How to Remove Tags From a PDFby Charlotte Mission
PDF files created in Adobe Acrobat contain elements of code called "tags" that tell PDF readers how to structure the information in the document. This structure includes the order of the pages and the placement of images, text and tables. Tags are often used to provide structure for PDF files that are read on PDAs and other portable devices and for use with assistive technology for blind or otherwise disabled people. If you do not want to use tags in a PDF file, you can remove them easily.
Open the PDF file. Click "View" in the menu bar at the top of the window.
Select "Navigation Panels" and then "Tags."
Click "Options" and select "Delete Tags." Click "OK" to save the settings.
