Image optimization is crucial for web performance. Here are the key strategies:

1. Choose the right format: Use WebP for modern browsers, JPEG for photos, PNG for graphics with transparency.

Modern image formats provide better compression

2. Compress images: Reduce file size while maintaining quality using tools like CompressorPic.

3. Use responsive images: Serve different sizes for different screen sizes.

Responsive images adapt to different screen sizes

4. Implement lazy loading: Load images only when they're about to enter the viewport.

5. Consider CDN: Use a Content Delivery Network to serve images faster.

By following these practices, you can significantly improve your website's loading speed and user experience.
