How to convert PDF to PDF/A.
PDF/A is an ISO-standardized version of the Portable Document Format (PDF) specialized for use in archiving and long-term preservation of electronic documents. PDF/A differs from PDF by prohibiting features ill-suited to long-term archiving, such as font linking (as opposed to font embedding) and encryption. The ISO requirements for PDF/A file viewers include color management guidelines, support for embedded fonts, and a user interface for reading embedded annotations.
