subscription, usage limit, or payment required to access its features. Your hosting plan may still impose normal server, storage, PHP, or traffic limits. Optional CDN rewrite only points to a domain you configure yourself. #### Works on every WordPress site * Blogs, business sites, portfolios, and landing pages * Classic themes and block / full-site-editing themes * WooCommerce shops — cart, checkout, and account stay live (never frozen inside the page cache) * Elementor, CartFlows, and other page builders via final HTML rewrite * Plugin-heavy sites with Force Optimize so late-enqueued CSS/JS still get optimized #### 100% free—all included features unlocked * No paid plan or Pro version * No premium-only toggles * No form, page, or cache limits imposed by the plugin * No subscription or recurring payment * GPL-licensed open-source software #### Page caching * File-based HTML page cache for logged-out visitors * Early cache serving via `advanced-cache.php` when `WP_CACHE` is enabled * Configurable cache lifetime (5 minutes to 7 days) with hourly auto-cleanup of expired files * Automatic cache busting on post, comment, menu, and theme changes * URL exclusion list (path fragments) * Browser Cache-Control headers on cacheable pages * One-click purge from the settings screen * Safe drop-in install that will not overwrite another cache plugin’s `advanced- cache.php` #### CSS and JavaScript * Delay non-critical JavaScript until first user interaction * Configurable script-handle exclusions for delayed JS * Defer JavaScript when delay is off * Minify HTML (comments and excess whitespace) * Optimize Google Fonts with `display=swap` and preconnect * Option to remove Google Fonts entirely * Optional removal of block library CSS and global styles * Smart comment-reply script loading #### SEO meta * Auto title, description, keywords, and Open Graph tags when a page is missing them * Existing Yoast / Rank Math tags are left alone * Auto image alt text for empty images (decorative placeholders stay empty) #### Images and media * Automatic lazy-loading for images (`loading="lazy"`, `decoding="async"`) * First-image LCP boost (`loading="eager"`, `fetchpriority="high"`) * Lazy-loading for iframes and oEmbeds * Automatic width/height attributes to reduce CLS * Auto-resize oversized uploads to a configurable max width * Automatic WebP generation on upload (requires PHP GD `imagewebp`) * Automatic WebP serving when the file exists and the browser supports it * Configurable JPEG/WebP quality * Optional srcset disable (off by default) #### General cleanup * Disable emojis, embeds, XML-RPC, and pingbacks * Remove query strings from CSS/JS * Control Heartbeat on the front end and in admin * Remove RSD, WLW manifest, shortlink, REST discovery link, and generator meta * Disable Dashicons for logged-out visitors * Disable jQuery Migrate on the front end * Limit post revisions * Disable self-pingbacks and the capital_P_dangit filter #### Instant Page (WordPress 7.1) * Uses WordPress 7.1 speculative loading to prefetch the next page on hover * Cart, checkout, account, and sales landings stay excluded so LCP is not stolen * Falls back to a Speculation Rules script on older WordPress versions #### Preload and CDN * Optional DNS prefetch for origins you list * Optional preconnect to origins you list * Hover link prefetch for internal navigation * Optional CDN rewrite of static asset URLs to your own CDN domain #### WP Admin speed * Optimize assets across admin screens * Smart Heartbeat on list screens vs editor/Customizer * Faster post/page list queries * Disable remote browser-capability checks * Trim WooCommerce admin assets off non-Woo screens * Remove heavy dashboard widgets (News/Events, Quick Draft, Site Health, optional Activity) * Slower autosave interval * Optional Help tab hide #### WooCommerce * Load WooCommerce CSS/JS only on shop-related pages * Disable cart-fragments AJAX on non-cart pages #### Unused media * Scan uploads for images not in the Media Library and not referenced by pages, products, or Elementor * Quarantine unused files (restorable) instead of deleting them immediately * Product downloads, fonts, and WooCommerce private files are never touched #### Database tools * One-click cleanup of revisions, spam, and expired data from the settings screen * Safe, capability-checked AJAX actions with nonces #### Presets and overview * Safe Preset and Max Speed Preset * Overview with feature coverage score, cache stats, and quick purge/save actions * Speed Lab section with health checks and links to external audit tools #### Privacy and data ownership * No phone-home analytics * No submission of site content to Blog Cutter * Settings stored in your WordPress database (`bcpsf_settings`) * Cache HTML and JSON config stored in `wp-content/cache/bcpsf/` * Uninstall removes plugin options, cache files, the plugin’s own drop-in, and only this plugin’s marked `WP_CACHE` line ### External services This plugin does not load Google Fonts, analytics, or any other remote asset on its own. The settings screen uses the system font stack only. #### Optional front-end DNS prefetch / preconnect When you enable DNS Prefetch or Preconnect and list origin URLs (for example Google Fonts or a CDN), the public site may emit resource hints to those hosts. * What is sent: browser DNS / TLS handshake hints only (no content from your site) * When: only if you enable the toggles and provide origins * Why: faster connection setup to assets your theme or CDN already uses * Default: both features are off and the origin list is empty Front-end “Optimize Google Fonts” / “Remove Google Fonts” only affects fonts already enqueued by your theme or other plugins; the plugin does not force Google Fonts onto