Optimazz – Website Optimization and Speedup

Optimazz is an all-in-one performance suite that applies the optimizations with the biggest impact on Core Web Vitals — automatically and safely. Every module is opt-in and reversible, and Optimazz never overwrites another caching plugin’s files.

Modules included:

• Page Cache — 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.
• JavaScript — defer scripts and delay them until the first user interaction to cut Total Blocking Time, with an exclusion list.
• CSS — minify, combine, and load CSS asynchronously to remove render-blocking stylesheets.
• Image Optimization — 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.
• Fonts — add font-display: swap, preconnect to font hosts, and preload font files.
• Database — clean revisions, auto-drafts, trashed posts, spam/trashed comments and expired transients, optimize tables, and schedule automatic cleanups.
• Heartbeat — reduce or disable the WordPress Heartbeat API per context to lower server load.
• Tweaks — disable emojis, embeds, dashicons, query strings, XML-RPC and pingbacks, and add DNS-prefetch / preconnect hints.
• CDN — rewrite static asset URLs to your CDN hostname.

A live performance score on the dashboard shows which optimizations are active and your biggest remaining win.

Build process and source code

The admin interface is a React application. The human-readable source lives in the src/ directory shipped inside the plugin (src/index.js and src/index.scss), and the compiled, minified output lives in build/.

To regenerate the compiled files from source:

1. Install dependencies: npm install
2. Build: npm run build

This uses the official @wordpress/scripts (webpack) toolchain — no custom or hidden build configuration. All source and build tooling are included in the plugin; nothing is obfuscated.

External services

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:

1. Google Fonts optimization (Fonts module). If — and only if — your theme or another plugin already loads Google Fonts, and you enable the Fonts module, Optimazz adds preconnect resource hints to fonts.googleapis.com and fonts.gstatic.com and can add display=swap 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 — a preconnect 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

2. CDN rewriting (CDN module). 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.

Both features are off by default and take effect only after you explicitly enable them.
