Yeah, webp uploads not welcome. Can handle more gracefully? Sure.

Sounds good. Curious why you don't like webp images? I don't mind either way, just curious.

I don't mind then. The library we use allows jpg, png and gif only. I will see if there's an updated version before blocking.

Intune and others also don't like them. Somewhat a browser encode.

Browser extension 'save as image' and the issue be gone.
