CPH is a file format used by Corel Print House software application. The application is no longer developed and some of its functionalities were moved to different tools included in CorelDRAW package, which is updated on a yearly basis. CorelDRAW can be thus used to open and edit CPH files.

CPH format was created for storing printable documents. It was used mainly for smaller marketing-related projects such as calendars, banners, or leaflets. Corel Print House was also used by private users for creating photo albums or note cards.
