is there a way to prevent editing the file after exporting

First of all, thank you for this great tool!

I’m using it to add a stamp or signature to a PDF file, and then export it. However, I noticed that after exporting, if someone opens the file in Adobe Reader, they can still move, delete, or edit the stamp or signature.

Is there a way to finalize or flatten the PDF upon export, so that these elements become a permanent, non-editable part of the PDF content? Ideally, I’d like the exported PDF to be treated as a final version that does not allow any modifications to the annotations.

Thanks again for your work on this tool, and I appreciate any guidance or suggestions!

OK, I originally only tested with WPS and didn’t notice the issue. When I used Acrobat, the problem did appear.
I have now enabled the "lock" mode for the SIGNATURE and STAMP fields. This will prevent them from being edited when opened in editing software, which should achieve the effect you mentioned.
