Create a PDF/A file

Nitro Pro 7 enables you to create PDF/A compliant files. This means you can create PDF/A compliant files by simply printing to Nitro PDF Creator, as well as using the Office add-ins or Scan to PDF functionality.

About PDF/A

Intended to support long-term archiving of electronic documents, PDF/A is a archival standard approved by ISO. Compliance with the standard guarantees that PDF/A documents can be viewed and reproduced in exactly the same way for years to come, regardless of future changes to the PDF format.

In order to achieve this, all PDF/A documents are required to be 100% self-contained. This means that all of the information necessary for displaying the document must be embedded in the file, including all content (text, images and graphics), as well as fonts and color information.

PDF/A prohibits certain PDF features that prevent long-term archiving of the PDF file, such as hyperlinks to external sources, embedded audio and video content, and inclusion of Java Scripts and executable files. Additionally, PDF/A compliant documents cannot be encrypted, while the use of standards-based metadata and device-independent colorspaces are required.

PDF/A-1a and PDF/A-1b

The PDF/A standard includes two levels of compliance for PDF files: PDF/A-1a and PDF/A-1b. PDF/A-1b conformance ensures the document’s visual appearance will be reliably reproduced over the long term, while PDF/A-1a inserts an additional requirement that the document structure be included, to guarantee content re-purposing (for example, in displaying PDFs on portable devices such as PDAs) as well as to make certain the document will be accessible to impaired users.

Nitro Pro 7 can create PDF files which are compliant with the PDF/A-1b standard.
