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 it is an Adobe FormsCetral PDF form, you can import it using our tool: https://www.jotform.com/help/340-How-to-Import-Adobe-FormsCentral-PDF-Forms-to-JotForm
However, no more edits can be done to it, since it's not going to be a web-form. So, it might be easier to start your a web-form from the scratch and then export it to a fillable PDF form: https://www.jotform.com/help/212-How-to-create-a-PDF-form
Let us know if you have more questions, we will be glad to assist you.
