Frequently asked questions

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

PDF/A-1b is the strictest standard, great for legal filing. PDF/A-2b adds support for JPEG 2000 compression and embedded files.

Why do I need PDF/A for archives?

PDF/A embeds all fonts and color data so the document looks identical in any viewer, even decades later.

Does conversion change the visual appearance?

Rarely. Transparency effects may be flattened and unsupported color spaces converted, but text and layout remain the same.

Is it accepted for legal and government filing?

PDF/A-1b is widely accepted by courts, tax authorities, and government agencies worldwide.

Can I convert a scanned PDF to PDF/A?

Yes. Scanned PDFs without text layers can still be converted to PDF/A. Add OCR first if you need searchable text.
