A CDR file is a vector drawing image file that is natively created with CorelDRAW for storing digital images encoded and compressed. Such a drawing file contains text, lines, shapes, images, colors, and effects for vector representation of image contents. It can be used for the representation of various graphics data like brochures, tabloids, envelopes, and postcards. Besides CorelDRAW, other Corel products such as Corel Paintshop Pro and CorelDRAW Graphics suite can also open the CDR file formats.
