Common Questions

: PDF/A is an ISO standard (ISO 19005) for PDF files optimised for long-term archiving. It restricts certain PDF features that might prevent reliable rendering in the future.
: No. PDF/A does not permit encryption. Remove the password first using Remove Password, then convert to PDF/A.
