Archival PDF/A format
Convert PDFs to archival PDF/A format
Convert standard PDFs to PDF/A — the ISO-standardized archival format designed for long-term preservation. PDF/A ensures your documents remain readable and visually identical decades from now by embedding all fonts, banning external dependencies, and enforcing strict structure rules. Also includes a validation mode to check if existing PDFs already comply with PDF/A standards. Essential for legal archives, government submissions, and institutional document storage.
Why this is in the app
PDF/A conversion requires precise control over document structure and font embedding — features that require the full processing pipeline.

What is the difference between PDF and PDF/A?
PDF/A is a stricter version of PDF designed for archiving. It requires fonts to be embedded, forbids JavaScript, external file references, and encryption. This guarantees the document looks the same when opened decades later.
Which PDF/A version should I use?
PDF/A-1b is widely accepted. PDF/A-2 and PDF/A-3 offer additional features like layer support and embedded files. Check with the institution requiring the format for their specific version preference.
