If adding tags to a PDF in Adobe Acrobat results in a tagging structure that is overly complicated or too problematic to fix, you can use the TouchUp Reading Order tool to remove or replace the current structure. If the document contains mostly text, you can select a page and then remove headings, tables, and other elements to create a cleaner, simpler tagging structure.
Acrobat can retag an already tagged document after you first remove all existing tags from the tree.
Remove all tags from a PDF
Replace the existing tag structureThis procedure works best in pages that contain a single column of text. If the page contains multiple columns, each column must be selected and tagged individually.
