How to OCR a PDF on a Mac: A Comprehensive Guide

Optical Character Recognition (OCR) is a powerful tool for converting scanned text into editable, searchable text within PDF files. Whether you are working with personal documents, official records, or any other type of PDF on your Mac, this guide will walk you through several reliable methods to achieve OCR. Let's explore how to OCR a PDF file on a Mac and the best tools you can use for this task.

Understanding OCR and Its Importance

OCR, which stands for Optical Character Recognition, is a technology that recognizes characters in scanned images and converts them into machine-encoded text. The significance of OCR lies in its ability to make PDF files that originally contained only images of text into searchable and editable documents. This is particularly useful for documents that have been scanned rather than typed, making them difficult to search or edit normally.
