Our PDF to PDF/A converter is designed to help you prepare PDF documents for long-term digital preservation. PDF/A is an archival-oriented version of PDF that is designed to make documents more reliable for future access, storage, and reproduction.
Unlike a normal PDF file, a PDF/A document is intended to contain the resources and information needed to reproduce its visual appearance independently of external resources. This makes PDF/A particularly useful for organizations, businesses, educational institutions, government records, legal archives, invoices, reports, and other documents that may need to remain accessible for many years.
What is PDF/A?
PDF/A is an ISO-standardized family of PDF specifications created for long-term electronic document preservation. Different PDF/A versions and conformance levels provide different capabilities depending on the type of document being archived.
For example, PDF/A-1 is based on an earlier PDF specification, while PDF/A-2 provides additional modern PDF capabilities. PDF/A-3 also allows certain files to be associated with the archival document.
Why Convert PDF to PDF/A?

PDF/A-1b vs PDF/A-2b
PDF/A-1b focuses on preserving the visual appearance of a document and is widely used for archival workflows. PDF/A-2b is based on a newer PDF specification and supports additional features that are not available in PDF/A-1.
If you are unsure which format to select, PDF/A-2b is often a practical choice for modern archival workflows. However, always follow the technical requirements of the organization or archive receiving your documents.

Is PDF/A Different From Normal PDF?
Yes. A normal PDF is designed primarily for document viewing, sharing, and printing. PDF/A adds restrictions and requirements intended to make documents more suitable for long-term preservation.
PDF/A workflows can require appropriate metadata, color information, embedded resources, and other document properties. PDF/A also restricts features that can make long-term reproduction dependent on external or changing resources.
Are My Files Uploaded to a Server?
This browser-based tool processes the selected document directly in your web browser whenever the required PDF processing libraries are available. Your PDF is not intentionally sent to a separate conversion server by the tool code below.
Because PDF files can contain confidential information, you should still review your organization's security and privacy requirements before processing sensitive documents online.
Important PDF/A Compatibility Information
A PDF/A conversion is more than simply changing the file extension. PDF/A conformance can depend on the internal structure and content of the source document. Some PDFs may contain unsupported features, unembedded fonts, encryption, external dependencies, or other elements that require additional processing.
For documents that must satisfy a strict archival requirement, the resulting file should be checked with a dedicated PDF/A validation tool after conversion.
