Our thanks to Smile for sponsoring MacStories this week with PDFpenPro 6.

PDFpenPro is the advanced version of PDFpen. PDFpenPro does everything that PDFpen does, such as add signatures, edit text and images, perform OCR on scanned documents and export Microsoft Word documents. It also has the ability to create a PDF form, build a table of contents, and convert HTML files to PDF.

The new PDFpenPro 6 adds document permission settings. When you share a PDF, you can restrict printing, copying, and editing of your PDFs. You can also use the new automatic form field creation tool to convert a non-interactive form into an interactive PDF form with text fields and checkboxes automatically added. PDFpenPro 6 is optimized for the Retina Display and now takes advantage of Versions and Auto Save available in Lion and Mountain Lion, which better saves your edits from accidental loss.

PDFpenPro 6 is available on the Smile Store and the Mac App Store for $100. A free demo can be downloaded on the Smile site. Find out why Macworld calls PDFpenPro “the crème de la crème of PDF editing and annotating applications.”
