Safe Way to Create a .ico file?

[glaustin]

Hi Guys

I want to create some custom icons for Win10 folders. I don't want to export to a web converter or install a plug-in unless there's an officially approved version.

I understand I can create a png file and either use that direct or change the extension to '.ico' and that will do the trick. Is that just wishful thinking or is it a realistic option? If so, can anyone give me a hint on file size, please?

There are plug-ins for .ico support

Changing the extension from PNG to ICO does appear to work for using as a favicon for a website.

If you want a custom folder icon for Windows (I don't use mac, so I cannot speak to that) you can do this:

(note that it will NOT have a transparent background)

• Create the graphic
• If created in Illustrator, bring it into Photoshop
• Save the Photoshop file as a BMP
• Change the file extension to ICO

If a "free" website can do it, why can't one Adobe developer knock out this simple quality-of-life option on a coffee break?
