PDF/A document archiving API

Convert and archive your file formats into ISO-compliant PDF/A files that pass the veraPDF validator and the Adobe Acrobat Preflight tool. Our archiving API supports all common PDF/A substandards, including PDF/A-1 to PDF/A-4.




Frequently asked questions

What is PDF/A, and why use it for document archiving?

PDF/A is the ISO 19005 standard for long-term document preservation. It restricts features such as external font references, encryption, and embedded scripts so an archived file renders the same way years later. Nutrient’s document archiving API converts files to PDF/A and validates existing ones through the DWS Processor API.

Which PDF/A conformance levels does the API support?

The PDF/A conversion API supports PDF/A-1a, PDF/A-1b, PDF/A-2a, PDF/A-2b, PDF/A-2u, PDF/A-3a, PDF/A-3b, PDF/A-3u, and PDF/A-4. Choose the level your archive or compliance policy requires and pass it as a conversion option.

Which file formats can I convert to PDF/A?

You can convert PDFs, Microsoft Office documents, and images to PDF/A in a single request. See the getting started guide for API key setup and a first conversion.

How does PDF/A validation work?

The PDF/A validation API checks a file against the PDF/A specification and reports whether it conforms, so you can verify documents before they enter an archive. Files produced by the conversion API are built to pass the industry-standard veraPDF validator.

How is the document archiving API priced?

PDF/A conversion and validation are actions in the DWS Processor API and use credit-based pricing. You can start free with 50 credits per month; see Processor API pricing for production volumes.

Can I get help with a high-volume archiving workflow?

Yes. If you’re archiving large document volumes or need help mapping compliance requirements to PDF/A levels, contact Sales to talk through licensing and deployment options.
