What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Unfortunately, it is not possible to use the web form offline. The form needs to be online to display properly and send the submissions to your jotform account, so you cannot collect submissions using the form if there is no internet connection.
The only way you can allow users to fill the form offline is if you convert the form into a Fillable PDF. Here's a guide on How to create a PDF form. By turning the form into a Fillable PDF, your users will be able to fill in the PDF form and save it while they are offline. Then once they have an internet connection, they can simply submit the PDF form so that it will be recorded on your Jotform account's submissions page.
