A CDR file is a vector image file created with CorelDRAW, a vector illustration and page layout design application included in the CorelDRAW Graphics Suite. CDR files primarily contain vector image data, such as lines, paths, shapes, and colors, but they can also include text, raster images, effects, and other elements. CDR files are often used to create brochures, posters, logos, web banners, and other graphic design projects. While CorelDRAW is the leading software for opening and editing CDR files, other Corel products, like Corel PHOTO-PAINT, can also open CDR files with limited editing capabilities.
