What is PDF/A format?
PDF/A is an ISO-standardized version of PDF designed for long-term archiving. It ensures documents can be reproduced exactly the same way in the future, regardless of software. All fonts are embedded, colors are device-independent, and encryption is prohibited.
Which PDF/A version should I choose?
PDF/A-1B for legal/government documents (most compatible). PDF/A-2B for modern docs with transparency/layers. PDF/A-3B when you need to embed other files inside the PDF.
Why convert to PDF/A?
Many organizations, courts, and government agencies require PDF/A for document submission. It ensures your document will be viewable and printable exactly as intended for decades to come.
