Overview
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.

Mala idea adquirir la versión PRO
by davo342·2 months ago
Pague la versión PRO, y realmente fue un desastre, mi web tuvo constantes caídas, excesiva cantidad de cache, problemas con el CSS, realmente fue una perdida de dinero en el Plugin
Creates massive Cache. Sends mails.
by phalancs·4 months ago·1 reply
Today, I received an email from my minification plugin: Autoptimize wanted to tell me that there is sth. wrong with its cache. The plugin created a 900MB of cache data just within a week.
No plugin should be doing this. Also, I would never ever want to receive any any emails from my caching or minification plugin without my consent. There is sth. wrong there. Anyways, I don’t want a minification plugin like autoptimize just to still need to additionally install a proper caching plugin as well. Both should be integrated into one.
Disappointed.

It totally broke the CSS on my home page
by nakomarkov·4 months ago·1 reply
Immediately after the installation of Autoptimize my Home page became totally disordered – Menus, Images, elements. Only the home page was effected but after the plugin was removed the page left broken.
