A doc scanner is a software application or camera device that is used to scan digital or paper documents and convert them into images or digital text files. These scanners are widely used in offices, libraries, and archives to digitize traditional paper documents such as contracts, agreements, receipts, and invoices making them easy to store, search, and retrieve. Doc scanners can save time, improve efficiency, and reduce clutter by eliminating the need for paper copies, making them an essential tool for the modern workplace.

They use different technologies such as flatbed, sheet-fed or handheld scanners, and can output different file formats such as PDF, JPEG or TIFF. Some document scanners may also come with software that automatically converts the scanned images into text that can be edited or copied.
