The status window displays the verification result.


To reveal PDF/A documents

  2. You can:
    1. Right-click or click on the Edit menu and select Reveal PDF/A documents.
    2. Click on the icon from the My computer

The icon appears beside the PDF/A documents among those selected.

Note that no compliance validation is performed with the reveal function; it simply looks up the PDF/A claim metadata in the document.


To add an attachment to a PDF/A

  1. From the document pane, click on the “Attachments” tab

  1. You can then select any file you want to add.

A convenient option of the PDF document format is the ability to attach files of any format, much like email attachments.  This option does not limit the properties of the PDF document. In particular, the PDF document with attachments can :

  • Be converted to PDF/A format (PDF/A-3b format allows attachments. See: Questions/Answers : The PDF/A Format)
  • Be digitally signed, which guarantees the integrity of the document and the attached files, since the digital signature covers the PDF document and its attachments.

Thus, if a document cannot be converted to PDF/A format or its format is not practical for digital signature, you can, with ConsignO Desktop, attach it to a PDF document that can be converted to PDF/A-3b format and digitally signed to guarantee the integrity of the attachments.
