PDF/A: The Archive Format for Documents

PDF/A is a PDF variant designed for long-term archiving, defined in ISO 19005. Preserves legibility and machine-readability for decades — a building block for GoBD-compliant archives.

How it differs from regular PDF

  • All fonts embedded
  • No external references
  • No JavaScript, no audio/video
  • No encryption, no DRM
  • Defined colour space

The variants

  • PDF/A-1 — PDF 1.4, most restrictive
  • PDF/A-2 — adds JPEG 2000 and transparency
  • PDF/A-3 — allows file attachments (ZUGFeRD, Factur-X)
