Formidable Forms is the plugin needed to create the web form(s). The free version works great, but there are a lot of features missing, this page displays what is included and what is missing from the free version.
Formidable PRO2PDF is our plugin, which is needed to merge Formidable Forms to PDF Forms – The free option offers up to 1 Form but there are a lot of features missing, paid options have all features included… 2 Forms ($15), 10 Forms ($25), 40 Forms ($40) and Unlimited Forms ($99) – you choose which subscription you need. You can upgrade at anytime using the upgrade page.
You also need a program or app to build your PDF Forms. You can use Adobe Acrobat, or PDFEscape.com, or any other PDF Form making program (except Adobe LiveCycle forms).
We remain at your service and look forward to helping you with your need to fillin PDF forms from WordPress.
