PDF Tags provide information regarding the content of a document, such as the type of text, object, and their reading order. This is helpful when disadvantaged readers require assistive software to interpret and present a document to them in a logical fashion. Without tags, the software may be forced to guess the correct order and could lead to unpredictable results. Additionally, pictures or other visual aids require tagging as well, so they can be described in audio form.

The Tag panel

The Tag panel allows you to view and edit tags in the logical structure tree. The tags in the Tag panel are displayed in a hierarchical order which indicates the reading sequence of the document. The very first item in the panel is always the Tags root, and all other items are its children. Note that changes made to tag tabs cannot be undone by the undo command, so please make sure that you save a backup copy of the document before editing tags.

  1. To open the Tag panel, choose Document > Navigation > Tag, or on the sidebar navigation pane, click the Tag panel icon .
