Convert PDF to PDF/A (Archival Format) Online — Free

PDF/A is an ISO-standardized subset of PDF designed for long-term digital preservation of electronic documents. Unlike standard PDFs that may rely on external resources (fonts, color profiles, multimedia), PDF/A files are completely self-contained — all fonts are embedded, color spaces are device-independent, and interactive elements are removed. This makes PDF/A the required format for government archives, legal document retention, healthcare records, and financial regulatory submissions.

Our converter uses Ghostscript to transform standard PDFs into fully compliant PDF/A-2b documents, embedding all fonts, converting color spaces, and stripping non-archival elements while preserving the visual appearance of your document. The process injects a compliant XMP metadata stream and validates the output against PDF/A specifications.

Organizations across industries rely on PDF/A for regulatory compliance: law firms archive case files in PDF/A for court submission requirements, financial institutions convert quarterly reports for SEC and FINRA retention mandates, healthcare providers store patient records in PDF/A for HIPAA-compliant long-term preservation, and universities require PDF/A for institutional repository deposits and thesis submissions.

The PDF/A-2b standard (ISO 19005-2) is the most widely accepted version, supporting JPEG2000 compression, transparency layers, and embedded file attachments while maintaining backward compatibility. Our converter handles all common PDF features including embedded images, vector graphics, custom fonts, and form field content.
