Image files that employ JPEG compression are commonly called "JPEG files", and are stored in variants of the JIF image format. 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. The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.
JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. Application/pdf, application/x-pdf, application/x-bzpdf, application/x-gzpdf
