Image Optimization is that process where you need to build or deliver high-quality images in the right format and size to the website, and this way it will help with the website's page loading speed, website SEO ranking, etc. You also need to add keywords to the images and you can do that through the Alt+Images tag.

Optimizing web images is a process of delivering high-quality images in the right format, dimension, size, and resolution while keeping the smallest possible size. Image optimization can be done in different ways, be it by resizing the images, caching, or by compressing the size.

image optimization is 2 things. First would be seo of images for better results in search engines. You do this with image alt tags they describe the image and use keyword to describe it. The next would be to make image load fast and no slow down website speed so you have a fast loading website and low bounce rate.

Search engines now look at page speed so keep images and videos to a minimum on each page. You can use thumbnail for smaller images on page and host larger one on another page if need be. You reduce the bandwidth used by your website on you hosting package with images that are optimized.
