Test Post 8: Image Optimization for the Web
Why Image Optimization Matters
Images account for nearly 50% of a typical web pages total size. Optimizing them can dramatically improve load times and user experience.
Choosing the Right Format
- WebP: Best all-around format for photos and graphics
- AVIF: Next-gen format with even better compression
- SVG: Perfect for logos and icons
- PNG: Use only when you need transparency with no quality loss
Compression Techniques
Lossy compression reduces file size by removing some data. For most web images, a quality setting of 80% is visually indistinguishable from 100%.
Responsive Images
Serve different image sizes for different screen sizes using the srcset attribute. This prevents mobile users from downloading desktop-sized images.
