- Device & OS

- Scenario
- Organizing a large document by splitting chapters or specific sections into individual files.

- The user needs to extract sections of a PDF document into separate files where each output file corresponds to a top-level bookmark.
Ensure your PDF document already contains top-level bookmarks marking the exact start of each section or chapter you wish to separate.
Split by Top-Level Bookmarks Using the Organize Pages Tool
Use the built-in Organize Pages tool in Adobe Acrobat Pro to automatically scan for bookmarks and generate individual PDF files for each section.
This method leverages Acrobat's native splitting function, which recognizes existing top-level bookmarks in your document and uses them as precise dividing points to create new, separate files.
Launch Adobe Acrobat Pro and open the large PDF file you want to split.
Click on 'Tools' in the top menu and select 'Organize Pages', or choose it directly from the right-hand pane.
In the secondary toolbar that appears, click the 'Split' button.
Open the 'Split by' drop-down menu and choose 'Top-level bookmarks'.
Click 'Output Options' to specify the destination folder for the new files and customize the file naming conventions, then click 'OK'.
Click the 'Split' button. Acrobat will notify you once the separate PDFs have been successfully created.

Frequently Asked Questions
Why is the 'Top-level bookmarks' option greyed out in Acrobat?
This option is only available if the PDF document currently contains saved bookmarks. You must manually add top-level bookmarks to the document via the Bookmarks panel before attempting to split it.
Can I split a PDF by file size instead of using bookmarks?
Yes. In Adobe Acrobat Pro's Split menu, you can change the 'Split by' dropdown option from 'Top-level bookmarks' to 'File Size' and specify the maximum megabytes allowed per file.
Will the split PDF files retain their original formatting?
Yes, dividing a PDF by bookmarks simply separates the designated pages into new files while preserving all text, images, hyperlinks, and layout formatting exactly as they appeared in the original document.
How do I create top-level bookmarks before splitting the PDF?
Open the Bookmarks panel on the left side of Adobe Acrobat. Scroll to the page you want to mark, click the 'New Bookmark' icon (or press Ctrl+B), and type a name. Ensure it is not nested under another bookmark to keep it top-level.
