PDF (Portable Document Format) is one of the most popular formats used for storing document files which include both text and graphics. As opposed to other formats with a similar function, PDFs can be easily transferred between different applications and different operating systems, and generally don't have a very large size. Moreover, they can offer decent image quality in a compressed format and can be secured with passwords or watermarks.
