2.12. Export…

This command is called Export for a native XCF file. Then, it does the same thing as Export As…. At early GIMP 2.8 releases, this menu label was Export to. Since the version 2.8.10, Export to and Export have been renamed to Export and Export As after the manner of Save and Save As.

The name becomes Overwriting name.extension for an imported image. So, you can export the imported image directly in its original file format, without going through the export dialog.
