.CDR File Extension

A CDR file is a drawing (or vector image) created with CorelDRAW, a vector illustration and page layout program. It contains a document that contains text, lines, shapes, images, colors, and effects. CDR files are used to create various types of documents such as letters, brochures, tabloids, envelopes, post cards, web pages, and web banners.

CDR file open in CorelDRAW X8

The CDR file is the main file type created by CorelDRAW. When you save your document in the CDR format, CorelDRAW creates the CDR file to store the contents of the documents. You can save a CDR file by selecting File → Save.

If you come across a CDR file on your computer it most likely is a drawing created by CorelDRAW. Since CDR files are saved in a proprietary format used by Corel software not many image editing programs support the format. However, you can export the CDR file in CorelDRAW to other more popular formats such as .PDF, .JPG, .PNG, .BMP, and .AI.

You can save a CDR file as a template if you want to reuse the document layout again. To create a template, select File → Save as Template.... CorelDRAW will save the template as a .CDT file.

CorelDRAW is included in the CorelDRAW Graphics Suite along with the following applications:

• Corel PHOTO-PAINT - An image-editing application for digital photos
• Corel CAPTURE - A single-click screen capture utility
• Corel CONNECT - A built-in content organizer
