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.
Files with WMF extension represent Microsoft Windows Metafile (WMF) for storing vector as well as bitmap-format images data. To be more accurate, WMF belongs to the vector file format category of Graphics file formats that is device independent. Windows Graphical Device Interface (GDI) uses the functions stored in a WMF file to display an image on the screen.
You can also convert CDR into many other file formats. Please see the complete list below.
