How to convert 16 bit PNG to 16 bit TIF?

Hi,

if I convert a 16 bit PNG to a TIFF than the 16 bit color depth is lost. Is it a bug or do I need to set the right parameter only?

Image data is 8bits per component internally, only NConvert can convert 16bits to 16bits

Sounds good. I tried it but ... "WARNING: the picture will be converted to RGB with 8bits per component". Did I have overseen an option?

Pierre is referring to NConvert the command line utility, if that could be a source of confusion?

Thank you for the hint. I tested it at NConvert with UI. So, I will look for how to use the command line tool.
