Frequently Asked Questions

What is PDF/A and why is it needed?

PDF/A is an ISO standard for archiving PDFs. It ensures the document is self-contained with all fonts, colours, and metadata embedded so it can be reproduced exactly the same decades later.

Does PDF/A look different from a regular PDF?

Visually identical. PDF/A simply has stricter rules about what can be embedded — no JavaScript, no external dependencies, fonts must be fully embedded.

Which PDF/A version should I use?

PDF/A-1b is the most widely accepted. PDF/A-2 and PDF/A-3 add support for newer features. Check the specific requirement of the government or legal body before converting.
