PDF to PDF/A

What is PDF to PDF/A Conversion?

PDF to PDF/A conversion is the process of converting standard PDF documents to the PDF/A format compliant with ISO 19005 for long-term archiving. It is used for legal archiving, government compliance, and preserving digital documents for decades. PdfMetric's PDF to PDF/A conversion tool applies font embedding, color space normalization, and metadata standardization to support PDF/A-1b, PDF/A-2b, and PDF/A-3b profiles. Government agencies, lawyers, accountants, and archivists perform this conversion regularly.

Standard PDFs may contain external font references, RGB/CMYK mixing, and uncompressed objects. Over time, as software and operating systems change, these documents can become unreadable. PDF/A mandates that all fonts be embedded, color spaces be fixed, and metadata be standardized. This ensures the document can be stored for decades with the same appearance and content. The ISO 19005 standard technically defines these requirements.

PDF/A-1b is the basic compliance level; visual appearance is preserved. PDF/A-2b supports advanced features such as transparency and JPEG2000. PDF/A-3b allows embedded files (e.g., XML, Excel), enabling hybrid archive documents. For government compliance, many government agencies require the PDF/A format. Legal archiving is critical for court documents, tax records, and contracts.

When Should You Use It?

• Legal archiving: Convert contracts, rulings, and official documents to PDF/A for long-term storage.
• Government requirements: Make documents compliant for submission to government archives.
• Accounting and tax: Convert accounting documents to archive format for tax audits.
• Corporate document management: Ensure long-term readability in company archives.
