||The Portable Document Format (PDF) is a file format used to present documents in a manner
independent of application software, hardware, and operating systems. Each PDF file
encapsulates a complete description of a fixed-layout flat document, including the text,
fonts, graphics, and other information needed to display it.
||JPEG is a commonly used method of lossy compression for digital images, particularly for
those images produced by digital photography. The degree of compression can be adjusted,
allowing a selectable tradeoff between storage size and image quality. JPEG typically
achieves 10:1 compression with little perceptible loss in image quality.
