How to Optimize Images for Core Web Vitals
March 10, 2026
What are Core Web Vitals? Core Web Vitals are a set of metrics that measure user experience on your website. They include Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
Image Impact on LCP: Images are often the largest element on a page and directly affect LCP. Optimizing images can significantly improve your LCP score.
Optimization Techniques: Use modern formats like WebP. Implement lazy loading for below-the-fold images. Specify image dimensions to prevent CLS. Use responsive images with srcset. Our image compressor tool helps you implement these optimizations easily.
