Would the jotform format get affected once I edit the layout of the pdf form?

Another question is, would the jotform format get affected once I edit the layout of the pdf form? I have noticed that it changed my form upon adding some elements to it.

Hi, that is correct, design changes that you apply to the PDF form will affect the web form. If you don't want that to happen, you may clone your web form, and use the clone version just to create, modify, and download the PDF version: https://www.jotform.com/help/27-How-to-Clone-an-Existing-Form-from-Your-Account

Thanks for the tip! I will do that.
