Upload Limit File Size

I manage the photos of a homepage by linking to a NC folder. I now want to limit the file size when uploading so that the photos are not too large in file size. Is there a file size limiter or similar for this? So some tool that only uploads images up to a set file size?
I don’t want to change the total storage usage of a user, that doesn’t do any good.
I don’t want certain users to upload photos with a file size over 700Kb.

Afaik, that kind of functions doesn’t exist (yet). It might be possible that you can use one of the available flow apps to run checks or automatically delete files which size is over a defined threshold.
