There is two main type of digital graphics files -First one is Raster Images and second is Vector.
Vector images are made of thousands of small points that unite together to make lines and curves to create vector graphics. Basically, Vector graphics are based on mathematical calculations define geometric primitives such as lines, circles, polygons, curves, and rectangles. There are some well-known applications that deal with vector-based graphics are:
Used In- Vector images are mainly used for illustration, logos, technical drawing, CAD, Engineering, and also used in 3D graphics.

Pros of Vector Images-
Cons of Vector images- Vector images are not very good for continuous tone images that blend with multiple shades of color.
Raster images are pixel-based images that are created with pixel-based programs or captured with a camera or scanner. A smallest single element of the display device is known as a pixel. If you zoom into a raster image, you will be able to see the square. Raster format is resolution-specific
Used In- The most commonly used type of raster graphics is “a photograph”. Raster graphics are most suitable for non-line art images. Images that we find on websites are raster images. Raster images are good for digital work rather than printing work.
File Formats-
The most common raster image format are :
