It’s safe, free and easy to add password and permissions to your PDF files

Free pdf service for adding passwords and permissions to PDF files. No advanced options on par with Adobe Acrobat. It is WowTron PDF Encryption which is a powerful pdf encryption software.

You can limit access to a PDF by setting passwords and by restricting certain features, such as printing and editing. However, you cannot prevent saving copies of a PDF. The copies have the same restrictions as the original PDF. Two types of passwords are available:

Document open password: A Document Open password (also known as a user password) requires a user to add password to pdf file.

Permissions password: A permissions password (also known as a master password) requires a password to change permission settings. Using a permissions password, you can restrict printing, editing, and copying content in the PDF. Recipients don’t need a password to open the document in Reader or Acrobat. They do need a password to change the restrictions you’ve set.

If the PDF is secured with both types of passwords, it can be opened with either password. However, only the permissions password allows the user to change the restricted features.If you want to add password to pdf document, please use WowTron PDF Encryption:https://wowtron.com/pdf-encryption/index.html.
