It uses the ability of GIMP to have each layer a different size.
I created the following layers sized correctly.
256x256 will be saved as 32bpp 8bit alpha
48x48 will be saved as 32bpp 8bit alpha
48x48 will be saved as 8bpp 1bit alpha
32x32 will be saved as 32bpp 8bit alpha
32x32 will be saved as 8bpp 1bit alpha
32x32 will be saved as 4bpp 1bit alpha
16x16 will be saved as 32bpp 8bit alpha
16x16 will be saved as 8bpp 1bit alpha
16x16 will be saved as 4bpp 1bit alpha
Notes
You may need to check other resources to confirm to yourself that this is a sensible list of resolutions and colour depths.
Make sure you use transparency round the outside of your image, and anti-aliased edges. You should see the grey checkerboard effect round the outside of your layers to indicate they are transparent
The 16x16 icons will need to be heavily edited by hand using a 1 pixel wide pencil and the eyedropper tool to make them look any good.
Do not change colour depth / Mode in GIMP. Leave it as RGB
You change the colour depths when you save as an .ico - GIMP pops up a special dialog box for changing the colour settings for each layer
The excellent (free trial) IcoFX allows you to create and edit icons, including multiple sizes up to 256x256, PNG compression, and transparency. I highly recommend it over most of the alternates.
Get your copy here: http://icofx.ro/ . It supports Windows XP onwards.
Windows automatically chooses the proper icon from the file, depending on where it is to be displayed. For more information on icon design and the sizes/bit depths you should include, see these references:
What i do is to prepare a 512x512 PNG, the Alpha Channel is good for rounded corners or drop shadows, then I upload it to this site http://convertico.com/, and for free then it returns me a 6 sizes .ico file with 256x256, 128x128, 64x64, 48x48, 32x32 and 16x16 sizes.
I found an app for Mac OSX called ICOBundle that allows you to easily drop a selection of ico files in different sizes onto the ICOBundle.app, prompts you for a folder destination and file name, and it creates the multi-icon .ico file.
Now if it were only possible to mix-in an animated gif version into that one file it'd be a complete icon set, sadly not possible and requires a separate file and code snippet.

这可以使用 GIMP 免费完成。
它使用 GIMP 的功能使每个层具有不同的大小。
我创建了以下尺寸正确的图层。
注意
This can be done for free using GIMP.

Notes
ImageMagick，免费开源的图像处理工具包，可以轻松做到这一点：
注意：从 ImageMagick 7 开始，CLI 略有变化，您需要在前面添加
magick任何命令。另请参阅http://www.imagemagick.org/Usage/thumbnails/#favicon ，有这样的例子：
现在还有更短的：
ImageMagick, the free and open source image manipulation toolkit, can easily do this:
Note: Since ImageMagick 7, the CLI has changed slightly, you need to add
magickin front of any commands.See also http://www.imagemagick.org/Usage/thumbnails/#favicon, that has the example:
There is also now the shorter:
优秀的（免费试用）IcoFX 允许您创建和编辑图标，包括高达 256x256 的多种尺寸、PNG 压缩和透明度。我强烈推荐它而不是大多数替代品。
在此处获取副本：http://icofx.ro/ 。它支持 Windows XP 及以上版本。
Windows 会根据文件的显示位置自动从文件中选择正确的图标。

我所做的是准备一个 512x512 PNG，Alpha 通道适合圆角或阴影，然后我将其上传到此网站 http ://convertico.com/，然后它免费返回给我一个 6 种尺寸的 .ico 文件，尺寸为 256x256、128x128、64x64、48x48、32x32 和 16x16。

Visual Studio资源编辑器（VS 2013社区版免费）可以导入PNG（和其他格式）并导出ICO。

我发现了一个名为 ICOBundle 的 Mac OSX 应用程序，它允许您轻松地将不同大小的 ico 文件拖放到 ICOBundle.app 上，提示您输入文件夹目标和文件名，并创建多图标 .ico 文件。
现在如果只能将动画 gif 版本混合到该文件中，这将是一个完整的图标集，遗憾的是不可能，并且需要单独的文件和代码片段。
