Type of format Image Container Format Document format
Introduction As HEIC is a container format, it can contain still images and image sequences (where a file contains more than one single image) that are coded in different formats. Currently, these include HEVC and H.264/MPEG-4 AVC (and JPEG for thumbnail/secondary images), though other coding formats may be added in the future. The main filename extension is .heic (for HEVC codec). 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 In Apple's implementation, for single images they have chosen the latter .heic filename extension (.heics for image sequence files) as the only one they will produce for photos, which indicates clearly that it went through HEVC encoding. 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.
