OCR (Optical Character Recognition) is a technology that enables you to convert different types of textual documents, such as scanned paper documents, PDF files or images captured by a digital camera into editable and searchable data.
When OCR converts a scanned image into digital text, it becomes a searchable text file, thus making navigation much easier.
You could quickly find the page number of a favorite quote or locate all the uses of certain keyword within a large document, for example.
You can also copy, paste, and edit passages of text within the document.
Documents can be converted to digital text using OCR software such as Adobe Acrobat Pro DC.
