Cloudflare R2 Presigned Url limit file size

I’m trying to build a service using the Cloudflare r2 service.
I would like to use the presigned url method to let the user upload the file to ease the burden on the server.
However, I want to specify the maximum size of the file on the url to protect the service from malicious users, is there any way?
Or can I limit the upload size to less in my r2 account settings?

Hey!

We have already some limitations:

You can always add an IP access Rule to prevent another sources to perform such actions.

Take care!

Can i set custom limit?
