    It seems that the 'Copying of contents for accessibility' restriction when locking the pdf is not working correctly in PDF24 Toolbox version 11.29.1 and 11.28.2 The current online version of PDF24 Toolbox seems to work fine.

    Below is a screenshot showing how a file with all permissions removed presents itself in Acrobat Reader 2025.001.21111.

    Moreover, it seems that between version 11.28.2 and 11.29.1 the option to disable copying for accessibility was removed from PDF24 File Tools (dialogs available through right click on a PDF file), and is present only in the PDF24 Toolbox (though, it is currently not working correctly, as stated above).

    I am unable to post a link to the screenshot nor paste the image and my edits of the original message containing the link as well as a reply with the link are all missing.

    Hopefully you can see the screenshot here: pasteboard dot co slash hdszhRBPJayT.png

    Perhaps one further detail to mention is that I am not applying any password to the file that I'm trying to protect.

    I also noticed some further differences:

    • Online PDF24 Toolbox: generates AES-128 encrypted file with all restrictions set correctly (but no option to configure encryption type, nor a permission password field is present)
    • Offline PDF24 Toolbox: generates AES-256 encrypted file but accessibility copying for flag is not disabled (no option to configure encryption type is present but fields for both open and permission password are present)
    • Offline PDF24 File Tools: no checkbox to configure accessibility copying flag present
      • When using AES-256 or AES-128, the result is effectively the same as for offline PDF24 Toolbox
      • When using RC4-128, the accessibility copying shown in Acrobat Reader is allowed under the 'Document Restriction Summary' section of 'Document Properties', but in the dialog 'Document Security' ('Document Properties'>'Security'>'Show Details..."), 'Content Accessibility Enabled' is not allowed (this seems inconsistent, not sure if this is a bug in Acrobat Reader?)
