Image Optimization

Image optimization is the process of reducing the file size of images while maintaining acceptable visual quality, to improve website performance, user experience, and SEO. It involves techniques like compression, format selection, responsive sizing, and lazy loading. This is crucial for web development as images often account for the majority of page weight.
