How does image compression improve Core Web Vitals?

Image compression directly reduces LCP (Largest Contentful Paint) by making the largest image on the page load faster. Google uses LCP as a ranking factor. Compressing hero images from 500KB to under 100KB can improve LCP from Poor to Good.

What image quality should I use for website images?

Set JPEG quality to 75-85% for most web images. At 80%, file sizes are reduced by 60-75% with no visible quality difference on screen. For thumbnails, 70% is acceptable. For hero images, use 85% to preserve sharpness.

Should I use JPEG or WebP for my website?

WebP is the best choice for modern websites - it produces 25-35% smaller files at the same visual quality as JPEG. All modern browsers support WebP. JPEG remains a safe fallback for older browsers.

Does compressing images affect SEO?

Yes, positively. Faster page loads improve Core Web Vitals which Google uses for rankings. Compressed images improve crawl efficiency and user engagement - both positive SEO signals.
