Frequently Asked Questions

Common questions about WP Optimizer – PageSpeed, Cache, Minify & Core Web Vitals

Yes. WP Optimizer is free and the performance features described in this readme are not locked behind a premium subscription.

WP Optimizer is a modular WordPress performance plugin that combines page caching, minification, image optimization, WebP conversion, browser caching, compression, database optimization, Core Web Vitals tools and performance diagnostics. It also includes optional maintenance, cron, security, mail and WordPress administration tools.

WP Optimizer can improve many technical factors measured by performance tools and Core Web Vitals, including caching, page weight, image delivery, compression, browser caching, layout stability and LCP resource priority. A specific score cannot be guaranteed because performance also depends on your hosting, theme, plugins, content and third-party scripts. Use Page Test and external performance tools to measure the result on your own website.

Yes, but caching is only one part of WP Optimizer. It includes static page cache, optional Redis/Memcached object cache, WP_Query cache and database query cache, together with minification, image optimization, database maintenance and performance diagnostics.

WP Optimizer stores eligible rendered HTML pages on disk. Depending on the server configuration, cached responses can be delivered using server-specific rules before a normal WordPress request finishes loading. Cache lifetime, URL rules, exclusions, query strings, cookies, user agents and automatic purging can be configured independently.

No. Redis or Memcached is only required if you choose to use the corresponding object-cache integration. Static page cache, browser caching, compression, minification, WebP, image optimization, Page Test and the other core modules work without Redis or Memcached.

Yes. WP Optimizer can minify HTML, CSS and JavaScript, including local CSS and JavaScript files. CSS and JavaScript combination is also optional. Enable each optimization separately and verify important pages after changing asset optimization settings.

Yes. WP Optimizer can compress WordPress Media Library images and generated thumbnails locally using Imagick or GD and convert supported files to WebP. Background processing can also be used for new uploads and larger media libraries.

No. The built-in image optimization and WebP conversion run locally on your server using supported PHP image-processing libraries.

Page Test is a diagnostic tool that compares a request with WP Optimizer bypassed against the current active and warmed configuration. It reports response time, TTFB, peak memory and response size and can provide diagnostic information about slow queries, repeated queries and expensive callbacks.
