Have you ever opened a PDF file only to find that none of the information is searchable? In this tutorial, you'll learn how to convert a scanned document into a fully searchable PDF file using Acrobat X or XI. You'll also learn how to apply OCR, which stands for Optical Character Recognition. To apply OCR, the original scanner resolution must be at least 72 dpi or higher. In the Recognize Text dialog, you can set various capabilities like OCR language and PDF Output Style. There are three different PDF Output Styles you can select.
