Let's Clear Things Up

BoostPro is designed to minimize that risk. The default settings are conservative and work well on the vast majority of WordPress sites. Core features like page caching, lazy loading, emoji cleanup, and heartbeat control are low risk and rarely cause issues. The advanced options (JS defer, unused CSS removal, CSS/JS minification) can push performance further, but we recommend testing them on a staging site first since every theme and plugin combination is different.

BoostPro includes file-based page caching that saves fully rendered HTML pages to disk and serves them directly on subsequent visits, bypassing PHP and WordPress entirely. It automatically excludes logged-in users, POST requests, WooCommerce carts, and pages that set the DONOTCACHEPAGE constant. You can configure the cache expiry, add custom URL exclusions, and the cache is automatically purged when you update content. If your host already provides server-level caching, BoostPro detects the conflict and disables its own cache to avoid issues.

BoostPro includes file-based page caching with configurable expiry and third-party cache purging (19+ systems), smart lazy loading for images, iframes, and CSS background images with exclusion patterns, remove unused CSS per URL with delivery options, CSS and JavaScript minification, WebP and AVIF image conversion with bulk optimization and image resizing, per-image optimize/delete from the Media Library, video placeholders for YouTube and Vimeo, add missing image dimensions, local Google Fonts hosting with font preloading, emoji and embed cleanup, heartbeat control (frontend/admin/editor independently), remove query strings, per-script JavaScript defer and delay with 28+ quick exclusion presets, speculative loading, auto-preconnect, advanced preload rules, auto-preload LCP image, CDN URL rewriting for static assets, a frontend Resource Manager for disabling scripts and styles per page, per-page/post disable controls, admin bar integration, global killswitch, scheduled database cleanup, and WP-CLI commands. All features are included in every tier.

Yes. BoostPro automatically detects when you're editing in Elementor, Divi, Beaver Builder, Brizy, Bricks, and other page builders and disables its optimizations during editing so they don't interfere with the builder interface. On the frontend, all optimizations apply normally. If you run into a visual issue on a specific page, use the per-page disable controls to turn off individual features for that URL.

BoostPro's Remove Unused CSS (RUCSS) analyzes each URL on your site and strips out CSS rules that the page doesn't use. The optimized CSS can be inlined directly into the page or served as a separate file. You control how original stylesheets are handled: load them asynchronously, delay them until user interaction, or remove them entirely. Specific stylesheets and selectors can be excluded to protect dynamic styles. Results are cached per URL so subsequent visits are served instantly.

BoostPro converts your JPEG and PNG images to WebP and AVIF formats using your server's GD or ImageMagick library. No external API or cloud service required. You can bulk optimize your entire media library, enable auto-optimize on upload, or optimize individual images from the Media Library. Original files are always preserved. Converted files are stored separately and served automatically via .htaccess rewrite rules (Apache/LiteSpeed) or picture tags (Nginx), with AVIF preferred when the browser supports it. A single quality preset maps to optimized values for each format.

BoostPro scans for 27 plugins that overlap with its features, including caching plugins, image optimizers, lazy loading plugins, and minification tools. When it finds one, it shows an admin notice with a one-click deactivation link for each conflicting plugin. For caching plugins specifically, BoostPro hard-blocks its own page cache toggle until the conflict is resolved, so you never end up with two caching layers fighting each other.

Yes. BoostPro automatically detects server-level caching from hosts like WP Engine, Kinsta, Cloudways, and SiteGround. When it finds one, it disables its own page cache to avoid conflicts and focuses on the optimizations your host doesn't provide: lazy loading, resource cleanup, font optimization, CSS optimization, and database maintenance. No duplicate functionality, no stale content issues.

AVIF is a next-generation image format that typically produces files 20-50% smaller than WebP at equivalent visual quality. BoostPro can convert images to both formats simultaneously. When serving images, browsers that support AVIF get the smallest file, while older browsers fall back to WebP or the original. AVIF conversion requires PHP 8.1+ with GD or ImageMagick AVIF support.

BoostPro automatically rewrites static asset URLs (images, CSS, JS, fonts, media files) to serve from your CDN instead of your origin server. Enter your CDN pull zone URL, choose which directories to include (defaults to wp-content and wp-includes), and optionally exclude specific URL patterns. Works with any pull-zone CDN provider like Cloudflare, BunnyCDN, KeyCDN, or StackPath.

The Resource Manager is a frontend tool that lets you disable any JavaScript or CSS asset on a per-page, per-post-type, or site-wide basis. Access it from the admin bar on any page. A slide-in panel shows every script and stylesheet loaded, grouped by source (plugins, theme, WordPress core). Toggle assets off, set scoping rules, and add exceptions. Includes a testing mode so changes only apply to logged-in admins until you're ready to go live.
