PDF Archiving for Long-term Preservation
The PDF/A Standard
PDF/A is the ISO standard for long-term archiving of electronic documents. Unlike standard PDF, it guarantees the longevity of your documents.
Key requirements:
- Embedded fonts: All fonts must be embedded in the file
- Self-contained: No references to external content
- Standardized colors: Embedded color profiles
- Metadata: Document information embedded
Note: A PDF/A will often be larger than a standard PDF due to embedded fonts, but this is the price of longevity.
PDF/A Versions
PDF/A-1 (2005)
• PDF/A-1a: Full compliance, extractable text
• PDF/A-1b: Minimal compliance, visual display
PDF/A-2 (2011)
• OpenType support, JPEG2000
• Transparency and layers allowed
PDF/A-3 (2012)
• Allows embedding arbitrary files
• Ideal for archiving sources + rendering
PDF/A-4 (2020)
• Based on PDF 2.0
• Latest version of the standard
Practical Guide: Creating a PDF/A
From LaTeX
% LaTeX preamble
\usepackage[a-1b]{pdfx}
\usepackage{hyperref}
% Compilation
pdflatex document.tex
LaTeX with the pdfx package automatically generates compliant PDF/A files with embedded fonts.
From Word/LibreOffice
- 1. File → Export as PDF
- 2. Options → PDF/A-1b
- 3. ✓ Embed fonts
- 4. ✓ Include standard fonts
Always verify with a PDF/A validator as Word can produce non-compliant PDFs.
Best Archiving Practices
- • Always keep the source file (.tex, .docx) alongside the PDF/A
- • Use descriptive filenames with dates (2024-12-annual-report.pdf)
- • Store on multiple media (cloud + local disk + backup)
- • Document content with comprehensive metadata
- • Regularly test opening your archives
