Why should I password protect a PDF?

Password protection is essential for securing sensitive information. It prevents unauthorized access, editing, copying, or printing of confidential documents like contracts, financial reports, or personal records, ensuring your data remains private and secure.

How do I lock a PDF and make it uneditable?

In WPS Office, open the PDF, go to the 'Protect' tab, and click 'Encrypt'. Here, you can set a 'permissions password' specifically to restrict editing. This locks the PDF, making it read-only for users without the password, while still allowing them to open it.

What is the difference between an 'open password' and a 'permissions password'?

An 'open password' is required for anyone to view the document's contents. A 'permissions password' controls what a user can do after opening the file, such as editing, copying, or printing. You can use one or both to achieve the desired level of security.

Can I customize the security settings in PDF Protection?

Yes, WPS Office offers customizable security settings. When you encrypt a PDF, you can set a permissions password and then choose specific actions to allow or disallow, including printing (at different resolutions), making changes to the document, and copying text or graphics.

Can I remove a password from a PDF?

Yes, if you have the existing password. Open the password-protected PDF in WPS Office (entering the password if required), navigate to 'Protect' > 'Encrypt', and then uncheck the password settings. You'll be prompted to enter the current password to confirm and save the changes, effectively removing the protection.
