With WordPerfect Office X5, you can open PDF files, even scanned PDFs (which traditionally have to be retyped), and edit the contents just as you would any other document.
In other words, you want to be able to archive documents as PDF files that will be readable for years to come.
If you set an "open" password, the reader must know the password to view the contents. There are two levels of password protection: open and permission.
That's right-WordPerfect Office lets you open PDF files, edit them and save them back to any of the 60+ file formats WordPerfect supports, or publish to PDF for sharing. WordPerfect® Office is considered the world's first "PDF office suite" with built-in features to open, edit and publish PDF documents. Pretty Darn Fabulous!
