Can I limit file upload size?

Yes, you can limit file upload size, although there is already a 150 MB limit cap. This means that form users cannot upload files bigger than 150 MB each. You can opt for an upload field which accepts multiple files.

To limit file upload size, go to your Form Editor, click on the File Upload field in your form and its Edit Field panel will open up on the left side of the page. In the Maximum Upload Size box, type your preferred maximum size (in KB). If you want to add a minimum upload size limit, type in the Minimum Upload Size box. That’s it.

  1. Hello.

    Is it possible to set different size limits for different file extentions in the same upload field? Would be very convenient in some cases.

    1. Hi Alex,

      The size limit can only be set per File Upload field, and not to a particular file extension type.

      It is possible, however, to use a Single choice field along with multiple File Upload fields set up. The Single choice field would include the available file extensions and, each File Upload field would allow only a single file extension an have the desired maximum file size applied.

      Finally, field rules can be set up to display a certain File Upload field with the equivalent file size limit and extension, based on the file type selected from the Single choice field.

      Thanks.
