<Image>

The <Image> component extends the HTML <img> element with automatic image optimization, including resizing, format conversion (WebP/AVIF), and lazy loading.

app/page.js

import Image from 'next/image'

export default function Page() {
  return (
    <Image
      src="/profile.png"
      width={500}
      height={500}
      alt="Picture of the author"
    />
  )
}

Props

string

required

The source of the image. Accepts:

An internal path string: "/profile.png"
An absolute external URL (must be configured with remotePatterns): "https://example.com/image.png"
A static import: import profile from './profile.png'

The default loader does not forward request headers when fetching src. If your image requires authentication, use unoptimized to bypass optimization.

string

required

Describes the image for screen readers and search engines. Also shown as fallback text if the image fails to load.The text should replace the image without changing the meaning of the page. It does not supplement captions. For purely decorative images, use an empty string: alt="".

number

The intrinsic width of the image in pixels. Used to infer the aspect ratio and prevent layout shift. Does not determine the rendered size — use CSS for that.Required unless the image is statically imported or has fill={true}.

number

The intrinsic height of the image in pixels. Used to infer the aspect ratio and prevent layout shift. Does not determine the rendered size — use CSS for that.Required unless the image is statically imported or has fill={true}.

boolean

default:"false"

Expands the image to fill its parent element. The parent must have position: relative, fixed, or absolute. The <img> element defaults to position: absolute.Use objectFit to control how the image fills the container:

"contain" — scales down to fit while preserving aspect ratio
"cover" — fills and crops the container

string

A string that maps viewport widths to image sizes, used by the browser to select the best srcset entry.

<Image
  fill
  src="/example.png"
  sizes="(max-width: 768px) 100vw, (max-width: 1200px) 50vw, 33vw"
/>

Use sizes when:

The image uses the fill prop
CSS makes the image responsive

Without sizes, the browser assumes the image is full viewport width and may download unnecessarily large images.

number

default:"75"

Image quality from 1 to 100. Higher values increase file size. Must match a value in the qualities config array (required in Next.js 16+).

boolean

default:"false"

When true, inserts a <link rel="preload"> in the <head> to fetch the image early.Use for LCP (Largest Contentful Paint) images, such as hero images above the fold. Do not combine with loading or fetchPriority.

Added in Next.js 16. Replaces the deprecated priority prop.

string

default:"lazy"

Controls when the image loads:

"lazy" — defers loading until near the viewport
"eager" — loads immediately regardless of position

string

default:"empty"

Placeholder shown while the image loads:

"empty" — no placeholder
"blur" — blurred version; requires blurDataURL
"data:image/..." — a Data URL used directly as the placeholder

string

A Data URL used as a blur-up placeholder when placeholder="blur". Should be a very small image (10px or less) — it is enlarged and blurred automatically.Automatically set for statically imported jpg, png, webp, and avif images (unless animated). For dynamic or remote images, provide this manually.

object

Inline CSS styles passed to the underlying <img> element.

<Image
  src="/profile.png"
  alt="Profile"
  style={{ borderRadius: '50%', width: '100px', height: 'auto' }}
/>

If you set a custom width via style, also set height: 'auto' to preserve the aspect ratio.

function

A custom function to generate image URLs. Receives { src, width, quality } and returns a URL string.

'use client'

const imageLoader = ({ src, width, quality }) => {
  return `https://example.com/${src}?w=${width}&q=${quality || 75}`
}

export default function Page() {
  return (
    <Image loader={imageLoader} src="me.png" alt="Me" width={500} height={500} />
  )
}

Props that accept functions, like loader, require a Client Component.

boolean

default:"false"

When true, serves the image as-is from src without changing quality, size, or format. Useful for small images, SVGs, and animated GIFs.

string

Overrides the src attribute on the rendered <img> element while keeping the generated srcset. Useful when migrating from <img> to <Image> and needing to preserve the original URL for SEO.

string

default:"async"

Hint to the browser for image decoding strategy:

"async" — decode asynchronously; other content renders first
"sync" — decode synchronously for atomic presentation
"auto" — browser chooses

function

Callback invoked when the image finishes loading and the placeholder is removed. Receives the native event with event.target pointing to the <img> element.

Requires a Client Component.

function

Callback invoked if the image fails to load.

Requires a Client Component.

Deprecated props

boolean

deprecated

Deprecated in Next.js 16. Use preload instead.

function

deprecated

Deprecated in Next.js 14. Use onLoad instead.

Configuration

You can configure image behavior globally in next.config.js under the images key.

