Removeing sensitive content Adobe Acrobat Pro PDF

Why redact or remove sensitive content?

Before you distribute a PDF, you may want to examine the document for sensitive content or private information that can trace the document to you. Use the Redact tools to remove or redact sensitive images and text that are visible in a PDF.

Use the Remove Hidden Information feature to find and remove hidden content from a PDF. For example, if you created the PDF, the document metadata normally lists your name as the author. You may also want to remove content that can inadvertently change and modify the document’s appearance. JavaScript, actions, and form fields are types of content that are subject to change.

Password security basics Adobe Acrobat PDF

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 type a password to open the PDF.

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. Because of the added security, setting both types of passwords is often beneficial.
