Description:

PDF/A differs from PDF by prohibiting features unsuitable for long-term archiving, such as font linking (as opposed to font embedding) and encryption. Note that "PDF/A" is actually a collection of formats:

  • PDF/A-1: "Part 1: Use of PDF 1.4" (2005-09-28)
  • PDF/A-2: "Part 2: Use of ISO 32000-1" (2011-06-20)
  • PDF/A-3: "Part 3: Use of ISO 32000-1 with support for embedded files" (2012-10-15)
  • PDF/A-4: "Part 4: Use of ISO 32000-2" (2020-11)

Centres should note that Part 1 references an obsolete version of PDF, while parts 2 and 3 reference the fully open PDF 1.7.

VeraPDF is an open-source validator for PDF/A formats.
