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.
Do you mean you want to have an upload feature in your form? If so, you just need to add the File Upload Field in your form.
Once you have the File Upload field on your form, upon viewing the form, you can upload a file by clicking the Choose File button.
Then to download the file uploaded by your user, you can check it on the Form's Submission page.
If you are referring to a different concern, please provide us further information so we can further check your concern.
