Blogger Responsive Picture Tag Generator

🛠 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.
