Frequently asked questions
What are the limits of Protect PDF?
Copying and printing restrictions depend on the reader honoring them and cannot prevent screenshots. The tool cannot recover a forgotten password.
How should I check the Protect PDF result?
Test a wrong password and the correct one in another viewer. Keep an accessible original securely and check encryption support if a recipient cannot open it.
