automatically and safely. Every module is opt-in and reversible, and Optimazz never overwrites another caching plugin's files.<\/p>\n\n<p><strong>Modules included:<\/strong><\/p>\n\n<ul>\n<li><strong>Page Cache<\/strong> \u2014 serve static HTML instead of running PHP on every request, with smart exclusions (logged-in users, carts, query strings), automatic purging on content changes, and a cron-based cache preloader so visitors never hit a cold page.<\/li>\n<li><strong>JavaScript<\/strong> \u2014 defer scripts and delay them until the first user interaction to cut Total Blocking Time, with an exclusion list.<\/li>\n<li><strong>CSS<\/strong> \u2014 minify, combine, and load CSS asynchronously to remove render-blocking stylesheets.<\/li>\n<li><strong>Image Optimization<\/strong> \u2014 lazy-load images and iframes, add missing dimensions to prevent layout shift, generate and serve WebP\/AVIF, bulk-compress your existing library, convert opaque PNGs to JPEG, and replace YouTube embeds with a click-to-load preview.<\/li>\n<li><strong>Fonts<\/strong> \u2014 add <code>font-display: swap<\/code>, preconnect to font hosts, and preload font files.<\/li>\n<li><strong>Database<\/strong> \u2014 clean revisions, auto-drafts, trashed posts, spam\/trashed comments and expired transients, optimize tables, and schedule automatic cleanups.<\/li>\n<li><strong>Heartbeat<\/strong> \u2014 reduce or disable the WordPress Heartbeat API per context to lower server load.<\/li>\n<li><strong>Tweaks<\/strong> \u2014 disable emojis, embeds, dashicons, query strings, XML-RPC and pingbacks, and add DNS-prefetch \/ preconnect hints.<\/li>\n<li><strong>CDN<\/strong> \u2014 rewrite static asset URLs to your CDN hostname.<\/li>\n<\/ul>\n\n<p>A live performance score on the dashboard shows which optimizations are active and your biggest remaining win.<\/p>\n\n<h3>Build process and source code<\/h3>\n\n<p>The admin interface is a React application. The human-readable source lives in the <code>src\/<\/code> directory shipped inside the plugin (<code>src\/index.js<\/code> and <code>src\/index.scss<\/code>), and the compiled, minified output lives in <code>build\/<\/code>.<\/p>\n\n<p>To regenerate the compiled files from source:<\/p>\n\n<ol>\n<li>Install dependencies: <code>npm install<\/code><\/li>\n<li>Build: <code>npm run build<\/code><\/li>\n<\/ol>\n\n<p>This uses the official <code>@wordpress\/scripts<\/code> (webpack) toolchain \u2014 no custom or hidden build configuration. All source and build tooling are included in the plugin; nothing is obfuscated.<\/p>\n\n<h3>External services<\/h3>\n\n<p>Optimazz does not require any external service to function, and it works entirely on your own server by default. Two optional, admin-controlled features can reference third-party hosts:<\/p>\n\n<ol>\n<li><p><strong>Google Fonts optimization (Fonts module).<\/strong> If \u2014 and only if \u2014 your theme or another plugin already loads Google Fonts, and you enable the Fonts module, Optimazz adds <code>preconnect<\/code> resource hints to <code>fonts.googleapis.com<\/code> and <code>fonts.gstatic.com<\/code> and can add <code>display=swap<\/code> to the existing font URL. Optimazz does not add Google Fonts to a site that isn't already using them, and it does not send any personal or site data \u2014 a <code>preconnect<\/code> is only a browser hint to open a connection earlier. The fonts themselves are requested by the visitor's browser from Google, exactly as they were before the plugin, under Google's terms: https:\/\/policies.google.com\/terms and privacy policy: https:\/\/policies.google.com\/privacy<\/p><\/li>\n<li><p><strong>CDN rewriting (CDN module).<\/strong> If you enable the CDN module and enter a CDN hostname, Optimazz rewrites the URLs of your own static assets (CSS, JS, images) to that hostname so visitors' browsers load them from your CDN. The CDN is a service you choose and configure; Optimazz sends no data to it itself and is not affiliated with any CDN provider. Consult your chosen CDN's own terms and privacy policy.<\/p><\/li>\n<\/ol>\n\n<p>Both features are off by default and take effect only after you explicitly enable them.<\/p>\n\n<!--section=installation-->\n<ol>\n<li>Upload the <code>optimazz<\/code> folder to <code>\/wp-content\/plugins\/<\/code>, or install it from the Plugins screen.<\/li>\n<li>Activate the plugin through the <strong>Plugins<\/strong> menu in WordPress.<\/li>\n<li>Open <strong>Optimazz<\/strong> in the admin menu and enable the modules you want.<\/li>\n<\/ol>\n\n<!--section=faq-->\n<dl>\n<dt id=\"does%20optimazz%20work%20alongside%20another%20caching%20plugin%3F\"><h3>Does Optimazz work alongside another caching plugin?<\/h3><\/dt>\n<dd><p>Optimazz will not overwrite another caching plugin's <code>advanced-cache.php<\/code> drop-in.

