Redax has the ability to redact areas that are marked up using Acrobat’s highlight, strikeout and underline tool. All other annotations can not be redacted using Redax. Redax offers a Remove All Annotations menu option. It Deletes All Annotations from a PDF document, all Redax boxes, exemption codes and any other annotations, such as Acrobat notes or those added by other plug-ins. Redax 4.6 and higher can redact Acrobat 8, and all subsequent versions, including XI redaction markup.
