Scanned PDF documents can be challenging for some PDF tools. While these type of documents can be opened and read most of the times, they can not be edited as easily as a PDF document that was created on your computer. The reason is quite simple: All your scanner does is take a photo of your document, which is why it's not recognized as text but as an image.
But don't you worry, we have a solution! PDF Director Pro includes a so-called Optical Character Recognition (OCR) module that analyzes scanned documents for texts and images. It allows you to copy and paste the text of the document into a new Word or PDF, from where you can make allt he changes you need.
