PDFs must be tagged in order to specify the document's correct reading order and indicate the different types of content within a document. PDFs need tags in order to describe the document's logical structure and the relationships between elements for users of assistive technology.

To fix this issue automatically, right-click "Tagged PDF" on the Accessibility Checker panel and then choose "Fix" from the Options menu. Acrobat automatically tags the PDF. These tags must be reviewed to ensure that they are correct. If these tags are not correct, use the Reading Order tool to edit or repair tags. 

A user selects the auto-tag tool to add tags to a PDF in Adobe Acrobat Pro.

Though you can correct most tagging issues by using the Reading Order tool, you must use the Tags panel to address detailed tagging of tables and substructure items, such as paragraphs, lists and sections that require multiple languages. Below you will find basic instructions on how to manually edit tags in the Tags panel using Adobe Acrobat's Accessibility tool.

  • Add or edit a tag title: Right-click a tag, choose "Properties" from the Options menu, enter text in the "Title" box and click "Close."

A user adds a tag title to an element in a PDF's tag tree using the Adobe Acrobat Pro program.

  • Change the element type: Expand the section of the logical structure that you want to change. Right-click an element and choose "Properties" from the Options menu. Choose a new element type from the "Type" menu and click "Close."

A user changes a tag type in a PDF's tag tree using the Adobe Acrobat Pro program.

  • Move a container or object: Click and drag or cut and paste the item within the tags structure.

A user moves a tag using the drag-and-drop and cut-and-paste methods in the Adobe Acrobat Pro program.
