Lighten PDF Security Manager

The fact that the free version of Adobe's PDF reader doesn't offer too much in terms of editing doesn't mean that a PDF's contents are safe from intellectual property theft. Lighten PDF Security Manager gives you the possibility of protecting PDFs with a password. The application can also restrict certain functions for your PDFs, which means that people can view them without being able to edit or copy anything.

The application is free to try for a limited period of time, but without any functionality restrictions. It doesn't take long to download and install the application. Also, there is no need to meet any special requirements or to sacrifice too many resources.

Lighten PDF Security Manager comes with a compact user interface, which presents only a few simple controls. Adding protection measures for one or more PDFs is quite simple. All you have to do is load them onto the user interface, select one of them and click a Settings button to bring up a series of security options on a separate window. Once your settings are complete, you only need to click a Start button to apply them to your files. Also, you can choose to save the modified files in a specific folder, so the originals will remain untouched.

As previously mentioned, the software can password-protect PDFs. This means that no one will be able to open them without the correct password. Additionally, you can choose to disable the Copy and Print options for the targeted files and prevent or limit general changes. Furthermore, the application lets you apply the settings to the currently selected file or to all of them.
