Use the Content panel to correct reflow problems in a PDF that cannot be corrected by using the Touch Up Reading Order tool. Take note that it is easy to damage a PDF by editing content objects as removing a content object will remove the object from the visual page. Be familiar with the PDF structure before changing anything. For comprehensive information about PDF structure, refer to the PDF Reference First Edition: Adobe Portable Document Format Version 1.7, on the PDF reference page (English only) of the Adobe website.
The Content panel provides a hierarchical view of the objects that make up a PDF, including the PDF object itself. Each document includes one or more pages, a set of annotations (such as comments and links), and the content objects for the page, consisting of containers, text, paths, and images. Objects are listed in the order in which they appear on the page, similar to tags in the logical structure tree. However, objects in the Content panel do not require tags to view or change the object structure.
To display the Content panel, choose View > Show/Hide > Navigation Panes > Content from the Acrobat DC menu.
Click the plus sign (+) (Windows) or the triangle (Mac OS) next to the document name to view each page content entry. Control + click expands the entire content tree. The Content panel provides an option to show the corresponding tag in the Tags panel by activating the context menu and choosing “Show in Tags Panel”.
