Images are a powerful part of any website, helping to capture attention and improve user experience. But when images are too large or not properly optimized, they can slow down your site and negatively impact SEO rankings.

That’s why choosing the right image format and using proper compression techniques is essential. Formats like PNG, JPG, WebP, and GIF each serve a different purpose, and knowing when to use them can significantly improve performance.

In this guide, you’ll learn how to convert and optimize images for faster loading speeds and better SEO results.
