Our analysis

From the developer
Steve Truman's own description of a3 Lazy Load, lightly tidied.
a3 Lazy Load is a Mobile Oriented, very simple to use plugin that will speed up sites page load speed. The more content heavy your site the better the plugin will perform and the more you will see the improvements in performance. See this demo of a page with 1,000 images (yes 1,000 images) to load.
a3 Lazy Load is inspired by and powered by the ressio Lazy-Load-xt JavaScript.
100% compatable with WordPress 6.0
WordPress 5.5 introduced lazy loading for all images uploaded to a sites media library and 5.7 introduces Core lazy load for iframes and 5.9 contained performance enhancements. a3 Lazy Load Image options work side-by-side with these, but then enhances it by lazy loading all the images loaded from outside of the media library, or on older browsers that do not support the new WP attribute and any iframes or videos that are not lazy loaded by WordPress.
