Description

Hello

When I use the command:

magick convert favicon.png -alpha on -resize 256x256 -define icon:auto-resize="256,128,96,64,48,32,16" favicon.ico

favicon.ico is created with a resolution of 128x128 (Not maximum - 256x256).

Steps to Reproduce

If open the favicon.ico file in Photoshop, then I can select a resolution of 256x256 or 128x128 or 96x96 etc. How I can get 256x256 when creating a default .ico file in a folder?

Please state the exact IM version. You can paste the text output from "magick -version".

Please show your input favicon.png.

I suggest using "magick", not "magick convert".

But in windows 7 when creating the favicon.ico file:

The first row says:

favicon.ico[0] PNG 256x256 256x256+0+0 8-bit sRGB 18934B 0.000u 0:00.001

So 256x256 is the biggest resolution. I have no clue what your Windows Properties is showing or trying to find since it is a multi-resolution file. Perhaps it is just showing the resolution it used for the preview.
