If the sender sends a PDF, he or she has full confidence that the recipient will be able to read the file.
The PDF was the first file format that enabled a document to be shared electronically while retaining all elements of its original formatting. Since its birth in 1990, PDF has solved one of the problems that helped document to look exactly the same everywhere, including text formatting and images, regardless of application software, hardware, and operating systems. The Portable Document Format or PDF has been one of the popular document formats out there.
