- Fill in the form on this page.

02 Good to know
Values are written into the PDF's own form fields, so they stay editable unless you lock them.
03How to fill an interactive PDF form
Choose a PDF with interactive form fields. Enter text, select checkboxes or radio buttons, and choose values from dropdowns in the form viewer.
This tool fills fields already present in the document. A flat scan or a PDF with blank lines but no form fields needs text added with a PDF editor instead.
04Save editable or locked answers
By default, answers stay in the PDF's form fields and can be changed later in a compatible reader. Turn on Lock answers to flatten the fields into page content when you are ready to submit a fixed copy.
Review the downloaded file, especially dates, totals and selected options. Keep an unfilled original for future use.
05Check compatibility
PDF forms vary in how their fields and appearances are built. If a field does not display or save as expected, try another PDF reader and verify the output before sending it.
06 Questions
Can I fill a scanned form with this tool?
Only if the PDF contains interactive fields. A scan with printed blanks needs text placed on the page with a PDF editing tool.
Can I keep the answers editable?
Yes. Leave Lock answers turned off. Turn it on to flatten the answers into the page.
Can I add a signature here?
This tool fills existing form fields. Use the signature tool to place a visible signature mark.
