Can adobe acrobat dc convert word perfect document to a pdf that I can sign?

With your Word Perfect file open, go to File...Choose "Publish To", then select PDF.

Acrobat does not have any direct conversions of WordPerfect documents to PDF. You do have three options to create PDF files from WordPerfect files.

(1)     Open your WordPerfect file in WordPerfect and use its native PDF creation to create the PDF file and then do the rest of the workflow in Acrobat.

(2)     Open your WordPerfect file in WordPerfect and print to the Adobe PDF PostScript printer driver instance which will create PostScript and convert same to PDF, opening the resultant file in Acrobat.

(3)     Open your WordPerfect file in WordPerfect and save it as a Word or an RTF file which then can be treated by Acrobat as a native Word file.
