Convert PDF to PDF/A for Archiving

Last updated: March 1, 2026

PDF/A is the ISO standard for long-term document archiving. Unlike regular PDFs, PDF/A files embed all fonts, disable external references, and ensure the document will render identically decades from now. Government agencies, legal firms, and regulated industries require PDF/A for compliance. OneClickPDF converts standard PDFs to PDF/A format entirely in your browser.

Technical Details

PDF/A is defined by ISO 19005. The key requirements are: all fonts must be embedded, no external content references (JavaScript, audio, video), color spaces must be device-independent, and metadata must use XMP format. OneClickPDF handles these requirements automatically during conversion. The output targets PDF/A-1b compliance, which focuses on visual preservation.

Frequently Asked Questions

What is PDF/A?
PDF/A is an ISO-standardized version of PDF designed for long-term digital preservation. It ensures documents can be reproduced exactly the same way in the future by embedding all necessary resources (fonts, color profiles) and prohibiting features that require external dependencies.
Will the document look different after conversion?
No. PDF/A conversion preserves the visual appearance. The changes are internal — fonts are embedded, external references are removed, and metadata is standardized.
Which PDF/A version does it produce?
The converter targets PDF/A-1b, which focuses on visual preservation and is the most widely accepted version for archival and compliance purposes.
Is my file uploaded to a server?
No. The entire conversion runs in your browser. Your PDF never leaves your device.
