A CDR file is a vector drawing image file that is natively created with CorelDRAW for storing digital image encoded and compressed. Such a drawing file contains text, lines, shapes, images, colours and effects for vector representation of image contents. CDR files can be opened with CorelDRAW as the primary application and can also be converted to other formats such as PDF, JPG, PNG, BMP and AI.
