Does this work on any PDF?
It works on PDFs that already contain fillable AcroForm fields. A plain scanned document with no form fields can't be filled this way.
Can I lock the answers in afterward?
Yes, use Flatten PDF after filling to make the entered values permanent and non-editable.
Is my file uploaded anywhere?
No, the form is filled entirely in your browser.
