Why Reducing Image Size Matters

Before we dive into the tools, it’s important to understand why image optimization is crucial.

2. SEO ranking – Google prioritizes fast websites, and optimized images directly contribute to speed improvements.

3. Better user experience – Visitors expect quick browsing. Compressed images keep your pages smooth and responsive.

4. Storage savings – Smaller images save space whether you're working on a personal device or cloud platform.

5. Faster sharing – Files upload faster to social media, email, and collaboration tools.
