Frequently asked questions

What is PDF/A and the ISO 19005 standard?

PDF/A is a restricted form of PDF defined by ISO 19005 for long-term preservation. It requires documents to be self-contained — embedded fonts, defined colour, and no features that depend on external files — so they render identically far into the future.

What is the difference between PDF/A-1, PDF/A-2 and PDF/A-3?

PDF/A-1 (ISO 19005-1) is the strictest and oldest; PDF/A-2 adds JPEG2000, transparency and layers; PDF/A-3 also allows embedding arbitrary files (for example a source spreadsheet). Most archives accept PDF/A-1b or PDF/A-2b.

Why is this browser tool not certified PDF/A?

Certified PDF/A needs embedded font subsets, an ICC output intent and XMP metadata written exactly to spec, which a browser cannot reliably guarantee. This tool writes PDF/A-style markers as a best-effort approximation and may not pass strict preflight.

How do I validate PDF/A compliance?

Run the file through veraPDF (the open-source PDF/A validator) or Adobe Acrobat Pro’s Preflight. They report the exact conformance level and any violations to fix.

Who requires PDF/A for submissions?

National archives, many courts and e-filing systems, academic repositories and some government tenders mandate PDF/A. Always check the required conformance level (for example PDF/A-1b vs PDF/A-2b) before submitting.
