Cap the Largest Image Size in srcset
Stops browsers on large screens from downloading huge image versions by leaving very wide sizes out of the responsive srcset list.
Snippet Library
Performance snippets for WordPress
Snippets that make WordPress lighter and faster: remove emoji scripts and embeds, control the Heartbeat API, limit revisions and load scripts only where they are needed. For developers and site owners chasing better Core Web Vitals.
Preload Header for Your Theme Stylesheet
Sends an HTTP Link preload header for your theme's main stylesheet, so browsers, and CDNs that support Early Hints, start downloading the CSS before the HTML has even arrived.
Show Text Immediately While Google Fonts Load
Adds display=swap to every Google Fonts stylesheet your theme and plugins load, so text appears right away in a fallback font instead of staying invisible while the web font downloads.
