Making existing PDFs accessible
Add tags to an existing PDF
Creating a tagged document directly from an authoring application is the best way to make PDFs accessible.
However, if a PDF was created without tags, you can add them using Add Tags To Document.
1 Open the PDF.
2 Choose Advanced > Accessibility > Add Tags To Document.
After the process is complete, the PDF is tagged and—if any potential problems were encountered—the Add Tags
Report appears in the navigation pane.
Note: The Add Tags To Document command removes any tags that were in the document before the command was run.
About the Add Tags Report
If Acrobat encounters potential problems while running the Adds Tags To Document command, the Add Tags
Report opens in the navigation pane. The report lists potential problems by page, provides a navigational link to each
problem, and offers suggestions for fixing them.
You should assess the context of an error before following a particular suggestion for fixing it. For example, the report
might state that an element that has been tagged as a figure requires alternate text to make it accessible. When you
examine the figure in its context on the page, you may decide that the figure is a background design element, not an
illustration that conveys valuable meaning to the user. In the case of a nonessential image, you would change the
Figure tag to a Background tag; in the case of an image intended to convey meaning to the reader, you would add the
missing alternate text.
Note: The Add Tags Report highlights tagging-related problems only, and it is a temporary file that you cannot save. You
can assess other tagging, reading order, and accessibility problems by using Full Check.

TouchUp Reading Order tool overview
The TouchUp Reading Order tool provides the easiest and quickest way to fix reading order and basic tagging
problems. When you select the TouchUp Reading Order tool, a dialog box opens that lets you see overlay highlights
that show the order of page content. Each highlighted region is numbered and highlighted with gray or colored
blocks; the number indicates the region’s placement in the page’s reading order. After you check the reading order of
the page, you can correct other, more subtle tagging issues as needed.
The TouchUp Reading Order tool is intended for repairing PDFs that were tagged using Acrobat, not for repairing
PDFs that were tagged during conversion from an authoring application. Whenever possible, you should return to
the source file and add accessibility features in the authoring application. Repairing the original file ensures that you
don’t have to repeatedly touch up future iterations of the PDF in Acrobat.
You use the TouchUp Reading Order tool to perform the following accessibility tasks:
• Visually check, and then repair, the reading order of page content
• Tag fillable form fields and their labels
• Add alternate text to figures and descriptions to form fields
