Images account for over 60% of the total bandwidth transferred on an average web page. If your website images are unoptimized, your site will load slowly, frustrate mobile visitors, and suffer lower rankings in Google Search results.
Key Steps for Complete Web Image Optimization
1. Right-Size Your Dimensions
Never upload raw 4000px images. Resize banner images to a maximum width of 1920px, and content images to 800px or 1200px.
2. Adopt Modern WebP & AVIF Formats
Serving WebP images instead of heavy JPEGs cuts overall page payload size significantly.
3. Implement Lazy Loading (`loading="lazy"`)
Add `loading="lazy"` attributes to images below the fold so browsers load them only when the user scrolls down.
