Free OCR Software Convert Images To Text


In a layman’s term OCR – Optical Character Recognition is application software converting pictures or handwritten documents into computer readable text format. Extracting the text from an image or a scanned document so that it can be edited, formatted, searched, indexed, automatically translated or converted to speech. Meanwhile, OCR can be used to convert books and documents into electronic format and to automate various business processes.

However, OCR software may not be possible to obtain 100% precise text conversion, the OCR application strives to give something that is close to the scanned document. Some of OCR Software also comes with spell checker to guess some unrecognized words. So, below is the list of Free OCR software that I gathered.
