Fill and Sign Not allowed.

 

I created a PDF on my PC. To prevent editing, I protected it with a password, but I'm allowed to fill out and sign it. 
I have PDF XChange Pro on my PC. On my iPad, I open this document with Adobe Acrobat Reader.
However, I'm only allowed to read the file and can't fill out or sign anything. It tells me that the document is write-protected. The 7-day trial version didn't help either.

Hi there,

 

Hope you are doing well and thanks for sharing the details.

 

The behavior you’re seeing is expected. Here’s why:

When a PDF is secured with certain permissions (like restricting editing), the non-Adobe desktop app you used (PDF XChange Pro) doesn't respect those restrictions and may still allow some interactions like filling or signing, but when you open the same file in Adobe Acrobat Reader on iPad, the app respects those restrictions more strictly. That’s why you can only view it and get the “write-protected” message.

 

Hope this information will help

Hallo Amal, ich habe es jetzt Noch mal getestet. Diesesmal habe ich zum
erstellen Adobe Acrobat Pro (testversion) am PC genutzt. Dennoch kann ich
am iPad es nicht bearbeiten. Der Bearbeitungsschutz wird auch jetzt
komplett ausgelegt und ich kann kein formularfeld füllen.

Gibt es noch einen Lösungsweg?

Mit freundlichen Grüßen
Robin

Hi @robin_9999,

 

Thanks for the response. 

 

As rightly mentioned by Amal, if there is any sort of protection on the document, Acrobat Reader for Mobile will not be able to make changes, fill form fields on it. 

This is a feature limitation.

 

Please feel free to share your feedback here: https://adobe.ly/4mx784c to ensure it reaches the development team for review and future implementation.


Regards,
Souvik.
