About this tool

PDF to PDF/A

Convert a PDF toward the PDF/A format used in document-archiving workflows. PDF/A places additional requirements on a document so it can be reproduced more consistently over time. If an organization requires a particular PDF/A profile or certified compliance, validate the output against those requirements before submission.
