More details

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. JavaScripts, 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.

This item indicates text in the PDF that is either transparent, covered up by other content, or the same color as the background. To view hidden text, click Preview. Click the double-arrow buttons to navigate pages that contain hidden text, and select options to show hidden text, visible text, or both.
