What does it mean to OCR a PDF image?
When you OCR a PDF image, you transform the PDF file from a simple image to a fully searchable, editable text document that you can work with just like with any other text file. OCR stands for optical character recognition, meaning that it can identify scanned text characters using algorithms based on optical features.
The accuracy of OCR software varies greatly from one product to the next. However, you may be reassured to know that the better OCR products are generally very accurate, with some reaching near-perfect accuracy levels. The accuracy of the software also depends on the quality of the image file and the features that the program has for dealing with different levels of quality.
