There are several reasons to avoid creating a fillable form in either PDF or Word. The primary issue is that both of these form types require apps to be installed on your form takers' device.
Another reason to use a dedicated online form creator is that if you need to update your form by correcting typos, adding or removing questions, you do not need to redistribute your form to all your participants.
Online form creators show start and finish completion rates, have significantly higher completion rates, and can be completed on all phones, tablets, and PCs without additional software.
Create a form using a free online form maker like the one above, Google Forms, JotForm or Typeform, and others.
Simply add questions and generate a link to share directly with your form participants.
