Introduction High Efficiency Image File Format (HEIF) is a file format for individual images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is defined by MPEG-H Part 12. In June 2017, Apple announced support for HEIF in macOS High Sierra and iOS 11. 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.
Technical details The HEIF specification also defines the means of storing High Efficiency Video Codec (HEVC)-encoded intra images and HEVC-encoded image sequences in which inter prediction is applied in a constrained manner. The PDF combines three technologies: A subset of the PostScript page description programming language, for generating the layout and graphics. A font-embedding/replacement system to allow fonts to travel with the documents. A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate.
Associated programs iOS Adobe Acrobat, Adobe InDesign, Adobe FrameMaker, Adobe Illustrator, Adobe Photoshop, Google Docs, LibreOffice, Microsoft Office, Foxit Reader, Ghostscript.
