SmileOnMyMac has released an upgrade to its PDF editing tool with Optical Character Recognition (OCR) technology, PDFpen 4.5. The latest version integrates Nuance Communication’s OmniPage 15.5 OCR engine, delivering improved accuracy when performing OCR on scanned documents. Other changes include the ability to scan directly into PDFpen from either Image Capture or TWAIN scanners when using a Mac OS X 10.6 operating system, along with a new text-highlighting function which enables simultaneous selecting and highlighting of text within a single action.

PDFpen comes with a wide variety of editing tools for adding text, images and signatures to a PDF, as well as copying specific text across multiple columns. It also comes with a built-in library for saving images, objects, signatures or text for organization and later use.

Additionally, all changes made to the PDFpen are also incorporated in the Pro version of the software, which has the ability to create fillable forms and a document table-of-contents.

PDFpen requires Mac OS X 10.4 or later to run, and is priced at $50 for the Standard version or $100 for the Pro. Users can upgrade from previous versions of the software for $25, or switch from the Standard to Pro version for $50.
