What are Images?

    Raster Images

      Raster images are made of pixels. Pixels are the smallest objects that you can see on a screen. To create an image, pixels are stored in what is called a bitmap. Larger bitmap = larger image. i.e. 200 x 300 pixels. They blur when you zoom in too much because they only fit a particular resolution.

    Vector Images

      Vector images are made of mathematical commands that place lines and shapes. This allows them to take less space, since image data is stored in mathematical commands rather than bits. They wont be blurred when enlarged, because the commands adapt accordingly.

      You can convert vector images to raster images, and visa versa.

    Here is a comparism between vector and raster images(from vector-conversions.com):
