How does the Add Checkbox work?
Add AcroForm checkboxes to an existing PDF. Each checkbox line specifies position, size, internal field name, and the label drawn to the right of the box. Useful for terms-acceptance pages, opt-in confirmations, multi-select agreement forms, or annotation systems where the recipient should mark items they reviewed. The user ticks boxes in any PDF reader; values come back true/false through Extract Form Data to CSV.
