Pros WebP conversion and bulk optimisation in the free version; Local server tools or cloud API optimisation; Works with NextGEN Gallery and Flagallery libraries Converts images to WebP and AVIF on upload or in bulk; Resizing and compression from the WordPress media area
Cons Higher optimisation levels need a paid API key; Some CDN and cloud features call the vendor's servers Needs an Elementor account connection before optimisation runs; Upgrade prompts and licence checks tie full use to a paid plan
