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.
The maximum file size that you can upload on your form is 1GB. If you integrated the form with Dropbox, then the maximum file size is 300MB. Files over 300MB are not forwarded to Dropbox, but you can still download them from your JotForm storage. However, please note that Free accounts can have an upload space of 100MB, so if you want to receive files with larger sizes, then you may need to upgrade your account to a higher plan.
For more information about the upload limit, you can check out this guide: Changing the upload size limit.
