What are Scaled Images?

It’s basically an image that has been scaled to match the exact size defined in CSS or HTML.

For instance, let’s say your source image is 400 x 400 but you want to display it at 40 x 40. To achieve this, first, browser will have to download this large file and then reduce its size to 40 x 40, which is the actual requirement.

This is an inefficient method as the browser has to download a large size picture than compute it to the smaller size, which may increase the load time of a website.

Opposed to this, the more efficient method should be rather than using 400 x 400 image, users must use the accurate required image size because when file size will be accurate, page will load faster and improve your website’s performance.
