Autoptimize free WordPress plugin

Autoptimize makes optimizing your site really easy. It can aggregate, minify and cache scripts and styles, injects CSS in the page head by default but can also inline critical CSS and defer the aggregated full CSS, moves and defers scripts to the footer and minifies HTML. You can optimize and lazy-load images (with support for WebP and AVIF formats), optimize Google Fonts, async non-aggregated JavaScript, remove WordPress core emoji cruft and more. As such it can improve your site’s performance even when already on HTTP/2! There is extensive API available to enable you to tailor Autoptimize to each and every site’s specific needs.
If you consider performance important, you really should use one of the many caching plugins to do page caching. Some good candidates to complement Autoptimize that way are e.g. Speed Booster pack, KeyCDN’s Cache Enabler, WP Super Cache or if you use Cloudflare WP Cloudflare Super Page Cache.
