How It Works
Upload a PDF that contains fillable form fields. The tool automatically detects all interactive fields — text inputs, checkboxes, dropdowns, and radio buttons — and presents them as an editable form.
Fill in the fields, then download the completed PDF. The form is "flattened," meaning the filled values become permanent text — the PDF will display correctly in any reader.
