What can't Fill PDF Form do?

Text-field filling supported; exotic widget types / XFA forms are not. That limit is stated on the page and in the alert above the tool, not buried in a footnote.

Will it work on a phone?

Yes. The layout adapts to a small screen and the processing runs in the mobile browser, so a photo or a downloaded document can be handled on the device it arrived on.

Do I need to pay or register?

No. Every tool on this site is free, with no account, no email and nothing to install.

Which file types does Fill PDF Form accept?

The drop area takes PDF. Files are read from your device in the browser, so the format has to be one a browser can decode — that is why the accepted list on this page is finite and honest rather than "everything".
