Frequently asked questions
My PDF shows no blue boxes. Why?
The PDF has no fillable fields — it is just a printed form. Use Edit PDF and its "Add text" tool to type anywhere on the page.
What does "lock the answers" (flatten) do?
It turns your answers into normal page content, so the form can't be edited again. Some offices ask for flattened forms.
Can I type in Hindi or other languages?
Yes. A font that supports many languages is added automatically when needed.
Is it really free? Do you add a watermark?
Yes, it is completely free with no sign-up, no watermark and no daily limits. The site is supported by a few non-intrusive ads.
