JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
Please be noted that the max file that can be uploaded is 1GB. However, it is required to have a paid subscription to get more storage space since Free subscription plan is restricted to store only up to 100MB. If you want to change the file upload limit of a upload field, you may change it by changing the value in Max File Size option.
Hope this information helps!
