Optimazz

Optimazz is a WordPress plugin that serves as an all-in-one performance suite for website optimization and speedup. It targets improvements to Core Web Vitals by applying selected optimizations automatically and safely. The plugin is developed by Shipon Karmakar and is available through the official WordPress plugin directory.

It includes several opt-in and reversible modules. The page cache module serves static HTML instead of running PHP on every request and supports smart exclusions for logged-in users, carts, and query strings. It features automatic purging on content changes along with a cron-based cache preloader. The JavaScript module defers scripts and delays them until the first user interaction to reduce Total Blocking Time while maintaining an exclusion list. The CSS module minifies, combines, and loads stylesheets asynchronously to eliminate render-blocking resources. Image optimization covers lazy loading and WebP conversion. Additional modules address font optimization and database optimization.

Optimazz is delivered as a free plugin for WordPress sites. Every feature is designed to be modular so that it does not overwrite files from other caching plugins. The tool is intended for WordPress users seeking to improve site speed through these specific techniques.
