How do I use Ally to convert a scanned PDF into readable text?

You will learn how to use Blackboard Ally to convert a scanned (image) PDF ,of a book chapter, for example, into a readable text PDF.

As part of the effort to make our courses as inclusive as possible, we should not have any files or documents which are not viewable/readable by all of our students. Follow these steps to convert your image PDF into a text PDF.
