2D graphics refer to images that have only two dimensions: width and height. These graphics are created using various software tools and can be found in many applications, such as video games, websites, and digital art. Common formats for 2D graphics include JPEG, PNG, and GIF. In contrast to 3D graphics, which add depth to images, 2D graphics are flat and often use techniques like shading and color to create the illusion of depth. Artists and designers use vector and raster graphics to produce 2D images, each with its own advantages and applications in visual media.
