The files uploaded to the form submissions will be stored in the JotForm servers and can be viewed/downloaded from your form submissions. The storage space of the account varies from the subscription plan that you are having and you may check our pricing page for the storage space provided for each subscription plan.

If you want, you may also integrate Google Drive, DropBox, Box with your forms so that the files will also be stored in the cloud storage chosen.
