Question details
The user needs to merge multiple source documents into a single PDF and wants to automatically create bookmarks or an interactive table of contents to easily navigate the combined file.

- Product
- Adobe Acrobat DC
- Device & OS
- not provided
- Scenario
- Transitioning from pdfDocs Binder to Acrobat DC to merge files, convert formats, and create a structured navigation system using bookmarks and a TOC.
- Observed behavior
- Requires a specific workflow to ensure source files convert properly to PDF format while preserving or automatically generating a bookmark hierarchy based on source formatting.
Before combining your files, ensure that any source word processing documents (like Microsoft Word) are formatted using proper Heading styles, as this helps PDF editors automatically recognize and generate structural bookmarks.
Combine Files and Auto-Generate Bookmarks in Adobe Acrobat DC
Use Adobe Acrobat's 'Multiple Files' creation tool to merge documents and automatically generate bookmarks based on file names and source document heading styles.
Acrobat provides powerful options when combining files. You can choose to merge them into one continuous PDF (which converts all files to PDF format) or create a PDF Portfolio (which preserves each file in its native format). When combining into a continuous PDF, Acrobat can generate structural bookmarks for you automatically.
Launch Adobe Acrobat DC, navigate to the 'Tools' tab at the top left, and select the 'Create PDF' option.
Click on 'Multiple Files' from the list of creation options, and then choose 'Combine Files'.
Click the 'Add Files' button to browse and select the source documents you wish to combine. Once added, you can drag and drop the files to arrange them in the correct order.
Click on the 'Options' button (represented by a gear icon on the toolbar). In the settings menu that appears, check the box labeled 'Always add bookmarks to Adobe PDF' and click OK.
Click the 'Combine' button at the top right. Acrobat will merge the files and generate bookmarks for each included document, as well as additional section bookmarks if the source files utilized proper heading styles.

Frequently Asked Questions
Why didn't my Word document sections become bookmarks in the combined PDF?
This usually occurs if the original Microsoft Word document was not formatted using built-in Heading styles (such as Heading 1, Heading 2). For a PDF software to automatically generate section bookmarks, the source text must be properly styled as headings rather than just enlarged, bold text.
What is the difference between a combined PDF and a PDF Portfolio?
A combined PDF merges all source documents into a single, continuous PDF file, converting non-PDF formats (like Word or Excel) into standard PDF pages. A PDF Portfolio acts like a digital binder, grouping files together while maintaining their original native formats, meaning a Word document remains an editable Word file inside the portfolio.
Can I manually edit or create a Table of Contents after combining PDFs?
Yes. If the automatic generation does not capture the structure exactly as you want it, you can open the Bookmarks navigation pane in Acrobat or WPS PDF to manually add, rename, delete, or nest bookmarks. You can also use text and link tools to design a traditional, clickable Table of Contents page at the beginning of your document.
