Make sure your PDF files stay secure by encrypting them. By setting a password on your PDF documents, they cannot be opened by other people unless the password that you set is provided.
You can also set permissions, so that a password is only required to make certain changes to your PDF document.
Easily set a password by opening your PDF document in PDF Converter, then click Set Password under the Security tab.
Create and confirm your password to apply it to the document. Then, when you save the document, it will be protected by your password. Your password will then need to be provided any time somebody wishes to open the file.
If you've previously set a password on a PDF file, you'll need to provide the password to open the document in PDF Converter.
Once opened, you can remove the encryption from the file by hitting the "Remove Password" button under the Security tab.
Simply click Yes in the confirmation box to remove the password. Once you save the document, the password removal will be applied, and a password will no longer be needed to access your file.
