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 a PDF tool to remove or redact sensitive images and text visible in a PDF.
Redaction is permanently removing visible text and graphics from a document. You use the Redact a PDF tool to remove content. In place of the removed items, you can have redaction marks that appear as colored boxes or leave the area blank. You can specify custom text or redaction codes to appear over the redaction marks.
(Optional) To repeat a redaction mark, right-click it and choose Repeat mark across pages. This feature is convenient if a particular header, footer, or watermark appears in the same location on many pages.
Files of any format can be attached to the PDF as an attachment. To view attachments, choose View > Show/Hide > Side panels > Attachments (macOS), or hamburger menu > View > Show/Hide > Side panels > Attachments (Windows).
This item includes Form Fields (including Signature fields) and all Actions and calculations associated with form fields. If you remove this item, all form fields are flattened and can no longer be filled out, edited, or signed.
PDFs can contain multiple layers that can be shown or hidden. Removing hidden layers removes these layers from the PDF and flattens the remaining layers into a single layer. To view layers, choose View > Show/Hide > Side Panels > Layers (macOS) or hamburger menu > View > Show/Hide > Side panels > Layers (Windows).
An embedded search index speeds up searches in the PDF file. To determine if the PDF contains a search index, go to Acrobat All Tools > Add search index and select Manage embedded index in the left pane. Removing indexes decreases file size but increases search time for the PDF.
By default, thin red outlines appear aroundimages and text you mark for redaction, and black boxes appear inplace of redacted images and text. You can set the default appearanceof redaction marks before you mark items for redaction. You canalso change the look of redaction marks before you apply the redactions.
Fills the redacted area with as many instances of the custom text as needed, without changing the font size. For example, if you specify the letter x or a hyphen (-) as the custom text, these characters are repeated throughout the redacted area.
Acrobat uses overlay text to overprint areas selected for redaction. One example of overlay text is a redaction code, which consists of one or more code entries from a code set. Acrobat includes the U.S. FOIA and U.S. Privacy Act code sets that you can use. You can use either codes or custom text to create overlay text. The difference is that redaction codes are text entries that you can save, export, and import. One code set can contain multiple codes.
Select a Code Set from the list at the bottom of the context menu, and then select a code entry from the drop-down menu. A check mark appears next to the code entry when the code is applied.
To apply the same code to multiple redactions, set the redaction properties before you mark the content. In the secondary toolbar, click Properties. Select Use Overlay Text, then select Redaction Code. Select a Code Set and a code entry, then click Add Selected Entry.
If you learn how to redact a PDF, you can easily black out credit card numbers, social security numbers, addresses, and other personal details in forms you share electronically. Concealing sensitive information is especially helpful to ensure safe communication between businesses and customers, medical providers and insurance companies, schools and students, and, of course, law firms and courts.
In addition to text and images, PDFs contain data about the information within, or metadata. Metadata can include the document's author, the document description, keywords, and dates and times of creation or modification. A PDF might also contain elements like JavaScript that can change and unexpectedly modify the formatting. All of this is info you might want to keep private. By removing it through PDF redaction, you can ensure your PDF is safe and your formatting is consistent.
5. In the same pop-up window, select whether you want to remove the hidden data and metadata as well. Sanitize the PDF by leaving the toggle button on. (Read more about sanitizing documents below.)
For example, US courts require that mentions of Social Security numbers, names of minor children, dates of birth, and financial account numbers be redacted in legal filings. You can make quick work of these redactions with the Find Text tool in PDFs that contain searchable text.
The removed information might include metadata, embedded content, attached files, scripts, hidden layers, embedded search indexes, stored form data, comments and annotations, hidden data from previous document saves, obscured text and images, unreferenced data, links, actions, JavaScript, and overlapping objects.
You may be most familiar with redaction in legal or government-related documents. When court documents are published or shared with other parties, sensitive or private information is redacted. This includes information that could pose identity theft risks, information relevant to ongoing investigations, classified information, and information deemed otherwise unnecessary and too private for the public. Courts specifically mandate that certain personally identifiable information (PII) be redacted, so redaction is used especially often in legal settings. Sensitive or identifying images might also be redacted, sometimes including just faces in images.
Besides being useful in legal settings, people might want to learn how to redact a PDF to protect similarly sensitive information in professional communications between businesses or clients. Businesses can protect trade secrets and proprietary information when sharing documents. Certain financial information may also be kept secure by redacting it in a PDF.
In the medical field, PHI (Private Health Information) may need to be redacted to comply with laws like HIPAA. Because HIPAA requires clients to be informed when their PHI is shared illegally, privacy is especially important, and PDF redaction can be a useful tool to ensure security.
Some methods of redaction, such as changing the font color to white or using a black marker on physical documents, are unreliable and may not secure the information you need to keep private. Using a PDF redactor, on the other hand, is a secure method many industries rely on.
Hi
We are having problems with redaction.
We are using a discovery tool and have exported some documents thet need redaction.
We are using Adobe Acrobat Pro (9.3 I think).
We are unable to use the redaction tool on these documents.
We are able to redact documents printed from within Microsoft Word (print to Adobe PDF)
Even if I open and print the exported documents to Adobe PDF thee redaction will not work?
Any ideas?
All help is greatly appreciated
I am using the redaction tool in DC which I have used many times. I hit redact. Text and Images, Highlight what I want redacted and hit apply. It is redacting what I highlighted but also highlight the first letter and last of most of the other sentences on the document I did not select.
At the moment, I select the items I want to redact (text like 123 234 345 - that is, numbers with spaces - but the same numbers) and it does redact them, but redacts other numbers too! Should I try "123 345 456" - or something? only want to redact these numeric sequences.
I am having a similar problem. When I redact information on one page, black rectangles show up in the same area on the other pages of my document. I have a large image that takes up most of my document's second page. When I drag and redact it, the preview looks completely normal. However, after I apply the redaction, there is a large black rectangle on all three pages of my document.
I am having a similar problem. It seems that if I find and mark text for redaction it displays perfectly, but when I apply it also redacts all of the 'hidden information'. But I have not selected the hidden info for redaction.
My office is also having major problems with this. Now that Marsy's Law is in effect, we have to redact soooo much information from our police reports. These come from many different agencies using different software to create their PDFs. It's ridiculous that it is happening so frequently across so many different agencies' PDFs. The only thing I have found to get around it is to remove just Objects from the Remove Hidden Information section and re-run text recognition on the file. It noticeably diminshes the quality of text in the PDF. Adobe needs to fix this.
I have the same problem. I have tried multiple documents and the same problem appears with every document, also have checked that the documents are not secured. I also disabled the settings in phase 2, but it has not solved the problem.
I have the same problem, along with the fact that Acrbat Pro DC freezes at random and frequently. The only way to close the program is through Task Manager. I really miss my Arobat Pro XI. It was supposed to have a perpetual license. I guess the end of the world happened and I missed it because when Adobe stopped supporting XI, it stopped working after the first Windows 10 update. Software companies make enough money. They should let you choose to purchase a program instead of having to pay by the month for the rest of your productive life, which won't be very productive if using products like Acrobat Pro DC. I have read and tried more fixes than I can count and the app is still near worthless.
I also am having many problems with redaction. Many of the items I am trying to redact are not found. I try various subsets of the text string and sometimes they work and sometimes not. It would be far easier at this point to print, mark out with a market pen, and scan.
