WPML

Autoptimize is fully compatible with WPML. Autoptimize aggregates, minifies, and caches your scripts and style files to speed up how your pages load, which helps both search rankings and the visitor experience. It optimizes every language version of your WPML site the same way, so a multilingual site loads as fast as a single-language one.

Autoptimize is a free plugin that specializes in optimizing your site’s HTML, CSS, and JavaScript code. This can greatly improve your site’s speed, your search engine ranking, and your site’s user experience.

Autoptimize works by aggregating, minifying, and caching scripts and style files. It also optimizes images and Google Fonts and enables lazy loading. This means your page is not only smaller, but it also reduces the number of requests to the server. The page takes a shorter amount of time to load, and the page load speed and rendering are faster.

Please note: Autoptimize does best when paired with a caching plugin to provide even better performance.
