Convert an image to ICO, the icon file a website and a program use.
The ICO converter writes a multi-size icon file from your picture.
What size should the picture be?
A square of 512 pixels or more; the sizes below it are made for you.
Can I make a favicon from a photo?
Yes, but a picture with one shape in it reads better as an icon.
Input: format, quality. No account needed within the free limit; a token with tools.tool.run raises it.
