Frequently asked questions
What kind of encryption is used?
The tool adds password protection using a standard PDF library. The specific encryption details depend on the library's implementation within the browser.
What happens if I forget the password?
We cannot recover it. The password is part of the encryption key and is never sent to us. Be sure to store it safely.
Can I set different opening and permission passwords?
This tool uses a single password to control both opening and permissions. The permissions you set will apply to anyone who opens the file.
Securing Your PDF Documents
Secure your PDF by adding a password required to open it. You can also set separate permissions to restrict printing, copying text, or modifying the document.
- Password-protect a PDF when sharing sensitive information. This ensures only authorised individuals with the password can access the document's contents.
- Setting permissions gives you more control. You can prevent recipients from printing, copying text, or making changes to maintain document integrity.
