Merge Visible Layers will combine currently visible layers to one layer, invisible layers aren't effected and will stay as before the merge. There are three ways to merge visible layers.

Expanded as necessary:

The final layer has the size of the biggest layer of all of the visible layers. (Remember that a layer in Gimp can be bigger than the image)

Clipped to image:

Will set the final layer size equal to the image size. (Remember that layers in Gimp can be bigger than the image it self. If you have such a visible layer it will be clipped to the image size).

Clipped to bottom layer:

Will set the final layer size equal to the bottom layer. If the bottom layer is smaller than any of your visible layers. The final layer will be clipped and trimmed according to both the size and position of the bottom layer.
