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.
I understand that you want to resize the form to fit on one page. You may try reducing the line spacing and vertical padding from the Line layout section of Form Designer.
However, this depends on the number of the fields added to the form that fits one page. Please give it a try and let us know if you need any further assistance. We will be happy to assist.
