There is actually a very quick workaround to this, though, that takes very little effort (literally, a few seconds) and no additional file space or converting the file - everyone can figure it out. Converting one page to a tiff image as you suggest, while it may work, creates too big a file to email, and takes too much time when you need to get a document or form updated and signed and out the door. Everyone who uses Acrobat DC knows that you can add text to it and once you save the file, afterward (seconds later) you almost always will discover that some of that text just entered is now uneditable. I'm sorry but this is not a helpful answer. a 600dpi TIFF image), and then import this image again into Acrobat (and therefore converting it to PDF), and then running OCR on that. Your only option in this case is to convert the complete page (or the complete documents) to a high resolution image file (e.g. In this case, the text was converted from true text (which you can edit) to vector drawings, that have nothing to do with text anymore (but still look like text). If OCR does not work, chances are you are dealing with text that was converted to 'outlines'. Otherwise you end up with text that is stored 'behind' the original image. The important thing here is to run OCR with the 'Editable Text and Images' setting in the OCR settings. In this case, you can very likely (this depends on the quality of the image) run OCR and then after that you should be able to edit this text. The most common problem is that you are actually looking at an image or a picture of text. There are different reasons why something that looks like text does not behave like text.
