One feature in Next.js that can significantly enhance web application performance with minimal effort is Automatic Image Optimization. This feature optimizes images on the fly, serving images in modern formats like WebP when supported by the browser, and automatically adjusting image sizes based on the device’s screen size and resolution. This reduces the amount of data transferred, improving load times and overall performance. Additionally, Next.js allows developers to specify image loading strategies, such as lazy loading, which further enhances performance by loading images only when they are within the viewport, reducing initial page load times.
