Characteristics

File extension .pdf
Internet media type application/pdf
Description: PDF, or Portable Document Format, is a popular file extension that was first introduced in 1993 by Adobe Systems. PDF appeared as a platform-independent solution which would allow users to view and share documents easily regardless of device types and operating systems. Another useful feature of this format is that it uses a fixed page layout.
Technical Details: A PDF file may contain a variety of content, including text blocks, graphic information, and interactive fields such as buttons, hyperlinks, bookmarks, etc. It also contains information about the fonts used in the document, and thus, PDF files always appear the same when documents are exchanged between users working on different computers.
Developed by ISO
Initial Release: 15 June 1993