your public site by default. #### External audit links (Speed Lab) The Speed Lab screen includes links to PageSpeed Insights, GTmetrix, and Pingdom. These open in the administrator’s browser when clicked. The plugin does not call those services from the server and does not send site data unless the administrator chooses to open a link. ## Screenshots [⌊Overview dashboard with feature coverage score, cache stats, and quick actions⌉⌊ Overview dashboard with feature coverage score, cache stats, and quick actions⌉[ Overview dashboard with feature coverage score, cache stats, and quick actions [⌊Overview auto-speed coverage steps with live status⌉⌊Overview auto-speed coverage steps with live status⌉[ Overview auto-speed coverage steps with live status [⌊General cleanup toggles for emojis, embeds, Heartbeat, and head cleanup⌉⌊General cleanup toggles for emojis, embeds, Heartbeat, and head cleanup⌉[ General cleanup toggles for emojis, embeds, Heartbeat, and head cleanup [⌊CSS and JavaScript controls including Force Optimize, HTML rewrite, and delay JS⌉⌊CSS and JavaScript controls including Force Optimize, HTML rewrite, and delay JS⌉[ CSS and JavaScript controls including Force Optimize, HTML rewrite, and delay JS [⌊Automatic image and media optimization (lazy-load, LCP, WebP, resize)⌉⌊Automatic image and media optimization (lazy-load, LCP, WebP, resize)⌉[ Automatic image and media optimization (lazy-load, LCP, WebP, resize) [⌊Page cache settings with lifetime, auto-cleanup, and logged-out-only mode⌉⌊Page cache settings with lifetime, auto-cleanup, and logged-out-only mode⌉[ Page cache settings with lifetime, auto-cleanup, and logged-out-only mode [⌊WP Admin speed tools for every admin screen⌉⌊WP Admin speed tools for every admin screen⌉[ WP Admin speed tools for every admin screen [⌊Preload, Instant Page (WordPress 7.1), preconnect, and optional CDN rewrite⌉⌊Preload, Instant Page (WordPress 7.1), preconnect, and optional CDN rewrite⌉[ Preload, Instant Page (WordPress 7.1), preconnect, and optional CDN rewrite [⌊WooCommerce conditional assets and cart fragments⌉⌊WooCommerce conditional assets and cart fragments⌉[ WooCommerce conditional assets and cart fragments [⌊Database cleanup tools⌉⌊Database cleanup tools⌉[ Database cleanup tools [⌊Speed Lab health checks and external audit links⌉⌊Speed Lab health checks and external audit links⌉[ Speed Lab health checks and external audit links ## Installation 1. Upload the `blogcutter-performance-optimizer` folder to `/wp-content/plugins/`, or install through the WordPress Plugins screen. 2. Activate **BlogCutter Performance Optimizer**. 3. Go to **BlogCutter Speed** in the admin menu. 4. Apply the Safe Preset or Max Speed Preset, or toggle features individually. 5. Click **Save Settings**. 6. Optionally click **Purge Page Cache** after major content changes. 7. Test your site as a logged-out visitor (page cache is for guests by default). On activation the plugin may: * Create `wp-content/cache/bcpsf/` * Install `wp-content/advanced-cache.php` (only if another cache plugin does not already own it) * Add `define( 'WP_CACHE', true ); // Added by BlogCutter Performance Optimizer` to `wp-config.php` when that file is writable On deactivation and uninstall, those changes are reversed for this plugin’s own drop-in, settings, and only the marked `WP_CACHE` line (other plugins’ / host `WP_CACHE` lines are never altered). ## FAQ ### Is this tested on the current WordPress version? Yes. It is tested on WordPress 7.1 (Mary Lou, August 2026). WordPress 5.8 or newer is required. WordPress 7.1.1 is a bug-fix release scheduled after 7.1 and does not change this plugin’s APIs. ### Will this work on my theme, page builder, or WooCommerce shop? Yes. It is built for classic themes, block themes, Elementor, CartFlows, WooCommerce, blogs, landings, and plugin-heavy sites. Cart, checkout, and account pages stay live and are never frozen inside the page cache. ### Is every included feature really free? Yes. All functionality included in BlogCutter Performance Optimizer is available without a payment, license key, subscription, Pro plan, or premium upgrade. ### Do I need a license key or account? No. Install, activate, and configure from **BlogCutter Speed**. ### Will this conflict with other cache plugins? Possibly. Use one page-cache solution at a time. This plugin will not overwrite an `advanced-cache.php` file owned by another plugin. ### Why don’t I see cached pages when logged in? By default the front-end page cache serves logged-out visitors only. Log out or use a private/incognito window to verify HIT responses (`X-BCPSF-Cache` header). ### Does CDN Rewrite send my files to Blog Cutter? No. You enter your own CDN URL. The plugin only rewrites asset URLs on your site to that domain. ### Does WebP require special hosting? WebP generation needs PHP GD with `imagewebp`. If that function is missing, WebP creation is skipped safely. ### What happens on uninstall? uninstall.php deletes plugin options, removes this plugin’s `advanced-cache.php` drop-in when it is ours, and deletes the `wp-content/cache/bcpsf/` directory. ### Can I exclude pages from cache? Yes. Under Caching, add path fragments (one per line) such as `/cart` or `/checkout`. ### What is Instant Page? It turns on WordPress 7.1 speculative loading so the next page is prefetched when a visitor hovers a link. Cart, checkout, and sales landings are excluded. ### Is the estimated score the same as Google PageSpeed Insights? No. The in-plugin estimate reflects how many optimizations are enabled. Use PageSpeed Insights, GTmetrix, or similar tools for real lab/field scores. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “BlogCutter Performance Optimizer” is open source software.
