How to remove and redact sensitive information from PDF files

Lisa Croft – September 7, 2012

Acrobat XI Pro lets you quickly remove hidden information from a PDF so that you can distribute your file knowing that that your confidential data doesn't get revealed to others. This is done using redaction tools. Within Acrobat, I'll just select tools, then protection, then mark for redaction. And I'll walk through the document selecting the text or image information that I want to remove. I can also select search and remove text to automatically find and redact words, such as repeating text or patterns, like email addresses. I'll click search and remove, select the information that I want to remove and mark those for redaction as well. When I'm finished, I'll click apply redactions and my visible content is permanently removed. But what about that information that's not easily visible, like document properties, attachments or stored form data? Acrobat XI Pro will prompt me to remove that hidden information. Acrobat will scan through the document and allow me to review what's been identified. When you're ready, select remove and you're done. The visible and invisible sensitive information has been permanently deleted. With Acrobat XI Pro, you can easily redact and sanitize files so you can distribute them with confidence.

Hi Fred,

This tutorial is for Acrobat XI. In this version the Redaction feature has been modified so that it’s easier to walk through the process. In addition, you’ll find an Action Wizard in the Pro. version to simply things.

Thanks,
Lori

Really? Acrobat 9 - Is it that difficult to show simple text instruction for such a simple feature. I found it simpler to go back to the source Word doc and edit that and reconvert it to PDF. ADOBE - why make redaction so darn difficult!!!!!!!!!! Your help files are also useless and your search feature is worthless.
