Smaller images, faster pages

Images are usually the heaviest part of a web page, an email attachment or a document upload. Two settings decide most of the file size: the pixel dimensions and the compression format. Shrinking a phone photo to the size it will actually be displayed at, and saving it in a suitable format, often makes it many times smaller with no visible change.
