File upload field from form does not show on the PDF form?

Hi there, the form I created has a file upload button - when creating a PDF from the form, the file upload / attachment function is missing.

Please advise Thanks

I presume when you say PDF Form it's the converted fillable PDF version of the online form, is that correct? To learn more about this features including its limitations, please check this guide: https://www.jotform.com/help/312-JotForm-Fillable-PDF-Creator-With-All-Points 

There are a couple of features that will not work on the PDF form, example is the File Upload field, I have quoted it here for your reference:

"The File Upload (9) field is hidden at this time on the PDF files since you can’t transfer file attachments to our servers via a PDF."

It is not possible to run the file upload scripts on a PDF reader. 

I hope that helps. Let us know if I misunderstood your concern.
