This isn’t some new feature in Acrobat, but I think it’s one of which not many people are aware (I learned this today).
Say you have a PDF that’s a scan, not originally typed. So it’s all image-based (raster). But, you want to use the text. Essentially, you need to do some OCR (optical character recognition) work.
You could print it out, and scan it into an OCR application. Or, you could just use Acrobat’s Paper Capture feature.
As long as the resolution of the PDF is 200 dpi or more, you can just select Document… Paper Capture… Start Capture. In the options, make sure the “PDF Output Style” is “Formatted Text & Graphics.” Once done, you could save it as a Word document for easier editing, or whatever floats your boat.
