Why PDF/A?

PDF/A is conceived for users who want to be sure that their documents contracts,

invoices or technical documentation are legible and useable even after 10, 50 or

100 years.

Only the PDF/A standard can guarantee that users will be able to view exactly the

same content as when their documents were created.

PDF/A

ISO Standard for Long-Term Archiving

ISO 19005-1 defines “a file format based on PDF, known as PDF/A, which provides a mechanism for representing electronic documents in a manner that preserves their visual appearance over time, independent of the tools and systems used for creating, storing or rending the files.” (from ISO 19005-1). The Standard does not define an archiving strategy or the goals of an archiving system. It identifies a “profile” for electronic documents that ensures the documents can be reproduced in years to come.

A key element to this reproducibility is the requirement for PDF/A documents to be 100 % self-contained. All of the information necessary for displaying the document in the same manner every time is embedded in the file. This includes all visible content like text, raster images, vector graphics, fonts, color information and much more. A PDF/A document however is not permitted to be reliant on any information from direct or indirect external sources, for example links to external image files or font that are not embedded.

Why do you need PDF/A?

The PDF/A standard for long-term archiving was adopted by ISO (International Standards Organization) in autumn 2005. The PDF/A standard aims to enable the creation of PDF documents, the visual appearance of which will remain the same over centuries. It is conceived for users who want to be sure that their documents contracts, invoices or technical documentation are legible and useable even after 10, 50 or 100 years.

That the inventor of the PDF format, Adobe Systems, has revealed its format implies for users and developers, an assurance that programs will be available for generation and display of PDFs even after decades. However, only the PDF/A standard can guarantee that users will be able to view exactly the same content as when their documents were created.

How does PDF/A differ from normal PDF?

Based on PDF Version 1.4 (corresponding to Acrobat 5), the PDF/A standard includes a number of minimum requirements and restrictions, ensuring that PDF documents are always reproduced in a unique manner.
