Load Selected Stylesheets Without Blocking Rendering
Loads the stylesheets you choose in the background so they no longer delay the first paint, ideal for CSS of things below the fold like sliders or forms.
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 Key Scripts and Stylesheets by Handle
Adds preload hints for the enqueued scripts and stylesheets you name, so the browser fetches files that are discovered late (such as a slider script or icon font CSS) right at the start of the page load.
Remove Leftover Data From Uninstalled Plugins
Adds Tools > Leftover Plugin Data, where you enter a prefix (such as old_slider_) to see how many options, post meta, user meta and scheduled tasks use it, and delete them after reviewing the counts.
