How OpenFileTools processes it
Local processing, explicit choices.
The browser inspects AcroForm dictionaries, updates only editable supplied values, regenerates appearances, saves a separate PDF, reopens it, and verifies values, widgets, page geometry, and appearance streams.
Questions, answered.
Is the form uploaded?
No. PDF bytes and entered values stay in this browser tab.
Does this support XFA?
No. XFA is detected and clearly blocked because reliable editing requires a different form engine.
Can I add a digital signature?
No. Existing signature fields are preserved but this tool does not create cryptographic signatures.
