What is the file size limit for uploading an image/document on JotForm?

Are you planning to allow your user to upload a file in your form using the File Upload field? If yes, then please refer to this guide: Changing-the-File-Upload-Size-Limit.

The maximum upload size limit per submission is 1gb.

If you are referring to the images that you will upload to your account, then please keep in mind that the upload space for the Free plan is only 100mb. Please check our pricing page for more details.

If you need more than 100mb, I recommend you upgrade your account.

Hope that helps. Thank you.
