Frequently Asked Questions
What encryption standard is used?
The tool applies password protection using its PDF library. Check the resulting file’s security properties in a trusted PDF reader before relying on a particular encryption standard.
Will the file open in every PDF viewer?
Viewer support can vary. Test the protected file in the PDF reader your recipient plans to use.
Can I restrict printing or copying separately?
This tool sets an opening password; it does not offer separate controls for printing, copying, or editing.
What if I forget the password I set?
There is no way to recover it — that is what makes it secure. Write your password down in a safe place before adding encryption.