`remotePatterns`

Defines allowed remote image sources. Any image from a URL not matching these patterns returns a 400 error.

next.config.js

module.exports = {
  images: {
    remotePatterns: [
      {
        protocol: 'https',
        hostname: 's3.amazonaws.com',
        port: '',
        pathname: '/my-bucket/**',
        search: '',
      },
    ],
  },
}

Alternatively, use a URL object shorthand:

next.config.js

module.exports = {
  images: {
    remotePatterns: [new URL('https://example.com/account123/**')],
  },
}

Wildcard patterns:

* matches a single path segment or subdomain
** matches any number of path segments at the end, or subdomains at the beginning

`localPatterns`

Restricts which local paths can be optimized.

next.config.js

module.exports = {
  images: {
    localPatterns: [
      {
        pathname: '/assets/images/**',
        search: '',
      },
    ],
  },
}

`formats`

Output image formats in preference order. Defaults to ['image/webp'].

next.config.js

// Enable AVIF with WebP fallback
module.exports = {
  images: {
    formats: ['image/avif', 'image/webp'],
  },
}

`deviceSizes`

Device width breakpoints used to generate responsive srcset entries.

next.config.js

module.exports = {
  images: {
    deviceSizes: [640, 750, 828, 1080, 1200, 1920, 2048, 3840],
  },
}

`imageSizes`

Additional image widths concatenated with deviceSizes for images that use the sizes prop.

next.config.js

module.exports = {
  images: {
    imageSizes: [32, 48, 64, 96, 128, 256, 384],
  },
}

`qualities`

Allowlist of permitted quality values. Required in Next.js 16+.

next.config.js

module.exports = {
  images: {
    qualities: [25, 50, 75, 100],
  },
}

`minimumCacheTTL`

Time-to-live (in seconds) for cached optimized images. Defaults to 14400 (4 hours).

next.config.js

module.exports = {
  images: {
    minimumCacheTTL: 2678400, // 31 days
  },
}

`loaderFile`

Path to a custom image optimization loader, relative to the project root.

next.config.js

module.exports = {
  images: {
    loader: 'custom',
    loaderFile: './my/image/loader.js',
  },
}

`getImageProps`

Returns the props that <Image> would pass to the underlying <img> element without rendering the component. Useful for art direction, background images, and canvas.

app/page.js

import { getImageProps } from 'next/image'

export default function Home() {
  const common = { alt: 'Art direction example', sizes: '100vw' }
  const { props: { srcSet: desktop } } = getImageProps({
    ...common, width: 1440, height: 875, quality: 80, src: '/desktop.jpg',
  })
  const { props: { srcSet: mobile, ...rest } } = getImageProps({
    ...common, width: 750, height: 1334, quality: 70, src: '/mobile.jpg',
  })

  return (
    <picture>
      <source media="(min-width: 1000px)" srcSet={desktop} />
      <source media="(min-width: 500px)" srcSet={mobile} />
      <img {...rest} style={{ width: '100%', height: 'auto' }} />
    </picture>
  )
}

Examples

Local image

Statically imported images have their width and height inferred automatically.

app/page.js

import Image from 'next/image'
import mountains from '../public/mountains.jpg'

export default function Page() {
  return (
    <Image
      src={mountains}
      alt="Mountains"
      sizes="100vw"
      style={{ width: '100%', height: 'auto' }}
    />
  )
}

Remote image

Provide width and height explicitly since Next.js cannot inspect remote files at build time.

app/page.js

import Image from 'next/image'

export default function Page({ photoUrl }) {
  return (
    <Image
      src={photoUrl}
      alt="Photo"
      sizes="100vw"
      style={{ width: '100%', height: 'auto' }}
      width={500}
      height={300}
    />
  )
}

Fill layout

Use fill when the image dimensions are unknown. The parent container must be positioned.

<div style={{ position: 'relative', width: '400px', height: '300px' }}>
  <Image
    src="/photo.jpg"
    alt="Photo"
    fill
    sizes="(min-width: 808px) 50vw, 100vw"
    style={{ objectFit: 'cover' }}
  />
</div>

Blur placeholder

<Image
  src="/hero.jpg"
  alt="Hero"
  width={1200}
  height={600}
  placeholder="blur"
  blurDataURL="data:image/jpeg;base64,..."
/>

For statically imported local images, blurDataURL is set automatically.

Background image

app/page.js

import Image from 'next/image'
import mountains from '../public/mountains.jpg'

export default function Background() {
  return (
    <Image
      alt="Mountains"
      src={mountains}
      placeholder="blur"
      quality={100}
      fill
      sizes="100vw"
      style={{ objectFit: 'cover' }}
    />
  )
}
