Can I upload a pdf?

I'm sorry, but I need to clarify whether you are trying to upload and display a PDF file in your form or if you are asking how people can upload a PDF in a file upload field of your form once they view it.

To display a PDF in your form, please follow the steps here: https://www.jotform.com/help/153-How-to-Display-a-PDF-Document-On-Your-Form. 

To allow PDF uploads in the form, add a file upload field in your form. Please read the guide here: https://www.jotform.com/help/332-How-to-Create-File-Upload-Forms.
