Ninja Forms – PDF Form Submissions enables you to automatically attach a PDF copy of the form submission with any notification email. More than this, you can also go into the WordPress admin and download a PDF copy of any submitted form.
To continue, PDFs standardize the format that you have for a more professional look. In addition, you will replace the often difficult to parse CSV documents that WordPress defaults with a PDF template. Hence, the PDF format is much more easier to customize and share.
