    Is there a limit to the size of an uploaded file.

    Asked by Nancy Caulfield on April 12, 2017 at 06:37 PM

    In testing my live form, I asked my daughter to submit the form with a file.  She tried to upload a video file of 579.7 MB. when she selected the submit button, the form hung at Please wait for a long time and then finally she got a message that said,"... there are incomplete values in your form. Please go back & fix." Then, when she clicked "go back" it's a blank form?

    1.  Is there a file size limit?

    2.  When she clicks Go Back, the form should not be blank.

    When she submits the form with a smaller file 12.5 MB it all worked correctly.  

    I need to know if I need to let ppl uploading files that there is a limit to the file size and if so, what is it?

    Please allow me to inform you that the JotForm Upload max size is 1 GB or less per file. You can read more in this guide about the JotForm Upload Size Limit: Changing the File Upload Size Limit.

    To prevent this issue you are encountering, please try setting a  minimum and maximum file size limit and see if this helps to solve the issue.
