GIMP How to make fuzzy border transparent

| Posted in Software
  • Do not use the “Flatten Image” option. A new layer will be created containing only the border (this layer will be the active layer).
  • Perform “Layer->Transparency->Alpha to Selection”
  • Perform “Layer->Delete”. (you don’t need this layer any more)
  • Perform “Layer->Transparency->Add Alpha Channel” (if possible)
  • Perform “Edit->Clear”
  • Note: the “Layer” commands are also available on the context menu accessed by right-clicking on the layer’s thumbnail preview in the Layer Dialog.
