Optimizing images is crucial for improving WordPress website speed. Since one image can be larger than all your CSS and JS files combined, it can significantly impact your website’s performance. Using modern image formats such as WebP and AVIF, and implementing lazyloading can help optimize images for faster load times.
To further optimize images for WordPress speed, it is important to use the correct image dimensions instead of relying on CSS to resize them. Using the appropriate dimensions can reduce the image file size, improve load times, and prevent layout shifts on the webpage.
