What is Convert PDF to PDF/A?
PDF/A is an ISO-standardized subset of PDF designed for long-term archival. Unlike a regular PDF, a PDF/A file embeds all fonts inside the document, disallows external dependencies (links, embedded scripts, encrypted content), and includes explicit XMP metadata identifying it as PDF/A-compliant. Government archives, legal repositories, healthcare records systems, and academic libraries often require PDF/A specifically because it's guaranteed to render the same way decades from now. PDF Zone's PDF to PDF/A tool performs best-effort conversion in your browser: it embeds fonts where possible, strips JavaScript and encryption, removes external references, and adds the XMP metadata identifying the file as PDF/A-2b-compatible. For mission-critical archival where formal certification is required, you'll still want to validate the output with a tool like veraPDF — but for everyday compliance and long-term storage, this conversion handles the practical work.

Frequently asked questions
PDF/A is an ISO-standardized version of PDF (ISO 19005) designed for long-term archival. It guarantees that a document will look the same 50 years from now as it does today by embedding all fonts inside the file and forbidding features that depend on external resources — JavaScript, encryption, dynamic linked content, audio, video. Many government agencies, legal archives, and compliance frameworks require PDF/A specifically for this reason.
A regular PDF can reference fonts installed on your computer, contain JavaScript, link to external resources, and use encryption. A PDF/A version of the same document must embed every font, must contain no scripts, must have no external dependencies, and must not be encrypted. Visually they look identical, but a PDF/A is guaranteed to render the same way decades from now regardless of what fonts are installed or what tools are available. That guarantee is why archives and courts require it.
This is a best-effort browser-based conversion. It embeds fonts where the source file permits, strips disallowed features, and adds the PDF/A XMP metadata. For most archival and compliance use cases it's sufficient. For mission-critical certified archival — government records, legal evidence preservation — you should validate the output with veraPDF (an open-source PDF/A validator) and, if required, run the file through a certified PDF/A processor like Adobe Acrobat Pro.
PDF/A-2b — the most widely supported variant. PDF/A-1 is the original, most restrictive variant (no transparency, no JPEG 2000); PDF/A-2 added support for those and is the standard choice today; PDF/A-3 allows embedded attachments and is mostly used for e-invoicing. For general archival use, PDF/A-2b is the right pick.
No. The conversion runs entirely in your browser. The PDF never gets uploaded to any server — important when the document is sensitive (financial, legal, medical) and you only want PDF/A compliance for safekeeping, not to expose it to a third party.
