Bitmap vs Vector What is DPI? Bitmaps are images that are made up of small squares or "pixels". Once a bitmap is created the number of pixels in the image can never increase which means when you make the image bigger or zoom in, the quality of that image will decrease. Vector images are created simply by using x and y coordinates. Shapes are created by using points and lines. This is why you can scale up or zoom in to a vector image as much as you need without losing image quality. Usual Bitmap file extensions are: bmp, jpg, psd, tiff, png, and gif. Usual Vector file extensions are: ai, eps, and sometimes pdf. DPI stands for dots per inch. The more dots a images has per inch the better it will look when it is printed. Most images from the web are at 72 dpi, which is not acceptable when printing. For a bitmap image to be printed in high quality it must be at least 150 dpi if not 300. The two text images below are set a different dpi's. The left is 72 dpi and the right is 300. If one looks closely, especially at the curves of the letters they can see that the 72 dpi image has jagged edges, while the 300 dpi images are not.
