Free PDF to PDF/A Converter - Create Archive-Quality PDFs

Need to preserve documents for long-term archival or meet compliance requirements? PDF/A is the ISO-standardized format designed specifically for electronic document preservation and archiving. Convert your regular PDFs to PDF/A format to ensure documents remain viewable and accessible for decades to come, meeting legal, regulatory, and institutional archiving standards.

What Is PDF/A?

PDF/A is an ISO-standardized version of PDF specifically designed for long-term archiving and preservation of electronic documents. Unlike regular PDFs, PDF/A files are self-contained with all fonts, images, and information embedded, ensuring documents look identical decades from now regardless of software or hardware changes. It's widely required for legal documents, government records, academic archives, and regulatory compliance.

Why Convert to PDF/A?

  • Long-Term Preservation: Ensure documents remain viewable and unchanged for decades, meeting archival standards for permanence.
  • Legal Compliance: Meet legal and regulatory requirements for document archiving in government, healthcare, finance, and legal sectors.
  • Self-Contained Documents: All fonts, images, and resources are embedded, eliminating dependencies on external files or fonts.
  • Guaranteed Consistency: Documents appear identical on any device or software, now and in the future.
  • Regulatory Requirements: Comply with regulations like HIPAA, Sarbanes-Oxley, GDPR, and other standards requiring archival formats.
  • Institutional Archives: Perfect for libraries, museums, universities, and organizations maintaining permanent document collections.
