Guide to resizing images with next.js

I have an issue with resizing an image within a Bootstrap card using next/image. I am trying to decrease the size of the image to about 60% of its original size and prevent it from filling the entire top portion of the card. I attempted wrapping the image in a div container and applying some CSS styles, but unfortunately, it did not change the size as expected.

import Image from 'next/image'
import logo from '../public/delta-logo.png'
import { Card, Button } from 'react-bootstrap'
import styles from './landing.module.css'

import 'bootstrap/dist/css/bootstrap.min.css'

export default function LandingPage() {
  return (
    <Card style={{ width: '18rem' }}>
      <Image src={logo} alt='Picture of our Logo' />

      <Card.Body className='text-center'>
        <Card.Title>Card Title</Card.Title>
        <Card.Text>
          Some quick example text to build on the card title and make up the
          bulk of the card's content.
        </Card.Text>
        <Button variant='primary'>Go somewhere</Button>
      </Card.Body>
    </Card>
  )
}

Answer №1

To resize an image, you have two options:

<Image src={logo} alt='Picture of our Logo' width={500} height={500}/>

OR

You can create a CSS class for your image and apply it using the className attribute like this:

<Image src={logo} alt='Picture of our Logo' className='yourClass'/>

Answer №2

  1. To further optimize, consider using the following option in your Next.config.js file: [image-optimization-nextjs][1] [1]: https://nextjs.org/docs/basic-features/image-optimization#loader

  2. You can avoid importing images directly onto your page. The next/image component automatically recognizes the images in the /public directory with src="/delta-logo.png"

  3. Additionally, you have the option to specify width and height properties within the Image tag.

Answer №3

To adjust the image size, I utilized the following method:

<div className="relative w-[50px] h-[50px] md:w-[100px] md:h-[100px]">
   <Image src="/images/myImage.png" alt="logo" fill />
</div>

Make sure to enclose the <Image> tag within a <div> element, specify the 'relative' positioning for the div, and modify the image dimensions by utilizing Tailwind CSS classes. Also, don't forget to include the 'fill' property in the <Image> tag.

Answer №4

The latest update to NextJS includes a new feature called "sizes", which aims to provide detailed information about image sizes in various device breakpoints.

import Image from 'next/image'

// ... Your code
 
export default function Page() {
  return (
    <div className="grid-element">
      <Image
        fill
        src="/example.png"
        sizes="(max-width: 768px) 100vw, (max-width: 1200px) 50vw, 33vw"
      />
    </div>
  )
}

// ...Your code

In addition, you have the option to optimize images for production by installing the sharp module using npm install sharp.

For more information, refer to the NextJS Docs.
