SmileOnMyMac has released a major update to PDFpen, their PDF editing software which we examined at a while back. PDFpen allows you to edit PDFs to fill out forms (e.g. scans of existing forms), mark-up documents, etc. The biggest new feature for version 4 is the inclusion of basic OCR functionality that will turn a scanned document into editable text. In addition there is support for new file formats including importing Microsoft Word documents.
PDFpen comes in two versions, a basic version for editing PDFs and a pro version that also allows you to create editable forms (i.e. forms that can be filled out by users with a PDF reader like Acrobat or Preview). PDFpen is $49.95 (or $99.95 for the pro version). Upgrades for to version 4 from previous version are $25. Demos for both standard and pro are available for download.
