Autoptimize vs NitroPack – Performance, Page Speed & Cache Plugin for Core Web Vitals, CDN & Image Optimization

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 think performance indeed is important, you should at least consider one of the many free page caching plugins (e.g. Speed Booster pack or KeyCDN’s Cache Enabler) to complement Autoptimize or even consider Autoptimize Pro which not only has page caching but also image optimization, CDN, critical CSS and more! Autoptimize Pro Autoptimize Pro is a premium Power-Up, adding image optimization, CDN, page caching, automatic critical CSS rules and extra “booster” options, all in one handy subscription to make your site even faster!!
