Frequently asked questions
How to fill a PDF form for free?
Upload the PDF, click on the fields and type your answers, then download the filled form. Filling PDFs is free, no sign-up required, and done entirely in the browser.
Can I fill a PDF that doesn't have form fields?
Yes. You can add text boxes on top of the PDF to fill documents that don't have ready fields. Since everything runs in the browser, nothing is sent to a server.
Is filling PDFs online safe?
It's safe: the document stays only on your computer, as the filling happens locally in the browser. This way you fill out forms and contracts with personal data for free and without registration.
