Common questions

Which software opens the protected file?
Adobe Acrobat Reader, the PDF viewer in your web browser and other common readers open AES-256 files with the password. Readers released before 2008 may not be able to open them.
Can I restrict only printing or copying?
This tool sets an open password only. Once opened, the file can be printed and copied.
Can a forgotten password be recovered?
No. This website does not store the password, so it cannot be recovered. Please keep a copy of the original file without the password.
