Fix: Redact Tool Not Available in Adobe Acrobat Mobile App
Question details
Users are unable to locate or use the Redact tool in the Adobe Acrobat mobile application, despite having an active Adobe Acrobat Pro subscription.

- Product
- Adobe Acrobat Mobile App
- Device & OS
- iPhone
- Scenario
- Attempting to permanently obscure and remove sensitive information from a PDF file using a mobile device.
- Observed behavior
- The Redact tool does not appear in the mobile app interface and cannot be enabled by signing into a Pro account, as the feature is currently unsupported on mobile.
Ensure you have access to a desktop or laptop computer, as safely and permanently redacting PDF content typically requires desktop-grade PDF editing software.
Use Adobe Acrobat Pro on a Desktop Computer
Because Adobe does not support the Redact tool on mobile devices, you must transfer your PDF to a computer and use the desktop version of Acrobat Pro.
True PDF redaction permanently removes text, graphics, and underlying metadata from the document code. Due to the complexity of this process, Adobe restricts the Redact tool entirely to its desktop applications. Signing out and signing back into your Acrobat Pro account on your iPhone will not unlock this tool.
Save the PDF from your iPhone to a cloud storage service like Adobe Document Cloud, iCloud, or Google Drive, then download it onto your Windows or Mac computer.
Launch the Adobe Acrobat Pro desktop application and open your downloaded PDF file.
Click on the 'Tools' tab at the top left of the screen, scroll down to the 'Protect & Standardize' section, and select 'Redact'.
Choose 'Mark for Redaction', highlight the sensitive text or images you wish to hide, and click 'Apply'. Save the file as a new copy.

Securely Edit and Manage PDFs with WPS Office
Looking for a cost-effective and highly versatile PDF editor? WPS Office provides a comprehensive suite of PDF tools that let you easily manipulate text, hide sensitive information, and manage your documents directly from a lightweight application.
- 1. Download and Install WPS Office: Get the free WPS Office application on your computer and open the PDF containing sensitive information.
- 2. Access the Edit Tab: Navigate to the 'Edit' tab located on the top ribbon to reveal the comprehensive list of PDF modification tools.
- 3. Obscure the Content: Use the shape tools to draw a solid black rectangle over the sensitive information, ensuring the text behind it is visually covered.
- 4. Flatten and Save the PDF: To prevent others from moving the shape and reading the text underneath, use the 'Print' function and select 'Print to PDF' or export the document as a flattened image PDF.

Frequently Asked Questions
Why is the redact tool not included in the Acrobat mobile app?
Adobe has not integrated the Redact tool into its mobile applications because proper redaction requires permanently deleting underlying document code and metadata. Adobe currently limits these advanced security features to its desktop software.
Can I hide text on my iPhone by drawing a black box over it?
Drawing a black box over text using markup tools visually hides the information, but it does not permanently remove it. Anyone who receives the file can easily delete the box or copy the underlying text. True redaction requires specialized desktop tools.
Will upgrading my subscription fix the missing tool issue?
No. The absence of the Redact tool is an intentional limitation of the Acrobat mobile app's design. It will remain unavailable on your iPhone regardless of whether you have an active premium or Pro subscription.
How can I tell if my document has been properly redacted?
A properly redacted PDF will not allow you to highlight, select, or copy the blacked-out text. If you can still drag your cursor over the black box and paste the text into a Word document, the text has only been covered, not redacted.
