How does the Fill PDF Form work?
Fill in the blanks of an AcroForm PDF — the kind of fillable form government agencies, HR departments, and banks distribute. Drop the PDF, leave the values blank on the first run to discover the field names, then come back with `name=value` lines (one per line) to fill them. Supports text fields, checkboxes (true/false), dropdowns, and radio groups. The output is a real PDF with the values written in — open it in any reader to verify, then print, sign, or send. The whole process runs in your browser; we never see the form contents.
