Understanding PDF/A Conformance Standards
PDF/A-1b (ISO 19005-1)
The classic standard for visual preservation. Guarantees that the document displays and prints identically on any computer over decades without external dependencies.
PDF/A-2b (ISO 19005-2)
The recommended modern baseline. Adds support for JPEG 2000 compression, transparency layers, and embedded OpenType fonts while preserving archival integrity.
PDF/A-3b (ISO 19005-3)
Advanced business archive standard. Allows embedding structured raw XML files (such as ZUGFeRD / Factur-X electronic invoices) directly inside the PDF/A file.
Frequently Asked Questions
Why do legal courts and banks require PDF/A?
Standard PDFs can reference external fonts or unstandardized color profiles that might render incorrectly years from now. PDF/A strictly embeds all font definitions, colors, and metadata so the document will remain legally authentic and visually identical for decades.
