PDF, portable document format, based on PostScript and originally from Adobe, has many subsets.

As well as the 'full function' ISO 32000-1:2008 (or PDF 1.7), there are also PDF/X, PDF/A, PDF/E, PDF/VT and PDF/UA, all of which are ISO specifications.

PDF profiles (formalized subsets) include the following:

  • PDF/A (optimized for preservation)
    • PDF/A-1 (ISO 19005-1:2005)
    • PDF/A-2 (ISO 19005-2:2011)
    • PDF/A-3 (ISO 19005-3:2012) (extends PDF/A-2 by allowing embedded files of any type)
  • PDF/E (ISO 24517-1:2008) (for engineering workflows)
  • PDF/UA (ISO 14289-1) (making documents accessible through assistive technologies)
  • PDF/VT (ISO 16612-2) (support for variable document printing)
  • PDF/X (support for prepress graphics exchange)
    • PDF/X-1 (ISO 15930-1:2001)
    • PDF/X-1a (ISO 15930-4:2003)
    • PDF/X-2 (ISO 15930-5:2003)
    • PDF/X-3 (ISO 15930-6:2003)
