Convert PDF to PDF/A online free. Create ISO-compliant archival PDFs for legal, government, and long-term document storage. No signup.
PDF/A is the ISO-standardized version of PDF built specifically for long-term archiving — it embeds all fonts, disables external dependencies, and avoids encryption or JavaScript, so a document opens identically whether it's read today or in 20 years. Many courts, government agencies, and institutional archives require PDF/A specifically, not standard PDF, for permanent records. PDF HUB 24 converts any regular PDF into ISO 19005-compliant PDF/A in seconds.
When You Need PDF/A Instead of Regular PDF
PDF/A conversion matters most for documents meant to last, or where a specific standard is required:
- Court filings and legal records requiring long-term archival compliance
- Government submissions that specify PDF/A as the accepted format
- Corporate records retention for financial, medical, or HR documents
- Academic theses and dissertations submitted to institutional repositories
- Digitized historical documents intended for permanent digital preservation
- Any document where you need certainty it will render identically decades from now

Frequently Asked Questions
What's the difference between PDF and PDF/A?
PDF/A is a restricted, ISO-standardized subset of PDF designed for long-term archiving — it requires embedded fonts, disallows encryption and JavaScript, and guarantees the document will render the same way indefinitely. Regular PDF has no such guarantees.
Will my document look different after converting to PDF/A?
Visually, no — text, layout, and images remain the same. What changes is internal structure: fonts get embedded, and any non-compliant interactive elements are removed.
Is PDF/A required for all government submissions?
It depends on the specific agency or court — many require PDF/A for permanent records, but not all. Check the submission guidelines for your specific filing.
