Load comment-reply.js Only When Needed
Stops the threaded comments script from loading on pages that have no open comments or where threading is turned off.
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.
Load the WooCommerce Password Strength Meter Only When Needed
Removes the password strength meter script (about 400 KB with its dictionary) from every page except the account, checkout and password reset pages where customers actually choose a password.
Log Pages That Run Too Many Database Queries
Records front-end URLs that run more database queries than a limit you set, with the query count and load time, and lists the worst offenders under Tools > Heavy Pages.
Log Slow Outgoing HTTP Requests
Times every request your site makes to other servers (update checks, APIs, license servers) and records the ones slower than a second under Tools > Slow HTTP Calls, so you can find what is holding up page loads.
Move Selected Scripts to the Footer
Moves the scripts you list from the page head to the footer, so they stop blocking the page from rendering.
Page Weight Summary in the Admin Bar
Shows an admin bar item on the front of the site with the total size of the page's scripts, stylesheets, images and fonts, and a breakdown with the heaviest files when you click it.
Prefetch the Next Page of Archives and Paginated Posts
Adds a prefetch hint for the next page of blog archives, category pages and multi-page posts, so it opens almost instantly when visitors click "Next".
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.
Preload a Chosen Hero Image per Page
Adds a "Preload hero image" field to the post and page editor; when filled in with an image URL, that image is preloaded with high priority on that page, improving Largest Contentful Paint for pages whose main image is not the featured image.
Preload the Featured Image on Single Posts
Tells the browser to fetch the featured image of the current post or page right away, which improves Largest Contentful Paint when it is shown at the top.
Preload the Site Logo
Preloads the logo set in the theme or Site Editor so it appears with the first paint of the header.
Prerender Links on Hover
Upgrades WordPress speculative loading (6.8+) from prefetch to prerender with moderate eagerness, so pages open almost instantly after a hover.
Raise the Memory Limit for Admin Tasks
Gives memory-hungry admin tasks like image processing and imports more room, without raising the limit for every front-end visit.
Remove Block Styles on Classic Themes
Stops the block library, classic theme and global styles stylesheets from loading on the front end. For classic themes and page builders that do not use blocks.
Remove Block Theme Styles From Classic Themes
Stops classic (non-block) themes from loading the global styles, classic theme styles and duotone SVG filters that WordPress adds for block themes, saving inline CSS on every page.
Remove jQuery Migrate on the Front End
Drops the jQuery Migrate compatibility script from public pages. Only use it when your theme and plugins work with current jQuery.
Run WP-Cron From a Real Cron Job
Stops WordPress from checking for scheduled tasks on every page view; you trigger wp-cron.php from your server's cron instead, which is faster and more reliable.
Serve Media and Static Files From a CDN Domain
Rewrites the URLs of your uploads, theme and plugin files to a CDN or pull-zone domain you set, so images, CSS and JavaScript are delivered from the CDN while pages are still served by your site.
Server-Timing Header for Administrators
Adds a Server-Timing header with PHP time, database query count and peak memory to pages viewed by administrators, so you can read the numbers in your browser's developer tools Network tab.
Site Health Check for Compression and Browser Caching
Adds a Site Health test that requests your homepage and one of your theme's stylesheets and reports whether text files are compressed (gzip or Brotli) and whether static files get long browser cache lifetimes.
Skip PDF Preview Images on Upload
Stops WordPress from generating preview images for every uploaded PDF, which speeds up uploads and saves disk space.
Skip Rendering Off-Screen Comments and Footers Until Needed
Uses the CSS content-visibility property so browsers skip laying out the comments section, footer and related posts until the visitor scrolls near them, which speeds up rendering of long pages.
Stop Crawlers Paging Endlessly Through Old Archives
Returns a "not found" page for archive pages beyond page 50 (such as /page/873/) for logged-out visitors, which keeps bots from hammering your database with very slow deep pagination queries.
Stop Elementor From Loading Google Fonts
Prevents Elementor from requesting fonts from Google's servers, for faster pages and fewer third-party connections.
