PDF files that can be OCRed
Text recognition is not necessary for all scanned documents, and is only helpful for files that contain significant amounts of text. OCR, or optical character recognition, is a technology that recognizes text based on its optical properties, and converts it into digital information that can be recognized by a computer. If you scan books, forms, or other text documents, OCR is a great way to avoid having to retype information, and have the text conveniently accessible.
Steps to take for OCR
In order to OCR a PDF file, the first thing you need to do is to make sure that you have the right software. Browse the market, select an OCR product, and install it on your computer. You can try free online OCR tools, but those lack the accuracy of professional OCR tools. Once you have an OCR program, scan the documents that you would like to convert into PDFs, and select the scanned files for OCR. The process is simple and automatic.
