How to Fix Acrobat Mobile Commenting Blocked by PDF Security Settings
Question details
Users are unable to add comments or highlights to password-protected or restricted PDFs using the Acrobat mobile app, even when commenting permissions are allowed.
- Product
- Adobe Acrobat Mobile
- Device & OS
- iOS and Android
- Scenario
- Attempting to annotate or leave comments on a secured PDF file using a mobile device like an iPad or Android tablet.
- Observed behavior
- The Acrobat mobile app reports that commenting tools are unavailable due to the document's security settings, whereas the exact same file allows commenting when opened in the desktop version of Acrobat.
Ensure your mobile Acrobat application is updated to the most recent version, and verify that you have the document's permissions password if you need to alter its security settings.
Sign in with a Paid Acrobat Pro Subscription
Premium editing and commenting features on restricted PDFs often require an active paid subscription to unlock on mobile apps.
While basic PDF viewing is free on the Acrobat mobile app, interacting with secured documents or accessing advanced annotation tools may be restricted unless you verify a paid license.
Open the Adobe Acrobat Reader application on your iPad or Android tablet before attempting to open the secured document.
Tap the profile icon in the top right corner and sign in using the Adobe ID associated with your paid Acrobat Pro subscription.
Open the secured PDF and select the commenting tools to check if the premium editing features have been successfully unlocked.
Remove Document Security Settings via Desktop
By stripping the security restrictions from the PDF on a desktop computer, you can allow the mobile app to process the file without blocking tools.
Use an Alternative Mobile PDF Reader
Many third-party PDF readers handle document security differently and may allow you to add and save comments where Acrobat mobile fails.

Frequently Asked Questions
Why does PDF commenting work on my desktop but not on my iPad?
Desktop PDF applications generally have more comprehensive support for parsing document security permissions. Mobile apps often take a stricter approach or lack the full protocol support, defaulting to restricting editing tools on protected files.
Do I need a paid subscription to comment on PDFs in the Acrobat app?
While viewing PDFs is free, interacting with certain secured files or accessing advanced annotation tools in the Adobe Acrobat mobile app may require you to sign in with an active, paid Acrobat Pro subscription.
How can I check the exact security settings of my PDF?
Open the PDF file using a desktop PDF reader, navigate to File > Document Properties, and look under the Security tab. This menu will detail exactly which actions, such as commenting or printing, are allowed or restricted.
Can free PDF readers bypass these mobile commenting restrictions?
Yes. Depending on how the security protocol was originally applied, alternative third-party mobile PDF readers often allow users to comment on and save protected files even if the official Acrobat app restricts those tools.
