I have used the Studio to convert a 256 pixel PNG into an ICO with transparency
put its only 256. ICOs can (should) be multi-resolution 16, 32, 64, 128 AND 256 pixels sqaure.
Try something like this...
Code: Select all
convert input.png -define icon:auto-resize="256,128,64,32,16" result.ico
If you're using ImageMagick version 7 use "magick" instead of "convert".
