- Product
- PDF Reader and Editor
- Device & OS
- not provided
- Scenario
- Attempting to apply security settings or edit a newly created PDF converted from a Word document.
- Observed behavior
- The PDF opens in read-only mode, and the Security Method is grayed out displaying 'No Security', preventing any permission changes.
Ensure the PDF file is saved locally on your computer and is not currently open in another program before attempting to change its view or security preferences.
Disable PDF/A View Mode in Preferences
PDF/A files automatically open in read-only mode to preserve document archiving standards. Disabling this view mode restores editing and security configuration capabilities.
When a document is created using the PDF/A standard, PDF readers automatically lock the document to prevent changes that might affect long-term preservation. You must disable this viewing mode to regain access to security settings.
Launch your PDF application and navigate to Edit > Preferences from the top menu bar.
In the Preferences window, select 'Documents' from the left-hand category list.
Find the 'PDF/A View Mode' section and change the dropdown setting for 'View documents in PDF/A mode' to 'Never'.
Click OK to save your changes. Close and reopen the PDF file, then go to File > Properties > Security to configure your desired editing restrictions.

Disable PDF/A Compliance during Word Conversion
Prevent PDFs from opening in read-only mode by disabling the PDF/A standard when converting them from Microsoft Word.
Manage PDF Security Effortlessly with WPS Office
WPS Office provides a comprehensive PDF toolkit that allows you to easily edit, convert, and secure your PDF documents without the confusion of locked archiving modes.
- 1. Open the PDF in WPS Office: Launch WPS Office and open your PDF file using the built-in PDF reader.
- 2. Access Security Tools: Navigate to the 'Protect' tab located on the top ribbon menu.
- 3. Apply Encryption: Click on 'Encrypt' to set an open password or restrict editing and printing permissions easily.
- 4. Save Changes: Click 'Confirm' and save the document to apply the new security parameters.

Frequently Asked Questions
Why does my PDF say 'Read-Only' at the top?
Your PDF may be marked as read-only because it was saved in PDF/A mode (used for long-term archiving), the file properties in your operating system are set to read-only, or the author applied specific editing restrictions.
How do I remove the read-only status from a PDF file system?
If the read-only status is a file system issue, right-click the file in Windows File Explorer, select Properties, uncheck the 'Read-only' attribute box at the bottom, and click Apply.
Can I add a password to a PDF/A document?
No, the PDF/A standard strictly forbids encryption and password protection to ensure the document can be accessed easily in the future. You must save the document as a standard PDF to apply security settings.
