OCR PDF benefits
Having the ability to OCR PDF files is useful in many contexts. If you work with paper documents, then it is likely that you need to scan some of them in order to coordinate with the increased use of digital files. Scanned documents are not text-searchable, however. Thanks to OCR software, you can instantly convert your scanned PDF files into text-searchable documents.
The requirements for optical character recognition are very basic. All you really need to do is select an OCR program and install it on your computer. Then, you can take virtually any PDF file and OCR it. Different OCR programs require different levels of quality from the original document, meaning that if the image quality is poor, you might not obtain accurate results. However, overall OCR software is extremely accurate.
