Frequently asked questions
What is the difference between PDF/A-1b, PDF/A-2b, and PDF/A-3b?+
PDF/A-1b (ISO 19005-1) is the original 2005 standard. PDF/A-2b (ISO 19005-2) adds transparency, JPEG 2000, and embedded files. PDF/A-3b (ISO 19005-3) allows attaching arbitrary file types as embedded files.
Which veraPDF profile should I use for validation?+
Select the profile matching your target conformance level: 'pdfa-1b', 'pdfa-2b', or 'pdfa-3b' in veraPDF's validation wizard.
Can I convert a digitally signed PDF to PDF/A?+
Conversion re-saves the PDF, which invalidates existing digital signatures. Apply the digital signature after converting to PDF/A.
