You can create screenshots to share with your friends or colleagues.
Use the Camera icon from the menu to choose between a draft, HD render and a 4K render.
Tip: Picking the Draft quality won’t spend your render slots but will create a screenshot that can be shared. Always create a draft first. If you like it, you can always convert it to HD from the "Renders" section.
Note that 4K renders are available with the Pro susbcription.
