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.
Yes, our form supports secure protocol. You can simply switch your form URL from http to https for additional security capabilities.
Free users disk space limit is 100MB (more info on our pricing page). File upload limit can go up to 1GB per upload but it's pretty useless when you are on free account so upgrading to Premium is a good option if you'd really have large file uploads on your forms.
Just an update. Our developers have added a new security layer to make your file uploads more secure. You can learn more about it on this blog post: https://www.jotform.com/blog/259-Keeping-Your-Uploads-Secure
