JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
You can import from external files, however, please note that this will not 100% copy your forms especially the styles and other fields that do not match the structure that we have. You can use this app: https://apps.jotform.com/app/spread2jot
You should also be able to import the fillable PDF form in your JotForm account, BUT you cannot edit it in our form builder. What happens is that it will allow you to collect data from that fillable PDF form when your users fill it out and click the submit button. You can check this page for more information: http://www.jotform.com/fillable-pdf-form-creator/
I hope that helps.
