How do I add a fillable PDF form to my web page?

Please allow me to inform you that Fillable PDFs are intended for offline use. It allows your users to download and fill in the form offline and then submit it once they are at a place with an internet connection.

If you want to add a form to your webpage, I would recommend adding the web form instead. Web forms are specifically designed for online use, and they are mobile responsive so your users can still fill your form while browsing your web page on their mobile devices. You can also use widgets and payment fields with the web version of the form. To add a form to your webpage, please follow our guide here: Adding a form to a web page.

If you need further assistance, please let us know.
