About Protect PDF
Protecting a PDF adds a password requirement to open the file, which is a straightforward way to keep sensitive documents — contracts, financial statements, personal records — private when sharing them over email or storing them somewhere others might access.
This tool focuses on setting an open password: whoever has the file needs the password to view it at all. Anyone sharing the resulting file should share the password through a separate, secure channel rather than alongside the file itself.
