PDF Competence Center

The members of the TWG come from a variety of backgrounds, but are primarily developers working for vendors creating products that create or consume PDF files. Some members are also actively involved in the ISO PDF committees which set the international standards that define PDF technology. Together, we have a wide and deep experience of PDF, both theoretical and practical. We are therefore ideally placed to discuss any ambiguities in the standard, to jointly develop best practices, and to share advice, e.g. to ensure that PDF files are appropriately prepared for their target use cases and audiences.

The PDF Competence Center’s Technical Working Group is dedicated to supporting developers with publications and other resources to assist in creating software to comply with ISO 32000, the International Standard for the Portable Document Format (PDF).

Why PDF?

  • Self-contained, totally portable across platforms
  • Tremendous flexibility and power in representing documents and forms
  • Easy to create using hundreds or thousands of independent implementations
  • May be secured for distribution and protection
  • May be authenticated with digital signatures
  • May include semantics to assist in content reuse and accessibility
  • The non-proprietary, democratically-managed, globally-accepted de facto standard for electronic documents

How to get ISO 32000

Adobe Systems published PDF 1.0 – 1.7, and provided these early versions of the PDF specification at no cost.

The first ISO standardized specification for PDF, ISO 32000-1 (PDF 1.7), is available for free by special arrangement between ISO and Adobe Systems. Note that Adobe’s Extension Levels are not part of the ISO standard.

For those who prefer to pay, ISO 32000-1 may be purchased online from ISO’s website or your country’s own standards body.

ISO 32000-2:2017, the current version of the PDF specification is not freely downloadable: a purchase is required.
