Best Practices for Image Optimization
1. Choose the Right Image Format
- JPEG: Ideal for photographs and images with complex colors and gradients.
- PNG: Suitable for images with transparency or sharp edges, such as logos or icons.
- SVG: Best for vector graphics and scalable images that maintain quality across different resolutions.
Example: Selecting Image Formats
<img src="example.jpg" alt="Example Image" /> <!-- Use JPEG for photographs -->
<img src="logo.png" alt="Company Logo" /> <!-- Use PNG for logos with transparency -->
2. Optimize Image Sizes
- File Compression: Use tools to compress images without losing quality (e.g., TinyPNG, JPEG Optimizer).
- Resolution Adjustment: Resize images to match display requirements and reduce file size.

- Media Queries: Use CSS media queries to adjust image sizes and resolutions for various viewport sizes.
Example: Responsive Image Design
<img src="small.jpg" alt="Responsive Image" srcset="small.jpg 500w, medium.jpg 1000w, large.jpg 1500w" sizes="(max-width: 600px) 500px, 1000px" />
