How to Convert PDF to PDF/A Online for Free

What is PDF/A and Why Convert to It?

PDF/A is the ISO-certified archival standard for PDF documents. Unlike regular PDFs, a PDF/A file is completely self-contained — all fonts, color profiles, and resources are embedded inside the file. This guarantees the document will look exactly the same when opened 10, 20, or 50 years from now, regardless of what software is available.

Many organizations — courts, government agencies, healthcare systems, and financial institutions — require documents to be submitted in PDF/A format for long-term compliance and archival.

Which PDF/A Version to Choose?

PDF/A-1b

Most restrictive. No transparency. Maximum compatibility.

PDF/A-3b

Allows embedded attachments. For complex document packages.
