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: TheAddTagsTo Documentcommandremovesanytagsthatwereinthedocumentbeforethecommandwasrun.

About the Add Tags Report

If Acrobat encounters potential problems while running the Adds Tags To Document command, the Add Tags

Reportopensinthenavigationpane.The reportlistspotentialproblemsbypage,providesanavigationallinktoeach

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

thesourcefileandaddaccessibilityfeaturesinthe authoringapplication.Repairing theoriginalfileensuresthat 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
