How to Optimize Images for WordPress
Images are typically the largest assets on WordPress websites and are the primary cause of slow page load times. Properly optimized images can reduce your page size by 50-80% and dramatically improve load speeds.
WordPress 6.3 and later natively support WebP uploads. Combined with lazy loading and proper sizing, optimized images can transform your site performance and improve Google PageSpeed scores.
