Frequently asked questions
How do I list PDF form field names?
Drop the PDF here. Every AcroForm field appears with its name, type, and on-page position.
Why do some fields show no widgets?
Some PDFs define fields without on-page widgets, or use structures this viewer cannot map.
Which field types are detected?
Text, checkbox, radio, dropdown, option lists, and signature fields (AcroForm).
Is the form uploaded?
No. Inspection runs locally in your browser.
