From the Canon website:
"For portable and wireless digital photography workflows, Canon's Digital Photo Professional Express (DPP Express) brings the powerful features of Canon's DPP software to your compatible iPad. Working with Canon's Camera Connect app*, DPP Express streamlines the processing of JPEGs and .CR3 RAW files with an intuitive and powerful interface. View images and adjust settings right on your mobile device, and save files to the cloud, a computer or your camera. With DPP Express, it's incredibly easy to maintain a wireless RAW workflow on the go.
