3. 点击图标 → 选择 Download SVG file 按钮。

定制专属SVG图标

1. 用记事本/VSCode等工具打开下载的 xxx.svg 文件。

2. 把步骤1中的源代码喂给 DeepSeek，再写上你的修改要求，提交等待生成。

3. 粘贴步骤2DeepSeek生成的源代码，另存为 icon.svg 。

生成多尺寸ICO文件

1. 下载并安装Windows 二进制文件版本。

2. 在终端中执行下面的命令（文件目录cmd）

初始版

rem 1. 生成各尺寸 PNG
magick icon.svg -resize 256x256 256.png  
magick icon.svg -resize 128x128 128.png  
magick icon.svg -resize 64x64 64.png  
magick icon.svg -resize 48x48 48.png  
magick icon.svg -resize 32x32 32.png  
magick icon.svg -resize 16x16 16.png  

rem 2. 合并为 ICO
magick 256.png 128.png 64.png 48.png 32.png 16.png -compress none app.ico
