GIMP 2.10 is among the best freeware image-editing applications for Windows. It includes an abundance of image-editing utilities.

  10. If you need to, click the Move Tool again so that you can better align the mirrored image along the bottom of the one in the top half of the canvas.
  11. You can add some optional opacity to the flipped image reflection by selecting its layer on the right of the window and reducing the Opacity value to something like 50. Then the flipped reflection will be faded.The opacity effect flip tool / mirror image gimp
