You can use ACDSee 12 to convert an image to any of these color depths. However, to use certain image enhancement tools, filters, blends, and adjustment options, the image must be Hicolor or Truecolor. To edit an image that is not originally Hicolor or Truecolor, you can convert it, edit the image, and then convert it back to its original color depth.
