Frequently Asked Questions

Which PDF/A version should I choose? For most legal and archival needs, PDF/A-2b is the modern standard as it supports transparency and layers.

Is PDF/A the same as a regular PDF? No. Standard PDFs can contain JavaScript or external fonts that might break over time. PDF/A ensures everything needed to view the file is "static" and embedded.

Does PDF/A reduce file size? Often it increases it slightly because it embeds all fonts and metadata to ensure self-containment.
