Convert PDF to PDF/A — Archive-Ready in One Click

PDF/A is the ISO-standardized version of PDF designed specifically for long-term preservation of digital documents. Government agencies, law firms, hospitals, banks and archives all require PDF/A for any document that must remain openable and visually identical decades from now. Our PDF to PDF/A converter rewrites your PDF with PDF/A-1b metadata, embedded XMP, and a structure tuned for archival viewers — all in one click.

The conversion process re-serializes every page losslessly into a fresh document, then attaches an XMP metadata stream declaring PDF/A-1b conformance along with title, producer, creation and modification dates. The output is saved with object streams disabled — exactly how compliant PDF/A viewers expect to parse the file — so it opens cleanly in Adobe Acrobat, Foxit, and document management systems that enforce archival standards.

This tool is ideal for legal teams preparing case files, HR departments archiving signed contracts, finance teams storing audit-ready statements, and anyone who needs to convert everyday PDFs into a stable, future-proof format. Files are processed in memory and discarded immediately — your documents never touch persistent storage.

Important: this tool produces a PDF/A-1b–flagged document that works in the overwhelming majority of archival workflows. If your organization runs a strict PDF/A validator (such as veraPDF) and your source PDF contains non-embedded fonts, encryption, or transparency, a full PDF/A re-render with Ghostscript may still be required as a final step.
