But conversion to PDF/A is just not good enough.
Just converting your files to PDF/A alone is not good enough. Content will be lost: think of macros, scripts or formulas in Microsoft Excel. Also the layout, styles and form do often not quite match the original.
You must be able to prove that the information is authentic and reliable.
And that wont be possible with just a conversion to PDF/A.
You are familiar with the blue header in a PDF that says: ” This file claims compliance with the PDF/A standard and has been opened as read-only to prevent modification”.
Read-only? Safe? No, absolutely not!
A PDF/A file can be modified and tampered with very easy. No special hacker tools required, just using standard Adobe Acrobat:
–> Open the file and select Enable Editing. Then make the changes you want as Save As a PDF/A again.
When someone now opens the PDF again, it shows the PDF/A header and nothing seems wrong.
