Tips & Best Practices
Understand the Scope
This tool primarily finds top-level "Document Actions" JavaScript. Scripts can also be hidden in other places like annotations or form fields, which may not be detected by this initial scan.
Sanitize if Unsure
If you find unexpected JavaScript and you don't want it, the safest action is to use our "Sanitize PDF" tool to remove all scripts from the document.
