Fill out a PDF form online

How to Fill out a PDF form

1

Add the form

Click “Select file” or drag and drop any PDF form — flat and scanned forms included.

2

Type your answers

Click where an answer goes and type. Add check marks for checkboxes, and sign with the Sign tool.

3

Download the filled form

Click “Save”. Your answers are flattened into a standard PDF, ready to email or print.

Every step runs in your browser. No server uploads, no waiting.

Why use this tool

Bring any PDF form — a job application, a school form, a scanned government form — and type your answers straight onto it. Add check marks, then sign with the built-in signature tool. Download a filled, flattened PDF that opens anywhere. No account, no watermark, and the form itself never leaves your device. If the form is a scan and you also want its own text searchable, run OCR PDF first. For everything beyond forms — editing text, shapes, images — use Edit PDF.

When you'd use this

Job & rental applications

Fill an application you received as a PDF and send it back the same hour.

School and government forms

Type onto forms that were never made fillable — including scans.

Medical intake forms

Fill them at home; the form stays on your device.

Fill and sign a contract

Complete the blanks and sign, in one editor, in one pass.

Fill and sign in one place

Most forms end with a signature line. The same editor that fills your form carries DukPdf’s signature tool — type, draw, or upload your signature, place it on the line, and save once. No second tool, no second upload, no printer.

Fill PDF Form — questions

Does it work with scanned forms?

Yes — you type wherever you click, so a scanned or photographed form fills exactly like a digital one. If you also want the scan’s own text searchable, run OCR PDF first.

Does it work with fillable (interactive) PDF forms?

Yes — click into any field and type. Checkboxes, radio buttons and dropdowns work too. Forms without fields still fill by typing anywhere.

Can I fill and sign in one place?

Yes — the signature tool is built into the same editor. Fill the blanks, place your signature, save once.

Will the answers I type stay editable?

Until you save, yes. On save your answers are locked into the page by default; tick “Keep form fields editable” if the recipient still needs to change them.

Can I fill part of a form and finish later?

Yes — download the partly filled form, then open it again later and keep typing. Text you already saved becomes part of the page.
