What if my PDF has no form fields?

Then there's nothing to type into. For a flat PDF (a scan or a form without interactive fields), use Edit PDF to add text boxes anywhere on the page instead.

Can I lock my answers in?

Yes. Turn on Flatten so the filled values become permanent page content that can't be changed after you download.

How it works

How to fill a PDF form without uploading it

Drop a PDF with interactive fields and FernPDF lists every text box, checkbox and dropdown for you to fill. Complete the form and download it, optionally flattened so the answers are locked in.

Because filling happens in your browser, applications, tax forms and contracts with personal details are completed without ever being uploaded.
