🛠 What this tool does

The Responsive Picture Tag Generator helps Blogger users create SEO-friendly, responsive <picture> tags for images hosted on Blogger.
By default, Blogger adds fixed-size image URLs in posts, which often leads to SEO and performance issues such as:

  • 🔺"Improve image delivery" 
  • 🔺"Largest Contentful Paint element"
  • 🔺"Properly size images"
  • 🔺"LCP request discovery"
  • 🔺"Image elements do not have explicit width and height"

This tool solves those problems by automatically generating a <picture> tag that serves:
✅ Smaller images on mobile
✅ Larger images on desktop
✅ A properly sized fallback image — all using the modern WebP format.


Why use it

  • Optimizes your images for faster loading across devices.
  • Helps improve Core Web Vitals scores (especially LCP).
  • Fixes common SEO warnings from tools like Google PageSpeed Insights.
  • Keeps your blog lightweight and user-friendly — without any coding.
