Static Assets

Next.js can serve static files, like images, under a folder called public in the root directory. Files inside public can then be referenced by your code starting from the base URL (/).

For example, if you add me.png inside public, the following code will access the image:

import Image from 'next/image'
export function Avatar() {
  return <Image src="/me.png" alt="me" width="64" height="64" />

For static metadata files, such as robots.txt, favicon.ico, etc, you should use special metadata files inside the app folder.

Good to know:

  • The directory must be named public. The name cannot be changed and it's the only directory used to serve static assets.
  • Only assets that are in the public directory at build time will be served by Next.js. Files added at request time won't be available. We recommend using a third-party service like AWS S3 for persistent file storage.
