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 are trying to download the form to a fillable PDF and the PDF generated is not looking good. I have checked your JotForm and see that there are several images with matrix fields. Unfortunately, we have some limitation to process the form to a fillable PDF particularly with some fields like Header, Text field and Images. Our development team is working on to improve this feature. Please refer to the guide below that can help you with more information on the Fillable PDF creator.
Hope this information helps!
