What is OCR software?
OCR software is capable of recognizing text characters in image files by using their optical properties. For documents that are not initially text-searchable, OCR software can convert them into a searchable, editable format. OCR works by comparing the text that it is processing to pre-existing samples, and identifying characters based on whether they match a previously stored pattern.
Why is OCR necessary for scanned PDF files?
Scanned PDF files are one example of a situation in which OCR is an extremely useful tool. PDF is a format that is frequently used to save documents containing scanned text, but the text remains inaccessible until OCR software is used to make it searchable and editable. OCR software therefore enables you to access text content in documents that were previously stored only as images.
