Responsive Image Builder

Suggest an improvement

Responsive image markup is easy to get subtly wrong. This builder inspects source dimensions, creates a width ladder and outputs copy-ready picture markup with lazy loading and async decoding.

/images/hero-480.webp 480w,
  /images/hero-768.webp 768w,
  /images/hero-1024.webp 1024w,
  /images/hero-1440.webp 1440w,
  /images/hero-1920.webp 1920w

This generates implementation code and naming plans. Pair it with Image Optimizer to create the actual files at each width.
