General Image Best Practices
Framework-agnostic techniques: WebP, AVIF, compression, CDN, and lazy loading strategies.
Image Optimization Best Practices
Modern Formats
- •Use WebP format: 30% smaller than JPEG/PNG with same quality, 95%+ browser support
- •Try AVIF format: 50% smaller than JPEG, growing browser support (85%+)
- •Provide fallbacks: Use <picture> element with multiple sources
Lazy Loading
- •Native lazy loading: Add loading="lazy" to images below the fold
- •Priority hints: Use fetchpriority="high" for LCP images
- •Intersection Observer: For advanced lazy loading with custom triggers
Responsive Images
- •Use srcset attribute: Serve appropriately sized images for different devices
- •Add sizes attribute: Help browsers choose the right image size
- •Art direction: Use <picture> for different crops on mobile/desktop
Compression & CDN
- •Compress images: Use tools like ImageOptim, Squoosh, or TinyPNG
- •Use image CDN: Cloudflare, Cloudinary, or Imgix for automatic optimization
- •Set cache headers: Cache-Control: max-age=31536000 for versioned images
Frequently Asked Questions
What is image optimization and why does it matter?
Image optimization reduces file sizes while maintaining visual quality. It matters because images are typically 50-70% of page weight. Optimized images improve Largest Contentful Paint (LCP), reduce bandwidth costs, and enhance user experience especially on mobile devices.
What are WebP and AVIF formats?
WebP and AVIF are modern image formats that provide 30-50% better compression than JPEG/PNG without quality loss. WebP has 95%+ browser support, while AVIF (newer) offers even better compression with growing browser support. Both should be used with fallbacks for older browsers.
How does lazy loading improve performance?
Lazy loading defers loading images until they're about to enter the viewport. This reduces initial page load time, saves bandwidth for users who don't scroll down, and improves Core Web Vitals scores. Use loading='lazy' attribute or JavaScript libraries for implementation.
Should I use a CDN for images?
Yes, CDNs serve images from servers geographically closer to users, reducing latency. Image CDNs like Cloudflare, Cloudinary, or Imgix also provide automatic format conversion, resizing, and optimization. This significantly improves load times globally.
What's the difference between compression and optimization?
Compression reduces file size by removing unnecessary data. Optimization includes compression plus format conversion (WebP/AVIF), proper sizing, lazy loading, responsive images (srcset), and caching. Comprehensive optimization can reduce image weight by 70-90%.
