### Archival (PDF/A, ISO 19005)

Converts to the PDF/A-1b, PDF/A-2b, or PDF/A-3b format. All fonts used in the source document are embedded in the generated PDF file, and PDF tags are written. The primary purpose is to create an electronic document whose appearance is device and application independent, making it suitable for long term preservation.
