Covers the essentials for getting images web-ready: choosing between JPEG, PNG, WebP, and SVG based on content type, compressing with tools like ImageMagick and cwebp, and implementing responsive images with srcset. The reference guides walk through the full optimization pipeline from format selection to monitoring.
