This plugin automatically adds specific HTML attributes to images and iframes on a site to improve loading performance. It is designed for site owners and developers looking to increase their site's speed and PageSpeed Insights score without manual coding.
Attribute Application: Adds loading="lazy" and decoding="async" attributes to <img> and <iframe> tags. This instructs browsers to load these elements more efficiently, which can reduce initial page load time.
Extended Coverage: Works on images outside standard content areas, such as those in custom headers or footers, where native lazy loading might not apply.
Scroll Performance Fix: Includes an optional script to address the PageSpeed Insights warning about passive listeners, which can improve scrolling smoothness.
Configuration Options: Provides settings to choose how attributes are applied (via filters or buffer) and allows you to disable lazy loading on specific images by adding a skip-lazy class.
Low Quality Image Placeholders (LQIP): Offers an optional function to display blurred placeholder images for post thumbnails while the full image loads, which can improve the Largest Contentful Paint metric.
