Fix PDF Becomes Read-Only in Acrobat Reader on iPad
Question details
The user needs to regain editing access to a PDF document that was previously editable but has unexpectedly become read-only.

- Product
- Adobe Acrobat Reader Mobile
- Device & OS
- iPadOS
- Scenario
- Attempting to modify or annotate a PDF file on an iPad using the Acrobat Reader mobile app.
- Observed behavior
- The PDF file is locked in read-only mode, preventing the user from making any edits, often occurring after a month of normal usage.
Verify that your iPadOS is updated to the latest version and ensure you are running the most recent update of Acrobat Reader Mobile from the App Store.
Verify Subscription Status and Document Restrictions
Check if your premium editing trial has expired and ensure the PDF itself does not have author-applied editing restrictions.
Acrobat Reader requires an active premium subscription to edit PDFs. If you were using a free trial, your editing capabilities will revert to read-only once the trial period ends.
Open Acrobat Reader Mobile on your iPad. Tap on your 'Profile' icon and navigate to 'Subscriptions' or 'About Acrobat Reader Mobile' to confirm your premium plan is active.
Open the affected PDF document. Tap the three-dot menu and select 'Properties' or 'Security' to see if the file author has restricted editing privileges.
Move the PDF to the iPad's Internal Storage
Transfer the file from cloud drives or external storage to the local iPad storage to bypass restrictive file-change permissions.
Use WPS Office for Easy PDF Editing on iPad
If you are struggling with expired trials or read-only lockouts in other apps, WPS Office provides a robust, built-in PDF editor. Easily modify text, add annotations, and manage your documents without dealing with complex permission errors.
- 1. Download WPS Office: Search for WPS Office in the App Store and install it on your iPad.
- 2. Import the PDF: Open WPS Office, tap the '+' or 'Files' tab, and open your PDF document from local or cloud storage.
- 3. Start Editing: Tap the 'Edit' tool at the top of the screen to unlock text boxes, add shapes, or insert digital signatures instantly.

Frequently Asked Questions
Why did my PDF suddenly become read-only after a month?
This commonly occurs when a free trial for premium PDF editing features (usually lasting 7 to 30 days) expires. Once the trial ends, the application reverts to a free basic viewer, which only allows you to read files, making them appear locked or read-only.
Can cloud storage cause a PDF to be read-only on my iPad?
Yes. Third-party cloud storage providers like Google Drive or Dropbox can sometimes restrict file write permissions when accessed through external PDF apps. Moving the file to your iPad's local storage ('On My iPad') usually restores editing capabilities.
How do I check if my PDF has a password or editing restriction?
Open the PDF in your reader app and look for a padlock icon, or navigate to the document's properties/security settings. If the author applied restrictions, you will need the permissions password to unlock the document for editing.
