Images can make or break your website.
Heavy, unoptimized images slow everything down, hurt SEO, and frustrate users. Optimized images, on the other hand, load fast, look sharp, and improve conversions.

🚀 What Is Image Optimization?
Image optimization is the process of:

- Preparing images for web or sharing
👉 Goal: Fast loading + high quality
🧩 Step 1: Choose the Right Image Format
