What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Unfortunately, when you import a PDF form in JotForm, it cannot be edited. You can only re-download it and use to auto collect data or responses. Here's an example of PDF form that I imported in my JotForm.
You'll see that there are quite a few options on it compare to the online form.
I would advise recreating the PDF form in our form builder, that would give you a lot of options on how to use it. You can also convert that JotForm to a fillable PDF form.
I hope that helps. Do let us know if you need more information on this.
