Can I edit an uploaded PDF form?

I'm seeing you have a separate thread here https://www.jotform.com/answers/936535 about uploading a Fillable PDF Form.

If you're asking if you can edit the PDF Form you uploaded through this page https://www.jotform.com/fillable-pdf-form-creator/ then yes, you may edit that form on your Form Builder.

HOWEVER, keep in mind that there are certain limitations when it comes to PDF forms (e.g. only certain fields will work, widgets will not work, payment processors will not work, conditions, and so on).

You can refer to this page: Everything-you-need-to-know-about-JotForm-Fillable-PDF-Creator to learn more about the things you can (or can't do) with Fillable PDF forms.

Not sure where to find the 'Edit Form' option I can only see 'Download PDF'. It is quite a complex form and I was hoping not to have to redo it in Jotform so really hope you can help me out.

We apologize for the confusion. I see now that you meant you want to Edit the Submission PDF report of the form.

You can follow the guide on this similar discussion thread.

In the Download PDF you should see 'Customize PDF' below it. That is the PDF Designer/Editor tool.

Thank you but I was looking to change the original form not each individual submission.  Have decided to create the form in Jotform

Thanks for letting us know, Mandy.

Should you have more questions, please let us know.

Thanks.
