Lesson 3. Creating Adobe PDF Files > Adding security to PDF files

Adding security to PDF files

When you share confidential documents by e-mail or on the Web, it is critical that the information doesn't end up in the wrong hands. Acrobat allows you to apply different levels of security so that only designated people can open files or only certain people can open and edit files. Even if your files are being distributed widely, you can protect them against being copied or changed. For example, now that you have a finished PDF file for the flyer, you'll want to protect the file from accidental changes before you send it to the printer.
