Optimizing Images for a NextJS project

Image optimization in NextJs

How to optimize images

The Next.js <Image> component extends the HTML <img> element to provide:

  • Size optimization: Automatically serving correctly sized images for each device, using modern image formats like WebP.

  • Visual stability: Preventing layout shift automatically when images are loading.

  • Faster page loads: Only loading images when they enter the viewport using native browser lazy loading, with optional blur-up placeholders.

  • Asset flexibility: Resizing images on-demand, even images stored on remote servers.

To start using <Image>, import it from next/image and render it within your component.

import Image from 'next/image'

export default function Page() {

return <Image src="" alt="" />

}
