One GB represents one billion bytes of billable usage. For most Robots that transform files, we add the input and output file sizes. Processing an 800 MB input into a 200 MB output therefore uses 1 GB.

Because file sizes and workflows differ, one GB is not a fixed number of files or operations. It could cover one large conversion or many small ones. Use the usage estimator for a practical workflow estimate, and see the Robot pricing page for the exact usage rules of each Robot.
