You need certain information in the form of text from scanned copies of documents. Either you can write the whole text by typing or you can use an OCR Software. OCR (Optical Character Recognition) is method to extract text from images. It can recognize handwritten, printed or typewritten text and can produce them into editable word or text format. You can Download it here http://www.simpleocr.com/
These OCR software also preserve the formatting of the original scanned document into converted document. They are not 100% accurate and the converted document still requires some editing rather to type the whole Document. Earlier I have reviewed top Free OCR softwares. If you have Microsoft office installed in your computer then you won't need any other third-party software as you can use Microsoft Office OneNote to copy text from images.

4. Now Right-Click on the image and select Copy Text from Picture option, (THAT'S IT).
