When you create a website you add Images to give make it interactive for the visitors. Images consist of useless comments and colors that make the website’s performance slow. You can use JPEG format when compressing images. If you will optimize the size of images, you can increase the speed of a website. You can also use different types of plugins available depending on which software you are using. For example, there is a plugin for Word press ‘WP Smush.it’ which you can use to compress the images of a website.
