Fix 'Page Extraction Not Allowed' When Combining PDF Files
Question details
The user is unable to combine multiple PDF documents because the software blocks the action, stating that page extraction is not allowed for one or more of the source files.

- Product
- Adobe Acrobat / PDF Editors
- Device & OS
- not provided
- Scenario
- Attempting to merge or combine multiple PDF files into a single document.
- Observed behavior
- An error message appears indicating that page extraction is not allowed, which stops the merging process due to security restrictions on the source PDFs.
Ensure you have the owner or permissions password for any restricted PDF files, as you will need it to unlock the documents before they can be merged.
Check and Remove PDF Security Restrictions
Identify which source PDF has page extraction disabled and remove its security protection using the owner password.
PDF files can be locked with a permissions password (owner password) that restricts actions like editing, copying, and extracting pages. Even if you are the creator of the document, you must manually remove these security settings before the file can be combined with others.
Open the source PDF file in your PDF viewer or editor. Go to the 'File' menu and select 'Properties' or 'Document Properties'.
Navigate to the 'Security' tab. Look for 'Page Extraction' in the document restrictions summary. If it is marked as 'Not Allowed', this file is causing the error.
Click on the 'Security Method' drop-down menu and select 'No Security'. When prompted, enter the permissions (owner) password for the document.
Save the unlocked PDF document. Repeat this process for any other restricted files, then try combining the PDFs again.

Request an Unrestricted Copy
If you do not have the required permissions password, you must obtain an unprotected version of the file from the original author.

Frequently Asked Questions
Why does a PDF say I cannot extract pages even if I created the file myself?
If you applied permission passwords (owner passwords) to restrict editing, copying, or printing during the file's creation, those exact same restrictions will block page extraction. You must remove the security settings using your password before combining it.
Can I combine secured PDFs without the owner password?
No. If a PDF is protected against page extraction or document assembly, you must enter the owner password to remove the restriction before merging it with other files. If you do not have the password, you need an unrestricted copy from the author.
How do I check if my PDF has restricted permissions?
Open the PDF, go to the document's 'Properties' (usually found under the File menu), and look for the 'Security' tab. Here you will see a detailed list of allowed and restricted actions, including 'Page Extraction' and 'Document Assembly'.
Is 'Page Extraction' the same as 'Document Assembly'?
They are related but distinct permissions. Document Assembly allows a user to insert, rotate, or delete pages, while Page Extraction allows a user to pull pages out to create a new document. Combining PDFs usually requires both permissions to be allowed on the source files.
