convert produces images of the same type as the input and not the type of the output file

[dvir]

and this delegates for the broken version:
CODE: SELECT ALL
DELEGATES bzlib freetype jng jpeg png ps xml zlib

PNG seems to be in both systems. However, this list does not always mean that the delegate is really there and working.


You may need to check the versions of each using

convert -list format

If PNG is not listed in the bad IM version, then it was not truly installed properly. Still it could be there an corrupt. So it might need reinstalling and if so, try to upgrade it.

thanks, this was exactly the issue! libpng wasn't installed correctly.

Thanks you so much fmw42! Your help has saved me a lot of time.
