    Upload File Form Issue (Max size)

    Asked by sdsign on March 03, 2014 at 05:57 PM


    I created a upload file form.

    According to this article (http://www.jotform.com/help/33-Changing-the-Upload-Size-Limit), it should be able to upload file up to 1GB for box.com or 5GB for Google Drive, so I integrated with box.com and google drive with 1GB Max File Size.

    It, however, keeps spinning forever and fails when I tried to upload a 700MB TIFF file.

    In the form, I set up: File Upload Button with 1048576KB, Allow Multiple, Secure Embeded code

    JotForm Plan: Economy

    Box.com: Enterprize plan


    Please give me any advise to fix this issue.


    Thank you.

    For larger file uploads (about more than 250MB), I suggest to NOT use the "Allow Multiple" option of the upload field, as it becomes unstable for larger files. Use the Single option only.

    If you need to use multiple uploading per session, you can just add multiple single upload field on the form.

    You should also take into consideration that the maximum file size allowe per upload session is 1 GB only . So, if you have multiple uploads that will exceed the session limits, the upload will fail.

    Uploading large file can also take time. Make sure there is no time-out session or disconnection that will occur during this time.

    Hope this help. Inform us if there are still issue.

    Hi Jonathan,

    Thank you for your quick response.

    I changed the setting without the 'multiple upload'.

    I'm testing right now, but is it normal to take such a long time to attached files in the form?

    When I tested attaching 500MB or 700MB to the JotForm, it takes 20 or 30 min. (keep spinning forever...)

    Is there any way to make it quick?

    Please advise.

    Thank you.

    Hello sdsign,

    Unfortunately, there is no way to make the upload process quick.

    Upload time actually depends primarily on your own internet speed. The speed depends on the hosting company, clients hardware and software, and the most important is client's ISP. 

    What is your internet speed which your ISP provides? Please check it at http://www.speedtest.net? Please check and get back to us.

    Thank you!

    Hi ashwin_d,

    Thank you for your response.

    I checked the speed test, and got this result.

    PING: 26ms
    Download Speed: 49.86Mbps
    Upload Speed: 47.29Mbps

    I have no issue attaching/uploading heavy files with another file upload system such as WeTransfer or 3rd party system.

    Please give me advise and hopefully I can fix this issue.

    Thank you.

    You have not been cleared though if you are still not abel to successfully upload the files?

    It may take long for larger file size, but it should be uploaded successfully. 

    Are you able to complete submission of the form? 

    Your interent speed is very much able to upload the maximum allowed file size on the form.

    It could be a different reason if submission/uploading is not successful





    To be honest, JotForm is not actually a dedicated file uploading service, so I am sure it will not be able to compare on that regard to other service which offer that service specifically.

    Hi Jonathan,

    Thank you for your info.

    I understand that the JotForm is not a dedicated file uploading service.

    I need to find another direction for solving the issue.


    Thank you.
