Click-to-Play YouTube Embeds
Shows a lightweight thumbnail instead of the full YouTube player until the visitor clicks play, saving around a megabyte of scripts per video.
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.
Collect Real Core Web Vitals From Your Visitors
Measures Largest Contentful Paint, Cumulative Layout Shift and Interaction to Next Paint in visitors' browsers and shows the 75th percentile of the last 7 days per page type in a dashboard widget.
Convert MyISAM Database Tables to InnoDB
Run on demand to convert your site's remaining MyISAM tables to InnoDB, the modern MySQL engine that handles many visitors at once far better and survives crashes more safely.
Database Table Sizes and Optimize Buttons
Adds Tools > Database Tables listing every table of your site with its row count, data and index size and reclaimable space, sorted by size, with an Optimize button for tables that need it.
Do Not Lazy-Load the First Images
Tells WordPress to skip lazy loading for the first three images on a page, which usually improves Largest Contentful Paint.
Inline Critical CSS From Your Theme
Prints the contents of a critical.css file from your active theme folder directly in the page head, so above-the-fold content is styled before the main stylesheet finishes loading.
Load Contact Form 7 Assets Only Where a Form Is Used
Keeps Contact Form 7 scripts and styles off every page except those that contain a form, removing two requests from most pages.
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.
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.
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.
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 Expired Login Sessions From the Database
Once a day, removes expired login sessions that WordPress keeps in user meta until the user logs in again, which on membership sites and shops adds up to a lot of dead data.
Send Emails in the Background
Queues emails sent by WordPress and plugins and sends them a few seconds later through WP-Cron, so form submissions, orders and registrations no longer wait for the mail server.
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.
Skip Loading Translations on English Sites
Stops WordPress, plugins and themes from loading translation files on the front end (or everywhere) to save memory and time on sites whose visitors read English anyway, with a list of text domains to keep.
