Question details
The user is trying to find and use the redaction tool to hide sensitive information in a PDF document using the Adobe Acrobat mobile app.
- Product
- Adobe Acrobat Mobile App
- Device & OS
- Android / iOS
- Scenario
- Editing a PDF file on a mobile device to permanently remove or blackout sensitive text and exhibits.
- Observed behavior
- The redaction tool is missing from the mobile app interface despite the user having purchased an Adobe Premium mobile subscription.
Verify your current Adobe subscription plan through your account settings, as the redaction feature requires an active Acrobat Pro plan rather than the basic Reader Premium tier.
Access Redaction with an Acrobat Pro Subscription
If you are an Adobe Acrobat Pro subscriber, you can unlock premium tools like redaction in the free mobile app by signing in with the correct Adobe ID.
The standard Adobe Reader app does not include redaction capabilities natively. This feature is unlocked dynamically when the app detects a valid Acrobat Pro subscription tied to your account.
Launch the Adobe Acrobat app on your mobile device and tap the profile icon in the top right corner.
Tap 'Sign In' and enter the Adobe ID email and password specifically associated with your Adobe Acrobat Pro subscription.
Return to the main screen, open your PDF document, and tap the 'Edit' floating action button at the bottom right to locate and use the 'Redact' tool.

Redact Sensitive Information via the Web
If your mobile setup is insufficient, you can use the web version of Adobe Acrobat on a supported desktop platform to process your files securely.
Edit and Protect PDFs Effectively with WPS Office
Need a fast, cost-effective way to handle sensitive PDF documents on your mobile device or computer? WPS Office offers a comprehensive PDF editor that allows you to securely delete text, modify content, and encrypt your files without requiring expensive premium subscriptions.
- 1. Open the PDF in WPS Office: Launch the WPS Office mobile or desktop app, tap 'Open', and select your PDF document from your local storage or cloud drive.
- 2. Remove Sensitive Text: Tap the 'Tools' menu, navigate to the 'Edit' tab, and select 'Edit Text'. You can now select any sensitive text blocks and delete them entirely from the document.
- 3. Encrypt the File: To add an extra layer of security, go to the 'Protect' tab (or the 'File' menu on desktop) and select 'Encrypt' to require a password for opening the file.
- 4. Save as a New Document: Tap 'Save As' to export your changes into a new, secure PDF file, ensuring the sensitive information is stripped from the final version.

Frequently Asked Questions
Why is the redaction tool completely missing from my Adobe Reader app?
The redaction tool is restricted to Adobe Acrobat Pro subscribers. If you are using the free version of Acrobat Reader or only have the basic Adobe Premium Mobile subscription, the feature is hidden from your tool menus by default.
Is deleting text in a PDF the same as redacting it?
Not exactly. True redaction securely scrambles and removes the underlying text data and metadata so it cannot be recovered. However, manually deleting text using a PDF Editor like WPS Office also permanently removes the text characters from the document, achieving a similar goal of hiding sensitive data.
Can I upgrade to Acrobat Pro directly inside the mobile app?
Yes, you can typically upgrade your subscription tier via the app's settings menu or through your Adobe account dashboard online to unlock Pro features like redaction across all your devices.
