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.
There is a limit of 1GB per upload, so, this means you cannot do the 2.5GB in one go. But since you have a 10GB max upload space on your subscription, you can also put instructions to do the process of uploading in your form divided into 1GB per upload.
Please inform us if you have any other inquiry.
Sorry but we can't see your latest message if you have responded to your thread here. May we suggest you to post it directly on this thread instead http://www.jotform.com/answers/129053 so we can help you further if that's a question.
