Mastering Next.js Image Optimization

Images are a critical part of modern web experiences, but they can also be a major source of performance bottlenecks. Next.js provides powerful built-in tools for optimizing images, making it easy to deliver fast, responsive, and high-quality visuals.

Why Image Optimization Matters

• Faster load times
• Better SEO
• Improved user experience

Using the Next.js <Image/> Component

The next/image component automatically optimizes images on demand. Here's a basic example:

import Image from 'next/image';

export default function Example() {
  return (
    <Image
      src="/images/hero.jpg"
      alt="Hero section image"
      width={800}
      height={400}
      priority
    />
  );
}
