如何制作网站图标
- 拖放或选择要转换为网站图标的图片。
- 选择需要的尺寸（从16×16到512×512）。
- 下载单个PNG或保存为ICO文件。
The favicon generator turns a single image into the icon shown on browser tabs and bookmarks. Upload a logo or picture and it creates every size you need, from 16×16 to 512×512, and can also save a broadly compatible ICO file.
Which sizes do you need?
Browser tabs and bookmarks use 16×16 and 32×32, while high-resolution screens and mobile home screens use 180×180, 192×192, and 512×512. Pick the sizes you want and download them all at once instead of making each one separately.
Tips for a good favicon
Because a favicon appears very small, a simple symbol reads better than a detailed image. Use a square image, and prefer a PNG original if you need a transparent background. If your source isn't square, square it up first with the crop tool.
