Question details
Users need to create clear, top-level bookmarks for each individual file when merging multiple PDFs into a single document.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Merging multiple PDF documents and trying to organize the combined file using bookmarks based on the original filenames.
- Observed behavior
- The combined PDF imports internal bookmarks from source files but fails to create top-level bookmarks for each file, or it generates incorrect GUID-based labels instead of proper names when processed online.
Before merging your PDFs, ensure that all source files are clearly named on your computer, as these filenames are typically used to generate the top-level bookmarks in the combined document.
Enable Automatic Bookmark Creation in Desktop Acrobat
Use the desktop version of the PDF editor to merge files and automatically generate bookmarks from the source documents, avoiding online cloud processing errors.
Processing files through online workflows or cloud services can sometimes assign GUID-based labels (long strings of letters and numbers) instead of actual filenames. Using the desktop application ensures the filenames are correctly converted into top-level bookmarks.
Launch your desktop Acrobat application, go to the Tools menu, and select 'Combine Files'.
Click 'Add Files' and select the PDF documents you want to merge. Arrange them in the correct order.
Click the 'Options' button (often represented by a gear icon) and ensure the setting to add bookmarks to the combined PDF is enabled.
Click 'Combine' to merge the documents. Once finished, open the Bookmarks panel to verify that the top-level bookmarks match your source filenames.
Manually Add and Reorganize Top-Level Bookmarks
If automatic creation fails or generates incorrect labels, you can manually construct the bookmark hierarchy in your combined PDF.

Frequently Asked Questions
Why are my combined PDF bookmarks showing as long strings of numbers and letters?
This usually happens when files are processed through certain online cloud services or automated workflows that assign system GUIDs instead of reading the original filename. Combining the files using a desktop application usually resolves this issue.
Can I keep the internal bookmarks from the original PDFs when merging?
Yes. Most professional PDF editors have an option in their 'Combine Files' settings to retain original bookmarks. These original bookmarks will typically be nested under a new top-level bookmark named after the source file.
How do I fix a broken bookmark link after combining files?
Open the Bookmarks panel, right-click the broken bookmark, and select 'Set Destination' or 'Properties'. Navigate to the correct page in the newly combined document and confirm the selection to update the link.
