A document scanner is a device that converts physical documents into digital format. It captures the text and images on paper and saves them as files on a computer or cloud storage. This process makes it easier to organize, share, and store important information without taking up physical space. There are various types of document scanners, including flatbed scanners, sheet-fed scanners, and portable scanners. Each type serves different needs, from scanning single pages to handling multiple documents quickly. Many modern scanners also offer features like OCR (Optical Character Recognition), which allows scanned text to be edited and searched.
