Can I limit the file size in an Upload widget?
Application Type

Hi there.

I was wondering if there's a way to limit the size of the Image/File that the user can upload through an Upload widget?

Thanks in advance.

If you use this forge component you can set the MaxFileSize:

Hello Yizuhi ,

Hi Yizuhi,

In my case, in the screen actions, we can put a check using BinaryDataSize function as the following

BinaryDataSize(UploadWidget.Content) > (Site.FileUploadMaxSizeMB * 1000000)

Hope it helps

Where this BinaryDataSize function is available?


Thanks Again. I Found It!
