Optimize Your Website with Better Images

Published on January 10, 2025

Website performance is crucial for user experience and SEO rankings. Images are often the largest assets on a website, and optimizing them can dramatically improve load times and overall performance metrics.

The Impact of Image Optimization

Studies show that every second of delay in page load can result in a 7% loss in conversions. Properly optimized images can reduce page load time by up to 50%, significantly improving user satisfaction and search engine rankings.

Key Optimization Techniques

  • Compression: Reduce file size without sacrificing quality
  • Right Dimensions: Use appropriately sized images for each context
  • Modern Formats: Use WebP format when browser support allows
  • Lazy Loading: Load images only when visible in viewport

Recommended Image Sizes

  • Hero Images: 1200-1600px wide, 200-500 KB
  • Content Images: 800px wide, 100-300 KB
  • Thumbnails: 300-400px wide, 30-100 KB
  • Icons: 64-128px, 5-20 KB

Performance Metrics

Use tools like Google PageSpeed Insights to measure the impact of your image optimization. Aim for:

  • Largest Contentful Paint (LCP): under 2.5 seconds
  • Cumulative Layout Shift (CLS): under 0.1
  • First Input Delay (FID): under 100ms
