Snippet Library
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.
Adds width and height attributes to images in your posts that lack them (for example images pasted from other sites or old posts), using the real image file size, which prevents layout jumps while pages load.
Adds Tools > Autoloaded Options showing the total size of options WordPress loads on every page and the 40 largest ones, with a button to stop autoloading any option that does not need it.
Stops browsers on large screens from downloading huge image versions by leaving very wide sizes out of the responsive srcset list.
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.
Adds Tools > Unused Image Sizes, which finds resized copies of your images made for sizes your current theme and plugins no longer register, shows how much space they take, and deletes them in batches after confirmation.
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.
