Do you need certain information in the form of text from scanned copies of documents or jpg files.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 recognise handwritten,printed or typewritten text and can reproduce them into editable word or txt format.
These OCR software also preserve the formmating of the orignal scanned document into converted document.They are not 100% accurate and the converted document still requires some editing.But it is better to use an OCR software and do some editing rather to type the whole Doument.
