Good morning.
Is it possible to keep the transparency color of PNG files when converting to GIF? If yes how can I do it? I tried of many ways and I did not could to do it.
XnView should keep the transparency If the PNG uses palette transparency, but if the PNG uses alpha transparency, then XnView cannot keep the transparency when converting to GIF, because GIF format doesn't support alpha transparency.
