Tag panel

Tagged PDF files contain metadata that describes the document structure and the order of the different document elements (such as pictures, text blocks, columns, titles). This makes it easier to extract text or graphics from PDF files, and helps screen readers to present the file content in the correct order. Accessibility standards may require PDF files to be tagged.

The Tag panel is available from the Panel bar when you select the following tool:

If you do not see this tool, right-click in an empty area of the Panel bar and select it.

The Tag panel displays the document tags in a tree-type structure. When navigating through the tree to verify if the order and hierarchy of the tags is appropriate, you can optionally highlight associated content nodes.

The tag menu (structure display and tag-associated operations) is accessible either by right-clicking a tree node or by using the Options menu at the top of the panel.

Tag menu and commands

Options icon Use the Options list to access more commands:

  • New Tag: Creates a new tag at the current tag hierarchy position.

  • Cut: Cuts the selected tag.

  • Paste: Pastes the cut tag after the selected tag node.

  • Paste Child: Pastes the cut tag under the selected tag.

  • Delete Tag: Removes the selected tag.

  • Create Tag from Selection Only available after you have selected some PDF element with the Edit tool placed on the Edit ribbon. Inserts a new tag based on the selection.

  • Highlight Content: Shows which file content is covered by the current tag.

  • Properties: Displays the Object Properties dialog box. When you use it on a tag, it lets you edit the tag, attribute objects and classes. Using it on assigned content additionally lets you edit the container tag type and properties, or text attributes. It lets you view or change alternate texts or expansion texts for tagged objects. Alternate texts are used by screen readers to announce and describe graphic objects on the page.

Create tags root (only available for untagged PDFs): Creates the root object of the tag tree. This is the only menu item in the drop-down list under the Options menu (at the top of the Tags panel) for a non-tagged PDF. Use it to start building up a tag structure manually. Once the root is created, other commands become available in the drop-down menu.
