How can I combine several individual .ico files into a single file?

Question

I was able to convert PNG files into ICO files (thanks to Turn pngs to one ICO file ), but now I would like to create an icon "bundle" similar to system32.dll, which contains several individual icons. How can this be done?

You need to build a DLL that contains multiple icons as resources. That can be done from Visual Studio via these instructions. Other Windows development tools that can create a DLL should be able to do the same thing.

This could even been done with the resource compiler (rc.exe) that is included in the Windows SDK and manually creating a resource file.

Looks like this will work as well.

This uses a Flash-based file uploader, and does not work any more. – Sebastian Mar 04 '21 at 10:24
Are there any alternatives that don't use Flash? – Logic1 Oct 17 '21 at 11:31

There is a program could meet your requirement. It's GConvert: https://www.gdgsoft.com/gconvert

But so far, this freeware only support 256x256 size. If you ok with that then you may wanna give it a shot.

It turns out that there was a Java rewrite of CombineIcons called Icollator, although it still only supports up to 128x128 pixels.

This doesn't work, the output file only contains one of the icons. – Donald Duck Nov 06 '21 at 12:31
