Sometimes you may come across popular raster graphic formats that contain more than a simple image. It's also worth noting that many popular graphic design software tools like Adobe Illustrator, Photoshop can handle both raster and vector graphics.

Popular vector graphic file formats include SVG, AI, PDF and EPS. The most popular raster graphic file formats include JPEG, PNG, and GIF.
This is another reason some service providers will request vector files, as vector images are more compressed and thus easier to transfer and store. The higher the pixels per inch (PPI) or dots per inch (DPI), the higher the clarity, but the file will be larger and will take up more storage space. Raster graphics, because they are made of pixels, can amount to quite a large file size.
While raster graphics are best for photographs and other types of images with continuous tones, when working with illustrations and graphics with clean lines and shapes, it’s best to use vector graphics. Raster graphics only retain quality if they are scaled down, but when a raster graphic is enlarged it becomes pixelated, and can look grainy or less clear. This makes vector files incredibly versatile, as a small image viewed on your screen can be scaled to the size of a billboard and remain just as clear. The main practical difference in the two types is that vector graphics can be scaled without any loss of quality. Vector graphics are made up of curves that form paths and shapes, defined by mathematical equations. Raster graphics are also known as bitmap graphics, and are made of thousands of tiny pixels arranged in a grid to form an image.
