The PDF Standard Actions convert documents to/from alternative PDF formats:
Convert to PDF/A makes documents compliant with the PDF/A format, which is ideal for long-term archiving.
Convert to PDF/X makes documents compliant with the PDF/X standard, which is used to exchange printing data.
Discard Special PDF-Standard discards special PDF information from documents such as PDF/X, PDF/A and PDF/E information.
