Pro server tool. Uses Ghostscript PDF/A-2 conversion for archive-friendly output.

How to use PDF to PDF/A Converter

  1. Upload the PDF you need to archive or submit for compliance.
  2. The tool converts it to PDF/A, the ISO standard for long-term document archiving (fonts embedded, no external dependencies, no JavaScript or encryption).
  3. Download the PDF/A file — this is what courts, government agencies, and archives typically require.

Limitations

  • PDF/A strips interactive elements like JavaScript and encryption by design — that's the point of the standard, not a bug.
  • Very old or malformed source PDFs may not convert cleanly; try re-saving the original first if conversion fails.

Frequently asked questions

Why would I need PDF/A instead of a regular PDF?

PDF/A guarantees the file will render identically decades from now — fonts are embedded, there's no dependency on external resources. Many courts, government filing systems, and institutional archives require it specifically.
