Frequently asked questions

How do I fill out a PDF form for free?

Upload a PDF that has interactive form fields, type your answers into the fields shown, then download the completed PDF. It happens entirely in your browser.

My PDF has no fillable fields, what now?

If a form is flat (no interactive fields), use the Edit PDF or Fill & Sign tool to add text on top of the page instead.

Can I lock the form after filling it?

Yes. Filled values are saved into the file. To make them non-editable, run the Flatten PDF tool afterward.

Is my data private?

Yes. Form filling runs in your browser, so your answers and file never leave your device.

Is it free?

Yes, free with no watermark and no sign-up.
