- Product
- PDF Editor
- Device & OS
- not provided
- Scenario
- Attempting to permanently obscure confidential information in a PDF document.
- Observed behavior
- Applying the redaction removes all document content instead of just the selected text, a problem often noticed after upgrading Adobe applications.
Before making permanent changes or reinstalling software, test the redaction process on a duplicate or completely different PDF file to determine if the issue is file-specific or system-wide.
Test Redaction on a Different PDF Document
Determine whether the redaction error is caused by document corruption or a system-wide application glitch.
Often, a specific PDF may contain corrupted fonts, broken structural tags, or unsupported elements that cause the entire page's text layer to collapse when a redaction is applied.
Open a completely different, standard PDF file in your PDF editor.
Use the redaction tool to mark a small block of text for removal.
Click 'Apply' to permanently execute the redaction, and check if the surrounding text remains intact. If it does, the original document is the problem.

Update or Repair Your PDF Software
If redaction fails on all files, the application installation might be corrupted, especially common after recent software updates.
Ensure Proper Redaction Tools Are Used
Avoid using basic drawing shapes like black rectangles, as they do not securely redact text and can cause display rendering issues.
Safely Redact PDFs with WPS Office
WPS Office provides a dedicated, reliable PDF Redaction tool that permanently removes sensitive information without corrupting your document format. It securely deletes the underlying text and metadata while keeping the rest of your document intact.
- 1. Open your PDF: Launch WPS Office and open the PDF document containing sensitive information.
- 2. Access the Protect tab: Navigate to the 'Protect' tab on the top ribbon and select the 'Redact' tool.
- 3. Apply the redaction: Select the text or area you want to hide, then click apply to permanently and securely remove the data.

Frequently Asked Questions
Why shouldn't I just draw a black box over sensitive text?
Drawing a black rectangle using comment or shape tools only covers the text visually. Anyone viewing the PDF can easily drag the shape away, delete it, or highlight and copy the underlying text. True redaction tools permanently delete the text data and metadata from the file.
Can I undo a redaction after saving the PDF?
No. Once a redaction is applied and the PDF document is saved, the action is permanent. The original text is entirely deleted from the document's code, which is why you should always keep a backup copy of your original unredacted file.
Why did my PDF text disappear after updating Adobe Acrobat?
Software updates can occasionally cause plugin conflicts, display rendering bugs, or installation corruption that affects the redaction tool. Running a repair installation from the Help menu or reinstalling the application usually resolves this issue.
What happens to the document metadata when I use a proper redaction tool?
Professional redaction tools also scan for and allow you to remove hidden metadata, hidden text, and overlapping objects. This ensures that the confidential information cannot be recovered using advanced software or search functions.