The admin interface and all of the plugin's own assets are loaded normally through the WordPress enqueue functions.<\/p><\/dd>\n\n<\/dl>\n\n<!--section=changelog-->\n<h4>1.0.1<\/h4>\n\n<ul>\n<li>Subdirectory-install-safe URL-to-path mapping for CSS\/media optimization.<\/li>\n<li>Simplified the WP_CACHE handling in wp-config.php to a single WP_Filesystem edit.<\/li>\n<li>Included the React admin source (src\/) and documented the build steps.<\/li>\n<\/ul>\n\n<h4>1.0.0<\/h4>\n\n<ul>\n<li>Initial release: page cache + preloader, JavaScript defer\/delay, CSS minify\/combine\/async, image optimization (lazy-load, dimensions, WebP\/AVIF, bulk compression, PNG\u2192JPEG, YouTube facade), fonts, database cleanup, heartbeat control, tweaks, and CDN \u2014 with a React admin dashboard.<\/li>\n<\/ul>","raw_excerpt":"Website optimization and speedup \u2014 page caching, JavaScript delay\/defer, CSS optimization, lazy-load, WebP, font and database optimization.","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/srd.wordpress.org\/plugins\/wp-json\/wp\/v2\/plugin\/335656","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/srd.wordpress.org\/plugins\/wp-json\/wp\/v2\/plugin"}],"about":[{"href":"https:\/\/srd.wordpress.org\/plugins\/wp-json\/wp\/v2\/types\/plugin"}],"replies":[{"embeddable":true,"href":"https:\/\/srd.wordpress.org\/plugins\/wp-json\/wp\/v2\/comments?post=335656"}],"author":[{"embeddable":true,"href":"https:\/\/srd.wordpress.org\/plugins\/wp-json\/wporg\/v1\/users\/shiponkarmakar"}],"wp:attachment":[{"href":"https:\/\/srd.wordpress.org\/plugins\/wp-json\/wp\/v2\/media?parent=335656"}],"wp:term":[{"taxonomy":"plugin_section","embeddable":true,"href":"https:\/\/srd.wordpress.org\/plugins\/wp-json\/wp\/v2\/plugin_section?post=335656"},{"taxonomy":"plugin_tags","embeddable":true,"href":"https:\/\/srd.wordpress.org\/plugins\/wp-json\/wp\/v2\/plugin_tags?post=335656"},{"taxonomy":"plugin_category","embeddable":true,"href":"https:\/\/srd.wordpress.org\/plugins\/wp-json\/wp\/v2\/plugin_category?post=335656"},{"taxonomy":"plugin_contributors","embeddable":true,"href":"https:\/\/srd.wordpress.org\/plugins\/wp-json\/wp\/v2\/plugin_contributors?post=335656"},{"taxonomy":"plugin_business_model","embeddable":true,"href":"https:\/\/srd.wordpress.org\/plugins\/wp-json\/wp\/v2\/plugin_business_model?post=335656"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
