How to Automatically Create Bookmarks Named After PDF Pages
Question details
The user needs a method to generate one bookmark per page for a document exceeding 200 pages, specifically using each page's label as the bookmark name so that the file can be split later with accurate file names.
- Product
- PDF Editor
- Device & OS
- not provided
- Scenario
- Preparing a large PDF document to be split into multiple smaller files, ensuring each resulting file automatically inherits the correct name derived from the original page label.
- Observed behavior
- The user requires an automated or efficient batch-processing solution, as manually creating and renaming hundreds of bookmarks one by one is too time-consuming.
Always create a backup copy of your large PDF document before running automated scripts or bulk-processing tools, as these methods may permanently overwrite existing bookmarks or document structures.
Use JavaScript to Automatically Generate Bookmarks
Execute a custom JavaScript snippet within your advanced PDF editor to instantly loop through the document and create a bookmark for each page based on its label.
This method is highly efficient for documents with hundreds of pages. Note that some scripts may clear the existing top-level bookmark tree before generating the new bookmarks.
Open your PDF document in Adobe Acrobat or a compatible PDF editor, and launch the JavaScript Debugger console (often accessed via Ctrl+J or Cmd+J).
Input a script designed to loop through the document. The script should utilize the 'getPageLabel' method for each page index and generate a corresponding bookmark at the root level.
Close the console and open the Bookmarks navigation panel. Confirm that a bookmark has been created for every page and accurately reflects the page label.
Manual Method: Split, Batch Rename, and Re-Merge
A practical workaround for users who cannot use JavaScript, involving splitting the document, bulk renaming the files with a utility, and merging them back together.

Frequently Asked Questions
Why do scripts sometimes delete my existing PDF bookmarks?
Many JavaScript routines designed to build a new set of bookmarks start by clearing the existing top-level bookmark array to prevent duplication or messy hierarchies. Always verify the script's logic and work from a backup file.
Can I automatically create PDF bookmarks based on document formatting?
Yes. Many advanced PDF editors include an 'Auto Bookmark' feature that scans the document for specific text formatting, such as heading styles or font sizes, and automatically generates a structured bookmark list based on those elements.
How does having bookmarks help when splitting a PDF document?
When you choose to split a PDF document by its top-level bookmarks, the PDF software can automatically name each resulting file after the corresponding bookmark. This saves you the trouble of manually renaming hundreds of individual files after extraction.
