Raster graphics store images as a collection of pixels and are usually larger file sizes. They can be difficult to modify without quality loss. Examples include BMP, TIFF, GIF and JPEG. Vector graphics use geometric shapes and equations and can scale smoothly. Examples include AI, EPS and WMF. JPEG is best for small web images and allows varying compression quality versus file size. TIFF supports layers and compression without quality loss but results in large file sizes. PSD stores Photoshop files and layers but is only compatible with Photoshop. 3DS files contain 3D modeling data and geometry but do not support bones for animation.
