Removing sensitive content
Preparing PDFs for distribution
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. Such information may be hidden or not immediately apparent. For example, if you
created the PDF, the document metadata likely 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. If your document doesn’t require
these items, remove them before you distribute the document. You can use the Examine Document command to find
and remove hidden content from a PDF.
To remove sensitive images and text that are visible in a PDF, use the Redaction tools.
Examine a PDF for hidden content
Use the Examine Document feature to find and remove content from a document that you don’t want, such as hidden
text, metadata, comments, and attachments.
If you want to examine every PDF for hidden content before you close it or send it in email, specify that option in the
Documents preferences using the Preferences dialog box.
1 Choose Document > Examine Document.
If items are found, they are listed in the Examine Document panel with a selected check box beside each item.
