Every now and then I see a user who complains that CorelDRAW can’t open a JPG or TIF or some other bitmap format. That’s correct, you can’t open any bitmap format in CorelDRAW. If you instead use the import command, they should work just fine.
Remember that CorelDRAW’s primary purpose is editing vector graphics. That’s why you can’t “open” bitmap files. If you need to open bitmaps for editing, use Corel PHOTO-PAINT instead. With this team of programs, you can edit a wide variety of vector and bitmap graphics.
