FreePDF: The Automatic Bookmarks feature is not available in FreePDF.
FlexiPDF can create bookmarks automatically. This is practical for long PDF documents without bookmarks.
Proceed as follows:
| 1. | Use the ribbon command View | group Window | Sidebars  | Bookmarks to show the Bookmarks sidebar. |
| 2. | Navigate to the page from which bookmarks are to be created automatically. If, for example, you want to omit the table of contents at the start of a book, go to the first page after the table of contents. |
| 3. | Click on Automatic Bookmarks  at the top of the Bookmarks sidebar. |
| 4. | If the PDF file already contains bookmarks, FlexiPDF asks if you are really sure about removing the existing bookmarks. If you click on Yes, the bookmarks will be created. |
| 5. | Creating the bookmarks may take some time. You can cancel the process at any time by clicking on Stop. The bookmarks that were created up to this point are retained. |
If necessary, you can influence the creation of automatically generated bookmarks in such a manner that only text written in a specific font is considered. For more information, see the next section.
