Sry, something wrong with attached file. It wasn't 256 color, here is correct one https://workupload.com/file/N2nWPR9C3sm

Ok, will be fixed

Thanks, would be nice especially if it would be handled by nconvert by default without additional commands.

Main nconvert page says that now it contains v7.135 but in fact its still older v7.121 (at least for Windows, both x64 and x86).

But how to get actual info about upcoming update then coz it's not like this page viewtopic.php?f=57&t=42650 updates frequently?

So in new version now it works with "-merge_alpha -truecolors" flags but would be better if handled by default without any additional commands. But thx anyway...

So far problem still exist: for example if nconvert spots "fake" png that is webp for real then it's removes transparency again if used "-merge_alpha -truecolors". But "-32bits" works fine - I think it should be suggested for me instead others.

Example image https://workupload.com/file/rRzT87t2aNa and command "nconvert -merge_alpha -truecolors -out webp -o oner.webp oner.png" but maybe it's not bug and such behaviour (removing transparency) is intended for webp files with those commands. Anyway I found a command "-32bits" that works fine in my case when nconvert couldn't convert (at least without transparency loss) png images to webp made with 256 colors so for me problem is solved.
