QuotePDF has become a de facto global standard for more secure and dependable information exchange since Adobe published the complete PDF specification in 1993. Both government and private industry have come to rely on PDF for the volumes of electronic records that need to be more securely and reliably shared, managed, and in some cases preserved for generations. Since 1995 Adobe has participated in various working groups that develop technical specifications for publication by ISO and worked within the ISO process to deliver specialized subsets of PDF as standards for specific industries and functions. Today, PDF for Archive (PDF/A) and PDF for Exchange (PDF/X) are ISO standards, and PDF for Engineering (PDF/E) and PDF for Universal Access (PDF/UA) are proposed standards. Additionally, PDF for Healthcare (PDF/H) is an AIIM proposed Best Practice Guide. AIIM serves as the administrator for PDF/A, PDF/E, PDF/UA and PDF/H.
