How this works
When you upload a PDF, this tool reads its built-in form fields and lists them for you to fill in directly. Once you save, your answers are written into the same fields inside the PDF, so the completed form looks exactly like it was filled in a PDF reader.
Frequently asked questions
What if no fields are detected?
Not all PDFs contain real form fields — some forms are just printed lines meant to be filled by hand or with a PDF editor. If no fields show up, the document likely doesn't have fillable fields built in.
Can I fill checkboxes and dropdowns, not just text?
Yes — this tool detects checkboxes as well as text fields and presents the right input type for each.
