Dear Pierre,

I have the same problem. I found that conversion gives unaccepteble results (white background instead of transparency, distorted edges) if the bitdepth of the input PNG file is not 24bpp (8bpp for example).
could you have a look at this please I would be more than grateful indeed.

Kind regards,
Endre

Welcome to the forum, ucsendre.

This is a known issue. Please make sure to increase the color to 32-bit before converting this kind of images.
