Larger images are usually saved as progressive because they take up less space this way, while smaller images remain baseline.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to add lazy loading to ShortPixel-optimized images<\/h2>\n\n\n\n<p>Since ShortPixel Image Optimizer does not provide lazy loading, you can use a separate plugin like <strong>Autoptimize<\/strong> to enable it:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Install and activate <strong>Autoptimize<\/strong>.<\/li>\n\n\n\n<li>Go to <strong>Settings > Autoptimize > Images<\/strong>.<\/li>\n\n\n\n<li>Enable the checkbox <strong>\u201cLazy-load images?\u201d<\/strong>.<\/li>\n<\/ol>\n\n\n\n<section class=\"callout-blue\">Note: If you enable \u201cOptimize Images\u201d in Autoptimize, images will be served from ShortPixel\u2019s CDN.
