How to Password Protect Your PDF?
Securing your document takes just a few simple steps:
- Upload your PDF file using the "Upload PDF" button.
- Set Password - Enter a strong password in the left panel.
- Adjust Permissions - Control printing, copying, and editing options.
- Download - Click "Protect PDF" to download your secured file.
Understanding Password Types
Our tool supports two types of passwords for maximum flexibility:
- User Password - Required to open and view the PDF document.
- Owner Password - Provides full control over the document, including the ability to change permissions.
If you set only a user password, anyone with that password can view the document but permissions will be restricted based on your settings. If you set both passwords, the owner password allows changing these restrictions.
