Try the example
Fictional file created by SunPDF with no personal data.
Disallow copying, printing and editing, export the copy, then inspect the permissions reported by your PDF reader.
What does this PDF tool do?
Enable only the intended uses. A random owner password protects the settings without being shown or stored. The PDF opens without an opening password and keeps accessibility extraction available for assistive technology.
Document processing happens in your browser. SunPDF does not upload your PDF to a server for editing. Closing or refreshing the tab ends the current session.
When to use this tool
These restrictions are a useful guardrail for a reading copy that should not normally be printed, copied or edited.
How to check the result
Test the copy in the intended readers, inspect the reported permissions, and confirm assistive access still works.
