The importance of images on e-commerce, travel, and media websites has been increasing over the time. According to HTTP Archive, on an average, around 64% of a website’s weight is comprised of images. If we are able to reduce the size of these images without reducing the image quality, then it will have a direct and positive impact on page load speeds and user-experience of visitors on your websites.
