Image Optimization
Images can significantly impact website loading times. Optimize them by:
- Reducing file size by compression: Use tools like Imagemin or webpack plugins to compress images without sacrificing quality.
- Choosing the right format: Use JPEG for photos, PNG for graphics with transparency, and WebP for a modern format with better compression.
- Lazy loading images: Only load images when they appear in the viewport, using libraries like react-lazy-load-image.
