A: No! Only the hidden metadata dictionary and XMP packets are cleaned; all text, images, vector graphics, and layouts remain 100% intact.
Q: Is my document uploaded during sanitization?
A: No! All metadata stripping is performed locally inside your web browser sandbox with zero network transmission.
