Use a single admin dashboard to control caching, file optimization, media performance, cache preloading, and maintenance tools. * **Page caching:** Cache public pages for anonymous visitors, with separate mobile and desktop cache files and optional advanced delivery modes. * **CSS and JavaScript optimization:** Minify and combine eligible assets, and selectively unload scripts and styles where they are not needed. * **Image loading:** Lazy-load eligible images, add dimension helpers, and prioritize important visual content with fetchpriority. * **Cache preloading:** Preload the homepage, menu links, recent content, and manually selected URLs. * **Database maintenance:** Clean up unnecessary database data and access diagnostics and system status tools. * **CDN and fonts:** Configure simple CDN hostname rewriting and manage Google Fonts loading options. * **SEO-related performance tools:** Improve resource loading and optionally use IndexNow to notify participating search engines of new or updated public URLs. QW Optimize Free works independently, with no paid add-on required for the features listed above. More advanced capabilities are available through the optional, separately installed QW Optimize Pro plugin. ### Features #### Page cache * Full-page cache for anonymous visitors * Separate mobile / desktop cache files * Early advanced-cache.php drop-in * Apache rewrite rules + Nginx-oriented guidance * Cache lifespan and built-in tracking-parameter exclusions * Manual and automatic purge #### File optimization * CSS and JS minify * CSS and JS combine * Selective asset unload * Google Fonts helpers and font-display #### Media * Image lazy load * fetchpriority for LCP images * Basic image dimension helpers #### Preload * Homepage, menus, recent posts, manual URL list * Run preload and clear queue from the admin #### Database & tools * Database cleanup * Import / export settings * System status and diagnostics * WP-CLI: purge, status, health, basic preload, settings #### CDN * Simple CDN hostname rewrite See the Free vs Pro section for what the separate Pro plugin adds. ### External services QW Optimize checks known third-party asset hostnames (for example js.stripe.com, connect.facebook.net and widget.intercom.io) to identify and protect scripts from unsafe optimization. These hostname comparisons do not themselves make network requests, send any data to those companies, or enable their services. If your site separately uses one of those services through another plugin, that plugin controls the associated requests and disclosures. This plugin may contact the following third-party services when the related features are enabled by the site admin: * Google PageSpeed Insights API — when you run a speed test from the dashboard. Sends the public URL of the page being tested and the configured Google API key, if supplied. Service: https://developers.google.com/speed/docs/insights/v5/about Privacy: https://policies.google.com/privacy Terms: https://policies.google.com/ terms * Core Web Vitals field data — retrieved through the Google PageSpeed Insights API when a report is requested. Sends the tested public URL and the configured Google API key, if supplied. Service: https://developers.google.com/speed/docs/ insights/v5/about Privacy: https://policies.google.com/privacy Terms: https:// policies.google.com/terms * IndexNow — when IndexNow is enabled, submits public URLs of new or updated content to participating search engines. Service: https://www.indexnow.org/ Terms: https:// www.indexnow.org/terms Privacy statement (in the terms): https://www.indexnow. org/terms * Google Fonts — when local Google Fonts optimization downloads font CSS/font files. Service: https://fonts.google.com/ Privacy: https://policies.google.com/privacy Terms: https://policies.google.com/terms * Google Analytics / Google Tag Manager — when the site admin enables the local analytics or tag-manager integration, QW Optimize loads the relevant Google measurement script from googletagmanager.com when enabled; it does not mirror executable JavaScript into the local cache and outputs the configured measurement/tag ID on the public site. Data collection by Google depends on the site owner’s Google configuration and consent settings. Privacy: https://policies.google.com/privacy Terms: https://marketingplatform.google.com/about/analytics/terms/us/ Broken-image checks may request image URLs referenced by your content, including external image hosts, when you start a scan. Those hosts receive the image URL and the server request, including its IP address. Preloading and server diagnostics request pages on your own site. Configured CDN rewriting and preconnect hints cause visitor browsers to contact the hosts selected by the administrator; their policies apply. No personal visitor data is sent by QW Optimize to these services by default. API keys and service identifiers entered by the site admin are stored in the WordPress database and used only for the related enabled feature. When the optional QW Optimize consent log is enabled, consent records are stored locally and may include a timestamp, accept/reject choice, and a salted pseudonymous identifier derived from the visitor IP address; the raw IP address is not stored by that feature. ### Free vs Pro The free plugin on WordPress.org includes page cache, minify/combine, lazy load, basic preload (homepage and manual URLs), database cleanup, and related performance tools. Pro is a separate paid add-on available from QWPlugins.com. It adds Critical CSS, Remove Unused CSS, Delay JS, WebP/AVIF, video facades, CDN/Cloudflare API purge, object-cache drop-in, RUM, white-label, multisite tools, sitemap and scheduled preload, and related features. Installing Pro is optional. ## Installation 1. Upload the `qw-optimize` folder to `/wp-content/plugins/` 2. Activate through the Plugins screen 3. Open QW Optimize in the admin menu ## FAQ ### Does this plugin replace a full SEO or security plugin? No. This free release focuses on cache and performance. SEO and login-security modules were intentionally left out. ### Where is Critical CSS / Delay JS / WebP? Those are part of the optional Pro plugin sold on the author site. They are not included in this free WordPress.org package. ### Will enabling cache break my site? Use the Safe preset on first install. Always test checkout and forms after enabling minify/combine. You can purge cache and disable features from the admin if needed. ### Does it work with page builders and WooCommerce? Compatibility helpers are included. Prefer defer over aggressive optimization on cart and checkout pages. ### Where is the page cache stored? Under wp-content/cache/qw-speed-cache/ (configurable). The advanced-cache.php drop- in may be installed when page cache is enabled. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “QW Optimize – Cache, Speed & SEO” is open source software.
