Gray boxes adjacent to text and images after conversion from Word
I converted Word 2013 file to PDF by using Save As PDF in Word. The entire file displayed large, light gray rectangles adjacent to the text on each page. (See attached image.) The solution to remove those rectangles was to delete comments that appeared in the Word document and save it as a PDF, again. There was only one comment in the Word file that got there by accident, but it caused hours of frustration for me. Once it was removed, the conversion worked like a charm.
To remove comments, in Word, go to Review, Delete Comments.
That is expected behavior with Word files having comments. Great to hear that it is resolved for you.
