Understanding the PDF/A Format

Roy knows that in Word he can save a file to PDF format. He recently was informed at a Federal Court that he had to save his documents in "PDF-a" format. Roy hasn't heard of the "PDF-a" format prior to this encounter, so he wonders if Word can save documents in "PDF-a" format and how the format is different from the regular PDF format.

Most everyone is familiar with the standard PDF file format. The PDF-a format (sometimes noted as PDF-A or, more commonly, as PDF/A) is a variation that is optimized for long-term storage of the documents. Essentially, the format has everything embedded in it, rather than allowing internal links to external information. In addition, some objects aren't even allowed in a PDF/A document at all. They cannot contain the following:

  • Audio or video content
  • JavaScript or executable files (or links to external executable files)
  • Encryption of any type
  • Embedded files, such as other PDF files
  • Transparent objects (graphics) and layers

The purpose to these limitations is to make sure that the PDF/A file contains everything within itself that is necessary to fully display the file contents at any future date, regardless of how the technology may change. Further information about the PDF/A standard can be found in a variety of places, including Wikipedia:

https://en.wikipedia.org/wiki/PDF/A

The definitive place for information on PDF/A can be found at the PDF/A Competence Center:

By default, Word saves documents in regular PDF format. If you want to force Word to save in PDF/A format, you can follow these steps:

  1. Press F12 to display the Save As dialog box.
  2. Click on the down arrow next to the Save As Type drop-down list and choose PDF as your file type.
  3. Click on the Options button. Word displays the Options dialog box.
  4. Make sure the PDF/A Compliant (ISO 19005-1) check box is selected.
  5. Click OK to close the Options dialog box.
  6. Enter a name for the PDF/A file in the File Name box.
  7. Click Save.

I am working with MS Office 2019, which does not list PDF/A as an option.
Is there something one can do to make it available?

According to the wikipedia article you cite, transparent objects and layers are allowed in PDF/A-2.
