- Product
- PDF Editor
- Device & OS
- not provided
- Scenario
- Combining multiple PDF documents that contain existing bookmarks and internal links into one file.
- Observed behavior
- Bookmarks stop working, fail to point to correct page destinations, or document structures are not preserved correctly during the combination process.
Before merging your PDF files, ensure that all original documents have functioning bookmarks and that you are using the latest version of your PDF editing software.
Use Official Combine Tools and Recreate Bookmarks
Ensure you use the built-in merge tools of your PDF editor and manually update the bookmark destinations if they are shifted during the merge.
When merging PDFs, basic or third-party tools might flatten the document structure, stripping away interactive elements. Using the dedicated combine feature in a professional PDF editor preserves these structures better.
Check for updates in your PDF software (such as Adobe Acrobat) and install the latest version to ensure bug fixes related to merging are applied.
Navigate to the 'Tools' menu and select 'Combine Files' rather than using a basic insert page or print-to-PDF method.
Once the document is merged, open the Bookmarks navigation pane on the left side of the screen.
Right-click any bookmark that does not work, select 'Properties' or 'Edit Destination', scroll to the correct page in the new document, and save the updated destination.

Regenerate Original PDFs with Bookmark Options Enabled
If the original PDFs were exported from Microsoft Word, regenerating them with the correct export settings can resolve underlying hyperlink issues.
Merge PDFs and Preserve Bookmarks Automatically with WPS Office
WPS Office includes a robust PDF toolkit designed to seamlessly merge multiple PDF files while automatically retaining your original bookmarks, internal links, and document structure without the hassle.
- 1. Open WPS PDF: Launch WPS Office and open the WPS PDF tool from the main dashboard.
- 2. Select the Merge tool: Click on the 'Page' or 'Tools' tab and select the 'Merge PDF' feature.
- 3. Add your files: Import all the PDF documents you wish to combine and drag them into your preferred order.
- 4. Merge and verify: Click the 'Merge' button to generate the new document. Open the Bookmark pane to easily verify and manage your fully preserved bookmarks.

Frequently Asked Questions
Why do bookmarks disappear when merging PDFs?
Bookmarks often disappear because the merging software fails to preserve the internal document structure or page destinations. Using outdated software or basic online merge tools can strip these advanced interactive elements during the conversion process.
Can I edit or fix bookmarks after merging PDFs?
Yes. Most professional PDF editors allow you to edit bookmarks post-merge. You can open the bookmark navigation panel, right-click the broken bookmark, and manually update its destination to the correct page in the newly combined document.
Does converting Word to PDF affect my bookmarks?
Yes, if the export settings in Word are not configured properly, bookmarks generated from headings won't be saved in the PDF. Always ensure 'Create bookmarks using Headings' is checked in your PDF export options before saving and subsequently merging.
How can I keep hyperlinks intact when combining PDFs?
To keep hyperlinks intact, use dedicated desktop PDF merging software like WPS PDF or Adobe Acrobat rather than 'Print to PDF' functions. Print functions flatten the document and permanently remove clickable hyperlinks and bookmarks.
