Unused CSS—styles loaded but not used across your WordPress site on desktop—bloats pages, slows load times, and hurts SEO. Removing unused CSS in WordPress for desktop with WP Unload Assets trims this excess sitewide, speeds up rendering, and boosts Core Web Vitals like Largest Contentful Paint (LCP). This guide details how to remove unused CSS for all desktop pages, posts, and archives, with steps, screenshots, a video, and tips. For specific posts or pages, see our guides on post-specific CSS removal or page-specific CSS removal.
Why Remove Unused CSS in WordPress for Desktop?
Unused CSS, like a 50KB slider style on a desktop contact page, delays rendering and increases LCP. This harms user experience and SEO, as Google prioritizes fast desktop sites. Blocking 70KB of unused CSS can cut LCP by 0.8s across all desktop pages. WP Unload Assets’ “For Desktop” settings simplify this process, outperforming manual methods or plugins like WP Rocket.
Benefits of Removing Unused CSS with WP Unload Assets

Unremoved CSS bloats every desktop page, delaying LCP and interactivity. This leads to poor PageSpeed Insights scores, higher bounce rates (up to 15%), and lower rankings. Dynamic themes and plugins make manual removal risky. WP Unload Assets automates desktop-only sitewide CSS removal, ensuring safe optimization.
