Insert images of PDF pages: Insert an image of each page of the PDF at the beginning of the Form. Great for asking questions that involve referring to images.
PDF was scanned: If you scanned the PDF or took a picture and created a PDF, toggle this on to get better results.
Switch Text Image: For a few PDFs, the images will have blank text. If this happens to your PDF, toggle this switch on and Refresh. When this is toggled on, if your text turns to weird boxes, just toggle it off and Refresh :)
