Where do people go to access my fillable form?

were do people go to access my fillable form? Do I have to have a website or can they complete the form and it will be emailed to me?

To create a form they can fill online, go ahead and create the form and it will be accessible on a Jotform URL. Refer to this guide: Where to Find My Form URL

As for the Fillable PDF, you can download it and share the file over Email with friends. Once the form is filled, the user can click the submit button and the data will be submitted. Refer to this guide: How to Create a PDF Form

In summary, you can have 2 versions of the form. The online form that can be accessed via URL or embedded on a website and the offline form that can be downloaded as a PDF and shared. For the offline form, submitting it still requires an internet connection.

Both forms once submitted have their data visible in the submissions: https://www.jotform.com/help/269-How-to-View-Form-Submissions
