PDF/A (PDF Archive)

PDF/A is a specialized version of the PDF format designed for long-term digital preservation of electronic documents. It ensures that files remain unchangeable and viewable the same way in the future by embedding all necessary information—like fonts and colors—within the file itself. Unlike regular PDFs, PDF/A prohibits features like external links or multimedia that could affect how the document appears over time. This makes PDF/A ideal for libraries, archives, and organizations needing reliable, unalterable records for legal, historical, or regulatory purposes.
