Convert PDFX to PDFA

Understanding PDFX and PDFA file formats

PDFX (PDF/X) is a subset of the PDF standard designed specifically for the graphic arts and printing industry. It ensures that files are print-ready by embedding all necessary fonts, images, and color profiles, and by restricting certain features that could cause printing issues.

PDFA (PDF/A) is an ISO-standardized version of PDF specialized for digital archiving and long-term preservation. It prohibits features unsuitable for archiving, such as encryption and external content references, ensuring that documents can be reproduced exactly the same way in the future.
