Font smoothing is a technique used in digital typography to enhance the appearance of text on screens. It works by adjusting the colors of the pixels around the edges of letters, making them look less jagged and more visually appealing. This is especially important for smaller text sizes, where clarity can be compromised. Different operating systems, like Windows and macOS, use various methods for font smoothing. For instance, macOS employs a method called "subpixel rendering," which takes advantage of the screen's pixel layout to create smoother edges. This results in text that is easier to read and more aesthetically pleasing.
