BlogCutter Performance Optimizer

BlogCutter Performance Optimizer helps improve front-end and admin performance on every kind of WordPress site—blogs, business sites, WooCommerce stores, Elementor/CartFlows landings, classic themes, and block themes—without a paid plan. 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

• 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.
