Even if your original image dimensions are odd, you can avoid blurring when scaling down by selecting "None" as the interpolation method in the Scale Image dialog:


Select Scale Image... from the Image menu.
Select "percent" as the unit in the Image Size section.
Enter "50" as the width and press enter. GIMP will set both the width and the height to 50%, and round them up to the nearest pixel.
Select the interpolation method "None" in the Quality section.


Click the Scale button.
