Why convert AVIF to ICO?
- Transparent areas stay transparent: ICO supports smooth, partial transparency just like AVIF.
- One ICO bundles the standard 16 to 256 px icon sizes (up to the size of your image), ready for a favicon.ico or a Windows shortcut.
What to expect when converting AVIF to ICO
- 图标是正方形的，因此非正方形图片会居中放置在透明正方形上。不会生成比您的图片更大的尺寸，所以请从至少 256 × 256 像素的图片开始。
- 您原来的 AVIF 文件不会被更改：您下载的是一份新的 ICO 副本。
