How to Remove Permissions and Passwords From PDF Files
Website owners use PDF files to distribute information to readers. PDF files have security permissions and password protection capabilities, so users are only able to read the files without changing the content. This is useful for read-only content such as user guides, e-books and contracts. To edit the file, the password can be removed or user permission restrictions removed. Removing the password automatically opens the PDF file from its restrictions, and it can be done in the PDF file settings.
Hold the "Shift" key on your keyboard and right-click the PDF file. When the menu appears, click "Open With" from the options. This lists the applications for the PDF file. Select "Adobe Acrobat" to open it with your editor.
Click the "Settings" main menu item. Click "Security" to open the security properties for the file. Click "Remove Security" to remove the password and permission restrictions on the file.
Select "No Security" from the opened window. Click the "OK" button. Enter the old password for the file. This is used to authorize the changes on the PDF.
Click "Ok" again on the main security window. The password and permission restrictions are removed from the file.
