Some of the common problems caused by unoptimized images include:
- Slower load times - Increased bandwidth usage - Lower ranking in search engine results
Hence, every developer needs to ensure that images are well optimized in their NextJS apps.
Effective Techniques for Image Optimization in NextJS
NextJS has embedded capabilities and additional tools that you can use to optimize image handling in your applications. Here are some efficient techniques that can help streamline your image optimization process.
Leveraging the NextJS Image Component
As of version 10, NextJS provides a built-in Image Component and Automatic Image Optimization. The Image Component is an extension of the HTML `img` element, replacing it with improved performance. It optimizes images on-demand, as users request them. Once an image is loaded by a user in a specific browser, it reloads only if the `src` property changes. Image optimization works with any image source, and therefore, you can use it with images hosted on your file system, a CMS, or even a CDN.
Let us dive into how to use this component:
```jsx
import Image from 'next/image'
function MyComponent() {
return (
export default MyComponent
```
Subscription successful.
Using Multiple Image Formats
Different browsers support different formats of images. NextJS allows you to use modern efficient formats like WebP when the browser supports it. If the browser doesn’t support a particular format, NextJS provides the image in a format that the browser does support.
To make multiple formats available for a single image, you can use the `srcSet` property with the Image component. Here’s an example:
```jsx
import Image from 'next/image'
function MyComponent() {
return (
Different formats for the same image
export default MyComponent
```
