Optical scanning is a technology that converts physical documents and images into digital formats. This process typically involves using a device called a scanner, which captures the visual information and transforms it into a digital file that can be stored, edited, or shared. Optical scanning is commonly used in offices, libraries, and homes to digitize paperwork and photographs. The scanned images can be saved in various formats, such as JPEG, PDF, or TIFF. Optical scanning is essential for document management, archiving, and preserving historical records, making it easier to access and retrieve information without the need for physical storage.
