Introduction: Why Image Optimization?
In the modern web environment, website performance is directly linked to business success. According to Google, as page load time goes from 1s to 3s, the probability of bounce increases by 32%. Given that images account for 60-70% of average page weight, optimization is the most cost-effective strategy.
4-Step Optimization Strategy
1. Proper Resizing
Serving a 4000px image in a 400px container is a common mistake. Always resize images to at most 2x the display size for Retina displays.
2. Next-Gen Formats (WebP & AVIF)
WebP offers ~30% better compression than JPEG. AVIF is even more efficient. Use tools like Re-Sizefy to convert your library.
3. Intelligent Compression
Use lossy compression for photographs to save up to 80% space without visible quality loss. Use lossless for logos and text-heavy images.
4. Lazy Loading & Preloading
Use loading="lazy" for below-the-fold content and rel="preload" for hero images to improve LCP.
Conclusion
Image optimization should be a standard part of your workflow to save server costs and improve SEO rankings.
