Why Remove JavaScript from an Untrusted PDF?

Frequently Asked Questions

Why sanitize a PDF before opening it?
If the file came from an untrusted source, removing embedded JavaScript reduces one common attack vector before the document is opened or redistributed.
Will this break legitimate form logic?
It can. If the PDF relies on JavaScript for calculations or dynamic validation, those script-driven features will stop working after removal.
Is this the same as full PDF sanitization?
No. This use case targets JavaScript specifically. A full sanitization workflow can also remove metadata, links, and other embedded elements.
