Add Password Protection to a PDF
Password protection is useful when you want a PDF to require a password before it can be opened. Upload the document, choose a password, and create a protected copy of the PDF.
The current protection process uses PDF encryption and writes the pages into a newly protected PDF. Keep the password somewhere safe because recipients will need it to open the protected document.
What This PDF Protection Does
The tool applies password-based encryption to the PDF. Its purpose is to restrict opening the document without the required password.
The current implementation does not configure separate restrictions for printing, copying, or editing, so password protection should not be described as a complete document-rights management system.
Choosing a PDF Password
Use a password that is difficult for other people to guess and avoid reusing an important account password. A longer password containing a mixture of characters generally provides better protection than a short or predictable one.
Share the password separately from the PDF when practical, especially when the document contains information that should not be publicly accessible.
Check the Protected File Before Sharing
After downloading the protected PDF, open it in a PDF reader and confirm that the expected password prompt appears.
Keep an original copy of important documents. Password protection creates another version of the PDF and should not replace your only copy of the source document.
Frequently Asked Questions
Yes. A password is required before the protection process can run.
