One of the interesting new features is the ability to convert a PDF to Microsoft Word format. This is done via the Nuance OmniPage Cloud Service, which works amazingly well. Conversion from PDF format is not my first choice of workflow, but it’s good to know that it’s possible in a pinch.
The direct sale version of PDFpen 5.7 could access iCloud via the PDFpen Cloud Access app. This helper app is no longer available, so iCloud support is now available only if you purchased PDFpen from the Mac App Store.
