Is there a reason you cannot do this inside wordperfect? Wordperfect can view PDF files, and save to its own native format. This works fine for single use documents, I understand the need for a program with a batch of PDF's to convert.
To do it in wodpefect:
1: Opn wordperfect and click "file" and "open PDF" navigate to the desired file and click "open
2. Make any necessary changes and click "file" and choose "save as" from the drop down menu. Set file type to (Wordperfect .wpd) name and save the file.
As for the programs:
An all-in-one converter program like this one will allow you to batch convert between all sorts of different formats.
*wordperfect, apologies for the fast clicking! lol
