- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Applying security redactions to a PDF document while trying to preserve specific metadata, alternate text, or other hidden structures.
- Observed behavior
- The software automatically performs a 'Finding Hidden Information' scan prior to redaction, flagging metadata, comments, and hidden objects for removal, which the user wishes to control or bypass entirely.
Before modifying redaction settings or sanitizing your document, ensure you save a backup copy of the original PDF so you do not permanently lose essential metadata or comments.
Review and Customize Hidden Information Scan Results
The safest and most reliable way to control this feature is to let the scan run and manually clear the specific categories of information you want to retain.
The Finding Hidden Information feature functions as a crucial security safeguard. It ensures that deleted or redacted text isn't inadvertently left recoverable in metadata, comments, attachments, or alternate text structures. Leaving hidden content unreviewed can accidentally expose the exact sensitive information you are trying to protect.
Open your PDF, mark the text or objects you wish to redact, and click the button to apply the redactions.
Allow the software to perform the 'Finding Hidden Information' scan automatically.
Look at the list of found items in the hidden information panel, which may include Metadata, Comments, Hidden Text, and Overlapping Objects.
Uncheck the specific categories or items that you do not want removed from the document.
Click 'Remove' or 'Apply' to finalize the redaction while preserving the unchecked metadata categories.
Disable Automatic Document Sanitization Prompts via Preferences
If you wish to stop the software from automatically prompting you to remove hidden information every time you apply redactions, you can disable this specific prompt in your settings.

Frequently Asked Questions
Why does my PDF editor search for hidden information during redaction?
This search acts as a critical security safeguard. Deleted or redacted text might still remain recoverable in document metadata, alternate text for images, comments, attachments, or overlapping objects. The scan prevents accidental leakage of this protected information.
Can I recover redacted text if I change my mind later?
No. Once redactions are applied and the document is saved, the information is permanently removed from the file. It is highly recommended to always keep an unredacted backup of your original file before applying changes.
What is considered 'hidden information' in a PDF document?
Hidden information typically includes document properties and metadata (like author names and creation dates), hidden text layers, user comments and markups, file attachments, bookmarks, and overlapping graphical objects that are not immediately visible to the reader.
How do I keep my PDF metadata while still redacting text?
When the hidden information scan appears before you finalize your redaction, simply review the scan results and uncheck the 'Metadata' or 'Document Properties' category. This allows you to apply the text redaction while preserving the author and date information.
