Optical Character Recognition (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document.

Text-R: Simple optical text recognition (OCR) for Windows. The problem: PDF files and images from a scanned paper document contain text that cannot be copied or edited. However, manual typing is not possible due to the size of the document and the high time involved.
