Password Protect PDF

Protect PDF files with a password to keep sensitive data confidential

Protect PDF

Protecting a PDF file typically involves adding a password to the file so that only authorized users can view or edit the content. There are several methods you can use to protect a PDF:

Using Adobe Acrobat: Open the PDF in Adobe Acrobat. Go to the 'Tools' pane and select 'Protect.' Choose 'Encrypt,' then 'Encrypt with Password.' Confirm that you want to change the document security. Set your password and permissions, then save the document.

Using Command Line (Linux): If you're using a Linux system, you can use the pdftk command-line tool to password-protect a PDF: 'pdftk input.pdf output output.pdf user_pw YOURPASSWORD' Caution: Remember that the strength of your PDF protection is only as good as the password you choose. Use a strong, unique password and never share it with anyone you don't trust.
