Windows has many icons which can be used for your link or app customization. Toons on icons can be found on internet , but what if you prefer to do this self? Make custom icon? The best way is to do this with tools which are free , clean and probably usable for many others needs.
It is easy , you will need gimp and iconify script.
First one can be found at https://www.gimp.org/downloads/ second is harder to find. Main page where scripts for gimp were kept is not online any more, but page was ripped to static html site and hosted on Github. Here is a link https://github.com/pixlsus/registry.gimp.org_static/blob/master/registry.gimp.org/files/iconify2_1.scm .
Saving script please select RAW button , you will see clean text file with extension scm and file save in (%username%) is a name of your windows user.
Then restart gimp or refresh scripts by command from menu
