Our thanks to Smile for sponsoring MacStories this week with PDFpen.

PDFpen is the premiere Mac app for editing PDFs to add signatures, text, and images, as well as make changes to correct typos. PDFpen can perform OCR (Optical Character Recognition) so that pictures of text in your document will be turned into real text that you can use. With support for cloud services, PDFpen can keep your documents available across OS X and iOS thanks to PDFpen for iPhone and iPad.

With version 6.1 of PDFpen, Smile added support for PDF stamps: you can now browse a library of standard business stamps (e.g. Approved, Confidential, Sign Here) to quickly apply to your documents without complex editing required. In this version, Evernote users can also save PDFs directly to Evernote Business notebooks.

PDFpenPro –  the advanced version of PDFpen – received some cool new features as well. The new version adds support for automatically detecting and creating form fields for an entire document (in addition to per page) and there’s a new “Create Links from URLs” command to detect and create links in a document.

PDFpen is available on the Smile Store and the Mac App Store. A free demo can be downloaded on the Smile site.
